Exercise 2:Read the following passage on transport, and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions
Traditionally in America, helping the poor was a matter for private charities or local governments
Arriving immigrants depended mainly on predecessors from their homeland to help them start a new life
In the late 19th and early 20th centuries, several European nations instituted public-welfare programs But
such a movement was slow to take hold in the United States because the rapid pace of industrialization and the ready availability of farmland seemed to confirm the belief that anyone who was willing to work could find a job
Most of the programs started during the Depression era were temporary relief measures, but one of the programs - Social Security - has become an American institution Paid for by deductions from the
paychecks of working people, Social Security ensures that retired persons receive a modest monthly income and also provides unemployment insurance, disability insurance, and other assistance to those who need it Social Security payments to retired persons can start at age 62, but many wait until age 65, when the payments are slightly higher Recently, there has been concern that the Social Security fund may not have enough money to fulfill its obligations in the 21st century, when the population of elderly Americans is expected to increase dramatically Policy makers have proposed various ways to make up the anticipated deficit, but a long-term solution is still being debated
In the years since Roosevelt, other American presidents have established assistance programs These include Medicaid and Medicare; food stamps, certificates that people can use to purchase food; and public housing which is built at federal expense and made available to persons on low incomes
Needy Americans can also turn to sources other than the government for help A broad spectrum of private charities and voluntary organizations is available Volunteerism is on the rise in the United States,
Trang 3especially among retired persons It is estimated that almost 50 percent of Americans over age 18 do volunteer work, and nearly 75 percent of U.S households contribute money to charity
Question 6 The passage mainly discusses
A public assistance in America B immigration into America
C funding agencies in America D ways of fund-raising in America
Question 7 New immigrants to the U.S could seek help from
A the people who came earlier B the US government agencies
C only charity organizations D volunteer organizations
Question 8 It took welfare programs a long time to gain a foothold in the U.S due to the fast growth
of
A industrialization B modernization C urbanization D population
Question 9 The word “instituted” in the first paragraph mostly means
Question 10 Most of the public assistance programs after the severe economic crisis
A were introduced into institutions B did not become institutionalized
C functioned fruitfully in institutions D did not work in institutions
Question 11 That Social Security payments will be a burden comes from the concern that
A elderly people ask for more money B the program discourages working people
C the number of elderly people is growing D younger people do not want to work
Question 12 Americans on low incomes can seek help from
Question 13 Public assistance has become more and more popular due to the
A young people’s voluntarism only B volunteer organizations

(1) A small but growing group of scholars, evolutionary psychologists, are beginning to sketch the
contours of the human mind as designed by natural selection Some of them even anticipate the coming
of a field called “mismatch theory”, which would study maladies resulting from contrasts between the
modern environment and the “ancestral environment” The one we were designed for.
Trang 4(2) There is no shortage of such maladies to study Rates of depression have been doubling in some industrial countries roughly every 10 years Suicide is the third most common cause of death among young adults, after car wrecks and homicides.
(3) Evolutionary psychology is a long way from explaining all this with precision, but it is already
shedding enough light to challenge some conventional wisdom It suggests, for example, that the
nostalgia for the nuclear family of the 1950s is in some way misguided that the model family of husband
at work and wife at home is hardly a “natural” and the healthful living arrangement, especially for the wives Moreover, the by gone lifestyles that do look fairly by commercialism Perhaps the biggest
surprise from evolutionary psychology is it depiction of the “animal” is us Freud, and various thinkers since, saw “civilization” as an oppressive force that thwarts basic animal instincts and urges and
transmutes them into psychopathology However, evolutionary psychology suggests that a large threat to mental health may be the way civilization thwarts civility There is a gentler, kinder side of human nature, and it seems increasingly to be a victim of repression in modern society
Question14: Which of the following is the theory that evolutionary psychologists forecast about its
appearance?

Whales are the largest animals in the world, and the gentlest creatures we know Although the whale is very huge, it is not hindered at all by its size when it is in the water Whales have tails that end like
flippers With just a gentle flick, it can propel itself forward The skin of a whale is so smooth that it does not create any friction that can slow the whale down A whale’s breathing hole is located on the top of its head, so it can breathe without having to completely push its head out of the water Whales are protected from the cold seawater by body fat that is called blubber
Whales live in the ocean but, in terms of behaviours, they are more similar to humans than fish They
live in family groups and they even travel in groups when they have to migrate from cooler to warmer waters The young stay with their parents for as long as fifteen years Whales are known not to desert the ill or injured members; instead, they cradle them
When whales are in danger, there are people who go to great lengths to help them One such case
occurred in 1988, when three young whales were trapped in the sea It was close to winter and the sea had begun to freeze over Whales are mammals that require oxygen from the air, so the frozen ice was a great
danger to them All they had then was a tiny hole in the ice for them to breathe through Volunteers from
all over soon turned up to help these creatures They cut holes in the ice to provide more breathing holes
for the whales These holes would also serve as guides for the whales so that they could swim to warmer

It's called 42 – the name taken from the answer to the meaning of life, from the science fiction series The
Hitchhiker's Guide to the Galaxy 42 was founded by French technology billionaire Xavier Niel, whose
backing means there are no tuition fees and accommodation is free Mr Niel and his co–founders come from the world of technology and start–ups, and they are trying to do to education what Facebook did to communication and Airbnb to accommodation
Students at 42 are given a choice of projects that they might be set in a job as a software engineer –
perhaps to design a website or a computer game They complete a project using resources freely
available on the Internet and by seeking help from their fellow students, who work alongside them in a
large open–plan room full of computers Another student will then be randomly assigned to mark their work
The founders claim this method of learning makes up for shortcomings in the traditional education
system, which they say encourages students to be passive recipients of knowledge "Peer–to–peer
learning develops students with the confidence to search for solutions by themselves, often in quite creative and ingenious ways."
Like in computer games, the students are asked to design and they go up a level by completing a project They graduate when they reach level 21, which usually takes three to five years And at the end, there is a
Trang 8certificate but no formal degree Recent graduates are now working at companies including IBM,
Amazon, and Tesla, as well as starting their own firms
"The feedback we have had from employers is that our graduates are more apt to go off and find out information for themselves, rather than asking their supervisors what to do next," says Brittany Bir, chief operating officer of 42 in California and a graduate of its sister school in Paris Ms Bir says 42's graduates will be better able to work with others and discuss and defend their ideas – an important skill in the “real world” of work "This is particularly important in computer programming, where individuals are
notorious for lacking certain human skills," she says.
But could 42's model of teacherless learning work in mainstream universities? Brittany Bir admits 42's methods do not suit all students "It suits individuals who are very disciplined and self–motivated, and who are not scared by having the freedom to work at their own pace," she says

Exercise 7: Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.
Scientists have experimented with a new procedure for alleviating the damage caused by strokes
Strokes are frequently caused by a blood clot lodging in the tree of arteries in the head, choking the flow
of blood Some brain cells die as a direct result of the stroke, but others also die over several hours because the proteins spilling out of the first cells that die trigger a chemical chain reaction that kills the neighboring cells
The current method of reducing the amount of damage is to give a clot dissolver, known as TPA, as soon as possible But generally TPA is not given to the patient until he or she reaches the hospital, and it still does not immediately stop the damage
The new technology, still in the research stage, involves chilling the area or the entire patient It is already known that when an organ is cooled, damage is slowed This is why sometimes a person who has fallen into an icy pond is not significantly harmed after being warmed up again The biggest issue is the method of cooling It is not feasible to chill the head alone Doctors have chilled the entire body by wrapping the patient in cold materials, but extreme shivering was a problem
The new idea is to cool the patient from the inside out Several companies are studying the use of cold-tipped catheters, inserted into the artery in the groin and threaded up to the inferior vena cava, which
is a large vein that supplies blood to the abdomen The catheter is expected to cool the blood that flows over it, thus allowing cooler blood to reach the area of the stroke damage
It is not expected that the cooling will be substantial, but even a slight decrease in temperature is thought to be helpful In effect, the patient is given a kind of forced hypothermia And doctors believe it is important to keep the patient awake so that they can converse with the patient in order to ascertain mental condition
Trang 10Studies continue to determine the most effective and least damaging means of cooling the patient in order to reduce this damage.

Question 41: According to the passage, the method of chilling from the inside out is being considered for
all of the following reasons except _
A it is not possible to chill the head alone
B cold dissolves blood clots

A some cells die immediately when a person has a stroke, and others die later
B the protein from dead cells kills other cells
C cells die only as a direct result of the stroke

Hobbit-like Species of Humans
On the tiny island of Flores, east of Bali and midway between Asia and Australia, the scientists
have discovered the remains of a small, hobbit-like species of humans These people grew no larger than
the modern three-year-old child They lived about 18,000 years ago and are completely different species
of human
Trang 11This discovery has taught scientists a lot about the human species This remarkable discovery shows that the human species is more varied and flexible in its ability to adapt than previously thought These hobbit-like people join a short list of other type of humans that lived with modern humans.
The researchers believe that these hobbits evolved from a normal size, human population that reached Flores around 840,000 years ago One likely explanation is that, over thousands of years, the species became smaller because the environmental conditions favored a smaller body size The dwarfing
of mammals on islands occurs frequently Islands limit food supply and predators and species compete for the same environmental space Survival would depend on minimizing energy requirements
Question 45: Which is the main topic of this passage?
A The reasons for the dwarfing of mammals
B Detailed information about the features of a different species of human
C The discovery of a hobbit-like species of human and its significance
D A fictitious character in world history
Question 46: What makes this discovery so significant?
A It shows that hobbits may have existed.
B This shows that small islands are good place for smaller species.
C It shows that humans do not need a lot of different foods.
D It shows that human can change a great deal according to the demands of the environment.
Question 47: The word “remains” in the passage is closest in meaning to _.
Question 48: Which of the following best favors a smaller body size?
A a mainland where there is a little competition for survival
B a small, isolated area where there is a limited food supply
C an island that has a large and varied food supply
D an environment where there are many predators

(1) The protozoans, minute, aquatic creatures each of which consists of a single cell of protoplasm,
constitute a classification of the most primitive forms of animal life They are fantastically diverse, but three major groups may be identified on the basis of their motility The Mastigophora have one or more long tails, which they use to project themselves forward The Ciliata, which use the same basic means for locomotion as the Mastigophora, have a larger number of short tails The Sarcodina, which include amoebae, float or row themselves about on their crusted bodies
(2) In addition to their form of movement, several other features discriminate among the three groups of
protozoans For example, at least two nuclei per cell have been identified in the Ciliata, usually a large nucleus that regulates growth but decomposes during reproduction, and a smaller one that contains the genetic code necessary to generate the large nucleus
(3) Protozoans are considered animals because, unlike pigmented plants to which some protozoans are
otherwise almost identical, they do not live on simple organic compounds Their cell demonstrates all of
the major characteristics of the cells of higher animals
(4) Many species of protozoans collect into colonies, physically connected to each other and responding
uniformly to outside stimulae Current research into this phenomenon, along with investigations carried
out with advanced microscopes may necessitate a redefinition of what constitutes protozoans, even calling into question the basic premise that they have only one cell Nevertheless, with the current data available, almost 40,000 species of protozoans have been identified No doubt, as the technology
improves our methods of observation, better models of classification will be proposed

(2) Cartoons in the West have been associated with political and social matters for many years In wartime, for example, they proved to be an excellent way of spreading propaganda Nowadays cartoons
Trang 16are often used to make short, sharp comments on politics and governments as well as on a variety of social matters In this way, the modern cartoon has become a very powerful force in influencing people in Europe and the United States
(3) Unlike most American and European cartoons, however, many Chinese cartoon drawings in the past have also attempted to educate people, especially those who could not read and write Such cartoons about the lives and sayings of great men in China have proved extremely useful in bringing education to illiterate and semi-literate people throughout China Confucius, Mencius and Laozi have all appeared in very interesting stories presented in the form of cartoons The cartoons themselves have thus served to illustrate the teachings of the Chinese sages in a very attractive way

depend chiefly on telling jokes Often, there is nothing to laugh at when you see Chinese cartoons This is
not their primary aim In addition to commenting on serious political and social matters, Chinese cartoons have aimed at spreading the traditional Chinese thoughts and culture as widely as possible among the people
(5) Today, however, Chinese cartoons have an added part to play in spreading knowledge They offer a very attractive and useful way of reaching people throughout the world, regardless of the particular country in which they live Thus, through cartoons, the thoughts and teachings of the old Chinese philosophers and sages can now reach people who live in such countries as Britain, France, America, Japan, Malaysia or Australia and who are unfamiliar with the Chinese culture
(6) Until recently, the transfer of knowledge and culture has been overwhelmingly from the West to the East and not vice versa By means of cartoons, however, publishing companies in Taiwan, Hong
Kong and Singapore are now having success in correcting this imbalance between the East and the West
(7) Cartoons can overcome language barriers in all foreign countries The vast increase in the popularity of these cartoons serves to illustrate the truth of Confucius’s famous saying “One picture is worth a thousand words.”

Exercise 13: Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.
(1) The ocean bottom - a region nearly 2.5 times greater than the total land area of the Earth - is a
vast frontier that even today is largely unexplored and uncharted Until about a century ago, the deepocean floor was completely inaccessible, hidden beneath waters averaging over 3,600 meters deep
Totally without light and subjected to intense pressures hundreds of times greater than at the Earth's surface, the deep-ocean bottom is a hostile environment to humans, in some ways as forbidding and remote as the void of outer space
(2) Although researchers have taken samples of deep-ocean rocks and sediments for over a century, the first detailed global investigation of the ocean bottom did not actually start until 1968, with the beginning of the National Science Foundation's Deep Sea Drilling Project (DSDP) Using techniques first developed for the offshore oil and gas industry, the DSDP's drill ship, the Glomar Challenger, was able to
Trang 18maintain a steady position on the ocean's surface and drill in very deep waters, extracting samples of sediments and rock from the ocean floor
(3) The Glomar Challenger completed 96 voyages in a 15-year research program that ended in November 1983 During this time, the vessel logged 600,000 kilometers and took almost 20,000 core samples of seabed sediments and rocks at 624 drilling sites around the world The Glomar Challenger's core samples have allowed geologists to reconstruct what the planet looked like hundreds of millions of years ago and to calculate what it will probably look like millions of years in the future Today, largely on
the strength of evidence gathered during the Glomar Challenger's voyages, nearly all earth scientists
agree on the theories of plate tectonics and continental drift that explain many of the geological processes that shape the Earth
(4) The cores of sediment drilled by the Glomar Challenger have also yielded information critical to understanding the world's past climates Deep-ocean sediments provide a climatic record stretching back
hundreds of millions of years, because they are largely isolated from the mechanical erosion and the
intense chemical and biological activity that rapidly destroy much land-based evidence of past climates This record has already provided insights into the patterns and causes of past climatic change - information that may be used to predict future climates
Question 79: The author refers to the ocean bottom as a "frontier" because it .
A is not a popular area for scientific research B contains a wide variety of life forms
C attracts courageous explorers D is an unknown territory
Question 80: The word "inaccessible" in the first paragraph is closest in meaning to .
Question 81: Which of the following is NOT true of the Glomar Challenger?
A It is a type of submarine B It is an ongoing project.
C It has gone on nearly 100 voyages D It made its first DSDP voyage in 1968.
Question 82: The deep Sea Drilling Project was significant because it was .
A an attempt to find new sources of oil and gas
B the first extensive exploration of the ocean bottom
C composed of geologists form all over the world
D funded entirely by the gas and oil industry

Trang 19(1) After the Anasazi abandoned southwestern Colorado in the late 1200s or early 1300s, history’s pages are blank The Anasazi were masons and apartment builders who occupied the deserts, river valleys, and mesas of this region for over a thousand years, building structures that have weathered the test of time
(2) The first Europeans to visit southwestern Colorado were the ever-restless, ambitious Spanish, who sought gold, pelts, and slaves In 1765, under orders from the Spanish governor in Santa Fe, Juan
Maria Antonio Rivera led a prospecting and trading party into the region Near the Dolores River in
southwestern Colorado, he found some insignificant silver-bearing rocks, and it is thought that it was he who named the mountains nearby the Sierra de la Plata or the Silver Mountains Rivera found little of commercial value that would interest his superiors in Santa Fe, but he did open up a route that would soon
lead to the establishment of the Old Spanish Trail This expedition and others to follow left names on the
land which are only reminders we have today that the Spanish once explored this region
(3) In 1776, one of the men who had accompanied Rivera, Andre Muniz, acted as a guide for another expedition That party entered southwestern Colorado in search of a route west to California, traveling near today’s towns of Durango and Dolores Along the way, they camped at the base of a large green mesa which today carries the name Mesa Verde They were the first Europeans to record the discovery of an Anasazi archeological site in southwestern Colorado
(4) By the early 1800s, American mountain men and trappers were exploring the area in their quest for beaver pelts Men like Peg-leg Smith were outfitted with supplies in the crossroads trapping town of Taos, New Mexico These adventurous American trappers were a tough bunch They, possibly more than any other newcomers, penetrated deeply into the mountain fastness of southwestern Colorado, bringing back valuable information about the area and discovering new routes through the mountains One of the trappers, William Becknell, the father of the Santa Fe Trail, camped in the area of Mesa Verde, where he found pottery shards, stone houses, and other Anasazi remains

(1) Though Edmund Halley was most famous because of his achievements as an astronomer, he was
a scientist of diverse interests and great skill In addition to studying the skies, Halley was also deeply interested in exploring the unknown depths of the oceans One of his lesser-known accomplishments that were quite remarkable was his design for a diving bell that facilitated exploration of the watery depths (2) The diving bell that Halley designed had a major advantage over the diving bells that were in use prior to his Earlier diving bells could only make use of the air contained within the bell itself, so divers had to surface when the air inside the bell ran low Halley’s bell was an improvement in that its
Trang 21design allowed for an additional supply of fresh air that enabled a crew of divers to remain underwater for several hours
(3) The diving contraption that Halley designed was in the shape of a bell that measured three feet across the top and five feet across the bottom and could hold several divers comfortably; it was open at
the bottom so that divers could swim in and out at will The bell was built of wood, which was first
heavily tarred to make it water repellent and was then covered with a half-ton sheet of lead to make the bell heavy enough to sink in water The bell shape held air inside for the divers to breathe as the bell sank
to the bottom
(4) The air inside the bell was not the only source of air for the divers to breathe, and it was this improvement that made Halley’s bell superior to its predecessors In addition to the air already in the bell, air was also supplied to the divers from a lead barrel that was lowered to the ocean floor close to the bell itself Air flowed through a leather pipe from the lead barrel on the ocean floor to the bell The diver could breathe the air from a position inside the bell, or he could move around outside the bell wearing a diving suit that consisted of a lead bell-shaped helmet with a glass viewing window and a leather body suit, with a leather pipe carrying fresh air from the diving bell to the helmet

(1) As the twentieth century began, the importance of formal education in the United States increased The frontier had mostly disappeared and by 1910 most Americans lived in towns and cities Industrialization and the bureaucratization of economic life combined with a new emphasis upon
Trang 22credentials and expertise to make schooling increasingly important for economic and social mobility Increasingly, too, schools were viewed as the most important means of integrating immigrants into American society
(2) The arrival of a great wave of southern and eastern European immigrants at the turn of the
century coincided with and contributed to an enormous expansion of formal schooling By 1920
schooling to age fourteen or beyond was compulsory in most states, and the school year was greatly lengthened Kindergartens, vacation schools, extracurricular activities, and vocational education and counseling extended the influence of public schools over the lives of students, many of whom in the larger industrial cities were the children of immigrants Classes for adult immigrants were sponsored by public schools, corporations, unions, churches, settlement houses, and other agencies
(3) Reformers early in the twentieth century suggested that education programs should suit the needs of specific populations Immigrant women were once such population Schools tried to educate young women so they could occupy productive places in the urban industrial economy, and one place many educators considered appropriate for women was the home
(4) Although looking after the house and family was familiar to immigrant women, American education gave homemaking a new definition In preindustrial economies, homemaking had meant the
production as well as the consumption of goods, and it commonly included income-producing activities
both inside and outside the home, in the highly industrialized early-twentieth-century United States, however, overproduction rather than scarcity was becoming a problem Thus, the ideal American homemaker was viewed as a consumer rather than a producer Schools trained women to be consumer homemakers cooking, shopping, decorating, and caring for children "efficiently" in their own homes, or if economic necessity demanded, as employees in the homes of others Subsequent reforms have made these notions seem quite out-of-date

century
B the formal schooling in the United States in the nineteen century
C the urbanization in the United States in the nineteen century

The New York Times is a daily newspaper published in New York city For a long time, it has been
the newspaper of record in the United States and one of the world’s great newspapers Its strength is in its editorial excellence; it has never been the largest newspaper in terms of circulation
The Times was established in 1851 as a penny paper whose editors wanted to report the news in a
restrained and objective fashion It enjoyed early success as its editors set a pattern for the future by
Trang 24appealing to a cultured, intellectual readership instead of a mass audience However, in the late nineteenth century, it came into competition with more popular, colorful, if not lurid, newspapers in New York City Despite price increases, the Times was losing $1,000 a week when Adolph Simon Ochs bought it in 1896.
Ochs built the Times into an internationally respected daily He hired Carr Van Anda as editor Van
Anda placed greater stress than ever on full reporting of the news of the day, and his reporters maintained

a penny In April 1912, the paper took many risks to report every aspect of the sinking of the Titanic This
greatly enhanced its prestige, and in its coverage of two world wars, the Times continued to enhance its
reputation for excellence in world news
In 1971, the Times was given a copy of the so–called “Pentagon Papers,” a secret government study
of U.S involvement in the Vietnam War When it published the report, it became involved in several awsuits The U.S Supreme Court found that the publication was protected by the freedom–of–thepress clause in the First Amendment of the U.S Constitution Later in the 1970s, the paper, under Adolph Ochs’s grandson, Arthur Ochs Sulzberger, introduced sweeping changes in the organization of the newspaper and its staff and brought out a national edition transmitted by satellite to regional printing plants

Exercise 18: Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.
The ideas of John Dewey, philosopher and educator, have influenced American thought for over one hundred years Dewey was born in Vermont in 1859, and throughout his life, he kept the respect for experience, individuality, and fair play that shaped the character of the nineteenth–century Vermonter He viewed his own life as a continuously reconstructive process–with experience and knowledge building to each other
By the 1930s, Dewey had simplified his theory of experience to its essence As the intellectual
leader of the progressive schools, he asserted that there was danger in rejecting the old unless the new was rooted in a correct idea of experience He held that experience is an interaction between what a person already knows and the situation at hand Previous knowledge interacting with the present environment influences future experience
Dewey believed that experience could not be equated with education because all experiences are not necessarily educative Experience is educative only when it contributes to the growth of the individual,
but it can be miseducative if it distorts the growth of future experience It is the quality of experience that
matters Thus, productive experience is both the means and the goal of education Furthermore, since education is a social process, truly progressive education involves the participation of the learner in directing the learning experience
During his long life, Dewey lectured and published prolifically These writings were influential
both during his lifetime and after his death at the age of ninety–two He viewed his whole life as an experiment which would produce knowledge that would lead to the further experimentation The range and diversity of Dewey’s writings and his influence on society place him among American’s great thinkers
Question 110: What does the passage mainly discuss?
A John Dewey’s theory of experience B The educational methods of John Dewey.
C John Dewey’s professional growth D The progressive movement in education.
Question 111: The author implies that Dewey’s Vermont background _.

LEVELS OF VOCABULARY
Most languages have several levels of vocabulary that may be used by the same speakers In English, at least three have been identified and described
Standard usage includes those words and expressions understood, used, and accepted by a majority
of the speakers of a language in any situation regardless of the level of formality As such, these words and expressions are well defined and listed in standard dictionaries Colloquialisms, on the other hand, are familiar words and idioms that are understood by almost all speakers of a language and used in informal speech or writing, but not considered acceptable for more formal situations Almost all idiomatic expressions are colloquial language Slang, refers to words and expressions understood by a large number
of speakers but not accepted as appropriate formal usage by the majority
Colloquial expressions and even slang may be found in standard dictionaries but will be so identified Both colloquial usage and slang are more common in speech than writing Colloquial speech often passes into standard speech Some slang also passes into standard speech, but other slang
Trang 27expressions enjoy momentary popularity followed by obscurity In some cases, the majority never accepts
certain slang phrases but nevertheless retains them in their collective memories Every generation seems
to require its own set of words to describe familiar objects and events
It has been pointed out by a number of linguists that three cultural conditions are necessary for the creation of a large body of slang expressions First, the introduction and acceptance of new objects and situations in the society; second, a diverse population with a large number of subgroups; third, association among the subgroups and the majority population
Finally, it is worth noting that the terms “standard”, “colloquial”, and “slang” exist only as abstract labels for scholars who study language Only a tiny number of the speakers of any language will be aware that they are using colloquial or slang expressions Most speakers of English will, during appropriate situations, select and use three types of expressions
Question 118: Which of the following is the main topic of the passage?
C Different types of vocabulary D Dictionary usage.
Question 119: How is slang defined by the author?
A Words and phrases accepted by the majority of formal usage.
B Words or phrases understood by the majority but not found in standard dictionaries.
C Words or phrases that are understood by a restricted group of speakers.
D Words or phrases understood by a large number of speakers but not accepted as formal usage.
Question 120: The word “appropriate” in paragraph 2 is closest in meaning to _.
Question 121: The word “them” in paragraph 3 refers to _.
Question 122: What does the author mean by the statement in paragraph 2: “Colloquialisms, on the other
hand, are familiar words and idioms that are understood by almost all speakers of a language and used
in informal speech or writing, but not considered acceptable for more formal situations.”?
A Familiar words and phrases are found in both speech and writing in formal settings.
B Familiar situations that are experienced by most people are called colloquialisms.
C Informal language contains colloquialisms, which are not found in more formal language.
D Most of the speakers of a language can used both formal and informal speech in their appropriate

Trang 28In addition to the great ridges and volcanic chains, the oceans conceal another form of undersea
mountains: the strange guyot, or flat-topped seamount No marine geologist even suspected the existence
of these isolated mountains until they were discovered by geologist Harry H Hess in 1946
He was serving at the time as naval officer on a ship equipped with a fathometer Hess named these truncated peaks for the nineteenth-century Swiss-born geologist Arnold Guyot, who had served on the faculty of Princeton University for thirty years Since then, hundreds of guyots have been discovered in every ocean but the Arctic Like offshore canyons, guyots present a challenge to oceanographic theory They are believed to be extinct volcanoes Their flat tops indicate that they once stood above or just below the surface, where the action of waves leveled off their peaks Yet today, by definition, their summits are at least 600 feet below the surface, and some are as deep as 8,200 feet Most lie between 3,200 feet and 6,500 feet Their tops are not really flat but slope upward to a low pinnacle at the center Dredging from the tops of guyots has recovered basalt and coral rubble, and that would be expected from the eroded tops of what were once islands Some of this material is over 80 million years old Geologists think the drowning of the guyots involved two processes: The great weight of the volcanic mountains depressed the sea floor beneath them, and the level of the sea rose a number of times, especially when the last Ice Age ended, some 8,000 to 11,000 years ago

Our eyes and ears might be called transformers because they send the light and sound around us and
turn them into electrical impulses that the brain can interpret These electrical impulses that have been transformed by the eyes and ears reach the brain and are turned into massages that we can interpret For the eye, the process begins as the eye admits light waves, bends them at the cornea and lens, and then
focuses them on the retina At the back of each eye, nerve fibers bundle together to form optic nerves, which join and then split into optic tracts Some of the fibers cross so that part of the input from the right
visual field goes into the left side of the brain, and vice versa The process in the ear is carried out through sensory cells that are carried in fluid-filled canals and that are extremely sensitive to vibration
Sound that is transformed into electricity travels along nerve fibers in the auditory nerve These fibers form a synapse with neurons that carry the massages to the auditory cortex on each side of the brain
Question 131: According to the author, we might call our eyes and ears "transformers" because _.
A they sense light and sound B the brain can interpret the input

Alzheimer's disease impairs a person's ability to recall memories, both distant and as recent as a
few hours before Although there is not yet a cure for the illness, there may be hope for a cure with a protein called nerve growth factor The protein is produced by nerve cells in the same region of the brain where Alzheimer's occurs Based on this relationship, scientists from the University of Lund in Sweden and the University of California at San Diego designed an experiment to test whether doses of nerve growth factor could reverse the effects of memory loss caused by Alzheimer's Using a group of rats with impaired memory, the scientists gave half of the rats doses of nerve growth factor while giving the other half a blood protein as a placebo, thus creating a control group At the end of the four-week test, the rats given the nerve growth factor performed equally to rats with normal memory abilities While the
experiments do not show that nerve growth factor can stop the general process of deterioration caused
by Alzheimer's, they do show potential as a means to slowing the process significantly.

Exercise 23: Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions
(1) The initial contact between American Indians and European settlers usually involved trade,
whereby Indians acquired tools and firearms and the Europeans obtained furs These initial events usually pitted Indian tribes against each other as they competed for the European trade and for the lands containing fur-producing animals When the furs had been depleted, the Europeans began a campaign to obtain the lands the Indians occupied The Indians often formed confederations and alliances to fight back the Europeans; however, the Indians’ involvement in the white people’s wars usually disrupted these confederations Indians resisted the attempts by the whites to displace them They fought defensive wars such as the Black Hawk War in 1832 Indian uprisings also occurred, like the Sioux uprising in the 1860s
(2) Despite the resistance of the Indians, the Europeans were destined to win the conflict After
Indian resistance was crushed, the whites legitimized the taking of Indian lands by proposing treaties,
frequently offering gifts to Indian chiefs to get them sign the treaties Once an Indian group had signed a treaty, the whites proceeded to remove them from their land Often the Indians were forced west of the Mississippi into Indian Territory-land the whites considered uninhabitable If only a few Indians remained after the conquest, they were often absorbed by local tribes or forced onto reservations
(3) No aspect of American history is more poignant than the accounts of the forced removal of
Indians across the continent As white settlers migrated farther west, Indians were forced to sign new
treaties giving up the lands earlier treaties had promised them Some Indian tribes, realizing the futility of
resistance, accepted their fate and moved westward without force The Winnebagos, who offered little resistance, were shifted from place to place between 1829 and 1866 About half of them perished during
Trang 32their perpetual sojourn Other tribes, however, bitterly resisted The Seminoles signed a treaty in 1832 but violently resisted removal Hostilities broke out in 1835 and continued for seven years The United States government lost nearly 1,500 men and spent over $50 million in its attempts to crush Seminole resistance Most of Seminoles were eventually forced to Indian Territory However, several hundred remained in the Florida Everglades, where their descendants live today

(1) Just as optical fibers have transformed communication, they are also revolutionizing medicine These ultra- thin, flexible fibers have opened a window into the living tissues of the body By inserting optical fibers through natural openings or small incisions and threading them along the body's established
pathways, physicians can look into the lungs, intestines, heart and other areas that were formerly
inaccessible to them
(2) The basic fiber-optics system is called fiberscope, which consists of two bundles of fibers One, the illuminating bundle, carries light to the tissues Is is coupled to a high-intensity light source Light
enters the cores of the high-purity silicon glass and travels along the fibers A lens at the end of the
bundle collects the light and focuses it into the other bundle, the imaging bundle Each fiber in the bundle transmits only a tiny fraction of the total image The reconstructed image can be viewed through an eyepiece or displayed on a television screen During the last five years, improved methods of fabricating optical fibers have led to a reduction in fiberscope diameter and an increase in the number of fibers,
which in turn has increased resolution
(3) Optical fibers can also be used to deliver laser light By use of laser beams, physicians can perform surgery inside the body, sometimes eliminating the need for invasive procedures in which healthy tissue must be cut through to reach the site of disease Many of these procedures do not require anesthesia and can be performed in a physician's office These techniques have reduced the risk and the cost of medical care
Question 157: What is the main topic of the passage?
A A revolution in communication B The invention of optical fibers.
C New surgical techniques D The roles of optical fibers in medicine.
Question 158: Which of the following is closest in meaning to the word “formerly” in paragraph 1?

(1) Over the past 600 years, English has grown from a language of few speakers to become the
dominant language of international communication English as we know it today emerged around 1350,
after having incorporated many elements of French that were introduced following the Norman invasion
of 1066 Until the 1600s, English was, for the most part, spoken only in England and had not extended even as far as two centuries, English began to spread around the globe as a result of exploration, trade
(including slave trade), colonization, and missionary work Thus, small enclaves of English speakers became established and grew in various parts of the world As these communities proliferated, English
gradually became the primary language of international business, banking and diplomacy
(2) Currently, about 80 percent of the information stored on computer systems worldwide is
English Two - thirds of the world’s science writing is in English, and English is the main language of technology, advertising, media, international airports, and air traffic controllers - Today there are more than 700 million English users in the world, and over half of these are nonnative speakers, constituting the largest number of nonnative users than any other language in the world

answer sheet to indicate the correct answer to each of the questions.
(1) Interest is the sum charged for borrowing money for a fixed period of time Principal is the term
used for the money that is borrowed, and the rate of interest is the percent per year of the principal
charged for its use Most of the profits for a bank are derived from the interest that they charge for the use
of their own or their depositor’s money
(2) All problems in interest may be solved by using one general equation that may be stated as follows:
Interest = Principal X Rate X Time (3) Any one of the four quantities – that is, interest, principal, rate, or time – may be found when the other three are known The time is expressed in years The rate is expressed as a decimal fraction Thus, 6 percent interest means six cents charged for the use of $1 of principal borrowed for one year Although
the time may be less than, equal to, or greater than one year, most applications for loans are for periods of
less than one year For purpose of computing interest for short periods, the commercial year or 360 days
is commonly used, but when large sums of money are involved, exact interest is computed on the basis of
365 days

(1) The protozoans, minute, aquatic creatures each of which consists of a single cell of protoplasm,
constitute a classification of the most primitive forms of animal life They are fantastically diverse, but three major groups may be identified on the basis of their motility The Mastigophora have one or more long tails, which they use to project themselves forward The Ciliata, which use the same basic means for locomotion as the Mastigophora, have a larger number of short tails The Sarcodina, which include amoebae, float or row themselves about on their crusted bodies
(2) In addition to their form of movement, several other features discriminate among the three
groups of protozoans For example, at least two nuclei per cell have been identified in the Ciliata, usually
a large nucleus that regulates growth but decomposes during reproduction, and a smaller one that contains the genetic code necessary to generate the large nucleus
(3) Protozoans are considered animals because, unlike pigmented plants to which some protozoans
are otherwise almost identical, they do not live on simple organic compounds Their cell demonstrates all
of the major characteristics of the cells of higher animals
(4) Many species of protozoans collect into colonies, physically connected to each other and
responding uniformly to outside stimulae Current research into this phenomenon, along with
investigations carried out with advanced microscopes may necessitate a redefinition of what constitutes protozoans, even calling into question the basic premise that they have only one cell Nevertheless, with the current data available, almost 40,000 species of protozoans have been identified No doubt, as the technology improves our methods of observation, better models of classification will be proposed
Question 175: Where do protozoans probably live?
Question 176: What is protoplasm?
A A class of protozoan
B The substance that forms the cell of a protozoan
C A primitive animal similar to a protozoan
D An animal that developed from a protozoan
Question 177: To which class of protozoans do the amoebae belong?
Question178: What is the purpose of the large nucleus in the Ciliata?
A It generates the other nucleus.
B It contains the genetic code for the small nucleus.
Trang 38C It regulates growth.
D It reproduces itself.
Question 179: Why are protozoans classified as animals?
A They do not live on simple organic compounds.
B They collect in colonies.
C They respond uniformly to outside stimulate.
D They may have more than one cell.
Question 180: The word “uniformly” in paragraph 4 is closest in meaning to

answer sheet to
indicate the correct answer to each of the questions.
Reading to oneself is a modern activity which was almost unknown to the scholars of the classicaland medieval worlds, while during the fifteenth century the term “reading” undoubtedly meant
readingaloud Only during the nineteenth century did silent reading become commonplace.
One should be wary, however, of assuming that silent reading came about simply because readingaloud was a distraction to others Examinations of factors related to the historical development of silentreading have revealed that it became the usual mode of reading for most adults mainly because the tasksthemselves changed in character
The last century saw a steady gradual increase in literacy and thus in the number of readers As thenumber of readers increased, the number of potential listeners declined and thus there was somereduction in the need to read aloud As reading for the benefit of listeners grew less common, so
came the flourishing of reading as a private activity in such public places as libraries, railway carriages
andoffices, where reading aloud would cause distraction to other readers
Trang 39Towards the end of the century, there was still considerable argument over whether books shouldbe used for information or treated respectfully and over whether the reading of materials such asnewspapers was in some way mentally weakening Indeed, this argument remains with us still ineducation However, whatever its virtues, the old shared literacy culture had gone and was replaced bythe printed mass media
on the one hand and by books and periodicals for a specialised readership onthe other.
By the end of the twentieth century, students were being recommended to adopt attitudes to
booksand to use reading skills which were inappropriate, if not impossible, for the oral reader The
social,cultural and technological changes in the century had greatly altered what the term “reading” implied
Question 183: Reading aloud was more common in the medieval world because
A few people could read to themselves
B there were few places available for private reading
C silent reading had not been discovered
D people relied on reading for entertainment
Question 184: The word “commonplace” in the first paragraph mostly means “ ”.
A attracting attention B for everybody’s use C most preferable D widely used
Question 185: The development of silent reading during the last century indicated
A an increase in the number of books B an increase in the average age of readers
C a change in the status of literate people D a change in the nature of reading
Question 186: Silent reading, especially in public places, flourished mainly because of
A the decreasing need to read aloud B the development of libraries
C the increase in literacy D the decreasing number of listeners
Question 187: It can be inferred that the emergence of the mass media and specialised reading materials
was an indication of
A a decline of standards of literacy B a change in the readers’ interest
C an improvement of printing techniques D an alteration in educationalists’ attitudes

The Sun today is a yellow dwarf star It is fueled by thermonuclear reactions near its center that convert hydrogen to helium The Sun has existed in its present state for about four billion six hundred million years and is thousands of times larger than the Earth
Trang 40By studying other stars, astronomers can predict what the rest of the Sun’s life will be like About five billion years from now, the core of the Sun will shrink and become hotter The surface temperature will fall The higher temperature of the center will increase the rate of thermonuclear reactions The outer regions of the Sun will expand approximately 35 million miles, about the distance to Mercury, which is the closest planet to the Sun The Sun will then be a red giant star Temperatures on the Earth will become too high for life to exist
Once the Sun has used up its thermonuclear energy as a red giant, it will begin to shrink After it shrinks to the size of the Earth, it will become a white dwarf star The Sun may throw off huge amounts
of gases in violent eruptions called nova explosions as it changes from a red giant to a white dwarf
After billions of years as a white dwarf, the Sun will have used up all its fuel and will have lost its heat Such a star is called a black dwarf After the Sun has become a black dwarf, the Earth will be dark
and cold If any atmosphere remains there, it will have frozen over the Earth’s surface
