Lasik surgery is a new method of restoring certain kinds of vision loss

Lasik is an acronym derived from the word “laser” and some medical

terms

Unlike cataract surgery, which restores vision to eyes marred by a cloudy

lens, Lasik is an elective procedure performed on healthy eyes

Gener-ally, patients who choose Lasik surgery suffer from myopia, or

nearsight-edness, which means that their eyes cannot visualize distant objects It

also corrects farsightedness, the inability to see close objects, as well as

astigmatism, which is a visual distortion that causes blurred vision But

the procedure does not correct presbyopia, the inability of the eye to

focus that comes naturally with age

Lasik Surgery

Lasik surgery is painless Recovery is fast, and vision stabilizes quickly Also, it is easy to go back to fine-tune results Using a special knife, the surgeon slices a microscopically-thin hinged flap in the top of the cornea, exposes what is under the flap, and then zaps the exposed tissue with a laser for a preprogrammed number of seconds The laser sculpts the cornea according to the correction needed The flap is then carefully replaced The eye’s natural suction enables the flap to adhere without stitches

Generally, Lasik is not appropriate for patients with high levels of nearsightedness or astigmatism It is also possible that patients with large pupils will experience glare and halos after surgery Likewise, some patients have been left with serious and uncorrectable problems after the procedure, including glare, haze, double vision, ghosting, or irregular astigmatism, a permanent warping of the cornea

Preparing for the Listening Section

As I say many times in this book, the best way to improve your English is to listen

to as much English as possible Use the following tips to listen to English daily:

■ Watch movies and television, including news programs and weather reports If a television isn’t available, listen to the radio

■ Make telephone calls to recorded messages For example, some news-papers have recorded information about local events and most movie theaters have recorded schedules of showings

■ Attend lectures in English if you can

■ Make use of a language laboratory if one is available Check with a local university that has an intensive English program or with a Sylvan

Learning Center in your area

24

■ Listen to books on tape If you live in the United States, check out the tape

program at Cracker Barrel restaurants, where you can exchange books on

tape for a $1 rental charge I prefer listening to unabridged books

(mean-ing those with noth(mean-ing omitted), so I get books on tape from Recorded

Books, Inc (www.recordedbooks.com) This company has a wide variety

of books available for sale or rent

■ Take all the listening practice tests in this book If you can obtain the

TOEFL Sampler materials available, use them as well

STRUCTURE SECTION

The Structure section of the TOEFL test measures your ability to recognize appro-priate standard written English This section includes questions that test your knowledge of grammar, idiomatic expressions, vocabulary, and other aspects of correct English

The Structure section includes two question types (described in this chapter), which are interspersed You will answer between 20 and 25 questions in 15 to 20 minutes The time that you are given to complete the section depends on the num-ber of questions given You cannot know in advance how many questions to ex-pect in this section When you begin the section, the number of questions you must answer and the time allotted for completing them will appear at the top of the screen

Basic Skills Necessary

To score well on this section, you need to know standard English grammar You must be able to recognize various parts of speech and identify when they are used incorrectly in a test question You must know when a sentence is missing a word

or phrase that is necessary for the construction to be complete And you must have

a solid enough understanding of idiomatic expressions to recognize when words are being combined incorrectly I cover each of these areas in detail in Part III

What to Expect

There are two types of questions in the Structure section One type of question shows a sentence with four words or phrases underlined You must choose the one underlined word or phrase that is incorrect and click on it The other type of ques-tion consists of an incomplete sentence with four choices of words or phrases that complete it You must choose the one word or phrase that creates a correct sentence With both types of questions, you must concentrate on whether or not a sentence

is complete After you answer a question (and before you move on to the next one), always analyze whether the sentence as a whole is complete with the correc-tion or answer choice that you have selected If you create a sentence fragment, your answer choice is incorrect

To improve your knowledge of grammar, read as much as possible, paying atten-tion to grammar forms that are new to you Read newspapers, magazines, and books Any topic that interests you will suffice The more complicated the subject matter, the better, but don’t become discouraged by trying to read advanced maga-zines or complicated newspaper articles that are too far above your level

26

Listening to books on tape is also a great way to improve your grammar (as well

as your listening comprehension) if you can pay attention to the structure of

sen-tences while also following the story

Incomplete Sentences

Directions: You will be shown incomplete sentences with a blank indicating

where a word or phrase needs to be added Choose the word or phrase that most

correctly completes the sentence

Sample

Q While it is understandable that a going business with existing customers and

name recognition will be purchased by another company, it is surprising that

companies would purchase an internet domain name in

busi-ness for an incredible sum of money

A that it has never been used

B. that has never been used

C that never been used

D never to be use

A is incorrect because it contains the pronoun it, but the word that is a relative

pronoun C is incorrect because you cannot have a past participle of be (been)

without an auxiliary has D is incorrect because the word use is not in past

partici-ple form Therefore, the correct answer is B.

Choosing the Incorrect Word or Phrase

Directions: You will see sentences with four underlined words or phrases.

Choose the one word or phrase that is incorrect in standard written English

Sample

Q After create [A] interest in automobile racing on the hard-packed sand of the

beach in Daytona Beach Florida, William France, Sr built [B] the Daytona

International Speedway on property leased [C] from the county and lived to

see it develop [D] into a major international attraction.

The answer is A, create The sentence should read After having created, After he

had created, or After creating A verb in simple form cannot follow a preposition.

Only a gerund (verb+ing) or a clause (subject +verb) can follow a preposition

How to Prepare for the Structure Section

To improve your knowledge of grammar, read as much as possible, paying atten-tion to grammar forms that are new to you Follow these tips:

■ Read newspapers, magazines, and books

■ Listen to books on tape, paying attention to sentence structures

■ Go through all the grammar rules in Part III of this book and become thor-oughly familiar with them

READING SECTION

The Reading section measures your ability to read and understand academic

read-ing passages, includread-ing your knowledge of English vocabulary

Basic Skills Necessary

To succeed in this section, you need to be able to read and understand English

You should have a sufficient knowledge of vocabulary and grammar to follow a

fairly sophisticated passage, understand the difference between major ideas and

details, and discern vocabulary definitions

What to Expect

Reading section questions are based on major topics, subtopics, and details

pre-sented in a reading passage Approximately 20 percent of the questions in this

sec-tion are vocabulary quessec-tions, and all vocabulary words are contained in the

reading passages

Several question types exist in this section You may be asked to pick out a correct

answer from four possible choices, or you may be asked to click on a word in a

passage that has the same meaning as another word In addition, the Reading

sec-tion frequently tests your understanding of pronouns and their antecedents

Sometimes four possible choices are provided, and sometimes you’re asked to

click on the word in the passage that is the antecedent of the pronoun in question

Occasionally, you’re required to identify the most logical place to insert a new

sentence into a paragraph in the reading

Sometimes you’re asked to choose a correct picture, word, phrase or diagram

based on what the passage describes Sometimes you also need to match pictures,

words, phrases, or diagrams with other items similar to them (However, there

were no questions like this on a recent TOEFL test administration.) For example,

you might be given the word blue and asked whether the word color, shape, or

size best describes that word.

The quality of the passages in the Reading section may surprise you They rarely

consist of more than a couple of paragraphs, and generally, they don’t have formal

introductions and conclusions

Concentrate on the topic sentence of each paragraph and read the entire passage,

but don’t spend too much time trying to understand it Read the passage quickly
