few
B – GENERAL QUANTITY EXPRESSIONS WITH NONCOUNT NOUNS: a great deal of,
much, a little, little
C – GENERAL QUANTITY EXPRESSIONS WITH COUNT NOUNS AND NONCOUNT NOUNS: a lot of = lots of, plenty of, some, any, no
MANY vs MUCH: Use MANY in affirmative, negative statements and questions Use
MUCH in negative statements and questions MUCH is not usually used alone in affirmative statements Use A LOT OF instead
For example:
1 I have many friends / I don’t have many friends./ Do you have many friends?
2 We don’t get much rain here / Do you get much rain here? / We get a lot of rain here.
Trang 2 A FEW/FEW vs A LITTLE/ LITTLE:
+ A FEW and A LITTLE give a positive idea; they indicate that something exists, is present + FEW and LITTLE give a negative idea; they indicate that something is largely absent.
Expressing NONE: Use NO, NOT ANY to express NONE NO is used in affirmative
statements, but it has a negative meaning NOT ANY is used to form a negative statement
For example: 1 There is no sugar in this dessert ( There isn’t any sugar in this dessert.)
3 There are no eggs in this recipe ( There aren’t any eggs in this recipe.)
Emphasizing Amounts:
+ Use TOO and SO before MANY/MUCH to emphasize a larger amount TOO usually has a
negative meaning

2 There are too many choices on this menu I can’t decide what to eat.
3 She’s made so much money this year She’s happy about it.
4 She’s made too much money this year She’ll have to pay a lot in taxes + Use ONLY before A FEW or A LITTLE to emphasize an even smaller amount Use QUITE with A FEW (not A LITTLE) to emphasize a larger amount.
For example: 1 Only a few houses are available (There are a small number of houses.)
2 Quite a few houses are available (There are a large number of houses.)
3 Would you like some milk in your coffee? Only a little, please.

GRAMMAR: CHAPTER 13 INDEFINITE AND DEFINITE ARTICLES
INDEFINITE ARTICLES: A, AN, SOME introducing a Noun
Use A/AN to introduce a singular count noun THERE IS/THERE ARE often begins a sentence
or clause that introduces a noun with an indefinite article
For example:
Woman: Did you see a little boy walk by here five minutes ago.
Police officer: I’m not sure What does he look like?
Woman: He has brown hair, and there’s a big soccer ball on his sweatshirt.
Use SOME or no article to introduce plural count nouns or noncount nouns.
For example:
I need some batteries for my camera.( I need batteries for my camera.)
I called for some information (I called for information.)
When a speaker uses an indefinite article, the noun is not a specific thing in the mind of the listener In the speaker’s mind, however, sometimes the noun is specific and sometimes it is not
For example:
Bob: I bought a new car (Bob has a specific car in mind, but the listener doesn’t.)
Bob: I need a new car (Neither Bob nor the listener have a specific car in mind.)
DEFINITE ARTICLE: THE identifying a Noun
(Use THE to refer to a noun that both you and a listener can identify This is possible when you and the listener share information about the noun.)
Use the definite article THE after a noun has already been introduced or mentioned
For example: 1 I bought Koji a sweater and a watch for his birthday However, the sweater
doesn’t fit and the watch doesn’t work!
Use the definite article THE for objects that you can see or hear
For example: 1 Could you pass the butter, please?
2 That must be a big fire I can hear the sirens from here!
Use the definite article THE when you and a listener share general knowledge about something in your environment
For example: A: Oh, no! The copy machine is broken again!
B: I can’t believe it!
Trang 4 Use the definite article when other information in the sentence identifies the noun.
For example: 1 Turn off the light near the door.
2 Please hand me the book about England.
Use the definite article with certain nouns (store, doctor, hospital, movies, bank, park, TV, telephone) that are familiar to you and a listener in everyday life
For example: 1 A: I’m going to the doctor this morning Can I borrow your car?
B: Sure.
2 A: Hello I’m here to see Ms Stephens.
B: I’m sorry, she’s on the telephone Would you like to sit down and wait?
Use the definite article for a noun that is unique (the only one)
For example: 1 The earth revolves around the sun.
2 Tokyo is the capital of Japan.
NOUNS IN GENERAL STATEMENTS
* Making General Statements:
Sometimes a noun is used to make a general statement about a whole class or group These nouns do not identify a specific person, place, or thing They represent all members of that class or group
For example: 1 Ants are insects / 2 Chocolate is made from cacao seeds.
When making general statements about a whole class or group, we use A/AN with singular count nouns, and no articles with plural count nouns and noncount nouns
For example: 1 A cheetah can run very fast (singular count noun)
2 Cheetahs can run very fast (Plural count noun)
3 Oxygen is necessary for our survival (Noncount noun)
THE is sometimes used before singular count nouns in more formal discussions about plants, animals, and machines Musical instruments usually occur with THE in general statements.
For example: 1 The giant panda is an endangered animal.
2 It’s difficult to play the violin.
General statements are often used to classify and define nouns
For example: 1 A diary is daily record of a person’s life.
2 A carnivorous plant is a plant that eats meat.
General statements are also often used to express opinions
For example: Sharks are beautiful creatures.
Trang 5GRAMMAR: CHAPTER 14
ADJECTIVES
ORDER OF ADJECTIVES:
Adjectives can describe many different features of a noun
Quality/Opinion: comfortable, colorful Color: blue, gray
Age: old, antique, young Material: wooden, cotton
Shape: round, square Kind/Purpose: riding, rocking
If two or more adjectives come before a noun, they usually follow this order: quality/opinion, size, age, shape, color, origin, material, and kind/purpose
For example: 1 That’s an Italian racing bike.
2 They have a beautiful new rocking chair.
We do not usually use more than three adjectives before a noun It is more common to use two or three adjectives and then add other descriptive phrases to the end of the sentence
For example: I bought expensive black leather boots from Italy.
ADJECTIVES ENDING IN –ing / - ed
Adjectives ending in –ING / -ED refer to emotions or feelings The –ING adjective describes a noun that causes an emotion or feeling The –ED adjective describes a noun (usually a person) that feels or experiences an emotion or feeling
For example:
1 It’s an exciting match The excited fans cheered wildly.
2 We heard a frightening scream The frightened child cried all night.
NOTE:
+ Adjectives can occur alone following stative verbs such as BE, BECOME, FEEL, SEEM, LOOK, APPEAR
+ Some adjectives can’t come before a noun (GLAD, PLEASED and certain adjectives beginning with the letter A – awake, alone, asleep, afraid and alike.)
+ Some adjectives can ONLY come before a noun (MAIN, CHIEF, PRINCIPAL, SAME, ONLY, FUTURE, FORMER, PREVIOUS)
Trang 6GRAMMAR: CHAPTER 14
ADVERBS
Adverbs modify or change the meaning of verbs Many adverbs are formed by adding – ly
(quickly, difinitely, unfortunately, unluckily…) Adverbs can occur in different positions in
a sentence, but they never occur between a verb and its object.
+ Adverbs of manner usually come after the verb In sentences with any auxilliary except do (be, have, or a modal verb), -ly adverbs of manner can also be placed between the auxilliary and the
verb Adverbs of manner answer the question HOW? They describe the way someone does something or the way something happens
For example:
1 He works carefully.
2 It snows heavily in Alaska.
3 She has unexpectedly quit her job.
4 You should carefully consider your options.
5 They are quietly waiting for news.
ADVERBS OF POSSIBILITY:
+ Adverbs of possibility show how sure or unsure we are about something
More sure definitely, certainly We are definitely going to win this game
probably If I can find a ride, I’ll probably go.
Less sure maybe, perhaps Perhaps you should stay home
+ Adverbs of time can come at the beginning or end of a sentence They include yesterday, now, today, recently, soon, answer the question WHEN? They can refer to a specific time or a more
indefinite time
For example: 1 She saw him yesterday.
2 I saw him recently.
+ Recently can also occur before the verb or between the auxilliary and the verb.
For example: I recently found a new job / I have recently found a new job.
ADVERBS OF OPINION:
+ Most adverbs of opinion can occur at the beginning or end of a sentence or before the verb They
include fortunately, happily, luckily, incredibly, obviously, strangely, surprisingly, give an opinion
about an entire sentence or idea
For example: 1 It obviously rained last night The ground is still wet.
2 The plane had to make an emergency landing Surprisingly, no one was hurt.
Trang 7 ADVERBS WITH TWO FORMS: Some adverbs, such as hard, high, and late, have two
forms with two meanings
For example: 1 I want to pass this course I’m studying hard (hard = a lot of effort)
2 I don’t care about passing this course I hardly study (hardly = almost not at all)
3 After the storm the snow was piled high (high = to a great height)
4 He is highly respected writer (highly = to a great degree)
5 He arrived at the party late (late = not on time)
6 He hasn’t gone to any parties lately (lately = recently)
+ Use adverbs of degree before adjectives and other adverbs to make them stronger or weaker EXTREMELY, QUITE, REALLY, VERY make adjectives and adverbs STRONGER FAIRLY, PRETTY, SOMEWHAT make adjectives and adverbs weaker
For example: 1 I did very well on the test I got an A.
2 He was extremely upset about the situation I’ve never heard him yell before.
3 She was somewhat upset at first Later she calmed down.
+ SO/SUCH……… + THAT clause: to strengthen adjectives, adverbs, and nouns that are modified by adjectives SO / SUCH can express the reason why something happens The THAT clause expresses the result
For example: 1 The necklace was so beautiful that I had to buy it.
2 It was such a beautiful necklace that I had to buy it
CONTRASTING “TOO”, “ENOUGH”: “Too” ( to an undesirable degree) comes before an adjective or adverb to express a negative meaning “ENOUGH” (to an
acceptable or sufficient degree) follows an adjective or adverb to express a positive
meaning
For example: 1 It’s too hot to eat outside.
2 He works too slowly to finish on time.
3 You aren’t strong enough to pick this up.
4 I jog often enough to stay fit.
5 She didn’t play well enough to make the team She was disappointed.

Trang 9 MAKING COMPARATIONS:
Talking about differences:
+ Use comparatives with adjectives, adverbs, and nouns to talk about differences between two things (people, objects, ideas, places, or actions.)
For example:
1 My father is older than my mother.
2 The new computer runs more smoothly than the old one.
3 There are more cars than buses on the highways.
+ Use the comparative without THAN when the meaning is clear from the context.
For example: She’s a good student, but I think he’s smarter ( = smarter than she is.)
We sang well, but they sang better.
Expressing Greater and Lesser degrees:
+ Use MORE / - ER … THAN shows a larger quantity, degree, or size than something else Use LESS… THAN shows that something is smaller quantity, degree, or size than something else
For example: More / -er …than Less… than
Diamonds are more expensive than rubies Rubies are less expensive than diamonds.
He works more quickly than she does She works less quickly than he does.
+ Use MORE + count or noncount nouns to talk about larger quantities Use FEWER + count
nouns and LESS + noncount nouns to talk about smaller quantities
Mexico City has more people than Seattle The Smiths have more money than the Johnsons Seattle has fewer people than Mexico City The Johnsons have less money than the Smiths.
Changing Situations:
+ A comparative form can be repeated and joined with AND to show that a situation is changing This use of the comparative is common with the verbs of change such as GET, BECOME, and GROW, especially in the present continuous
For example:
1 He looks older and older everyday.
2 I have less and less time to study.
3 Taxes are getting higher and higher.
4 Car engines are becoming more and more efficient.
Trang 10 EQUAL COMPARATION: AS…AS with Adjectives, Adverbs, and Nouns:
AS…AS to talk about similar or equal things:
+ Use AS…AS with adjectives, adverbs, and nouns to say that two things are equal or similar
For example: 1 My office is as big as his office.
2 The student explained the problem as simply as the teacher.
3 We saved as much money as Gina did.
4 They have as many friends as us
+ Use ALMOST, ABOUT, NEARLY before AS…AS to say that two things are close but not quite equal
For example: 1 My office is almost as big as his office.
2 Elena is nearly as tall as Eva.
+ You can omit the second part of an AS…AS phrase when the meaning is clear from the context
For example: 1 Yes, she’s a good student, but he’s as good (= as good as she is.)
NEGATIVE STATEMENTS WITH AS…AS to talk about differences:
+ Use negative statements with AS…AS to talk about differences between two things A negative statement with AS…AS has the same meaning as a comparative sentence with LESS
or FEWER
For example:
1 Ken is not as athletic as Tom ( = Ken is less athletic than Tom.)
2 He didn’t finish as quickly as us (= He finished less quickly than us.)
3 I don’t have as much energy as they do (= I have less energy than they do.)
4 He doesn’t know as many students as I do (= He knows fewer students than I do.)
