The painting was very expensive Ms Wallace bought it The painting that Ms Wallace bought was very expensive
The adjective clause marker in the joined sentence replaces it, the object of the verb bought In the joined sentence, the adjective clause keeps the subject—Ms
Wallace—that it had in the original sentence Notice that the inclusion of the pro- noun itin the joined sentences above would be an error INCORRECT: The painting that Ms Wallace bought it was very expensive
Trang 2In some adjective clauses, the relative pronoun that may be used in place of which or who These sentences are called identifying adjective clauses (also called restrictive adjective clauses) The information in the clause is needed to identify the noun This type of clause is not set off by commas
The island that we visited was beautiful
The people that moved next door are very friendly
In other adjective clauses (called non-identifying or non-restrictive), the clause provides “extra” information It’s not needed to identify the head noun These clauses are always set off with commas
Maui, which is one of the Hawaiian Islands, is quite beautiful The Smiths, who are our new neighbors, are very friendly The word that cannot be used to introduce this type of clause
INCORRECT: Maui, that is one of the Hawaiian Islands, is quite beautiful INCORRECT: The Smiths, that are our new neighbors, are very friendly The adjective clause markers which and whom can also be used as objects of prepositions:
That is the topic I will write on it That is the topic on which I will write
Marie is the student The teacher gave the special assignment to her Marie is the student to whom the teacher gave the special assignment You may also see sentences with adjective clauses used in this pattern:

GRAMMAR POINT 3: ADVERB CLAUSES
An adverb clause consists of a connecting word, called an adverb-clause marker (also called a subordinate conjunction) and at least a subject and a verb
The demand for economical cars increases when gasoline becomes more expensive
In this example, the adverb-clause marker when joins the adverb clause to the main clause The adverb clause contains a subject (gasoline) and a verb (becomes)
An adverb clause can precede the main clause or follow it When the adverb clause comes first, it is separated from the main clause by a comma
When gasoline becomes more expensive, the demand for economical cars increases Adverb Clause

When the subject of the main clause and the subject of the adverb clause are the same person or thing, the adverb clause can be reduced (shortened) Reduced adverb clauses do not contain a verb or a subject They consist of a marker and either a present or past participle If the verb in the full adverb clause is active, the present participle is used If the verb in the full adverb clause is passive, a past par- ticiple is used

When orbiting the earth, astronauts don't feel the force of gravity (reduced clause with present participle)
Although it had been damaged, the machine was still operational (full adverb clause with a passive verb)
Although damaged, the machine was still operational (reduced clause with a past participle)
You will most often see reduced adverb clauses with the markers although, while, if, when, before, after, and until Reduced adverb clauses are NEVER used after because
Don't use because in the expression reason because Use reason that

Adverb Endings
Trang 9The most common type of word form problem involves the use of an adverb in place of an adjective or an adjective in place of an adverb A few points to keep in mind:
» Adjectives modify nouns, noun phrases, gerunds, and pronouns Hang up your wet clothes (adjective modifying the noun clothes)
The two children were kind (adjective modifying the noun phrase the two children)
We saw some wonderful acting in the play (adjective modifying the gerund acting)
They were very brave (adjective modifying the pronoun they) ¢ Adjectives often come before words they modify
an importanttest aquietevening a longarticle
e Adjectives may also follow the verb fo be and other linking verbs The glass was empty
That song sounds nice They look upset
¢ They often answer the question What kind?
She is a brilliant scholar (What kind of a scholar is she? A brilliant one ) > Adverbs modify many types of words, including verbs, participles, adjectives,
and other adverbs
Ann eagerly accepted the challenge (adverb modifying the verb accepted) It was a rapidly changing situation (adverb modifying the present participle changing)
She wore a brightly colored scarf (adverb modifying the past participle colored) Ted seemed extremely curious about that topic (adverb modifying the adjective curious) The accident occurred incredibly quickly (adverb modifying the adverb quickly) G2 = =>) = P2 lớn)
¢ Sometimes adverbs are used at the beginning of sentences, usually fol- lowed by a comma These adverbs modify the entire sentence rather than one word in the sentence
Generally, I like my classes
Usually Professor Fowles’s lectures are more interesting than the one he gave today
¢ Adverbs of manner are formed by adding the suffix -ly to an adjective (or -ally if the adjective ends with the letter -c)
quick quickly comic comically
comfortable comfortably historic historically e Adverbs of manner answer the question How?
Trang 10e A few adverbs (fast, hard, and high, for example) have the same form as adjectives
Charles bought a fast car (adjective)
He was driving so fast that he got a speeding ticket (adverb) ¢ Wellis the irregular adverb form of the adjective good
Juan is an exceptionally good student He did very well on the last test
Besides adjective/adverb problems, there are many other word form problems Some examples are given here:
Corn played an important role in the cultural of the Indians of the Southwest
(The noun culture, not the adjective cultural, is needed.)
The galaxy Andromeda is the most distance object visible to observers in the Northern Hemisphere
(The adjective distant is needed in place of the noun distance.)
Scientists belief that the continents once formed a single continent sur- rounded by an enormous sea
(The verb believe is needed in place of the noun belief.) Bunsen burners are used to hot materials in a chemistry lab (The adjective hot is used incorrectly in place of the verb heat.)
