adjective clause No commas are used around necessary adjective clauses
Of all living things, the chimpanzee has a genetic make-up that is most similar to ours
When an adjective clause gives extra information and is not necessary to identify the noun,
commas are placed around the adjective clause Commas are a clue that can help you recognize
some adjective clauses
Elizabeth Cady Stanton, who was born in Johnstown, New York, was an early
American feminist
Note: When commas are used around an adjective clause, that cannot begin the clause

There are social situations where people who give information are higher in status
than those who need information
(Answers: The adjective clause where people who give information are higher in status than
those who need information modifies the noun situations The adjective clause who give
information modifies the noun people The adjective clause who need information modifies
the pronoun those.)
Some adjective clauses can be reduced to adjective phrases, with no change in meaning An
adjective clause can be reduced to an adjective phrase only when the clause has who, which,
or that as its subject
Adjective Clause:
The general who had led the Union Army to victory was Ulysses S Grant
Adjective Phrase:
The general leading the Union Army to victory was Ulysses S Grant
Adjective Clause:
A proton is one of two kinds of particles that make vp the nucleus of an atom
Adjective Phrase:

S~« omit the subject of the clause (the relative pronoun)
*~a omit the auxiliary verbs, if there are any
“ss change the verb to its ing form
DELTA'2 KEy To THE TOEFL® Tesr 213
Trang 2
Note: Use the —ing form (present participle) when the adjective phrase is in the active voice Use
the ~ed form (past participle) when the adjective phrase is in the passive voice (See 2.6)
These rules apply to verbs in any tense
Active Voice:
The technology that impacts us most is what we use in our homes
The technology impacting us most is what we use in our homes
Passive Voice:
Yellowstone, which was authorized by Congress in 1872, is the oldest national
park in the United States
Yellowstone, authorized by Congress in 1872, is the oldest national park in
the United States
Note: If the adjective clause needs commas, the adjective phrase also needs commas:
Crater Lake, which was formed by a volcano, is a superb setting for day hikes
Crater Lake, formed by a volcano, is a superb setting for day hikes
6 Some adjective clauses can be reduced to appositive phrases An appositive is a noun phrase that
is placed near another noun to define or explain it (See 2.2) Appositives do not have verbs
Adjective Clause:
One application of the laser is holography, which is the production of three- dimensional images
Appositive Phrase:
One application of the laser is holography, the production of three-dimensional images

“~« no adjective clause where one is needed
®+ an incomplete adjective clause
&~¢ an incorrect relative pronoun
“s no preposition where one is needed before a relative pronoun
an incorrect participle in an adjective phrase
8 A TOEFL item may test your ability to recognize when an adjective clause is needed Look at this
example:
The fat-soluble vitamins are stored in body fat and may therefore accumulate in quantities -
C can be toxic
C Ð that can be toxic
C 3 they can be toxic
C) can they be toxic
All of the answer choices contain a verb Therefore, you know that the missing part of the sen-
tence must be an adjective clause that will modify the noun quantities

11,
Only the second choice, that can be toxic, has the correct form and necessary parts of an adjective
clause: subject (relative pronoun) + verb The other three choices are incorrect because they either
lack a relative pronoun or have incorrect word order
A test item may try to trick you by having an incorrect relative pronoun Look at this example:
Benefits of a credit account, what may change from time to time, typically
include certain kinds of insurance coverage
Which underlined word or phrase must be changed for the sentence to be correct? If you chose
what, you were correct because what makes a noun clause (See 2.9), not an adjective clause
Correction: which
Some of the answer choices may test you by not having a preposition where one is needed before
the relative pronoun Look at this example:
For today’s astronomers, constellations are simply areas of the sky
an interesting objects await observation
C3 in that C) which C) in which C) are
Interesting objects await observation in areas of the sky A preposition is needed before the rela-
tive pronoun to communicate this location The third answer choice, in which, best completes the
sentence, which should read: For todays astronomers, constellations are simply areas of the sky
in which interesting objects await observation

Why are the other three answer choices incorrect?
A TOEFL item may test your ability to recognize the correct participle in an adjective phrase
Look at this example:
Bobsleds, - by two— or four-man crews, have a metal brake with
several teeth
C3 driven
are driven
C 3 they are driven
C 3 đrivíng
The commas are a clue that the missing part of the sentence is the beginning of an adjective
clause or phrase to modify bobsleds Because the answer choices contain a participle but not a
relative pronoun, you know the correct answer is an adjective phrase
You can see that by two- or four—man crews indicates passive voice (See 2.6) The first answer
choice, driven, best completes the sentence because it is the past participle, which passive voice
requires
Why are the other three answer choices incorrect?

Look at another example:
A great amount of unemployment is the simple turnover of people either -
for the first time or reentering it
enter the labor force
= entered the labor force
€ 3 are entering the labor force C.) entering the labor force
In this sentence, people needs an active voice verb because people are doing the action; they are
entering or reentering the labor force Therefore, you must use the present participle The fourth
choice, entering the labor force, best completes the sentence

usage among economists, the term “natural rate” is misleading
Now, read another TOEFL item What does this sentence need?
Jack McAuliffe had been the undefeated amateur boxing champion
oe the professional champion in 1885
and becoming before becoming became
This sentence needs a subordinate clause after the main clause, Jack McAuliffe had been the
undefeated amateur boxing champion Notice, however, that none of the answer choices has
a subject! How can one of them be a clause?
Like adjective clauses (See 2.10), some adverb clauses can be reduced to phrases The answer is
the second choice, before becoming, which is an adverb phrase that has been reduced from the
adverb clause before he became

At least one item on the TOEFL will test your ability to recognize correct usage of adverb clauses
and phrases
An adverb clause modifies a main clause or the verb in a main clause Like all subordinate claus-
es, an adverb clause must have a subject and a verb An adverb clause cannot stand alone as a
sentence It must be connected to a main clause to make a complete sentence
Adverb clauses begin with words called subordinators or subordinating conjunctions
Martin Luther King was such a powerful orator that his speeches continue to inspire people many years afterward
Even though it appears to help some people, doctors disagree on melatonin’s safety
The raccoon rubs and tears its food underwater, as if the food needed washing
Note: Sentences with adverb clauses of condition are called conditional sentences (You will
review conditional sentences in 2.12.) The order of the adverb clause and the main clause can be reversed without a change in meaning
These two sentences have the same meaning:
Malcolm X had been assassinated by the time his autobiography was published
By the time his autobiography was published, Malcolm X had been assassinated
Note: When the adverb clause comes first, it is followed by a comma
Some adverb clauses can be reduced to adverb phrases, with no change in meaning An adverb
clause can be reduced to an adverb phrase only when the subject of the adverb clause is the same
as the subject of the main clause
Adverb clauses that begin with after, before, since, when, and while are frequently reduced to
phrases
