Skill 6 :
Adverb Clause Connector
Sentences with adverb clauses have
two basic patterns in English. Study the clauses and connectors in the
following sentences:
He is tired because he has
been working so hard.
Because he has been working so hard, he is tired.
In each of these examples, there are
two clauses: he is tired and he has been working so hard.
The clause he has been working so hard is an adverb clause that is introduced with the connector because. In
the first example, the connector because comes in the middle of the sentence,
and no comma (,) is used. In the second example, the connector because comes at
the beginning of the sentence. In this pattern, when the connector comes at the
beginning of the sentence, a comma (,) is required in the middle of the
sentence.
The following example shows how this
sentence pattern could be tested in the Structure section of the TOEFL test.
Example
_____ arrived at the library, he started to work immediately.
(A) The student
(B) When
(C) He
(D) After the student
In this example, you should
recognize easily that the verb arrived needs a subject. There is also another
clause, he started to work immediately. If you choose answer (A) or answer (C),
you will have a subject for the verb arrived, but you will not have a connector
to join the two clauses. Because you need a connector to join two clauses,
answers (A) and (C) are incorrect. Answer (B) is incorrect because there is no
subject for the verb arrived. Answer (D) is the best answer because
there is a subject, student, for the verb, arrived, and there is a connector,
after, to join the two clauses.
EXERCISE 6: Each of the following sentences contains more than one
clause. Underline the subjects once and the verbs twice. Circle the connectors.
Then indicate if the sentences are correct (C) or incorrect (I).
1. After the plane circled the airport, it landed on the main runway. (C)
Analysis:
Both clauses have subject and verb.
The connector "when" is correct, too.
2. The registration process took many hours since the lines so long. (I)
Analysis:
The second clause has no verb. It should be the lines were so long.
The connector "since" is correct.
3. This type of medicine can be helpful, it can also have some bad side effects. (I)
Analysis:
Both clauses are correct but there is no connector.
4. The waves were amazingly high when the storm hit the coastal town. (C)
Analysis:
Both clauses and connector are correct.
5. We need to get a new car whether is on sale or not. (I)
Analysis:
Second clause has no subject. It should be it is on sale or not
Connector "whether" is correct
