Structure TOEFL skill-10

10. Adjective Clause
In Skill 9 we saw that adjective clause connectors can be used to introduce clauses that describe nouns. In Skill 10 we will see that in some cases an adjective clause connector is not just a connector; an adjective clause connector can also be the subject of the clause at the same time.

we are looking at a house that is quite expensive

In the first example, there are two clauses: we is the subject of the verb are looking, and that is the subject of the verb is. These two clauses are joined with the connector that. Notice that in this example the word that serves two functions at the same time: it is the subject of the verb is, and it is the connector that joins the two clauses. The adjective clause that is quite expensive describes the noun house.

In the second example, there are also two clauses: house is the subject of the verb seems, and that is the subject of the verb is. In this example, that also serves two functions: it is the subject of the verb is, and it is the connector that joins the two clauses. Because that is quite expensive is an adjective clause describing the noun house, it directly follows house.

The following example shows how these sentence patterns could be tested in the Structure section of the TOEFL test.

Example

______ just dropped off a package for you is my sister.

(A) The woman
(B) The woman who
(C) Because the woman
(D) With the woman

In this example, you should notice immediately that the sentence has two verbs, dropped and is, and each of them needs a subject. The only answer that has two subjects is answer (B), so answer (B) is the correct answer. The correct sentence should say: The woman who just dropped off a package for you is my sister. In this sentence woman is the subject of the verb is, and who is the subject of the verb dropped.

9. Adjective Clause Connector
An adjective clause describes a noun. Because the clause is an adjective, it is positioned directly after the noun that it describes.

In the first example, there are two clauses: this is the subject of the verb is, and I is the subject of the verb want. That is the adjective clause connector that joins these two clauses, and the adjective clause that I want to buy describes the noun house.

In the second example, there are also two clauses: house is the subject of the verb is, and I is the subject of the verb want. In this sentence also, that is the adjective clause connector that joins these two clauses, and the adjective clause that I want to buy describes the noun house.

The following example shows how these sentence patterns could be tested in the Structure section of the TOEFL test.

Example

The job _____ started yesterday was rather difficult.
(A) when
(B) was
(C) after
(D) that he

In this example, you should notice quickly that there are two clauses: job is the subject of the verb was, and the verb started needs a subject. Because there are two clauses, a connector is also needed. Answers (A) and (C) have connectors, but there are no subjects, so these answers are not correct. Answer (B) changes started into a passive verb; in this case the sentence would have one subject and two verbs, so answer (B) is not correct. The best answer to this question is answer (D). The correct sentence should say: The job that he started yesterday was rather difficult. In this sentence job is the subject of the verb was, he is the subject of the verb started, and the connector that joins these two clauses.

8. Noun Clause Connector/Subject
In Skill 7 we saw that noun clause connectors can be used to introduce noun clauses. In Skill 8 we will see that in some cases a noun clause connector is not just a connector; a noun clause connector can also be the subject of the clause at the same time. Study the clauses and connectors in the following sentences.

I know what happened yesterday
NOUN CLAUSE AS OBJECT OF VERB


We are thinking about what happened yesterday.
NOUN CLAUSE AS OBJECT OF PREPOSITION

In the first example, there are two clauses: I know and what happened yesterday. These two clauses are joined by the connector what. It is important to understand that in this sentence the word what serves two functions. It is both the subject of the verb happened and the connector that joins the two clauses.

In the second example, there are two clauses. In the first clause we is the subject of are thinking. In the second clause what is the subject of happened. What also serves as the connector that joins the two clauses. The noun clause what happened yesterday functions as the object of the preposition about.

The following example shows how this sentence pattern could be tested in the Structure section of the TOEFL test.

Example

The company was prepared for ________ happened with the economy.

(A) it
(B) the problem
(C) what
(D) when

7. Noun Clause Connector
A noun clause is a clause that functions as a noun; because the noun clause functions as a noun, it can be used in a sentence as an object of a verb (if it follows a verb) or an object of a preposition (if it follows a preposition). Study the clauses and connectors in the following sentences.

In the first example, there are two clauses, I don’t know and he said such things. These two clauses are joined with the connector why. Why changes the clause he said such things into a noun clause which functions as the object of the verb don’t know.

In the second example, the two clauses I am thinking and he said such things are also joined by the connector why. Why changes the clause he said such things into a noun clause which functions as the object of the preposition about.

The following example shows how these sentence patterns could be tested in the Structure section of the TOEFL test

Example

The citizens worry about ____ is doing.

(A) what the government
(B) the government
(C) what
(D) what the government it

In this example, the sentence contains the main subject and verb, the citizens worry, and it also contains an additional verb, is doing. The sentence needs a subject for the verb is doing and a connector to join the two clauses. The best answer is answer (A) because it has the connector what and the subject government. Answer (B) is incorrect because it does not have a connector. Answer (C) is incorrect because it does not have a subject for is doing. Answer (D) is incorrect because it has two subjects for is doing.

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.
