Structure and Written Expression

SKILL 1: BE SURE THE SENTENCE HAS A SUBJECT AND A VERB
You know that a sentence in English should have a subject and a verb. The most common types of problems that you will encounter in the Structure section of the TOEFL test have to do with subjects and verbs: perhaps the sentence is missing either the subject or the verb or both, or perhaps the sentence has an extra subject or verb.

Example I
____ was backed up for miles on the freeway.
(A) Yesterday
(B) In the morning
(C) Traffic
(D) Cars
In this example you should notice immediately that there is a verb (was), but there is no subject. Answer (C) is the best answer because it is a singular subject that agrees with the singular verb was. Answer (A), yesterday, and answer (B), in the morning, are not subjects, so they are not correct. Although answer (D), cars, could be a subject, it is not correct because cars is plural and it does not agree with the singular verb was.

Example II
Engineers____ for work on the new space program.
(A) necessary
(B) are needed
(C) hopefully
(D) next month
In this example you should notice immediately that the sentence has a subject (engineers), and that there is no verb. Because answer (B), are needed, is a verb, it is the best answer. Answers (A), (C), and (D) are not verbs, so they are not correct.

Example III
The boy _____ going to the movies with a friend.
(A) he is
(B) he always was
(C) is relaxing
(D) will be
This sentence has a subject (boy) and has part of a verb (going); to be correct, some form of the verb be is needed to make the sentence complete. Answers (A) and (B) are incorrect because the sentence already has a subject (boy) and does not need the extra subject he. Answer (C) is incorrect because relaxing is an extra verb part that is unnecessary be-cause of going. Answer (D) is the best answer; will be together with going is a complete verb.
The following chart oudines what you should remember about subjects and verbs:
