Some sentence in English have just one subject and verb, and it is very important for you to find the subject and verb in these sentences. In some sentences it is easy to find the subject and verb. However, certain structures, such as objects of preposition, appositives, and participles, can cause confusion in the locating the subject and verb because each of these structures can look like a subject or verb. An object of the prepositions or an appositives can be mistaken for a subject, while a participle can be mistaken for a verb.
Therefore, you should be able to do the following in sentences with one subject and verb: (1)
be sure the sentence with one subject and a verb, (2) be careful of objects of prepositions and appositive when you are looking for the subject, and (3) be careful of objects present participles and past participles when you are looking for the 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 structure questions on the TOEFL tes 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 the verb.
Example 1:
____________ 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 contains the singular subject
traffic that agrees with the singular verb
was. Answer (A),
yesterday, and answer (B),
in the morning, are not subject, it is not correct because
cars is plural and it does not agree with the singular verb
was.
Example 2:
In this example you should notice immediately that the sentences has a subject
engineers and that there is no verb. Because answer (B),
are needed, is a verb, it is the best answer, Answer (A), (C), and (D) are not verbs, so they are not correct.
Example 3:
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 from of the verb
be is needed to make the sentence complete. Answer (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 because of
going. Answer (D) is the best answer;
will be together with
going is a complete verb.
So, the key words of this TOEFL structure trick is "A sentence must have at least one
subject and one
verb.
