'Structure and Written Expression

SKILL 2: BE CAREFUL OF OBJECTS OF PREPOSITIONS
An object of a preposition is a noun or a pronoun that comes after a preposition, such as in, at, of, to, by, behind, on, and so on, to form a prepositional phrase.

(After his exams) Tom will take a trip (by boat).
This sentence contains two objects of prepositions. Exams is the object of the preposition after and boat is the object of the preposition by.

An object of a preposition can cause confusion in the Structure section of the TOEFL testbecause it can be mistaken for the subject of a sentence.

Example
With his friend _____ found the movie theater.
(A) has
(B) he
(C) later
(D) when
In this example you should look first for the subject and the verb. You should notice the verb found and should also notice that there is no subject. Do not think that friend is the subject; friend is the object of the preposition with, and one noun cannot be both a subjectand an object at the same time. Because a subject is needed in this sentence, answer (B), he, is the best answer. Answers (A), (C), and (D) are not correct because they cannot be subjects.

The following chart outlines the key information that you should remember about
objects of prepositions:
