You know that 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 are related to subjects and verbs; perhaps the sentence is missing either the subject, or the verb, or both; perhaps the sentence has an extra subject or verb.
Example I
_____was ringing continuously for hours.
(A) Loudly
(B) In the morning
(C) The phone
(D) The bells
Analysis :
in this example, you should notice immediately that there is a verb, was ringing, but there is no subject. Answer (C) is the best answer because it is a singular subject that agrees with the singular verb was ringing. Answer (A), loudly, and answer (B), in thw morning, are not subjects, so they are not correct. altough answer (D), bells, could be a subject, it is not correct because bells is plural and it does not agree with the singular verb was ringing.

Skill 2 : Objects of Preposition
An object of a preposition is a noun or a pronoun that comes after a preposition such as in, at, of to, by, behind, and on to form a prepositional phrase.
The trip (to the island) (on Saturday) will last (for three hours)
This sentence contains three objects of prepositions. Island is the object of the preposition to; Saturday is the object of the preposition on; hours is the object of the preposition for.
An object of a preposition can cause confusion in the Structure section of the TOEFL test because it can be mistaken for the subject of a sentence.
Example
To Mike ____ was a big surprise.
(A) really
(B) the party
(C) funny
(D) when
In this example, you should look first for the subject and the verb. You should notice the verb was and should also notice that there is no subject. Do not think that Mike is the subject; Mike is the object of the preposition to, and one noun cannot be both a subject and an object at the same time. Because a subject is needed in this sentence, answer (B), the party, 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.
Now, Let's do and analyze the exercise below:

Skill 3 : Present Participles
Present participles can-cause confusion in the Structure section of the TOEFL test because a present participle can be either an adjective or a part of the verb. A present participle is the - ing form of the verb. It is part of the verb when it is preceded by some form of the verb be.
The train is arriving at the station now. (Arriving is VERB)
In this sentence, arriving is part of the verb because it is accompanied by is.
A present participle is an adjective when it is not accompanied by some form of the verb be.
The train arriving at the station now is an hour late. (Arriving is ADJECTIVE)
In this sentence, arriving is an adjective and not part of the verb because it is not accompanied by some form of be. The verb in this sentence is is.
The following example shows how a present participle can be confused with the verb in the Structure section of the TOEFL test.
Example
The film ____ appearing at the local theater is my favorite.
(A) now
(B) is
(C) it
(D) was
In this example, if you look at only the first words of the sentence, it appears that film is the subject and appearing is part of the verb. If you think that appearing is part of the verb, you might choose answer (B), is, or answer (D), was, to complete the verb. However, these two answers are incorrect because appearing is not part of the verb. You should recognize that appearing is a participial adjective rather than a verb because there is another verb in the sentence, is. In this sentence, there is a complete subject, film, and a complete verb, is, so this sentence does not need another subject or verb. The best answer to this question is answer (A).
The film ____ appearing at the local theater is my favorite.
(A) now
(B) is
(C) it
(D) was
In this example, if you look at only the first words of the sentence, it appears that film is the subject and appearing is part of the verb. If you think that appearing is part of the verb, you might choose answer (B), is, or answer (D), was, to complete the verb. However, these two answers are incorrect because appearing is not part of the verb. You should recognize that appearing is a participial adjective rather than a verb because there is another verb in the sentence, is. In this sentence, there is a complete subject, film, and a complete verb, is, so this sentence does not need another subject or verb. The best answer to this question is answer (A).
EXERCISE 3
Each of the following sentences contains one or more present participles. Underline the subjects once and the verbs twice. Circle the present participles, and label them as adjectives or verbs. Then indicate if the sentences are correct (C) or incorrect ( I ).
1. The crying baby needs to be picked up. (C)
ADJ.
2. The clothes are lying the floor should go into the washing machine. ( I )
VERB

8. The letters needing immediate answers are on the desk. (C)
9. The boring class just ending a few minutes ago. ( I )
10. The fast-moving clouds are bringing freezing rain to the area. (C)
Skill 4 : Past Participles
Past participles can cause confusion in the Structure section of the TOEFL test because a past participle can be either an adjective or a part of the verb. The past participle is the form of the verb that appears with have or be. It often ends in -ed, but there are also many irregular past participles in English.
The mailman has left a letter in the mailbox. (Left is VERB)
The classes were taught by Professor Smith. (Taught is VERB)
In the first sentence, the past participle left is part of the verb
because it is accompanied by has. In the second sentence, the past
participle taught is part of the verb because it is accompanied by were.
A past participle is an adjective when it is not accompanied by some form of be or have.
The letter left in the mailbox was for me. (Left is ADJECTIVE)
The classes taught by Professor Smith were very interesting. (Taught is ADJECTIVE)
In the first sentence, left is an adjective rather than a verb because
it is not accompanied by a form of be or have (and there is a verb, was,
later in the sentence). In the second sentence, taught is an adjective
rather than a verb because it is not accompanied by a form of be or have
(and there is a verb, were, later in the sentence).
The following example shows how a past participle can be confused with the verb in the Structure section of the TOEFL test.
Example
The bread _____ baked this morning smelled delicious.
(A) has
(B) was
(C) it
(D) just
The following example shows how a past participle can be confused with the verb in the Structure section of the TOEFL test.
Example
The bread _____ baked this morning smelled delicious.
(A) has
(B) was
(C) it
(D) just
In this example, if you look only at the first few words of the sentence, it appears that bread is the subject
and baked is either a complete verb or a past participle that needs a
helping verb. But if you look further in the sentence, you will see the
verb smelled. You will then recognize that baked is a participial
adjective and is therefore not part of the verb. Answers
(A) and (B) are incorrect because baked is an adjective and does not
need a helping verb such as has or was. Answer (C) is incorrect because
there is no need for the subject it. Answer (D) is the best answer to this question.
EXERCISE 4: Each of the following sentences contains one
or more past participles. Underline the subjects once and the verbs
twice. Circle the past participles, and label them as adjectives or
verbs. Then indicate if the sentences are correct (C) or incorrect (I).

Skill 5 : Coordinate Connector
Many sentences in English have more than one clause. (A clause is a group of words containing a subject and a verb.) When you have two clauses in an English sentence, you must connect the two clauses correctly. One way to connect two clauses is to use and, but, or, or so between the clauses.
The sun was shining and the sky was blue.
The sky was blue, but it was very cold.
It may rain tonight, or it may be clear.
It was raining outside, so I took my umbrella.
In each of these examples, there are two clauses that are correctly joined with a coordinate connector—and, but, or, or so—and a comma (,).
The following example shows how this sentence pattern could be tested in the Structure section of the TOEFL test.
Example
I forgot my coat, ____ I got very cold.
(A) then
(B) so
(C) later
(D) as a result
In this example, you should notice quickly that there are two clauses, I
forgot my coat and I got very cold. This sentence needs a connector to
join the two clauses. Then, later, and as a result are not connectors,
so answers (A), (C), and (D) are not correct. The best answer is answer (B) because so can connect two clauses in this manner.
The following chart lists the coordinate connectors and the sentence pattern used with them.
EXERCISE 5
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
