[TOEIC Test] Part 5 : Incomplete Sentences (VERBS : TENSE)


Prefix :
The various verb tenses have four principal verb forms :
SIMPLE PRESENT | SIMPLE PAST | PAST PARTICIPLE | PRESENT PARTICIPLE
walk | walked | walked | walking
do | did | done | doing
speak | spoke | spoken | speaking
come | came | come | coming

To choose the appropriate tense, look for clues in the sentences. These clues can be adverbs (time markers), other verbs in the sentences, or the verbs themselves (which may be limited to certain tenses).

Patterns To Remember :
* Certain time markers (now, tomorrow, since, etc.) indicate the tense of a verb.
INCORRECT :
deal with his firm since 1988.
CORRECT :
have dealt with his firm since 1988.

* The verb in the main clause of a sentence determines the appropriate tense in the dependent clause.
INCORRECT :
He signed the release before he will read it.
CORRECT :
He signed the release before he read it.

* Stative verbs (seem, become, know, understand, be , etc) cannot be used in the continuous.
INCORRECT :
If I'm understanding what you mean, I have to agree.
CORRECT :
If I understand what you mean, I have to agree.

Practices :
* The survey indicated that profits are up by 20 percent the first two quarters of this year; business ?
(A) is being good
(B) were good
(C) good
(D) has been good
Ans. A > D
題目指出過去兩個月, 所以是已經發生. has been good
