32e Use verb tenses appropriately.

Verb tenses show when the action takes place. The three simple tenses are the present tense, the past tense, and the future tense.

PRESENT TENSE I ask, write
PAST TENSE I asked, wrote
FUTURE TENSE I will ask, will write

More complex aspects of time are expressed through progressive, perfect, and perfect progressive forms of the simple tenses.

PRESENT PROGRESSIVE she is asking, is writing
PAST PROGRESSIVE she was asking, was writing
FUTURE PROGRESSIVE she will be asking, will be writing
PRESENT PERFECT she has asked, has written
PAST PERFECT she had asked, had written
FUTURE PERFECT she will have asked, will have written
PRESENT PERFECT PROGRESSIVE she has been asking, has been writing
PAST PERFECT PROGRESSIVE she had been asking, had been writing
FUTURE PERFECT PROGRESSIVE she will have been asking, will have been writing

The simple tenses locate an action only within the three basic time frames of present, past, and future. Progressive forms express continuing actions; perfect forms express actions completed before another action or time in the present, past, or future; perfect progressive forms express actions that continue up to some point in the present, past, or future.

Editing Verb Tenses

AT A GLANCE

If you have trouble with verb tense in standard English, make a point of checking for these common trouble spots as you proofread.

  • Problems with verb form: writing seen for saw, for example, which confuses the past-participle and past-tense forms. (32c)
  • Problems with tense: using the simple past (Uncle Charlie arrived) when meaning requires the present perfect (Uncle Charlie has arrived). (32e)
  • Think carefully before using a regional or ethnic variety of English (she nervous) in situations calling for standard academic English (she is nervous). (See Chapter 22.)
