1.4 TENSES [ PAST / PRESENT / FUTURE PERFECT TENSE]
Perfect verb tense is used to show an action that is completed and finished, or perfected. This tense is expressed by adding one of the auxiliary verbs — have, has, or had — to the past participle form of the main verb.
PRESENT PERFECT [SUB + HAVE / HAS + M.V (past participle form)]
Eg. I have eaten already.
she just has written a letter to her brother.
The present perfect is used to indicate a link between the present and the past. the time of the action is before now but not specified, and we are often more interested in the result that in the action itself.
PAST PERFECT [SUB + HAD + M.V (past participle form)]
The past perfect refers to a time earlier than before now. it is used to make it clear that one event happened before another in the past. it does not matter which event is mentioned first - the tense makes it clear which one happened first.
Eg. I had eaten when I arrived his home.
she had written a letter to her brother before she went out.
FUTURE PERFECT [SUB + SHALL/WILL + HAVE + M.V (past participle form)]
The future perfect tense refers to a completed action in the future. When we use this tense we are projecting ourselves forward into the future and looking back at an action that will be completed some time later than now. it is most often used with a time expression.
Eg. I will have eaten by this time next week.
she will have written a letter to her brother before she goes out.
