(現(xiàn)在、過去、將來)完成進行時是(現(xiàn)在、過去、將來)完成時的強調(diào)形式,將放在完成時態(tài)部分講述。
三、完成時態(tài)
完成時態(tài)通常表示已完成或從事的動作。它可分為:
1. 現(xiàn)在完成時
(1)現(xiàn)在完成時用來表示對目前狀況仍有影響的,剛剛完成的動作(常與yet,already,just連用),或者過去某一時刻發(fā)生的,持續(xù)到現(xiàn)在的情況(常與for,since連用)。例如:
1)i have just finished my homework.
2)mary has been ill for three days.
(2)常與現(xiàn)在完成時連用的時間狀語有:since, for, during, over等引導出的短語;副詞already, yet, just, ever, now, before, often, lately, recently等;狀語詞組this week (morning, month, year), so far, up to now, many times, up to the present等。例如:
1)i haven’t been there for five years.
2)so far, she hasn’t enjoyed the summer vacation.
3)there have been a lot of changes since 1978.
(3)完成時態(tài)可用在下列結(jié)構(gòu)中:
this (that, it) is (was) the first (second…) time +定語從句;this (that, it) is (was) the only (last) + n +定語從句;this (that, it) is (was) +形容詞更高級+ n +定語從句。如果主句的謂語動詞是一般現(xiàn)在時,從句的謂語動詞通常用現(xiàn)在完成時;如果主句謂語動詞是一般過去時,從句謂語動詞通常用過去完成時。例如:
(1)this is one of the rarest questions that have ever been raised at such a meeting.
(2)there was a knock at the door. it was the second time someone had interrupted me that evening.
