过去完成时
1.
过去完成时的概念:
过去完成时表示一个动作或状态在过去某一
时间或某个动作之前已完成或结束,也可能
是早已完成或结束,即“过去的过去”。
2.
过去完成时的构成:
助动词
had
+
动词的过去分词
3.
过去完成时的标志及一般用法:
(1)用于表示过去某一时刻前已经发生的动作或
存在的状态,常与by,
before,
after,
until,
when等引导的过去时间状语连用。
例如:我的手表修了以后,走得很准。
My
watch
went
well
after
I’d
had
it
repaired.
(2)过去完成时用于宾语从句中,表示从句的动作
或状态发生在主句的谓语动词的动作之前。
例如:他说他去过北京两次。
He
said
he
had
been
to
Beijing
twice.
(3)有时句子中没有明显的时间状语,动作发生
时间的先后需从上下文中去判断。
例如:他刚收到一个漂亮的礼物很高兴。
He
was
very
happy.
He
had
just
got
a
beautiful
gift.
4.
过去完成时的持续用法
表示过去某一时间之前发生的动作或存在的状态
一直持续到过去某一时间,并有可能继续下去。
常与由for或since引导的表示一段时间的短语或
从句连用。
例如:你来之前我等了3个小时。
I
had
waited
for
3
hours
before
you
came
here.
5.
一般过去时与过去完成时的区别
过去完成时在时间上强调过去的过去,而一般过去时只强调过去某一特定的时间。
当两个或两个以上动作先后发生,并用and或but连接时,只需用一般过去时。
例如:他们把椅子移到餐桌附近,坐下来开始吃
晚餐。
They
moved
the
chairs
near
the
table,
sat
down
and
began
to
have
supper.
到昨天早上九点,我们已经完成了工作。
By
nine
o’clock
yesterday
morning,
we
had
finished
our
work.
6.
现在完成时与过去完成时的区别
现在完成时表示过去发生的动作持续到现在,或对现在产生某种影响;
过去完成时表示较早的过去发生的动作持续到过去的某一时刻,或对过去某一时刻产生某种影响。
