动词的时态
不同时间和方式发生的动作或状态要用谓语动词的不同形式来表示，这种表示动作或状态发生时间和方式的动词形式称作动词时态。
七种时态：
①一般现在时
②一般过去时
③现在进行时
④过去进行时
⑤一般将来时
⑥现在完成时
⑦过去完成时
过去完成时
1.过去完成时的含义:
过去完成时表示在过去某个时间或某个动作之前发生的动作，它表示动作发生的时间是“过去的过去”，它是一种相对于一般过去时的时态，没有一般过去时就没有过去完成时。
2.过去完成时的构成:
由“助动词had+动词的过去分词”构成。
否定式为“had
not+动词的过去分词”，had
not缩写为hadn’t。
3.过去完成时的用法:
(1)表示一动作或状态在过去某一时间或动作之前已经完成，即发生在“过去的过去”。这个过去的时间可以用by,
before等介词短语或者一个时间状语从句来表示。
例：我醒来时，雨已经停了。
When
I
woke
up,
it
had
stopped
raining.
(2)表示某一动作或状态在过去某时之前已经开始，一直延续到这一过去的时间。常用表延续的时间状语如by
the
end
of+过去的时间点,
by
the
time
+从句等。
例：到去年年底，她已经在这家工厂工作20年了。
By
the
end
of
last
year,
she
had
worked
in
the
factory
for
twenty
years.
4.过去完成时的判断依据:
(1)由时间状语来判定
①by+过去的时间点
例:到昨天9点钟时，她已经读完了这本书。
She
had
finished
reading
the
book
by
9
o’clock
yesterday.
②by
the
end
of+过去的时间点
例：到上个月月底，我们已经完成了所有工作。
We
had
completed
all
the
work
by
the
end
of
last
month.
(2)由“过去的过去”来判定
①含有宾语从句的复合句中句：当主句为一般过去时，且从句的动作先于主句的动作发生时，从句要用过去完成时。如在told,
said,
knew,
heard,
thought等动词后的宾语。从句中。
例：她说她以前已看过这部电影了。
She
said
that
she
had
seen
the
film
before.
②含有状语从句的复合句中，主、从句的动作发
生有先后关系，动作在前的要用过去完成时，
动作在后的要用一般过去时。
例:我到达车站时，火车已经离开了。
When
I
got
to
the
station,
the
train
had
already
left.
③表示意向的动词，如hope,
wish,
expect,
think,
intend,
mean,
suppose等，用过去
完成时表示“原本……，但未能”。
例：我们本希望你能来，但你没来。
We
had
hoped
that
you
would
come,
but
you
didn’t.
She
said
she
had
worked
in
a
foreign
company
for
five
years
before
she
became
an
English
teacher.
她说在她成为一名英语教师之前已在一家外国公司工作了5年。
注意：
过去完成时常用于宾语从句中：主句谓语为过去式（said,
asked,
told等），从句用过去完成时，此时从句中的动作发生在主句的动作之前。
1)当我到达学校的时候，我才意识到我把书包忘在家里了。
_______
I

school,
I

that
I
______
______
my
