四种完成时态
▲
完成时态的构成
句型
时态
现在完成
过去完成
将来完成
过去将来完成
主系表
have (has) been
had been
will have been
would have been
主谓宾
have (has) done
had done
will have done
would have done
▲
现在完成时态的基本用法
1.
表示一个
过去发生的动作
对
现在产生的结果和影响
。
应该明确现在完成时态属于现在时态的范畴。它所强调的不是过去发生的动
作，而是对现在产生的结 果和影响。否则用一般过去时态就够了。请看下面的对话。
●
A
－
We
will send
some one to America.
我们要派一个人去美国。
B
－
I
have been
there.
我去过美国。
= I
was
there and I
know
the country very well.
Would
you send me there?
我去过那儿，很了解那个国家。能派我去吗？
C
－
I
have not been
there.
我还没去过那儿呢。
= I
didn’t go
to America. It
is
my turn.
我没去过。这次该我了。
上面对话的前提是大家都抢着去美国。
所以
B
用现在完成时态是想说明自己有
经验，派他去好。而
C
用现在 完成时态是说自己没去过，轮也该轮到他了。两句都
是强调对现在产生的影响
。
Did you have lunch?
Have
you
had
lunch?
Did you study English?
Have
you
studied
English?
Laochang died?
Laochang
has died?
Who was herer?
Who
has been
here?
Have
you
done
your homework
2.
表示过去发生的动作一直持续到现在
。
通常用于持续性较强的动词，
例如：
live, study, wait for, be
等等，
并且常常与
since,
for
连用，
since
给出的是过去的一个时间点，如
since
1958,
而
for
往往给出的是一
个时间段，如
for three years
。
●
He
has studied
English
for
eight years.
●
Since
1980, they
have known
each other.
注：
完成时态表示延续的用法不可跟非延续动词连用，如：
die,
go
, leave,
receive
等。请看下面例句：
╳
His father
has died
for
three years.
●
His father
has been
dead for three years.
第一 句是错的。“死”这个动作不可能延续。但一种状态却可以延续。第二句
用主系表句型是对的。
▲
过去完成时态，将来完成时态和过去将来完成时态
学习完成时态应注意，所有完成时态在“态”的概念上是一样的，现在完成时
态、过 去完成时态、将来完成时态、过去将来完成时态所不同的只是时间上的概念。
所以我们只要掌握现在完成 时态，然后在时间上向过去推便是过去完成时态，向将
来推便是将来完成时态。
3
完成时态在主从句中的用法
完成时态除上面讲到的两种基本用法之外，< br>在主从句中通常可以用来表示主句
与从句动作发生的先后次序
。
●
Do
you
know
he
has finished
his homework?
现在完成时态“
has finished
”
表示发生在一般现在时态“
know
”之前。
●
I
heard
he
had bought
a new car.
过去完成时态“
had bought
”表示发生在过去时态“
heard
”之前。
现在完成时态“
have had supper
”强调吃过饭 之后，即强调从句动作发生在主
句之前。从上面几个例句可以看出，在主从句中现在完成时态往往表示发 生在另一
个现在时态的动作之前，而过去完成时态则表示发生在另一个过去时态的动作之前。
请 注意下面的例句：
以上简单地介绍了在主从句中完成时态的用法。
