(
2
)用法:
1
)现在完成时通常表示在
说话之前已
经完成的动作
或存在的状态。说话人强调的是该
动作或状态对现
在的
结果或影响
。
My daughter has just gone out.
我女儿刚出去。
I’m
sure we’ve met before.
我肯定我们以前见过面。
She
has arrived.
她到了。
2
)表示持续到现在的动作或状态,往往和包括现在在内的表示一段时间的状语连用,
如
recently, already, just,
lately, for…,
since…,
yet
等。如:
I haven’t heard from her these days.
这些日子我没有收到她的信。
We haven’t seen you recently.
最近我们没有见到你。
They have been away for two years.
他们离开已经两年了。
She has been with us since Monday.
★注意:
a)
since
和
for
的区别
since
后接时间点,如
1993
< br>,
last term, yesterday, the time I
got there
for
后接一段时间,表示
“
长达多久
”
,如
ten years, a while, two
days
等。
Exercise:
用
since
和
for
填空
1. Jim has
been in Ireland ______ Monday.
2. Jill

3. His aunt has lived in Australia
______15 days.

7. Nobody lives in those houses. They

8.

in hospital ______ October.
2
)表示短暂意义的动词如
arrive, leave, borrow, buy,
begin, start, die
等,在完成时当中不能和
表示一段时间的状语连用,因为它们表示的动作不可能持续。因此,不能说:
He has come here for 2 weeks.
×
The
old man has died for 4 months.
×
They have left
only for 5 minutes.
×
以上三句话可以改为:
He has
been here for 2 weeks.
The old man has
______ _______ for 4 months.
They have
_____ _____ only for 5 minutes
2
)
have (has) been
和
have (has) gone
的
区别:
表示
“
曾到过某地
”
要用
“have
(has) been”;
表示
“
已
经去某地
”
要用
“have (has)
gone”
。试比较:
Where
has he been?
他刚才到哪里去了?(已经回来了)
Where has he gone?
他上哪儿去了?(人不在)
They
have been to Canada.
他们到过加拿大。
(现在已经不在加拿大)
They have gone
to Canada.
他们到加拿大去了。
(可能在路上和已
经到加拿大)
.
3
)现在完成时不能
和表示过去的时间状语连用,如
yesterday, last year, in
1976, two days ago,
just now, when I
came in
,但可以和
already, yet,
sometimes, always, often, before, lately,
recently,
once, twice, ever,
never
等连用。例如:
