注意理解即可

4. 过去进行时还有一个特殊的用法:表示一个动作发生时另一个动作正在进行并且还在延续.

这里第一个动作是短时间动作可以理解为刚发生的动作并且会很快结束,或者做描述后一个动作发生时间的参照时间,一般做主句.

另一个动作与主句是同时发生的但是持续时间长。一般充当宾语从句或时间状语从句

例:

Granny fell asleep when she was reading.奶奶看书的时候睡着了

It was raining when they arrive here. 他们到这的时候外面正在下雨

现在完成时

疑问句回答句式较为固定要牢记

1. 表示一个过去发生并已完成的动作对现在产生影响或结果,强调的是现在的状况(表示'已完成')。如:

He has left the city. 他已经离开了这座城市(结果:他目前不在这个城市)

2. 表示一个动作开始于过去,持续到现在,(可能会持续延续下去)的动作或状态(表示'已发生但未完成')。

He has taught in our school for 320years. 他已经在这所学校教了20年的书了.(30年前就开始教书且还会持续教下去。)

He has lived here since 2006. 他从2006年开始就住在这里了

注意 瞬间动词通常是不能用现在完成时表持续性的,但其否定结构则可以。如:

She hasn't seen you for ages. 她已经很久没见你了。

His father hasn't touched beer for a whole week. 他爸爸已经一周没喝酒了。

3. 表示过去到现在为止反复发生的动作或多次出现的状态,常与表示频度的副词always, often, every day等连用。如:

I have often heard that he is the cleverest person in that company. 我经常听到说他是公司最聪明的那个。

4. 在时间和条件状语从句中,现在完成时表示将来某时完成的动作。如:

I'll go to your home when I have finished my homework. 我写完作业就会回家。

If it has stopped snowing in the morning, we'll go the park. 如果早上雪停了,我们将去公园。

5. 与现在完成时连用的常见词语

6. 现在完成时与一般过去时的区别

(1)强调内容不同,两者所表示的动作都发生在过去,但现在完成时强调对现在的影响或结果;一般过去时只表示过去的事实,于现在没有任何关系。

如:

I have closed the door. 我已经关上门了。(现在门是关着的)

I closed the door just now. 我刚才关上门了。(仅仅表示刚才'关门'这个动作)

(2) 现在完成时常与模糊的时间状语连用(如for, since, so far, ever, never, just, yet, till/until, up to now, always等),或者干脆没有时间状语;

而一般过去时常与具体的时间状语连用(如yesterday, last night, …ago, in 1980, in February等)。

They built three schools last year. 他们去年建了三所学校。

They have built three schools so far. 到目前为止,他们已经建了三所学校。

(3) 现在完成时表示持续时一般使用延续性动词(如live, teach, work, know等);

而一般过去时常使用瞬间动词(如begin, buy, die, marry等)。如:

He has lived in Hangzhou since last spring. 去年春天,他一直住在杭州。

My grandfather bought the car five years ago. 五年前,我爷爷买了这辆车。

例. 易错点辨析

(1) 考生容易把一些瞬间动词用现在完成时表达,这是错误的。如:

(×) He has died for two years. 他死了两年了。

(√) He has been dead for two years. 他死了两年了。

(√) He died two years ago. 两年前,他死了。

(×) The film has begun for 10 minutes.

(√) The film has been on for 10 minutes. 电影开演十分钟了

(√) The film began 10 minutes ago.十分钟前,电影开始了。

(×) She has married for three years.

(√) She has been married for three years. 她结婚有三年了。

(√) She married Mike three years ago. 三年前,她和迈克结婚了。

(2) 考生不懂如何区分have been to和have gone to,尽管两者均可后接地点,但have been to表示去过某地(现在已经回来了),have gone to表示到某地去了(现在还没回来)。如:

She has been to Paris (three times). 她已经去过巴黎(三次)了。

She has gone to Paris. 她去巴黎了。(还没回来)
