例:肯定句I have worked. He has worked.

否定句I have not (haven't ) worked. He has not (hasn't )worked .

疑问句Have you worked ? Has he worked ?

回答Y es,I have. / No , I haven't . Y es, he has./ No, he hasn't.

二.功能及意义

1.表示一个动作发生在过去,对现在仍有影响,但没有具体的过去时间修饰。常由下列副词修饰:ever曾经,never从不,already已经,yet还(未),(yet 只用在否定句和疑问句中),just刚刚,recently,lately近来,so far 迄今为止= until now, up to now,before 以前

例:Have you ever been to the Great Wall? 你曾经去过长城吗?

I have already returned your money.我已经把钱还给你了。

2 表示一个动作发生在过去,一直持续到现在刚刚结束或者仍在继续。常常与下列时间状语连用:

→for + 一段时间

I have learned English for 8 years

→since + 过去的一个时间点

I have learned English since 2001

→since + 一段时间+ ago

I have learned English since 8 years ago

→since + 时态为一般过去时的时间状语从句

I have learned English since I was 5 years old

→ in the past/last +时间段

We have had two English exams in the past two months近两个月来我们进行了2次英语考试

Great changes have taken place in my hometown in the past ten years 近十年来我的家乡发生了巨大的变化。

三延续性动词与短暂性动词的用法

①现在完成时中,与一段时间连用时应注意句中的谓语动词须是延续性动词,非延续性动词不可和一段时间连用。

我离开这所学校已经八年了。

误:I have left this school for eight years(×)

他借用我的词典已经两天了

误:He has borrowed my dictionary for two days(×)

②非延续动词与一段时间连用时,可做相应转化

因此①中例句正确形式分别为

我离开这所学校已经八年了。

正:I have been away from this school for eight years(√)

他借用我的词典已经两天了

正:He has kept my dictionary for two days(√)

其它非延续性动词与时间段连用时的变形

buy→have borrow→ keep,

fall asleep →be asleep leave →be away

begin →be on die →be dead,

join→ be in或be a member of return→ be back

come/arrive→ be in get up →be up,

marry →be married catch a cold→ have a cold

③在否定句中短暂性动词可与段时间连用

I haven't gone to see him for several months(我已经好几个月没有去看他了)

I haven't bought anything for two months

四区分

① have been to +地点; 表示去过某个地方(已经回来),常与ever, never ,几次,等连用

②have gone to +地点: 表示到地方去了(还没回来)

③have been in+地点:表示到了某个地方(多久了),常与for + 段时间连用

比较:He has been to China twice(曾经去过,现在不在中国)

He has gone to China 他到中国去了.(他可能已在去中国的路上,或已到中国,总之,现在不在这里)

He has been in China for two years(他到中国已经两年了)

五对完成时的提问用how long.....? 不能用when... ?

六现在完成时常用句型

1 It is the first/second time....that....结构中的从句部分,用现在完成时

It is the first time that I have visited the city

这是我第一次参观这座城市

It is the third time that the boy has been late

2 This is the... that.. 结构,that 从句要用现在完成时

自从上一次我们相遇到现在已经是五年了

It's / It has been 3 months since the man died 那人死去3个月了

4 一段时间+ 完成时结构+ since 引导的时间状语从句

Two years has passed since I came here.

七现在完成时和一般过去时的区别

现在完成时表示过去发生的某一动作对现在造成的影响或结果,强调的是现在的情况,所以它不能和表示过去的时间状语连用,如yesterday, last night, three weeks ago, in 1998 等。而一般过去时只表示过去的动作或状态,和现在不发生联系,它可以和表示过去的时间状语连用

I have seen the film 我看过这部电影(我了解这部电影的内容)

I saw the film last week 我上周看了这部电影(只说明shangxingqi
