现在完成时讲解及练习题及答案

1、时态讲解：现在完成时（1）构成：现在完成时由助动词have + 过去分词构成，助动词have 有人称和数的变化。第三人称单数用has，其余用have.现在完成时的否定式直接在助动词后面加上not、疑问式是把助动词提到主语之前。以study 为例，其否定式、疑问式和简单回答形式如下：否定式疑问式I have not (havent studied.Have I studied?You have not (havent studied.Have you studied?He has not (hasnt studied.Has he studied?否定疑问式简单回答（肯定/否定）Have I n

2、ot (Havent I studied?Yes, you have. No, you havent.Have you not (Havent you studied?Yes, I have. No, I havent.Has he not (Hasnt he studied?Yes, he has. No, he hasnt.（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。Im sure weve met before. 我肯定我们以前见过面。Sh

3、e 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 havent heard from her these days. 这些日子我没有收到她的信。We havent 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：1）since和for的区别since后接

4、时间点，如1993，last term, yesterday, the time I got therefor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 has been in Ireland _ three days.3. His aunt has lived in Australia _15 days.4. Mary is in her office. She has been there _ 7 o'

5、clock.5. India has been an independent country _1974.6. The bus is late. They've been waiting _ 20 minutes.7. Nobody lives in those houses. They have been empty _ many years.8. Mike has been ill _a long time. He has been in hospital _ October.2）表示短暂意义的动词如arrive, leave, borrow, buy, begin, start,

6、 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.3）have (has been 和have (has

7、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）.4）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,

8、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：She has already come. 她已经来了。I havent read it yet. 我还没读过这个。I have met him before. 我从前曾见过他。Ma Hong has always been a good student. 马红一直是个好学生。I have often seen him in the street

9、. 我经常在街上看见他。They have never been to Yanan. 他们从未去过延安。I haven't seen him lately. 我近来没看到他。regular VerbsBase FormPast FormPast Participlebearborebornbeatbeatbeatenbecomebecamebecomeblowblewblownbringbroughtbroughtbuildbuiltbuiltbuyboughtboughtcatchcaughtcaughtchoosechosechosencomecamecomedodiddonedr
