1、.一、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
2、I not (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, hehasnt.(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
3、。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 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:a)since和for的区别since后接时间点
4、,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 inIreland_ Monday.2. Jill has been in Ireland _ three days.3. His aunt has lived in Australia _15 days.4. Mary is inher office. She has been there _ 7 oclock.5. Ind
5、ia has been an independent country _1974.6. The bus is late. Theyve 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.1. since 2. for 3. for 4. since 5. since 6. for 7. for 8. since2)表示短暂意
6、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 2weeks.The old man has _ _ for 4 months.They have _ _ only for 5 minutes2)
7、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 toCanada.他们到过加拿大。(现在已经不在加拿大)They have gone toCanada.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
8、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: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 h
