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.现在完成时的否认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，其否认式、疑问式和简单答复形式如下：否认式疑问式I have not (havent) studied.Have I studiedYou have not (havent) studied.Have you studiedHe has not (hasnt) studied.Has he studied否认疑问式简单答复肯定/否认Have I not (H

2、avent I) studiedYes, you have. No, you havent.Have you not (Havent you) studiedYes, I have. No, I havent.Has he not (Hasnt he) studiedYes, 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。She has arriv

3、ed.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，如1993，last ter

4、m, 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. India has been an i

He has been in hospital _ October.1. since 2. for 3. for 4. since 5. since 6. for 7. for 8. since2表示短暂意义的动词如arrive, leav

6、e, 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 minutes2have (has) been和ha

7、ve (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。试比拟：Where has he been他刚刚到哪里去了？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 1976, two days ago, just now, whe

8、n 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.我经常在街上看见他。They h
