现在完成时练习题及答案(精华版)
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、 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。I’m sure we’ve met before. 我肯定我们以前见过面。 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 haven’t heard from her these days. 这些日子我没有收到她的信。 We haven’t 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后接时间点，如1993，last term, yesterday, the time I got there for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'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, 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) 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, 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 haven’t 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。

His uncle has already posted the photos to him. (改为否定句) His uncle ______ posted the photos to him ______. 析：already常用在肯定句中，yet常用在否定句、疑问句中，故填hasn't, yet。 3. -Ann has gone to Shanghai. -So ______her parents.

A. went to B. gone to C. been in D. been to 析：据句中的have，排除A，B项意为"去某地了"，C项意为"一直呆在某地"，D项意为"去过某地"，符合题意，故选D。 2. My parents ______ Shangdong for ten years. A. have been in B. have been to C. have gone to D. have been 析：本题句中有"for+段时间"结构，据此可排除C，B项意为"去过某地"，不合题意，D项缺介词，故选A。 四、现在完成时与其他时态的联系和区别。如： 1. Sun's aunt has gone there for ten years.(改成正确的句子) 析：非延续性动词与"段时间"连用时，除了把非延续性动词改成延续性动词外，还可把动词改为一般过去时或借助句型"It's +段时间+since+从句"进行句子转换。故答案为：Sun's aunt has been there for ten years. /Sun's aunt went there ten years ago. /It's ten years since Sun's aunt went there. 2. Susan has been in this city for more than ten years.(改为同义句) ________more than ten years ____Susan ______to this city. 析：据上题分析，且since引导的从句要用一般过去时，故填It is, since, came。 3. I won't go to the concert because I ____my ticket. A. lost B. don't lose C. have lost D. is coming 析：因我丢了票的动作发生在过去，而且对现在造成了我不能参加音乐会的结果，符合现在完成时所表示的含意，故选C。 一、单项选择 1、Both his parents look sad.
