文档简介
1、现在完成时一、其构成助动词have (has) +动词过去分词构成现在完成时。如:1. Kates never seen Chinese films,_ ? A. hasnt she B. has she C. isnt she D. is she析:陈述句部分含否定词never,简略问句部分要用肯定式,又因Kates是Kate has的缩写,故选B。2. 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
2、句、疑问句中,故填hasnt, yet。3. -Ann has gone to Shanghai. -So _her parents. A. has B. had C. did D. have析:so+助/系/情态动词+主语结构中的动词形式应与前句结构中动词形式保持一致,又后句的主语为her parents是复数,故选D。二、其用法与标志词(一)当句中有never, ever, just, already, yet, before等时,常用现在完成时。如:1. -Mum, may I go out and play basketball? -_ your homework yet? A. Do
3、; finish B. Are; finishing C. Did; finish D. Have; finished2. -_ you _anywhere before? -Yes, but I cant remember where I_A. Did; surf; surfed B. Have; surfed; surfed C. Did; surf; have surfed D. Have; surfed; have surfed析:据yet和before可知,应用现在完成时,故1题选D,2题选D。(二)当句中有for +段时间或since +点时间等时,主句常用现在完成时,谓语动词必须
4、是延续性动词,若是非延续性动词,要改为延续性动词或表状态的词(短语)。如:1. His brother has been to Stone Forest twice_he came to Yunnan. A. after B. before C. since D. for析:主句用的是现在完成时,而从句用的是一般过去时,故选C。2. Tom_the CD player for two weeks.A. has lent B. has borrowed C. has bought D. has had析:A、B、C均为非延续性动词,在肯定句中不与表段时间的短语连用,故选D。3. I_a lett
5、er from him since he left. A. didnt receive B. havent got C. didnt have D. havent heard析:据since可知,应排除A、C,hear from sb.=receive/get/have a letter from sb.意为收到某人的来信,故选B。三、have/has been (to, in)/have/has gone (to)的区别。如:1. -Have you ever_Lintong to see the Terra Cotta Warriors?-Yes, I have. A. went to B
6、. 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. Suns aunt has gone there for ten years.(改成正
7、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Its +段时间+since+从句进行句子转换。故答案为:Suns aunt has been there for ten years. /Suns aunt went there ten years ago. /Its ten years since Suns 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 t
8、his 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 wont go to the concert because I _my ticket. A. lost B. dont 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. Maybe they _whats happened to him . knew . have known .
