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. Kate's never seen Chinese films，____ ? A. hasn't she B. has she C. isn't 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Kate's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常用在否定句、疑问句中，故填hasn't, 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; finish B. Are; finishing C. Did; finish D. Have; finished 2. -______ you ______anywhere before? -Yes, but I can't 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 letter from him since he left.
A. didn't receive B. haven't got C. didn't have D. haven't 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. 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。
