现在完成时练习题及答案

For personal use only in study and research; not for

commercial use

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

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

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：
