题目内容
9.-Look!Someone _______ the classroom.-Well,it wasn't me.I didn't do it.( )
| A. | is cleaning | B. | was cleaning | C. | has cleaned | D. | will clean |
分析 --看,有人已经把教室打扫干净了
--呃,不是我做的.我没有打扫.
解答 答案:C.
根据it wasn't me.I didn't do it,可以判断打扫教室这个动作发生在过去,对现在造成了影响,教室已经打扫了,所以这里用现在完成时,结构为:have/has+动词过去分词.主语是someone,是个不定代词,作主语谓语动词用单数,故选C.
点评 本题考查了现在完成时的用法.解答时注意结构为:have/has+动词过去分词.
