题目内容
9.I Mr.Smith since he moved to Shanghai.( )| A. | didn't hear from | B. | don't hear from | ||
| C. | won't hear from | D. | haven't heard from |
分析 自从他搬到上海,我没有收到史密斯先生的来信.
解答 答案:D.根据关键词since he moved to Shanghai.可知,本句是现在完成时态,since是现在完成时态的标志词,其构成为:have/has+过去分词,其否定形式在助动词后面加not,缩写为haven‘t或hasn't;主语是I是第一人称,所以助动词用have,hear的过去分词为heard.故选D.
点评 本题考查时态的辨析,要根据关键词和时间状语标志来确定动词的时态,在不同的语言环境中达到熟练掌握的目的.
