题目内容
3.We __________ our English teacher since he moved to Beijing.| A. | didn't hear from | B. | haven't heard from | ||
| C. | didn't receive | D. | haven't received |
分析 自从我们的英语老师搬到北京,我们没有收到他的来信.
解答 答案:B.根据关键词since he moved to Beijing.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,其否定形式是在助动词后面加not,缩写为haven't或hasn't;主语是we,助动词用have.hear from,收到某人的来信;receive,收到;hear的过去分词为heard,故选B.
点评 本题考查时态的用法,根据时间状语及标志词来确定动词的时态,在不同的语言环境中达到熟练运用的目的.
