题目内容
19.Wait a moment.The director _____ her assistant pick up some sandwiches for the meeting.( )A. | has | B. | has had | C. | had had | D. | was having |
分析 请稍等一下,主任已经让她的助理去拿些三明治了.
解答 答案:B
根据句意可知,此处表示过去发生的动作对现在产生的影响或造成的结果即:助理现在不在这里或者是已经有人去拿三明治了,就不用再派其他人去拿了;故用现在完成时,故选B.
点评 本题考查了现在完成时强调"影响性"的用法;现在完成时除了强调动作的持续性以外,它还强调过去的动作对现在产生的影响以及造成的结果;例如:I have already seen the film.我已经看过这部电影了.(对现在的影响是:我知道电影的内容);I have lost my key.我把钥匙弄丢了.(造成的结果是:我进不了门了.)
