题目内容
7.I'm glad you've come back from the United States.Please tell me how long you ____there.( )| A. | have stayed | B. | had stayed | ||
| C. | have been staying | D. | stayed |
分析 很高兴你从美国回来了.请告诉我你在那呆了多久.
解答 答案:A
there指的是美国,问这个人在美国呆了多久,因为他已经从美国回来了,have stayed 表示曾经在那里呆过,到现在仍然是存在的,没有终止的一个问题,所以用have不用had,用现在完成时,排除B.选项C have been staying 不适合,因为已经回来了,而且stay for some time是不可持续动词,只是表示一种状态而不是动作.D stayed表示过去式,很明显不适合,因为题目中要求的是意思是曾经呆过多久,用完成式.故选A.
点评 本题主要考查现在完成时的含义,表示过去发生或已经完成的动作对现在造成的影响或结果,其结构是:have/has+及物动词的过去分词.
