题目内容
5.-Why don't you want to see the dolphin show?-I it before.
| A. | see | B. | saw | C. | will see | D. | have seen |
分析 -你为什么不去看海豚表演啊?
-我以前看过.
解答 答案:D 根据before可知,动作已经完成对现在造成一定的影响,表示"以前看过,现在不去看了",所以用现在完成时态,现在完成时态的结构为have/has+动词的过去分词,主语是I,助动词用have,故选D.
点评 判断动词的时态,要通过所给的时间状语、提示词或语境去判断动词存在的状态,本题注意上下文的关系.
