题目内容
7.Most of my classmates have had the experience of taking a plane,but I ____.( )| A. | wasn't | B. | haven't | C. | won't |
分析 我的大部分同学都已有了坐飞机的经历,但是我还没有.
解答 答案:B wasn't是was not的缩写;haven't是have not的缩写;won't是will not的缩写.根据"my classmates have had the experience"可知用的是现在完成时,其构成是:have/has+过去分词.所以空格处要借助助动词have来构成否定形式,故选B.
点评 英语中有许多缩写形式,首先要明白这三个缩写形式的表示的时态,然后根据具体的题意做出正确选择.
