题目内容
7.--He promised to come yesterday but _______.--Be forgiving.He could have been caught by something unexpected( )
A. | didn't | B. | hadn't | C. | hasn't | D. | wasn't |
分析 --昨天他承诺要来,但是他没来.
--原谅他吧,他一定是被某些没预料到的事情困住了.
解答 答案:A,考查谓语动词的时态,根据语境是指昨天承诺来但没来,表示过去的动作,因此使用一般过去时,句子的完整表达为but he didn't come,因此使用其省略形式but didn't,其他选项均不符.
点评 考查谓语动词的时态,应根据语境进行判断.
