题目内容
13.The project ______ last month but unfortunately it had to be prolonged(延长) because of the financial problem.( )A. | needn't have been finished | B. | shouldn't have finished | ||
C. | could have been finished | D. | must have finished |
分析 这个项目本来是可以在上个月完成,但是不幸的是,因为财政问题,它不得不被延期.
解答 答案:C 从but unfortunately it had to be prolonged because of the financial problem.可知这是对过去的虚拟,用could have done表示"本可以做却没有做",所以选C.
点评 情态动词表示虚拟是高考英语的重中之重,must have done表示过去肯定做了某事,shouldn't have done表示本不应该做而实际做了,needn't have done本没有必要做某事,而实际做了,诸如此类的短语都要进行重点记忆.
