2. My sister met him at the Grand Theatre yesterday afternoon,so he______your lecture.
A. couldn’t have attended B. needn’t have attended
C. mustn’t have attended D. shouldn’t have attended
【解析】couldn’t have done: (过去)不可能做某事; needn’t have done:本来不必做某事;mustn’t have done:一定未做过某事： shouldn’t have done:本不该做某事。根据提供的情境My sister met him at the Great Theatre表明他不可能参加讲座。答案是：A。

4.I heard they went skiing in the mountains last winter?

A. may not be B. won’t be C. couldn’t be D. mustn’t be
【解析】may not be : 可能不是;won’t be：不会是;couldn’t be：不可能是; mustn’t be ：一定不是。根据提供情境there was little snow 说明山里滑雪是件不可能的事，may not 语气不如couldn’t强。答案是：C。
分析：高考对表示推测的情态动词集中在must, can, could, may, might上，准确掌握它们使用的场合，是解决问题的关键。Must 用于肯定陈述句，表示肯定推测;can, could用于疑问或否定陈述句，表示可能性推测;may, might用于陈述句，表示可能性推测;用于否定陈述句中，can’t (不可能)的语气比may not(可能不)强。此外，还要注意有对过去和对现在两种情况的推测,对过去推测用情态动词+have done ，对现在推测用情态动词+ 动词原形。

7. There was a lot of fun at yesterday’s party. You______come, but why didn’t you?
A. must have B. should C. need have D. ought to have
【解析】ought to have done 表示本来应该做某事而实际没做，should do 表示现在应该做某事，与题中 at yesterday’s party 表示的时间不一致。所以选D。

9.Oh, I‘m not feeling well in the stomach. I______so much fried chicken just now.
A. shouldn’t eat B. mustn’t have eaten C. shouldn’t have eaten D. mustn’t eat
【解析】该句所表达的意思是刚才我不因该吃那么多炸鸡，而实际上是吃了那么多，可以判断用shouldn’t have eaten. 答案是 C。
分析：高考对情态动词表示虚拟‘用法，表示与过去事实相反的情况。近几年高考，主要侧重should (not)have done 这一句式上，表示本来不该做却做了或本来该做却未做的事，在复习时，还应关注其它几种虚拟形式，如need (not)have done 表示本来需要做而未做或本来不需要而做的事等等，以做到有备无患。
