1．(2011?天津质检)My suggestion is that you________much meat.
A．wouldn’t take             B．shall not take
C．not have                 D．won’t have
解析： 当suggest 或suggestion 为“建议”的意思时，与其有关的从句就要用虚拟语气，即“should＋动词原形”，should 可以省略。
答案： C
2．(2011?安徽芜湖调研)If human beings had been a bit less greedy and cruel，more birds and animals________dying out.
A．ought to avoid              B．could have been avoided
C．should have avoided         D．might have avoided
解析： 句意为：如果人类少点贪婪少点残忍，更多的鸟类和动物就有可能免于灭绝。这里考查的是对过去情况的假设，从句用had done，主句用would/could/might have done。avoid “避免”，其后接doing 时没有被动语态。
答案： D
3．(2011?哈尔滨检测)________anyone call，please tell him I’m not free.
A．Must               B．Can
C．May               D．Should
解析： 本题考查情态动词用法。句意为：如果有人给我打电话，就告诉他我很忙。第一个分句是省略了if 虚拟条件句，补充完整为：If anyone should call，please tell him I’m not free.当if 省略时，句子要倒装，故D项正确。
答案： D

A．came                      B．had come
C．would come                D．would have come

—I________，either，if my mother hadn’t reminded me.
A．wouldn’t              B．wouldn’t have

答案： B

答案： D

答案： B
