30、，不能用于否认句和疑问句中。2. C。此题考查以情态动词提问的一般疑问句的答复。在英语中，以某些情态动词提问的句子，出于礼貌委婉或句意的需 要，答复时，要换用另一个情态动词。在答复must开头的一般疑问句时，肯定答复用must，否认答复用neednt或dont have to；在答复may开头的一般疑问句时，肯定答复用may，否认答复用mustnt；在答复need开头的一般疑问句时，肯定答复用must，否认答复用neednt。3. B。根据题意，此处需要表示“推测的否认结构，故cant为正确答案。4. A。这是一个省略句，couldnt have done表示对过去发生的动作的否认推测，意为“

31、不可能。5. B。这是一个综合题。此题so that后的目的状语从句中的谓语动词要用“情态动词 may / might / can / could + 动词原形。When to expect us表示“我们什么时候可到达。“疑问词+不定式结构在句中作know的宾语。6. B。由sometimes可知，此处应用表示可能性不大的情态动词，即may。7. B。由后句可知，这是对过去发生的事情的肯定推测，故B项正确。8. B。but for的意思是“要不是，语法功能上等同于if 引导的否认虚拟条件句，因前句中How dangerous it was可知应与过去事实相反。9. C。mustnt表示“不准

32、许，may表示可能性，所以C正确。10. C。句意：她或许到过那里，或者。or . 是重要的信息，说明还有其他的可能性。A的说法太绝对，与or . 提供的信息冲突。11. A。must表示的把握最大，may表示有可能，need不表示推测，will表示将来。根据句意可知A正确，说明对对方的不理解和责备，语气比拟坚决。12. C。shouldnt have done 表示“本不该做，但实际上却做了。13. A。疑问句中可以用can, 肯定句用must。14. B。will + have done，表示对将来必然进程的猜想。15. A。should 表示主观性猜想，译为“应该。 16. C。cant

33、 表示否认的猜想，侧重于主观判断，译为“决不会；不可能。 17. D。should表示劝告某人应该做某事。 18. A。need引导的一般疑问句，肯定回容许用must。19. A。Shall I . ？是征求对方意见时常用的句型。二、强化练习1) 选择填空1. I didnt see her in the meeting room this morning.

53、两种情况：对现存状态现在的事实进行推测时，反意疑问句中动词用其一般现在形式。对过去发生的事情进行推测时，假设有表过去的时间状语，反意问句用动词的过去式。30. C. neednt have done表示“过去不必做而做了某事，假设表示“不必做某事且实际上未做“那么用didnt / dont / doesnt need to.31. D. A表示“本能够，B, C表“本应该。32.
