Which _ do yourself?A. do you rather B. would you ratherC. will you rather D. should you rather答案与解析：1. D. 此处 can 表示 “能力” 。洛基英语 http:/ A. 此处 can 表示推测“可能”的意思；have to 表示“不
12、得不” ，强调客观情况。3. B.此处 can 表示允许，许可。4. D. 在表示能力时，can(could)和 be able to 在很多情况下能够互换，但在下列情况下只能 用 be able to: 位于助动词后；位于情态动词后；表示成功地做了某事。本题即属于 第三种情况。5. A. could have done 用于肯定句中表示本来能够做成某事但结果没能做成，含有遗憾的意 味，侧重有能力而没有能做成。6. B. may not 表示“可能不” ，表示不太确定的推测。7. B. mustnt 表示“禁止” ，may 表示不太确定的推测。8. D. 这里 must 表示必要性，意为“必须
13、，一定要” 。9. D. must have done 表示对过去发生的事情的肯定推测，意为“想必，准是，一定是”10. A. can/could not have done 表示对过去的否定推测“不可能做过” 。11. B. must have been doing 表示对过去进行时态或者过去完成进行时态的肯定推测。12. A. shall 用于主语为第一、三人称的疑问句中表示建议、征求对方意见时，其回答一般 用“Yes, you must.”或“ No, you neednt.” 。13. D.在主语为第二、三人称的肯定句中，shall 表示决心、许诺、命令等。14. D. should
14、指“应该” ，表示命令、劝告或建议等。15. C. 在某些名词性从句中，should 可以表示惊异、意外等情况，意思是“竟然” 。16. C. should /ought to have done“表示本该做某事却未做” ，其否定形式 shouldnt /ought not to have done 则表示“本不该做某事却做了” 。17. B. 本句表示本不该做某事却做了。18. C. will 与第一人称连用表示意愿、意志。其它选项则不能表示意愿。19. A. would 表示过去习惯性的动作。20. C. used to 表示“过去的习惯动作或状态（现在 已不这样） ” ，其后接动词原形。
15、21. C. 选项 A 表示“不能、不许” ；B 表示“不行、禁止” ；C 表示“不必、不需要” ；D 为洛基英语 http:/ 。22. C. neednt have done 表示过去本不必做某事而实际已做了某事，强调“不必要” ，其肯 定式 need have done 则表示过去本需要做某事而实际上未做。23. D. dare 作实义动词时其后的不定式可带 to，也可以不带 to，此句中的实义动词 dare 的 时态应为一般过去时态。24. B. had better 表示“最好” ，后接动词原形，其否定式为“had better not”.25. B. 能够表示“宁愿、宁可”意思的就只有 B。
