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”。2. A. 此处can表示推测“可能”的意思；have to表示“不得不”，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，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。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“不应该”。22.
