D情态动词加完成式表示对过去情况的推测，在疑问句中表示推测只能用can。4. B 表示“本来不必做某事但却做了”，用needn’t加完成式。5. D needn’t不必；may加完成式表示对已发生事情的猜测，意为“可能已经……”。6. C may / might as well 是固定结构，意思是“还是 / 还不如……的好”7. C must在问句中意为“必须”，在答句中意为“硬是要”“偏要”。8. C don’t have to=needn’t不必。9. A would表示过去反复发生的动作，现在可能仍然在进行；used to 表示过去常常，但现在已经不再发生的动作。10. B shall可在任一人称的陈述句中表示说话人或作者的允诺、决心、警告、命令、恫吓、强制等。11. B could与完成式连用表示“本来可以做某事但却未做”，是对过去未实现动作的遗憾。12. C can与感官或知觉的动词see, hear, understand, imagine等连用，在此句中可译作“可以”，有时不必翻译。13. A ought to / should与完成式连用表示“本来应该做某事但却没做”，对其一般疑问句的简短回答是ought to / should have。14. C will表示某种倾向或目前的习惯性，意为“总是，惯于”。15. D could have done表
