C。could在此表推测，意为“可能”。虽然can和should也可表推测，但前者主要用于否定句或疑问句，一般不用于肯定句；而后者由于语气太强(过于肯定)，在此与语境不符。3. D。could在此表推测，意为“可能”。虽然can也可表示推测，但由于它通常不用于肯定句，所以被排除。注意，此处要选D而不选B，因为它是表示对过去情况的推测，即“过去”他们忘记打电话，所以导致大家现在很着急。4. D。第一空填must have opened，表示对过去情况有把握的肯定推测，其意指一定发生了某情况；第二空填couldn’t have escaped，表示对过去情况的否定推测，其意指不可能发生了某情况。全句意为：一定是有人打开了笼子——因为狮子是不可能自己跑出来的。5. B。根据前面一句的过去时谓语可知，此处谈的是过去情况，所以选might have been killed，表示过去可能发生而实际上没有发生的情况，注意此时不能用may接完成式来表示，所以不能选D。6. C。根据答语No, there’s no need可知，空格处应填must，意思才通顺。7. B。根据句意可知，两者的答案完全一样，说明肯定有一个人抄袭了另一个人的；另外，从时间上看，肯定是先有抄袭的行为，后才有答案一样的结果，所以此处用“must+完成式”的结构。8. B。can表示推测时通常只用于否定句或疑问句，很少用于肯定句。但有两种情况是例外（即可用于肯定句）：一是表示纯理论上的可能性，二是表示“有时”。如：Even experienced teachers can make mistakes. 即使是有经验的教师也可能出错。She can be very unpleasant. 她有时很令人讨厌。9. D。may和might后可接副词well加强语气，意为“很可能”。如：It may well be true. 那很可能是真的。 He may [might] well find that the course is too difficult. 他很可能觉得这门课太难。10. B。由于是谈论上周的情况，所以空格处应用“情态动词+完成式”，故可排除A和C；又因为can表推测时通常只用于否定句或疑问句，一般不用于肯定句，故可排除D。注意：can表推测时不用于肯定句，但could可以。又如：I could have lent you the money. Why didn’t you ask me? 我本来可以借这笔钱给你的。你为什么不向我提出呢? 11. B。may在此表推测，意为“可能”，又如：It may sound strange, but it’s true. 这件事可能听起来很怪，但它是真的。12. B。做此题关键是要注意破折号后面的语境。you had lunch only two hours ago的意思是“你两个小时前才吃过中饭”，据此可知，你现在“不可能”就饿了，故用can’t。 上一页[1][2] 说明:引用此文
