心水一版本参考答案及详
1.we( ) here at lunch time ; we were delayed at the airport,though
A.could be B.should be C.must have been D.would have been
答案：D
解题思路：would have done 本来可以做某事 .对过去事情进行说明时,无论用哪个情态动词,后面都应该使用have done 而不是动词原形,所以排除A和B.
对过去情况的肯定推测,使用must + have +done ,一定可以做某事.
2.why( )you be talking so loudly while others are studying?
_I am teribly sorry.
A.shall B.must C.will D.may
答案：B
解题思路：语气最强的是B项.
为什么别人学习时你说话这么大声?A项和C项中,C与you搭配,但时态不对,D意思不对
3.hellen( )have thought she had got well prepared for the coming exam,or she wouldn't have wasted
time watching TV,I suppose.
A.should B.can C.would D.must
答案：D

对现在情况的否定推测,使用cannot /can't+ V原形 ；对过去情况的否定推测,使用cannot /can't + have +done
这题考察“对过去情况的肯定推测,使用must + have +done .”
