1、D

2、A

3、A。自己主动准备晚餐

4、A。还放在那里，对现在仍有影响

5、C。dare做情态动词时在否定或疑问句中可省去to

2选A，因为mustn't意为禁止，这里表示反问，不适合；don't you用在句子的主动词为do时（通常do省略，只有主动词）如：You like bananas,don't you?而这个句子的主动词为have，所以用haven't you
3.have sth. done意思是让别人为你做，这里have dinner prepared意为让找别人做饭，而不是自己做，不符题意
4.因为前面问你Where did you...它用助动词did问你，你就要用did回答，而不是have
5.dare not时dare相当于does not，所以不能加to，它在这里不是行为动词,而是情态动词

1.B 只有主句和从句的主语一样时,才能省略;这道题主句的主语是"the teather"而从句的主语很明显不能是"the teacher "所以不能省略 四个选项只有B没省主语

2.A must have done在肯定句中表推测，对过去的推测，反意疑问句用”didn't +主语”，若强调动作的完成，”haven't (hasn't)＋主语”
don't you用在句子的主动词为do时（通常do省略，只有主动词）如：You like bananas,don't you?

3.A have sth. done意思是让别人为你做，这里have dinner prepared意为让找别人做饭，而不是自己做，不符题意

4.C 第二个空就是陈述一般事实，不需要用完成时

5.C ”didn't dare ”dare是实意动词，应该是dare to do 但如果前面有do 或do 的任意一种形式如：did, done 要省略to
D项”dared not ”dare是情态动词
