第一题,have thought否定应该是haven't thought .本来是否定的,所以不是应该用have they吗?
其它几道题目要选择的理由.
1.They can't have thought that i was at home then,B_?(在表示猜测时,反意疑问句中不能用情态动词)
a.did they b.have they c.do they d.was i

-really?and she is _ shorter of the two.记住：the *of the three,the four,the five,- --
a./,/ b.the,the c./,the d.the,/ the 比较级of the two
4.after the party ,shi found her nacklace gone ,and never_D again.（never found again 习惯用法,再也没有被找到===and was never found again.）
a.be found b.being found c.to found d.found错了，第一道。请比较和分析1 she must be at home now, isn't she（现在）2 she must have seen the film, hasn't she? （到现在为止）3 she must have seen the film last week, didn't she ? （在过去）4They can't have thought that i was at home then,_?（can't 指代的是现在，所以是have they?）haven't they 没有这个选项啊，而且答案是A这两句你碰到过吗？2 she must have seen the film, hasn't she? （到现在为止）3 she must have seen the film last week, didn't she ? （在过去）----she can't have seen the film, has she ?----- she couldn't have seen the film yesterday,did she?记住，时间状语决定反义疑问句的时态，如果没有明确的时间状语，就说明是现在时。一楼和五楼讲的错在哪表示猜测时，时间状语决定反义疑问句的时态，如果没有明确的时间状语，就说明是现在时。你们老师没有告诉你吗？1 she must have thoughtyou were there,____________? 请你做！反义疑问句2 she must have thought about you yeasterday_____________?
