告诉你一个工具吧,比在这里问人要管用的多,问题太长,大家就懒得答了.嘿嘿.查英汉词典吧,对比一下短语的意思,你肯定就会明白了.我觉得你之所以不明白应该就是不明白他们的意思吧?嘿嘿.
must have done 一定已经做了某事
should have done本应该做某事（实际上没做）
shouldn't have done 本不该做某事（实际做了）
could have done /couldn't have done 不太清楚,应该是could=may（我认为）无确切根据,所以不敢肯定
might have done/may have done…… 可能已经做了某事,只是时态不一样,might是过去时,may是现在时
need have done/needn't have done本来必须（不必）做某事,类似于should have done/shouldn't have done.

4.remain to be 是尚待……排除A B，剩下C，D。坐下用be seated ，所以选D
6.be busy with 是固定用法
8.fill是填满的意思，那么填满脑袋是主动，剩下B。C。to fill 表示将来或是目的，那么填满脑袋的工作是正在做的事情，所以选B
9.跟8一个道理啊，找到事情，事情作主语，那么就是被动，用做定语就写found啊。
10.跟前面的第二题一摸一样啊。
13.must have done 本必须做
should have done本应该做某事
shouldn't have done本不应该做某事
could have done本可以做某事
couldn't have done本不能做某事
need have done本需做某事 needn't have done本不必做某事
