Answer 1

1.have difficult in doing sth 是固定搭配！
2.have let make 等使役动词后面一般接的是动词原形
3. 记住前有do，后无to。but前有实意动词do的某种形式，后面就没有to.你看这句话前面没有do，就得有to
4.ought to=should 也就是说ought to 可以看成情态动词 ought不是情态动词
5.这里表示的是那个目击者没有看到，而不恳切的回答！
6.选D，参见第二个！
7.regret doing
8.be made to do

Answer 2

1. have difficulty in doing sth.干某事有困难
2.have sb do sth. 4.ought to do 是固定搭配 5. 若是D的话，从句没有主语
6.你可以把have的一些用法重新复习一下 7.regret doing sth.后悔做了某事，regret to do sth.后悔没做某事 8.这个我还真不好解释···是种语感

Answer 3

第五题5. the witness claimed _____a man in the party,这是完整的句子claim to do sth.这是固定短语申称做某事，不能用that引导的定语从句，,除非改作the witness claimed that he has seen a man in the party.

Answer 4

不定时表示将要发生，完成时表示已经发生
