答案

if anyone happens to drop in while i am out,him or her leave a message.
A.have B.get C.ask D.tell 这道题目选择A,可是我觉得 C.D都可以讲得通
只有A才能用成：have sb do sth.
CD都是：ask/tell sb to do sth.
2.the bus driver insisted that he at a normal speed and therefore for the child's death.A.drive;not answer B.was driving;shouldn't answer C.should driver D.drove ;shouldn't answer.答案是A,但是我觉得主句有insisted 应该是过去时为什么不选D呢
insisted在这句里是“坚持要求”的意思,后面的从句一定要用虚拟语气,即：should do结构,should 可以省略.如果它译成：“坚持认为”,就不用虚拟语气,如：
He insisted(坚持认为) that he hadn't done anything wrong and insisted(坚持要求) that he should be set free at once.
3.the bank is reported in the local newspaper in broad daylight yesterday.A.to be robbed B.to have been robbed C.having been robbed 答案是B,句中有yesterday 我觉得应该用一般过去式,为什么答案却是用现在完成时表被动呢
这是个固定的句型结构：主语+be done + to do..如果不定式的动作发生谓语动词之前,那么要求后面的不定式用它的完成式：to have done.如：
The computer is said to have been invented many years ago.据说电脑在很多年以前就被发明出来了.发明这个动作发生在“据说”这个谓语前,用了完成式,同时它又是被发明,又用了完成式的被动式.to have been done.
如果不定式的动作不发生在谓语之前,一般用不定式的一般式,即：to do.如：
He is said to be honest.据说他这个很老实.
其实,这个结构是由另一个结构转换来的,你应该看过：
It is / was done that 主+谓.
It is said that he is honest.
It is said that the computer was invented many years ago.
