1.Noticing a body fall off his bicycle,Mike ran over _____if he was hurt.
A.seeing B to see C saw D seen
2.Stand over there,____you will get a better view of the whole city .
A or B though C but D and
3.—Lily hasn't come back yet.
--Well,where____she have gone on such a night?
A must B would C could D will

1、B 这是一个非限定性定语从句,前半句是从句,后面是主句.做题时只看后面就可以了,接下来就简单了吧!
2、D 这是一个祈使句,一般有or和and 连接,又由于前面和后面是一种递进的关系,所以用and连接
3、B could have done表示本可以做某事却没有做,所以排除.没有will have done 的形式.must have done表示一定做了某事,语义不符.翻译：Lily还没回来.是啊,这样的晚上她会去哪儿呢?
再问： would have done 是什么意思
再答： “would+have+done”虚拟语气，表示对过去事情的假设，意思是“可能会做”。 1. I would have told you all about the boy's story, but you didn't ask me. 我本来会告诉你这个小男孩的故事，但是你没有问我。 2. Without your help, I wouldn't have achieved so much. 没有你的帮助，我是不会取得如此大的成绩。 “could+have+done”是虚拟语气，表示对过去事情的假设，意思是本来能够做某事而没有做。 He could have passed the exam, but he was too careless. 本来他能够通过考试，但是他太粗心。请看相关知识点：一、 “must+have+done”表示对过去事情的肯定推测，译成“一定做过某事”，该结构只用于肯定句，不能用于疑问句。 1. It must have rained last night, for the ground is wet. 昨晚一定下雨了，因为地面还是湿的。 2. You must have been mad to speak to the servant. 你和仆人说话，一定是发疯了。
