请教几道虚拟时态题。感觉很难的说！

1. You may prefer to travel by plane, but if the weather is bad, you might have to use that train.

答案是：D。可是我感觉没错啊。might 不是可以跟should, could, would一样用吗？

2. We should not wonder that their jaws fell open, I am sure you would too, if you had seen him when he arrived.

答案是：C。可是怎么改呢？would --> wouldn't? 可是后面是too不是either啊。

3. Did you expect Frank to come to the party?

No, but I had hoped_____.

(A) him coming                            (B) that he comes

(C) that he would come               (D) him to

答案是：C。我觉得没有一个对的。有wish/hope sb. would do sth. 这一说吗？好像它们只能跟过去式和过去完成式吧。

4. Many dead would now be alive if they had not attempted to return for something.

答案是：C。可是我觉得没有错啊。不是过去发生的动作用过去完成式吗？

1. 但是它时态不对，不是过去时。

2，would->should

3,C correct  你预料到frank会来这个party吗？ （过去时）不，但是我希望他会来（主句过去完成时，从句过去时）

4，C correct: 注意，attempt Vt. 这里的后+to ,所以这里的attempt不是动词，使attempted adj.

因此，had not attempted-> had not be attempted

1。might可不可以理解成是语气较弱的助动词而不是may的过去式呢？

3。attempt to do sth. 吧。这个好像是固定的搭配！

1.当然了，不认为是may的过去时，可是+have+...就成了过去时态了，所以时态不对。你看划线的部分是：might have to

2.attempt to 是“尝试”但是如果作"引诱",就不是这个结构了。
