Answer 1

1.A 本句是虚拟语气和真实语气的混合，逗号前面那句是虚拟语气，后面那句是真实语气，所以选一般过去时。句意：（我要是早知道你在这等我，）我就来早一些了，但是我并不知道你一直在等我。事实上我并没有来早，但是不知道你在等我是真实的。
2.A 逗号前那句其实是if从句，用的是倒装结构，也可以是if she had found it
本句是对过去情况的虚拟，从句用过去完成时，主句用would+have done
3.A would rather 句后用动词原形表示虚拟
4.D it在这里是形式主语，真正的主语是后面的that从句，这也是虚拟语气的一个句型，但是要用过去式表示虚拟,并且be动词一律用were。还有行为动词的比如：It's time you went to bed.

Answer 2

第三题 应该选b would rather的用法,它何时用虚拟语气,何时不用？
would rather后接宾语从句，从句中用虚拟语气，指某人宁愿让另一个人做某事。若表示现在或将来要做某事，从句谓语动词用一般过去时，表示过去已经做的事，从句谓语动词用过去完成时。例如：
The manager would rather his daughter did not work in the same office.
To be frank,I'd rather you were not involved in the case.
若某人愿意自己做某事，would rather 后接动词原形，例如：I would rather stay at home today.
would rather ...than...中用动词原形，例如：I would rather stay at home than go out today

Answer 3

1 A
2 A
前两道题楼上的两位已经解释过了
3 C 此句意为“我宁愿你马上离开”，很明显，这是与现在事情相反的事情，用一般过去时。
4 C should be有竟然的意思，意为“她竟然这么不认真”

Answer 4

终于有题目了哈。
1 A know没有hadnt known的说法 所以选A
2 A 虚拟语态
3 B 又是虚拟语态
4 B 两个动词都是过去式

应该都是对的。
