Answer 1

1.C 好像 她装作什么事都没有发生过。A没有好像的意思，而是作为，由于的意思

2.A 如何，他要如何处理它，还没人知道呢。 后面有个it，一般和How搭配连用的。

3.D of 是介词后面用宾格whom。B没有这样的搭配的。

Answer 2

1.act as...(演...角色)中 as是介词，之后不接句子，而as作连词时意思是：依照;当...时， 随着， 因为，虽然
as if或as though译为“好像，似乎”此题的从句部分是虚拟语气

2.根据句意可选用how/when/why之类的特殊疑问词，也可以用表“是否”的whether，因为是引导主语从句所以不能用if（if不引导主语/表语/同位语从句，呵呵受限制的还有其他情况）

3.定语从句中确实有时候who（主格）可代替whom（宾格），如：The lady whom/who Jack is talking with is my math teacher.但如果将介词提前，则只能用whom，表达为The lady with whom Jack is talking is my math teacher.此题就是因为of介词
