Answer 1

1. C 看不出原材料
2.可以这么理解 I find what difficult (find sth +形容词)
3.in...way用。。。方法 介词后面不能跟that，还能跟wihch。
4.这题解释起来有些难。本人认为是因为前面提到了such这个词，所以它的情景就是用such表示如此（这样）的事情了，而不是all(所有；一切)。
5.其实这道题一看后面就知道用同一个时间连词了。
6.这是一道运用标准的虚拟语气句型了。if...+had done...，主句用...would/should/could/might+have done...。
7.insist that +should do should可以省略，insist on doing。
8.stop doing 停止做某事 stop to do sth停下来去做另一件事
