Question

英语求教，请详细教我为什么，谢谢了

25. I will give you such information _______ will help you.
A. which B. that C. as D. what
30. Did they find they went back________ ?
A. where had they been B. where were they C. where they had been D. where they were
31. To get the job started, ______ I need is your permission.
A. only what B. all what C. all that D. only that

Answer 1

25.B.that 做后面整个句子的主语，引导一个定语定语从句修饰前面的名称information。表示是可以帮助你的信息。
30.C.整句话的意思是:他们发现了他们又回到了他们原来所在的地方吗?他们发现用的是Did和went说明是过去，那么后面是“原来所在的地方”在“他们发现”这个动作之前，就是过去的过去就是过去完成，只有A或C可选，由于where引导的一个地点状语从句，所以从句要用陈述语序，所以选C.
31.C. 开始工作，我所需要的只是你的允许。To get the job started, all that I need is your permission. all that 中all是先行词，that在后面的定语从句中做宾语，整个从句修饰all。其实all that 就相当于what， what i need 我所需要的。

Answer 2

25. A, which
30. C, where they had been
31. A，only what

Answer 3

C such... as
C 主句时代为过去时 宾语从句过去完成时，他们有没有发现又回到了原来的地方。
C all that 是搭配
