给讲一下，谢谢

Answer 1

1. B
如果后面是状语从句，则其时态为一般现在时，而不能是一般将来时（主将从现），由此排除引导状语从句的ACD；
B为同位语从句，即为句子主语The problem的同位语，解释其具体内容，其中whether的意思是“是否”。

2. C
答语为省略的强调句型，即其完整句子为：
It was at the department store ______ we uded to shop (that I got such a beautiful skirt).
这就说明______ we uded to shop为定语从句，修饰被强调部at the department store中的the department store.
很明显，该定语从句缺少地点状语at/in the department store，所以选入关系副词where.
如果选A that，即直接用强调句型，则答非所问（楼主自己翻译一下看看即知）。

3. D
定语从句，修饰句子主语A survey.
很明显定语从句缺少状语in a survey，即填入in which，也就是关系副词where.
此处where所表示的地点状语为引申含义。

Answer 2

A 除非
C 定语从句，本题易选A，把它当成强调句，这样就答非所问

C survey的 同位语从句，解释survey的内容

Answer 3

A 除非
C 从句为we used to shop at the department store
C 做survey的同位语从句
