【答案与解析】

1. 选D。what made matters worse 是主语从句(注意其后有谓语动词was)，相当于 the thing that made matters worse。

2. 选A。what 引导的是表语从句，相当于 the thing that it takes to do anything well。

3. 选C。that 引导的是一个主语从句，句首的it为形式主语。

4. 选 C。答句为省略句，其完整形式为 I was trying to prove to the police where I was last night，在此 where 引导的是一个宾语从句。类似地，下面选 C：

_______ made her struggle to become an artist so hard? ______ she was a woman.

A. What, What B. That, That

C. What, That D. That, What

5. 选D。what 引导的是表语从句，what 在此相当于 the things that。

6. 选 C。句首的 it 是形式主语，空格处所填词用于引导主语从句。由于该主语从句中又缺主语，故排除A、B、D。(注意：不能选 A，因为 that 引导名词性从句时不能充当句子成分)

7. 选 A。第一空填 what，是因为该主语从句中的动词 understand 缺宾语;why 和 because 均可引导表语从句，其区别是： why 引导表语从句强调结果，because 引导表语从句强调原因。句中空格后文表明的是结果，故用 why。

8. B。what 在此引导主语从句且在从句作宾语，它相当于 the thing that。

9. B。两空均填 what，均用于引导宾语从句，因为两个宾语从句中的动词 said 和do 均缺宾语，而在各个选项中只有 what 可用作宾语。

10. 选 A。what 引导宾语从句。由于动词 wants 缺宾语，所以填 what。句意是：当你找工作面试回答问题时，请记住这条黄金定律：永远给予对方确实想要的东西。

11. 选 A。I can to save them 为 I can do to save them 之略，此句中的 do 缺宾语，故选 whatever。

12. 选 B。that 在此引导主语从句，无词义，也不充当句子成分。注意不要根据中文意思选 D，因为 because 不用于引导主语从句。

13. 选 C。两个空格处均为引导宾语从句的引导词，而四个选项中两者可引导宾语从句的只有 C。

14. 选 B。比较 Thats why 与 Thats because：前者用于强调结果，后者用于强调原因。如下面一题选 D：

I got wet all through. _______ I had neither a raincoat nor an umbrella.

A. Its the reason B. Thats why

C. Theres why D. Thats because

15. 选 D。由 is worth praising 这一谓语可知前面是主语从句，排除不能引导从句的 B 项和 C 项;whoever 引导主语从句表示任何的人，在此它相当于 anyone who。

16. 选 A。how 引导主语从句，that 引导同位语从句。
