【答案详解】
1. 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. 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)
3. 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。
4. C。此题考查whatever= anything that，相当于一个定语从句。选项A在that前加anything, 其他选项不符合题意。
5. B。因同位语从句中不缺任何句子成分，意义非常完整了，所以用that。
6. A。在宾语从句中作定语，表示“多么”，只能用what。
7. B。that引导的从句作word的同位语。
8. B。在同位语从句中作主语只能用what。因为that在同位语从句中不作任何句子成分; which, as不能引导同位语从句。
9. A。因宾语从句中不缺主语或宾语，排除连接代词what或who; that没有任何意思，不作任何句子成分，why意为“……的原因，为什么”，在从句中作状语; 由wrote an article on (写了一篇关于……的文章)可知选why。
10. C。因选项B和D不能作定语，应排除; 根据语境要用whatever(=any任何)，而不用whichever(=the…that………的那个……)。
11. A。that在此引导同位语从句，修饰chance，又如：There was a chance that my letter would arrive in time. 我的信有可能准时到达。
12. C。根据句意，空格处应填一个表示“是否”的词，但在A和C两个表示“是否”的选项中，if不能用于介词后，故选C。
13. A。what在此引导主语从句，意思上相当于the thing that。
14. D。从句意上看，应一个表示“无论哪一个”的选项，因此B和D比较合适，但No matter which只用于引导状语从句，不用于引导名词性从句，故不能选B。
15. D。what在此引导宾语从句，其中宾语从句中的should后省略了动词do。
16. D。what在此引导表语从句，同时what在表语从句中用作动词did的宾语，其意相当于the thing that。
17. C。空格处填的是一个宾语从句，用作动词wonder的宾语。按英语语法，名词性从句(当然包括宾语从句)一律使用陈述句词序，不用疑问句词序，故可排除B和D。至于A，有两个错误，一是how much不宜直接修饰cost，二是句中的用they are也用得不妥。
18. B。第一空填what，用以引导宾语从句，用作介词of的宾语，其中的what在从句中用作动词have的宾语; 第二空填that，用以引导定语从句，修饰先行词something。
19. B。what在此引导主语从句，句首的it为形式主语。
20. C。how在此表方式，其后的it指前面提到的情况。全句意为：这儿的海滨每年夏天都要吸引许许多多的游客，这都是这儿温暖的阳光和柔软的沙滩的功劳。
