答案及解析

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 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。

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

6. 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。

7. 选A。由于从句中的 spent 缺宾语，故应用关系代词(that)，而不能用关系副词。

8. 选C。in which case 在此相当于 and in that case。

9. 容易误选 A或B，想当然地根据空格前的逗号认为这是非限制性定语从句。其实此题应选D，逗号前是一个条件状语从句，逗号后是该状语从句的主句，that 在此代表前文所述的意思，用作主句的主语。

10. 选A。where 意为“在……的地方”，引导地点状语从句，不是定语从句。

11. 此题很容易按汉语意思误选A，其实应选C。whoever 引导的是让步状语从句，相当于 no matter who。

12. 选C。全句为强调句，被强调成分是 the boy (以及修饰它的定语从句who had been in prison)。

13. 选 A。注意不能选 D，因为动词 explained 缺宾语。

14. 选C。from whose efforts he still suffers 为修饰 a serious illness 的定语从句，whose 在定语从句中用作定语，修饰 efforts。

15. 选C。第一空填 which，指 the old building；第二空填 where，用以引导表语从句。

16. 选A。where 指“在……的地方”，用以引导地点状语从句。

17. 选A。wherever 意为“无论什么地方”。

18. 选 A。now that 为连词，用以引导原因状语从句，其意为“既然”，与since 同义。其中的 might as well意为“不妨”。全句意为“既然你得到一个机会，你不妨充分利用它”。

19. 选C。the first time 在此用作连词，用以引导状语从句。句意为“我第一次见到她就认为她很诚实”。

20. 选C。in case 意为“以防”。
