答案与简析：
1. B 第一个定语从句的先行词those years是表示时间概念的名词，其后要用when 引
导定语从句，when在从句中作时间状语；第二个定语从句是非限制性定语从句，要用which
引导，which 指代整个主句，在从句中做主语。
2. C which 引导非限制性定语从句，指代整个主句所表达的内容，在从句中做主语。
3. C 从句中的谓语动词visited 在此是及物动词，要求所填的关系词是其宾语 ，要用
关系代词引导定语从句，当关系代词在从句中作宾语时可以省略，所以答案是C 。
4. A 当定语从句的先行词是the way （方式）时，引导定语从句的关系代词要用in which
或 that ，也可以省略关系代词，所以答案是A 。
5. D 当先行次被形容词最高级或序数词修饰时，引导定语从句的关系代词要用that 。
6. D 当先行词既有人又有物时，引导定语从句的关系代词要用that 。
7. D 当先行词是everything ，something ，anything ，nothing ，all ，none ，
little 等不定代词时，引导定语从句的关系代词要用that 。

8. C 当先行词被such 修饰时，引导定语从句的关系代词要用本题中的as 引导非限制性
定语从句，在从句中做主语。Such?as 为惯用法。
9. B as 引导非限制性定语从句，修饰整个主句，在从句中做主语。as引导的非限制性
定语从句总中可位 于句首、句中或句末，而which引导的非限制性定语从句不能位于句首，
只能位于句末。
10. A 在非限制性定语从句中，表示事物的关系代词只能用 which 。
11. B among 意思是“在??之中”，而one of 显然不符合题意，不能引导
非限制性定语从句，故答案为B 项。
12. B 关系代词as 在其所引导的非限制性定语从句中作主语。
13. B 从句子结构来看，此句应是非限制性定语从句，故答案只能选B 。

定语从句中作地点状语。
15. C关系代词as 引导非限制性定语从句，并在从句中作主语。
16. B 根据题意，pages 应是属于课本的，故应选 B 。
17. D 先行词father 是人时，关系代词不能用 which ，且引导先行词的关系
代词在从句中作主语，故选D 。
18. D 后面的句子不是前面句子的定语从句，不能作后面句子的任何成分，而是一个并
列句，故选 D 。
19. B 关系代词修饰前面整个句子，并引导非限制性定语从句，在从句中作主语成分。
