参考答案及解析
41. A. what happened是宾语从句. all 之后that he knew是定语从句.先行词是all，所以关系 代词只能用that.
42. D. years是表示时间的名词，用when引导定语从句，是因为when在从句中作时间状语.第二个 空选用which，引导一个非限制性定语从句.
43. C. 本句话的定语从句是who own cars. 其先行词是people，因此，定语从句的谓语动词要用 复数的own。本句话主句的主语是The number of指？..的数目，是单数概念。因此 ，主句的谓语动词要用is。
44. D. that followed是定语从句，关系代词that在从句中作主语。
45. A. 先行词gas被only修饰，关系代词要用that，而不用which。
46. B. through which引导定语从句，through which即through the hole，在定语从句中作状语 。What引导的是see的宾语从句，并作从句的主语。
47. B. 为便于理解，改写本句话：This is the school that some Germanfriends visited last week. 不难看出，作表语的the school是先行词。that引导了定语从句，因为that同时又作visited 的宾语，所以被省略了。其它选项结构不对。
48. A. 解释见35题。
49. C. 因为是two ballpens， 并且定语从句的谓语writes是单数概念。因此，C是正确选项。
50. B. 本句话中，主句的主语是all，为抽象概念。因此，其谓语应用单数的has been。关系代 词that引导定语从句，并在从句中作主语
