B. which is a bad habit 非限制性定语从句.26. 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.27. 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.29. 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。29. A. 先行词gas被only修饰，关系代词要用that，而不用which。30. 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。31. 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。 32. A. 解释见35题。33. 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。 at, in和on表示地点时的区别1. at表示地点：（1）用于指较小的地方。如： I shall wait for you
