　　2．关系代词that和which的用法区别

情况 说明 只用that不用which 先行词是不定代词或由不定代词修饰时 先行词是序数词、形容词最高级或被其修饰时 先行词被the very, the only等修饰时 主句是以which, what, who开头的特殊疑问句时 先行词既有人也有物时 两个定语从句中一个关系代词用which, 另一个要用that 只用which不用that 引导非限制性定语从句时 关系代词前有介词时 先行词本身是that时 　　

　　I have some books that are worth reading.

　　我有几本值得看的书。

　　This is the most interesting film that I've ever seen.

　　这是我看过的最有趣的电影。

　　This is the very dictionary that I want to buy.

　　这正是我想买的那本词典。

　　Which is the T­shirt that fits me most?

　　哪一件T恤最适合我？

　　Can you remember the scientist and his theory that we have learned?

　　你还记得我们学过的那位科学家和他的理论吗？

　　The reason for which he refused the invitation is not clear.

　　他拒绝邀请的原因不清楚。

　　三、"介词＋关系代词"引导的定语从句

　　有时从句中的介词可以提前到关系代词之前，形成"介词＋关系代词"结构，关系代词可以用which, whose, whom，不可以用that。其选择依据如下：

　　1．根据定语从句中动词或形容词等的习惯搭配。

　　I bought a great many books on which I spent all my money that I saved.

　　我买了很多书，这些书花光了我所有的积蓄。

　　2．依据与先行词的搭配。

　　This is the camera with which he often takes photos.

　　这就是他经常用来拍照的相机。

　　3．根据所表达的意义。

　　This is the pilot by whom my son was saved.

这就是救了我儿子的那位飞行员。
