引导定语从句的关系代词有：that（指人或物），which（指物），who (指人）。指人时可用that或who ；指物时可用that 或which ；但有时只能用that，不能用which。常见的情况有下列五种：
1） 当先行词是：all , any , anything , everything , nothing the one, much, few, little或被它们修饰时。例如：
Is there anything that I can do for you ? 有什么可以为你做的吗？
All that can be done must be done . 凡是能做的都必须做。 2）当先行词被形容词的最高级或序数词修饰时。例如： That is one of the most interesting books that are sold in the bookshop .
那是这家书店出售的最有趣的书之一。

3）当先行词有：the only , the very , the same , the last 等修饰时。例如：
My necklace is not the only thing that's missing . 我的项链不仅是丢掉的东西。
4）当主句以who或which开头时，定语从句中引导词用that ,不用which 或 who 。以避免重复。例如：
