1、定语从句一、概念：在复合句中，修饰某一名词或代词的从句叫定语从句。如：I want to marry a rich man. 定语I want to marry a man who is tall, rich and handsome. （从句谓语和先行词一致） 先行词 定语从句定语从句所修饰的词叫先行词；定语从句用关系词（_ _）来引导，关系词放在先行词与定语从句之间起连接作用，同时又作从句中的一个成分。1)关系代词：_2)关系副词：_二、关系词的用法：（一）关系代词的用法：1) who, whom, that这些词代替的先行词是人的名词或代词，在从句中作主语或宾语。例如：He is the

(四) 关系代词与关系副词的选择用关系代词还是关系副词引导定语从句主要看关系词在定语从句中的作用（即所担当的成分：如果缺少
8、主语或宾语时，关系词应该用which或that, 缺少时间状语、地点状语或原因状语时，才能用when, where或why）关系代词thatwhichwhowhomwhose指代对象人、物物人人人、物在从句中的成分主、宾主、宾主、宾宾定关系副词wherewhenwhy指代对象地点时间原因在从句中的成分状语状语状语Practice：1)This is a factory _ handbags are made.2)This is a factory _ makes handbags.3)I know a place _ we can have a picnic. 4)I know a place

10、意义就不完整。如：She has a son who is working at school.2非限制性定语从句只是对先行词作补充说明，没有限定作用，它与先行词的关系比较松散，因而不是关键性的，如果省略，原句的意义仍然完整。这种从句在朗读时要有停顿，在文字中通常用逗号与主句隔开。如：She has a son, who is working at school.引导非限制性定语从句的关系词有：who, whom, whose, which, when 和 where，不可以用that和why 3两种定语从句的内涵不同，限制性定语从句具有涉他性，而非限制性定语从句具有唯一性，这在理解和翻译时应
11、特别注意。试比较：She has a son, who is working at school. （只有一个儿子）=She has a son and he is working at school.She has a son who is working at school.（不止一个儿子）4. when和where既可以引导限制性定语从句，也可以引导非限制性定语从句。而why 只能引导限制性定语从句。四、注意事项1. 关系代词that，which 的用法(1)只用which，不用that的情况 (a) 在引导非限定性定语从句时。 The tree, which is four hundred years old, is very famous here. (b)介词后不能用that。 We depend on the land from which we get our food. We depend on the land that/which we get our food
