定语从句总结

1. 定语从句: 1) 定语从句的定义 在复合句中， 修饰名词或代词的从句叫做定语从句。被定语从句所修饰的词叫先行词。引导定语从句的词叫关系词。关系词包括关系代词 who(宾格 whom,所有格 whose),that, which 和关系副词 where, when, why 等。 The boy who is wearing a black coat bought a dictionary yesterday. The noodles that（which） my mother cooked were delicious. The school where I learned judo was very large. I remember the day when our band was formed. I don’t know the reason why she got so angry this morning. 2) 定语从句的种类：定语从句可以分为限定性定语从句和非限定性定语从句。 (1)限定性定语从句：它是先行词在意义上不可缺少的定语，如果去掉，主句的意思就不完整或失去意义。这种从句与主句的关系十分密切，书写时不可用逗号分开。如果关系代词在限定性定语从句中作宾语，关系代词通常可以省略。 Do you know the girl who just came in? Shanghai is a city（that）I’ve always wanted to visit. Her sister married a man (who/whom/that) she met on a plane. The time when I first met Mr. White was a very difficult period of my life. (2)非限定性定语从句：它只是对先行词作附加补充说明，如果去掉，主句的意思仍然清楚完整。这种从句与主句的关系不是很密切，书写时往往用逗号分开。非限定性定语从句一般不用 that 引导，而且不可以省略关系词。 The old woman, who lives on her own, has a cat for company. Lori is going to marry Mark, whom she does not love. Beijing, which is the capital city of China, is a very beautiful city. 3) 关系代词的用法：在定语从句中， 关系代词起着连接主句与从句，指代先行词和在从句中作句子成分的三重作用。关系代词的选用取决于主句中的先行词以及关系代词在从句中作何种成分。 一． 关系代词 w ho, w hom 的用法 （1） who 可以代替人（即它的先行词必须是人），在从句中担任主语，往往也可以代替在从句中担任宾格的 whom,但它的前面不能有介词，如果带介词则必须用宾格 whom，即“介词 +whom”.
