在英语语法运用中，什么时候用限制性定语从句，什么时候用非限制性定语从句，谢谢

什么时候该用限定性定语从句什么时候用非限定性从句~

1.限制性定语从句修饰的是先行词：He sings the song which I don't like.定从修饰的是song,表明我不喜欢的是这首歌.
2.非限制性定语从句修饰的修饰的是句子：He sings the song,which I don't like..定从修饰的是逗号前面的句子,表明我不喜欢的是他在唱这首歌,并不是这首歌本身的原因.

限制性定语从句不用逗号与主句分开，对所修饰的词起特指或限定的作用，去掉后意思不完整或不太清楚。翻译成中文时，一般把定语从句翻译在先行词之前。
eg. This is the man who helped me. 这就是帮助过我的那个男人。（如果缺乏了从句则主句意思不明确）
I was the only person in our office that was invite to the palace ball. 我是我们办公室里唯一一个被邀请到宫殿厅的人。 非限制性的定语从句和主句之间往往用逗号分开，只对被修饰的词语或主句起补充说明的作用，去掉后对句意影响不大。翻译时通常把定语从句翻译在先行词后边，作为附加说明。
eg. I have two sisters, who are both doctors. 我有两个姐妹，她们都是医生。（除去从句也可以表达清楚）
Last Sunday they reached Shanghai, where a meeting was holding. 上个星期天他们到达了上海，那儿正有一个会议召开。

怎样区分限制性定语从句与非限制性定语从句

限制性定语从句

非限制性定语从句

形式上

不用逗号和主句隔开

用逗号和主句隔开

意义上

是先行词不可缺少的定语，起“指定是哪一个”的作用，去掉后句意不完整

是对先行词的补充说明，删除后句子意思仍完整

译法上

翻译成先行词的定语，“……的……”

通常翻译成主句的并列句

关系词的使用上

A. 作宾语时可省略； B.可用that; C. 可用who代替whom；D.可用why

A. 不可省; B. 不用that; C. 不用who代替whom; D. why要换为for which

考点1. 限制性定语从句和非限制性定语从句的区别
A. 限制性定语从句紧跟先行词，与先行词之间一般不加逗号，仅修饰先行词，可以由关系代词、关系副词或that来引导。非限制性定语从句仅作补充或说明，用逗号与主句隔开，既可修饰先行词，又可修饰整个主句，不可用that引导。如：
① This is the house which we bought lastmonth.
这是我们上个月买的那幢房子。（限制性）
② The house, which we bought last month, isvery nice.
这幢房子很漂亮，是我们上个月买的。（非限制性）
③ I lost mymoney that day, for which I had to walk home. (非限制性，for which不能换为why，which代指前面 “I lost my money that day.”这句话)
④ He met with a pretty girl in the park, whomhe fell in love at first sight. (非限制性，whom不能换为who)
B. 当先行词是专有名词或由物主代词和指示代词所修饰时，其后的定语从句通常是非限制性的。如：
① Charles Smith, who was my former teacher,retired last year.
查理·史密斯去年退休了，他曾经是我的老师。
② My house, which I bought last year, has gota lovely garden. 我的房子，去年买的，带着个漂亮的花园。
③ This novel, which I have read three times,is very touching. 这本小说很动人，我已经读了三遍。
