语法总结
非限定性定语从句
非限定性定语从句的作用是对所修饰的成分作进一步说明(注:通常和主句间用逗号隔开,不受主句句子结构的影响,将从句拿掉后其他部分仍可成立)
限制性定语从句与非限制性定语从句的六点区别
区别一:形式不同
限定性定语从句主句和从句之间不用逗号隔开,口语中使用时也不停顿;而非限定性定语从句与主句之间通常有逗号隔开,口语中使用时有停顿。
区别二:功能不同
限定性定语从句用于对先行词的意义进行修饰、限制和识别,如果去掉,就会造成句意不完整或概念不清;而非限定性定语从句用于对先行词起补充说明作用,如果省略,句意仍然清楚、完整。如:
People who take physical exercise live longer. 进行体育锻炼的人活得长些。(若把从句去掉句子就失去意义)
His daughter, who is in Boston now, is coming home next week. 他女儿现在在波士顿,下星期回来。(若把从句去句子意义仍然完整)
区别三:翻译不同
在翻译定语从句时,一般把限定性定语从句翻译在它所修饰的先行词之前,而把非限定性定语从句与主句分开。如:
He is the man whose car was stolen. 他就是汽车被窃的那个人。
I’ve invited Jim, who lives in the next flat. 我邀请了吉姆,他就住在隔壁。
区别四:含义不同
比较下面的两个句子:
I have a sister who is a doctor. 我有一个医生的姐姐。(姐姐不止一个)
I have a sister, who is a doctor. 我有一个姐姐,她是当医生的。(只有一个姐姐)
区别五:先行词不同
限定性定语从句的先行词只能是名词或代词,而非限定性定语从句的先行词则可以是名词或代词,也可以是短语或句子;另外,当先行词为专有名词或其他具有独一无二性的普通名词时,通常要用非限制性定语从句,而不用限制性定语从句。如:
Peter drove too fast, which was dangerous. 彼得开车很快,这是很危险的。(which指drive too fast)
He changed his mind, which made me very angry. 他改变了主意,这使我很生气。(which指整个主句)
区别六:关系词不同
关系词that和why可用于限制性定语从句中,通常不用于非限制性定语从句;另外,在限制性定语从句中,关系词有时可以省略(参见本章有关内容),而在非限制性定语从句中关系词一律不省略。
