13、掉它主句意思往往不明确; 非限制性定语从句 是先行词的附加说明,去掉了也不会影响主句的意思,它与主句之间通常用逗号分开. This is the house which we bought last month. 这是我们上个月买的那幢房子。 (限制性) The house, which we bought last month, is very nice.这幢房子很漂亮,是我们上个月买的。 注意:注意:1) 当先行词是专有名词当先行词是专有名词或其他具有独一无二性的普通名词或其他具有独一无二性的普通名词或物主代词和指示代词所或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修饰时

14、,其后的定语从句通常是非限制性的。 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。 My house, which I bought last year, has got a lovely garden. 我去年买的的那幢房子带着个漂亮的花园。 Her father, who has a lot of money, wishes her to study abroad. 她父亲很有钱, 希望她出国学习。 This novel, which I have read three t

(1)as 引导的从句可以放在主句之前,而

18、which 引导的从句只能放在主句之后。 They are hollow, which makes them very light. As is known to all, Taiwan is a part of China. (2)从意义上讲,which 指前面主句的内容;而 as 指代的是作为一般人都知道的常识性的 东西,因此常译成“就象 那样”。 (3)as 引导的非限制性定语从句表示积极的意义,与主句是顺理成章的关系,绝不能与之 矛盾。若非限制性定语从句表示消极的意义,则只用 which。如: He has succeeded in his career, as / which we

19、all hope. 他在事业中成功了,这正是我们大家所希 Her grandma died last week, which made her very sad. 她的奶奶逝世了,这使得她很悲伤。 (4) 当非限制性定语从句的引导词前面有介词时,只能用 which, 而不可用 as。如: He has a new computer, for which he paid nearly ten thousand Yuan.

23、代词均不能省略。 介词的确定要遵从“一先,二动,三意义“的原则。 ”一先“根据先行词的某种习惯搭介词的确定要遵从“一先,二动,三意义“的原则。 ”一先“根据先行词的某种习惯搭 配确定介词; ”二动“根据定语从句中动词所修要的某种习惯搭配确定介词; ”三意义“根配确定介词; ”二动“根据定语从句中动词所修要的某种习惯搭配确定介词; ”三意义“根 据从句的意义来确定介词据从句的意义来确定介词. _which I spent 5 yuan. _which I paid 5 yuan. 1.This is the book _which I learnt a lot. _which Tom often

32、ked. 这就是他的父亲曾经工作过的那个工厂。 (定语从句) Put back the book where it was. 把书放回原处。 (状语从句) (3)限制性定语从句中的关系词在从句中充当某种句子成分,因此去掉它则从句成分不完整; 而结果状语从句中的连接词在从句中不作任何成分,去掉后从句的成分仍然完整。 It is such an interesting book as we all like. 它是我们大家都喜欢的如此有趣的书。 (as 用作动词 like 的宾语,它引导的是定语从句) It is such an interesting book that we all like

33、it. 它是一本如此有趣的书,我们大家都喜欢它。 that 不充当句子成分,故它引导的是结果状语从句) 3.定语从句与同位语从句定语从句与同位语从句 定语从句在复合句中相当于形容词,对先行词起修饰、描述或限制的作用,与先行词之间有 从属关系。同位语的作用相当于名词,对前面的名词给予补充说明或进一步解释,是前面名 词的具体内容,与先行词之间是同位关系。 The news that she had passed the exam made her parents very happy. 她考试及格的消息使她父母亲很高兴。 (同位语从句) The news that he told us inter
