4、语从句通常出现在先行词之后，由关系词（关系代词或关系副词）引出。定语从句概述定语从句的分类：分为两大类This is the book that you want.这就是你要的那本书。(若把that you want去掉，意思就不够清楚。)He is a man everyone respects.他是一个人人都敬重的人。(若把从句去掉，句子就失去意义。)【分析】上面两个句子中的从句很重要，说明所修饰词的意义不可或缺，是句子的主要组成部分。译成汉语时也多译成一个定语(如：你要的那本书、人人敬重的人)。像上面两句这样的定语从句叫限制性定语从句(restrictive attributive cl

5、auses)。限制性定语从句 对所修饰的名词或代词(即先行词)起到限定作用，表示“的人(事物)”，一般说来如把从句去掉句子意思就不清楚，甚至失去意义。像这样从句和主句关系十分密切，书写时不用逗号隔开的定语从句叫限制性定语从句。The man who told me this refused to tell me his name.告诉我这事的人不肯告诉我他的名字。非限制性定语从句(non-restrictive attributive clauses)：还有一种定语从句，与主句关系不太紧密，对所修饰名词或代词(即先行词)的意思没有太大影响，把它们拿掉，句子依然很完整，它们可以说是附加上去的东西

6、，而且通常都有逗号把它们和句子的其他部分分开，这种从句称为非限制性定语从句。My sister,who is a nurse,came home for a few days.我姐姐是护士，她回家待了几天。(这种句子译成汉语时常译成两个并列句。)1.引起限制性定语从句的关系代词有：that,which,who,whom,whose；指代内容所做成分是否可省略thatwhichwhowhomwhose人；物物人人(人/物)的主语,宾语主语,宾语主语,宾语宾语定语作宾语可省作宾语可省作宾语可省可省不可省The girl who spoke is my best friend.讲话的姑娘是我最好的朋

8、作定语，修饰mind。)注：whose 表示“的”，是所有格，必须带名词，其本身有限定词的功能：The man whose houses were damaged will be compensated.房子被损坏的人将得到赔偿。whose有时可指动物或无生命的东西：It was an island whose name I have forgotten.这是一座岛，名字我忘了。He that would eat the fruit must climb the tree.想吃果子的人就得爬树。(that引起定语从句，修饰he,在从句中that作主语，代表he。)注：that可以代表人(相当于

12、ng last summer.这就是我们去年夏天住的旅馆。where引导的定语从句也可以修饰case,condition,situation,instance等先行词。Can you think of a situation where this word can be used?why在定语从句中作原因状语，相当于for which。Do you know the reason why(=for which)she is late?你知道她迟到的原因吗？She didnt tell me the reason why she refused the offer.她没跟我讲她拒绝这项工作的原因
