3、 book.The book interests me.先行词先行词关系词（充当主语）关系词（充当主语）限制性定语从句限制性定语从句 restrictive relative clause非限制性定语从句非限制性定语从句 non-restrictive relative clause定语从句定语从句类型关系图类型关系图 限制性定语从句起限制性定语从句起限定限定作用：作用：修饰修饰特定的特定的名词名词或或名词短语名词短语 非限制性定语从句只起非限制性定语从句只起补充说补充说明明某种信息的作用某种信息的作用限制性定语从句限制性定语从句从语义上看，限制性定语从句主要起限定作用，修饰特定的特定的人或事

4、物人或事物，如果去掉去掉限制性定语从句，整个句子表意会不完不完整整甚至不通顺不通顺;从结构上看，限制性定语从句常紧跟先行词常紧跟先行词，并且同先行词之间一般不加逗号分隔一般不加逗号分隔(但不是绝对的)。限制性定语从句的关系词包括:that,which,who,whom,whose,as,than等。非限制性定语从句非限制性定语从句从语义上看，非限制性定语从句主要起补充说明补充说明的作用，有时相当于一个并列分句或状语从句，可以表达原因、目的、原因、目的、结果、条件、让步结果、条件、让步等意义。例如:Dr Lee,who had read through the instructions care

5、fully before doing his experiments,did not obtain satisfactory results.(非限制性定语从句表示让步的意义，相当于though Dr Lee had read through the instructions.)非限制性定语从句的关系词包括:which,who,whom,whose,as等，另外that在非限制性定语从句中基本不可基本不可使用。举个栗子举个栗子eg.The government which promises to cut taxes will be popular.The government,which pr

6、omises to cut taxes,will be popular.There were very few passengers who escaped without serious injury.There were very few passengers,who escaped without serious injury.(限制性定语从句限制性定语从句)(非限制性定语从句非限制性定语从句)(限制性定语从句限制性定语从句)(非限制性定语从句非限制性定语从句)关系词包括关系代词(relative pronoun)、关系副词(relative adverb)。关系词的选择主要涉及以下因素

7、:先行词是人人还是事物事物;关系词在关系从句中的句法功能句法功能;关系从句是限制性限制性的还是非限制性非限制性的;是口语还是书面语。例如例如:He always remembered the day when(=on which)his father returned from America.有些词如case,condition,point等也可以看做是表示(抽象的)地点的词，因此其关系从句的关系词也可以选择where。关系副词引导的定从和状从区别关系副词引导的定从和状从区别 本质不同本质不同区分点：区分点：从句之前是不是n.，且此n.被从句修饰状从状从是可以放在整个句子最前面的，前面可以没

8、东西没东西，也可以整个主句写完再写从句（很多时候主从的先后是可以颠倒主从的先后是可以颠倒的）The time【when we played everything together】was a wonderful memory.从句把主句岔开了，从句跟在time后头就是修饰time，故为定从。定从的位置是唯一唯一的：如果把它挪到句末，就变成了修饰memory了，句意会有误。【When we played everything together】,we were still young children.可以从句写在最前面的就是状从，状从可以和主句先后整体对换一下，但是注意，如果此时你把它看成从句

9、的话，就确认下从句是否在修饰它前面的名词children，不是不是修饰children，故它不是不是定从。语法想要学通透，必须建立于语法想要学通透，必须建立于“语感基本无误、每个句子都能顺利分割意群区块语感基本无误、每个句子都能顺利分割意群区块”Complete the box of part A on page 34，and find the sentences with restrictive relative clauses.AnswerA real friend is someone who walks in.A real friend is someone whose support
