1、精品资料 欢迎下载 定语从句和同位语从句的区别 一、定语从句是形容词从句，其作用相当于一个形容词，是用来修饰前面的名词或代词的；同位语从句是名词从句，其作用相当于一个名词，是对前面的名词作进一步解释的。例如：1 We heard the news that he had told her.我们听到他对她说的消息。2 We heard the news that he had won the game.我们听到消息他赢得了比赛。例 1 中的 that 从句的作用相当于一个形容词，其作用是修饰 the news；例 2 中的 that从句的作用相当于一个名词，是对 the news的进一步说明。二

2、、定语从句的引导词在从句中充当一定的成分，可作主语、宾语、状语等；而同位语从句中的引导词在从句只起连接作用，不作任何句子成分。例如：1.A plane is a machine that can fly.飞机是一种能飞的机器。2.The fact that they didnt finish the work has to be faced.必须面对事实，他们没有完成工作。例 1 中的引导词 that 在从句中充当句子成分，作从句的主语，故为定语从句；例 2 中的 that 只起连接作用，引导从句解释 fact的内容，不作任何句子成分，故为同位语从句。三、引导定语从句的关联词在从句中作宾语或状

3、语时，可以省略或被其他词代替；而同位语从句的引导词一般不能省略，更不能被代替。例如：1.The news that she heard is true.她听到的消息是真的。2.The news that she will go abroad is true.她将出国这消息是真的。例 1 是定语从句，that 可省略；例 2 是同位语从句，that 不能省略。3.The reason why he was chosen remains unknown.他为什么被选上的原因还是不清楚。4.The idea why he was chosen attracted our attention.他为什么

4、会被选上，这一想法引起我们的注意。例 3 中 why 引导的是定语从句，why 可以被 for which 或 that 代替；例 4 中 why 引导的是同位语从句，why 不能省去，也不能被其它词代替。四、同位语从句与其所修饰的名词之间是一种同位关系，二者之间存在逻辑上的系表关系，可用“主+系+表”结构来表示。例如：The news that he won the first place is true.他赢得冠军的那个消息是真的。上句若用“主+系+表”结构来表示，则是：The news is that he won the first place.消息是他赢得了冠军。意思合理，系表结构成

5、立，故为同位语从句。五、定语从句所修饰、限定的先行词可以是各类名词，可以有复数形式；而同位语从句一般都与抽象名词同位，一般没有复数形式。例如：1.The possibilities that she was offered seemed very great.她得到的可能性似乎大些。2.Her mother was worried about the possibility that her daughter dislike to go to school.她的母亲很担心，她女儿有可能不喜欢上学。例 1 中的 possibilities是定语从句的先行词，可用复数形式；例 2 中的 possi

6、bility是抽象名词，后接的是同位语从句，一般不用复数形式。六、由 when,why,where引导的定语从句分别修饰或说明表示时间、原因或地点的词，但它们引导的同位语从句一般不和表示时间或地点的词同位。例如：精品资料 欢迎下载 1.I still remember the day when I first came to Beijing.我仍然记得初次来北 京的那天。2.I have no idea when she will be back.我不知道她何时回来。3.This is the house where I lived two years ago.这是我两年前住的房子。4.The

7、 question where we shall have a meeting hasnt decided.我们到什么地方去开会，这个问题没有决定。例 1、3 中的 when 和 where 引导的是定语从句，day 和 house 分别表示时间和地点；例2、4 中的 when 和 where 引导的是同位语从句。同位语从句练习题 1.The fact _ she works hard is well known to us all.A.that B.what C.why D.which 2.The fact _ he was successful proves his ability.A.t
