单元教研热点 同位语从句和定语从句的易混点 同位语从句和定语从句很相似，但还是有区别的，区别主要在以下三个方面： 1．从词类上区别： 同位语从句前面的名词只能是idea，fact，news，hope，belief，suggestion. proposal，word，thought，doubt，truth.possibility，promise，order 等有一定内涵的名词，而定语从句的先行词可以是名词、代词、主句的一部分或是整个主句。如： ①The possibility that the majority of the labor force will work at home is often discussed. 人们经常讨论大多数劳动力将会在家里工作的可能性。(同位语从句) ②We are not looking into the question whether he is worth trusting. 我们正在调查的不是他是否值得信赖的问题。(同位语从句) ③Word came that he had been abroad. 据说他已经出国了。(同位语从句) ④Our team has won the game，which made us very happy. 我们的队赢了，这让我们很高兴。(定语从句) ⑤The doctor whom you are looking for is in the room. 你正在找的那位医生在房间里面。(定语从句) ⑥His mother did all she could to help him with his study. 他妈妈尽她的最大努力帮助他的学习。 (定语从句，代词 all作先行词) 2．从性质上区别 定语从句是从句对其先行词的修饰或限制，属于形容词性从句的范畴；而同位语从句是从句对前面抽象名词的进一步说明和解释，属于名词性从句的范畴。例如： ①The news that our team has won the game was true. 我们队赢了那场比赛的消息是真的。(同位语从句，补充说明 news到底是一个什么消息) ②The news that he told me yesterday was true. 昨天他告诉我的那个消息是真的。(定语从句，news在从句中作 told 的宾语) ③I made a promise that if anyone set me free I would make him very rich. 我许诺如果谁让我自由，我就让他非常富有。(同位语从句，补充说明promise到底是一个什么诺言) ④The mother made a promise that pleased all her children. 妈妈做出了一个令她的孩子们高兴的承诺。(定语从句， promise在从句中作pleased的主语) 3．从引导词及其在句子中的成分上区别 (1)有些引导词如 how，whether，what 可以引导同位语从句，但不能引导定语从句。例如： ①That question whether we need it has not been considered. 我们是否需要它这个问题还没有考虑。(同位语从句) ②I have no idea what has happened to him. 我不知道他发生了什么事。(同位语从句) (2)引导词that引导定语从句时，在从句中一般作主语或宾语(指物时还可以用which代替)并且作宾语时常常省略；that在同位语从句中仅起连接作用，不充当任何成分，并且不能省略，也不能用which来代替。如： ①The order that we should send a few people to help the other groups was received yesterday. 我们应派几个人去帮别的几个小组的命令昨天收到了。(同位语从句是对order的具体解释，that虽不作成分，但不能省略) ②The order that we received yesterday was that we should send a few people to help the other groups. 我们昨天收到的命令是我们应该派几个人去帮助别的几个小组(定语从句，修饰名词order，that在从句中作received的宾语，可以省略) 最后我们再一起来做三道练习题： ①Along with the letter was his promise that he would visit me this coming Christmas. ②The other day，my brother drove his car down the street at what I thought was a dangerous speed. ③Luckily，we'd brought a road map without which we would have lost our way. 学科网（北京）股份有限公司 $
