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等表抽象意义的名词，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。同位语从句与定语从句区别1.从词类上区别44Hetoldmethenews

thathewouldcomehomefromaboardsoon.Wordcamethathehadbeenabroad.据说他已经出国了。Ourteamhaswonthegame,whichmadeusveryhappy.我们的队赢了,这让我们很高兴。(同位语从句)(定语从句)

Hetoldmethenewsthathewo452.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的说明和解释，属于名词性从句的范畴。如:2.从性质上区别46Thenews

that

ourteamhaswonthegameistrue.

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)Thenews

that

hetoldmeyesterdaywastrue.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)Thenewsthatourteamhaswon473.从引导词及其在句子中的成分上区别有些引导词如how,whether,what可以引导同位语从句,但不能引导定语从句。如:Thatquestionwhetherweneedithasnotbeenconsidered.我们是否需要它这个问题还没有考虑。(同位语从句)3.从引导词及其在句子中的成分上区别48

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:引导词that引导定语从句时，在从句中一般作主语或宾语49Theorderthatweshouldsendafewpeopletohelptheothergroupswasreceivedyesterday.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)Theorderthatweshouldsend50Theorderthatwereceivedyesterdaywasthatweshouldsendafewpeopletohelptheothergroups.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,是名词order的修饰语,that
