在复合句中起名词作用的从句叫名词性从句 (Nun Clauses）。名词从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语等，因此根据它在句中不同的语法功能，名词从句又可分为:主语从句、宾语从句、表语从句和同位语从句。

1. 同位语the Appsitive 同位语是句子成分的一种, 它位于名词、代词后面, 说明它们的性质和情况, 它可以由名词、代词、名词性短语或从句充当。
同位语的表现形式有以下几种：(1) 名词 Tm, ur mnitr, is a handsme by. (2) 代词 I myself will d the experiment.(3) 数词 She is the ldest amng them six.
(4) 从句 He tld me the news that the plane had explded. 他告诉我飞机爆炸的消息。(5) 由such as, that is引导 Sme subjects, such as maths and physics, are very difficult t learn. 某些学科,例如数学和物理,是很难学的。
(6) 由f引导 The city f Beijing has been greatly changed since 2000. 自从2000年以来, 北京市发生了很大的变化。
(7) 由r引导 The freezing temperature, r freezing pint, is the temperature at which water freezes under rdinary pressure. 结冰温度即冰点,是水在常压下结冰时的温度。
2. 同位语从句the Appsitive clause(1) 同位语从句的定义 在复合句中用作同位语的从句称为同位语从句。同位语从句是名词性从句的一种。它在句中起同位语的作用。　
　它一般放在fact, news, idea, truth , hpe , prblem, infrmatin, belief, thught, dubt, prmise, questin 等名词的后面, 对前面的名词作进一步的解释, 说明前面名词的具体含义。引导同位语从句的词有连词that, 连接副词hw, when, where, whether, what等。
e.g. The hpe that he may recver is nt gne yet. The prblem whether we shuld cntinue t d the experiment has been slved. I have n idea when he will cme back.
同位语从句有时被别的词把它和名词隔开：
The stry ges that William Tell killed the king with an arrw. Wrd came that their team had wn.
⑵ 同位语从句的表现形式:① 由that引导 The fact that yu haven’t enugh time t d the wrk is simply unbelievable. The hpe that he may cme here is nt gne yet.
② 由whether引导 The questin whether we need mre time t d the wrk has nt been discussed.③ 由when引导 I have n idea when they will g.
⑶ 有时可用 namely (即), that is t say (也就是说), in ther wrds (换句话说), that is (那就是), fr example 等引出同位语, 说明其前面的名词或代词。有时同位语直接跟在名词或代词的后面。
He tld us the gd news, namely, the museum is pen t all. There is nly ne way f imprving yur English , that is , t practice mre.
⑷ 同位语从句与定语从句的区别: 同位语从句与定语从句在使用中常常混淆,我们可以从以下几个方面区别它们:① 同位语从句说明的名词大都是抽象名词; 定语从句所修饰、限定的名词或代词有抽象的也有不抽象的。
We express the hpe that they will cme t visit China again.(同位语从句)Thse wh want t g please sign their names here.(定语从句)
② 同位语从句所说明的名词与从句没有逻辑关系； 定语从句所限定的名词是从句逻辑上的主语、宾语、表语、定语、状语等。
The news that they wn the match is true.(同位语从句, news和从句没有逻辑关系)The news that yu tld us yesterday is true.(定语从句, news是tld的逻辑宾语)
③ 同位语从句主要由连接词that引导,有时也可用when, where, wh, whether等引导; 定语从句由关系代词或关系副词引导。 Then he raised the questin where they were t get the machine needed. D yu knw the place where he was brn?
④ 引导同位语从句的连词不可省略; 引导定语从句的关系代词作宾语时常可省略。 The news that he has been elected mnitr f ur class is true. The news (that) he tld me is exciting.
1._____________________(她赢了这场比赛) made us very happy. 2. ________________(所需要的) is careful preparatin. 3.__________________________(她是否来)desn’t matter t much. 4.That he will succeed is certain.(用it句型改写) ______________________________________ 5.Why he did this is nt knwn.
