高中英语Unit5 从同位语到同位语从句素材新人教版必修3
从同位语到同位语从句一、同位语同位语是英语中的一种句子成分，用来补充说明另一个名词(短语)或代词的具体内容或情况；同位语常由名词、代词、数词、形容词或词组来充当。
1. 名词(短语)后常跟另一名词作它的同位语。
如：This is Professor Baker, head of our department.分析：名词短语head of our department作Professor Baker的同位语，解释说明其具体情况。
2. 有些同位语是代词或数词。
如：We each put forward a proposal.分析：本句中的each是代词，作we的同位语，以补充说明参与执行动作put forward a proposal的主语we的范围。
3. 有时可用形容词作同位语。
如：Middle-aged, tall and thin, he looked like a typical farmer.分析：形容词短语middle-aged和tall and thin作代词he 的同位语，用来补充说明其年龄和体貌特征。
4. 较复杂的词组作同位语。
如：They visit eight cities, for example, London and Paris.分析：这句话中的同位语由for example引出，同时它们也都是同位语不可或缺的一部分。
二、同位语从句如果用整个句子充当同位语，那么这个句子就叫同位语从句。
它是名词性从句(主语从句、表语从句、宾语从句、同位语从句)中的主要从句之一，在使用同位语从句时，应注意以下几个方面：★同位语从句实质同位语从句在主从复合句中作某一名词的同位语，也就是说同位语从句说明被修饰名词的具体内容。
如：The fact that he will come is surprising.★同位语从句在句中的位置1. 一般情况下同位语从句直接跟在某些名词如news，idea，fact，promise，hope，message 等的后面，用以说明该名词所表达的具体内容。

高中英语学习材料madeofjingetiejiUnit 5 Canada―“The True North语法探究：同位语从句课前自学（ SB P37 Discovering useful structures）语法知识精讲1.同位语从句是名词性从句的一种，常用从属连词that引导，（when, where, who等也可引导），常常跟在fact, idea, opinion, news, hope, ability, patience, answer, order, report, wish, decision, suggestion, belief, doubt, fact, hope, message, promise, question, reply等名词后。
同位语从句一般用来解释或说明这些名词的具体含义或内容。
在逻辑上表现为同位关系。
例如：①Finally the workers got an answer that the government could do nothing to raise their wages.工人们最终得知政府不会采取任何措施来增加他们的工资。
②They are familiar with the opinion that all matter consists of atoms.他们很熟悉这一观点，所有的物质都是由原子构成的。
2.同位语从句与that引导的定语从句的区别：1）从先行词来看同位语从句与名词在本质上是同一的，是形式与内容的关系，该名词是需要做特殊说明的抽象名词。
例如：They were delighted at the news that their team had won.当听到他们的球队赢了的消息时，他们欣喜若狂。
逻辑关系：The news was that their team had won.2) 从引导词来看引导词that在同位语从句中是连词，只起连接作用，无具体含义，that不可省略；that 在定语从句中是关系代词，他在从句中充当一定成分：主语或宾语，有具体词意，作宾语时还可以省略。
