高中英语知识点归纳同位语从句的用法及常见例句同位语从句是指在一个句子中作为同位语的从句，与同位语的先行词之间存在一种解释、说明或补充的关系。

同位语从句在高中英语中是一个重要的语法知识点，掌握其用法和常见例句对于理解和运用英语非常有帮助。

一、同位语从句的引导词同位语从句通常由连词that引导，也可以由whether/if引导。

二、同位语从句的用法同位语从句常见的用法有以下几种：1. 解释、说明与补充：例如：- I have no doubt that he will succeed.（我毫不怀疑他会成功。

）- The fact that he is late again surprises me.（他又迟到了这个事实让我感到惊讶。

）2. 告知、告诉、提醒：例如：- He made it clear that he won't be able to come.（他明确表示他不能来。

）- Tom informed us that the party was canceled.（汤姆告诉我们聚会取消了。

）3. 想法、观点、看法：例如：- My belief is that hard work pays off.（我的信念是勤奋会有回报。

）4. 目的、原因：例如：- The purpose of the meeting is that everyone can express their opinions.（会议的目的是让每个人都能表达自己的观点。

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。

一、同位语从句的定义1．在主从复合句中，在句中作某一名词尤其是抽象名词的同位语，一般位于该名词之后，说明该名词的具体内容的从句叫同位语从句。

2．能跟同位语从句的名词一般是fact, news, idea, truth, hope, problem, information, wish, promise, answer, evidence, report, explanation, suggestion, conclusion等抽象名词。
