同位语从句【教学内容】同位语从句【教学目标】熟练掌握同位语从句【教学重难点】引导词的使用、同位语从句与定语从句的区别【教学过程】* 什么是同位语从句：同位语从句是名词性从句中的一种，是用以解释说明某一名词内容和实质的从句，它所修饰的词称为先行词。
同位语从句在主句中的作用等同于先行词的作用。
Eg:The news that we’ll go on a picnic this Sunday isn’t true.这个星期天我们要去野餐的消息不是真的。
析：The fact就等于we’ll go on a picnic,是对the fact 的解释说明。
▼同位语从句常修饰的名词不是所有的名词都可以跟同位语从句，可以被同位语从句修饰的多是含有抽象意义的名词。
常用的有：●advice 建议●belief 信念、相信●doubt 怀疑●explanation 解释●fear 害怕●fact事实●hope 希望● idea 想法、主意●news 消息●order 命令●opinion 观点●possibility 可能性●promise 答应、诺言●problem 问题●question问题●report 报道●reply答复●statement论断●suggestion建议●thought想法●truth事实●wish 愿望●warning 警告●word 消息* 同位语从句的连接词的使用►由that引导Eg:①We heard the news that our team had won.我们听到我们队赢了。
②They were worried over the fact that you were sick.他们为你生病发愁。
③The news that we are having a holiday tomorrow is not true.明天放假的消息不实。
►在某些名词，例如suggestion,advice,request,order,demand,requirement等意为“建议，命令，要求”的名词后，同位语从句的谓语动词通常用“should+动词原形”的虚拟语气结构，句中should可以省略。

1. Dad made a promise that he would buy me a CD player if I passed the English test.2. Dad made a promise that excited all his children.③that引导同位语从句时是一个纯连词，故不能用which替换；而that引导定语从句时是代词，常可以和另一关系代词which替换。
