同位语从句讲解

1、初中英语语法同位语从句专项讲解与训练（一）概念一般来说，在主从复合句中 用作同位语的从句叫同位语从句。它通常跟在某些名词之后，用以说明或解释该名词表示的具体内容。可以跟同位语从句的名词通常有：advice, decision, fact, hope, idea, information, message, news, promise, proposal, reply, report, suggestion, word （消息），problem, question, doubt, thought等。 例如：They were delighted at the newsthat their tea

2、m had won.当听到他们队获胜的消息时，他们欣喜若狂。Where did you get the ideathat I could not come?你从哪儿听说我不能来？有时同位语从句可以不紧跟在被说明的名词后面，而被别的词隔开。如：The thought came to himthat Tom might have returned the book.他突然想起汤姆可能已经还了书了。（二）引导词请仔细观察下列句子，注意从句引导词的用法。1. The newsthat Mr. Li will be our new English teacher is true.2. He hasn&#

4、can get to the railway station.7. I have no ideawhen he will be back.小结归纳that引导同位语从句时无词义，也不充当任何成分，但通常不可以 省略，如句1;whether引导同位语从句时意为 是否工通常不能用if来代替，如句2；连接代词who, what等可以引导同位语从句，如句 3, 4;连接副词where, how, when等可以引导同位语从句，如句5,6,7。（三）that引导的同位语从句和定语从句意义不同：同位语从句用来进一步说明前面名词的内容；而定语 从句用来修饰、限定前面的先行词。试比较：1. The news

5、that our team has won the final match is encouraging.2. The news that you told us is really encouraging.分析句1中that引导同位语从句，说明“new朝内容：我们队取得 了决赛胜利。句2中that引导定语从句，对“new动口以限定：是你告 诉我们的，而非来自其他渠道。that的功能不同：that引导同位语从句时是一个纯连词，不充当任 何成分；而引导定语从句时，不仅起连接作用，而且还指代先行词并 在从句中充当主语、宾语等成分。试比较：1. Dad made a promise that he

6、would buy me a CD player if I passed the English test.2. Dad made a promise that excited all his children.分析句1中that弓I导同位语从句，其中that无词义，也不充当任何成分；句2中that引导定语从句，that指代promise,又在从句中 充当主语，且that可以用which替换。可否省略：that在引导同位语从句时，通常不可省略。在引导定语 从句时，若在从句中作宾语，通常可以省略，若作主语则不可以省略。即学即用I.请用适当的词填空，使下列句子意思完整。1.
