文档介绍

文档介绍:同位语从句 1. 概念:在复合句中作名词的同位语的名词性从句。 2. 功能:同位语从句对名词进一步解释,说明名词的具体内容。 3. 用法: 常跟的抽象名词有: fact/ idea/reason/ thought/order/ doubt/news/hope/ truth/belief … 4. 连词 that/whether/who/ which/ what /when /where/why/how 引导同位语从句引导同位语从句的 that 在从句中不充当任何成分,无任何具体意思,一般不省略。同位语从句常用 that 引导,与其同位的名词常有: news, fact, hope, idea, suggestion, promise, thought, doubt, belief 信任/信仰, truth, request, proposal 提议/建议, demand 等抽象名词。 eg. The news that our team won the first prize excited all of us. 我们队得了第一名,这消息使我们都很兴奋。同位语从句还可用 whether, how , when, where, why 等引导。 eg : I have no idea how he did it. 注意:除 that 外, 其余连词在从句中都具有各自的意义和成分。 eg : He must answer the question whether he agrees to it or not. 状语 You have no idea how worried I was. 状语 heard the news last night that the Queen of England was on a three-day visit in China. British parents hold the view that teenagers shouldn ’ t spend too much time online. is no scientific proof for the idea that time travel is possible. suggestion that Chinese students should be given more free time is ed by many people, especially kids in school. demand , suggestion, proposal 等同位语从句的谓语动词要用虚拟语气,即: ( should ) + 动词原形 eg. The suggestion that the plan ( should ) be delayed will be discussed tomorrow. 推迟那项计划的建议将在明天讨论。虚拟语气在同位语从句中的用法同位语从句与定语从句的区别: 比较 We expressed the hope (that) they had expressed. We expressed the hope that they e to visit China again. 定语从句同位语从句(1)从语法角度上看,引导同位语从句的 that 是连词,只起连接的作用,在从句中并不作任何句子成分;而引导定语从句 that 的是关系代词,除了起连接作用外,还在从句中作句子成分. ( 2 ) 从语义角度上看,同位语从句与前面的名词(如 hope) 是同位关系,表示这个“希望”的内容是“他们再来中国访问”;而定语从句与前面的名词是所属关系,表示“…的‘(如第一句中的”他们曾经表示过的“),起修饰作用。( 3 )同位语从句的连词 that 一般不能省略;而定语从句中的关系代词 that ,当其在从句中作宾语中,常常可以省略(如第一句中的 that 可以省略) 同位语从句的简易判断方法: 我们可以在名词和从句之间加 be, 使之构成一个新句子,如果合乎逻辑,句子通顺,则是同位语从句,定语从句是不能用系表结构把先行词与从句连接起来的。 eg : The belief that the earth is flat is still held in some countries. The belief is that the earth is flat. 判断下列哪些含有同位语从句,哪些含有定语从句。① The news that we had
