Part Ⅲ Grammar & WritingGrammar——名词性从句Ⅲ：同位语从句一、概念在主从复合句中，跟在名词后进一步解释、说明该名词的具体内容，作同位语的从句叫同位语从句。常见的后跟同位语从句的名词有： fact, hope, desire, thought, suggestion, idea, news, problem, possibility, truth, decision, rule, evidence, conclusion, opinion 等。二、基本用法1．同位语从句的连接词及其功能I'm not sure about the question whether he will come.对于他来不来这个问题，我不太确定。They were worried over the fact that you were sick.他们为你生病发愁。[关键点拨] 在同位语从句中 that, whether 不作成分，that 只起连接作用，无任何实际意义，不可省略。whether 表示“是否”，if 不能替换 whether。2．同位语从句的注意事项(1)分隔式同位语从句：有时同位语从句与其所说明的名词会被其他成分隔开，从而形成分隔式同位语从句，这样做主要是为了保持句子结构平衡，避免头重脚轻。Word came that some wolves were caught around that village.有消息传来说在那个村子周围捕获了几只狼。(2)名词 suggestion, order, demand, command, request, desire, proposal 等后的同位语从句要使用虚拟语气，即从句谓语用“should＋动词原形”，should 可以省略。1He made a suggestion that I (should) start right now.他提出建议我应该立刻动身。(3)在肯定句中，名词 doubt 后的同位语从句用 whether 引导；在否定句或疑问句中，doubt 后的同位语从句用 that 引导。There is some doubt whether he will leave.对于他是否离开有些疑问。I have no doubt that he will be admitted into a key university.我坚信他会被一所重点大学录取。3．同位语从句与定语从句的区别The fact that the Chinese people invented the compass is known to all.中国人发明指南针这个事实是众所周知的。(同位语从句，fact 和从句没有逻辑关系也不作成分)The fact that we talked about is very important.我们谈论的这个事实很重要。(定语从句，fact 是 talked about 的逻辑宾语)2Ⅰ.用适当的连接词填空1 ． They asked her the question ____________ she was so late for the meeting.2．There was a suggestion ______...
