第八讲 名词性从句 2015.11.20 名词性从句是高中阶段英语学习的重点，也是高考的主要考点之一。做题时一定要学会分析句子结构，理解题干的具体语境，才能有针对性的应考。 名词性从句在高考中的考查重点主要集中在对连接词的正确把握。近几年连接词what的用法成为考查的热点。另外，that和what引导名词性从句的区别；名词性从句的语序和时态；it作形式主语、形式宾语的几种情况以及其它连词的用法也时有考查。 一、名词性从句的连接词 连接词及从句类型 典句示例 备注 连接词that，whether，if。that在句中只起连接作用，无词义，不作成分，有时可省略；whether和if不充当成分，意为“是否”，不能省略 主语从句 (1)句首不能省略that (2)位于句首的主语从句一般用whether 宾语从句 I believe(that)they will finish the work in time. I went in and asked if/whether there was a John living there. (1)that可以省略 (2)if与whether可互换 (3)作介词宾语时一般用whether 表语从句 The fact is that I have never been there. The question is whether it is worth doing. The problem is where we should stay. (1)that一般不省略 (2)用whether而不用if 同位语从句 The fact that Luo Jing died made a lot of audience sad.

(1)that不能省略 (2)用whether而不用if That he will come is certain.(that不可省略) Whether she’s coming or not doesn’t matter.(不能用if) 连接词及从句类型 典句示例 备注 连接代词who，whom，whose， which，what， whatever，whichever，和where，when，why，how等连接副词它们都有各自的意义，连接代词在从句中作主语、表语、宾语或定语。连接副词在从句中作状语 主语从句 What he said is very important to us. Which side will win is not clear. Why he came late today has been clear now. (1)用陈述语序 (2)what从句相当于“先行词＋that引导的定语从句”。what＝the thing(s)/place/person that 宾语从句 Pay attention to what the teacher said.
