名词性从句的作用相当于名词，因此主语从句、表语从句、宾语从句和同位语从句分别作主句的主语、表语、宾语和同位语。
本单元主要学习宾语从句和表语从句。
5种基本句型The weather is very cold.主语+谓语（连系动词）+表语He laughed.主语+谓语（vi.）I like Chinese food.主语+谓语(vt.)+宾语She taught them physics.主语+谓语(vt.)+间接宾语+直接宾语We must keep the room warm.主语+谓语(vt.) +宾语+宾语补足语表语从句是在复合句中作表语的名词性从句,放在系动词之后,一般结构是“主语+系动词+表语从句”。
可以接表语从句的系动词有be, look, remain, seemThis is his job.（表语）They are my friends.(表语）The fact is that we have lost the game. （that 引导的表语从句）引导名词性从句的关联词：从属连词that, whether,as if/as though(不作成分）连接代词what, who, whom, whose, which, wh+ever（作成分）连接副词when, where, how, why.because（作状语）1）The question is _ weather____we can rely on him.2）That’s _because____we were in need of money at that time .3）He looked __as if__he was going to cry .4）That’s _why____I was late .注意：在表语从句中，表“是否”时，只能用“whether”不能用“if”。
引导表语从句的that通常不省略，但在口语或非正式文体中有时也可省略：My idea is (that) we should do it right away. 我的意见是我们应该马上干。
引导名词性从句的连接词可分为三类：连接词：that, whether, if （不充当从句的任何成分）连接代词：what, whatever, who, whoever, whom, whose, which.连接副词：when, where, how, why一、宾语从句宾语从句在复合句中作主句的宾语。
句子结构：主句 +连词（引导词）+ 宾语从句1. 由连接词that引导的宾语从句由连接词that引导宾语从句时，that在句中不担任任何成分，在口语或非正式的文体中常被省去，但如从句是并列句时,第二个分句前的that不可省。
例如：I realize( that )I'm in charge and that everybody accepts my leadershi p.We must never think (that) we are good in everything while others are good in nothing.注意：在demand、order、suggest、decide、insist, desire, demand, request, command 等表示要求、命令、建议、决定等意义的动词后，宾语从句常用“（should）+ 动词原形”。
例如：I insist that she (should) do her work alone. 我坚持要她自己工作。
The commander ordered that troops (should) set off at once. 司令员命令部队马上出发。
2. 用who，whom, which, whose, what, when, where, why, how, whoever, whatever, whi chever,等关联词引导的宾语从句相当于特殊疑问句，应注意句子语序要用陈述语序。
I want to know what he has told you. 我想知道他告诉了你什么。
