It looks as if it is going to rain. This is because he missed the train by one minute.

He said (that) the text was very important and that we should learn it by heart.
3)用whether或if引导的宾语从句
We don’t believe that he will win the game.
I don’t think he will do so.
doubt用于肯定结构时，后面用
whether/ if 引导名词性从句；
用于否定结构或疑问结构时，后面
用 that 引导名词性从句。
be sure 用于肯定句或疑问句时，后 接 that 引导的名词性从句；
It is known to us how he became a writer.
我们都知道他是如何成为一名 作家的。
2. 宾语从句 名词从句用作宾语叫宾语从句。
引导宾语从句的关联词与引导主 语从句表语从句的关联词大致一 样，在句中可以作动词或介词的 宾语。
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，但有两个以上宾语从句时, 第二个分句前的that不可省。
A.what man will look like B. what will man look like C. man will look like what D. what look will man like
3.考查it在名词性从句中作形式 主语或形式宾语的用法 高考题例示：
1. _____ is a fact that English is being accepted as an international language. (NMET1995)
I have no idea when she will be back.
I had no idea that you were here.
(that引导同位语从句,不能省略）
Have you got the idea（that）this book gives you of life in ancient Greece？ (that引导定语从句，作宾语， 可以省略）
同位语从句一般跟在某些表示 抽象概念 的名词后,如 news, idea, information, fact, hope, thought, belief 等，用来说明名 词所表示的具体内容，
引导同位语从句的连接词通常 有that, whether和连接副词when, where, why, how；连接代词 who，what，whose，which通 常不引导同位语从句。
3. 表语从句 在句中作表语的句子叫表语从句。
引导表语从句的关联词与引导 主语从句的关联词大致一样， 表语从句位于连系动词后，有 时用as if, because 引导。其基本 结构为：
主语 + 系动词 + 连接词
The fact is that we have lost the game.
That’s just what I want.
A. There B. This C. That D. It
用于否定句时，后接whether/if 引 导的名词性从句。
连接代词whoever，whatever， whichever可引导名词性从句， 相当于anyone who, anything that 等。它们也可以引导让步状语 从句，相当于 no matter who/ what/ which。
Whoever breaks the law should be punished.
whether和if均可引导动词后的 宾语从句，常可互换。但从句 中有or not时或介词后的宾语从 句中只能用whether连接。其它 名词性从句，如：主语从句、 表语从句、同位语从句只用 whether.
I don’t care about whether you have money or not.
Everything depen4)当主句是I/ We think (suppose, expect, believe, guess, imagine) 时， 其后的宾语从句如果是否定形式， 常把否定词not从从句中转移到主 句中成为否定的转移。
有时为避免句子头重脚轻，常 用it 代替主语从句作形式主语 放于句首，而把主语从句置于 句末。主句的谓语动词一般用 单数形式。常用句型如下：
1）It + be + 名词 + that从句 2）It + be + 形容词 + that从句
3）It + be + 动词的过去分词 + that从句
4）It + 不及物动词 + that 从句
在名词性从句中一律用陈述句 的语序，即使从句表达的是疑 问含义。
The problem is what he has done to the little boy.
问题是他对那个小男孩做了些 什么。
1. 主语从句 在句中作主语的句子叫主语从句。
主语从句通常由从属连词that， whether 和连接代词what, who, which, whatever, whoever以及连 接副词how,when,where, why等 词引导。
2.考查引导词that与what的区别 高考题例示： 1. ______we can’t get seems better than ______we have. (NMET1996)
A. What; what B. What; that C. That; that D. That; what
2. No one can be sure _____ in a million years. (MET1991)
1. The photographs will show you ____．（MET1989）
A.what does our village look like B.what our village looks like
C.how does our village look like D.how our village looks like
Where the English evening will be held has not yet been announced.
That he stole a bike was true.
单个的主语从句作主语时，谓 语动词用单数形式。
Where and when he was born has not been found.
在复合句中起名词作用的从 句叫做名词性从句。
主语从句 表语从句 名词性从句 宾语从句
同位语从句
引导名词性从句的关联词
连接代词 who, whom, whose, which, what, whatever
连接副词 how, why, when, where however, wherever
连接词 that, whether, if, because as if /as though（不充当 从句的任何成分）
that在从句中无词义，只起连接 作用；连接代词和连接副词在 句中既保留自己的疑问含义、 又起连接作用，在从句中充当 成分。
What he wants to tell us is not clear.
他要跟我们说什么，还不清楚。
Who will win the match is still unknown.
需要注意的是，当主语是reason 时，表语从句要用that引导而不 是because。
The reason why he was late was that he missed the train by one minute this morning.
4. 同位语从句 同位语从句说明其前面的名词 的具体内容。
