名词性从句中用哪个连接词，主要是根据在句中所作的句子成分和意义决定的。
宾
主
表
同位
语法探究·核心突破
1.名词性从句概述
主语从句、宾语从句、表语从句和同位语从句在复合句中的作用，相当于名词，因此这四种从句统称为名词性从句。它们有下列相同之处：
(1)关联词大抵相同。
①连词：that, whether, if
②疑问代词：who, what, which, whom
③疑问副词：when, where, why, how...
(2)需用陈述语序。
(3)四种从句一般不用逗号和主句分开。
2．主语从句
(1)主语从句在复合句中作主句的主语，它的位置与陈述句基本结构中的主语相同。引导主语从句的关联词有从属连词that, whether，疑问代词who, what, which, whom，疑问副词when, where, why, how等。
That colours influence our moods has been proved.颜色能影响我们的情绪已经得到了证明。
Whether our team will win the match remains to be seen.我们队能否赢得比赛的胜利还得等等看。
What they are looking for is their missing dog.
他们正在寻找的东西是他们失踪的狗。
Who will take the place of Mr Yang is still unknown.谁将代替杨先生尚不清楚。
When they are leaving for Hong Kong by plane has been decided.
他们什么时候乘飞机去香港已经定下来了。
(2)为了保持句子平衡，可用it作形式主语，真正的主语从句放后面。
常见的it作形式主语的结构：
①it＋be＋形容词＋that从句。常用于这种结构的形容词有：
important 重要的
right 正确的
strange 奇怪的
certain 明确的
obvious 明显的
necessary 必要的
wrong 错误的
(un)likely (不)可能的
clear 清楚的
natural 自然的
It's not immediately clear whether the financial crisis will soon be over.
危机是否能马上过去还不能立刻清楚。
②it＋be＋名词＋that从句。常用于这种结构的名词有：
a pity 遗憾
a fact 事实
a wonder 奇迹
a shame 遗憾；耻辱
an honour 荣誉
It is a great pity that you can't go abroad for further education.你不能去国外深造真是一个遗憾。
③it＋be＋过去分词＋that从句。常用于这种结构的动词有：
said 据说
reported 据报道
decided 决定
ordered 命令
announced/declared 宣布
believed 据认为
hoped 希望
suggested/advised 建议
thought 认为
It is said that the boy has a great gift for language.据说这个男孩在语言方面很有天赋。
3．宾语从句
(1)在句子中起宾语作用的从句称为宾语从句。宾语从句的从属连词有that, whether, if，连接代词主要有who, whom, whose, what, which, whoever, whomever, whatever, whichever等；连接副词主要有when, where, why, how, whenever, wherever, however等。
Many people believe that teaching children music makes them smarter, better able to learn new things.许多人都认为教孩子音乐可以使他们更聪明，更能学新东西。
动词短语后的宾语从句
有些动词短语如find out, point out, work out, turn out, make sure, make up one's mind, keep in mind等后可以带宾语从句。
Have you found out when the next train to Beijing will leave
你已经弄明白下一趟去北京的火车什么时候离开吗？
(2)为了平衡句子，可用it作形式宾语，真正的宾语从句放后面。常用的句型：
①...make it possible/easy/difficult... that...
使……可能/容易/难……
②...find/feel it necessary... that... 感觉/认为……必要
③...make it clear that...说清楚……
④...make it a rule that...使……成为习惯……
⑤...take it for granted that... 认为……是理所当然的……
⑥...bring it to one's attention that... 使……注意……
⑦...see to it that...务必/一定……
The Internet makes it possible that we can work from home.因特网使我们在家里工作成为可能。
(3)不可省略that的宾语从句
①宾语从句被其他成分分隔时。
We don't doubt, in any case, that he keeps his promise.
我们相信在任何情况下他都遵守自己的诺言。
②当有两个或两个以上的宾语从句时，第一个that可以省略，但后面的that不能省略。
Scientists find (that) the number of wild goats has increased and that a new species has appeared.
科学家们发现野羊的数目增加了，而且还出现了一个新种群。
4．表语从句
在句子中起表语作用的从句称为表语从句。
(1)表语从句的连接词有从属连词that, whether；连接代词who, whom, which, what, whoever, whomever, whatever, whichever；连接副词when, where, why, how...等。
The trouble is that I have no one to ask for help.
问题是我无人可求。
(2)系动词be＋表语从句。
表语从句多用在系动词be的后面。
The problem is that so many people don't have enough water to drink in Africa.
问题是在非洲有那么多的人没有足够的水喝。
(3)连系动词＋表语从句
连系动词seem, look, appear, sound, taste, feel, remain等后也接表语从句。
The black clouds are gathering. It looks as if it is going to rain.乌云密布，天看起来要下雨了。
5．同位语从句
在句子中起同位语作用的从句称为同位语从句。它一般在某些名词的后面，用以说明或解释前面的名词。
(1)that引导的同位语从句
从属连词that引导同位语从句，其先行词多为：
belief 信念，相信
explanation 解释
wish 愿望
dream 梦想
message/information 信息
possibility 可能性
thought 想法
question/problem 问题
suggestion/advice 建议
fear 恐惧
doubt 怀疑
hope 希望
truth 事实
promise 承诺
reason 原因
order 命令
warning 警告
There is no doubt that human activity caused global warming.
毫无疑问人类活动导致了全球变暖。
(2)也可用whether, what, how, when, why等引导同位语从句。
They're talking about the problem whether we can land on the moon.
他们正在讨论我们能否登上月球这个问题。
The problem why he gave up his well paid job made me annoyed.
他为何放弃自己的高薪工作这个问题让我很烦。
①以that引导的名词性从句
从属连词that在主语从句中不作任何成分，只起连接作用，无意思，不能省略。
②以whether引导的主语从句
从属连词whether在主语从句中不作成分，只起连接作用，意为“是否”。
③连接代词what, who, which, whom在从句中常作主语、宾语、表语，起连接作用，有意义。
④连接副词when, where, why, how等引导的名词性从句，连接副词在从句中常作状语，起连接作用，有意义。
