二、主语从句与形式主语it
有时为了考虑句子平衡，通常在主语从句处使用形式主语it，而将真正的主语从句移至句末。这分三种情况：
(1) 对于以连词that引导的主语从句，通常用形式主语代主语从句：

Whether they would support us was a problem. 他们是否会支持我们还是一个问题。
It was a problem whether they would support us. 他们是否会支持我们还是一个问题。
It remains to be seen whether it will do us harm or good. 它对我们是利是害，还得看看再说。
(3) 对关系代词型what引导的主语从句，通常直接将主语从句放在句首。如：
What we need is money. 我们需要的是钱。
What I want to know is this. 我想知道的就是这一点。
有时也可将助用形式主语。如：

(4) 如果句子是疑问句，则必须用带形式主语it的结构：
Is it true that he is the girl’s father? 他是那女孩的父亲，是真的吗?
How is it that you are late again? 你怎么又迟到了?
三、连词that的省略问题
引导主语从句的连词that 有时可省，有时不能省，其原则是：若that引导的主语从句直接位于句首，则that不能省略;若that引导的主语从句位于句末，而在句首使用了形式主语it，则that可以省略：
That you didn’t go to the talk was a pity. 很遗憾你没去听报告。(that不可省)
It was a pity (that) you didn’t go to the talk. 很遗憾你没去听报告。(that可省)

有极个别介词(如but, except)可接that引导的宾语从句：

比较下面两句用what引导的宾语从句，它们的意思不一样：

二、宾语从句与形式宾语it

【注】有时为了强调，that引导的宾语从句可位于句首，此时that不可省略：

二、关于分离同位语从句
有时同位语从句可以和同位的名词分开。如：

三、同位语从句与定语从句的区别
1.意义的不同
同位语从句是用于说明所修饰名词的具体内容的，它与被修饰词语通常可以划等号;而定语从句是限制所修饰名词的，它的作用是将所修饰的名词与其他类似的东西区别开来：
We are glad at the news that he will come. 听到他要来这个消息我们很高兴。(news的内容就是that he will come，故that引导的是同位语从句)
We are glad at the news that he told us. 听到他告诉我们的这个消息我们很高兴。(that从句是限制the news的内容的，即我们高兴只是因为他告诉的这个news而不是其他的news，故that从句为定语从句)
2. 引导词的不同
what, how, if, whatever 等可引导名词性从句，但不引导定语从句。
3. 引导词的功能上的不同
that引导同位语从句时，它不充当句子成分，而引导定语从句时，它作为关系代词，要么充当定语从句的主语，要么充当定语从句的宾语。如上例 that he told us中的that就充当told的宾语。
4. 被修饰词语的区别
同位语从句所修饰的名词比较有限，通常有hope, wish, idea, news, fact, promise, opinion, suggestion, truth等，而定语从句所修饰的名词则非常广泛。 另外，when和where 引导定语从句时，通常只修饰表示时间和地点的名词，而它们引导同位语从句时却不一定;又如why引导定语从句，它通常只修饰名词the reason，而它引导同位语从句时则不一定：
I have no idea when they will come . 我不知道他们什么时候来。(同位语从句)
I’ll never forget the days when I lived there.. 我永远不会忘记我住在那儿的日子。(定语从句)
We don’t understand the problem why this is the best choice. 我们不明白这个问题，为什么这是最好的选择。(同位语从句 )
The reason why he didn’t come to the meeting is that he is ill. 他未能来开会，原因是他生病了。(定语从句)
