注意：　宾语从句一般用陈述语气，但是，当主句的谓语动词为advise，insist(坚决主张)，suggest(建议)，require，request，order等表示请求、命令，要求、主张的动词时，从句谓语要用虚拟语气，即用“should＋动词原形”(should往往可以省略)
She insisted that he (should) go there with her.
她坚决要求他跟她一起去那儿。
表语从句
表语从句在复合句中作表语，出现在连系动词之后，一般结构为“主语＋连系动词＋表语从句”。
可接表语从句的连系动词有be，look，remain，seem，sound等。
The question is whether we can finish the work in time.
问题是我们是否能及时完成这项工作。
You look as if you slept badly.
你看上去仿佛没睡好觉。

注意：　
(1)表语从句实际上是对主语进行补充说明，从句表达的是主语的内容。
The fact is that he didn’t notice the car until too late.
事实是他注意到汽车时已经太晚了。
(2)主句的主语是名词idea，advice，suggestion，order，request，requirement等时，表语从句应用虚拟语气，即谓语动词用“(should＋)动词原形”。
My suggestion is that we (should) have a discussion about this matter instead of setting it aside.
我的建议是我们应当讨论一下这个问题，而不是把它放在一边。
同位语从句
在复合句中作同位语的从句称为同位语从句。同位语从句是名词从句的一种, 它在句中起解释说明的作用。同位语从句一般放在fact, news, idea, truth, hope, problem, information, belief, thought, doubt, promise, question等名词的后面, 对前面的名词做进一步的解释, 说明前面名词的具体含义。引导同位语从句的词有: 连词that, whether; 连接副词how, when, where; 连接代词what, who, which, whose等。如：
The announcement that a new airport was to be built nearby aroused immediate opposition.
要在附近建造新机场的通告马上引起了反对。
5
注意：(1)为了保持句子平衡, 同位语从句有时可以不紧跟在它所说明的名词后面。如：
The story goes that William Tell killed the tyrant with an arrow.
传说威廉·泰尔用箭射死了暴君。
Suddenly the thought came to me that he could go blind.
突然我有一种顾虑: 他可能会失明。
(2)在表示建议、命令、请求、主张、目的、愿望等名词后面的同位语从句中, 谓语动词必须采用虚拟语气结构, 即“(should) + v.”。 如：
He gave orders that the work (should) be started immediately.
他指示要立即开始工作。
Her suggestion is that we (should) give up the plan.
她建议我们放弃这个计划。
