表语从句位于主句系动词之后，可分为两类：be + that型从句和be + 疑问词型从句。
1. be + that型从句
例如：The fact is that we have no idea to solve this problem.
翻译：事实就是我们没办法解决这个问题。
例如：The reality is that the party must be cancelled because of the storm.
2. be+疑问词型从句
例如：The question is whether they will help us.
翻译：问题是他们会不会帮我们。
例如：The problem is why she didn't go back home directly.
翻译：麻烦就麻烦在为什么她没直接回家。
3. 表语从句使用陈述语序。
例如：The question is when he can arrive at the hotel.
翻译：问题是他什么时候能到酒店。
4. 主句主语是reason时，表语从句要用that引导，不可用because。但reasons作主语时，表语要用名词短语并列。
例如：The most common reasons for …… are 名词短语1，名词短语2 and 名词短语3。

主语+连系动词+句子作表语，是表语从句的常用句型。
表语从句使用的是正常语序；
例如：The question is when he can arrive at the hotel.
翻译：问题是他什么时候可以到达酒店。
在有表语从句的复合句中，主句时态和从句时态可以不一致；
例如：The question is why he cried yesterday.
翻译：问题是他昨天为什么哭了。
that在表语从句中不可以省掉。
例如：What I told him was that I would find him a good play.
翻译：我告诉他我会给他找一个好剧本。
It/This/That is because……，该句型是because 引导的表语从句.
eg.He was sent to hospital. That was because he was ill.他被送到医院，是因为他生病了。
此外，that，why同样可以引导表语从句，但that在句中没有词义，且不能省略；在内容上，why 强调结果，because强调原因。
eg. ①The reason was that you don't trust her.原因是你不信任她。
②He was ill. That was why he was sent to hospital.他病了，所以被送到医院来。
补充：下面的句子是原因状语从句在强调句中的表达，与表语从句不同：
It was because the weather was so bad that we stayed at home.正是因为天气不好，我们才呆在家里。（强调部分是because the weather was so bad，原句是: We stayed at home because the weather was so bad. ）
