之后，引导表语从句的词有连词that, whether, as if; 代词who, what, which; 副词when, where, how, why等，如：
The trouble is that she has lost his address. 麻烦在于她弄丢了他的地址 That is where he was burn. 这就是他出生的地方 This is how she did it.
这就是他如何做这件事的
It looked as if it was going to snow.
看起来似乎要下雨 2． That引导的表语从句
当表语从句为陈述句的语气时，用that来引导，that无任何意义，不充当任何句子成分，如：
The fact is that the child is lying.
事实是那个小孩在说谎
The trouble is that we are short of money.
问题在于我们缺钱
3． Whether引导的表语从句
当表语从句为不确定的语气时，用whether来引导，此时通常不可用if代替，如： The first question is whether it is true or not.
首要的问题是这是否是真的
It was uncertain whether he would come.
不确定的是他是否会来 4． Wh-疑问词引导的表语从句
当表语从句为疑问的语气时，用wh-疑问词来引导，要注意表语从句的语序为陈述语序，如：
The problem is how we could make him understand it. 问题是我们如何使他明白这些 The question is where we should go. 问题是我们该去哪
5． As if/ though引导的表语从句
He looks as if he were angry.
他看起来似乎非常生气
四、 同位语从句
1. 概述：
用作同位语的从句，叫做同位语从句。它一般跟在某些名词（如fact, idea, news, promise等）的后面，用以说明或解释前面的名词，引导同位语从句的词有连词that，连接副词how, when, where等，如： I have no idea when he will be back. 我不知道他何时会回来
We heard the news that our team had won. 我听到了我们队胜利的消息 2. That引导的同位语从句
在下列名词后可用that引导同位语从句：answer, belief, doubt, fact, hope, idea,
information, knowledge, law, news, opinion, plan, suggestion, thought, truth等，如： I have no idea that you were here. 我不知道你在这里
3. No idea+wh-疑问词引导的同位语从句
I have no idea where he has gone. 我不知道他去了哪里
She had no idea how she could do it. 她不知道她应该怎样做 4. 注意
1) 名词demand, proposal, suggestion等后的同位语从句要用虚拟语气，谓语为
“should+动词原形”或只用动词原形，如：
The suggestion that the plan (should) be delayed will be discussed tomorrow.
推迟那项计划的建议将在明天讨论
She refused the demand that he (should) do the work alone.
她拒绝了他单独做那项工作的请求 2) 同位语从句与定语从句的区别
同位语从句引导词无意义，不充当成分，但不可省略，同位语从句与其说明的名词或代词应为同一内容，但定语从句的引导词要在句中做成分，是对先行词的一个限定说明，如：
He told me the news that our team won.
他告诉我我们队取得胜利的消息（同位语从句） He told me the news that was very happy. 他告诉我的那个消息令人振奋（定语从句）
