这是一份2022届高考英语语法复习 名词性从句之表语从句学案，共5页。
表语从句1． 概念：
表语从句放在连系动词之后，充当复合句中的表语．表语从句（Predicative Clause）就是指一个句子作为表语，说明主语是什么或者怎么样，由名词、形容词或相当于名词或形容词的词或短语充当，和连系动词一起构成谓语．
2． 结构：
主语+关联词+简单句
引导表语从句的词有从属连词that、whether、as though（if）；关系代词who， what， which， whom， whose， whatever， whoever， whomever， whichever等；关系副词when， where， why， how， however， whenever， wherever等．可以接表语从句的连系动词由be， look， remain， seem等．That引导表语从句时，在口语中，间或可以省略．
The trouble is that we are short of money．困难是我们资金短缺．
That is why stone walls are used instead of fences around New England fields．这就是为什么在新英格兰用石头墙而不用栅栏的原因．
At that time， it seemed as if I couldn't think of the right word anyhow．当时，我似乎怎么也想不出一个恰当的字眼来．
3． 用法：
1）． 可接表语从句的连系动词有be，look，seem，sound，appear等．
At that time，it seemed as if I couldn't think of the right word． 当时，我似乎怎么也想不出一个恰当的字眼来．
2）． 从属连词whether，as，as if / though引导的表语从句．

3）． because，why引导的表语从句．
That's why he got angry with me．那正是他对我生气的原因．（That's why…强调结果）
注意：what引导的主语从句表示结果或名词reason作主语时，后面的表语从句表示原因时要用that引导，不宜用because．
4）． 连接代词who，whom，whose，what，which，whoever，whatever，whichever
连接副词 where，when，how，why
例句：The problem is who we can get to replace her．问题是我们能找到谁去替换她呢．
The problem is how we can find him． 问题是我们如何找到他．
That's where I first met her． 那就是我第一次遇见她的地方．That's why I object to the plan． 这就是我反对这个计划的原因．5）． 从属连词that
The trouble is that I have lost his address．麻烦是我把他的地址丢了．
6）． 使用虚拟语气的表语从句
在表示建议、劝告、命令含义的名词后的表语从句，谓语动词需用"should+动词原形" 表示，should可省略．常见的词有：advice，suggestion，order，proposal，plan，idea等．
例句：My suggestion is that we （should） start early tomorrow． 我的建议是我们明天一早就出发．
