2.何为表语从句：
表语从句是在复合句中作表语的名词性从句，放在系动词之后， 一般结构是“主语+系动词
+表语从句”。
3.可接表语从句的系动词：
①be动词，基本包括五个：am, is, are, was, were. （单独出现）
②感官动词，即表示感觉的一些动词，一般可以翻译成“……起来”，这些词大概有：look, sound, smell, taste, feel, em, appear; 分别表示：“看起来”、“听起来”、“闻起来”、“尝起来”、“摸起来/感觉起来”、“感觉似乎”、“显得似乎”。
3 表示“变与不变”类的词，这些词大概有：变得：become, get, turn, grow; 保持：keep, hold, stay, stand; 仍然：remain.
4.表语从句的分类：
1. that 引导的表语从句： that仅起连接作用，无意义，在句中不作任何成分，通常不能省略。这种从句往往对主句主语的内容起进一步解释的作用。其基本结构为“主语+连系动词+that从句” 。
The trouble is that she has lost his address. 麻烦的是她丢了她的地址。
The result is that many of them become fat. 结果是他们中很多人变胖了。
The reason why I didn’t attend the conference was that I was too busy. 我没有出席会议的原因是我太忙了。

2. wh- 引导的表语从句：
(1) whether 引导的表语从句：连接词whether起连接作用，意为“是否，究竟，到底”（注意：if 不能引导表语从句），在句中不作任何成分。
The question is whether that man will turn up in time.问题是那个人是否会及时出现。
The question is whether it is worth doing. 问题是这件事是否值得做。
(2) 连接代词引导的表语从句：连接代词what, which, who, whom, who等除了在句中起连接作用外，还在从句中充当主语、宾语、表语、定语等，且各有各的词义。分词作定语
The problem is who is really fit for the hard job. 问题是谁才真正适合这份艰苦的工作。
密友是什么意思 Tom is no longer what he ud to be. 汤姆不再是以前的汤姆了。
That is what he is worried about. 那就是他所担心的。
(3) 连接副词引导的表语从句：
连接副词when, where, how, why等除了在句中起连接作用外，还在从句中充当时间、地点、方式、原因状语，本身具有词义。

This is how she did it. 她是这样做的。
That is why he was late. 那就是他迟到的原因。
3. acesc其他连词（词组）引导的表语从句：
(1) becau引导的表语从句：becau引导表语从句通常用于“This/That/It is/was becau…”结构中。
(2) as if/though引导的表语从句：常置于感官系动词look, em, sound等后面，常用虚拟语气，表示不大可能存在的动作或状态。
I was late for school this morning. That’s becau I stayed up too late last night. 我今天早上上学迟到了，因为我昨晚熬夜太晚。
2012成都中考 The elephant feels as if/though it were a wall. 大象摸起来像一堵墙。
4.表语从句注意事项：
①当主句的主语是表示建议、命令、要求等的名词suggestion, request, proposal时，那么表语从句应该用虚拟语气，即谓语动词用“should + 动词原形”，should可省略。例如：
His suggestion is that we (should) climb all the way to the top of the hill.他的建议是我
们一路爬到山顶。
②在句型 “The reason (why)… is that…”中，that引导表语从句，此处的that不能换成becau；而在句型 “It/This/That is/was becau…”的表语从句中，becau也不能替换成that.
The reason why he was so late is that it was raining hard then. 他来这么晚是因为那时正下着大雨。
It’s just becau he doesn’t know her. 这仅仅是因为他不认识她。
