2. 表语从句的构成
主语 + 系动词 + 引导词 + 简单句
This is why he did it.
What I want to say is that I am tired
表语从句放在连系动词之后，充当复合句中的表语。
可以接表语从句的系动词有：
1: be（being,been,am,is,are,was,were)
2: feel , seem , look, appear ,sound, taste , smell
3: stand , lie , remain ,keep, stay
4: become ,get , grow , turn ,go ,come, run,fall
5: prove, turn out
连接词：that / whether /as if /as though (if不引导表语从句)
连接代词：who / whom / whose / which / what
连接副词：when / where / why / how / because
表语从句
1. that
1) that 在从句中不担任句子成分，无实际意义，一般不能省略
2)在表“建议，劝说，命令”的名词idea, suggestion, request, proposal 等后面的表从句中，谓语动词用“should + 动词原形”，should可省略
My opinion is that it’s getting better and better.
My suggesstion is that we (should) start early tomorrow.
2.whether在表语从句中表“是否”，但不充当句子的成分。if “不能”引导表语从句。如: What the doctor really doubts is whether my mother will recover from the serious
言承旭公开认爱disease soon.
The question is whether it is worth doing.怎么开通qq黄钻
3.as if, as though 引导的表语从句
1)as if/though引导的表语从句常置于连系动词look, seem, sound, be, become等后面，
常用虚拟语气，表示不存在的动作或状态。
< It sounds as if/though somebody was knocking at the door.
2) 主语+连系动词（look/seem/appear……）+that/as if从句
*as if/as though引导的表语从句如果是事实，就用陈述语气；如果与事实不符，就用虚拟
语气(主句一般现在时，从句就用过去式，be的话变成were。主句是过去式，从句用过去完成时)。It looks as if he were her own father.(与事实不符)
Dark clouds are gathering. It looks as if it’s going to rain.
As /as if、as though
The situation is not ____ it seems to be.形势并不像外表所看到的那样。
She looks ____ ____ she is worried about her leader’s disease.她看上去很担忧她领导的病情。
It was ____ ____ he were mad.他好像疯了似的。
4.because
because引导表语从句通常只用于“This/That/It is because…”结构中。
My anger is because you haven’t written to me for a long time.
你为什么不来出席座谈会？是病了么？
Why were you absent from the forum? Was it because you were ill?
5.that, why 与because 引导表语从句时的区别
1）虽然三者均可引导表语从句，但that没有词义，而why 和because 有自己的意思；另外，虽然why和because 都可引导表语从句，但前者强调结果，后者强调原因。如：The reason was ____ you don’t trust her. 原因是你不信任她。
The fact is ____ they are angry with each other. 事实是他们生彼此的气。
He was ill. That’s ____ he was sent to the hospital. 他病了，所以被送到医院来。He was sent to the hospital. That’s ____ he was ill.他被送到医院，是因为他生病了。
填空: The reason why we didn't trust him is ______ he has often lied．
*reason 做主语时，表语从句只能用that引导, 不能用why 引导。句型结构为：
The reason (why…/for…)is /was that….
The reason is that……
他早上来晚的原因是他晚了一分钟而没赶上火车。
The reason ____ he was late was ____ he missed the train by one minute this morning
（当主语是reason时，表语从句要用that引导而不是because）
注意点1：主语为reason 时，表语从句连接词用that, 但以it, this, that 开头做主语的句子，则可用because。
The reason for his being late was ____ he missed the early bus.
She was late this morning. That was ____ she missed the early bus.
* The reason why he was late was ____ he missed the early bus.（why引同位语从句）例题2：
The reason why he failed is ________he was too careless.
A. because
B. that
C. for
D. because of
注意点2：主句主语为reason, 只能用that引导表语从句，不可用because.B
