表语是用来说明主语的身份、性质、品性、特征和状态的，表语常由名词、代词、数词、动词过去分词、动词的-ing形式、副词、介词短语、形容词、不定式和从句等来充当。
Lyne is an excellent student
Henry was an American businessman
Henry met an American businessman
The person stood in front of you just now is my headmaster.
I didn’t know that it was you at that time.
The door remained closed.
Mary’s daily job is cleaning the house.
The house is not only large but also beautiful.
When I went to your house, you were out.
No one was in the dorm, when she arrived.
My job is to teach you English.
The reason why he came late was that his clock didn’t work.
Position (位置)表语常位于系动词（be等词）之后，与主语共同构成主--系--表结构 (Subject-Predicative structure) 的句子。
Linking Verbs (连系动词)
除动词be以外，还有一些后面可接表语的特殊连系动词，如：look, smell, taste, sound, feel, fall, come, go（变成…）, become, grow（渐渐地变化）, turn(变成，一般用于颜色), appear, seem, get, keep, remain, stay等。
一、表语从句定义：表语从句的定义：表语从句在复合句中作主句的表语。表语从句和主语指同一内容，它对主语进行解释、说明，使主语的内容具体化。
The question is who will do it.
表语从句放在连系动词之后，充当复合句中的表语。
二、表语从句构成
（系动词） +引导词 +简单句
His suggestion is that we should stay calm
That is why she was late.
三、引导表语从句的关联词
【1】从属连词that，whether；that 在表语从句中不充当任何句子成分，也没有任何意义。
The trouble is that I have lost her address.
麻烦是我把她的地址弄丢了。
My question is whether he left ( or not ).
我的问题是他是否离开了。
The question is whether we should ask them for help.
The trouble is that he has never done the work before
The fact is that he hasn’t yet recover from illness.
The reason why he has to go is that his mother is ill in bed.
比较 that在定语从句中的用法。
There are some films that I’d like to see.
She is the only student that knows French.
结论:that 在引导定语从句时,指事物,也可指人,
在从句中作主语或宾语,作宾语时常可省略。
【2】.从属连词as, as if / though引导的表语从句
由as if 引导表语从句时要注意语态.若从句表示与现在事实相反,谓动用be 动词要用were
与过去事实相反用 had +过去分词
Li Lei is now in a new jacket.
He looks as if he were an American boy.
The girl is giving us a vivid description of the moon.
It seems as if she had been to the moon many times.
He looked just as he had looked ten years before.
It sounds as if someone is knocking at the door.
It looks as if it were going to rain.
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 disease soon
【3】because, why 引导的表语从句
(1) That’s because he didn’t understand me.
那是因为他不理解我。(强调原因）
(2) That’s why he got angry with me
那正是他对我生气的原因。（强调结果）
4.连接代词who, whom, whose, whoever, what,
whatever, which, whichever 引导表语从句
(1) The problem is who we can get to replace her.
问题是我们能找到谁去替换她呢。
Guilin is not what it used to be.
What she wants to know is which dress she should buy.
The question is what caused the accident.
That mountain is not what it used to be .
What he told you was what had been discussed at the meeting.
【4】连接副词where, when, how
The question is how he did it.问题是他如何做此事的。
That is where he was born. 那就是他出生的地方
That is where Lu Xun used to live.
That is why he didn’t pass the exam.
四. 使用虚拟语气的表语从句(if不可以引导表语从句)
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等。
My suggestion is that we (should) start early tomorrow.
The question is whether we will have our sports meet next week.
The reason why he failed is that he was too careless.
The problem is who we can get to take the place of John.
The question is when he can arrive at the hotel.
The question is whether the enemy is marching towards us.
It looked as if he had understood this question.
The question is who will travel with me to Beijing tomorrow.
The question is why he cried yesterday.
注意点1：if 不能引导表语从句
注意点2：主句主语为reason, 只能用that引导表语从句，不可用because.
注意点3：如果从句是特殊疑问句，用陈述句语序
A：表语从句一定要用陈述语序
B 不可以用if，而用whether 连接表语从句(as if 例外）。
C 不像宾语从句，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。
【三】宾语从句：宾语从句在主从复合句中起宾语的作用，是一种名词性从句，既可作谓语动词的宾语，也可作介词、非谓语动词（动词不定式、动名词、分词.形容词）的宾语根据引导宾语从句的不同连词，宾语从句可分为三类。
1. 由that引导的宾语从句。that只有语法作用，没有实在的意义，在口语
和非正式文体中可以省略。例如：
He said (that) he wanted to stay at home.
She doesn’t know (that) she is seriously ill.
I am sure (that) he will succeed.
2. 由连接代词who, whom, whose, what, which和连接副词when, where, why, how引导的宾语从句。这些连接代词和连接副词在宾语从句中充当某个成分。例如：
Do you know who (whom) they are waiting foe?
He asked whose handwriting was the best.
Can you tell me where the No.3 bus stop is?
I don’t know why the train is late.
3. 由if或whether引导的宾语从句。if和whether在句中的意思是“是否”。例如：
I want to know if (whether) he lives there.
He asked me whether (if) I could help him.
（二）宾语从句的语序
宾语从句的语序应为陈述句的语序。例如：
I hear (that) physics isn’t easy.
I think (that) you will like this school soon.
Can you tell me how I can get to zoo?
Please tell me when we’ll have the meeting.
（三）宾语从句的时态
1. 如果主句的时态是一般现在时，宾语从句该用什麽时态就用什麽时态。
如： I don’t think (that) you are right.
Please tell us where he is.
Can you tell me how I can get to the railway station?
2. 如果主句的时态是一般过去时，宾语从句只能用相应的过去时态（一般过去时， 过去进行时， 过去将来时，过去完成时）。例如：
He asked what time it was.
He told me that he was preparing for the sports meet.
He asked if you had written to Peter.
He said that he would go back to the U.S. soon.
3. 如果宾语从句所陈述的是客观真理，其时态常用一般现在时。例如：
Our teacher said that January is the first month of the year.
Scientists have proved that the earth turns around the sun.
4.当主句谓语动词是think、believe、imagine等时，后面的宾语从句要表示否定意义时，要通过主句的否定式来实现，即否定主句中的动词。 e.g. 我认为他明天不会来。
（wrong）I think he will not come tomorrow.
（right）I don’t think he will come tomorrow.
某些形容词后面也可有宾语从句,这些形容词有:sure、certain、glad、pleased、happy、afraid、surprised、satisfied等。 e.g. I’m sure you can learn English well.
以上是你需要的，希望采纳，谢谢！
