宾语从句和表语从句概念引入She doesn’t know (that) her father is seriously ill. 她不知道她父亲病得很严重。
Can you tell me how I can get to the railway station?你可以告诉我怎么去火车站吗？The problem is when they can get there. 问题是他们什么时候能到那儿。
The problem is whether we can replace her. 问题是我们能否替换她。
看到宾语从句四个字，你一定想“我学过了”，那么从上面4个句子中，你能够很容易地判断出前两个句子含有宾语从句，而后两个句子的黑体词部分就是表语从句了吧？本单元我们就从复习宾语从句开始，开始对名词性从句中的位置很相似的这两个从句进行一下小结吧。
语法讲解认识名词性从句1. 名词能作什么成分研究下面这个简单的句子：Lily, my sister, is a good girl, and she likes music.主语同位语系动词表语主语谓语宾语分析：此句是and连接的一个并列句，含有两个小句子，and前的句子的结构是“主系表”结构，and后是“主谓宾”结构。
其中主语、表语、宾语和同位语都是名词或名词词组（如a good girl）充当的，当然主语she是代词，而代词是用来代替名词，从而避免重复的词。
换句话说，名词在句子中可以作主语、宾语、表语和同位语。
2. 名词性从句的定义：在句子中起名词作用的句子叫名词从句(Noun Clauses）。
名词从句的功能相当于名词词组，它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能，名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。
现在，再次研究“概念引入”中的句子，你对名词性从句有了很清晰的认识了吧？3. 判断下面的名词性从句（划线部分）是什么从句。
英语必修3第三单元语法宾语从句和表语从句讲解------------------------------------------作者xxxx------------------------------------------日期xxxx英语必修3第三单元语法宾语从句和表语从句讲解、练习Unit 3 Grammar Noun Clauses 名词性从句名词性从句相当于名词，在复合句中可分别作主语、表语、宾语和同位语。
名词性从句可分为主语从句、表语从句、宾语从句和同位语从句。
一The Objective Clause 宾语从句在复合句中作宾语的从句称作宾语从句，可以作动词的宾语，也可以作介词和非限定动词及某些形容词的宾语。
引导宾语从句词有连词that，if，whether；连接代词who，whose，what，which；连接副词when，where，how， why等。
1)I think women can reach very high achievements in many fields of science.2) I wonder she remembered how many babies she had delivered.3) Do you know Jack was speaking to?4) He asked it was.5) Pay attention to the doctor said.6) Please tell me the earthquake took place.7) Will you tell me I can keep fit and healthy?做动词的宾语(1)大部分宾语从句直接跟在动词后：He doesn’t know where the post office is.(2)有些宾语从句前要有间接宾语：He told me what I should read．(3)如果宾语从句后面有宾语补足语，要使用形式宾语 it 而将从句放到补足语后面；I thought it strange that he failed to call me．(4)在think, believe, suppose, expect等动词之后的宾语从句中，如果从句谓语是否定含义，则将主句谓语动词think等变为否定形式。
表语从句解说及专项练习观点：表语从句是在复合句中作表语的名词性从句。
放在系动词以后,一般构造是“主语 +系动词 +表语从句”能够接表语从句的连系动词有be, look, remain, seem 等。
能够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 , smell3: stand , lie , remain ,keep, stay4: become ,get , grow , turn ,go ,come, run, fall5: prove, turn outThe trouble is that we are short of money. 困难是我们资本欠缺。
That is why stone walls are used instead of fences around New England fields.这就是为何在新英格兰用石头墙而不用栅栏的原由。
At that time, it seemed as if I couldn't think of the right word anyhow.当时,我仿佛怎么也想不出一个适合的字眼来。
指引表语从句的词：附属连词 that、 whether、 as though、 as if（ That 指引表语从句时，在口语中，间或能够省略。
）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。
由附属连词that， whether 指引的表语从句。
that 在指引表语从句时无词义，而whether 有词义，意为、“能否”。
表语从句1、概述用作表语的从句叫作表语从句，它位于主句中的连系动词之后。
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。
2、由从属连词that，whether引导的表语从句。
that在引导表语从句时无词义，而whether有词义，意为、“是否”。
这时主句的主语常常是些抽象名词，如question(问题)，trouble(麻烦)，problem(问题)，result(结果)，chance(可能性)，suggestion(建议)，idea(想法)，reason(理由)等。
表语从句对主句主语进行说明、解释，使主语的内容具体化。
The trouble is (that) she has lost his money. 麻烦的事是他丢了钱。
The question is whether we need more ice cream.问题是我们是否还需要一些冰淇淋。

名词性从句（宾语从句表语从句主语从句）讲解与练习六大基本句型1主系表句型----- be （连合动词do）2、主谓宾----- do（vt）3、主谓----- do(vi)----(不及物动词)4、主谓宾补----do(vt)5、主谓宾宾---do(vt) 记双宾语的动词一定要记。
6、There be (不及物动词do)--------be (不及物动词)宾语从句定义：在主谓宾句型的宾语的位置上把做为名词的宾语扩展成一个be句型或者do句型。
可以用下列公式举行表示：主语+谓语+从句。
宾语从句的连词① that , ②whether(or not)或if; ③which(whichever),who(whoever)，whom(whomever) ，whose(whosever)，what(whatever); ④when(whenever)，where(wherever)，why，how(however); ⑤ how many, how much, how long, how often，how soon宾语从句的形式：1、主谓宾句型的宾语从句: 作为名词的宾语扩展成一个be句型或者do句型。
He knows the newsHe knows that the teacher is in classroom2、主谓宾宾---do(vt) 句型的宾语从句，把直接宾语变为一个be或do句型。
He tells me the newsHe tells the news to meHe tells me that she is a teacherHe tells that she is a teacher to me3、主谓宾补句型的宾语从句需要it来做形式宾语I find Chinese important主谓宾补I find that we make a quick decision about this matter important主谓宾语从句补I find it important that we make a quick decision about this matter主谓形式宾语补宾语从句I think it necessary that we take plenty of hot water every day .我以为每天多喝开水是有必要的.I feel it a pity that I haven’t been to the get-together.我没去聚会,感觉特殊遗憾.I have made it a rule that I keep diaries.我每天写日记成了习惯.4、宾语从句的省略形式：某些形容词后面可以带宾语从句，其形式为sb+be+形容词+that宾语从句：这一类形容词通常是表示人物的心理，情绪等状态的形容词如：sure, certain, glad, please, happy, sorry, afraid, satisfied, surpriseda. I am glad (that) you helped me.b、I am sure (that) you can pass the exam.1、I am glad of your help.2、I am sure about your exam.剖析：上面句子中介词后面所跟成分都做介词宾语。
名词性从句在复合句中起名词作用的从句叫做名词性从句。
名词性从句的作用相当于名词，因此主语从句、表语从句、宾语从句和同位语从句分别作主句的主语、表语、宾语和同位语。
主语从句：Who will win the match is still unknown.宾语从句：I want to know what he has told you.表语从句：The fact is that we have lost the game.同位语从句：The news that we won the game is exciting.引导名词性从句的连接词可分为三类：连接词(不充当从句的任何成分)：that ,whether ,if连接代词：what, who, whom, whose, which, wh+ever连接副词：when ,where ,how ,whyObject Clauses 宾语从句一、宾语从句的概念：宾语从句在复合句中作主句的宾语。
位置：通常放在主句谓语动词（及物动词）或介词之后。
句子结构：主句+连词(引导词)+ 宾语从句e.g. She asked if these answers were right.We can learn what we do not know.He will talk to us about what he saw in the U.S.A.I don’t know where we will hold the meeting.通过观察，我们可以知道宾语从句的语序用陈述语序：连接词+主语+谓语+其他成分1)Could you tell me______.A. you will get here whenB. when will you get hereC. get here when you willD. when you will get here2) Mother asked his son what ______for lunch at school.A. did he hadB. does he hadC. he hasD. he had3) Pointing to the young plant, he asked me ____ that was the one we had seen in the picture.A. whatB. ifC. whereD. how二、连接词1、从属连接词(不充当从句的任何成分)：that ,whether ,if1）、I hear (that) he will be back in an hour.2）、I want to know if /whether he will go to the park with us用it做形式宾语的宾语从句时，it常可以放在动词think, find, consider, believe, feel, make等后作为形式宾语，而真正的宾语——that从句则放在句尾）（此时that一定不可以省略）I think it necessary that you should read English aloud.We heard it that she would get married next month.3、that从句位于句首时，that不可省略。
That he ever said such a thing I simply don’t believe.4、if 和Whether的区别1）、由连词if、whether 引导的表示“是否…”的宾语从句。
Whether,if 在从句中不做句子的成分，一般情况下，whether和if 可以替换。
例：I don’t know if/whether he will come tomorrow.2）、下面几种情况只能用whether①和不定式连(whether to do sth.)用作宾语时不用if引导.例：Whether to go there hasn’t been decided.They asked me whether to go shopping.②宾语从句中有or not时不用if引导.例：I don’t know whether the star will come or not.③在介词后面的宾语从句中不用if引导例：I’m thinking of whether we should go fishing.④宾语从句提前时：例：Whether this is true or not, I can’t say.练习：1. I asked her _____________ she had a bike.2. We’re worried about __________ he is safe.3. I wonder ______________ he is well.4. I don’t know ___________ or not he is well.5. I don’t know __________ to go.2、连接代词和连接副词连接代词：what, who, whom, whose, which, wh+ever 连接副词：when ,where ,how ,why 因为连接代词或副词连接主句和从句，并在从句中担任句子成分，具有一定的意义，不可省略。
Do you know what he said just now?I don’t remember when we arrived.I asked him where I could get so much money.Please tell me who (whom) we have to see.1. Wang Hai told me _______ he didn't go hiking yesterday afternoon.（how, why）2. Can you tell me ________ else is going to be on duty today?（who, whom）3. He always thinks ______ he can do better.（how, who）4. They don't know _________ we are going hiking. (when, what)5. I don't know ________ so many people crowding round him. (how, why)6. Do you know ________ shirt it is? (whose, who’s)三、时态1. 主句用现在时或将来时，从句可用任何时态，根据实际情况而定I know that he lives here.I know that he lived here ten years ago.I have heard that he will come tomorrow.2.如果主句是过去的时态（一般过去时，过去进行时），从句的时态一定要用相对应的过去的某种时（一般过去时，过去进行时,过去将来时，过去完成时）I knew who lived here.I saw that she was talking with her mother.He said that his father had gone to Beijing.3. 从句说明的是一般真理、客观事实、自然现象时，仍用一般现在时。
He told the boy that three and three is six.He told me that the earth moves around the sun.1. The young man asked _____ it's summer or winter.A. eitherB. thatC. weatherD. whether2. We don't know ______ they did it.A. howB. whoC. whatD. which3. The teacher asks us ____ Jim can come back on time.A. thatB. ifC. whenD. what time4. Does anybody know ______ we will have a sports meeting this weekend or not.A. ifB. whereC. whetherD. that5. Could you show me ________ ?A. how can I get to the stationB. where is the stationC. how I could get to the stationD. how I can reach the station8. Someone is ringing the doorbell. Go and see _______.A. who is heB. who he isC. who is itD. who it is10. He says that if it ______ tomorrow, he ____ fishing.A. will rain, won't goB. rained, wasn't goC. rains, won't goD. rain, will goPredicative Clauses 表语从句This is his job. This is what he does every day.（）（）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”。
系动词有那些呢? 常见的系动词分为三种：A．表示特征和状态：be, look, sound, taste, smell, seem, appear等B．表示由一类状态转为另一类状态：get, become, grow, turn, fall, go, come, run等C．表示某种状态的：remain, keep, prove, continue, stay等从句连接词分为三类：引导表语从句的连接词一般不省略。
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用横线画出表语从句：The question is whether we can rely on him.That is because we were in need of money at that time.He looked as if he was going to cry.That is why I was late.过观察，我们可以知道表语从句的语序也是用陈述语序注意：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，通常不可省略。
