what 在名词性从句中的用法
1．确定含义。what 引导名词性从句有两种含义：
（1）什么（2）……的人/事/物。例如：
1. I don't know what I should do with the problems. 我不知道该如何处理这些问题。（什么）
2. What you will do next is none of my business. 你下一步做什么不关我的事。（什么）
3. The teacher told us he wanted to take back what he had said. 老师告诉我们他想收回他说过的话。（……的话）
4. She is no longer what she used to be. 她不是过去的她了。（……的人）
2．确定成分。what 作“什么”讲，在名词性从句中作主语、宾语、表语或定语；作“……的人/事/物”讲，在名词性从句中作主语、宾语或表语。例如：
5. They don't know what happened.他们不知道发生了什么。（what 在从句中作主语，含义是“什么”）
6. What he says is not important.他所说的并不重要。（what 在从句中作主语，含义是“……的话”）
7. Do what you please.你爱干什么就干什么。（what 在从句中作宾语，含义是“……的事“）
8. Please tell me what you are doing here on earth! 请告诉我你究竟在这里干什么！（what 在从句中作宾语，含义是“什么”）
9. He is not what he was ten years ago.他不再是十年前的他了。( what 在从句中作表语，含义是“……人”)
10. It is the ability to do the job, not what she is , that matters. 重要的是（她）做这项工作的能力，而不是她是什么（人）。（what 在从句中作表语，含义是“什么”）
11. Are you sure what books he likes reading? 你知道他喜欢读什么书吗？（what 在从句中作定语，含义是“什么”）
注：what 作“……的人/事/物”讲时一般不作定语。
3．引导从句的性质。what 可以引导主语从句(例句2 和例句6)、宾语从句（例句1 和例句3）、表语从句（例句 4 和例句9）、同位语从句。再如：
The question what makes the matter worse has been puzzling me. 是什么使情况更糟了？这个问题一直在困惑着我。（what 引导的是同位语从句）
注：除了上述主要用法外，what 还有两种其它用法。
a. 关系形容词用法：作定语，意为：所……的，任何……的（= as much/many as；the... that；any... that）。例如：
I gave him what books (=any books that/the books that) I had. 我把我所有的书全给他了。
I will give you what help (=any help that/as much help as)I can. 我愿尽力帮助你。
Lend me what money (= as much money as)you can. 你能借多少钱就借给我多少。
b. 感叹词用法：作定语，意为：多么（多用于简单句中的感叹句中）
What a fool you are! 你多傻！
What a good idea! 多妙的主意啊！
What happy boys! 多幸福的孩子啊！
What a pity! 真遗憾！
What 和that 在名词性从句中的用法区别
名词性从句包括主语从句、宾语从句、表语从句、同位语从句四种。名词性从句是高二学生必学的重要英语语法之一。在学名词性从句时，学生经常为What 和that 在句中的用法而困惑。下面是我在教学实践中对这一知识的总结，仅供同学们参考：What 和that 都可以引导名词性从句。但他们在句子中的语法功能截然不同。一．在引导名词性从句时，从属连词that一般要注意三个不（three nos）：
1．不省略（no ellipsis）
当从属连词that引导主语从句、表语从句和同位语从句时，that不省略。
Eg. 1) That he was able to come made us happy. (That 引导主语从句不可省略)
2)The truth is that I didn’t go there. (that引导表语从句不可省略)
3)The news that our team has won is true. (that引导同位语从句不可省略)
但在非正式文体中that 引导宾语从句时可以省略，除下列两种情况外：
that在宾语从句中不能省略的情况.
(1). 在主+谓+it(形式宾语)+宾补+that，从句(真正宾语) 的句型中不省略.
Eg: 4) He made it quite clear that he preferred to study English.（that不可以省略）
他很明确地说他宁愿学习英语。
(2). 由连词and连接的两个由that引导的宾语从句中, 则第二个宾语从句前的that 不省略。
Eg: 5) He told me that he would come and that he would come on time.（第一个That 可以省略，但第二个that不可以省略。)他告诉我他将来而且他将准时来。
2．不作成分（no component）
that 在名词性从句中不作任何句子成分。
Eg. 6)Sydney kept his promise that he would always do anything he could for Lucie to make sure of her happiness.（that在句中引导同位语从句，但在句中不作任何成分）
7))That you don’t like him is none of my business. (that在句中引导主语从句，但在句中不作任何成分，也不省略）
3．没词义（no meaning）
that 在名词性从句中没有汉语意思。
Eg. 8)That she is a rich woman is known to us. (that在句中引导主语从句，但在句中没有汉语意义)
她是一个很有钱的女子，这一点我们都知道。
9）The thought that he might fail in the exam worried him. (that在句中引导同位语从句，但在句中没有汉语意义）
他也许会考试失败，这一想法使他很担心。
定语从句中的that和which的用法 引导定语从句的关系代词有：that（指人或物）,which （指物）,who (指人）.指人时可用that或who ；指物时可用that 或which 。 That和which在从句里都可以做宾语和主语，做宾语时可以省略。指物时，两者一般可以互换，但在下列情况下只能用that： 1）当先行词是all ,any ,anything ,everything ,nothing 或被它们修饰时.例如： Is there anything that I can do for you 有什么可以为你做的吗? All that can be done must be done . 凡是能做的都必须做. 2）当先行词被形容词的最高级或序数词修饰时.例如：That is one of the most interesting books that are sold in the bookshop . 那是这家书店出售的最有趣的书之一. The first thing that we should do is to get some food . 我们该做的第一件事是弄点吃的. 3）当先行词有：the only ,the very ,the same ,the last 等修饰时.例如：
My necklace is not the only thing that's missing . 我的项链不仅是丢掉的东西. 4）当主句以who或which开头时,定语从句中引导词用that ,不用which 或who .以避免重复.例如： Who is the girl that is wearing a red coat 正穿一件红色外套的女孩子是谁? 5）当先行词既有人又有物时,用that .例如： The writer and his novel that you have just talked about are really well known . 你刚才谈起的那位作家以及他的小说确实很著名. 请注意: 以下几种只能使用which的情况: 1.引导非限制性定语从句，用which。 2.在“介词＋关系代词”结构中，关系代词必须用which。 如：The house in which we live is very large. 我们住的房子非常大。 This is the reference book of which the teacher is speaking. 这就是老师正在谈及的那本参考书。 注意：如果介词不放在修饰事物的限定性定语从句的句首，which就可换为that，例如：This is the question which/that we've had so much discussion about. =This is the question about which we've had so much discussion.
1 名词 一般来说名词主要考查： 1．可数名词复数构成的规则及不规则变化。 2．可数名词和不可数名词的判断与用法——对比。 3．名词的所有格，包括’s所有格，…of…所有格和双重所有格的用法。 4．名词作定语和名词构成的习语及用法等。 5．名词的词义辨析。 2名词性从句有哪些引导词？并试着说明他们的用法。 热点一．语序与时态： 能力激活1： 想一想：名词性从句中的语序要注意什么问题？ 1. No one can be sure _____in a million years. A. what man will look like B. what will man look like C. man will look like what D. what look will man like 3. I don’t know when_____, but if he _____, I’ll let you know. A. he comes , will come B he will come , will come C he will come, comes D he comes, comes 小结1：不管主句是肯定句、否定句还是疑问句,名词性从句总是使用_____________. 观察与比较：I’m not sure if he will come ,but if he comes ,I’ll let you know . 小结2：主句是现在时态，宾语从句用_________________. 感悟疑点: He has come, but I didn’t know that he _____ until yesterday. A is coming B will come C was coming D wasn’t coming 能力激活2： 想一想：宾语从句中的时态应如何与主句时态保持相应的一致？ 1.The police found that the house _____ and a lot of things _____． A．has broken into; has been stolen B．had broken into; had been stolen C．has been broken into; stolen D．had been broken into; stolen 2.We were all surprised when he made it clear that he _____ office soon．(NMET’93) A. leaves B. would leave C．left D．had left 小结1: 主句是过去时态时，宾语从句用_________________. 但如果表达真理性的，则用现在时。疑点：3．Mum is coming .What present do you expect _____for your birthday? A. that she has got B. that has she got C. she has got D. has she got 思考：句中出现插入语时，语序该怎么办？ 疑点观察、总结与拓展： 4. What do you think we should do to solve the problem of air pollution in cities? 5. Where do you suppose he can be? 小结2：以上句子体现了何种句式结构？_____________________________ 小试牛刀： 6. Rose looks worried. What do you think ____________________(她该怎么办)? Exception :7．He went up to see ________ with her.
名词性从句用法详解 一、概说 名词性从句，即指性质相当于名词的从句，它包括主语从句、宾语从句、表语从句和同位语从句。从高考的考查的实际情况来看，名词性从句考得最多的是宾语从句，其次是主语从句，再次是表语从句，而同位语从句则很少考查。 二、名词性从句的一般引导词 1. 连接词that 只起连接作用，没有任何意思，也不充当句子成分，在宾语从句中可省略，但引导其他名词性从句时通常不省略。如： I hope (that) you enjoy your holiday. 希望你假期过得好。 That he likes you is very obvious. 很显然他喜欢你。 2. 连接词whether 也不充当句子成分，但有自己的意思，表示“是否”；引导宾语从句时，可换成if，但引导其他名词性从句时不能换成if。如： He asked whether [if] I would show him the way. 他问我是否可以给他带路。 Whether it will do us harm remains to be seen. 是否对我们有害还要看一看。(引导主语从句，不能用if 代替whether) 3. 连接代词who(m), whose, which, what 等，均有各自的意义，在从句中作主语、宾语、定语等。如： That’s why she wanted to leave. 这就是她想离开的原因。 When we arrive doesn't matter. 什么时候到没有关系。 Tell me which one you like best. 告诉我你最喜欢哪一个。 4. 连接副词when, where, why, how 等，也各自有自己的意义，在从句中作状语。如： The question is how we should carry out the plan. 问题是怎样执行这个计划。 When she’ll be back depends much on the weather. 她什么时候回来在很大程度上要看天气。 Why he did it will remain a puzzle forever. 他为什么这样做将永远是一个谜。 三、名词性从句的重要引导词 1. what 用于引导名词性从句是一个十分重要的引导词，它可引导主语从句、宾语从句和表语从句，但不用于引导同位语从句。它引导的名词性从句有两个意思是：一是表示“什么”，带有疑问意味；二是表示“…所…的”，相当于一个先行词后接一个关系代词。如： I don’t know what you want. 我不知道你想要什么。 I don’t know what you want is this. 我不知道你所想要的是这个。 2. what 引导名词性从句时可用作限定词，其后修饰名词。如： I gave him what books I had. 我把我所有的书都给他了。 He gave me what money he had about him. 他把身边带有的钱全给了我。 注：what 后的名词可以是复数名词或不可数名词，但通常不能是单数可数名词，并且后接不可数 名词时，有时可有little修饰，两者的区别是：what+不可数名词=所有的都，what little+不可数名词=虽少但全部。如：
what引导名词性从句的五种用法 一、用法归纳 1. 表示“……的东西或事情”： They’ve done what they can to help her. 他们已经尽力帮助了她。 He saves what he earns. 他赚多少，积蓄多少。 What Mary is is the secretary. 玛丽的职务是秘书。 2. 表示“……的人或的样子”： He is no longer what he was. 他已经不是以前的那个样子。 He is what is generally called a traitor. 他就是人们通常所说的叛徒。 Who is it that has made Fred what he is now? 是谁把弗雷德培养成现在这个样子的？ 3. 表示“……的数量或数目”： Our income is now double what it was ten years ago. 我们现在的收入是10年前的两倍。 The number of the students in our school is ten times what it was before liberation. 现在我校学生的数量是解放前的10倍。 4. 表示“……的时间”： After what seemed like hours he came out with a bitter smile. 似乎过了几个小时他才苦笑着出来。 The young girl was too frightened to speak, standing there for what seemed like hours. 小女孩吓得不敢说话，在那儿站了几个小时。 5. 表示“……的地方”： This is what they call Salt Lake City. 这就是他们称为盐湖城的地方。 In 1492, Columbus reached what is now called America. 1492年哥伦布到达了现在所称的美洲大陆。 二、用法说明 (1) 这样用的what相当于“先行词+关系代词”，所以其前不能有先行词： 你喜欢什么就拿什么吧。 正：You can have what you like. / You can have everything (that) you like. 误：You can have everything what you like. (2) 有时what 可用作限定词，其后修饰一个名词： I gave him what books I had. 我把我所有的书都给他了。 He gave me what money he had about him. 他把身边带有的钱全给了我。 (3) What 后的名词可以是复数名词或不可数名词，但通常不能是单数可数名词： 误：I gave him what book I had.
THAT用法总结 第一、that 用作形容词（后接复数名词时用those） 它用来指已被提到的人或物；也可表对比，指两个中较远的那个。 What about that book you borrowed from me last month？ 请注意，that 有时候在句子中具有喜欢或轻蔑等感情色彩。 that little son of his 他那个小宝贝儿子 That George！乔治那家伙！（含有轻蔑语气） 第二、that 用作代词。 1. that 用作指示代词（复数形式是those），其指代意义同形容词用法，同时它还可以用作定语从句中的先行词；还可为了避免重复，代替前述名词。 .that用来替代前面提到的特指的事物,所代替的名词可以是可数名词,也可以是不可数名词.代替可数名词可以用the one替换.但其前面不可用任何限定词修饰.例如: 1)The population of China is larger than that of Japan.(that代替不可数名词population,不可用the one替换) 2)The headteacher in your class is younger and more active than that in theirs.(that代替可数名词headteacher,可用the one替换) that 代替指物的单数可数名词或抽象不可数名词，一般是特指的 those 代替指人或指物的复数名词，一般是特指的=the ones one 代替指人或指物的单数可数名词，一般是泛指的 ones 代替指人或指物的复数名词，一般是泛指的 That is what he told me. What is that (which) you have got in your hand? The price of rice is higher than that of flour. 2. that 用作关系代词，引导限制性定语从句。先行词可人可物，用法相当于who或which。（但是在下列情况下多用that：先行词既有人又有物时；先行词有形容词最高级、序数词、不定代词、very，only等修饰时；先行词是不定代词时）He talked about the teachers and schools that he had visited. I think it one of the most wonderful films that the film company has ever produced. She has little information that is useful for our research. Is there anything that I can do for you? 请注意，that 在定语从句中作宾语时通常可省略。 The books (that) I sent you will help you in your studies. 第三、that 用作连词，引导名词性从句,状语从句和强调句。 1. that名词性从句。 ①引导宾语从句。及物动词后的引导词that可省略。 I didn't expect (that) he could win the championship. The teacher pointed out that Tom was not working hard enough.
高一语法专题：名词性从句 在句子中起名词作用的从句叫名词性从句。名词性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，因此根据它在句中不同的语法功能，名词性 从句又可分为主语从句、宾语从句、表语从句、同位语从句。 引导名词性从句的词叫做连接词，包括：1. 连词（在名词性从句中只起连接作用，不 作成分） 2. 连接代词（在名词性从句中作主语、宾语 或表语） 3. 连接副词（在名词性从句中作状语） I 主语从句：是在主句中作主语的从句。它由连接词引导，通常位于谓语动词之前。 连接词：
1. 连词：在从句中不充当任何成分，常见的引导主语从句的连词有that, whether。 That he got the first prize excited him much. 他获得一等奖一事使他非常兴奋。 It is doubtful whether we can get there on time. 我们能否按时到达那儿还不确定。 1）that引导的主语从句：在从句中不作任何成分，也没有实际意义。一般情况 下that不可省略。 That light travels in straight lines is known to all. 众所周知，光沿直线传播。 That you don't like him is none of my business. 你不喜欢他不关我的事。 2）whether引导的主语从句：常置于句首，表示“是否”之意；
Whether he can finish his task on time is of great importance. 他是否能按时完成任务非常重要。 Whether you can succeed or not depends on how hard you work at it. 你能否成功取决于你努力的程度。 2.连接代词：在从句中起名词或代词的作用，常作从句的主语、宾语、表语或定语，有具 体意义且不能省略。常见的连接代词有who, whom, whose, what, which, whoever, whomever, whatever, whichever。 What we should do with the problem is undecided. 我们如何处理这个问题还未作出决定。（what引导主语从句，不表疑问意义） Whom the letter was from is still unknown.
名词性从句归纳 一、名词性从句概说、结构与功能 名词性从句是起名词作用的从句，其功能相当于名词词组，在复合句中可作主语、宾语、表语和同位语。与之对应的名词性从句分别为主语从句、宾语从句、表语从句和同位语从句。 二、主语从句 1、主语从句的类别 ●以从属连词that 引导的主语从句。（从句位于句首，that通常不省略） → That she will come to the conference has excited every one of us. ●以从属连词whether 引导的主语从句。（从句置于句首时一般不用if来代替whether） → Whether we’ll go outing depends on the weath er. ●以连接代词（what, whatever, who, whoever, which, whichever等词）引导的主语从句。 → Whoever will be in charge of the project hasn’t been decided yet. 【注】what 与that在引导主语从句时，what 不但起连接作用，而且还有具体意义，意为“所…的”，相当于the things that结构；而that则无词义。即如果从句中不缺少主语或宾语时，选择that，否则用what。 ●以连接副词（when，where, how, why 等词）引导的主语从句. → When the new road is open to traffic has not been made clear. 2、用it 作形式主语的主语从句 注：以下几种特殊情况必须用it作形式主语： ⑴ It is + adj. + that 从句 常见的形容词有：necessary，right，likely，wrong，important，certain，clear，obvious，strange 等。 → It is likely that there will be a snowstorm tomorrow. ⑵ It is + noun + that 从句 常接这种句型的名词有：a pity, a shame, good news, a fact, an honor, a wonder, no wonder 等。 → It is a pity that you didn’t attend the lecture [讲座] yesterday. ⑶It is + 过去分词
that和which引导的定语从句：微习题 用which 或that填空： 1. You should hand in all _________you have. 2.Please send us all the information ________you have about the candidate for the position. 3.

He lived in a big house, in front of _______ stood a big tall tree. 答案： 1. that 2. that 3. that 4.that 5. that 6. that 7. that 8. that 9. that 10. that 11. which 12. which 13. which 14. which 15. which
一、在名词从句中连接词which 有两种词性, 常用来引导宾语从句： 1. [连接代词] 哪个 1）用作从句的主语，如： He wanted to know which was on the table. 他想知道哪一个在桌子上。 2) 用作从句的宾语，如： He asked me which I liked best. 他问我最喜欢哪一个。 2. [连接形容词]放在名词前作定语，表示“哪个XX，哪些XX”，如： Do you wnow Which country is the largest? 你知道哪国家一个最大? Could tell me which children made him still more angry. 能告诉我那些 孩子使他更加生气了。 二、which 除引导上述宾语从句外，还可以引导主语从句和表语从句。 1. 主语从句(常用形式主语it) It was clear which children made him still more angry. 显而易见那些孩子使他更加生气了。 It is known to us which he liked best. 众所周知他最喜欢哪一个。 2. 表语从句 That was which children made him still more angry. 那就是那些孩子使他更加生气了。 This is which he liked best. 这就是他最喜欢哪一个。 三、which 与what 的区别 用在名词从句中，which 意思是“哪一个/那一些”，what 意思是“所...的”，后者等于“先行词+关系代词”，如你的补充问题就需要选择what： It's quite different from what I read last month. = It's quite different from (the one that) I read last month. 这本书与我上周所读过的那一本区别很大。 1.that在所有名词性从句中无成分无意义。 2.which强调哪一个，有一个选择的范围。 从句中from后边缺宾语，所以要选择的是宾语从句的引导词，首先that引导宾语从句时，不做介词宾语（除了in,except,but) 其次read后边缺宾语，也就是从句中缺成分，参见上面第一条，所以排除that.B选项which指哪一个，这里
名词性从句用法归纳Mar 3, 2011 名词性从句包括主语从句，宾语从句，表语从句和同位语从句。它们的作用相当于名词，因此为名词性从句。 一. 主语从句 引导词：连词that, whether; 连接代词who / whoever，what / whatever，which ； 连接副词when, where, how, why。 1.That 1) That computers have changed our life is clear to everyone. = It’s clear to everyone that computers have changed our life. 2) That children must go to school is accepted by us all. = It’s accepted by us all that children must go to school. 3) That you are from Tangshan can be judged from your accent. = It can be judged from your accent that you are from Tangshan. 结论：that 无含义, 不做成分。 2. what 1）What I can’t understand is why he is often absent from school. 2）What parents say and do has a life-long effect on their children. (07 陕西) 3）What matters most in learning English is enough practice. (07 全国） 结论：what “所…的”，在从句中做成分。 3. whatever 1)Whatever was said here must be kept a secret. 2)Whatever David says sounds right to Helen. 3)Whatever I may do is supported by my parents. 4. whoever 1)Whoever works hard is respected by others. 2)Whoever breaks school rules will be punished.
定语从句中 which,that 的用法与区别 只能使用that的情况： 1.当先行词是nothing, something, anything, all, each等不定代词时。 e.g. Do you have anything that is important to tell me? 2.当先行词被all, any, some, no, not, every, each等修饰时。 e.g. I have some books that are very good. 3.当先行词被形容词最高级、序数词(包括last, next等)所修饰时。 e.g. This is the first book that I bought mysel f. The biggest bird that I caught is this bird. 4.主句是以which或who开头的特殊疑问句时 e.g. Which is the bike that you lost? 为了避免重复时用that Who is the woman that was praised at the meeting. 5.当先行词在从句和主句中都作表语时,无论先行词是人还是物. China is no longer the country that she was. 6.如有两个定语从句,其中一个已用which引导,另一个宜用that . Edison built up a factory which produced things that had never been seen before. 7.在there be句型中,只用that. He asked for the latest book (that) there is on the subject. 8.当先行词被the very, the last, the next, the only，the same 等词修饰时。 e.g. This is the very book that I lost yesterday. 9.当先行词又有人又有物时。 e.g. I won’t forget the things and the persons that I saw. 10. 先行词被all, every, no, any, little, some, much等修饰时。 I’ve read all the books that are not mine. 只能使用which的情况。 1、非限制性定语从句(即通常用逗号与主句隔开，如果去掉逗号，整个句子仍能表达完整的意义的定语从句)中。 e.g. Mary has a book, which is very precious. 2、在介词之后。 e.g. This is a house in which lives an old man. 3、当主句中的主语被that修饰时。 e.g. That dog which I found in the street belongs to Mary. 4. 非限定性定语从句修饰的是前面的整个句子，而且关系代词和关系副词前面有逗号, 用which开始的定语从句修饰前面半句 e.g. He will wear no clothes, which will distinguish（区分，辨别）him from his fellow men.

浅谈that在从句中的用法 摘要：that在英语中是一个非常常见的单词，它之所以常见，不仅仅是 因为它是一个在生活中常常要用到它，更因为它的用法相当的多。因此，同学们在使用that这个单词时，总会出现这样那样的问题，特别是that 在从句中的使用,更是令同学们常常模棱两可，分辨不清。 关键词：that 用法 1.主语从句2. 宾语从句 3. 表语从句 4.同位语从句 5. 目的状语从句6.定语从句 that在英语中是一个非常常见的单词，它之所以常见，不仅仅是因为它是一个在生活中常常要用到的字，更因为它的用法相当的多。因此，同学们在使用that这个单词时，总会出现这样那样的问题，特别是that在从句中的使用,更是令同学们常常模棱两可，分辨不清。但考试中又常出现，让我们和学生都比较头痛。我觉得要解决这个问题，首先要让学生弄清that在所引导的从句中它的词性，然后结合实例分析，这样学生就可一目了然了。具体来说，that可作连词或关系代词。具体的作用如下： 一．that引导主语从句(subject clauses)，在句中充当主语的成分。that在句中无实义，但放在句首时不能省略： a．that the attempt to save her had succeeded became widely known. b．that they did not tell us about their problems is a pity. 这种结构主要是对that从句的内容进行强调，属正式文体，that the attempt to save her had succeeded和that they did not tell us about their problems在句中都分别作了主语。但为了避免显得头重脚轻，常把that从句移到句子后面，而把it放在句首，作形式主语，此时that可以省。上面两个句子就可改为: a. it is widely known (that) the attempt to save her had succeeded b. it is a pity (that) they did not tell us about their problems.
名词性从句 名词性从句相当于名词，可分别作主句的主语、表语、宾语和同位语。因此，名词性从句厅分为主语从句、表语从句、宾语从句和同位从句。 （一）引导名词性从句的连接词 1、连接代词：who, whose, whom, what, which。有词义，在从句中担任成分，如主语、表语、宾语、或定语等。 2、连接副词：when, where, why, how。有词义，在从句中担任成分，作状语。 3、连接词：that, whether, if, as if。that 无词义，在从句中不担任成分，有时可省略；if (whether), as if虽有词义，但在从句中不担任成分。 注意： 1、连接代词与连接副词在句中不再是疑问句，因而从句中谓语不用疑问式。连接代词与连接副词在从句充当句子成分，连接词whether 和if（是否），as if（好象）在从句中不充当句子成分，只起连接作用。根据句义，如果连接代词与连接副词，whether、if 和as if都用不上时，才用that作连接词（that本身无任何含义）。 2、不可省略的连词： （1）介词后的连词 （2）引导主语从句和同位语从句的连词不可省略。 That she was chosen made us very happy. We heard the news that our team had won. （二）主语从句 1、主语从句在复合句作主语。 e.g. Who will go is not important. 2、用it作形式主语，主语从句放在句末。 e.g. It doesn’t matter so much whether you will come or not. 主要句型有： （1）It+be+形容词+that从句。 It is probable that he told her everything. 很可能他把一切都告诉她了。 （2）It+be+名词词组(no wonder, an honour, a good thing, a pity, no surprise, etc.)+that从句。It’s no surprise that our team should have won the game. 我们没赢这场比赛真意外。 （3）It+be+过去分词+that从句。 It is said that Mr. Green has arrived in Beijing. 据说格林先生已经到了北京。 （4）It+seem, happen等不及物动词及短语+that从句。 It seems that Alice is not coming to the party at all. Alice似乎不来参加晚会。 （5）It+doesn’t matter (makes no difference, etc.)+连接代词或连接副词引起的主语从句。 It doesn’t matter whether she will come or not. 她是否来这无关紧要。 It makes no difference where we shall have the meeting. 我们在哪里开会毫无区别。 3、that引导主语从句时，不能省略。 e.g. That he suddenly fell ill last week made us surprised. 4、当主语从句作主语时，谓语动词一般用第三人称单数，下面这个句型例外。 What we need is more time and money. What we need are many more books. 5、if不能用在主语从句中，而是用whether Whether he left (or not) is unknown 6、引导主语从句的关联词有三类： (1)从属连词that。
名词性从句知识点梳理及经典练习(超详细) 一、名词性从句 1． ---- Let's send him home. Do you know _________? ---- I have no idea. A. where does he live B. where he lives C. he where lives D. he lives where 【答案】 B 【解析】【分析】句意:----让我们把他送回家。你知道他住在哪里吗?----我不知道。宾语从句就是一个句子作动词或介词的宾语。宾语从句由特殊疑问句变来就用原来的疑问词作引导。在宾语从句中只能使用陈述句语序，不能用疑问句语序。所以选B。 2． is clear to the members of the committee is that the President will not give in to their demands. A. Who B. It C. As D. What 【答案】 D 【解析】【分析】句意：委员会成员清楚的是，总统不会向他们的要求让步。that the President will not give in to their demands.这个句子作表语； is clear to the members of the committee这是主语从句，这里缺少主语从句的连接词，并且连接词在句中作主语，it是代词，不是了；连接词，故排除B；as作主语时，是在定语从句中，故排除C；who指人，根据表语指的事情，不是人，故排除A；what在主语从句中可以作主语或宾语，指事，符合句意，故选D。 【点评】考查名词性从句，本题涉及what引导的主语从句。 3． is even more important is the earth cooled down, water began to appear on its surface.
