6名词性从句
名词性从句知识点
复合句中具有名词性质并且可以做主语、表语、同位语或宾语的从句叫名词性从句。
因此，我们把主语从句、表语从句、同位语从句和宾语从句这四种从句统称为名词性从句。
高考热点1）怎样判断名词性从句的类别；2）连词that 和what的用法与选择3）if 与whether的区别4）同位语从句与定语从句的区别5）名词性从句必须采用的陈述语序6）it 可充当形式主语和形式宾语7）疑问词+-ever的连词和不加-ever的连词在语义上的用法和差别核心解读一1、在名词性从句中，从句都用陈述语序。
2、引导名词性从句的词叫引导词。
引导词可以分为以下几类：1）从属连词that（用于表示肯定的含义）, whether, if (表示疑问)，这三个词只起连接作用，不充当从句中的任何成分，除宾语从句外（that可省）,这些词均不可省略。
2）连接代词有who, whom, whose, what, which, whoever, whatever, whichever等。
这些词在从句中既起连接作用，又充当从句中的成分，如主语、宾语、表语、补语，且不可省略。
3）连接副词有when, where, why, how, wherever, however等。
它们既起连词作用，本身又做从句中的状语。
3、名词性从句中的时态一致问题1）在宾语从句中，当主句是一般现在时、将来时或现在完成时，起从句的谓语根据需要用适当的时态。
当主句是一般过去时，从句用过去的某个时态，但若宾语从句表示客观真理，格言，谚语等，从句的时态仍用一般现在时。
Have you told him that when we are to leave?Teacher told us that China lies in the west of Japan.Although she was listening, she didn’t hear what he was saying because t here was so much noise.2）在主语从句、表语从句或同位语从句中，应注意主语从句中的谓语动词的时态一致性及动作发生的先后关系。
名词性从句翻译
名词性从句翻译名词性从句是一种从句，用作名词的作用，可以在句子中担任主语、宾语、表语、同位语或介词宾语。
名词性从句一般由连接词引导，包括连词that, whether/if , 连接代词who, whom, what, which, whoever,whomever, whatever, whichever, 连接副词when, where, why, how等等。
名词性从句的翻译要根据具体的上下文和句子结构进行灵活变通。
下面是一些常见的名词性从句的翻译示例：1. 主语从句：That he is late again is not surprising.他又迟到了并不奇怪。
2. 宾语从句：I don't know where she went.我不知道她去哪里了。
3. 表语从句：The problem is whether we can solve it.问题是我们是否能够解决它。
4. 同位语从句：The news that he passed the exam made us happy.他通过考试的消息使我们很高兴。
5. 介词宾语从句：I am not sure about what he said.我不确定他说的是什么。
6. 间接引导名词性从句：He asked where I lived.他问我住在哪里。
7. 是否从句：I wonder whether/if she will come to the party.我想知道她是否会来参加派对。
8. 选择性从句：He asked me whether I preferred coffee or tea.他问我是喜欢咖啡还是茶。
9. 宾语从句（陈述句变为疑问句）：Do you know what time it is?你知道现在几点钟吗？10. 宾语从句（连接代词）：I wonder who is going to pick us up at the airport.我想知道谁会在机场接我们。
名词性从句解析及常用例句
名词性从句Noun Clauses在句子中起名词作用的句子叫名词性从句(Noun Clauses）。
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、介词宾语等，因此根据它在句中不同的语法功能，名词性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。
一、主语从句作句子主语的从句叫主语从句。
主语从句通常由下列词引导：1）从属连词that，whether 等；2）连接代词what，who，which，whatever，whoever，whom 等；3) 连接副词how，when，where，why 等。
that在句中无词义，只起连接作用；连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用，在从句中充当从句的成分。
注：whom、who指人，what指物，whatever，whoever表示泛指意义。
例如：That I am beautiful is known to everyone. 众所周知，我是个万人迷。
What he wants to tell us is not clear. 他要跟我们说什么，还不清楚。
Who will win the match is still unknown. 谁能赢得这场比赛还不得而知。
It is known to us how he became a writer. 我们都知道他是如何成为一名作家的。
Where the English evening will be held has not yet been announced. 英语晚会将在哪里举行，还没有宣布。
有时为避免句子头重脚轻，常用形式主语it代替主语从句作形式主语放于句首，而把主语从句置于句末。
主语从句后的谓语动词一般用单数形式。
常用句型如下：（1）It + be + 名词+ that从句（2）It + be + 形容词+ that从句（3）It + be + 动词的过去分词+ that从句另注意在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时，谓语动词要用虚拟语气“(should) +do”，常用的句型有：It is necessary (important, natural, strange, etc.) that …It is suggested (requested, proposed, desired, etc.) that…二、宾语从句名词性从句用作宾语的从句叫宾语从句。

英语语法讲解课件第6讲名词性从句
The subjunctive mood is a grammatical construction used in noun clauses to express wishes, hypotheses, or conditions contrary to fact.
It is important to note that the subjunctive mood is typically indicated by the use of "were" instead of "was" in the subject of the clause, as well as the use of "had" instead of "had been" in the past perfect tense.
03
It is essential to understand that the role of "it" as the formal subject of a noun clause is to provide clarity and structure to the sentence, ensuring that the meaning is conveyed effectively.
The which clause can be omitted in some cases, especially when it is clear from the context who or what is being referred to.
The which clause can be used at the beginning or end of a sentence, depending on the context and the emphasis required.

(完整版)名词性从句
名词性从句一．概述：在句子中起名词作用的各种从句统称为名词性从句。
根据它们在句中的语法作用，这类从句又可分为主语从句、表语从句、宾语从句和同位语从句。
二．名词性从句连接词四．if, whether的区别1.引导主语从句时，如果主语从句放在句首，只能用whether不能用if引导，但是如果用it 做形式主语，而把主语从句放在句末时，也可以用if引导.2.引导宾语从句时常放在动词know, ask, care, wonder之后，if和whether均可。
少数动词，如: leave, put, discuss, doubt后的宾语从句常用whether. 。
3.在介词后面的宾语从句中，在表语从句、同位语从句中，表“是否”，只能用whether；4.whether和if都可以和or not连用,但是whether 之后可以直接跟or not,而if不可以。
I do n’t know whether or not I will stay.（只能用whether）5.在不定式前只能用whether.如：I can’t decide whether to stay. 我不能决定是否留下。
五．与“命令、要求、建议”等相关的名词性从句中通常用虚拟语气，虚拟语气的构成是“should＋动词原形”或省去should，直接用动词原形。
六．名词性从句以考查引导词为主，同时考查时态，语序，与其它从句的区别以及混同虚拟语气的考查。
一．主语从句1.主语从句定义：在复合句中充当主语的句子叫做主语从句。

名词性从句—表语从句(Predictive Clause)
• 表语从句:在句中充当表语成分，一般放在 连系动词之后。 • 作用：对主语进行解释说明。
• 表语从句通常由that和what引导， 但有时也可由how，what，when， where，why等来引
The question is whether we can rely on him. He looked as if he was going to cry. That’s why I was late.
连接副 when，where， how，why等。 词
连接并替代状语
名词性从句——主语从句(Subject Clause)
• 用作主语的从句叫做主语从句(Subject Clause)。引导主语从句的连接词： 1. 连词： whether, that 2. 连接代词：who, whom, whose, what, which, etc. 3. 连接副词：when, where, why, how, etc.
6. 宾语从句的替代
• 在hope believe, imagine, suppose, guess, think等动词以及I’m afraid 等表达法的后面， 可用so代替一个宾语从句，该宾语从句通常 是上文提到的一件事。例如： • -- Do you think we will have good weather? • -- I hope so.
4. We all know the truth ____ the earth ____ around the sun. A. if; moved B. that; moves
C. why; move
D. whether; move 同位语从句
Can you distinguish THAT-CLAUSE in the two sentences?
3. 宾语从句的时态呼应
• 如果主句的谓语是过去时，宾语从句时态 要按照时态一致原则进行相应的调整。但 是若宾语从句表示的是客观真理或自然现 象，其谓语时态仍用一般现在时。 • He said that he had left the umbrella in the library. • The teacher told the students that the Pacific Ocean is the largest ocean in the world.
5. 插入语
• 在think，believe，suppose，expect，imagine， say等动词所跟的宾语从句中，如果要对宾语从句 中的相关信息进行提问，通常要用到“插入语疑 问句”。该结构以所询问信息有关的疑问词开头， 主句的主谓成分变成插入语，而宾语从句仍然使 用陈述语序。如： • I think that John will arrive at five o’clock. （提问 at five o’clock） • When do you think John will arrive?（此处的do you think变成了插入语）
1. Whether和if都可以引导宾语从句
当whether后紧跟or/or not时,不用if.
I don’t know whether I will stay or not
介词后面的宾语从句不能用if. I worry about whether I hurt her feeling.
在主+谓+it (形式宾语) +宾补+that 从句(真正宾语) 的句型中不省略 We must make it clear that we mean what we say. 由连词and连接的两个由that引导 的宾语从句中,第二个that 不省略。 He told me (that) he would come and that he would come on time.
2. I wonder ____ you will go shopping or stay at home. 宾语从句 A. that B. if C. whether D. what
3. This is _____ he was often late for school. 表语从句 A. what B. that C. why D. whether
{What he does is importan day.
This is his job.
His job is important.
{I don’t like what he does every day. {
I don’t know about the man, Mr. White. I don’t know about the fact that he is a teacher.
4. 宾语从句否定意义的转移
• 在think, believe, suppose, expect 等词所跟 的宾语中，如果从句谓语是否定的，一般 要将否定词not转移至主句谓语上去，而降 从句宾语 变成肯定形式。 • I don’t think he has time to play chess with you. • 我想他没有时间和你下棋。 • I don’t suppose it is the rush hour yet. • 我估计现在还未到交通高峰时间。
形式主语
“It” is used as empty subject 为避免主语冗长,句子头重脚轻,经常 用it作形式主语,主语从句放在后面作 真正的主语。 1. It is certain that he will succeed. 2. It is not known whether he will go there. 3. It has not been decided yet when they’ll start the project.
• 例：--I haven’t heard from Henry for a long time. • --What do you think ________ to him? • A. is happening B. was happening • C. to happen D. happens • 【答案】B。do you think为插入语，插入 特殊疑问句时，疑问句用陈述结构，故 what为主语，happen形式为谓语，因此B 为正确答案。
