名词性从句讲义

名词性从句讲解1基础知识由一个主句和一个或一个以上的从句构成的句子叫复合句。

名词性从句相当于名词,可以作主语,宾语,表语和同位语。

因此,名词性从句可分为主语从句,宾语从句,表语从句和同位语从句。

如:I believe what he said.It remains to be seen whether this plan is practical enough to keep the project going.名词性从句的基本用法名词性从句就是用三种句子(陈述句、一般疑问句以及特殊疑问句)来分别充当另一个句子的四种不同句子成分(主语、宾语、表语和同位语)。

理解这一本质,是解决名词性从句的关键。

三种句子充当名词性从句时的结构变化:①陈述句作成分时,需要在句首加that; ②一般疑问句作成分时,需要将疑问句变成陈述语序,然后在句首加上whether或if,以保留原句的意义(if只用在宾语从句中);③用特殊疑问句作成分时,只需将疑问句转换成陈述语序。

要学会分析疑问词的成分。

如:I have no idea when they will visit our school; we have got everything ready.What matters most in learning English is enough practice.Elephants have their own way to tell the shape of an object and whether it is rough or smooth.一、名词性从句的连词用法名词性从句的连接词有从属连接词、连接代词和连接副词。

考点一从属连接词1. that无词义,不做成分;that引导宾语从句时可省略,但引导的并列的宾语从句时,后一个that 不可以省略。

That an earthquake happened in Sichuan shocked all the Chinese people.He said (that) he had been working here for ten years and that he wanted to go home.2. whether/ if “是否”,不作成分,不省略。

The haven't known if/ whether they hand in their homework.注意:以下情况中用whether不用if⑴. 主语从句、表语从句、同位语从句、介词后的宾语从句中。

⑵. 与or not直接连用时。

⑶. 与不定式连用时。

He was worried about whether he passed the English exam.I don't know whether to go or not.Whether it will rain tomorrow is unknown.3. because“因为”,as if/ though“好像”,可引导表语从句,不作成分。

His success is because he works hard.【反馈练习】用正确的词填空1. It’s no surprise __________ our team has won the game.2. I don’t care __________ or not she comes.3. It looks __________ it is going to rain.4. I consider it necessary __________ he should improve his pronunciation.5. That’s __________ he didn’t work hard enough, so he fails again.考点二连接代词连接代词有特殊疑问词who, whom, whose, what, which以及疑问词-ever。

它们有词义,在句子中作主语,表语,宾语或定语。

1. who“谁”,可作主语或宾语;whom“谁”,可作宾语;whose“谁的”可作定语或表语,指人; which“哪一个”,可作主语、宾语或表语。

I wonder who/ whom he will invite to his wedding.Who let out the secret remains unknown.Whoever let out the secret will be punished.2. what在从句可作主语,宾语或表语。

what的六种常考用法如下:①……的事/物/话。

如:China is no longer what she was 30 years ago.③……的时间。

如:After what seemed like two hours, we arrived there.④……的地点。

Warm sunshine and soft sands make _____ it is.6. ______ matters most in learning English is enough practice.7.

名词性从句复习讲义 高三英语一轮复习

名词性从句复习注意:1.在名词性从句中,连接词的选择要根据从句的句意和上下文来确定。

2.当从句是陈述句时,通常使用连接词that(可省略,但在正式文体中建议保留);当从句是疑问句时,通常使用whether/if(表示选择或疑问)或连接代词/副词(表示具体的疑问内容)。

3.在宾语从句中,当从句是特殊疑问句时,其语序要调整为陈述句语序。

4.同位语从句与定语从句的区别在于:同位语从句是对前面名词或代词的具体内容的阐述或解释,而定语从句则是对前面名词或代词的修饰和限定。

一、主语从句定义:在句子中充当主语成分的从句。

引导词:that, whether, if, who, whom, which, what, whose, how, when, where等。

使用原则:主语从句通常位于句首,用于描述句子的主要动作或状态的执行者或承受者。

它可以是陈述句、疑问句或祈使句(但祈使句作为主语从句的情况较少见)。

构成:主语从句通常由连接词that(可省略,但当从句中有疑问词或表示否定、强调等意义的词时,通常不省略)或whether/if(表示选择或疑问)引导,后面跟完整的句子结构。

例句:1.What he said made me think deeply.2.Whether he will come or not is still a mystery.3.How we can solve the problem is our main concern.4.That the earth moves around the sun is a well-known fact.5.Whoever breaks the law should be punished.练习题1._____ he said at the meeting surprised us all.A.

3. 连接副词:when(=the time when什么时候,何时),where(=the place where什么地方,何地),how(=the way that/in which怎样, 以……方式,如何),why=the reason why为什么)。它们除起连 接作用,还在从句中作状语。
3) wh类连接词引导的主语从句: wh类连接词包括wh类的连接代词(who, whom,
whose, which, what, whoever, whomever, whichever, whatever等)和连接副词(when,
where, how, why, whenever, wherever, however 等)。what, when和wh-ever类的词有时可不表 疑问。wh类连接代词在句中既起连接作用, 又可充当主语、宾语、表语、定语等成分。 wh类连接副词在句中起连接作用,在从句中 可充当时间、地点、原因、方式状语。
【温馨提示】 ①whether/ if引导宾语从句表示“是否”
的意思时,一般情况下可互换。 ②if引导宾语从句时可以有否定式,而
whether从句则没有。 e.g. I don’t care if he doesn’t come.
5) 特殊疑问词引导的宾语从句: 由who, what, how, which, whose, where, why等词引导的宾语从句,可作动词、 介词及形容词的宾语。
【温馨提示】 doubt, doubtful与sure后名词性从句连接词 that, whether, if的选择。 ①当doubt, doubtful用于肯定句时,后面的名
词性从句的连接词常用whether或if;当 doubt, doubtful用于否定句或疑问句时,后 面名词性从句的连接词用that。

名词性从句讲解在复合句中起名词作用的从句叫做名词性从句。

它包括主语从句、宾语从句、表语从句和同位语从句。

名词性从句是中学阶段的一个重要语法项目,在历年的高考中几乎都涉及到,并且每年的命题各有变化。

分析历届高考试题名词性从句考查的焦点主要有以下六个方面1. 考查名词性从句的语序问题2. 考查引导词that与what的区别3. 考查it在名词性从句中作形式主语或形式宾语的用法4. 考查whether与if的区别5. 考查名词性从句中的疑问词+ever引导的名词性从句与no matter+疑问词引导的状语从句的区别6. 考查名词性从句的虚拟语气问题(一)语法要点剖析一、名词性从句主语从句、表语从句、宾语从句、同位语从句,在整个句子中所起的作用,相当于一个名词。

因此,这四种从句通称为名词性从句。

引导名词性从句的连接词可分为三类:连接词:that, whether, if (不充当从句的任何成分)连接代词:what, whatever, who, whoever, whom, whose, which.连接副词:when, where, how, why1. 主语从句作句子主语的从句叫主语从句。

主语从句通常由从属连词that,whether,if和连接代词what,who,which,whatever,whoever以及连接副词how,when,where,why等词引导。

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。

例如:What he wants to tell us is not clear. 他要跟我们说什么,还不清楚。

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。

4. 在名词性从句中一律用陈述句的语序,即使从句表达的是疑问含义。

三.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。

四.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。

That he will succeed is certain.Whether wild life can be well protected is of great importance.Who will go makes no different.Which kind of food is the best is still not certain.What is needed for the space trip is careful preparation.Whoever comes is welcome.How we can help the twins will be discussed at the meeting.When they’ll start the project has not been decided yet.Where he hid the money is to be found out.Why dinosaurs died out remains a puzzle.单个主语从句作主语时,谓语动词用单数形式。

宾语从句 相当于名词,在复合句中做主语的宾语。

He asked me whom I was waiting for. 他问我在等谁。

Could you tell me if Mr. Li lives here? 你能告诉我李先生是否住在这?同位语从句一般跟在某些抽象名词后(如news, promise, idea, suggestion, fact, problem, advice, thought, truth, belief, message, hope, order 等),用以说明其具体内容。

The news that our football team won the match was encouraging. 我们球队赢得了比赛的消息令人鼓舞。

名词性从句讲义重点与难点1.从句语序问题2. if 与whether3.名词性从句的虚拟语气4. 疑问词+ever与no matter+疑问词5. 同位语从句和定语从句的区别6. 宾语从句的时态7. 否定转移主语从句一It做形式主语的固定句型1)It is + adj. / n. +从句It is a pity/shame that...遗憾的是…It is possible that...很可能It is unlikely that...不可能……2)It +不及物动词+从句It seems/appears that...似乎……It happened that...碰巧……3)It + be +过去分词+从句It is said that...据说……It is known to all that...众所周知……It is reported that...据报道……It is believed that...据信……;人们相信……It is suggested that...有人建议……It must be pointed out that...必须指出……It has been proved that...已证明…….例如:It is suggested that the meeting should be put off.有人建议会议延期召开。

二、学习主语从句应该注意的几个问题1)引导词that与whatwhat既有引导主语从句的作用,同时又在从句中作句子成分(主语、宾语、表语等).这时what相当于all that/everything that...,常译成"所……的(东西、事情、话等.)";而that只起连接作用,本身无实际意义,在从句中也不担当任何句子成分.但that引导的主语从句放在句首时,不能省略that.例如: What is done can't be undone. (谚语)已成定局,无可挽回.What we can't get seems better than what we have.我们得不到的东西似乎比已得到的要好.That a new teacher will come to teach us geography is true.一位新老师将来教我们地理,这是真的.2)引导词if和whetherif和whether引导动词后的宾语从句时一般可通用,但1)介词后的宾语从句、2)主语从句(放在句首时)、3)表语从句.4)动词不定式,5)or not 6)宾语从句时否定句时常与whether连用。
