名词性从句讲义

名词性从句讲义一.名词性从句:意思,选that.。

二. 连接词1. 指人:who (主,宾), whom(宾), whose(定), whoever, whomever,2. 指物:what (主,宾) which (宾) whatever(主,宾) whichever (宾)3. 两无:that (无成分,无意思)4. 指时间:when,(状语),whenever5. 指地点:where (状语)wherever6. 指方式,程度:how (状语)however7. 指原因: why (状语)8. 指“是否”:whether if (无成分)注意:(1).what 和which 的区别:what 是泛指,较笼统事物;而which是特指,特定范围内的“哪一个”Eg. What do you like? Which do you like?(2) what和how的区别:what表示人或事的特征和本质;how表示人或事的外在的样子。

What is it?How is it?She has what it takes to be a doctor. (必要条件)That is what is called a new fashion (所谓的)(3). that 只有在宾语从句中可以省略(4). whether 和if 都可以引出名词性从句,在宾语从句中,可以互换。

但是在其它名词性从句中,只能用whether. 即:if只能引导宾语从句,而whether可以引导所有名词性从句。

I don’t care if or not he has realized his mistake.(×)I don’t care whether or not he has realized his mistake.(∨)I don’t care if he has realized his mistake or not. (∨)三.主语从句典型句式:1、It + be + 形容词+ that从句:It is clear that he was telling the truth.It’s probable that we’ll be a little late.2、It + be + 名词词组+ that从句:It’s a pity that you can’t go with us.3、It + 及物动词+ 宾语+ that从句:It worried her a bit that her hair was turning grey.It shocked me that Peter didn’t tell anybody where he was.4、It + be + 过去分词+ that从句:It is said that he has been there many times.5、It + seem/happen/appear等不及物动词+ that从句:It seems that he has lost something.Eg.1.That you can’t match him at chess is not true, is it?2.Whether we’ll go outing depends on the weather.3.It is no wonder that he hasn’t passed the exam.4.It is certain/likely/possible that he will pass the exam.5.It hasn’t been decided whether the meeting will be held tomorrow.6.It is said/reported/well known/believed that he has passed the exam.7.It happened that I didn’t take any money with me.8.It never occurred to him that he would get into trouble.9.It doesn’t matter whether he is wrong or not.10.It is important/necessary that he (should) learn English well.四.表语从句典型句式:1.The reason for his absence was that he was ill in hospital.2.The reason why he was absent from school was that he was ill in hospital.3.The question is whether they will be able to help us out4.All this was over 20 years ago, but it’s as if it were only yesterday.五.宾语从句典型句式:1.I wonder if /whether it is true or not.2. He is worried about whether she has passed the exam.3. Give a reading list to whoever comes. 给所有来的人以份阅读书目4. He’s confident (that) he will win.5. He made it quite clear that he preferred coffee to tea.6. I think it best that you should seek for a new solution to the problem7. He only wished (that) he could look at hes daughter, and that she would look at him.两个及以上表示陈述的宾语从句并列时,第一个连词that可以省略,但第二个及以后的不可省。

又如:He told me (that)they could not decide what to do and that they asked my advice..8. Please let me know if you need my help.Please let me know if you need my help.重点:1.在含有“建议,要求,劝告和命令”的名词性从句中,谓语需要用(should)+动词原形。

表“建议,要求,劝告和命令”的动词和名词有:suggest,suggestion; advise,advice;demand; require, requirement;request; insist;command;order;Eg. I suggest (that) he (should) be sent to work there. (宾语从句)I gave a suggestion that he (should) be sent to work there.. (同位语从句)2. it作形式宾语,从句作真正宾语。

(1)动词+ it + important / necessary / natural / etc. + that-clause。

That-clause 中谓语动词前可加should,亦可省略。

如:I think it important that you (should)attend the conference.(2)动词+ it + as + 名词/ 形容词+ clause。

如:The lecturer takes it as encouraging when so many students attend his lecture.(3)动词+ it + 介词+ that-clause。

常见的有:owe it to sb. + that-clause(把……归功于某人),leave it to sb. + that-clause(把……留给某人去做),take it forgranted+ that-clause (想当然),keep it in mind + that-clause (记住……)。

如:I just took it for granted that he’d always be around.(4)动词+ it + clause。

如:I hate it when people talk with their mouths full.英语中少数介词很活跃,能带从句作其宾语。

如:I go to see a film except whenit rains.3. 含宾语从句的反意疑问句。

当陈述部分带有that引导的宾语从句时,疑问部分的主语和谓语一般应与陈述部分主句的主语和谓语保持对应关系。

如:Brian told you that there wasn’t anyone in the room at that time,didn’t he?当陈述部分主句的主语是第一人称,谓语动词是think / believe / suppose /guess / imagine / expect / suspect / feel等时,疑问部分的主语和谓语往往与陈述部分从句中的主语和谓语保持对应关系,此时实质上是将对主句的否定转移到对从句的否定上。

如:I don’t suppose anyone will volunteer, will they?4. 宾语从句的时态要和主句相呼应:⑴. 如果主句谓语动词是现在时或将来时,从句谓语动词时态可不受约束;⑵. 如果主句谓语动词是过去时,从句谓语动词的时态须与之呼应,用过去范围的时态;Eg. I thought he had gone to town today.⑶当从句叙述的是客观真理时,其谓语动词仍用现在时态。

如:Eg. Galileo insisted that the earth moves round the sun.5.名词性从句在句中要用陈述句语序。

如:He asked me what was the matter with me.We’ve heard the news that we’ll move intothe new house.Whatever you say will interest us all.6.两个及以上表示陈述的宾语从句并列时,第一个连词that可以省略,但第二个及以后的不可省。

高中名词性从句讲义

高中名词性从句讲义

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1.连接词that;不充当句子成分; 无词义; 只起连接作用。

2. if/whether;意为“是否”,有词义2; 不做句子成分; 起连接作用3.连接代词:what(ever), which(ever), who(ever), whom(ever), whose(ver)有词义; 引起从句; 且在从句中充当一定的句子成分,常做从句中的主语、宾语、表语和定语。

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。

I don’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。

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。
