2. Whether he will come to the party is still uncertain.他是否会来参加派对还不确定。

主语从句常常出现在it is/was +从句结构中,以强调句子的主语。

名词性从句专题讲解一、复习句子成分二、句子种类简单句、并列句、复合句(三大从句)一、名词性从句:在句子中起名词作用的句子叫名词性从句(Noun Clauses)。

1)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。

2)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。

主语从句What he wants to tell us is not clear.宾语从句He has told me that he will go to Shanghai tomorrow.名词性从句表语从句The fact is that we have lost the game.同位语从句I have no idea when he will come back home.1. 这里重点强调一下同位语从句,顾名思义,所谓同位语从句就是一个句子与主句中某一个名词互为同位语!那么什么是同位语呢,很简单就是相同地位,相同成分,平起平坐,A(名词)=B(从句), B(从句)=A(名词), 去掉任何一部分(A/B)对整个句子都不影响。

2. 而且与从句互为同位语的名词一般为抽象名词,例如:advice、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、truth、wish、word等。

二、引导名词性从句的连接词1.引导名词性从句的连接词可分为三类:1.连词:that(无任何词意)whether, if(均表示“是否”)as if ,as though(均表示“好像”,“似乎”)以上在从句中均不充当任何成分2. 连接代词:what, whatever, who, whoever, whom, whose, whichever, whomever3. 连接副词:when, where, how, why, how many, how much, how often2. 连接词的判定:根据连接词在从句中所做的不同的成分,我们可以归纳如下:人物主语:who what宾语:whom what名词性从句表语:whom what定语:which what whose状语:when where why how (how many, how much, how often)不做成份:that if/whether as if /as though互动精讲【知识梳理1】宾语从句(一)宾语从句简介用作宾语的从句叫做宾语从句。

一、名词性从句名词性从句在句子中扮演名词的角色,可以作为主语、宾语、表语或同位语。

常见的名词性从句有主语从句、宾语从句、表语从句和同位语从句。

1. 主语从句:从句作为整个句子的主语,通常以从属连词"that"引导。

例如:- What he said is true.(他说的是真的。

)- That he is late is unacceptable.(他迟到是不可接受的。

)2. 宾语从句:从句作为句子中的宾语,可以由多个引导词引导,如"that"、"if"、"whether"、"who"、"what"等。

例如:- I don't know if he will come.(我不知道他是否会来。

)- She asked me what my favorite color is.(她问我最喜欢的颜色是什么。

)3. 表语从句:从句作为句子中的表语,通常以从属连词"that"引导。

例如:- The fact is that he lied to us.(事实是他对我们撒了谎。

)- My dream is that I can travel around the world.(我的梦想是能环游世界。

)4. 同位语从句:从句作为另一个名词或代词的同位语,通常以从属连词"that"或连接代词/连接副词引导。

例如:- The news that she won the first prize was exciting.(她赢得一等奖的消息令人激动。

㈡名词性从句的连接词
连接词即引导名词性从句的关联词,包括 连词、连接代词、连接副词。 连词:仅起连接作用,不作句子成分。 连接代词:可作主语、宾语、表语或定语。 连接副词:只作状语。
⒈连词:引导从句但不作任何成分。 ⑴that—没有意义,引导主/宾/表/同位语从句。 ①It is said that there will be a party tonight. ②They say (that) there will be a party tonight. ③Why he failed was that he made a vital mistake. ④The key that he succeeded lied in his hard work. ⑵if—是否,引导宾语从句,主语从句。 whether—是否,引导主/宾/表/同位语从句。 ①I doubt if/whether you can pass the test. ②Whether we’ll go camping depends on the weather. ③My doubt is whether you can pass the test. ④I have no idea whether you can pass the test.
主语从句中应注意的问题 1)主语从句在句首时,必须由连接词引 导,不能省略这些连接词。 误: The college will get in more new students this year is ture. 正:That the college will get in more new students this year is ture. 2)如果主语从句放在句首,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.

(完整版)名词性从句

(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。

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.2.主语从句引导词按照在句中是否做成分主要分为三类:连词that、whether、if 连接代词、连接副词。
