名词性从句讲解与辨析

英语语法:名词性从句语法讲解 时间:2016-10-08作者:来源:精品学习网 笔者在此就名词性从句中的几大易错点进行分析,希望对同学们有所帮助。 [关系代词和关系副词的误用] 例1 (2016·全国卷Ⅰ) My uncle is the owner of a restaurant close to that I live. 解析 that→where。本题考查宾语从句,引导词在从句中充当地点状语,所以将that改为where。 例2 (2015·全国卷Ⅱ) As natural architects, the Pueblo Indians figured out exactly thick the adobe walls needed to be to make the cycle work on most days. 解析 how。根据语境和空后的形容词thick可知应用how引导宾语从句,此处表示要弄清楚到底土坯房的墙需要“多”厚。故答案为how。 点拨若从句缺少主语、宾语、表语或定语,则考虑用关系代词;若从句缺少时间、地点、原因、方式等状语成分,则使用关系副词 (when/where/why/how)。 [if和whether的误用] 例3 He asked her the question if they can be friends. 解析 if→whether。question后为同位语从句,只能用whether来引导,故而将if改为whether。 例4 It doesn’t matter so much you will come or not. 解析考查主语从句。句意:你来还是不来,这不怎么重要。代词it作形式主语,真正的主语是whether引导的主语从句。 点拨在表达“是否”这一意思时,我们经常会用到whether和if,但以下几种情况只用whether不用if: 1. 在表语从句、主语从句、同位语从句中; 2. 在介词后的宾语从句中。如:It all depends on whether they will

2011届高考英语一轮复习讲解:it的用法

2011届高考英语一轮复习讲解:it的用法【知识要点】 It的用法 (一)作人称代词 1、it代替前面(或后面)的单数名词或分句等所表示的事物。 e.g. You cannot eat your cake but have it.(it代替前面的cake) Although we cannot see it, there is air all around us. (it代替后面的air) They say he has left town, but I don’t believe it.(it代替前面They…town分句中的情况) 2、代替有生命但不能或不必分阴阳性的东西(包括婴儿)。 e.g. Yesterday we saw a big tree. It was fully twenty metres high. (it代替前面的tree) The baby cried because it was hungry. (it代替前面的baby) 3、在某些习惯说法中,可以代替人。 e.g. ---- Someone is knocking at the door, Peter. ---- Who is it? ---- It’s me. ---- Who are singing? ---- It is the children. ---- The light is still on in the lab. It must be the third-year students doing the experiment. 4、it与one的区别:这两个词都可以代表前面说过的名词,但it用于同名同物的场合;one则用于同名异物的场合。 e.g. ---- Do you still have the bicycle? ---- No, I have sold it. ---- Is this knife yours? ---- No. It is Xiao Zhang’s. Mine is the one on the desk. 5、it与that的区别:两词都可代替某一特定名词,但that指同一类,并非同一个。 e.g. The climate of South China is mild(温和的); I like it very much.(it指the climate of South China) The climate of South China is much better than that of Japan.(that指the climate)(二)作无人称代词 it作无人称代词时,除了句中找不到它所代表的词语外,另一个特点是它后面的内容都是表示天气、时间、距离、度量衡及情况等。 It is fine (rainy, windy, etc.). It is noon. It is a half hour’s walk to the f actory. It is eighteen square metres in area. What does it matter? (三)作强调词,构成强调结构

【英语】英语名词性从句解题技巧讲解及练习题(含答案) 一、初中英语名词性从句 1._______ makes me feel worried is _______ singing stars are centered on by masses of teenagers today. A. What; what B. That; that C. What; that D. That; what 【答案】 C 【解析】【分析】句意:让我感到担忧的是,今天的歌星是以青少年为中心的。分析句子可知,主语从句中的谓语动词makes 缺少主语,主语从句中缺少宾语一般用what,因此选择 what 来引导主语从句;系动词 is 后面的表语从句句意完整,不缺少成分,因此选择 that 引导表语从句。分析选项可知C项符合题意,故选C。 【点评】考查名词性从句,本题涉及what引导的主语从句和that引导的表语从句的应用。 2.________ is known to us all that the old scientist, for ________ life was hard in the past, still works hard in his eighties. A. As; whose B. It; whose C. As; whom D. It; whom 【答案】 D 【解析】【分析】句意:我们都知道,那位老科学家,过去生活很艰苦,到了八十多岁还在努力工作。第一空it is known to us all that…是个固定句型,意为“众所周知…”;第二空为介词+关系代词引导的定语从句,先行词the old scientist指人,作介词for的宾语,只能用whom,故选D。 【点评】考查名词性从句和定语从句,本题涉及固定句式it is known to us all that…和whom引导的限制性定语从句。 3.Some people believe _______ has happened before or is happening now will repeat itself in the future. A. whatever B. whenever C. wherever D. no matter what 【答案】 A 【解析】【分析】句意:一些人认为之前发生的或现在正在发生的任何事情在将来都会重复发生。Whatever has happened before or is happening now是一个主语从句,whatever既引导起这个主语从句,也在句中做主语。BC项都属于副词的性质,都不能做主语,通常只能做状语;no matter what只能用来引导状语从句,故选A。 【点评】考查名词性从句,本题涉及"特殊疑问词+ever"引导的主语从句。 4. is even more important is the earth cooled down, water began to appear on its surface.

初中语法祈使句专项讲解

初中语法祈使句专项讲解 1、祈使句的概念表示请求、命令、建议、祝愿、邀请或要求的句子叫祈使句。用于祈使句句首的动词总是用原形,不能用其他形式。如:Shut the door! 把门关上!Have a cup of coffee! 喝杯咖啡吧!Let them go by train、叫他们坐火车去吧。祈使句的主语通常为第二人称(you),但一般都被省略,只有在特殊的情况下才把主语(you)补充出来。如:You be quiet! 你安静! You go and tell him, Chris、克立斯,你去告诉他。You wait here for a moment、你在这儿等一会儿。有时祈使句的主语也可以是everybody, somebody, anybody, nobody等不定代词。如:Stand up, everybody! 全体起立!Nobody move、任何人都不许动。 2、祈使句表示强调为了加强祈使句的语气,我们通常是在祈使句的动词原形前加上助动词do,此时通常译为“一定”“务必”等。如:Do be careful、务必要小心。Do let me go、一定让我去。副词never和always有时可用于祈使句句首,表示强调。如:Never do that again、再不要这样做了。Always look in the mirror before starting to drive、一定要先看看反光镜再开车。 3、祈使句的否定式构成祈使句否定式的方法很简单,那就是在动词原形前加don’t不管祈使句所用的动词为什么性质动

词,情况都是一样。如:Open the window、把窗户打开。 →Don’t open the window、别把窗户打开。Come next Monday、下周星期一来。对于以let us或let’s开头的祈使句,其否定式通常是在不定式之前放一个not。如:Let’s tell him the truth、我们把实情告诉他吧。→Let’s not tell him the truth、我们不要把实情告诉他。但在日常口语中,我们也可以把don’t放在let’s之前。如:Let’s don’t tell him the truth、我们不要把实情告诉他) 4、祈使句与连用please为了使祈使句的语气变得委婉,我们可以在祈使句的句首或句末加上please若加在句首,其后不用逗号;若加在句末,则通常会在please前加一个逗号。如:Step this way, please、请这边走。Please type your letter、请把你的信打出来。Open the window, please、请把窗户打开。如果是否定祈使句,则通常将please加在don’t之前。如:Please don’t get angry、请不要生气。Please don’t telephone before8 a、 m、早8点以前请不要打电话。 5、祈使句的时间概念祈使句所表示的时间总是指将来,所以与它连用的句子原则上要用将来时态来与它呼应。如:Give me a hand, will you? 帮我一个忙,好吗?由于give me a hand表示隐含将来意义,所以句中的will you 不能改为do you。Try again and you will succeed、你再试就会成功。由于句中的 try again隐含将来意义,所以句中用了you will succeed,而

it的用法归纳

?Never be afraid of grammar ?Collect some examples; ?Watch them very carefully; ?Find out something in common; ?Try to use the rules ---- practise. it用法完全归纳 一、it 作人称代词的用法 1.指事物 作为人称代词,it 可以除人以外的一切事物或动物。如: I dropped my watch and it broke. 我把手表掉在地上摔坏了。 It’s hard work, but I enjoy it. 工作很辛苦,可是我乐意干。 “Where is the dog?”“It’s in the bedroom. ”“狗在哪?”“在卧室里”。 2.指人 it 指人主要用于指不性别不明的婴儿或用于确认某人的身份。如: Is it a boy or a girl? 是男孩还是女孩? There is a knock on the door. It must be the postman. 有人在敲门,一定是邮递员。 【说明】在答语中,常用来指本人,如说It’s me。

3.代替某些代词 代词it 还可用于代替指示代词this, that 以及复合不定代词something, anything, nothing等。如: “What’s this?”“It’s a new machine. ”“这是什么?”“是一种新机器”。 Nothing is wrong, is it? 没出什么问题,是吗? 二、it 作非人称代词的用法 1.基本用法 it 作非人称代词的用法,主要用于指时间、距离、价值、天气、气候及温度等自然现象。如: It’s too late to go there now. 现在去那儿已经太迟了。 It rained all day yesterday. 昨天下了一天的雨。 It can get very hot here. 这里有时会很热。 2.用于某些句型 It’s time for sth. 该做某事了。 It’s time to do sth. 该做某事的时候了。 It’s time for sb to do sth. 某人该干某事了。 It’s (about / high) time + that-从句. 某人该做某事了。(从句谓语用过去式,有时也用“should+动词原形”) It’s first (second) time + that-从句. 某人第几次干某事。(从句谓语用现在完成时)

中考—名词性从句 主语从句 主语从句的语序 主语从句要求使用陈述句语序,而非一般疑问句语序。如: What surprised me most was that the little girl could play the violin so well. 使我感到惊讶的是这个小女孩的小提琴拉得太好了。 连接词的选用 (1)that和what的选用 that和what都可引导主语从句。what除起连接作用外,还在名词性从句中充当某些成分,可作从句的主语、宾语或表语。而that在名词性从句中不充当任何成分,无词义,只起连接词作用。如: What he wants is a book. 他想要的是一本书。 That light travels in straight lines is known to all. 众所周知,光线沿直线运行。(2)if和whether的选用 引导主语从句,不能用if,只能用whether。如: Whether we will hold a party in the open air tomorrow depends on the weather. 我们明天是否在户外开晚会要看天气而定。 (3)其它连接代词和副词的选用 根据主语从句的具体意义,正确的选择who, which, when, where, why, how等连接词,这些连接词既有疑问含义,又起连接作用,同时在从句中充当各种成分。如: When we shall hold our sports meet is not decided. 我们何时举行运动会还没有决定。 Who broke the glass yesterday is not clear. 还不清楚昨天谁打破了玻璃。 Which car you will choose to buy makes no difference. 你决定买哪一辆车都不会有任何区别。 (4)whatever / whoever的功用 whatever, whoever在主语从句中不含疑问意义。它引导主语从句,并在从句中作主语、宾语、表语等。whatever = anything that; whoever = anyone who。要注意和whatever, whoever引导的让步状语从句的区别。如: Whoever breaks the law should be punished. (主语从句)(=Anyone who breaks the law should be punished. ) Whoever breaks the law, he should be punished. (让步状语从句)(=No matter who breaks the law, he should be punished. ) it构成的主语从句 (1)由连词that引导的主语从句,在大多数情况下会放到句子的后面,而用代词it作形式主语。谓语是seem, appear, be certain, be a pity, be a wonder, be one's hope, be likely等词或短语时。 It is well-known that the earth moves around the sun. 众所周知,地球围绕太阳转。 需要注意的是,it作形式主语代替主语从句时,要注意和as引导的定语从句的区别。试比较:

名词性从句 名词性从句是由if, whether, that 和各种疑问词充当连接词所引导的从句,其功同名词一样。 一.主语从句 主语从句是在复合句中充当主语的从句,通常放在主句谓语动词之前或由形式主语it代替,而本身放在句子末尾。 1. It 作形式主语和it引导强调句的比较 It 作形式主语代替主语从句,主要是为了平衡句子结构,主语从句的连接词没有变化。而it引导的强调句则是对句子某一部分进行强调,无论强调的是什么成分,都可用连词that。被强调部分指人是也可用who/whom。例如:

It is a pity that you didn't go to see the film. It doesn't interest me whether you succeed or not. It is in the morning that the murder took place. It is John that broke the window. 2. 用it 作形式主语的结构 (1) It is +名词+从句 It is a fact that … 事实是… It is an honor that …非常荣幸 It is common knowledge that …是常识 (2) it is +形容词+从句 It is natural that… 很自然… It is strange that… 奇怪的是… (3) it is +不及物动词+从句

(right) That President Jiang will visit our school next week is said. (wrong)

(完整版)名词性从句讲解及专项练习习题及其解答

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 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, why 1. 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。 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(4)It + 不及物动词+ 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 a pity (a shame, no wonder, etc.) that… It is suggested (requested, proposed, desired, etc.) that… 2. 宾语从句 名词句用作宾语的从句叫宾语从句。引导宾语从句的关联词与引导主语从句表语从句的关联词大致一样,在句中可以作谓语动词或介词及非谓语动词的宾语。 1. 由连接词that引导的宾语从句 由连接词that引导宾语从句时,that在句中不担任任何成分,在口语或非正式的文体中常被省去,但如从句是并列句时,第二个分句前的that不可省。例如: He has told me that he will go to Shanghai tomorrow. 他已经告诉我他明天要去上海。 We must never think (that) we are good in everything while others are good in nothing. 我们决不能认为自己什么都好,别人什么都不好。 注意:在demand、order、suggest、decide、insist, desire, demand, request, command等表示要求、命令、建议、决定等意义的动词后,宾语从句常用“(should)+ 动词原形”。例如: I insist that she (should) do her work alone. 我坚持要她自己工作。 The commander ordered that troops (should) set off at once. 司令员命令部队马上出发。 2. 用who,whom, which, whose, what, when, where, why, how, whoever, whatever, whichever等关联词引导的宾语从句相当于特殊疑问句,应注意句子语序要用陈述语序。 例如:I want to know what he has told you. 我想知道他告诉了你什么。 She always thinks of how she can work well. 她总是在想怎样能把工作做好。
