高考英语二轮复习备考专项冲刺专题13名词性从句(含解析)

高考英语二轮复习备考专项冲刺专题13名词性从句(含解析)

专题13 【名词性从句】解题指导·触类旁通寻方法,求策略,掌握“套路”第一步:识别名词性从句的种类1.首先确定主句的谓语动词,确定主句的主谓结构;2.分析从句在主句中所充当的成分,确定从句所属类型:主语从句、宾语从句、表语从句、同位语从句。

第二步:分析从句结构,确定从句引导词确定从句的结构和意义是否完整,结合句意填写适当的连接词。

1.若从句结构完整,用从属连词:陈述事实用that;表示疑问“是否”用if或whether;2.若从句缺少主语、宾语、表语或定语,则考虑用连接代词;3.若从句缺少状语,则用连接副词。

另外,还需注意一些特殊的引导词(if, whether, because, as if等)的用法及that引导同位语从句与定语从句的区别。

技巧1 分析句子成分①缺少主语、宾语、表语:用连接代词what、 who、 whom、 which、 whatever等。

②缺少状语(结合句意判断):用连接副词where(表地点)、 when(表时间)、 how(表方式)、why(表原因)等。

③不缺成分,句意不完整,缺少“是否”:用if/whether。

④不缺成分且句子意义完整:用that。

技巧2 结合句意和引导词的本义解题有些引导词在句中有很鲜明的意义,如if“是否”;whoever “无论谁”;whatever “无论什么”;whichever “无论哪一个(在范围中选择)”;because“因为”;why “为什么”等。

结合句意和语境,不难解决这类试题。

①that没有词义,也不作任何成分,当从句意义完整,不缺任何成分时用that。

②what在从句中表示“……的(东西)”,在从句中充当主语、宾语、表语、定语等成分。

考点突破·针对提能明考点,攻重难,有效提升考点一、主语从句1.主语从句的引导词引导词作用that, whether, if 只起连接作用,不在从句中作成分,但一般不可省略。

高考英语二轮复习整理---名词性从句讲解

高考英语二轮复习整理---名词性从句讲解

名词性从句在英语中,句子可分为简单句和复合句,复合句即常说的“从句”。

由一个主句和一个(或几个)从句构成的句子叫主从复合句。

在复合句中,我们是根据从句在整个句子中所充当的成分来给复合句命名的。

如:主语从句,宾语从句,定语从句,等等。

所有的复合句中,“主语从句,宾语从句,表语从句,同位语从句”,他们的从句有名词性特征,因此合称为“名词性从句”。

名词性从句的引导词引导词是否在名词性从句中充当成分的情况充当成分:连接代词: what, which, who, whom, whose,whatever, whoever, whichever,不从当成分:连接副词: when, where, why, how, however只起连接的作用:that, if/whether, because(that引导的名词性从句,既不作任何成分,也无意义,只是表明从句是一种陈述语气,起个连接作用;if不能引导表语从句和同位语从句,if引导主语从句时不能置于句首,if引导宾语从句时,只能置于及物动词后,不能置于介词后;because只能引导表语从句)㈠主语从句(用作主语的从句叫做主语从句)1.that从句作主语That引导的主语从句可位于句首直接作主语;也可以位于句末,用it作形式主语;① That we are invited to a concert this evening is a piece of good news for us.②It is obvious that the earth is round.2.whether/if(是否)从句作主语同样可放句首或句末,但放句首只能用whether,不能用if.①Whether we shall go or stay ,is uncertain.②It was not known whether/if he would ask.3. whoever, whichever, whatever, however引导主语从句只能放句首。

2.(2017•天津高考改编)She asked me________ I had returned the books to the library, and I admitted that I hadn't.解析:whether/if句意:她问我是否已经把书还给图书馆了,我承认说我还没有还。

分析句子结构可知,空格处引导宾语从句,且在从句中不作任何成分,只起连接作用;又根据句意可知此处表示“是否”,故用whether或if引导宾语从句。

3.(2016•北京高考改编)The most pleasant thing of the rainy season is________ one can be entirely free from dust.解析:that句意:雨季最令人高兴的事情就是人们可以完全远离灰尘。

分析句子结构可知,本句包含一个表语从句,且表语从句中句子结构完整,故使用that引导表语从句,that在表语从句中不作句子成分,只起连接作用。

4.(2016•天津高考改编)The manager put forward a suggestion ________ we should have an assistant. There is too much work to do.解析:that句意:经理提出了一个建议,我们应该有一个助手。

工作太多了。

分析句子结构可知,空处引导同位语从句,解释说明suggestion的具体内容,故填that。

2020年高考英语二轮复习考点学与练专题09名词性从句(讲)(含解析)

专题9 名词性从句名词性从句包括主语从句、宾语从句、同位语从句和表语从句。

考查的要点主要是连接代词和副词的正确使用,主语、谓语的语序,双重连接词以及特殊句型的使用等。

其考点主要包括:1.考查名词性从句的连接词。

如:有词义的连接代词who, whose, whom, what, which; 连接副词when, where, why, how; 从属连词that, whether, if, as if; 无词义的that在从句中不担任成分,有时可省略。

2.考查名词性从句的语序和时态。

3.考查it作形式主语、形式宾语的情况。

如:(1)It+be+形容词(necessary, important, obvious等)+that从句.(2)It+be+过去分词+that从句.(3)It+be+名词(a surprise, a fact, a shame, an honour等)+that从句.(4)It+不及物动词(appear, happen等)+that从句.4.名词性从句中的虚拟语气。

如:(1)It is (was)+essential (important, natural…)+that…;等。

(2)It is (was) suggested (demanded, wished, desired…)that…5.what引导名词性从句时的语义功能和语法功能。

如:what=the thing that/anything that…;what=the等。

place that…;what=the time th at…;what=the person that…6.whoever,whatever,whichever引导名词性从句时的语义功能和语法功能。

一、几种易混的从句的辨别定语从句、名词性从句和状语从句有时候在形式上很相似,下面提供一些区分的方法:1.定语从句与同位语从句定语从句与前面的名词是修饰与被修饰的关系;而同位语从句是用来说明前面名词的内容的。

故填what。

2.This is her confusion ________ she should stick to her own way of life or follow the American way.【答案】whether【详解】考查名词性从句。

句意:这是她的困惑,她应该坚持自己的生活方式还是遵循美国的生活方式。

故填whether。

3.There is little doubt in your mind ________ he is innocent, is there?【答案】that【详解】考查同位语从句。

句意:你认为他是无辜的,对吗? 分析句子结构可知,此处考查了同位语从句;从句是对doubt的解释说明,不缺任何成分及意思,所以用连接词that。

故填that。

4.We haven't yet settled the question ________ we are going to spend our summer vacation this year.【答案】where【详解】考查同位语从句。

句意:我们还没有解决今年要在哪里度暑假的问题。

分析句子可知空格后的句子的作用是在解释说明名词“question”充当同位语的作用;又因为从句中缺少地点状语,故填where。

2020届二轮复习名词性从句【考情分析】1.what,that引导名词性从句的区别;2.whether,if引导名词性从句的区别;3.名词性从句与定语从句、状语从句的区别;4.it作形式主语、形式宾语的情况;5.名词性从句中的虚拟语气。

【知识归纳】考点一:名词性从句分类名词性从句相当于名词,可分别作主句的主语、表语、宾语和同位语。

因此,名词性从句可分为主语从句、表语从句、宾语从句和同位从句。

(一)主语从句1、主语从句在复合句作主语。

e.g. Who will go is not important.2、用it作形式主语,主语从句放在句末。

e.g. It doesn’t matter so much whether you will come or not.注意:that引导主语从句时,不能省略。

e.g. That he suddenly fell ill last week made us surprised.(二)表语从句1、表语从句在复合句中作表语,位于系动词之后。

e.g. The question was who could go there.注意:引导表语从句的连接词that有时可省去。

e.g. My idea is (that) we can get more comrades to help in the work.(三)宾语从句1、宾语从句在复合句中作宾语。

引导宾语从句的连词that一般可省略。

e.g. I hope (that) everything is all right.2、介词之后的宾语从句,不可用which或if连接,要分别用what 或whether。

e.g. I’m interested in whether you’ve finished the work..I’m interested in what you’ve said.注意1:whether与if都可以引导宾语从句,常可互换。

但下面情况不能互换。

①宾语从句是否定句时,只用if,不用whether。

e.g. I wonder if it doesn’t rain.②用if 会引起误解,就要用whether。

e.g. Please let me know whether you want to go.(此句如果把whether改成if,容易当成条件句理解)③宾语从句中的whether 与or not直接连用,就不能换成if;不直接连用,可换。

e.g. I don’t know whether or not the report is true.I don’t know whether/ if the report is true or not.注意2以下情况只能用whether⑴介词后的宾语从句要用whether引导⑵whether 可与不定式连用⑶whether也可引导主语从句、表语从句、同位语从句,让步状语从句,以上从句中均不能换成if⑷宾语从句中的whether 与or not直接连用e.g. It depends on whether we have enough money.They don’t know whether to go there.(四)同位语从句同位语从句在句中作某一名词的同位语,一般位于该名词(如:news, fact, idea, suggestion, promise等)之后,说明该名词的具体内容。

e.g. I have no idea when he will be back.The fact that he had not said anything surprised everybody.1.同位语从句的功能同位语从句对名词进一步解释,说明名词的具体内容,一般由that 引导。

如:The king’s decision that the prisoner would be set free surprised all the people.国王作出的这名囚犯释放的决定让人们大吃一惊。

2.同位语在句子中的位置同位语从句有时可以不紧跟在它所说明的名词后面,而是被别的词隔开。

如:He got the news from Mary that the sports meeting was put off.他从玛丽那里得知运动会要延期举行。

3.同位语从句与定语从句的区别1)定语从句中的that既代替先行词,同时在从句中作某个成分(主语或宾语),而同位语从句中的that是连词,只起连接主句与从句的作用,不充当句中任何成分。

2)定语从句是形容词性的,其功能是修饰先行词,对先行词加以限定,描述它的性质或特征;同位语从句是名词性的,其功能是对名词进行补充说明。

如:The news that he told me is that Tom would go abroad next year.他告诉我的消息是汤姆明年将出国。

(第一个that引导的从句是定语从句,that在从句中作宾语)The news that Tom would go abroad is told by him.汤姆将出国的消息是他讲的。

(同位语从句,that在句中不作任何成分)考点二名词性从句的关联词分类:1.从属连词:that, whether, if, as if注意:that, whether, if, as if。

that 无词义,在从句中不担任成分,有时可省略;if (whether), as if虽有词义,但在从句中不担任成分。

Eg: The question is whether it is worth doing.My hope is that she will soon be well again.(表语从句)Everybody hopes that she will soon be well again.(宾语从句)That she will soon be well again is our hope.(主语从句)需要注意的是:引导主语从句,表语从句和同位语从句的情况,that是不可以省略的2.连接代词:who, whom, whose, what, which, whoever, whomever, whatever, whicheverEg:Who will take his place is unknown.That is what he is worried about.I have no idea which team will win.注意:连接代词有词义,在从句中担任成分,如主语、表语、宾语、或定语等。

3.连接副词:when, where, why, how, whenever, wherever, however Eg:Where she has gone s not known yet.Please tell me when we shall discuss our work plan.This is why he is late.You have no idea how worried I was.注意:连接副词有词义,在从句中担任成分,作状语。

总结:连接代词与连接副词在句中不再是疑问句,因而从句中谓语不用疑问式,而应用陈述语序。

连接代词与连接副词在从句充当句子成分,连接词whether 和if(是否),as if(好象)在从句中不充当句子成分,只起连接作用。

根据句义,如果连接代词与连接副词,whether、if 和as if都用不上时,才用that作连接词(that本身无任何含义)。

考点三that 和what 引导的名词性从句that和what都可以引导名词性从句,但that是连接词,本身无词义,仅起连接作用,不在从句中担任任何成分;what是连接代词,不仅引导名词性从句,而且在从句中充当一定的成分,如主语、宾语或表语。

如:That he stole a bike was true.他真的偷了一辆自行车。

The important thing is what you do, but not what you say.重要的是你做什么,而不是说什么。

考点四if和whether引导的名词性从句whether和if均可引导动词后的宾语从句,常可互换。

但从句中有or not时或介词宾语从句中只能用whether连接。

其他名词性从句,如主语从句、表语从句、同位语从句只用whether连接,不用if。

如:I don’t care about whether you have money or not.我并不在意你是否有钱。

介词后的宾语从句一般不用which和if引导,要用whether和what。

that也很少引导介词宾语从句,只在except, but, besides等之后才用。

如:I could say nothing but that I was angry.我无话可说,只是感到生气。

考点五“疑问词”及“疑问词+ever”引导的名词性从句1.如何选择这些引导词呢?根据它们的意思和从句所缺的成分进行选择(1)who意为“谁”,在从句中可以用作主语、表语或宾语。

(2)whom意为“谁”,在从句中用作宾语,一般可以用who来取代,但在介词后面时只能用whom。

(3)whose意为“谁的”,在从句中用作定语。

(4)which意为“哪一个”,在从句中用作定语。

(5)when意为“什么时候”,在从句中用作时间状语;where意为“哪里”,在从句中用作地点状语;how意为“怎样,多么……”,在从句中用作状语;why意为“为什么”,在从句中用作原因状语。

2.连接代词whoever,whatever,whichever可引导名词性从句,相当于anyone who, anything that等。

他们也可以引导让步状语从句,相当于no matter who/ what/ which。

如:Whoever breaks the law should be punished. 任何违法的人都要受到惩罚。

3.who / whoever, what / whatever等的用法区别一般说来,what/who等含特指意义,而whatever/whoever等含泛指意义,意为“无论什么/无论谁”,相当于anything that.../anyone who...。

如:Whoever wants to go may go.无论谁想去都可以去。

Do you know who can repair a bike?你知道谁会修自行车吗?You can have whatever food you want.你想吃什么都可以。
