【最新】2018届高考英语语法精品教案:专题十一 名词性从句

名词性从句一直备受高考命题者的关注,近几年来的高考题主要考查在具体语境中连接词的选择,尤其是连接词what和that的辨析,以及whether 与if表示“是否”时的区别。

因此,正确区分名词性从句的类型,根据在从句中的作用和所表达的意义,确定恰当的连接词是一轮复习的重点。

此外,名词性从句和定语从句的辨析,也是高考考查的重点。

一、认识各种名词性从句名词性从句相当于名词,可分别作句子的主语、表语、宾语和同位语。

因此,名词性从句具体分为主语从句、表语从句、宾语从句和同位语从句。

名词性从句中的连接词有连词that / whether / if,连接代词what / who(m>/ which / whose / whatever / whoever / whomever / whichever,连接副词where / when / why / how 。

b5E2RGbCAP从名词性从句在句中所起的作用来说,名词性从句是句子不可缺少的一部分,和句子的其他成分之间也不会用逗号隔开。

而定语从句和状语从句是句子中的修饰成分,去掉之后不会影响句子主体结构的完整性。

这是判断是否是名词性从句最主要的特征。

如:p1EanqFDPwI wonder how much these shoes cost. (宾语从句,不可省去>He is the very man I look after. (定语从句,修饰the man>You may borrow the book as long as you keep it clean. (状语从句>DXDiTa9E3d1.主语从句Who will go is not important.It doesn't matter so much whether you will come or not. (形式主语it代替后面的真正的主语从句>RTCrpUDGiT注意:that引导主语从句放于句首时,不能省略。

2018版高考英语二轮教师用书:第1部分 专题1 第4讲 名词性从句含解析

第四讲名词性从句(对应学生用书第12页)1.(2017·江苏高考卷)We choose this hotel because the price for a night here is down to $20,half of________ it used to charge.A.that B.whichC.what D.howC[句意:我们选择这家旅馆,因为这里一晚的价格降到了20美元,这是他们过去所收价格的一半。

空处在句中引导宾语从句,且在宾语从句中作charge的宾语,因此只能选择what。

half of what it used to charge“它过去所收价格的一半”。

]2.(2016·江苏高考卷)It is often the case________ anything is possible for those who hang on to hope.A.why B.what C.as D.thatD[句意:通常,对于那些心怀希望的人来说,一切皆有可能。

it在句中是形式主语,that anything is possible for those who hang on to hope是主语从句,在句中作真正的主语。

由于主语从句中不缺少主语、宾语或表语,故用that引导主语从句。

]3.(2014·江苏高考卷)—What a mess! You are always so lazy!—I'm not to blame,Mum.I am________ you have made me.A.how B.what C.that D.whoB[句意:——真是一团糟!你总是这么懒!——妈妈,不该责备我。

高三英语高考二轮复习名词性从句讲练学案全国通用

2010届高考二轮复习名词性从句讲练学案在句子中起名词作用的句子叫名词性从句(Noun Clauses)。

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、介词宾语等,因此根据它在句中不同的语法功能,名词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。

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。

被强调部分指人时也可用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.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It seems that… 似乎…It happened that… 碰巧…It appears t hat… 似乎…(4) It +过去分词+从句It is reported that… 据报道…It has been proved that… 已证实…It is said that… 据说…主语从句不可位于句首的五种情况:(1)if 引导的主语从句不可居于复合句句首。

10.(2015·北京卷,35)___H_o_w___ we understand things has a lot to do with what we feel.
解析:句意:我们理解事物的方式与我们的认知有很大关系。“________ we understand things”为主语从句,该从句中缺少方式状语(如何),故用How。
如:What(=The thing that)you said was right.你所说的是正确的。
03
高效演练





连接副词:how,however,where,wherever,when,
whenever,why等,各自有意义,在从句中作状语。
要点: 1.主语从句作主语,主句谓语动词通常用单数;为使句子平衡,常用it作形式 主语。 2.表语从句还可以用as if,as though引导。 3.表示“是否”,引导宾语从句时可用if或whether,但在介词后或直接与or not连用时,只能用whether引导;引导表语从句、同位语从句或位于句首的主语从 句时,只能用whether,不用if。 4.同位语从句一般放在fact,news,idea,promise,suggestion,advice等抽象 名词之后,说明或解释这些抽象名词的具体内容。多用that引导,不能由which引 导。
8.what可引导名词性从句但不能引导定语从句。what引导名词性从句时,在句 中不能省略,具有意义,表示“……的东西/事情/人/时间/地点等”,它引导名词性 从句时不仅起引导作用,同时还要作句子中的某个句法成分。what=the thing/the place/the person/the time that...

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…;(2)It is (was) suggested (demanded, wished, desired…)that…等。

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 place that…; what=the time that…; what=the person that…等。

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。

that在定语从句中充当句子成分,可指物或人;而同位语从句中的that在从句中不充当任何句子成分,只起连接作用。

请比较:(1)The news (that/which) he told us was exciting.(定语从句,that/which在从句中作宾语,还可以被省略)(2)The news that our team has won is exciting.(同位语从句,that从句是说明news的内容的,that在从句中不作任何成分,但不能被省略)辨析判断是定语从句还是同位语从句可以用“加词”的方法,即在名词和从句之间加入一个be动词,如果句子意思成立,则是同位语从句,否则,则是定语从句。

如上面第二句,加上be动词后:The news is that our team has won.句子意思成立,所以是同位语从句。

而第一句,加上be动词后:The news is that he told us.意思不成立,因此不是同位语从句。

【特别提醒】一般情况下,同位语从句紧跟在它所说明的名词的后面,可是有的时候,为了表达的需要,名词与从句之间被另外一些内容分隔开了,叫做“分隔同位语从句”。

对于这类同位语从句,一定要根据句意,找准它所说明的名词。

2.定语从句与状语从句请看两组句子:第一组:区分such...as...和such...that...(1)The new storybook is written in such easy English as beginners can understand.(2)The new storybook is written in such easy English that beginners can understand it.这两句话只有一词之差,但语法结构大相径庭:第一句是as引导的定语从句,as相当于that/which(但不能用that/which),在从句中作understand的宾语。

第二句是结果状语从句,that在从句中不作成分。

结论:当从句缺少句子成分时,用such...as...;当从句不缺少句子成分时,用such...that...。

第二组:选用in which, where填空(1)He left the key ______ he had been an hour before.(2)He left the place ______ he lived for many years.分析:第一句只能填where, where引导的是地点状语从句,修饰主句中的谓语动词。

此处where不可换成in which,因为in which只能引导定语从句,本句中根本就没有先行词(后面的从句不是修饰key的)。

第二句填where或in which。

根据句意可知,后面的句子是对名词place的修饰,因此此句是定语从句。

二、that与what的区别that引导名词性从句,在从句中不作任何成分,that本身无意义,只起连接作用。

what 引导名词性从句时,在从句中可以作主语、宾语、表语等,what表示“……的东西或事情”。

请比较:What I need is more time.(what引导主语从句,在从句中作宾语)That I need more time to do the work is very clear.(that引导主语从句,在从句中不作任何成分)The village is no longer what it used to be.(what引导表语从句,在从句中作表语)I had no idea what we should do next.(what引导同位语从句,在从句中作宾语)He will tell us what he saw in London.(what引导宾语从句,在从句中作宾语) 精析名词性从句中区分that与what的关键是:分析句子结构,看从句是否缺少句子成分。

如果不缺成分,就用that,如果缺少句子成分(主语、宾语、表语等),且表示“……的东西或事情”就用what。

三、who, whoever与no matter who的区别引导名词性从句,在句中作主语时用who,意思是“谁”,含有疑问意味,whoever意为“无论谁”,不含有疑问意味。

whoever在引导名词性从句时,相当于anyone who,其中who引导一个定语从句紧随其后。

另外,whoever还可以引导让步状语从句,这时whoever相当于no matter who,但是no matter who只能引导让步状语从句。

请比较:1.Who has taken away my bag is unknown.谁拿走了我的包还不知道。

(若用whoever显然句意不通)2.Whoever breaks the law will be punished.无论谁违反法律都要受到惩罚。

(whoever表达的语气强烈)3.I'm not going to let you in, no matter who you are.=I'm not going to let you in, whoever you are.(根据句意“我不会让你进去的,不管你是谁”,后面是一个让步状语从句,故用no matter who或者whoever)【特别提醒】wh-ever既可引导名词性从句,又可引导让步状语从句。

引导名词性从句时,whoever =anyone who; whomever=any­one whom; whatever=anything that; whichever=anything/anyone that; whosever=any one whose。

Whichever he likes will be given to him.=Anything that he likes will be given to him.无论他想要哪个都可以给他。

You should give the book back to whosever name(=anyone whose name) is on the cover of it.你该把书还给任何一个他的名字在封面上的人。

【方法技巧】做题时,具体思路如下:①通读全句,首先考虑是不是某种句型,如强调句型;②题干句若是疑问句,首先把它恢复为正常语序;③观察设空的前前后后,确定相关从句的性质;④确定从句性质后,回忆相关从句的用法特点,从而作出取舍;⑤注意标点符号和并列连词(and, but)的作用;⑥将选项代入句子,看前后是否语意贯通。

考点一、考查宾语、表语从句例1. (2017·江苏) We choose this hotel because the price for a night here is down to $20, half of ____________ it used to charge.A. thatB. whichC. whatD. how【答案】C【解析】考查宾语从句。

"half of _________ it used to charge"是$20的同位语,即原来价格的一半是现在的$20;另外,of后跟名词或名词短语构成介宾短语,所以,这里是宾语从句;宾语从句中的charge后面缺少宾语,所以用what来引导宾语从句,并充当宾语从句的宾语,故选C。
