1、专题11 名词性从句考点题型 技巧考向分析名词性从句是高考的热点,对于名词性从句考纲要求掌握以下内容:掌握主语从句、宾语从句、表语从句的基本用法,了解同位语从句的基本用法。要求考生在复习备考中应该掌握名词性从句的基本用法;一些易混引导词的辨析;句子的语序、否定前移;名词性从句和定语从句、状语从句的辨析等。复习建议1. 掌握宾语从句的用法;2. 了解同位语从句的用法;3. 掌握表语从句的用法;4. 掌握主语从句的用法;5. 如何正确选择引导词。考点导航考点01 名词性从句连接词的用法名词性从句的连接词有从属连词that/whether/if,连接代词what/who/which/whose/wh
2、atever/whoever/whomever/whichever,连接副词where/when/why/how/wherever/whenever。1.that的用法。(1)主语从句、表语从句、同位语从句中用that但不能省略。(2)一般情况下,宾语从句中的引导词that可省略,但在以下几种情况中that一般不省略:当that从句和主句谓语动词之间有插入语时;有多个that引导的从句时,第一个that可以省略,而其他的that常不可省略;介词except,but,besides,in等后跟that引导的宾语从句时;当when,who,what,where,why,how等引导的从句与that
3、引导的从句作主句谓语动词的并列宾语时。(3)that和what的区别。that 引导名词性从句时,在主从句中不担当任何句子成分,也没有任何含义;而what引导名词性从句时,在主从句中都要充当一定的句子成分,what可以分解成定语从句中的先行词关系代词,即常说的先行词that。(4)同位语从句与定语从句中that的区别。同位语从句中的连接词that只起连接作用,在从句中不担当任何句子成分;而定语从句中的关系代词that在句中作宾语或主语,与先行词有修饰关系。如果句子是同位语从句,就应用连接词that而不能用which。同位语从句一般放在表具体含义的名词后解释说明名词的含义或内容,如以下名词:ne
4、ws,fact,suggestion,truth,plan,belief,doubt,possibility,idea等,而定语从句只是对先行词的限定和修饰。2.whether和if的用法。It all depends on whether they will come back.(2)后面直接跟or not 时用whether。(3)主语从句、表语从句中只能用whether。(4)whether可以引导同位语从句,用以说明前面的名词的内容,if则不能。(5)whether常与or连用表示一种选择,if不能这样用;whether也可与动词不定式连用但if不能。(6)间接宾语位于句首时或者间接宾
5、语提前时用whether不用if。(7)whether可引导一个让步状语从句表示不管、无论,而if不能。3.疑问词ever和no matter疑问词的区别。(1)疑问词ever可引导名词性从句,在主从句中要充当一定的成分。(2)疑问词ever还可引导让步状语从句。(3)no matter疑问词只能引导让步状语从句。4.when和where引导的同位语从句与定语从句的区别。when 和where前面的名词若是表示时间、地点的名词,则when和where引导的是定语从句,否则则为同位语从句。5.名词性从句中that不宜省略的几种情况宾语从句或表语从句中that有时可以省略,但在以下情况时,that
6、不宜省略。 (1)当动词后带有两个并列的宾语从句时,引入第二个从句的连词that不可省略。如: (2)当that前面有插入语时,that不宜省略。如: (3)省略答语中,that宾语从句单独出现时,that不可省略。如: (4)当主句的状语部分位于that 宾语从句之前时,that不宜省略。如: (如省略that,at once也可能修饰从句,是表示立刻意识到,还是表示立刻去处理,较为含糊) (5) 当that 宾语从句中的状语部分位于从句的前部时,that不宜省略。如: (6)当that 宾语从句是双宾语中的直接宾语时,that一般不宜省略。如: (7)当为了强调而把that引导的主语从句位
7、于句首时,that不可省略。如: (8)当主句中的谓语动词是固定词组时,其宾语that从句中的 that 不宜省略。如: (9)当that 宾语从句前有 it作其形式宾语时,that不可省略。如: (10)当引导同位语从句时,that一般不可省略,尤其当that与先行词处于分割情况时。如: (11)当that 宾语从句的主语是非谓语动词或是主语从句时,that不可省略。如: 考点02 主语从句 1.主语从句在复合句中充当主语,大多数主语从句都可以用it作形式主语而把主语从句置于句尾。2.that引导主语从句时可用it作形式主语,that不可省;what引导的主语从句表示的东西时,一般不用it作
8、形式主语;whatever,whoever,whichever一般也不用it作形式主语。注意:(1)在It is necessary/important/strange/natural.that从句结构中,从句谓语常用(should)动词原形形式。【拓展延伸】主语从句的引导词引导词作用引导词作用that无词义,在从句中不充当成分,但不能省略how多么,怎样,作方式状语或程度状语who谁,作主语、宾语when何时,作时间状语whom谁,作宾语where在哪儿,作地点状语what什么,可作主语、宾语、表语、定语why为什么,作原因状语which哪一个,哪些,作主语、宾语、定语whether是否【特
9、别注意】当作主语的句子太长时,为保持句子平衡,常用it作形式主语,而将真正的主语置后。if是否,不可直接引导主语从句(用it作形式主语时可以) 。3. 主语从句的特殊用法(1)主语从句与定语从句的转换(2)几个特殊句型之间的转换考点03宾语从句【难点梳理】引导宾语从句的连接词主要有:连接词:that,whether,if等连接代词:what,who,whose,whatever,whichever,whoever等连接副词:when,where,why,how等1. 连接词that,whether,if引导注意:whether/if都意为是否。一般情况下,它们可以互换,口语中常用if,但以下情
10、况中,只能用whether。(1)与or not紧接连用时。(2)作介词的宾语从句时。2. 连接代词what,who,whose,whatever,whichever,whoever等引导3. 连接副词when,where,why,how等引导4. 宾语从句的语序在宾语从句中要用陈述句语序。5. 宾语从句的时态(1)当主句的谓语动词是一般现在时时,其宾语从句的时态可以是任何适当的时态。(2)当主句的谓语动词是一般过去时时,其宾语从句的时态一般要用适当的过去时态。(3)当宾语从句是表达客观真理和规律的句子时,其时态仍旧用一般现在时。注意:在使用宾语从句时需要注意下面几点:动词find,feel,
11、think,consider,make,believe,guess,suppose,assume等后有宾语补足语时,则需要用it作形式宾语,而将that宾语从句后置。hate,like,take,owe,have,take for granted等表示喜欢;痛恨;认为的动词或动词短语和see to表示注意,留意后有宾语补足语时,需要用it作形式宾语而将宾语从句后置。介词后的宾语从句。宾语从句的否定转移。将think,believe,suppose,expect,fancy,imagine等动词后面宾语从句的否定词转移到主句中,即主句的谓语动词用否定式,而从句的谓语动词用肯定式。【巧学妙记】宾语
12、从句的用法速记口诀宾语从句须注意,几点事项应牢记。一是关键引导词,不同句子词相异。陈述句子用that;一般疑问是否(if,whether)替;特殊问句更好办,引导还用疑问词。二是时态常变化,主句不同从句异。主句若为现在时,从句时态应看意;主句若为过去时,从句时态向前移。三是语序要记清,从句永保陈述序。考点04表语从句引导表语从句的连接词主要有:连接词:that,whether连接代词:who,whom,whose,which,what,whoever whomever,whichever,whatever连接副词:when,where,how,why 1. 连接词引导2. 连接代词和连接副词引
13、导注意:(1)as/as if/as though引导的表语从句常跟在特定动词后面,如seem,appear,look,taste,sound,feel等。(2)当主句的主语是reason时,表语从句一般由that引导,这种用法常见于句型The reason why. is that. 考点05同位语从句1. 同位语从句跟在名词后面,进一步解释、说明该名词的具体内容。同位语从句常跟在名词idea, fact, news, hope, thought, suggestion等抽象名词之后;2. 连接词that不能省略,无意义无成分; 3. 用whether而不用if引导同位语从句;4. 连接代词
14、who(m), which, what,whose在从句中作主语、宾语、表语或定语;5. 连接副词where, when, why, how在从句作状语。6.分割式同位语从句:同位语从句有时被别的词或短语把它和名词隔开:(谓语较短,同位语从句较长)。7.若被同位语从句说明的名词是:advice, suggestion, proposal(建议), demand, request, requirement, order(命令)等表示建议、命令、要求的词时,同位语从句的谓语用(should)+do。8.区别由that 引导的定语从句和同位语从句:定语从句中的that是代词,可在从句中作主、宾、表;
15、同位语从句中的that是连词,无成分无意义;定语从句说明先行词的性质与特征,与先行词是修饰与被修饰的关系;同位语从句对名词即先行词加以补充说明,是名词全部内容的体现。在名词和从句之间加be, 使之构成一个新句子,如果合乎逻辑,句子通顺,则是同位语从句,定语从句是不能用系表结构把先行词与从句连接起来的。【题型分析】1.The gold medal will be awarded _to wins the first place in the bicycle race.A. whomever B. whereverC. whoever D. whatever2.
