1 从高考试题谈名词性从句的考查及复习 名词性从句主要起名词所起的作用,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,但仔细分析高考试题不难看出,这一部分内容主要从以下几个方面进行考查。 I.语序问题 在名词性从句中,除了关联词在从句之首外,其它部分应用陈述句的语序,而考生们往往使用疑问句的语序,特别是在以wh-引起的名词性从句中。克服这个问题的关键就是要找准从句的主语。例如: 1、The photographs will show you ____ .(MET89) A. what does our village look like B. what our village looks like C. how does our village look like D. how our village looks like [解析]答案:B。根据引导词在从句中作介词like的宾语,所以不能用副词how,排除C、D,而A项用了疑问句的语序,故选B项。再如: 2、He asked ____ for a violin.(MET92) A. did I pay how much B. I paid how much C. how much did I pay D. how much I paid 3、Someone is ringing the doorbell. Go and see ____. (全国2000) D A. who is he B. who he is C. who is it D. who it is 4、 The photographs will show you ____.(MET1989) B A. what does our village look like B. what our village looks like C. how does our village look like D. how our village looks like 名词性从句中都用陈述语序,不用倒装语序。题3中的干扰项是B,对想要知道的人提问或应答都用 it 而不用人称代词 he, I , you 等。题4只要注意是介词宾语就行了。 5、Someone is ringing the doorbell. Go and see ____. (全国2000) D A. who is he B. who he is C. who is it D. who it is 6、 The photographs will show you ____.(MET1989) B A. what does our village look like B. what our village looks like C. how does our village look like D. how our village looks like 名词性从句中都用陈述语序,不用倒装语序。题5中的干扰项是B,对想要知道的人提问或应答都用 it 而不用人称代词 he, I , you 等。题6只要注意是介词宾语就行了。 II.用it 代替主语从句或宾语从句 为了使句子保持平衡,常用先行词it来代替主语从句或宾语从句,而把主语从句或宾语从句放到后面,尤其是连词that引导的主语从句常用于此种句式中,但what,whatever,whoever,whichever引导的主语从句一般不后置。例如: I hate ____ when people talk with their mouths full.(MET98) A.it B.that C.these D.them [解析]答案:A。此题考查了it作先行词代替宾语从句,而把宾语从句放在句末。其它人称代词或指示代词都不能代替从句。再如: Does __ matter if he can't finish the job on time?(MET91)D A.this B.that C.the D.it 1、_____ is a fact that English is being accepted as an international language. (NMET1995) D A. There B. This C. That D. It 2

2、 I like______ in the autumn when the weather is clear and bright. (04全国I) C A this B that C it D one 3、The chairman thought ______ necessary to invite Professor Smith to speak at the meeting. (05全国卷1) A.that B.it C.this D.him B 主语、宾语从句常用先行词 it 代替,而将其置于句末。但由 whatever, whoever 引导的主语从句一般不用 it 代替。 III.关联词的区分 名词性从句中关联词的选择是非常重要的,所以在高考中更多的是考查关联词的选择问题。而在关联词的选择中,主要侧重以下几个方面的检测。 (I)whether 和if 的区别以及whether,if 和that 的区别。 whether 和 if 在引导宾语从句时一般可以通用,但在引导主语从句、表语从句、同位语从句、介词后面的宾语从句时只能用whether,不能用if ;whether,if 引导的名词性从句和 that 引导的名词性从句的区别在于: whether,if 引导的从句是由一般疑问句转化而来的,含有疑问意义,而 that 引导的从句是由陈述句转化而来的,不含有疑问意义。 例如: What the doctors really doubt is _______ my mother will recover from the serious disease soon.(上海2001年春季招生) A.when B.how C.whether D.why [解析]答案:C。这是一个表语从句。根据 doubt 一词可知,所怀疑的应是是否能治好病,所以要填whether。这句话的意思是“医生真的怀疑我妈妈是否能很快从重病中恢复过来。”再如: 1、 It worried her a bit ____ her hair was turning grey.(MET92)B A.while B.that C.if D.for 2、 ____ we'll go camping tomorrow depends on the weather.(NMET96)B A.If B.Whether C.That D.Where 3、 What the doctors really doubt is _____my mother will recover from the serious disease soon. (上海2001) C A. when B. if C. whether D. why 4、 Elephants have their own way to tell the shape of an object and _______it is rough or smooth. (05天津卷)B A. 不填 B. whether C. how D. what 在名词性从句中表示“是否”这一概念时,连词 if 一般只能引导宾语从句,而题3是表语从句,故不能选B;注意doubt 的用法,如果是肯定句,用 whether,如果是否定句,用 that。宾语从句中,以下情况只用 whether 不用 if:① 与 or 连用时;② 后接不定式短语时;③ 在 decide ; be sure 等动词后。 (II)that 从句与 wh- 从句的区别: that连词在从句中不作成分,不含有疑问意义,而wh-连词在从句中作成分,且含有疑问意义。 1. ____ we can't get seems better than ____ we have.(NMET96) A. What , what B. What , that C. That , that D. That , what [解析]答案: A。此题考查了两个名词性从句, 因为从句中都缺宾语, 所以都应选what不选that, that在引导名词性从句时不作成分。 2. — Do you remember ____ he came? — Yes, I do. He came by car. (NMET94)A A. how B. when C. that D. if [解析]答案: A。根据答语He came by car可知, 问句应是提问方式, 所以选择A, how。 再如: ______ he said at the meeting astonished everybody present.(NMET93)A 3

A. What B. That C. The fact D. The matter 3、 Great changes have taken place in that school. It is no longer ______ it was 20 years ago, _____ it was so poorly equipped. (05安徽卷) A A. what; when B. that; which C. what; which D. which; that 前句考查的是 that 与 what 的区别。that 在名词性从句中不充当任何成分,而 what 可充当名词性的成分。前句的表语从句中还缺少表语,故只能用 what。后句是定语从句,修饰 20 years ago,所以须用 when。 (III)what,which,who,when,where,how等引导的名词性从句与whatever,whichever,whoever,whenever,wherever,however等引导的名词性从句的区别: 后者引导的名词性从句不含有疑问意义,相当于名词后加一个定语从句,而前者引导的名词性从句都含有疑问意义。who / whom, whoever / whomever的选择,要看关联词在从句中是作主语还是作宾语而定,如果在从句中作主语只能选用 who / whoever,作宾语时用whom / whomever。例如: 1. It is generally considered unwise to give a child ____ he or she wants.(NMET97)B A. however B. whatever C. whichever D. whenever [解析]答案: B。根据句意可以看出后面的从句应是一个宾语从句,而从句中 wants 缺少宾语, 排除 A 和 D ,whichever 表示“无论哪一个, 无论哪些”, 应表示一定范围内的人或物, 此处没有涉及事物的范围, 所以应选 B.whatever,表示“无论什么”。 2. ____ leaves the room last ought to turn off the lights.(MET88) C A. Anyone B. The person C. Whoever D. Who [解析]答案: C。此题不含有疑问意义, 所以用whoever 引导主语从句, 强调“无论谁”。whoever 在从句中作主语。 3、______ leaves the room last ought to turn off the lights. (MET1988) C A. Anyone B. The person C. Whoever D. Who whoever 引导名词性从句时表示“无论哪一个”,相当于 anyone who;who 引导名词性从句时表示带有疑问的“谁”。根据该题的意思不难作出选择。选项A, B后都缺少了 who,而引导定语从句的 who 是不能省略的。同时还需要注意 whoever 与 no matter who; whatever 与 no matter what 等的区别。wh-ever 既可引导名词性从句也可引导状语从句,而 no matter wh- 只能引导状语从句。 1) I was surprised by her words, which made me recognize ___silly mistakes I had made. (05湖南卷) A A. what B. that C. how D. which 2) Parents are taught to understand ______ important education is to their children’s future. (04广东) B A. that B. how C. such D. so what 与 how 引导感叹句时,what 后加名词,how 后加形容词和副词。其结构为:What + (a) + (adj.) + n. 但要注意在 what 后不能加表示数量的 many; much; few; little 等词。 How + adj. + (a )+ (n.),要注意的是 how 后的名词只能为单数名词。题1中是复数名词,只能用 what;题2中的正常语序是 …education is important to their …,所以选B。 (IV) who, what, which, how, when, where之间的词义区别以及whoever, whatever, whichever, however, whenever, wherever等之间的词义区别。 这主要从两个方面来区分:一是分析句子结构,看其在从句中作什么成分;二是理清其在句中的含义。例如: 1. A computer can only do ____ you have instructed it to do. C
