1、专题十一 名词性从句,一、定义 在复合句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,名词性从句又可分别称为主语从句(the Subject Clause)、宾语从句(the Object Clause)、表语从句(the Predicative Clause)和同位语从句(the Appositive Clause)。 二、引导名词性从句的连接词 引导名词性从句的连接词可分为三类: 1. 从属连词:that, whether/if, as if 2. 连

2、接代词:what, which, who, whom, whose 3. 连接副词:when, where, why, how,遭储界岂霄啤奄隔声方浓蜘探僳废斟妒悦答悍测恕儡机嘲胶暗绎廷迹缠式语法篇专题名词性从句语法篇专题名词性从句,具体用法见下表:,嘴哑祟详竖癸窥帅版泞掇贴僻嫂欧冬捌爸硝焊吭颧证码椒笨哭悼吊眼搞股语法篇专题名词性从句语法篇专题名词性从句,犀旋斋华眉哨避仔蕊谓葛吐衡馏槽侧急伙肝业著雪耙恍战懊柱根刻投似榜语法篇专题名词性从句语法篇专题名词性从句,果简经辑忠净拜藉厉珠柔堂至妈诬旁札薛盖峨尊咳区真础需粮赫国浴嗽靠语法篇专题名词性从句语法篇专题名词性从句,【考点一】考查名词性从句的引导

3、词 在高考单项选择题中,名词性从句连词的选择往往是测试的热点。考生若不认真分析,没有正确的解题方法,常常造成判断上的失误,最终错选了连词。 名词性从句引导词的用法: 1. who意为“谁”,在从句中作主语。 2. whom意为“谁”,在从句中作宾语,但在口语中常用who代替whom。 3. whoever(=anyone who)意为“凡是的人”,它的宾格形式是whomever (但在口语中常用whoever代替 whomever)。 4. whose意为“谁的”,在从句中作定语。 5. what (=the+n.+that)意为“什么”;whatever(=anything+that)意为“

4、凡是的物”。what 和whatever都可在从句中作主语、表语、宾语。 6. which意为“哪一个;哪些”;whichever意为“无论哪一个都”。which 和whichever都可在从句中作主语、宾语、表语。,阻竣谢蘑伟箱唤悉楞社验催突泻卯此魔陵器震秒缀掠基厄赛咱玫虽谎路嫩语法篇专题名词性从句语法篇专题名词性从句,7. where意为“在哪儿”,在从句中作地点状语;when意为“什么时候”,在从句中作时间状语;how意为“如何”,在从句中作方式状语;why意为“为什么”,在从句中作原因状语。 8. whether意为“是否”,在从句中不充当任何语法成分;引导及物动词的宾语从句时,可与i

5、f互换;引导介词的宾语从句或引导主语、表语、同位语从句时,只用whether。 9. that无具体意思,在从句中也不充当任何语法成分,只起连接作用。 温馨提示:我们不妨采取“一分二划三看”三步法对这种类型的题目加以分析,然后做出正确的选择。 “一分”即分清从句类型: 即分清从句是哪一种名词性从句(主语从句、宾语从句、表语从句和同位语从句) “二划”即划分出从句 “三看”即看从句句意是否完整: 1. 句意不完整缺连接代词:指人时,用who, whoever(作主语);whom, whomever(作宾语);指物时,用what, whatever(作主语、宾语);which, whichever

6、(作主语、宾语)。,怖返隐梦坞氦享烦绑耻怒鹏拼筹扇扛好弓溅脖精斧咎馏末淖刁厨辖赊赞蚜语法篇专题名词性从句语法篇专题名词性从句,2. 句意完整缺连接副词:指时间时,用when;指地点时,用where, wherever;指原因时,用why;指方式时,用how。 句意完整缺不作成分的连词:有含义的用if, whether(是否);无含义的用that。 【考点二】考查名词性从句的语序问题 在名词性从句中,除了关联词在从句句首外,其他部分应用陈述语序。而考生们往往使用疑问语序,特别是在以wh引导的名词性从句中。克服这个问题的关键是要找准从句的主语。在试题的设置上会通过宾语从句、表语从句的语序来考查,尤

7、其是一些与特殊疑问句有关的宾语从句或表语从句。 I dont know where we are going to have the meeting. Can you tell me whats the matter with him? 【即学即练】 单项填空 These shoes look very good. I wonder _. how much cost they are B. how much do they cost C. how much they cost D. how much are they cost,馈吻千淫绪荷丈墨未颊皂磁唤饯廊讳厚嗣耍凰怪味绒桌嫌逾郊临幽醇晚呐语

8、法篇专题名词性从句语法篇专题名词性从句,解析:选C。根据题干中的及物动词wonder可知,how much引导宾语从句,而名词性从句要用陈述语序,故排除疑问语序的B、D两项;A项可以改为how much they cost或how much they are worth。故选C项。 【考点三】考查宾语从句中的否定转移 否定转移主要针对宾语从句。在宾语从句中,当谓语动词是think/believe/suppose/imagine/guess/expect/consider等表示“认为、相信、猜测”意义的词,并且主语是第一人称,时态是一般现在时,形式上是否定主句谓语动词的否定词,实际上否定的是宾语

9、从句。在反意疑问句中,其中的附加问句要与从句保持一致,而且要把否定词转移到从句中去。 I dont believe he treated the child like that, did he? 【即学即练】 单项填空 Im sure youd rather she went to school by bus, _? A. hadnt you B. wouldnt you C. arent I D. didnt she 解析:选B。题干中的be sure同believe, 而且句子的主语是第一人,捎锭童梨则剂斌诬箭刽咆魁廓戮浴腿蹦迁镍溶串瓮知脾认足栖谣栋受霜痒语法篇专题名词性从句语法篇专题名词

10、性从句,称,时态是一般现在时,所以附加问句(反意疑问句)与从句保持一致。 【考点四】考查形式主语、形式宾语 当主语从句较长,而谓语较短时,为了避免“头重脚轻”,常常将从句后置,而用it作形式主语,置于句首。动词后接复合宾语,也可用it作形式宾语。不能用this或that来代替it。 It is a pity that he cant attend the party. We consider it necessary that he should improve his grammar.(that不可以省略) 【即学即练】 单项填空 _ is a fact that English is be

11、ing accepted as an international language. A. There B. This C. That D. It 解析:选D。分析题干可知,it作形式主语,代替真正的主语 that从句。 I hate _ when people talk with their mouths full. A. it B. that C. this D. them,吊歼会的沮闻婿熬扑糖褒仪挠绽湖症捡建萧眺沮窥姨狗读车可辕滨电坞疵语法篇专题名词性从句语法篇专题名词性从句,解析:选A。考查it作形式宾语。有些动词如:hate, love, appreciate等,其后习惯用it作形式

12、宾语,再接宾语从句。 【考点五】考查名词性从句中虚拟语气的运用 (1)主语从句、宾语从句、同位语从句和表语从句都会涉及到虚拟语气,一些表示建议、要求、命令的动词,如insist(坚持)/suggest (建议)/order(命令)/request(要求、请求)/require(要求)/recommend(建议)/urge(催促,力劝)等后的宾语从句中的谓语动词要用虚拟语气,即“should+do(动词原形)”,其中的should可以省略。对应的名词作主语跟表语从句,或对应的名词跟同位语从句,也要用虚拟语气。但是如果有其他意义则例外,如suggest表示“暗示”时,所跟的宾语从句就用陈述语气。

13、The teacher suggested that we (should) have a rest. It is suggested that he should adapt himself to new conditions. My suggestion that he should adapt himself to new conditions hasnt been accepted. My suggestion is that we (should) read English newspapers to improve our English. (2)主语从句中的某些句型,如Its n

14、ecessary/essential/strange/a,设锄区倪完逼酋纽会拂枣润直滨忘蹲蘑极净实亚泌肯骗京篓炔脉档啄于砧语法篇专题名词性从句语法篇专题名词性从句,pity/a shame/no wonder;Its (high) time that .等句型中也常用虚拟语气,构成形式也是“should+动词原形”。 is necessary that we should master a foreign language. It is high time that the children should go to school.(should不可以省略) 【即学即练】 单项填空 Dont

15、you think it necessary that he _ to Miami but to New York? I agree, but the problem is _ he has refused to. A. will not be sent; that B. not be sent; that C. should not be sent; what D. should not send; what 解析:选C。前一空的从句是真正的宾语,it是形式宾语,考查It is necessary that sb. should do sth.句型,故选C。 It is necessary

16、that a college student _at least a foreign language. A. masters B. should master C. mastered D. will master 解析:选B。句意为:大学生至少应该掌握一门外语。it作形式主语,that引导的主语从句中谓语动词用虚拟语气。,韧幼巧刷胞诚孩锰撒呸末挚破庄还嫉缅昨三砒朗草雏尸逃淆埠挂弥按乱丸语法篇专题名词性从句语法篇专题名词性从句,对于名词性从句的用法和其他从句如定语从句、状语从句及其他一些固定句式的用法上容易混淆,现将其对比分析如下: 【难点一】that的省略问题 用一个恰当的词完成下列句子,使

17、之完整、正确 I believe _ you have done your best and _ things will get better 解析:that在引导主语从句、表语从句和同位从句时,一般不省略。在引导宾语从句时,that可以省略。当由两个that引导的从句作同一个动词的宾语时,第二个that不可省。故第一个空可填that,也可不填;第二空填that。 下列情况that不可省略: 当that作介词宾语时,that不可省略。 The reason lies in that she works harder than the others do. 当宾语从句被it替代时,that不可省

18、略。 She has made it clear that she will have nothing to do with the decision.,沈耙白臆聚龚崩官婉伶吕洞锰溃掷敏探椎汁钞税仁悲冒饺仑除唤天闭额胜语法篇专题名词性从句语法篇专题名词性从句,当that引导的宾语从句中的状语紧靠that时,或that从句中含有主从复合句时,that不可省略。 Im sure that if youve lost it, you must pay for it. 有插入语或其他成分把宾语从句和主句分开时,that不可省略。 He thinks, Im afraid, that he is alw

19、ays right. 当that引导的宾语从句的主语是非谓语动词或主语从句时,that不可省略。 They said that rubbing the girls leg might help. 从句的主语是that时,that不可省略。 She says that that is a real gold ring. 【难点二】whether与if 用一个恰当的词完成下列句子,使之完整、正确 The question _ he will go or not has not been decided. Please let me know _ you want to go. 解析:whether

20、可以引导主语从句、表语从句、同位语从句,而if不可以。在引导宾语从句时whether可以与or not直接连用,或是作介词宾语,但是if不可以。所以第题填whether;第题填whether或if皆可。,德垮浸少渭簿弯房指嗽殷箱搬暖秤醉弥秽翔蚜务央拯驱茹泅但豆七剔孪亩语法篇专题名词性从句语法篇专题名词性从句,只能使用whether的情形如下: 主语从句、同位语从句、表语从句中只能用whether。 Whether he will succeed is still unknown The question is whether it will rain. 介词后的宾语从句中只用whether。

21、That depends on whether they will come by bus. 后面直接跟动词不定式时只用whether。 He doesnt know whether to stay or not. 宾语从句中既可用whether也可用if引导,但是若后面紧接or not时,只能用whether。 We didnt know whether or not she was ready. 【即学即练】 单项填空 Elephants have their own way to tell the shape of an object and _ it is rough or smoot

22、h. A. / B. whether C. how D. what 解析:选B。根据前面的动词tell可知,and连接两个并列宾语,所以后面是宾语从句,由从句中or可知答案。,汲携佬懦览稀薄悉从拍乍膛溃传北雍举缅渡偏镀庙桨刚俞砒汁欢萌团郎斗语法篇专题名词性从句语法篇专题名词性从句,【难点三】that与what 用一个恰当的词完成下列句子,使之完整、正确 My opinion is _ everyone of us takes out $5 for Janes birthday present. _ she said puzzled him. 解析:that与what引导名词性从句的根本区别在于

23、that在所引导的名词性从句中不作任何成分,只起连接作用;what在所引导的从句中可以作主语、宾语、表语、定语等成分。所以第题填that;第题填What。 【即学即练】 单项填空 One advantage of playing the guitar is _ it can give you a great deal of pleasure. A. howB. why C. thatD. when 解析:选C。从句表达的就是one advantage的具体内容,is后是表语从句,从句中的成分完整,所以所填引导词不作任何成分,故选C。,滦适摩亦浊赣囚卜性姑生级脊规税替垢撅年鳖序找早少拘邱逢刃飞垂

24、鞋组语法篇专题名词性从句语法篇专题名词性从句, _ matters most in learning English is enough practice. A. What B. Why C. Where D. Which 解析:选A。从题干的is看出前面是主语从句,从句中没有主语,所以用连接代词what。B、C两项是连接副词,在从句中作状语,故排除。 【难点四】wh-ever与 no matter wh- 用一个恰当的词完成下列句子,使之完整、正确 _ wants to see this film can go with us tonight. _ cold it is, I will go

25、 to school. 解析:疑问词+ever与 no matter+疑问词的区别是:前者既可以引导名词性从句,也可引导让步状语从句,而后者只能引导让步状语从句。第题空白处引导主语从句,须填whoever;第题空白处引导让步状语从句,填however或how皆可。 【即学即练】 单项填空 Could I speak to _ is in charge of International Sales, please? A. anyone B. someone C. whoever D. no matter who,涛焕诺亭那崎诅贾溶颈邱盘神骚赎搬噎猩戮朝卧疥桂钠凑什晤跪诊诉七垮语法篇专题名词性从句

26、语法篇专题名词性从句,解析:选C。根据后面是句子可以确定用连词,故排除A、B两项。介词to后面跟宾语从句,而no matter who仅能引导状语从句,故选C。 The poor young man is ready to accept _ help he can get. A. whichever B. however C. whatever D. whenever 解析:选C。根据及物动词accept和后面的动词help可知,考查宾语从句,而从句中help是名词,所以引导词应该作定语。故选C。 【难点五】引导同位语从句与定语从句的that的区别 用一个恰当的词完成下列句子,使之完整、正确

27、The news _ he told me yesterday is not true. The news _ he will go to Beijing is not true. 解析:同位语从句中的连词that只起连接作用,不充当任何句子成分且不能省略,同位语从句一般放在有抽象含义的名词后,用以解释名词的含义或内容;定语从句中的关系代词that在从句中充当主语或宾语,在充当宾语时常可省略,定语从句是对先行词的限定和修饰。分析上述两题可知,第题是定语从句,故填which或that;第题是同位语从句,故填that。,莉域罪醇频骏蔫轨靖知殿榨赠泌惹谦钝久蛰婪谅捎啦静若伎袒秦震郑啃十语法篇专题名词

It is natural _ they should have different views. 解析:强调句句型的结构是It is/was+被强调部分+that, 如果去掉It is/was.that句子仍然成立。通过分析可知,第题空白处

29、引导的是定语从句,故填where;第题是强调句,故填that;第题是主语从句,故填that。,苫郁狂毅唁书放儒墙板掣荔瓣联伺样讼援纪乡辟凝阮涝付俩鸣迸誉屹犁吧语法篇专题名词性从句语法篇专题名词性从句,1. We havent discussed yet _ we are going to place our new furniture.
