1、新课标人教版课件系列,高中英语必修3-5.6,Unit5 Canada-The True North,Revision：The noun clause,在复合句中起名词作用的从句叫名词从句(Noun Clauses）。名词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。,名词性从句,名词性从句考点,（1）连接词的选用（2）主句与从句时态的呼应（3）名词性从句的语序问题（4）it 作为形式主语或形式宾语的用法（5）同位语从句和定语从句的区别(6)名词性从句的虚拟语气问题

2、,连接词的选用,(1)、that和what的区别that 引导名词性从句时，在主从句中不充当任何句子成分，也没有任何含义，只起连接作用；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.1._ he wants is a book.2._ he wants to go there is obvious.,What,That,(2).if 和whether 的选用,不能使用if 的情况：a.放在句首的主语从句b.表语从句c.同位语从句e.介词后的宾语从句f.whether to do 做动词宾语不能用if to do.g.whether or not 连在一起引导宾语从句时不用if.,

3、（3）疑问词+ever和no matter+疑问词的区别疑问词+ever可引导名词性从句，在主从句中要充 当一定的部分。如：Whoever breaks the rule must be punished.You can choose whatever you like in the shop.疑问词+ever还可引导让步状语从句。如：Whoever breaks the rule,he must be punished,Whatever you do,you must do it well.no matter+疑问词只能引导让步状语从句。如：No matter what you do,you

4、 must do it well.No matter who breaks the rule,he must be punished.,（4）其它连接代词和副词的选用,主要根据名词性从句中的具体意义,正确的选择who、which、when、where、why、how 等连接词，这些连接词既具有疑问含义，又起连接作用，同时在从句中充当各种成分。,我们何时举行运动会还没有决定。_ we shall hold our sports meeting is not decided.这就是我忘记眼镜的地方。This is _ I left my glasses.,When,where,名词性从句中的时态呼

5、应,（1）宾语从句中主句和从句的时态保持一致.,a.如果主句时态是现在时或将来时,从句谓语 可根据句意需要而选用任一种时态.He believes _.Please tell me _.,his dream will come true some day,what you were doing at this time yesterday,b.如果主句谓语是过去时,从句谓语动词一般用过去的 某种时态,但从句表达的是客观事实、真理、自然规 律等时，从句谓语通常用一般现在时。He told me _.He told me _.The teacher told us _,he was prepari

6、ng for the examination,He had been away from his hometown for ten years,light travels in a straight line.,（2）主语从句作主语相当于单数第三人称作主语，谓语动词用单数，如果由and 连接两个或两个以上的主语从句作主语时，谓语动词用复数；由两个或多个连接词引导一个主语从句，谓语动词用单数。如：When the meeting will begin has not been decided yet.When they will start and where they go have not

7、been decided yet.When and where the meeting will begin has not been decided.,疑问词引导的名词性从句也要求使用陈述句 语序，不能用一般疑问语序。,他是怎么成功的仍然是个谜。How was he successful is still a puzzle.()How he was successful is still a puzzle.(),你能告诉我他住在什么地方吗？Could you tell me where he lives?()Could you tell me where does he live?(),F,

8、T,T,F,名词性从句的语序,在名词性从句中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,不能用 this和 that来代替 it.如:_is a fact that English is being accepted as an international language.A.There B.This C.That D.ItI hate _when people talk with their mouths full.A.it B.that C.these D.them,D,A,it 作为形式主语或形式宾语的用法,1.定语从句是先行词的修饰

9、语，它不涉及先行词的具体内容。定语从句中that不但起连接作用，而且在定语从句中充当一个句子成分，充当从句的宾语成分时可省略。,2.同位语从句对中 心词的内容作进一步的解释和说明，表明中心词的具体内容。引导同位语从句的that在同位语从句中不做任何成分,只起连接作用,无具体含义,且不可省略.,同位语从句与定语从句中that的区别。同位语从句中的连词that只起连接作用，在从句中不担当任何句子成分；定语从句中的关系代词that在句中做宾语或主语，宾语与先行词有修饰关系。,同位语从句和定语从句的区别,1.We expressed the hope that they had expressed.2

10、.We expressed the hope that they would come to China again.,1.The information has been announced that more middle school graduates will be admitted into university.2.The information that he revealed at the meeting is of great value.,Attributive or Appositive,AT,AP,AP,AT,在名词性从句中,主语,表语,宾语,同位语四种从句都可用到

11、虚拟语气.主语从句中在“It+be+necessary等形容词+从句”和It+be+suggested等(表示命令,要求,建议等动词的过去分词)+从句结构中,一般用虚拟语气.这时从句中的谓语动词由“should+动词原形”构成.宾语从句中某些表示“愿望、请求、建议、命令、决心”等意义的动词后也用“（should)+动词原形”来构成谓语，表示虚拟。常见词如下：advice,ask,decide,command,demand,insist,order,propose,request,require,recommend,suggest,urge等。,名词性从句中的虚拟语气问题,表语从句或同位语从句在

12、某些表示“建议、请求、命令”等意义的名词后同样需用“(should)+动词原形”来构成谓语。这类名词有：advice,desire,decision,idea,order,plan,proposal,rec-ommendation,request,suggestion等。如：,My suggestion is that we(should)read English newspapers to improve our English.The teacher suggested that we(should)have a rest.It is necessary that he(should)co
