1&2,2,Predicative Clauses(,表语从句,),3,在复合句中用作表语的从句是表语从句,引导表语从句的关联词与引导主语从句的关联词大致一样,表语从句位于连系动词后,有时用,as if,引导。其基本结构为,:,主语,+,系动词,+that,从句。,Thats what we should do.,Thats why I want to see you.,表语从句的用法,4,The reason for my absence was that I was,ill.,be,seem,look,等动词后均可跟表语从,句：,如：,My suggestion is that we should go,shopping.,It seems that it is going to rain.,5,2.as if,because,也可引导表语从句。,如：,It looks as if its going to rain.,It was because I got up late.,3.,在非正式文体中,引导表语从句的,that,可以省略。如,:,The trouble is(that)he is ill.,6,在表语从句中,当,reason,做主语时,引导词只能用,that,不能用,because,。,如,:,他迟到的原因是因为他没有赶上早班车。,The reason why he was late was that he didnt catch the early bus.,Attention,7,That the earth is round is true.,=It is true that the earth is round.,主语从句的用法,一、主语从句在句中作主语,主语从句可以位于句首,但常见的主语从句多放在句末,句首则用形式主语,it,。,8,2.Whether he will come hasnt been,decided.,=It hasnt been decided whether he,will come.,Attention:,连词,that,whether,在从句中不担任句子成,分,只起连接作用,不能省略,(,注：,if,不可用,来引导主语从句,),。,9,二,.,用,it,作形式主语的结构,(1)It is,名词从句,事实是,It is a fact that,非常荣幸,It is an honor that,是常识,It is common knowledge that,10,(2)It is,形容词从句,(,多用,should,),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 that,似乎,11,(4)It is,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,12,三、,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,:,13,It is a pity that you didnt go to see the film.,It doesnt interest me whether you succeed or not.,It is in the morning that the murder took place.,It is John that broke the window.,14,学习主语从句应该注意的几个问题,1),引导词,that,与,what,what,既有引导主语从句的作用,同时又在从句中作句子成分,(,主语、宾语、表语等,),，这时,what,相当于,all that/everything that.,，常译成,“,所,的,(,东西、事情、话等,.)”,；而,that,只起连接作用，本身无实际意义，在从句中也不担当任何句子成分，但,that,引导的主语从句放在句首时，不能省略,that,。,15,例如,:,（,1,）,What,we cant get seems better than,what we have.,（,2,）,That,we should work out a plan to deal,with the serious situation is important.,16,2),引导词,if,和,whether,if,和,whether,引导动词后的宾语从句时一般可通用，但,介词后的宾语从句、主语从句,(,放在句首时,),、表语从句常由,whether,引导。,例如,:,17,Whether she will go home or not is unknown.,It remains to be decided whether/if we shall raise ducks or geese.,18,【2012,陕西卷,】As many five courses are provided,and you are free to choose _ suits you best.,A.,whatever B.whichever,C.whenever D.wherever,【,解析,】,考查名词性从句。所填词引导的从句做动词,choose,的宾语，引导词在从句中做主语，意思是：无论哪件。选,B,。其余选项与句意不符,B,19,【2012,江西卷,】It suddenly occurred to him _ he had left his keys in the office.,A.whether B.where,C.which D.that,解析,it,作形式主语，真正的主语为,that he had left his keys in the office,。且,that,在句中无意义，并不充当任何成分。,D,20,2012,湖南卷,Everyone in the village is very friendly.It doesnt matter _ you have lived there for a short or a long time.,why B.how,C.whether D.when,考查名词性从句引导的用法。根据空后的,or,可知为,whether or,短语。复合句 名词性从句 主语从句 形式主语 引导词,whether,C,21,【2012,全国新课程,】24.It is by no means clear _ the president can do to end the strike.,how B.which,C.that D.what,【,解析,】,此处,it,是形式主语，,what,引导的是主语从句，作真正的主语。,What,作,do,的宾语。句意：总统采取什么行动结束这次罢工一点也不清楚。,D,22,【2012,山东卷,】It doesnt matter _ you pay by cash or credit card in this
