think/believe/suppose/expect/imagine,后接特殊疑问词,引导的宾语从句，疑问词要放在句首。,What do you think is going on outside?,I/We(dont)think/believe/suppose/expect/imagine,后接宾语从,句时，反义疑问句要与从句中的主语和谓语保持一致。,I dont suppose he

doubt if/whether our football team will win the match.,I dont doubt that I can defeat him in the contest.,四、同位语从句,在主从复合句中作同位语的从句称为同位语从句同位语从,句一般用,that,，,whether,，,who,，,which,，,what,，,where,，,when,，,why,，,how,等词引导，常放在,fact,，,news,，,idea,，,truth,，,hope,，,problem,，,information,等名词后面，用以说明,该名词的具体内容。,The news that they had won the game soon spread over the,whole school.,五、名词性从句的难点,1.,引导词,that,与,what,的区别,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,等，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，在从句中也不充当任何句子成分，但,that,引导的主语从句放在句首时，不能省略,that,。,What we cant get seems better than what we have.,That a new teacher will come to teach us geography is true.,2.,引导词,if,和,whether,的区别,if,和,whether,引导动词后面的宾语从句时一般可通用，但介词后,的宾语从句、主语从句、表语从句和同位语从句不能用,if,引导。,I dont care if/whether he will come to my party.,Whether she will go home or not is unknown.,The question is whether we can collect enough money.,3.,引导词,who,与,whoever,的区别,whoever,引导名词性从句时，相当于,anyone who,或,those who,，它,既是从句的主语，又是主句的主语。而,who,只作从句的主语，它,引导的从句才是主句的主语。,Whoever has helped to save the drowning girl is worth praising.,Who will be elected president doesnt make much difference to,me.,4.,引导词,what,与,whatever,的区别,whatever,引导名词性从句时，与,what,差不多，只是语气上更强,些，有“任何一切,”,之意。,It is generally considered unwise to give a child whatever he or,she wants.,This is exactly what I want.,5.,同位语从句与定语从句的区别,同位语从句用于解释前面名词的内容，从句本身是一个非常完,整的句子，所以其前的名词在同位语从句中不作任何成分；定,语从句对其前的名词加以限制和修饰，从句本身不够完整，因,此其前的名词在定语从句中通常作主语、宾语或表语等成分。,I made a promise that if anyone set me free I would make him,very rich.,The mother made a promise that pleased all her children.,6.whoever,与,no matter who,；,whatever,与,no matter what,whoever,和,whatever,既可以引导名词性从句，也可引导让步状语,从句；,no matter who,和,no matter what,只引导让步状语从句。,Whatever(,No matter what)you may think,，,Im going ahead,with my plans.,Take whatever you need and leave me alone.,7.,名词性从句的语序,名词性从句一律用陈述语序。,No one will be sure what man will look like in a million years.,没人知道百万年后人会是什么样子。,8.,名词性从句中的语气,(1),在,It is necessary/natural/important/strange.,that,从句中，,从句中的谓语动词用“,should,原形动词”表虚拟语气，且,should,可省略。,It is necessary that the problem should be settled at once.,(2),表示“建议、命令、要求”意义的动词，后接,that,从句时，从句,中的谓语动词要用虚拟语气，即“,should,原形动词”，且,should,可省略。,Bobs doctor suggests that,he(should,)rest for a few days.,(3),表示“建议、要求、命令、想法”意义的名词，后接,that,从句,时，从句中的谓语动词要用虚拟语气：“,should,动词原形”，,should,可以省略。这类名词有：,advice,，,agreement,，,command,，,decision,，,demand,determination,，,order,，,preference,，,proposal,，,request,，,requirement,等。,This is our only request that this(should)be settled as soon as,possible.,同样，如主语是表示“建议、要求、命令、想法”意义的名词，,那么,that,引导的表语从句中也要用虚拟语气。,Her suggestion was that they(should)carry on their conversation,in
