is necessary(important,natural,strange,etc.)that,It is suggested(requested,proposed,desired,etc.)that,第8页,主语从句中“主谓一致”：,1.主语从句通常被看作一个整体,主句谓语动词用单数形式.,That they will come _certain.,2.What

are good in nothing.,第12页,注意：在,demand，order，suggest，decide，insist,desire,request,command,doubt,等表示,要求、命令、提议、决定,等意义动词后，宾语从句惯用“（should）+动词原形”。,I insist that she(should)do her work alone.我坚持要她自己工作。,The commander ordered that troops(should)set off at once.司令员命令部队马上出发。,第13页,2.用whether或if引导宾语从句，其主语和谓语次序也不能颠倒，仍保持陈说句语序。另外，whether与if 在作“是否”意思讲时在以下情况下普通只能用whether，不用if：,a.引导,主语从句,并在,句首,时；b.引导,表语从句,时；c.引导从句作,介词宾语,时；d.从句后有“,or not,”时；e.后接,动词,不定式,时。,第14页,Whether there is life on the moon is an interesting question.,The question is

job.,(,已经完成了工作),时态呼应,否定转移,我认为他不会来这里.,I think he wont come here.(),I dont think he will come here.(),had finished,注意,第16页,4.注意宾语从句中时态呼应，当主句动词是现在时，从句依据本身句子情况，而使用不一样时态。比如：,I know(that)he studies English every day.,I know(that)he studied English last term.,I know(that)he will study English next year.,I know(that)he has studied English since 1998.,第17页,当主句动词是过去时态（could,would除外），从句则要用对应过去时态，如普通过去时，过去进行时，过去未来时等；当从句表示是客观真理，科学原理，自然现象，则从句仍用现在时态。比如：,The teacher told us that Tom had left us for America,第18页,宾语从句中用it作形式宾语,We think it,our duty,that we should help others.,注意：假如主句中有形容词或名词作宾语补足语时，普通用it来作形式宾语，把从句放在宾补后面。,我发觉他两天之内完成工作是不可能.,I find it,impossible,that he can finish the work in two days.,第19页,Exercises:“it”作形式主语或形式宾语：,1.I hate _

problem is_,This is_.,It looks_.,that,we have lost touch with him,.,how,Henry solved the problem.,as if it is going to rain.,第21页,需要注意，当主语是reason时，表语从句要用that引导而不是because。,The reason why he was late was that he missed the train by one minute this morning.,【注意】whether 可引导表语从句，但与之同义if却通常不用于引导表语从句。,第22页,在句中起同位语作用.普通放在名词,fact,news,idea,promise,thought,suggestion,belief,truth,等之后,用以说明或解释前面名词.引导词有连词,that(不能省),；少数情况下也可用连接副词等.,1.The thought,that we might succeed,excited
