12、的宾语从句要用虚拟语气“should+动词原形”结构,should 可以省略。这类动词有:advise,arrange,command,demand,desire,insist,order,propose,require,request,suggest等。如：I suggested that he(should)study harder.vI know he lives here .vI know he lived here ten years ago.vI have heard that he will come tomorrow.三、时态1.主句用现在时或将来时，从句可用任何时态，根据实际

13、情况而定。2.如果主句是过去的时态（一般过去时，过去进行时），从句的时态一定要用相应的过去的某种时态（一般过去时，过去进行时，过去将来时，过去完成时）vI knew who lived here.vI saw she was talking with her mother.vHe asked whether his father would come back tomorrow.vHe said that he had seen it.The teacher told me she was born in 1960.I heard that he went to Paris last nigh

20、见的系动词，可以有多种时态。2.表示结果:become成为，当3.表示状况，样子等：seem,appear,look 看起来，看上去4.表示变化：go,come，get,turn,fall,run,grow 变得，变成5.感官系动词表示感觉：feel摸起来，感觉；smell闻起来；taste尝起来；sound听起来,；look看起来6.表示状态：prove证明是；turn out；remain保持，仍然；stay保持，停留；keep保持；stand位于；lie位于；rest停留，剩余1.名词，代词，数词用作表语：He finally became a successful pianist.My

25、/why/how 3.表语从句的连接词表语从句两大要素：除that外的所有引导词都有自己的意义。除that,whether 外的所有引导词都必须在从句中充当相应的成分。1.that 引导的表语从句that 仅起连接作用，无意义，在句中不作任何成分。这种从句往往是对主句主语的内容起进一步解释的作用。e.g.The chance is that one smoker in four will die from smoking.2.whether 引导的表语从句连接词whether起连接作用，意为“是否、究竟、到底”（注意：if不能引导表语从句)在句中也不作任何成分。e.g.The question

26、 is whether what man will turn up in time.3.what,which,who,whom,whose引导的表语从句连接代词what,which,who,whom,whose除在句子中起连接作用外，还可在从句中从当主语、表语、定语，且各有各的词义。e.g.Tom is no longer what he used to be.The question is which of us should come first.The problem is who is really fit for the hard job.The important thing is

27、 whose name should be put on the top of the list.4.where,when,why,how引导的表语从句连接副词where,when,why,how除在句中起连接作用外，在从句中还充当时间、地点、方式、原因状语，本身具有词义。e.g.Thats where I cant agree with you.This is why Sara was late for the meeting.This is how they overcome the difficulties.My strongest memory is when I attended a

28、n American wedding.5.其他连词as if,because,as though 引导的表语从句because引导表语从句通常只用于“This/That/It is because”结构中。as if/though引导的表语从句常置于连系动词look,seem,sound,be,become等后面，常用虚拟语气，表示不存在的动作或状态。e.g.It sounds as if/though somebody was knocking at the door.My anger is because you havent written to me for a long time.6

29、.使用虚拟语气的表语从句在表示建议、劝告、命令含义的名词后的表语从句，谓语动词需用虚拟语气should+动词原形 表示，should可省略。常见的词有：advice,suggestion,order,proposal,plan等。My suggestion is that we(should)start early tomorrow.策划：学生双语报45表语从句中应该注意：（1）当the reason 或why引导主语从句时，常用that(不用because)引导表语从句。Why we should not play on the ground is thatwe are having cla

30、ss.The reason why we should not play on the ground is that we are having class.（2)Whether 引导表语从句,if 不能引导表语从句试区分以下句子Is this museum what you visited?Is this the museum that you visited?Is this museum the one that you visited?注意：这种句子考试时一定要记住这句话：名词前（尤其是单数可数名词前）一定要有限定词。然后把句子变换成陈述句，接着判断句子是属于哪种从句再完成。(表从)(定
