Construction),英语中比较结构最主要有三种：,asas,结构,morethan,结构,the most,结构,第4页,1.asas,结构,基本模式：,as+adj/adv(,原级）,+as,否定形式：,1)not as/so+adj/adv(,原级）,+as,2),也可用,lessthan,e.g John is,as,bright,as,Bob.,(,否定）,John is,not as,bright,as,Bob.,John is,less,bright,than,Bob.,第5页,使用方法：,主语不一样，比较项目相同。,This parcel is as heavy as that one.,2.,主语相同，比较项目不一样。,The girl was as brilliant as she was beautiful.,这姑娘既漂亮又聪明,。,3.,主语和比较项目都不一样。,The swimming pool isnt,twice as wide as that one is long,.,（倍数,+as+adj/adv+as.),第6页,另一个模式：,as much/many+n+as,否定形式：,not as/so much/many+n+as,1)He took as much butter as he need.,He didnt take as/so much butter as he needed.,2)She has written as many essays as her brother(does).,She hasnt written as many essays as her brother(does).,第7页,变体形式：,as+adj(,原级）,+,名词词组,+as,(,注意以下句子语序）,1.George is,as efficient a,worker,as,Jack.,(,名词意义受到强调）,or George is a worker(who is),as,efficient,as Jack,.(,形容词意义受到强调）,2.I dont want,as expensive a car as,this.,第8页,2.more than,结构,1),用于在两个人或物之间作同首先比较。,The concert,was,moreenjoyable,than,lecture,.,2),用于同一个人或物本身作不一样方面比较。,The present crisis is much,more,a political,than,an economic crisis.,当前危机,与其说,是,经济,危机，,不如说,是,政治,危机。,此使用方法也可用于,lessthan,结构，但得出,相反,含义。,The present crisis is much,less,a political,than,an economic crisis.,当前危机,与其说,是,政治,危机，,不如说,是,经济,危机。,第9页,3.,（,the,）,+adj/adv,最高级,+,比较范围,比较级形式表示最高级意义时，比较对象范围应用：,any other+,单数名词,the other+,复数名词,the others,anyone/anything else,上述词是用来将比较级结构转变成最高级意义关键词语，切不可遗漏，不然会造成逻辑混乱错误。,第10页,补充说明,1,not soas¬ so much as,London isnt so big as Tokyo.,伦敦没有东京大。,It wasnt so much his appearance I liked as his personality,.,(,与其说,我喜欢他外表，,不如说,我喜欢他为人。）,前一例相当于普通比较结构，后一例相当于,less,than,含义。,not so much,as,是一个专四常考结构,。,第11页,真题举例：,It is,not,so,much,the language,as,the background that makes the book difficult to understand.(99,45)(07.57)【,注：同一个句子专四考了两次，这说明了重复看往年题主要性,】,That trumpet player was certainly loud.But I was,nt,bothered,by,his loudness,so much as,by,his lack of talent.(04,41),第12页,2.not more/-er than,与,no more/-er than,John is,not,better than Tom.(,否定前者，必定后者,),John is,no,better than Tom.(,对前后者都否定）,真题举例：,Over population pose a terrible threat to human race.Yet it is probably,not more,a threat,than,environmental destruction.(07.62),第13页,3.no more than(=notany more than),二者一样都不,A whale is,no more,a fish,than,a horse is.,鲸不是鱼，如同马不是鱼一样。,Fat can,not,change into muscle,any more than,muscle changes into fat.(99.44),脂肪不能变成肌肉，就如同肌肉不能变成脂肪一样。,第14页,4.the morethe more,与,more and more,the more.the more,表示,两个过程中同时递增,，是主从结构。,more and more,只,表示一个过程不停增加。,如,the wilder the range of our life and the more various the contacts we have,the wilder and suppler must be our command over a rang of English styles.,第15页,5.“of a+n”,比较级,“,of a+n”,相当于一个形容词，表示含有后面那个名词性质；若该名词为,可数名词，,名词之前要加,不定冠词,。它比较级也要用,more,来修饰。如,He is more of a doctor.,他更像个医生。,该结构也能够用于同级比较结构中。如,He is as of an athlete as she.,他和她一样具备运动员素质。,第16页,二,虚拟语气,1.,主从句谓语动词时态,(1),掌握主从句谓语动词规范搭配,:,主 句,从 句,与现在事实相反,would/,情态动词过去式,+do,were(,不分人称,)/did,与过去事实相反,would/,情态动词过去式,+have done,had done,与未来事实相反,would/,情态动词过去式,+do,should do/were
