八年级形容词副词比较级专练

形容词和副词一般有三个等级,即原级、比较级和最高等.一比较级表示二者的比较时用比较级,往常用“形容词/副词比较级+than”的构造①在含有连词than的比较级中,前后的比较对象一定是同一范围,即同类事物之间的比较.②在比较级前面使用much,abit,alittle,.far,alot，still,even等2．“比较级+and+比较级”或“moreandmore+原级”表示“愈来愈3．在含有or的选择疑问句中,假如有二者供选择,前面的形容词要用比较级形式.如：Whoistaller,TimorTom谁更高,Tim仍是Tom“the+比较级,the+比较级”,表示“越越”.Themoremoneyyoumake,themoreyouspend.表示倍数的比较级用法：①.Aistimesthesize/height/length/widthofB.如：Thenewbuildingisthreetimestheheightoftheoldone.②.Aistimesasbig/high/long/wide/largeasB.如：AsiaisfourtimesaslargeasEurope.③.Aistimeslarger/higher/longer/widerthanB.如：Ourschoolistwicebiggerthanyours.6.当比较的两方属于同一范围内时候,用other或许else清除自己,由于自己不可以和自己比较.比如：ShanghaiisbiggerthananyothercityinChina.上海比中国其余的城市大.假如比较的两方不属于同一范围内时候,则不存在和自己比较的状况,因此能够不用other或许else.比如：ShanghaiisbiggerthananycityinHeilongjiang.上海比黑龙江的任何城市都大.二最高等1.形容词、副词的最高等形式主要用来表示三者或三者以上人或事物的比较,表示“最”的意思.句子中有表示范围的词或短语.如：ofthethree,inourclass等等..”在含有or的选择疑问句中,假如有三者供选择,前面的形容词要用最高等形式.ofthe+最高等+复数名词”表示“是最之一者+序数词+最高等+名词单数三、原级的用法：一般来说,表示二者同样或不一样样程度时用原级,往常用“as+形容词/副词原级+as...”或“notas（so）+形容词/副词原级+as...”的构造.只好修饰原级的词，very，quite，so，too。比如：Heistootiredtowalkon.他太累了以致于不可以再持续走了。MybrotherrunssofastthatIcan‘tfollowhim.我弟弟跑得那么快以致于我跟不上他。2.原级常用的句型构造“甲+实意动词+(倍数)+as+副词原级+as+乙”表示“甲和乙程度同样”或“甲是乙的几倍”。比如：TomrunsasfastasMike.汤姆和迈克跑得同样快。TomrunstwiceasfastasMike.汤姆跑得速度是迈克的二倍。“甲+助动词+not+动词原形+as/so+副词原级+as+乙”甲不如乙比如：Hedoesn’twalkasslowlyasyou.他走路不像你那样慢A部分用适合形式填空：1.Bobis_________(young)thanFredbut___________(tall)thanFred.
