形容词和副词的比较级和最高级讲解与练习
一、变化规则
①一般的比较级和最高级在形容词或副词后加-er或-est,
如:
small---smaller---smallest
②以不发音-e结尾的形容词或副词直接加–r或–st,
如:
large---largest---largest
③重读闭音节词尾是一个辅音字母的,需双写该辅音字母,再加-er或-est。
④以辅音字母加y结尾的形容词和副词,把“y”变“i”,再加–er或-est.
busy---busier---busiest
happy---happier---happiest
一些双音节及多音节形容词或副词前要加more和most,如:
slowly---moreslowly---mostslowly
difficult---moredifficult---mostdifficult
beautiful---morebeautiful---mostbeautiful
还有一些不规则的变化:
good/well---better---best
many/much---more---most
bad/ill/badly---worse---worst
little---less---least
far---farther/further---farthest/furthest
二、形容词和副词的等比句型
①as…as…和……一样
I’mastallasyou.
②notas(so)…as不和……一样(在否定句中常用so来代替as)如,
Ican’trunsofastasyou.
另外as…aspossible为固定结构,如,assoonaspossible,asquicklyaspossible等。
在以上两个句型中形容词或副词一定要用原级。
练习:
她吃的不如她爸爸多。
____________________________
我的房间不如你的干净。
______________________________
你必须跟他一样认真。
________________________________
▲as…as前还可以加倍数,如:
Theroomistwotimesaslargeasthatone.
三、比较级(两者之间)
(1)两者相比:
Whichis+比较级,AorB?
如:
Whichisbigger,thesunorthemoon?
(2)比较级+than.如:
MikeistallerthanJohn.
(3)有"ofthetwo”,用the+比较级.如:
Lucyisthemorecarefulofthetwo.
(4)比较级前可用much/alot//far/alittle/abit/even等修饰.如:
Thisbookismuchmoreinterestingthanthatone.
TheblouseIboughtyesterdayisalittlelessexpensive.
Toplaybasketballisfarmoreenjoyabletotheboy.
(5)比较级+and+比较级,表“越来越……”
Itbecomeswarmerandwarmer.
(6)“the+比较级,the+比较级”,表“越……,越……”
Thehigheryoustand,thefartheryouwillsee.
练习:
1.你吃的越多,就会越胖._______________________
2.Mikelooks_____thanPaul,buttheyareofthesameage.
A.youngestB.theyoungestC.youngerD.veryyounger
四、最高级(三者或三者以上)
1)三者或三者以上相比较用“the+最高级+名词+范围(of/all+---)”。
例如:
Thisisthecleanestplaceofthecity.这是这个城市最清洁的地方。
HuYunisthefastestofallthegirlsinourclass.胡云是我们女生中跑得最快的
2)表示“最……之一”,用“oneofthe+形容词最高级+复数名词”。
例如:
TheGreatWallofChinaisoneofthegreatestbuildingsintheworld.中国的长城是世界上最伟大的建筑之一。
ThisisoneofthemostinterestingbooksthatI'veeverread.这是我读过的最有趣的书之一。
注意:
形容词的最高级前面必须加定冠词the,但当形容词最高级前面有物主代词修饰时,则不加the。
副词前面的the可以省略。
例如:
(正)Thisismybestfriend.
(误)Thisismythe(themy)bestfriend.
(正)Todayisthehappiestdayofmylife.
(误)Todayishappiestdayofmylife.
