形容词副词比较级最高级变化形式归纳

1、形容词/副词比较级最高级变化形式归纳大多数形容词和副词有比较级和最高级的变化，即原级、比较级和最高级，用来表示事物的等级差别原级即形容词的原形，比较级和最高级有规则变化和不规则变化两种。规则变化：单音节以及少数双音节的词后面直接加-er , -est原级比较级最高级如：tall-taller-tallest以不发音的e结尾只加-r , -st “以辅音字母+y ”结尾的词改y为i，再加-er, -est女口： easy-easier-easiest pretty-prettier-prettiest以一个元音加一个辅音字母结尾的单音节词（即重读闭音节词），双写结尾的辅音字母er ,-est女口

2、： Thin-th inn er-th inn esthot-hotter-hottest特别提醒：new, few, slow, clean等词含有字母组合，且发的是长元音，不用双写。大部分双音节词和多音节的词（即音标中含有三个或三个以上元音音素的词），要在前面加more , most女口 :beautiful -more beautiful-most beautiful特别提醒：以形容前缀un构成的三音节形容词不适合上述情况，女口：un happy-un happier- un happiest,un tidy-un tidier- un tidiest以形容词+ly构成的副词要在前面加m

3、ore , most女口：Slowly-more slowly-most slowly quickly-more quickly-most quickly特别提醒：early -earlier-earliest由ing 分词和-ed分词演变过来的形容词（包括不规则动词如know f known）只能加 more或most来表示它们的比较级和最高级。in teresti ng-more in teresti ng -most in teresti ngexcited-more excited -most excit ingtired-more tired -most tiredbori ng-m

5、一步的信息 ）fewer 。 less作为“更少”仅用来修饰不可数名词，修饰可数名词表示“更少”要用以下内容不作为初中英语教学内容，仅供拓展之用。少数单音节词前面加more, most构成比较级和最高级，这类形容词一般为表语形容词和由过去分词变成的形容词tired - more tired , most tiredafraid -more afraid, most afraidfond - more fond , most fondglad -more glad , most gladbored - more bored , most bored-er/-est 也可力口 more/most

6、strict,pleased- more pleased , most pleased下列形容词和副词的比较级和最高级有两种形式，即：既可加ofte n, frien dly, clever下列形容词和副词没有比较级和最高（即表示“最高程度”或“绝对状态”的形容词和副词没 有比较级和最高级）如： empty, wrong, perfect, uniq ue, extreme, excelle nt, favourite,true, right, correct, extremely .比较应在同类事物之间进行。误： Your En glish is better tha n me.正： You

7、r En glish is better tha n mine.比较级前可以有一个表示程度的状语，最常见的三大修饰词是：a little, much, eve n以下单词也可用来修饰：any, far, still, a lot, yet, rather。My sister is a little taller tha n me.Their house is much larger tha n ours.另外，名词短语也可修饰比较级，说明程度。I m three years older tha n he.特别提醒：very, quite, too不可修饰比较级。避免重复使用比较级。误：He i

8、s more kin der to small an imals tha n I.正:He is much kin der to small ani mals tha n I.误： He is more cleverer tha n his brother.正: He is cleverer tha n his brother.比较要符合逻辑，在同一范围内比较时，避免将主语含在比较对象中，这时需使用other来排除自身。误： Chi na is larger that any country in Asia.正: Chi na is larger tha n any other country

9、 in Asia.误：Joh nstudiesharder tha n any stude nt in his class.正:Joh nstudiesharder tha n any other stude nt in his class.正:Joh nstudiesharder tha n any of the other stude ntsinhis class.正:Joh nstudiesharder tha n anyone else in his class.比较要遵循前后一致的原则，注意前后呼应。The populati on of Shan ghai is larger tha

11、hose代替可数名词复数。 one既可指人又可指物，只能代替可数名词。The weather in Chi na is differe nt from that in America.The book on the table is more interesting than that( 或 the one)on the desk.

15、重点，仅供拓展之用。形容词 most前面没有the，不表示最高级的含义，只表示“非常”。It is a most importa nt problem.=It is a very importa nt problem.倍数表达法 A is three(four, etcjtimes the size(height, le ngth etcjof B.The new build ing is four times the size(the height)of the old one.这座新楼是那座旧楼的四倍大(高)/这座新楼比那座旧楼大(高)三倍。 A is three(four, etcjti

17、型为比较级的最基本句型。只要看到than，即可确定前面使用比较级。He is taller tha n I am.The boy does his homework more carefully tha n the girl.句型二：less +形容词的原级+ than注意事项：该句型表示“不如、不及”，特别需要注意的是， less 本身就是little的比较级，后面必须 跟形容词 的原级，否定就造成了比较级的重复使用。This computer is less expe nsive tha n that one.句型三：as +形容词或副词的原级 + as注意事项：该句型表示对比的两者程度相

18、当，as之间必须跟形容词或副词的原级，决不能使用比较级。此外，还要确定使用形容词还是副词。确定的依据就是根据第一个as前的动词，如果是系动词(女口 be ,感官动词 look, sou nd, smell, taste, feel 等)，那么就用形容词的原级，如果前面 的动词是一般的实义动词，那么就必须用副词的原级修饰动词。This less on is as easy as that one.Lucy talks with old people as politely as her sister.特别提醒：as, as之间也可以跟名词，句型如下： as +形容词+ a/an + 单数名词 +

19、asHe is as kind a person as his father.他和他爸爸一样都是善良的人。 as + many/much+不可数名词 /可数名词复数 +asI can carry as much paper as you can.你能搬多少纸，我也能。I have as many books as you do.我的书和你的一样多。We ll give you as much help as we can.我们将尽我们所能给你帮助。其它几个关于 as, as的句型： as , as one can:尽其所能He bega n to run as fast as he could

20、. as , as possible :尽可能Please help us as quickly as possible. as soon as , 一, 就,He will call me as soon as he comes here.句型四：not as/so + 形容词或副词的原级 + as注意事项：该句型表示“前者不如后者”，往往可以与句型一和句型二替换。第一个as可以换为so。This classroom is not as bright as yours.I cannot run as fast as you.句型五：the +形容词或副词最高级+ in / of / amo

21、ng +比较范围注意事项：如果这里为副词最高级，前面的the常常省略。介词in和of的用法完全不一样。in表示“在某一范围内”，如： in the classroom , in the world 。of表示“在同类之间”，of后面的词与主语同类，另名词前一般有冠词the。among表示“在（三者或三者以上）之间”，among后接代词或没有修饰语的名词。The Chan gjia ng River is the Ion gest river in our coun try.Peter is the tallest of the six stude nts.This picture is the

22、 most beautiful among these.句型六：one of +形容词最高级 +可数名词复数形式注意事项：one of有三大考点：1.后跟形容词最高级；2.后接可数名词复数形式；3.作主语时主语为one,谓语动词用单数形式。One of the smallest dino saurs was about one metre long.句型七：比较级+a nd +比较级/ more and more +多音节词的原级注意事项：该句型表示“越来越，”，如果该形容词比较级构成形式加er，则用前面的句型；如果该 形容词比较级加more构成，则用后面的句型。It is gett ing

23、hotter and hotter.The girl is beco ming more and more beautiful.句型八：the +比较级+, , the + 比较级+,注意事项：该句型意思为“越,就越,”，表示两种情况同时变化。The more you eat, the fatter you will be.In the test, the more careful you are, the fewer mistakes you will make.句型九：be differe nt from注意事项：该句型没有运用比较级，但也是对两者事物进行比较。注意前后比较需在同类事物中进行。My schoolbag is differe nt fr
