形容词和副词的比较级和最高级

1、一、形容词和副词的概念形容词：是修饰名词（人或事物），表示名 词的性质，特征或属性一种词类。 它在句中作定语、表语和宾语补足语。副词：用来修饰动词、形容词及其他副词的词叫副词。副词在句中多作状语二、形容词和副词的用法 形容词作定语一般放在被修饰的名词之前。如:a new book, two big trees 等。 形容词放在系动词 be , get,turn, become, keep, stay, look, smell,feel, taste, sound,等之后。如:1.l am short.2.She looks fine.3. They tur n gree n. 如果形容词修饰不

2、定代词 somethi ng,anything, everyth ing, no thi ng等时，要放在不定代词后面。如:something interestingnothing new 副词放在所修饰的动词之后、形容词和副词之前。如果前面是行为动词，则后面用副词。如：1.She works hard . （修饰动词）2.I am very busy.（修饰形容词）3. He runs too quickly .（修饰副词）4. We play happily.（修饰动词） 通常在形容词后加-ly变成副词。slow fusual easy heavy real carefiilhappyun

3、gryi 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1.单音节以及少数双音节的词后面直接加-er或-est原级比较级最咼级talltallertallestsmartsmartersmartestshortshortershortest特别提醒：以-y,-er, -ow, le结尾的双音节形容词末尾加 er和est如:healthy, funny, busy, hungry, easy, happy, early, pretty, lazy

4、, heavy, dirty, clever, narrow等。2.以不发音的e结尾只加-r或-st原级比较级最咼级nicen icernicestfinefinerfin estlargelargerlargest3.“以辅音字母+y”结尾的词改y为i，再加-er或-est原级比较级最咼级easyeasiereasiestprettyprettierprettiesthappyhappierhappiestfunnyfunnierfunni estbusybusierbusiest4.以一个元音加一个辅音字母结尾的重读闭音节词，双写后面的辅音字母，再加-er 或-est原级比较级最咼级thi

5、nthinnerthi nn esthothotterhottestbigbiggerbiggest特别提醒：n ew, few, slow, clean等词含有字母组合，且发的是长元音，不用双写。5.大部分双音节词和多音节的词，要在前面加more，most原级比较级最咼级beautifulmore beautifulmost beautifulimporta ntmore importa ntmost importa ntin terest ingmore in terest ingmost in terest ingexpe nsivemore expe nsivemost expe ns

6、ivepopularmore popularmost popular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,如 unhappy-unhappier-unhappiest, untidy-untidier-untidiest6.以形容词+ly构成的副词要在前面加 more, most原级比较级最咼级slowlymore slowlymost slowlyquicklymore quicklymost quicklyan grilymore an grilymost an grilysoftlymore softlymost softlyn oisilymore n oisily

7、most n oisily特别提醒：early -earlier-earliest7.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/known）只能加more或most来表示它们的比较级和最高级。原级比较级最咼级in terest ingmore in terest ingmost in terest ingexcitedmore excitedmost excit ingtiredmore tiredmost tiredbori ngmore bori ngmost bori ng不规则变化原级比较级最咼级good/wellbetterbestbad/badly/ill

8、worseworstmany/muchmoremostlittlelessleastfarfarther/furtherfarthest/furthe stoldolder/elderoldest/eldest特别提醒： further不仅可以指“距离更远”，还可指“程度更深”。记住以下三个词组：further study（进修）further education（继续教育）further information （进一步的信息） elder 仅用于同辈之间的排行，如：elder sister（ 姐姐）elder brother （ 哥） less作为“更少”仅用来修饰不可数名词，修饰可数名词

9、表示“更少”要用 fewer。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。afraid - more afraid, most afraidtired - more tired , most tiredfond - more fond , most fondglad - more glad , most gladbored - more bored , most boredpleased- more pleased , most pleased下列形容词和副词的比较级和最高级有两种

10、形式，即：既可加 -er/-est也可加 more/mostcruel, strict, often, friendly, 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）empty, wrong, perfect, unique, extreme, excellent, favourite, true, right, correct, extremely .形容词副词比较级最高级使用注意事项比较应在同类事物之间进行。误： Your English is better than me.正： Your English is bett

11、er than 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, even 。以下单词也可用来修饰： any, far, still, a lot, yet, rather。My sister is a little taller than me.Their house is much larger than ours.另外，名词短语也可修饰比较级，说明程度I m three years older than 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 is more kinder to s

12、mall animals than I.正： He is much kinder to small animals than I.误： He is more cleverer than his brother.正： He is cleverer than 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： China is larger that any country in Asia.正： China is larger than any other country in Asia.误： John studies h

13、arder than any student in his class.正： John studies harder than any other student in his class.正： John studies harder than any of the other students in his class. 正： John studies harder than anyone else in his class.比较要遵循前后一致的原则，注意前后呼应。The population of Shanghai is larger than that of Beijing.It is

14、easier to make a plan than to carry it out.序数词通常只修饰最高级。Africa is the second largest continent.The Yellow River is the second longest river in China.This is the third most popular song of Michael Jackson.为避免重复，我们通常用 that, those, one, ones 代替前面出现的名词。that 代替可数名词单数和不可数名词， those 代替可数名词复数。 one 既可指人 又可指物，只

15、能代替可数名词。The weather in China is different from that in America.The book on the table is more interesting than that( 或 the one)on the desk.A box made of steel is stronger than one made of wood.误： In winter, the weather of Beijing is colder than it of Shanghai.正： In winter, the weather of Beijing is c

16、older than that of Shanghai. “否定词+比较级”相当于最高级。Wait until we get a satisfactory reply, will you?I couldnt agree more. The idea sounds great to me.Nothing is so easy as this. =Nothing is easier than this. =This isthe easiest thing.比较级前一般不加冠词。但表示两者中较突出者，且比较级后又有名词或出现了 of the two ，这时比较级前一定要加 the 。He is th

17、e taller of the two.Of the two jobs ，he chose the harder.Which is the younger one, Lily or Lucy?试比较：Which is larger, Canada or Australia?Which is the larger country, Canada or Australia?She is taller than her two sisters.She is the taller of the two sisters.不含than的比较级前可加不定冠词修饰，构成“ a/an+比较级+单数可数 名词”表

18、示“一个更的人/物”。Why dont you use a sharper knife?你为什么不用一把更锋利的刀呢？比较级 than 后应用人称代词的主格，但非正式语体中常用宾格。He is taller than I/me.为避免重复，比较级中同样的动词用助动词do, does, did 替代。I spend less time doing homework than John does.She tells more funny jokes than we do.以下内容不是初中教学的重点，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

19、a most important problem. =It is a very important problem.倍数表达法A is three(four, etc.)times the size(height, length etc.)of B.The new building 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, etc.)times as big(high, long, etc.)as B.Asia is four time

20、s as large as Europe.亚洲是欧洲的四倍大 / 亚洲比欧洲大三倍。A is three (four, etc.)times bigger(higher, longer, etc.)than B.Your school is three times bigger than ours.你们的学校比我们的学校大三倍。用 times 表倍数通常用于三倍以上，两倍可以用 twice 或 double.形容词副词比较级最高级重点句型归纳句型一：形容词或副词比较级+than注意事项：该句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 than I

21、 am.The boy does his homework more carefully than 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 expensive than 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

22、就是根据第 一个as前的动词，如果是系动词（如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 lesson is as easy as that one.Lucy talks with old people as politely as her sister.特别提醒：asas之间也可以跟名词，句型如下：as + 形容词 + a/an + 单数名词 +asHe is as kind a person as his father.他和他爸爸一样都是善良的人。 a

23、s + 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Well 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asas的句型: as as o ne can ：尽其所能 He began to run as fast as he could.as as possible ：尽可能Please help us as quickly as possible.as soo

24、n 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 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

25、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 Changjiang River is the longest river in our country.Peter is the tallest of the six students.This picture is the most beautiful among these.句型六： one of + 形容词最高级 +可数名词复数形

26、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 dinosaurs was about one metre long.句型七：比较级 +and +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 getting hotter and hotter.The girl is becoming 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 mistak
