1、 形容詞比較級最高級變化形式歸納一般單音節詞后面直接加-er , -est如：tall; cheap; short; quick; thick; light; cool; warm; quiet; wild; calm 以不發音的e結尾只加-r，-st 如：late-later-latest；large-larger-largest“以輔音字母+y”結尾的詞改y為i，再加-er, -est 如：easy-easier-easiest; pretty-prettier-prettiest; heavy-heavier-heaviest以一個元音加一個輔音字母結尾的單音節詞（即重讀閉音節詞），雙寫

2、結尾的輔音字母再加er，-est 如：thin-thinner-thinnest;hot-hotter-hottest; big-bigger-biggest 特別提醒：new, few, slow, clean等詞含有字母組合，且發的是長元音，不用雙寫。 大部分雙音節詞和多音節的詞(即音標中含有三個或三個以上元音音素的詞)，要在前面加 more，most 如:beautiful-more beautiful-most beautiful; serious-more serious-the most serious 特別提醒：以形容前綴un構成的三音節形容詞不適合上述情況，如：unh

3、appy-unhappier-unhappiest, untidy-untidier-untidiest 特別提醒：early -earlier-earliest 由ing分詞和-ed分詞演變過來的形容詞(包括不規則動詞如knowknown)只能加more或most來表示它們的比較級和最高級。 interesting-more interesting-most interesting；boring-more boring -most boring; excited-more excited-most excited; tired-more tired -

4、most tired 少數單音節詞前面加 more, most 構成比較級和最高級，這類形容詞一般為表語形容詞和由過去分詞變成的形容詞 afraid -more afraid-most afraid; fond- more fond-most fond; glad -more glad-most glad bored - more bored- most bored; pleased- more pleased- most pleased 下列形容詞的比較級和最高級有兩種形式: 既可加-er/-est也可加more/most   &#

5、160;  strict, friendly, clever, cruel 下列形容詞沒有比較級和最高（即表示“最高程度”或“絕對狀態”的形容詞和副詞沒有比較級和最高級）如：empty, wrong, perfect, unique, extreme, excellent, favourite, true, right, correct, 不規則變化 good/well-better-best bad/badly/ill-worse-worst many/much-more-most little-less-leastfar-farther/further -fa

6、rthest/furthest old-older/elder-oldest/eldest特別提醒：further不僅可以指“距離更遠”，還可指“程度更深”。如：further study(進修)；further education(繼續教育)；further information (進一步的信息)elder僅用于同輩之間的排行，如: elder sister(姐姐) elder brother (哥哥)less作為“更少”僅用來修飾不可數名詞，修飾可數名詞表示“更少”要用fewer。副詞比較級最高級變化形式歸納1. 一般副詞 (形容詞與副詞同形)hard harder hardest fa

7、st faster fastest late later latest early earlier earliest 2. 特殊副詞 （不規則變形）well better best much more most badly worse worst little less least 3. 開放類副詞 開放類副詞即以形容詞加后綴-ly結尾的副詞應在副詞原形前加more或most。如： quickly more quickly most quickly quietly more quietly most quietly slowlymore slowlymost slowly形容詞比較級和最高級的

8、用法1. 三者或三者以上相比,最高,用“ the +最高級” 的結構表示。后跟表范圍的介詞短語: in our class , of them five, of the three, of all , in ChinaEg : Zhanghua is the tallest . (三人中) (注意：John is the taller of the two boys. (比較級前定冠詞the不可省）)2. 表示在三者及以上的人或物中進行選擇時,Who / Which + be +最高級, A, B, or C ? Eg: Who is the tallest, Tom, Jack, or Da

9、vid? Tom, Jack與David三個人中誰最高？3. 表示, “最.之一”的句式,用one of the + 形容詞最高級+ 復數名詞 a. Honghong is one of the best students in our class.b. SuZhou is one of the most beautiful cities in China.4.當最高級前有物主代詞或者名詞所有格，省略the a. Monday is my busiest day. 星期一是我最忙的一天. b. Jack is Jims best friend. Jack 是Jim最好的朋友.5. 最高級前可加

10、序數詞. The Yellow River is the second longest river in China.6. 最高級修飾作表語的名詞,代詞時,被修飾的詞往往省略. eg: He is the tallest (boy ) in his class. 比較應在同類事物之間進行。誤：Your English is better than me.正：Your English is better than mine. 比較級前可以有一個表示程度的狀語，最常見的三大修飾詞是：a little, much, even。以下單詞也可用來修飾：any, far, still, a lo

11、t, yet, rather。My sister is a little taller than me.Their house is much larger than ours.另外，名詞短語也可修飾比較級，說明程度。Im three years older than he.特別提醒：very, quite, too不可修飾比較級。 避免重復使用比較級。誤：He is more kinder to small animals than I.正：He is much kinder to small animals than I.誤：He is more cleverer than his bro

12、ther.正：He is cleverer than his brother. 比較要符合邏輯，在同一范圍內比較時，避免將主語含在比較對象中，這時需使用other來排除自身。誤：China is larger that any country in Asia.正：China is larger than any other country in Asia.誤：John studies harder than any student in his class.正：John studies harder than any other student in his class.正：John

13、 studies harder than any of the other students in his class.正：John studies harder than anyone else in his class. 比較要遵循前后一致的原則，注意前后呼應。The population of Shanghai is larger than that of Beijing.It is easier to make a plan than to carry it out.  序數詞通常只修飾最高級。Africa is the second largest contine

14、nt.The Yellow River is the second longest river in China.This is the third most popular song of Michael Jackson.為避免重復，我們通常用that, those, one, ones代替前面出現的名詞。that代替可數名詞單數和不可數名詞，those代替可數名詞復數。one既可指人又可指物，只能代替可數名詞。The weather in China is different from that in America.The book on the table is more intere

15、sting than that(或the one)on the desk.A box made of steel is stronger than one made of wood.誤：In winter, the weather of Beijing is colder than it of Shanghai.正：In winter, the weather of Beijing is colder than that of Shanghai. “否定詞 + 比較級”相當于最高級。-Wait until we get a satisfactory reply, will you?-

16、I couldn't agree more. The idea sounds great to me.Nothing is so easy as this. =Nothing is easier than this. =This is the easiest thing.比較級前一般不加冠詞。但表示兩者中較突出者，且比較級后又有名詞或出現了of the two，這時比較級前一定要加the。He is the taller of the two.Of the two jobs，he chose the harder.Which is the younger one, Lily or Lu

17、cy?試比較：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 的比較級前可加不定冠詞修飾，構成“a/an+比較級+單數可數名詞”表示“一個更的人/物”。Why dont you use a sharper knife? 你為什么不用一把更鋒利的刀呢？比較級than 后應用人稱代詞的主格，但非正式語體中常用賓格。He

18、is taller than I/me.為避免重復，比較級中同樣的動詞用助動詞do, does, did替代。I spend less time doing homework than John does.She tells more funny jokes than we do. 以下內容不是初中教學的重點，僅供拓展之用。形容詞most前面沒有the，不表示最高級的含義，只表示“非常”。It is a most important problem.=It is a very important problem.倍數表達法 A is three(four, etc.)times th

19、e size(height, length etc.)of B.   The new building is four times the size(the height)of the old one.   這座新樓是那座舊樓的四倍大（高）/這座新樓比那座舊樓大（高）三倍。   A is three(four, etc.)times as big(high, long, etc.)as B.    Asia is four times as large as Eur

20、ope. 亞洲是歐洲的四倍大/亞洲比歐洲大三倍。   A is three (four, etc.)times bigger(higher, longer, etc.)than B.     Your school is three times bigger than ours.你們的學校比我們的學校大三倍。用times表倍數通常用于三倍以上，兩倍可以用twice或double. 形容詞副詞比較級最高級重點句型歸納 句型一：形容詞或副詞比較級+than注意事項：該句型為比較級的最基本句型。只要看

21、到than，即可確定前面使用比較級。He is taller than I am.The boy does his homework more carefully than the girl. 句型二：less + 形容詞的原級 + than注意事項：該句型表示“不如、不及”，特別需要注意的是，less本身就是little的比較級，后面必須跟形容詞的原級，否定就造成了比較級的重復使用。This computer is less expensive than that one. 句型三：as +形容詞或副詞的原級+ as注意事項：該句型表示對比的兩者程度相當，as之間必須跟形

22、容詞或副詞的原級，決不能使用比較級。此外，還要確定使用形容詞還是副詞。確定的依據就是根據第一個as前的動詞，如果是系動詞（如be，感官動詞look, sound, smell, taste, feel等），那么就用形容詞的原級，如果前面的動詞是一般的實義動詞，那么就必須用副詞的原級修飾動詞。This lesson is as easy as that one.Lucy talks with old people as politely as her sister. 特別提醒：asas之間也可以跟名詞，句型如下： as +形容詞+ a/an +單數名詞+as  &#

23、160; He is as kind a person as his father. 他和他爸爸一樣都是善良的人。 as + many/much+不可數名詞/可數名詞復數+as    I can carry as much paper as you can. 你能搬多少紙，我也能。    I have as many books as you do. 我的書和你的一樣多。    Well give you as much help as we can. 我們將盡我們所能給你幫助。 其它幾個關于asas的句

24、型： as as one can：盡其所能  He began to run as fast as he could. as as possible：盡可能     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 +形容詞或副詞的原級+ as注意事項：該句型表示“前者不如后者”，往往可以與句型一和句型二替換。第一個a

25、s可以換為so。This classroom is not as bright as yours.I cannot run as fast as you.句型五：the +形容詞或副詞最高級+ in / of / among +比較范圍注意事項：如果這里為副詞最高級，前面的the常常省略。介詞in和of的用法完全不一樣。in表示“在某一范圍內”，如：in the classroom，in the world。of表示“在同類之間”，of后面的詞與主語同類，另名詞前一般有冠詞the。among表示“在（三者或三者以上）之間”，among后接代詞或沒有修飾語的名詞。The Changjiang R

26、iver 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 + 形容詞最高級+可數名詞復數形式注意事項：one of有三大考點：1. 后跟形容詞最高級；2. 后接可數名詞復數形式；3. 作主語時主語為one，謂語動詞用單數形式。One of the smallest dinosaurs was about one metre long. 句型七：比較級+a

27、nd +比較級 / more and more +多音節詞的原級注意事項：該句型表示“越來越”，如果該形容詞比較級構成形式加er，則用前面的句型；如果該形容詞比較級加more構成，則用后面的句型。It is getting hotter and hotter.The girl is becoming more and more beautiful. 句型八：the +比較級+, the +比較級+注意事項：該句型意思為“越就越”，表示兩種情況同時變化。The more you eat, the fatter you will be.In the test, the more care
