15、lltallertallest,freshfresher freshest2以字母e結尾的形容詞只加-r（比較級），-st（最高級）：nicenicernicest ,ableablerablest 3以重讀閉音節結尾的詞，詞尾只有一個輔音字母時，應雙寫這個輔音字母，再加-er（比較級），-est （最高級）：“又大又胖又熱又濕又瘦 ” bigbiggerbiggest,fat-fatter-fattest,hot-hotter-hottest,wet-wetter-wettest,thin-thinner-thinnest4以輔音字母+y結尾的雙音節詞，先改y為i，再加-er（比較級），-e

16、st（最高級）：easyeasiereasiest, dry-drier-driest,heavy-heavier-heaviest5部分雙音節詞和多音節詞，在前面加more（比較級），most（最高級）來構成比較級和最高級： easilymore easilymost easily,active more activemost active（二）不規則變化good / wellbetterbest ; bad / illworseworst ; oldolder/elderoldest/eldestmany / muchmoremost ; little/fewlessleast ; far

17、farther/furtherfarthest/furthest3、 形容詞比較等級的用法級別比較程度表達方式和意義例 句備 注原級同等程度肯定形式A+be+as+adj.原級+as+B（表示A和B一樣）Art is as interesting as music.Lucy is as old as Lily.否定形式A+be+not+so/as+adj.原級+as+B(表示A不如/沒有B.)English is not so difficult as science.Mary is not so/as careful as I. 比較級不同程度（用于兩者比較）A+be+adj.比較級+tha

18、n+B(表示A比B更)Jim is older than Lucy.This apple is bigger than that one.表示一方超過另一方的程度或數量時，可在比較級前加表示程度的狀語，如even、alot、abit、alittle、still、much、far、no、not、by far、three years,five times,20%等修飾。I am two years older than Lily.我比莉莉大兩歲。Our school is twice larger than theirs.程度加深比較級+and+比較級（越來越）The + 比較級，the + 比較

19、級（越, 就越）He is growing taller and taller.The more , the better .（越多越好）more and more beautiful 其他用法比較級+than+any other +可數名詞單數（適用于范圍一致時） 比較級+ than+ the other +可數名詞復數He is taller than any other student / the other students in his class. 比較時，不能與自身比較。 王磊比他班的任何和一個學生都高。錯誤：Wang Lei is taller than any student

20、 in his class.正確：Wang Lei is taller than any other student in his class. 比較級+ than+any +可數名詞單數（適用于范圍不一致時）He is taller than any student in my class.表示“比較A和B，那一個較.”Which language is more difficult,English or Chinese?那種語言比較難學，英語還是漢語？“the+比較級+of the two”意為“兩個中比較的.”.如：Mary is the cleverer of the two.瑪麗是這

22、/遠：序數詞后面接最高級。The Yangtze River is the first longest river in China.長江是中國第一長河。I think computer is the second most useful invention.我認為電腦是第二有用的發明。在比較結構中需注意的問題：1.原級：形容詞原級常用so,very,too,enough,quite等詞修飾He often feels very lonely.他常常覺得很寂寞。Those flowers are so beautiful.這些花如此美麗。2. 原級、比較級與最高級之間有時可以轉換，意思不變。如

23、：Tom is not as tall as Jim.=Tom is shorter than Jim.The song is more popular than the other songs.=The song is the most popular one of all the songs.3.在表示比較的句子中，如果比較對象相同，為避免重復，在從句中常用one、ones、the one、that、those等詞代替前面提到的名詞。that指物,one既可指人又可指物。that可代替可數名詞單數和不可數名詞，而one只能代替可數名詞單數。There are not so/as many

24、apples in this basket as those in that basket.這個籃子里的蘋果沒有那個籃子里的(蘋果）多。4.one of +形容詞最高級+名詞復數”意為“最.的.之一”。如：Beijing is one of the largest cities in China.北京是中國最大的城市之一。5.有些形容詞，如 dead, empty, round, sure, woolen 等受本身含義的限制，沒有比較級。6.當形容詞最高級前有物主代詞修飾時，不加定冠詞the，或者形容詞最高級表示“非?！睍r，也不加定冠詞the，有時可加不定冠詞a/an。如：Monday is

25、my busiest day.星期一是我最忙的一天。It is a most interesting story.(=It is a very interesting story.)它是一個很有趣的故事。7.“倍數+as+形容詞原級+as”表示“幾倍于.”。如：Your story is three times as long as mine.你的故事比我的長兩倍。8.a/an+形容詞比較級的用法The pen is expensive .I want a cheaper one.這支鋼筆很貴。我想要個便宜點的。練習：The air in the countryside is _than th
