形容詞的最高級(jí)
1. 用法：英語(yǔ)中三者或三者以上相比較，表示“最……” 這樣的最高程度概念時(shí)，要用 “the+最高級(jí)” 的結(jié)構(gòu)表示。這種句式一般帶有表示比較的介詞短語(yǔ)，比如: in our class, of the three 等。
例如: Wang Lin is the tallest in our class.
This theater is the cheapest of the three.
注意使用最高級(jí)時(shí)應(yīng)注意以下幾點(diǎn)：
(1) 表示 “最……之一” 的句式，要用 one of the +形容詞最高級(jí)+復(fù)數(shù)名詞。
例如：Jingjiang Hotel is one of the biggest hotels in our city.
Lisa is one of my best friends.
(2) 當(dāng)最高級(jí)前面有物主代詞或名詞所有格時(shí)，不加定冠詞 the。
例如：Tom is Lucy’s best friend.
Tuesday is her busiest day.
(3) 最高級(jí)前可加序數(shù)詞。
eg.The Yellow River is the second longest river in China.
(4) 形容最高級(jí)修飾作表語(yǔ)或介詞賓語(yǔ)的名詞，代詞時(shí)，被修飾的詞往往省略。
eg.He is the laziest (student) in our class.
(5)形容最高級(jí)用在選擇疑問(wèn)句中，結(jié)構(gòu)為：Who/Which...,A,B or C?
Who is the best English teacher,Mr.Zhang,Miss Li or Miss Wang？
2. 形容詞比較級(jí)和最高級(jí)的構(gòu)成
(1)規(guī)則變化
一般情況下，單音節(jié)或雙音節(jié)的形容詞比較級(jí)直接加-er, 最高級(jí)直接加-est。如：
clever—cleverer—cleverest cheap—cheaper—cheapest
few—fewer—fewest small—smaller—smallest
young—younger—youngest
b. 以-e 結(jié)尾的形容詞，比較級(jí)+ -r,最高級(jí)+ -st。如： large—larger—largest nice—nicer—nicest
cute—cuter—cutest
c. 以輔音字母+y結(jié)尾的形容詞，變y為i +er或+est
busy—busier—busiest heavy—heavier—heaviest
easy—easier—easiest happy—happier—happiest
dirty—dirtier—dirtiest
d. 以重讀閉音節(jié)結(jié)尾，末尾只有一個(gè)輔音字母結(jié) 尾的詞，雙寫(xiě)最后一個(gè)輔音字母，再加+er或 +est。 如：
big—bigger—biggest thin—thinner—thinnest
fat—fatter—fattest hot—hotter—hottest
e. 多音節(jié)和部分雙音節(jié)形容詞，需在原級(jí)前+more 構(gòu)成比較級(jí)，+ most 構(gòu)成最高級(jí)。
important—more important—most important beautiful—more beautiful– most beautiful
difficult—more difficult—most difficult
最高級(jí)規(guī)則變化口訣：
最高級(jí)，很容易，一般詞尾加est。(cheap-the cheapest)
詞尾若有啞音e，直接就加st。(close-the closest)
重讀閉音節(jié)， 單輔音字母要雙寫(xiě)。(big-the biggest)
輔音字母加y，記得把y變?yōu)閕。(friendly-the friendliest)
多音節(jié)，考考你，the most到底加哪里？
(popular-the most popular)
