6、(A)、构成1. 构成的不规则变化:eg. good / well better bad / badly worse many / much more little less far farther / further 2. 构成的规则变化:1) 单音节词和少数双音节词 一般在词尾后加-er 或-est. 如：cold colder nice nicer 2) 重读闭音节词末尾只有一个辅音字母时, 先双写这个辅音字母, 再加-er或-est。如: big bigger thin thinner 3) 以“辅音字母+ y”结尾的双音节词，先改y为i, 再加-er或-est。如： easy eas

7、ier happy happier 4) 多音节词和部分双音节词在词前加more或most。如：delicious more delicious interesing more interesting 比较级规则变化口诀：比较级，要变化，一般词尾加er。(long-longer)词尾若有哑音e, 直接加r就可以。(nice-nicer)重读闭音节， 单辅音字母要双写。(hot-hotter)辅音字母若加y, 记得把y变为i。(happy-happier) (B)、用法1.比较级表示两者 (人或事物) 的比较。eg. I am taller than Tom.2.在形容词比较级前还可用much,

8、 even, still, a little来修饰, 表示“的多”, “甚至”, “更”, “一些”。如：This city is much more beautiful than before. 3.“比较级and比较级”意为“越来越” 。多音节比较级用“more and more形容词原级”形式。如：Its getting worse and worse. 4. “Which / Who is + 比较级？”比较A、B两事物, 问其中哪一个较时用此句型。如：Which T-shirt is nicer, this one or that one? 5. 使用形容词比较级时需注意以下几点：1

9、) than后面接代词时, 一般要用主格形式， 但在口语中也可使用宾格形式。 如：My brother is taller than I / me. 2) 当需要表示一方超过另一方的程度时，可以用much, a lot, a little, a bit, even, still等来修饰形容词比较级。注意: 比较级不能用very, so, too, quite等修饰。如： He is much more serious than Sam.3) 形容词比较级后面往往用连词than连接另一个比较的人或事物, 但在上下文明确的情况下, 形容词比较级可单独使用。如：My sister is tall,

10、but my aunt is taller. （四）练习达标。(A)、基础练习：写出下列形容词的比较级。tall long cold fast thicksmall strong hard new short wide fine late fat big thin red happy early easy heavy beautiful exciting interesting popular difficult useful important good far ill much bad many well(B)巩固提高：用所给词的适当形式填空。1.
