一般的都是加 er est 嘛 你把单词表后面特殊的那些多看看 就行了 还有一些多音节词 要用more most修饰来表示 这些都是特殊的 你就多积累就好 英语形容词比较等级有三个:原级,比较级和最高级一、规则变化: 1)单音节词末尾加-er(比较级),-est(最高级) 【例】 原级 比较级 最高级 great greater greatest small smaller smallest clean cleaner cleanest 2)单音节如以e结尾,只加-r(比较级),-st(最高级) 【例】 fine finer finest nice nicer nicest wide wider widest 3)闭音节单音节词如末尾只有一个辅音字母,须先双写这个辅音字母,再加-er(比较级),-est(最高级) 【例】 big bigger biggest hot hotter hottest red redder reddest 4)少数以-y,-er,ow,-ble结尾的双音节词,末尾加-er(比较级),-est(最高级)。以-y结尾的词,如-y前是辅音字母,则变y为-i,再加-er和-est。以-e结尾的词只加-r和-st。 【例】 clever cleverer cleverest narrow narrower narrowest able abler ablest easy easier easiest 5)其它双音节和多音节词皆在前面加单词more和most。 【例】 careful more careful most careful difficult more difficult most difficult delicious more delicious most delicious二、不规则good--better--bestwell--better--bestbad--worse--worstill--worse--worstbadly--worse--worstmany--more--mostmuch--more--mostfar--farther,further--farthest,furthestlittle--less--leastold--older,elder--oldest,eldestlate--later,latter --latest,last三、比较级的用法1. 同级比较两个比较对象程度相同时,用“as+形容词原级+as的结构”例如: Tom is as tall as his brother. My hair is as long as mine.在这两种结构中,第一个as是副词,而第二个as是连词;在第二个as的后面接名词、句子或代词的主格(一般不要接代词的宾格)。例如: His bedroom is not as big as his sister's. It is not so hot as yesterday.[学生两人一组使用as… as… 及 not as(so) … as…练习同级比较。]2、在比较级 + than的结构前可以加上某些副词类的词,以对其进行修饰,如:far(远),even(甚至),much(许多),still(更,还),a lot(许多),a little / bit(一点),rather(相当地),等等。例如: She’s a little more outgoing than me. My bike is much newer than his. 3、 比较级中的两个特殊作用的结构是:a. The + 比较级 + 句子,the + 比较级 + 句子 。它表示的意义是"越(怎么样就)越(怎么样)",在这个结构中的两个"比较级"不要求一定词性相同,它们各自的词性要依句子的需要而定。例如: The harder you work at your study, the better grades you will have. 你学习越努力,你的成绩就越好。The more we get together, the happier we’ll be. 朋友越多, 我们就越高兴。[Ask and answer in groups to make some new sentences.]b. 比较级+ and + 比较级。它表示的意义是"越来越(怎么样)",在这个结构中的两个 "比较级"则要求词性相同。例如: Our country becomes more and more beautiful.When spring comes, the weather is warmer and warmer. 4、 比较对象中一方不及另一方时,用“not as(so)+形容词原级+as ”或“less+形容词原级+ than”的结构。 He is not as careful as his sister. == He is less careful than his sister.== His sister is more careful than he.[Ask and answer in groups to make some new sentences.] 5、 在两者之中选择“较为、、、 ” 的一个, 比较级之前加the.例如: Amy is the taller of the two girls. Of the two books, the one on the right is the better.四、最高级的用法 ①三者或三者以上相比,表示最高程度时,用“ the十最高级”的结构表示.这种句式一般常有表示比较范围的介词短语.例如: Zhang Hua is the tallest of the three. He works (the) hardest in his class. ②最高级可被序数词以及 much,by far,nearly,almost,by no means,not quite,not really,nothing like等词语所修饰. 例如: This hat is by far/much/nearly/almost/not nearly/by no means/not quite/nothing like the biggest. How much did the second most expensive hat coat? ③表示“最高程度”的形容词,如 excellent,extreme,perfect等,没有最高级,也不能用比较级. ④形容词最高级修饰作表语或介词宾语的名词、代词时,被修饰的词往往省略. He is the tallest(boy) in his class. ⑤作状语的副词最高级前可以不加定冠词.例如 0f all the boys he came(the) earliest.
