5、rm comparatives and superlatives with adjectives? 大多数形容词和副词有比较级和最高级的变化，即原级、比较级和最高级，用来表示事物的等级差别。原级即形容词、副词的原形，比较级和最高级有规则变化和不规则变化两种。 1) 规则变化 单音节词和少数双音节词， 在词尾加-er, -est来构成比较级和最高级。 GRAMMAR以不发音的e结尾的单音词和少数以- le结尾的双音节词只加-r，-stnicelargeablenicerlargerablernicestlargestablest以一个辅音字母结尾的闭音节单音节词，双写结尾的辅音字母，再加-er，

6、-estbighotbiggerhotterbiggesthottest以辅音字母+y结尾的双音节词，改y为i，再加-er，-esteasy busy easier busiereasiestbusiest少数以-er，-ow结尾的双音节词末尾加-er，-estclevernarrow cleverer narrowercleverestnarrowest其他双音节词和多音节词，在前面加more，most来构成比较级和最高级。importantmore importantmostimportant2) 不规则变化 原级 比较级 最高级 good wellbetterbestbad ill wo

7、rse worst old older / elder oldest / eldest much / many more most little less least far farther / further farthest / furthest 比较级有规律, 词尾加上-er两兄弟;要是以e来结尾, 只有小二(r)跟上去;重读闭音节词要牢记, 双写千万别忘记;要是“辅音+y”来结尾, 小艾(i)要把y来替, 再加-er两兄弟; 多音节词加上m-o-r-e, 你看这样多容易。Chant(口诀)最高级规则变化口诀 最高级，很容易，一般词尾加est。 (cheap-the cheapest)

8、词尾若有哑音e, 直接就加st。 (close-the closest) 重读闭音节， 单辅音字母要双写。 (big-the biggest) 辅音字母若加y, 记得把y变为i。 (friendly-the friendliest) 多音节，考考你，the most到底加哪里？ (popular-the most popular)3) 形容词、副词等级的用法原级的用法 1. 只能修饰原级的词：very，quite，so，too。如： He is too tired to walk on. My brother runs so fast that I cant follow him.(2)“甲+

9、be + not + as / so+形容词原级+as+乙” 甲不如乙如： This room is not as / so big as that one. “甲+助动词+not+动词原形+as / so+副词原级+as+乙”甲不如乙如： He doesnt walk as slowly as you.比较级的用法 1. 可以修饰比较级的词，much，a lot，far，的多，a little，a bit (一点儿)，even (甚至)，still (仍然)。如： Lesson One is much easier than Lesson Two.
