形容词的比较级是在形容词的基础上变化而来的，它的变化规则是： ① 一般的直接在词尾加er ，如 tall - taller , strong - stronger , ② 以e结尾的，直接加r ，如 fine – finer ,
③ 以辅音字母加y结尾的，先改y为i再加er，如funny - funnier ④ 双写最后的字母再加er，如big – bigger, thin – thinner ,
hot – hotter
构成的不规则变化:
eg: good / well – better – best bad / badly – worse – worst
many / much – more – most little – less – least
far – farther / further – farthest / furthest 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) 4.翻译下列三个重点句子
