形容词比较级
比较级→原级
taller_________________
nicer_________________
bigger________________
heavier_______________
tall
nice
big
heavy
观察下面四个形容词的比较级变原级的时候,有什么不同吗?
1.形容词比较级和最高级变化规律
(1)大部分直接在后面加 er/est: tall — taller /est
(2)重读闭音节单词(辅+元+辅)
双写结尾辅音加er: big — bigger ; thin — thinner
(3)以辅音字母加y结尾,把y改为i,再加 er
heavy — heavier
(4)以e结尾的, 直接加r nice — nicer;late-later
(5)多数双音节词和多音节词在词前加more或most :如:boring, beautiful, expensive, interested
