形容词或副词比较级和最高级的构成
1）规则变化
单音节词和少数双音节词词尾加er/est变为比较级/最高级。（加er/est方法与动词变过去式加ed方法相同）。
Eg. tall – taller/tallest nice – nicer/nicest
big – bigger/biggest easy – easier/easiest
clever – cleverer/cleverest (clever双音节)
多音节词和一些双音节词在该词前加more/ most变为比较级/最高级。以ly结尾的副词除early以及不规则变化外，也应加more/most。
Eg. interesting – more/most interesting
careful – more/most careful
slowly – more/most slowly
