adj 比较级和最高级的变化规律
1. 词前变化:more/most + adj
(部分双音节词和多音节词)
2. 词尾变化:adj + er/est
(单音节和部分双音节词)
1)直接在词尾加-er/est tall-taller-tallest
2)以不发音e的结尾加-r/st nice-nicer-nicest
3)辅音字母+y结尾,改y为i再加-er/est
easy-easier-easiest
4)以一个辅音字母结尾的重读闭音节,双写再加-er/est
thin-thinner-thinnest
不规则变化:
原级比较级最高级
good / well better best
bad/ill worse worst
many/much more most
little less least
older oldest
elder eldest
farther farthest
further furthest
old
far

2. not as/so …as 与比较级的互转:
