2.
构成的规则变化:
(1)单音节词和少数双音节词一般在词尾后加-er
构成比较级或-est构成最高级，如：
(2)以字母e结尾的词只加
-r
或-st构成比较级
和最高级。
原级
比较级
最高级
nice
———
nicer
–———
nicest
fine
———
finer
———
finest
large
——
larger
———
largest
(3)重读闭音节词末尾只有一个辅音字母时,
先双写这个辅音字母,
再加-er或-est。
原级
比较级
最高级
big
–
bigger
–
biggest
thin
–
thinner
–
thinnest
hot
–
hotter
–
hottest
(4)以“辅音字母+
y”结尾的双音节词，先
改y为i,
再加-er或-est。
原级
比较级
最高级

happier
–
happiest
angry

angriest
(5)多音节词和部分双音节词在词前加more或most。
如：delicious
–
more
delicious
–
most
delicious
interesting
–
more
interesting
–
most
interesting
important
–
more
important
–
most
important
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。
