形容词最高级和比较级
构成原则 原级 比较级 最高级

shortest
以e结尾加-r, -st large brave larger braver largest
bravest
重读闭音节，且只有一个辅音字母结尾时，双写最后一辅音字母加-er, -est hot big thin hotter bigger thinner hottest
biggest
thinnest
辅音字母+y结尾，y→i加-er, -est happy pretty happier prettier happiest
prettiest
比较级：用于两者之间进行比较
......动词+比较级+than....... (...比...更...)
......the+比较级+of the two (两者中，比较...的那个)
e.g. Tom is taller than Jim.
Tom is the taller of the two.
最高级：表示三者或三者以上的比较，意为“最…”
句中常带有表示比较范围的介词in…或of…
e.g. Yao Ming is the tallest of the players.
注：形容词最高级前必须加the
e.g. Tom is the tallest in his class.
Pattern practice

2.A: Bob, John and Dan are all tall.

three.
3.A: Who’s taller---Bob or John

5.
