知识拓展：
1、用比较级表示倍数
A+V+倍数+比较级+than B “A 比B大（小长 ）几倍”
A+V+倍数+as +adj/adv+原形+as+B A是B的几倍
A+V+倍数+the + n + of B A是B的几倍
The bridge is twice wider than that one.
这座桥比那个桥宽二倍
=The bridge is three times as wide as that one.
=The bridge is three times the width of that one.
这座桥是那个桥的三倍.
2、“A+系动词+the+比较级+of+the two（+复数名词）”意为“A是两者中比较…的”，例如：He is more outgoing of the two boys.\ Ann is the more outgoing of the two girls.
3、表示“越来越…”可以用“比较级+and+比较级”结构
表示“越 …就越…”可以用“The+比较级…，the+比较级…”
The weather is getting hotter and hotter.
The more you smile, the happier you will feel.
用比较级结构表示最高级含义
用比较级的结构表示最高级的含义时，要看比较范围是否包括被比较对象本身，如果包括，则须把本身排除。
than + any other +单数名词 \ the +other +复数名词 \ the others
=no+n 单数+V+as +adj /adv原形+as +…
Tom is taller than any other student \ the other students\ the others in our class.=No student in our class is as tall as Tom .=Tom is the tallest in our class.
