b) 如果用于引申义,表“更进一步”、“更多”、“此外”等义,只能用further.如: We'll

further discuss it。 我们会进一步讨论它.

形容词原级用法

1)A+ 谓语+ as+ adj/adv 原级+ as + B :表示“A和B一样…… ”

eg: Tom is as tall as Bob。/ He does his homework as carefully as Tom.

A+ 谓语+(倍数)+ as+ adj/adv 原级+ as + B :表示“A是B的几倍…… "

This apple is threes times as big as that one. 这个苹果是那个苹果的三倍。

A+ 谓语否定形式(not)+ as(so)+ adj/adv 原级+ as + B 表示“A不如B……"

否定形式可用比较级进行句型转换。

Tom is not as/so tall as Bob.= Bob is taller than Tom.

as well as和…一样好\ 也,又

比较级用法

1) …比较级+ than…; eg: A horse is heavier than a sheep.

原级 前可用very、too、so、enough、rather、quite等修饰.
