【知识要点】
一、形容词比较级和最高级不规则变化形式:
原级
比较级
最高级
good / well
better
the best
bad / ill
worse
the worst
far
farther / further
the farthest / the furthest
many / much
more
the most
little
less
the least
old
older / elder
the oldest / the eldest
二、(not) as...as的用法
as……as意为“和……一样”,not as……as意为“不及……”,表示同级的比较。
1. 基本结构:as + adj. + as,否定形式为:not as/so+ adj. + as,中间用形容词的原级。
eg: The book is as interesting as that one. (注意:第一个as不能用so替换)
2. 当as...as中间加名词时,结构为:as+ many/much + n. + as,否定形式为:
not as+ many/much + n. + as。需要注意的是:当名词为可数名词时,中间为“many+可数名词复数”,当名词为不可数名词时,中间为“much +不可数名词”。
eg: Tom has as many pictures as John.
3. as...as前面常常用almost,quite,nearly,exactly等程度副词表示比较的程度。:
eg: This cup is nearly as big as that one.
难点:在同一范围内比较时,必须把主语排除在被比较的范围之外。
eg 1:China is larger than any other country in Asia. (解析:中国是属于亚洲的,所以是在同一范围内,只能和其它对象进行比较)
eg 2:China is larger than any country in Africa. (解析:中国不属于非洲,所以是不同范围,可以和其中任意一个对象进行比较)
