专题：形容词的比较级、最高级。
1. 形容词的比较级和最高级的概念。
形容词可以靠改变形式来表示程度的不同。我们把这种变化形式叫做比较等级。要比较两个或两个以上的人或物时，就必须用形容词的比较级和最高级。
形容词有三个级：原级，比较级和最高级。
2. 形容词比较级和最高级的构成。
单音节和少数双音节形容词的规则变化情况：
a. 在原级的词尾加-er变为比较级，加-est变为最高级。
short(原级)--shorter(比较级)--shortest(最高级)
long(原级)--longer(比较级)--longest(最高级)
b. 如原级以e结尾，则比较级只加-r，最高级只加-st。
large---larger---largest nice---nicer---nicest
c. 如原级以“辅音字母+y”结尾，要将y改为i，再加-er，-est。
busy---busier---busiest easy---easier---easiest
d. 原级以重读闭音节结尾，而且末尾只有一个辅音字母(不含字母组合er等)，要双写这个辅音字母，再加-er，-est。
fat---fatter---fattest big---bigger---biggest
大多数双音节和多音节形容词的规则变化，是在原级前加more变成比较级，加most变成最高级。
beautiful(原级)--more beautiful(比较级)--most beautiful(最高级)
interesting(原级)--more interesting(比较级)--most interesting(最高级)
有少数形容词的比较级和最高级是不规则的。这些单词的变法需要大家识记。
good- -better-- bestbad/ ill worse worst
much /many more mostlittle- -less-- least
farther farthestolder oldest
farold
further furthestelder eldest
要注意有几个形容词的比较级和最高级有两种不同的形式，它们的意思也不同。
old---older较旧，较老---oldest最旧，最老/ old---elder较年长---eldest最年长。
far---farther较远---farthest最远(指距离)/ far---further进一步---furthest最深(指程度)
3. 形容词比较级的用法和相关句型。
表示两者“相等”用“as+形容词原级+as+比较对象”。
he is as tall as his mother．
english is as interesting as math.
表示“不如”或“不相等”用“not +as／so+形容词原级+as+比较对象”。
it is not so／as cold today as yesterday．
jack is not so/as tall as tom.
表示倍数，如“一半／两倍/3倍／4倍／……等用“half／twice／three／four／…times +as…as…”结构。
i study twice as hard as you．
this room is three times as large as that one.
用“形容词比较级+than引导的从句”进行两者的比较。
the earth is bigger than the moon．
this dress is more expensive than that one.
强调比较级超出比较程度时，形容词的比较级前可用much，far，a lot，still，no，a little，even，any,等状语来修饰。

this bike is far better than that one.
由and连接同一个形容词的两个比较级，可以表示“越来越……”
