形容词和副词比较级、最高级(一)

1.形容词，副词比较级和最高级的概念。

2.形容词比较级和最高级的构成。

①单音节和少数双音节形容词、副词的规则变化情况：

a.在原级的词尾加-er变为比较级，加-est变为最高级。

e.g.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。

rge---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。

e.g.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。

e.g.fat---fatter---fattest big---bigger---biggest

②大多数双音节和多音节形容词、副词的规则变化，是在原级前加more变成比较级，加most变成最高级。

e.g.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)

③有少数形容词,副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。

e.g.good---better---best bad worse worst

ill

many more most little---less---least

much

farther farthest older ol dest

far old

further furthest elder eldest

④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。

e.g.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。

①表示两者“相等”用“as+形容词原级+as+比较对象”。

e.g.He is as tall as his mother．

English is as interesting as math.

②表示“不如”或“不相等”用“not +as／so+形容词原级+as+比较对象”。

e.g.It is not so／as cold today as yesterday．

Jack is not so/as tall as Tom.

③表示倍数，如“一半／两倍/3倍／4倍／……”等用“half／twice／three／four／…times +as…as…”结构。

e.g.I study twice as hard as you．

This room is three times as large as that one.

④用“形容词比较级+than引导的从句”进行两者的比较。

e.g.The earth is bigger than the moon．

This dress is more expensive than that one.

⑤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。

e.g.My brother is much older than I.

This bike is far better than that one.

⑥由and连接同一个形容词的两个比较级，可以表示“越来越……”。

e.g.I’m getting fatter and fatter．

I think English is becoming more and more difficult.

⑦用“the+比较级…+the+比较级…”，表示“越……就越……”。

e.g.The more you read，the more knowledge you will get．

The less junk food you eat, the healthier you feel.
