新目标八年级英语形容词比较级最高级专项练习

1.?形容词，副词比较级和最高级的概念。

形容词和副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、副词有三个级：原级(Positive Degree)，比较级(Comparative Degree)和最高级(Superlative Degree)。

?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---shorter---shortest ??long---longer---longest

? b.?如原级以e结尾，则比较级只加-r，最高级只加-st。 e.g.???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。e.g.???busy---busier---busiest????easy---easier---easiest

? d.?原级以重读闭音节结尾，而XX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?/ill/badly---?worse?---??worst

??????????????????many/much---?more---most??? little---less---least

far---?farther---?farthest????????????????old---?older?---??oldest

?????????? ??far---??further?????furthest???????????????old---?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比较级+and+比较级表示“越来越……”,多音节或者部分双音节的用”more and more +原级”

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.
