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.
