知识要点:
1、英语的比较级和最高级
形容词和副词有比较级和最高级,其词的变化规则如下:
一般情况下在词尾 +er 或est
tall - taller - tallest
(原级)(比较级)(最高级)
long - longer - longest
dear - dearer - dearest 在这个单词中r发音读为[r]
[¢dir] [¢dirist]
‚以e结尾的词,只需加r或st
late-later-latest
large-larger-largest
ƒ以辅音字母 + y结尾的双音节词,要去y变i再加er,est
heavy-heavier-heaviest
easy-easier-easiest
happy-happier-happiest
„重读闭音节词,末尾只有一个辅音字母时,要双写这个辅音字母,再加er,est
big-bigger-biggest
red-redder-reddest
…有些词的变化是特殊的,要特殊记:
原级 比较级 最高级
good/well-better-best
many/much-more-most
bad-worse-worst
little - less - least
在两个人或物之间进行比较,就要用比较级,我们看一下比较级句子的形成过程:
Mr. Read is tall.
Mr. King is taller.
把这两个简单句合并为一个带有比较状语从句的复合句:
Mr. King is taller than Mr. Read (is tall.)省略
由此可见,than后面的是主语,使用代词时一般用主格,口语中有时用宾格
eg:His brother is shorter than he.(主格)
下面根据谓语动词的情况给同学们两个句型以便掌握比较级的句型:
主语 + 系动词 + adj. 比较级 + than + 对比成分
Lily is younger than Li Tao.
Han Meimei is hungrier than Lucy.
‚主语 + 行为动词 + adv. 比较级 + than + 对比成分
Jim comes to school earlier than Mike.
Mike comes to school later than Jim.
形容词和副词的最高级用于三者或三者以上的人或物之间的比较,一般有一定的范围,常表达“最…之一”,这个范围一般用in或of的无定语来表达,形容词的最高级前一定要用定冠词“the”。liuxuepaper.com
