13§1 最基本的规则
首先,我们要说明英文形容词有三个等级:原级、比较级和最高级,最基本的规则是根据音节的多少来分的。一般来说,单音节的形容词在词后面加er,就变成了比较级,加est 就变成了最高级,而双音节,或双音节以上的形容词,比较级是在词前面加more,最高级则是在词前面加most,举例来说,old, smart, strong, weak, high, low等等都是单音节的形容词,它们的变化如下:
原级比较级最高级
old older oldest
smart smarter smartest
strong stronger strongest
weak weaker weakest
high higher highest
low lower lowest
(2)形容词的词尾是y,而前一个字母是一个子音,则去掉y,加上ier,或iest:原级比较级最高级
lucky luckier luckiest
happy happier happiest
pretty prettier prettiest
dry drier driest
easy easier easiest
(3)单音节形容词的词尾是辅音,前一音是一个元音,则字尾必须重复一次,再加er 或est:
原级比较级最高级
fat fatter fattest
hot hotter hottest
wet wetter wettest
big bigger biggest
(4)以上的形容词,都是单音节的,以下的例子都是双音节的形容词:
原级比较级最高级
Difficult more difficult most difficult
Delicious more delicious most delicious
beautiful more beautiful most beautiful
Correct more correct most correct
stupid more stupid most stupid
significant more significant most significant
【练习一】
写出以下形容词的比较级:
1. small
2. slow
3. intelligent
4. expensive
5. tall
6. short
7. important
8. hot
9. wise
10. large
11. good
12. bad
13. many
13§2 特殊的比较级规则
完全不规则的变化:
英文中,有几个特殊的词,它们的比较级完全没有规则,以下是一些例子,同学们必须记住:
原级比较级最高级
Good/well better best
bad worse worst
Few/ little less least
Many/much more most
Far further furthest
13§3 比较级的用法
大多数比较级句子里会有than,以下是一些例子:
I am older than he.
His English is better than mine.
San Francisco is more beautiful than New Y ork.
His car is cheaper than your car.
He is the most diligent student in his class.
I like apples more than oranges.
He has more money than his brother.
He is stronger than his brother.
必须注意的是以下的句子是错的:
*I am older than him.
*She is smarter than me.
为什么错了呢?因为原来的句子应该是:
I am older than he (is).
She is more smart than I (am).
形容词各等级的用法:
1、原级(同级)比较:as…as…; not as(so)…as…
He is as good as she.
2、用比较级表示最高级:约翰是班里最高的男生。
John is taller than any other boy in the class.
John is the tallest boy in the class.
John is taller than any other boy.
3、the more… the more…表示“越……越……”:
The more books you read, the wider your knowledge is.
The more food you eat, the fatter you are.
4、more and more…表示“越来……越……”:
More and more students realized the importance of a foreign language.
Our country is getting stronger and stronger.
