比较级的用法

一、概念：当我们要表达“更…‖和“最…”时，就要用到形容词的比较级和最高级。

如： I’m taller than you. 我比你高。 He is the tallest. 他是最高的。

二、形式变化

1. 规则形容词比较级是在形容词后加er

如：tall –taller long –longer strong –stronger

最高级是在形容词后+est

如：tall –tallest long –longest fresh –freshest strong—strongest 2. 但要注意三个情况：一是以字母e结尾则只加 r/st

如：nice –nicer –nicest late –later –latest fine –finer –finest

二是以辅音字母+y结尾要把y变i+ er/est

如： easy –easier –easiest early –earlier –earliest happy –happier –happiest

三是如果以重读闭音节结尾且末尾只有一个辅音字母（辅元辅），则要双写这个辅音字母+er/est.

如：big –bigger –biggest hot –hotter –hottest fat –fatter –fattest

3. 以上变化是单音节或部分双音节单词的变化，如果是多音节单词（比较长的单词），则是在前面加more 来构成比较级，加most来构成最高级

如： delicious –more delicious –most delicious

popular –more popular –most popular

famous –more famous –most famous

interesting –more interesting –most interesting

4. 还有一些形容词的比较级和最高级变化是不规则的，需要单独记忆如： good/well –better –best； bad/ill –worse –worst； many/much –more –most； little –less –least； far –farther/further –farther/furthest

三、用法

1. 比较级用法：通常，只要将两个人或事物实行比较时，就要用比较级，有时会给出明确的比较对象（比较对象能够是一个词，也能够是一个短语）。

如：He is taller than his father. 他比他父亲高。

Days in summer are longer than those in winter.夏天的白天比冬天的长。而有时则是暗含比较含义，没有给出比较对象，这时也要用比较级，如：I feel better today./ If you work hard, you can get higher grades. 绝大部分情况下，我们能够通过以下句型来判断一定用比较级。

①后面有than，因为than本身是“比”的意思，后加比较对象，自然前面的形容词要用比较级。

②前面有much / even/ a little/a lot 修饰时，much/even/ a little/a lot 这些词用来修饰形容词时，只能修饰形容词的比较级，那么自然当这些词出现时，后面一定加形容词的比较级。

e.g.: He feels much better today. I can do even better next time.

③选择疑问句。

e.g.: Which do you like better, cycling or rowing?

Who is taller, Michael or you?

④前句出现比较对象。

e.g.: It’s cold today, and it will be colder tomorrow.

⑤当表达越来越…时，两个形容词都要用比较级。 e.g.: The weather gets colder and colder.

如果是多音节形容词，则在形容词前加more and more 就可以。 English becomes more and more important.

2. 最高级的用法：当三个以及三个以上人或事物比较时，用最高级。要注意的是，形容词最高级前必须加定冠词 the。我们可以通过以下句型来判断，形容词一定要用最高级。

①后面有in + 范围时。

e.g.: He is the tallest in our class. Beijing is the biggest city in China.

②后面有of +the three/all 时。（三个、所有当中）

e.g.: This one is the most difficult of the three problems.

Russia is the biggest of all the countries.

③当选择疑问句有三个或更多选项时。

e.g.: Which is the highest mountain, Mount Tai, Mount Hua or

Mount Emei?

④在one of 后面常加形容词最高级。

Liu Xiang is one of the best runners in the world.

⑤在序数词后 + 形容词最高级。

The Yellow River is the second longest river in China.
