小学五年级英语:形容词与副词的比较级

形容词与副词的比较级

📚 知识点讲解

一、什么是比较级?

当我们想比较两个人或两件事物时,就要用到比较级。比如"Tom比Jerry高",这里的"更高"就是比较级。

比较级的标志词:than(比……)

二、比较级的构成规则

情况 变法 例子
一般情况 直接在词尾加 -er tall → taller, small → smaller
以字母e结尾 加 -r nice → nicer, large → larger
以"辅音+y"结尾 把y改为i,再加 -er happy → happier, angry → angrier
重读闭音节,末尾只有一个辅音字母 双写该字母,再加 -er big → bigger, hot → hotter, thin → thinner
多音节词和部分双音节词 在前面加 more beautiful → more beautiful, important → more important

三、不规则变化的比较级

有些形容词和副词的比较级变化比较特殊,需要单独记忆:

原级 比较级 例句
good / well better This book is better than that one.
bad / badly worse My headache is worse today.
many / much more I have more books than you.
little less I have less money than him.
far farther / further My school is farther than yours.

四、比较级的基本句型

句型 结构 例句
A比B更…… A + be + 比较级 + than + B Tom is taller than Jerry.
A比B更……(动词) A + 动词 + 比较级 + than + B She runs faster than me.
越来越…… 比较级 + and + 比较级 It's getting hotter and hotter.
越……就越…… The + 比较级 + ... , the + 比较级 + ... The more you read, the smarter you will be.

五、比较级的五大句型详解

句型一:A + be + 比较级 + than + B

这是最常用的比较级句型,表示"A比B更……"。

Tom is taller than Jerry. (Tom比Jerry高。) This book is more interesting than that one. (这本书比那本书更有趣。) Summer is hotter than spring. (夏天比春天热。)

注意:than后面的人称代词如果单独使用,要用主格(I, he, she, we, they),但如果后面有动词也可以接受。

句型二:A + 实义动词 + 比较级 + than + B

She runs faster than me. (她跑得比我快。) Mike studies harder than before. (Mike比以前学习更努力了。) My father gets up earlier than my mother. (我爸爸比我妈妈起得早。)

句型三:比较级 + and + 比较级

表示"越来越……",用于描述持续变化的过程。

It is getting hotter and hotter. (天气越来越热了。) The city is becoming more and more beautiful. (这个城市变得越来越漂亮了。) My English is getting better and better. (我的英语越来越好了。)

句型四:The + 比较级 ... , the + 比较级 ...

表示"越……就越……",常用于谚语和格言。

The more you read, the smarter you will be. (你读得越多,就越聪明。) The more careful you are, the fewer mistakes you will make. (你越仔细,犯的错就越少。) The earlier you start, the earlier you finish. (你开始得越早,就完成得越早。)

句型五:much / even / a little + 比较级

比较级前面可以加程度副词来加强或减弱语气。

修饰词 作用 例句
much ……得多 This box is much heavier than that one.
even 甚至更…… Today is even hotter than yesterday.
a little 稍微…… I'm a little taller than my sister.
a lot ……得多 He is a lot fatter than before.
far 远远更…… This is far better than I expected.

六、比较级的常见错误

错误一:双重比较

❌ She is more taller than me. ✅ She is taller than me.

单音节词已经加 -er 了,就不能再加 more。

错误二:比较对象不一致

❌ My hair is longer than you. ✅ My hair is longer than yours (your hair).

比较的对象必须对等:头发不能和"你"比,要和"你的头发"比。

错误三:用错不规则变化

❌ My grades are gooder than before. ✅ My grades are better than before.

good/well 的比较级是 better,不是 gooder。

七、比较级与最高级的区别

比较级 最高级
用法 比较两者 比较三者或以上
标志词 than of / in / among
变化 -er / more -est / most
例句 Tom is taller than Jerry. Tom is the tallest in his class.

八、生活中的比较级

在日常对话中,比较级非常常见:

购物时:This one is cheaper than that one. (这个比那个便宜。) 比较外貌:She looks younger than she really is. (她看起来比实际年龄小。) 谈论天气:It's getting colder. Let's put on more clothes. (越来越冷了,我们多穿点衣服吧。) 比赛时:I can jump higher than you! (我能跳得比你高!)

常用比较级短语

短语 意思 例句
more than 多于 I have more than 100 books.
less than 少于 It costs less than 10 yuan.
better than 比……好 This is better than that one.
rather than 而不是 I like apples rather than oranges.
