形容词和副词的比较等级

一、形容词和副词的比较级、最高级的构成
1.规则变化类别 构成 图解助记
一般在词尾加__-er___或__ -est _ _
以字母 e 结尾加__-r___或__-st
__
单音节词 以重读闭音节结尾，如末尾只有
和部分双 一个辅音字母(辅元辅)，则__双
音节词 写末尾辅音字母再加__-er___或
__-est___
以“辅音字母+y”结尾的词，变
__y___为__i___再加__-er___或
__-est___
多音节词
所有多音节和部分双音节词，在
和部分双
词前加__more__或__most__
音节词

表格）
原级 比较级 最高级 原级 比较级 最高级
good/well better best farther farthest
far
bad/badly/ill worse worst further furthest
many/much more most older oldest
old
little less least elder eldest
二、形容词和副词比较等级的用法
1.原级的用法和句式
两者的同级比较用“as+形容词和副词的原级+as”（否定用“not + as/so +形容词或副词的原级+ as”）
Eg.This ruler is as long as that one. 这把尺子和那把尺子一样长。
Jim is not as/so tall as Tom. 吉姆不如汤姆高。
2.比较级的句式和用法
句式和用法 示例
“A+谓语动词+比较级+ than +B”用于两者之 You are taller than your brother. 你比你弟弟高。
间的比较，表示其中一个比另一个更…… He jumped higher than you. 他比你跳得高。
“比较级+ and +比较级”表示事物本身程度 He is running faster and faster. 他跑得越来越快。The city is becoming more and more beautiful.
的逐渐变化，意为“ 越来越…… ”
这个城市变得越来越漂亮了。
“the +比较级...，the +比较级...”表示一方程度
The more you eat, the fatter you will be.
的变化随着另一方的变化而平行变化，意为
你吃得越多，就会越胖。
“ 越……，就越…… ”
“Which/Who +系动词+比较级，A or B?”表示 Which sweater is cheaper, the red one or the blue one?
两个人或事物中哪一个/谁更…… 哪件毛衣更便宜，红色的还是蓝色的？
“A+系动词+ the +比较级+ of the two（+复数 Mary is the taller of the two girls.
名词）”表示两者中比较……的 玛丽是两个女孩中较高的。
【拓展延伸】
（1）修饰形容词或副词的比较级可以用 much, a lot, a little, a bit, even, far等，但不能用very, so, too等修
饰。
【记忆口诀】两多（much, a lot）两少（a little, a bit）一甚至（even），还有一个远（far）去了。
Eg.This story is much more interesting than that one. 这个故事比那个有趣得多。
（2）在比较结构中，被比较的事物应是同等成分，常用that或those代替前面的名词。
Eg.The workers in that factory are fewer than those in our factory.那个工厂的工人比我们工厂的工人少。
3.最高级的句式和用法
句式和用法 示例
She is the youngest in our class.
“the +最高级+ in/of...”，其中in后常跟表示组
她是我们班里年龄最小的。
织、团体之类的集体名词；of后跟名词或代
She is the youngest of the students.
词与句子的主语属于同一个概念范畴

climate change. In order to avoid creating greenhouse gases, the world should try to stop burning coal and riding in
cars.

humans need to act 20 to make that hope come true.” Let’s take action to protect our earth and save polar
bears.
