核心概念
我们要明白形容词和副词有三个等级:
-
原级:形容词或副词的基本形式,用来描述事物的性质或状态。
(图片来源网络,侵删)- 例:
tall(高的),fast(快的),beautiful(美丽的)
- 例:
-
比较级:用于两者之间的比较,表示“更……”。
- 例:
taller(更高的),faster(更快的),more beautiful(更美丽的)
- 例:
-
最高级:用于三者或三者以上的比较,表示“最……”。
- 例:
tallest(最高的),fastest(最快的),most beautiful(最美丽的)
- 例:
构成规则
这是学习的核心,规则分为“规则变化”和“不规则变化”两大类。
A. 规则变化
| 原级 | 比较级 | 最高级 | 构成规则 | 例子 |
|---|---|---|---|---|
| 一般单音节词 | -er |
-est |
直接加后缀 | tall → taller → tallest |
| 以 e 结尾 | -r |
-st |
直接加 r/st | nice → nicer → nicest large → larger → largest |
| “辅音+y”结尾 | 变 y 为 i, +er |
变 y 为 i, +est |
辅音字母 + y 结尾的词 | happy → happier → happiest early → earlier → earliest |
| 重读闭音节词 | 双写辅音字母, +er |
双写辅音字母, +est |
以“辅音+元音+辅音”结尾的重读单音节词 | big → bigger → biggest hot → hotter → hottest thin → thinner → thinnest |
| 多音节词和部分双音节词 | more + 原级 |
most + 原级 |
在词前加 more/most | beautiful → more beautiful → most beautiful expensive → more expensive → most expensive interesting → more interesting → most interesting |
📌 特别注意:

- 双音节词:情况比较复杂,需要记忆。
-ful,-less,-ous,-ing,-ed等结尾的词用more/most。careful→more careful→most careful- 但也有一些双音节词用
-er/-est,clever,quiet,narrow等,考试中如果出现,通常会给出提示。
B. 不规则变化
这部分没有规律,必须牢记。
| 原级 | 比较级 | 最高级 |
|---|---|---|
good (好的) |
better |
best |
well (健康的,副词) |
better |
best |
bad (坏的) |
worse |
worst |
ill (病的) |
worse |
worst |
many (许多,修饰可数名词) |
more |
most |
much (许多,修饰不可数名词) |
more |
most |
little (少的) |
less |
least |
far (远的) |
farther (物理距离更远) further (抽象意义上的“更进一步”) |
farthest furthest |
old (老的) |
older (年龄大小) elder (长幼关系,只作定语) |
oldest eldest |
