核心语法:形容词的原级比较(as...as...和not as/so...as...)
一、核心概念
原级比较用于表示两个人或事物在某方面程度相等或不等。基本结构为 as + 形容词原级 + as。
核心含义:
肯定式:“和……一样……”
否定式:“不如……”、“没有……那么……”
示例:
Tom is as tall as Mike.(汤姆和迈克一样高。)→ 程度相等
Tom is not as tall as Mike.(汤姆不如迈克高。)→ 程度不等
二、基本结构
1. 肯定式:as + 形容词原级 + as
表示“A 和 B 一样……”。
结构: A + be动词 + as + 形容词原级 + as + B
例句:
Tom is as tall as Mike.(汤姆和迈克一样高。)
This book is as interesting as that one.(这本书和那本书一样有趣。)
The weather today is as cold as yesterday.(今天的天气和昨天一样冷。)
My bag is as heavy as yours.(我的包和你的包一样重。)
注意: as...as 中间必须用形容词原级,不能用比较级。
He is as taller as his father.
He is as tall as his father.
2. 否定式:not as/so + 形容词原级 + as
表示“A 不如 B……”。否定句中既可以用 as...as,也可以用 so...as。
结构: A + be动词 + not as/so + 形容词原级 + as + B
例句:
Tom is not as tall as Mike.(汤姆不如迈克高。)
This book is not as interesting as that one.(这本书不如那本书有趣。)
The weather today is not as cold as yesterday.(今天不如昨天冷。)
My bag is not as heavy as yours.(我的包不如你的包重。)
注意: 否定句中,not as...as 和 not so...as 可以互换,但 so...as 在肯定句中不能使用。
He is not so tall as his father.
He is so tall as his father.(肯定句不能用 so)
三、as...as 与 not as/so...as 的选择
情况 结构 示例
A 和 B 一样(程度相等) A + be + as + 形 + as + B Tom is as tall as Mike.
A 不如 B(程度不等) A + be + not as/so + 形 + as + B Tom is not as tall as Mike.
判断技巧:
两者相同 → 用 as...as
两者不同 → 用 not as/so...as
四、与比较级的转换(高频考点!)
not as/so...as 结构可以转换为比较级 + than。
1. 转换为反义词的比较级
原句(not as...as) 转换句(比较级 + than)
This book is not as interesting as that one. This book is less interesting than that one.
Tom is not as tall as Mike. Tom is shorter than Mike.(用反义词)
This problem is not as difficult as that one. This problem is easier than that one.(用反义词)
The weather today is not as cold as yesterday. The weather today is warmer than yesterday.(用反义词)
五、修饰语的使用
为了表达程度上的细微差别,可以在第一个 as 前加上表示程度的副词。
修饰语 含义 示例
almost / nearly 几乎一样 She is almost as tall as her mother now.
just / exactly 正好一样 This box is just as heavy as that one.
quite 完全一样 He is not quite as experienced as he claims.
half 一半 This rope is half as long as that one.
twice / three times 两倍/三倍 This room is twice as large as that one.
六、比较对象对等(易错点!)
比较的双方必须对等可比。
The weather in Beijing is as hot as Shanghai.(天气 vs 城市)
The weather in Beijing is as hot as that in Shanghai.(用 that 指代 weather)
注意:
比较不可数名词或单数可数名词 → 用 that
比较复数名词 → 用 those
The students in Class 1 are as active as those in Class 2.
七、易错点与难点突破
1. as...as 中间误用比较级
He is as taller as his father.
He is as tall as his father.
2. 否定句中 as 与 so 的混淆
He is so tall as his father.(肯定句不能用 so)
He is as tall as his father.
He is not so tall as his father.(否定句可用 so)
3. 比较对象不对等
The weather in Beijing is as hot as Shanghai.
The weather in Beijing is as hot as that in Shanghai.
4. 修饰语位置错误
This rope is as twice long as that one.
This rope is twice as long as that one.
八、思维导图总结
九、记忆口诀
原级比较口诀:
同级比较 as...as,中间要用原级插;
肯定句中双 as 在,否定可用 so 代 as。
比较对象要对等,that/those 来帮忙;
倍数修饰放 as 前,twice, three times 在里边。
