中考英语 as+…+as 用法大全（零基础版）

一、基础核心用法：原级比较

as + 形容词/副词原级 + as 是英语中最基础的原级比较结构，表示 " 和……一样……"。

1.1 肯定句形式

结构：A + 动词 + as + 形容词/副词原级 + as + B

含义：A 和 B 在某方面程度相同

例句：

  • He is as tall as his father.（他和他爸爸一样高。）
  • She runs as fast as a rabbit.（她跑得和兔子一样快。）
  • This book is as interesting as that one.（这本书和那本书一样有趣。）

1.2 否定句形式

结构 1：A + 动词 + not + as + 形容词/副词原级 + as + B
结构 2：A + 动词 + not + so + 形容词/副词原级 + as + B

含义：A 在某方面不如 B（第二种形式更常用）

例句：

  • He is not as/so tall as his father.（他不如他爸爸高。）
  • She does not study as/so hard as her brother.（她学习不如她哥哥努力。）
  • This movie is not as/so exciting as I expected.（这部电影不如我预期的精彩。）
中考考点

否定句中 so...as 和 as...as 都可以使用，但在正式考试中优先使用 not so...as，得分更稳妥。

二、常见变体结构

2.1 带名词的结构：as + 形容词 + a / an + 单数可数名词 + as

结构：as + 形容词 + a/an + 单数可数名词 + as

含义：和……一样……的一个……

例句：

  • She is as good a student as her sister.（她和她姐姐一样是个好学生。）
  • It is as difficult a problem as that one.（这是一个和那个一样难的问题。）
易错点

形容词必须放在不定冠词 a / an 之前，不能说 a as good student as。

2.2 修饰可数/不可数名词：as many/much + 名词 + as

结构 1：as many + 可数名词复数 + as（修饰可数名词）
结构 2：as much + 不可数名词 + as（修饰不可数名词）

含义：和……一样多的……

例句：

  • I have as many books as you.（我的书和你的一样多。）
  • She drinks as much water as I do every day.（她每天喝的水和我一样多。）
  • He made as many mistakes as I did in the exam.（他考试中犯的错误和我一样多。）

2.3 比较对象为从句：as + 形容词 / 副词 + as + 从句

结构：as + 形容词/副词原级 + as + 主语 + 谓语

含义：和……（做某事）一样……

例句：

  • He is as tall as I am.（他和我一样高。）
  • She speaks English as well as her teacher does.（她英语说得和她老师一样好。）
  • It rained as heavily yesterday as it does today.（昨天下雨和今天一样大。）
简化规则

在口语和非正式写作中，从句中的谓语动词可以省略，直接用宾格代词：

  • He is as tall as me.（正确）
  • She runs as fast as him.（正确）

三、中考高频固定句型

这些是 as+...+as 结构衍生出的固定短语，是中考英语的必考点，必须熟练掌握。

句型 含义 例句
as soon as 一……就…… I will call you as soon as I arrive.（我一到就给你打电话。）
as long as 只要；和……一样长 As long as you work hard, you will succeed.（只要你努力，就会成功。）
as far as 就……而言；和……一样远 As far as I know, he is a good student.（据我所知，他是个好学生。）
as well as 和……一样好；也；而且 She plays the piano as well as her mother.（她钢琴弹得和她妈妈一样好。）
as…as possible 尽可能…… Please come as early as possible.（请尽可能早来。）
as…as usual 和往常一样…… He got up as early as usual this morning.（他今天早上和往常一样早起。）

3.1 重点解析：as well as

as well as 是中考最高频的考点之一，有两个核心含义：

  1. 表示比较：“和……一样好”

    • He sings as well as a professional singer.（他唱歌和专业歌手一样好。）

  2. 表示并列：“也；而且”（连接两个并列成分）

    • She as well as her classmates likes English.（她和她的同学都喜欢英语。）
主谓一致考点

当 as well as 连接两个主语时，谓语动词与前面的主语保持一致。

  • Tom as well as his friends is going to the park.（正确）
  • Tom as well as his friends are going到 the park.（错误）

3.2 重点解析：as…as possible

结构：as + 形容词/副词原级 + as possible

同义结构：as + 形容词/副词原级 + as sb. can/could

例句：

  • Please finish your homework as quickly as possible.
    = Please finish your homework as quickly as you can.（请尽快完成你的作业。）

四、易错点与注意事项

4.1 必须使用原级

as+...+as 结构中只能使用形容词或副词的原级，绝对不能使用比较级或最高级。

✅ 正确：He is as tall as his brother.
❌ 错误：He is as taller as his brother.
❌ 错误：He is as tallest as his brother.

4.2 形容词与副词的区别

根据前面的动词类型选择使用形容词还是副词：

  • 系动词（be, look, sound, smell, taste, feel, become, get 等）后用形容词
  • 实义动词后用副词

例句：

  • She looks as beautiful as her mother.（look 是系动词，用形容词 beautiful）
  • She dances as beautifully as her mother.（dance 是实义动词，用副词 beautifully）

4.3 比较对象必须一致

比较的双方必须是同类事物，否则会造成逻辑错误。

✅ 正确：The weather in Guangzhou is as hot as that in Shenzhen.（广州的天气和深圳的天气一样热。）
❌ 错误：The weather in Guangzhou is as hot as Shenzhen.（天气和城市不能比较）

替代词用法

为了避免重复，单数名词用 that 替代，复数名词用 those 替代。

  • The cars in this shop are as expensive as those in that shop.（这家店的车和那家店的一样贵。）

4.4 倍数表达法

as+...+as 结构常用于表达倍数，是中考的重要考点。

结构：倍数 + as + 形容词/副词原级 + as

含义：是……的几倍……

例句：

  • This room is twice as big as that one.（这个房间是那个房间的两倍大。）
  • He runs three times as fast as I do.（他跑得比我快两倍。/他跑的速度是我的三倍。）
中考常考倍数
  • twice（两倍）
  • three times（三倍）
  • four times（四倍）

4.5 程度修饰词

可以在 as+...+as 结构前加上程度修饰词，表示 “几乎一样”、“差不多一样” 等含义。

常用修饰词：almost, nearly, just, exactly, not quite, half 等

例句：

  • He is almost as tall as his father.（他几乎和他爸爸一样高。）
  • This book is not quite as interesting as that one.（这本书不如那本书有趣。）
  • The box is half as heavy as that one.（这个箱子只有那个箱子一半重。）
