24版八上Unit3重难点语法知识突破—比较与比较级结构详细解析（附练习题+答案） 比较级和最高级是中考英语语法的重要考点，常用于句子中表达比较关系。掌握比较级和最高级的用法，不仅有助于语法题得分，还能提升写作表达的准确性和丰富性。 一、比较级和最高级的基本概念 定义 比较级（comparative）：表示两者之间的比较，一般形式为形容词/副词 + er 或 more + 形容词/副词 最高级（superlative）：表示三者或以上的比较，一般形式为形容词/副词 + est 或 most + 形容词/副词 二、比较级的用法 1.两者比较 结构：A + be/动词 + 比较级 + than + B 例句： Tom is taller than Jack.（汤姆比杰克高） This book is more interesting than that one.（这本书比那本更有趣） 2.不规则比较级 good → better well → better bad → worse far → farther/further 例句： She sings better than her sister. His plan is worse than ours. 3.双重比较结构 as…as：表示两者相等 not as…as / not so…as：表示不如 例句： He is as tall as his brother.（他和他哥哥一样高） This exercise is not as easy as I thought.（这个练习没有我想的容易） 三、最高级的用法 1 表示三者或以上的比较 结构：the + 最高级 + 名词 + in/of + 范围 例句： Tom is the tallest boy in the class.（汤姆是班上最高的男孩） This is the most interesting book of all.（这是所有书中最有趣的一本） 2 不规则最高级 good → best well → best bad → worst far → farthest/furthest 例句： He is the best student in our class. This is the worst day of my life. 四、比较结构的拓展用法 1 代词作比较 I am taller than he. / He is taller than me. 注意：书面语 prefer 用主格 he/she，而口语中常用宾格 me/her 2 多词比较 more/less + 形容词/副词 例句： This problem is more difficult than I expected. She works less efficiently than her colleague. 3 双重比较（强调） the…er…，the…er…：表示“越…越…” 例句： The more you practice, the better you get.（你练习得越多，越好） The harder he works, the more he earns.（他工作越努力，赚得越多） 五、常见易错点 比较级后必须用 than Tom is taller I. Tom is taller than I. as…as 表示相等，不加 than He is as tall than his brother. He is as tall as his brother. 最高级前要加 the She is tallest girl in the class. She is the tallest girl in the class. 不规则比较级和最高级记忆错误 good → better → best bad → worse → worst 双重比较结构注意主谓搭配 The more you practice, the better you get.（主语保持一致） 六、专项练习 一、选择题 1.Tom is ___ than his brother.
