五一假期作业Unit1-语法提升和综合训练 2025-2026学年鲁教版（五四学制）七年级英语下册

五一假期作业Unit1语法提升训练 一、知识必备 比较级和最高级是英语中的一种特殊语法现象，用来比较两个人、动物、事物或情况之间的差异，一般表示“更……；比较……”的意思。 只有形容词和副词有比较级和最高级的用法。 一、比较级的基本构成 1. 规则变化： 1　 一般单音节词或部分双音节词，其后直接加-er。例如：taller, smaller, younger 2　 以e结尾的词，加-r。例如：larger, nicer, later 3　 以“辅音字母+y”结尾的双音节词，变y为i加-er。happier, easier 4　 重读闭音节词尾只有一个辅音字母时，双写最后一个字母再加-er。 5　 例如：bigger, hotter 6　 多音节词和部分双音节词在词前加more构成比较级。例如：more beautiful, more careful 2. 不规则变化： 需单独记忆： good → better bad → worse many/much → more little → less 二、比较级的基本用法 1. 核心结构：A + be/动词 + 比较级 + than + B（A比B更……） 例句：My room is bigger than yours. （我的房间比你的大。） 例句：She runs faster than me. （她跑得比我快。） 2. 修饰比较级： 可用 much, a lot, a little, even, far 等加强或减弱程度。 例句： This book is much more interesting than that one. （这本书比那本有趣得多。） He is a little taller than his father. （他比他爸爸高一点。） 3. 否定结构：A + be/动词 + not + as/so + 形容词/副词原形 + as + B（A不如B……） 例句：Math is not as easy as English. （数学没有英语容易。） 4. 倍数结构：A + be + 数字 + times + as + 形容词原级 + as + B（A在……上是B的……倍） 例句：This building is twice as high as that one. （这座楼比那座楼高一倍。） 5. 特殊句型： (1) “the + 比较级, the + 比较级” 表示“越……，越……”。 例句：The harder you study, the better grades you will get. （你越努力学习，成绩就越好。） (2) “比较级 + and + 比较级” 表示“越来越……”。 例句：The weather is getting colder and colder. （天气越来越冷了。） 三、注意事项 1. 比较对象要一致，避免逻辑错误： 要用 that/those 代替前文提到的名词，避免重复。 ❌ 错误：The population of Beijing is larger than Tianjin. （不能把人口和城市直接比较，应该与天津的人口比较） ✅ 正确：The population of Beijing is larger than that of Tianjin. （that代替前文的population） 2. 比较级不可用于三者及以上的比较，三者及以上需用最高级。 一、刷刷能力 Ⅰ 用括号内所给单词的适当形式填空 1.
