情景导入
地理老师搞了一场英文抢答赛，第一题就是：What's the highest mountain in the world?（世界最高的山是什么？）全班齐喊：Qomolangma! It's 8,844.43 meters high!（珠穆朗玛峰，高 8844.43 米！）
第二题难了一点：Which is deeper, the West Lake or Qiandao Lake?（西湖和千岛湖哪个更深？）比较两者用比较级（deeper），三者及以上选第一用最高级（the highest）——这就是本单元的主线语法。

句型与语法
① 最高级的构成
| 类型 | 规则 | 例子 |
|---|---|---|
| 单音节词 | 加 -est（以 e 结尾只加 -st） | high → the highest, large → the largest |
| 辅音字母 + y 结尾 | 变 y 为 i 加 -est | heavy → the heaviest |
| 重读闭音节 | 双写末尾字母加 -est | big → the biggest, hot → the hottest |
| 多音节词 | most + 原级 | popular → the most popular |
| 不规则 | 单独记 | good/well → best，bad → worst，many/much → most |
② 最高级的三个黄金句型
- the + 最高级 + in/of 范围：Qomolangma is the highest mountain in the world.
- one of the + 最高级 + 复数名词：Hangzhou is one of the most beautiful cities in China.
- 比较级 + than any other + 单数名词（同类比较）：The Yangtze River is longer than any other river in China. = It is the longest river in China.
③ 数字 + 单位 + 形容词（表尺寸）
- Qomolangma is 8,844.43 meters high.（数词 + meters + high/long/deep/wide）提问用 How high is Qomolangma?
听说训练
"中国之最"问答操练：
- A: What's the longest river in China? — B: The Yangtze River. It's about 6,300 kilometers long.
- A: How large is the Taklamakan Desert? — B: As far as I know, it's the biggest desert in China.
跟读要点：最高级前的 the 不能吞掉；读大数字时按"thousand—hundred"分节，逗号就是停顿点。
辨析对比
① 两者比较用比较级，三者以上用最高级
- Which is bigger, Shanghai or Hangzhou?（两个城市比）Which is the biggest city of the three?（三个城市比）
② 最高级判断三信号
| 信号 | 例句 |
|---|---|
| in/of 范围短语 | the tallest boy in our class |
| one of + 复数 | one of the oldest cities |
| 序数词 + 最高级 | the second longest river（第二长的河） |
文化角
珠穆朗玛峰的英文名 Qomolangma 来自藏语，意为"大地之母"；西方也叫它 Mount Everest。1960 年中国登山队首次从北坡登顶，2020 年中国测量队公布最新"身高"8,848.86 米。而大熊猫作为"最可爱的外交官"，在全球动物园都是顶流——用英语介绍珠峰和熊猫，是向世界讲中国的经典素材。
易错点
- 最高级漏 the：Qomolangma is highest mountain. ❌ → the highest mountain ✅
- one of 后接单数：one of the longest river ❌ → one of the longest rivers ✅（必须复数）
- than any other 后接复数：taller than any other trees in the park ❌ → than any other tree ✅（单数）
- 双重最高级：the most easiest ❌ → the easiest ✅（-est 和 most 不能同时用）
中考真题
Hangzhou is ______ city I have ever visited, so I'd like to come again with my family.
A. more beautiful B. the more beautiful C. most beautiful D. the most beautiful
✏️ 点击查看解答
答案：D
解析：句中 I have ever visited（我游览过的城市当中）暗含比较范围，"我去过的最美城市"要用最高级，且最高级前必须加 the：the most beautiful。A、B 是比较级，句中没有 than，排除；C 缺少定冠词 the。固定搭配记牢：the + 最高级 + 名词 + (that) sb. have ever done。
考点
- 单选与语法填空必考：最高级构成（双写、变 y、most）、the 的取舍、one of + 最高级 + 复数；
- "比较级 + than any other + 单数 = 最高级"的同义句转换是完形与写作的加分句式；
- 阅读理解常考"世界之最/动物保护"类说明文，抓数字和最高级词就能快速答题。
诵读 Read Aloud
Our world is full of amazing facts. Qomolangma, the highest mountain in the world, is 8,844.43 meters high. It is even higher than any other mountain on the earth, and thick clouds cover its top all year round. The Yangtze River, about 6,300 kilometers long, is the longest river in China and one of the longest rivers in the world. Among all the animals, I love pandas best. An adult panda weighs many times more than a baby one, but it spends more than ten hours a day eating bamboo. Pandas are one of the most popular animals in the world, and we should do everything we can to protect them.
诵读小贴士：朗读时注意三处考点句式——the highest... in the world、higher than any other mountain、one of the most popular animals。把数字读顺，介绍"中国之最"的作文就成功了一半。
