情景导入
班里来了一对双胞胎，长得几乎一样，性格却完全不同：姐姐安静爱读书，妹妹活泼爱说笑。怎么用英语描述这种差别？
I'm more outgoing than my sister.（我比我姐姐更外向。）My sister works harder than me.（我姐姐比我更用功。）
比较两个人或两样东西，就要用比较级。本单元我们学习比较级的变化规则、than 句型和 as...as 句型，学会把"谁更怎么样"说得清清楚楚。
核心词汇
| 单词/短语 | 词性 | 意思 | 比较级 |
|---|---|---|---|
| outgoing | adj. | 外向的 | more outgoing |
| hard-working | adj. | 勤奋的 | more hard-working |
| serious | adj. | 认真严肃的 | more serious |
| funny | adj. | 有趣搞笑的 | funnier |
| thin | adj. | 瘦的 | thinner |
| talented | adj. | 有天赋的 | more talented |
| care about | 短语 | 关心 | A good friend cares about me. |
句型与语法
核心句型：主语 + 动词 + 比较级 + than + 比较对象
- Tina is taller than Tara. （Tina 比 Tara 高。）
- Tom is more outgoing than Sam. （Tom 比 Sam 外向。）
比较级变化规则：
| 规则 | 例词 |
|---|---|
| 一般加 -er | tall → taller, fast → faster |
| 以 e 结尾加 -r | nice → nicer, late → later |
| 重读闭音节双写尾字母加 -er | big → bigger, thin → thinner |
| 辅音字母 + y 结尾，变 y 为 i 加 -er | funny → funnier, easy → easier |
| 多音节词前加 more | more outgoing, more serious |
| 不规则变化 | good/well → better, bad → worse, many/much → more |
as...as 句型：
- 肯定式"和……一样"：Lily is as tall as her sister. （中间必须用原级，不能用比较级！）
- 否定式"不如……"：I'm not as outgoing as my best friend.
比较级的修饰语：much、a little、even 可以放在比较级前加强或减弱程度——much taller（高得多）、a little heavier（重一点）。
听说训练
朋友对对碰（和同桌互相比较，轮流说句子）：
- Who is more outgoing, you or your best friend? — My best friend is. She talks more than me.
- Are you as tall as your father? — Not yet! He is much taller than me.
跟读要点：than 弱读成 /ðən/，别读成"then"；more outgoing 中 more 稍重读，突出比较意味。
辨析对比
① 比较级 + than vs as + 原级 + as
- than 前用比较级：She is taller than me.
- as...as 中间用原级：She is as tall as me. （as taller as 是典型错误！）
② more 与 -er 不能同时用
- more taller ❌ → taller ✅ 或（多音节词）more beautiful ✅
文化角
英语谚语里藏着不少比较级：Actions speak louder than words.（行动胜于言语。）Two heads are better than one.（三个臭皮匠，顶个诸葛亮。）西方文化聊到朋友时常说 A true friend reaches for your hand and touches your heart.——交朋友不必找和自己一模一样的人，性格互补往往更长久。
易错点
- double 比较级：She is more taller than me. ❌ → She is taller than me. ✅
- as...as 中用比较级：He is as older as me. ❌ → He is as old as me. ✅
- very 修饰比较级：very better ❌ → much better ✅（very 只能修饰原级）
中考真题
— Which do you like better, the East Lake or the West Lake?
— The West Lake, of course. It's much ______ than the East Lake in my hometown.
A. beautiful B. more beautiful C. most beautiful D. the most beautiful

答案：B
解析：本题考查比较级。句中出现 than，说明是两者比较，必须用比较级；beautiful 是多音节词，比较级在前面加 more，故选 B。
A 是原级，不能与 than 连用；C、D 是最高级，用于三者及以上的比较，与 than 矛盾。
考点
- 比较级是中考语法的绝对高频考点：看到 than 立刻锁定比较级，看到 as...as 立刻锁定原级；
- 三大命题点：① -er 与 more 的选择及拼写变化 ② much / a little / even 修饰比较级 ③ 不规则变化 better / worse / more；
- 写作加分："介绍朋友"类作文中写一句 "She is more outgoing than me, but we both love reading." 既显语法又显内容。
诵读 Read Aloud
My best friend Chen Jie and I are in the same class in Hangzhou. People say we are like twins, but in fact we are quite different. She is more outgoing than me, and she always makes everyone laugh. I am quieter and more serious, so I do better in exams. She runs much faster than me, but I swim better than her. Last month, we joined the school sports meeting together. She won the running race, and I got first in swimming! I think a good friend doesn't have to be the same as you. As long as we care about each other, being different makes our friendship even stronger.
诵读小贴士：朗读时圈出所有比较级（more outgoing, quieter, faster, better, stronger），注意 than 的弱读；背熟这一段，"我的好朋友"作文的比较级句子信手拈来。
