购物场景加分句比较两家店时，除了 cheaper/more expensive，还可以说：the market is busier（更热闹）、the café is quieter（更安静）、this bag is lighter（更轻）。多准备几个形容词，口语显得有料。

最高级怎么用最高级后面常接范围：the cheapest in the shop（店里最便宜）、the best of all（所有里最好）。注意：范围是"地点/群体"时用 in；是"同一类人/物"时用 of。
三个必背细节
① than 不能丢：比较级句子必须有 than，漏了写作扣分。
② 不要双重比较：不能说 more cheaper，cheaper 本身就够了。
③ 最高级前面一般加 the：the cheapest（最便宜），"最"字前面别忘 the。
⑤ 场景全解：挑外套时怎么比（配图记忆）
场景
例句
记忆点
1 谁更好看
The blue one is nicer than the black one.
nice→nicer，加 than
2 谁更贵
The blue jacket is more expensive than the black one.
expensive 长词用 more
3 谁更便宜
The black one is cheaper.
cheap→cheaper
4 哪件最好
This is the cheapest jacket in the shop.
the + cheapest 最高级
5 一样好
This one is as good as that one.
as...as 中间用原级 good
6 不规则
My old phone is worse than yours. / It's better.
bad→worse；good→better
店员对话里的比较（跟读体会）
A: Which jacket do you prefer? B: The blue one is nicer, but it's more expensive than the black one. A: The black one is cheaper — only twenty-five pounds. It's as good as the blue one. B: Great, I'll take the black one. It's the best value!
加分句型：比较级 + and + 比较级表示"越来越……"：The shop is getting busier and busier.（这家店越来越热闹了。）写作里用一句，比平铺直叙更生动。
⑥ 中国学生 5 大高频错误诊断
错误 1：漏 than ✗ The blue one is nicer the black one. → ✓ The blue one is nicer than the black one. 口诀：有比较级，必有 than。
错误 2：双重比较 ✗ It is more cheaper. → ✓ It is cheaper. more 和 -er 不能叠用，二选一。
错误 3：长词加 -er ✗ This is expensiver than that. → ✓ This is more expensive than that. 长词（expensive/interesting）前面加 more。
错误 4：最高级漏 the ✗ It is cheapest in the shop. → ✓ It is the cheapest in the shop. "最……"前面一般要 the。
错误 5：不规则记错 ✗ My bag is gooder than yours. → ✓ My bag is better than yours. good→better→best；bad→worse→worst，单独背。
⑦ KET 考点与真题演练
题型
怎么考
应对
Reading Part 5 完形
短文挖空，填比较级 -er 或 more
看到 than → 比较级
Reading Part 2 多匹配
匹配"谁想要便宜的/最好的"
抓 cheaper/best 等词
Writing Part 6 便条
比较两个商店/商品
用 A is cheaper than B 拿分句
Listening Part 3 对话
听两人比较商品选结论
抓 but 转折后的比较级
Speaking Part 2
比较两张图里的人/物
The man is taller than the woman.
真题风格演练（KET 出题方式）
真题风格 · Part 5完形填空：The blue jacket is (1) ___ (nice) than the black one, but it is (2) ___ (expensive).
(1) nicer（than → 比较级，nice 加 r）；(2) more expensive（长词加 more）。
真题风格 · Part 2匹配：女孩想给爸爸买"最好但不太贵"的礼物。A. the cheapest B. the best value C. the biggest
B。best value = 性价比最高，正好"好又不太贵"。
真题风格 · Speaking看图比较：图 A 的店人很多，图 B 的店人少但更贵。说 2 句。
参考：Shop A is busier than Shop B, but Shop B is more expensive. Shop A is the cheapest.
真题风格 · Listening听对话："The red bag is nice, but the blue one is bigger and only a little more expensive." —— 女士更可能买哪个颜色？
蓝色（blue）。but 后说蓝色更大、只贵一点点，是推荐倾向。
听力里听比较级的技巧两人对话常先说一个优点，再用 but 转折引出真正的结论。比如 "It's nice, but it's more expensive."——答案往往在 but 后面。听 Part 3 时把 but 后的比较级圈出来。
