上一页你已经认识了 shop / money / trousers 这些核心词。这一页解决另一个问题：光认词不够，KET 听力和口语要的是"一整套购物对话能接得住"。这一课专攻 10 个购物场景高频句——进门说 I'm looking for...、问价 How much is it?、试穿 Can I try it on?、嫌贵 That's too expensive、便宜 enough 吗——让你在 KET 听力 Part 2 听到任何一句都能立刻反应。
① 这一课怎么学（小白 4 步法）
总用时约 50 分钟，对话靠"情景模板"不靠背单词表：
1读句（10 分钟） 看第④⑤部分：10 个购物句型长什么样、买卖双方各说什么。
2辨错（10 分钟） 做第⑥部分错误诊断，把 try it on / costs 后接价钱抄 3 遍。
3套句（15 分钟） 背第⑧部分 10 个句型，每个换成你自己想买的东西再说一遍。
4成段（15 分钟） 做第⑨部分口语，用 6 句模拟一次完整买 T 恤对话。
本课的小目标学完做到三件事：① 会用 I'm looking for... 说出你想买什么；② 会用 Can I try it/them on? 问试穿；③ 会用 It costs... / That's too expensive. / cheap enough 三句评价价格。
② 一图看懂全课（思维导图）
购物对话按"进店→问价→试穿→评价→买单"五步走。

读法：五步走正好是 KET 听力短对话的顺序，听到哪句就知道对话进行到哪一步。
③ 先认识它：为什么"对话句"比"单词"更拉分
一句话：KET 听力考的不是"你认不认识 price 这个词"，而是"店员说 Can I help you? 你能不能用 I'm looking for... 接回去"。
比如 Flyers 阶段你只会说 How much?；KET 店员会说 Can I help you?，你得回 I'm looking for a T-shirt in size medium。再比如嫌贵，中式英语说 I don't want, too expensive，KET 标准说法是 That's too expensive. Have you got anything cheaper?。
为什么这些句子最拉分KET 听力 Part 2 每次都有一段店员-顾客短对话，考官就看你能不能抓住"顾客到底买了什么、嫌不嫌贵、要什么码"。这 10 个句子覆盖了对话里 80% 的关键信息。
记对话的正确姿势不要背中文翻译，背"上下句配对"：店员问 Can I help you? ↔ 顾客答 I'm looking for...。整对读熟，考场听到上句就能预判下句。

⑤ 五大使用场景全解（配图记忆）
场景
对话
记忆点
1 进店
— Can I help you? — I'm looking for a T-shirt.
店员主动开口，顾客说找什么
2 问价
— How much is it? — It costs 80 yuan.
cost 主语是物，不是人
3 试穿
— Can I try it on? — Sure. The changing room is over there.
try on 代词放中间：try it on
4 嫌贵
— That's too expensive. Have you got anything cheaper?
too + 形容词 = 太…（过头）
5 决定买
— It's cheap enough. I'll take it.
enough 放形容词后；take = 买
cost 与 spend 主语别搞反东西"售价多少"用 It costs 50 yuan.（主语是 it/东西）；人"花了多少钱"用 I spend 50 yuan on it.（主语是人）。听力里一听到 it costs 就记数字。
⑥ 中国学生 5 大高频错误诊断
错误 1：try on 代词位置错 ✗ Can I try on it? → ✓ Can I try it on? 动词+副词短语（try on / put on / take off），代词 it/them 必须放中间：try it on，不能 try on it。但名词可放后面：try the shoes on = try on the shoes。
错误 2：cost 与 spend 主语混 ✗ I cost 80 yuan on the shirt. → ✓ The shirt costs 80 yuan. / I spend 80 yuan on the shirt. cost 主语是物（It costs...），spend 主语是人（I spend...on sth）。
错误 4：too 与 very 混用 ✗ The shirt is very expensive, I'll take it. → ✓ The shirt is too expensive. I won't take it. very expensive = 很贵（但还能买）；too expensive = 太贵了（买不起/不买）。嫌贵不买用 too。
错误 5：I'll take it 说成 I'll buy it ✗ I want buy it. / I'll buy it. → ✓ I'll take it. 商店里"我买了"地道说法是 I'll take it（不是 I'll buy it，也不是 I want buy it——want 后要 to buy）。
⑦ KET 考点与真题演练
题型

Listening Part 2 选图
听店员-顾客对话，选"顾客最后买了什么"
抓 I'm looking for / try on / I'll take it
Listening Part 3 判断对错
长对话判断"价格有没有打折""尺码有没有"
抓 too expensive / cheaper / smaller size
Reading Part 1 短信息
读商店促销通知，三选一选同义句
抓 sale / discount / costs
Speaking Part 2 互动
和搭档讨论"去哪儿买生日礼物"
用 How much is it? / It costs... / too expensive
Writing Part 6 短消息
给朋友写购物建议
用 cheap enough / I'll take it / try on
真题风格演练（KET 出题方式）
真题风格 · KET Listening Part 2 选图对话：Shop assistant: "Can I help you?" Girl: "Yes, I'm looking for a blue T-shirt." Assistant: "How about this one? It costs 60 yuan." Girl: "Hmm, have you got a smaller size?" 问题：女孩最后会做什么？
A. 买这件大码 T 恤 B. 看小一码的 T 恤 C. 买蓝色外套
B。have you got a smaller size = 要看小一码，说明她没买这件大的。
真题风格 · KET Part 5 完形自填— How much ___ this jacket? — It ___ 200 yuan. That's too expensive ___ me. Have you got anything cheaper?
is / costs / for。How much is this jacket?（单数）；It costs 200 yuan.；too expensive for me。
真题风格 · KET Speaking Part 2你和搭档要给朋友买生日礼物。用英文讨论：① 你想买什么；② 问价格；③ 评价贵不贵。
参考：A: I'm looking for a book for Sam. How much is this one? B: It costs 80 yuan. A: That's too expensive. Have you got something cheaper? B: How about this pen? It's only 20 yuan — cheap enough! A: Great, I'll take it.
考场提分提醒听力里店员一说 Can I help you，立刻竖起耳朵等顾客那句 I'm looking for...——那就是答案。顾客说 too expensive 后面一定跟着"找更便宜的"或"不买了"，这是判断对错题的高频考点。

⑪ 记忆口诀与 7 天复习计划
三句口诀
① 进店 Can I help you? 回 I'm looking for... 或 I'd like...。
② How much is 单 are 复，It costs 物作主；try on 代词放中间，try it on 别糊涂。
③ too expensive 太贵不买，cheap enough 够便宜就 take it；enough 永远跟在形容词后面跑。
