📌 本单元概览与复习建议

爱心义卖开张｜课本 P19-24

本单元走进一场热闹的 学校义卖会（school fair）：孩子们摆摊义卖，为无家可归的人筹款。核心问答——How much is / are ...? / It's / They're ... dollars，问价答价学会之后，买东西就能自己开口。故事部分讲奶奶为了帮义卖会筹款，低价买进钥匙扣、翻倍卖出，再把卖到的钱全部捐给学校——会算账，更要有一颗爱心。

✦ ✦ ✦

🧩 重点语法与句型

How much is / are...? ｜ It's / They're ｜ May I have...?

2.1 核心问答：How much ...?（课本 P19-20 原对话）

问（单数）💬 How much is the watch, please?这块手表多少钱？

答（单数）💬 It's sixty-four dollars.六十四元。

问（复数）💬 How much are the crayons, please?这些蜡笔多少钱？

答（复数）💬 They're thirty-nine dollars.三十九元。

2.2 单数用 is，复数用 are：一张速记表

单数物品例词 a watch ／ the camera ／ the toy car口诀 How much is ...? → It's ...

复数物品例词 crayons ／ shoes ／ key rings ／ tickets口诀 How much are ...? → They're ...

记不准时例词先看名字有没有 -s，再看图是一件还是几件口诀一件 is，几件 are

2.3 缩写规则：四个撇号读透

It's完整形式 It is💬 It's sixty-four dollars.

They're完整形式 They are💬 They're thirty-nine dollars.

Here's完整形式 Here is💬 Here's a hundred dollars.

When's完整形式 When is💬 When's the farewell party?

2.4 礼貌购物四步（课本 P23 买票对话原句）

第一步问好💬 Excuse me.先说打扰一下，再开口问

第二步问日期💬 When's the farewell party for the headmaster? — It's on the fifteenth of July.日期前用 on

第三步问价付款💬 How much are the tickets? — They're fifty dollars each. May I have two tickets, please? Here's a hundred dollars.each 每个；Here's 给出钱

第四步道谢💬 Here you are. Thank you.接过东西别忘了谢谢

⚠️ 五个高频错误① How much 后面单数用 is、复数用 are：

❌ How much is the crayons?

✅ How much are the crayons?② dollars 的 -s 不能丢：

❌ It's sixty-four dollar.

✅ It's sixty-four dollars.③ May I have 后直接加东西：May I have two tickets，不要说 May I have to buy two tickets。④ 递东西给别人说 Here you are；Here's = Here is，用来引出钱或物：Here's a hundred dollars.⑤ 问价格开头加 Excuse me、句尾加 please，礼貌满分。

📺 对话重点理解

课本 P19-20 摆摊问答 + P23 买票对话

3.1 对话背景：义卖会摊位上

孩子们在为无家可归的人 raising money（筹款），摊位上摆着相机、手表、钱包、相框、蜡笔和鞋子。有同学指着 watch 问价，有同学指着 crayons 问价，戴帽子的风纪员一一作答。

3.2 对话原文（课本 P19-20）

男孩问台词 Excuse me. How much is the watch, please?要点指着一块手表，单数用 is

女孩问台词 How much are the crayons, please?要点指着蜡笔，复数用 are

售卖员答台词 It's sixty-four dollars. ／ They're thirty-nine dollars.要点手表 64 元；蜡笔 39 元

3.3 摊位价格速记（课本 P20 价目）

Here you are.把东西递给别人时说；接过后说 Thank you.

each「每个」，放在价格后面：They're fifty dollars each.

📖 故事重点理解

Learn to Read：奶奶义卖筹款记｜课本 P21-22

4.1 背景：奶奶怎么帮义卖会出力？

故事回答课本提出的问题 How does Grandma help at the school fair?（奶奶是怎么帮义卖会出力的？）。答案藏在数字里：5 元买进、10 元卖出、卖出的钱全捐给学校。

4.2 故事脉络：起因 → 买进 → 卖出 → 祝贺

起因关键句男孩想在义卖会上卖东西，为无家可归的人筹款，请奶奶来帮忙。Grandma, can you come to our school fair? — Sure. I can come and help you.

买进关键句奶奶在市场看到钥匙扣，每个 5 元，一口气买了 20 个。They're five dollars each. — May I have twenty, please? — Here you are.

卖出关键句义卖会上每个卖 10 元。老板带小女儿来，小女孩觉得钥匙扣很可爱，爸爸买了 3 个送给她和兄弟们。They're ten dollars each.

祝贺关键句老板夸奶奶为学校筹了很多钱。Congratulations! You're making a lot of money for the school!

4.3 课本题答案（P22：Write the correct answers）

1. 奶奶买 20 个钥匙扣，花了多少钱？答案 $100（20 × 5 = 100）

2. 小女孩的爸爸买 3 个钥匙扣，花了多少钱？答案 $30（3 × 10 = 30）

3. 奶奶卖光所有钥匙扣，卖到多少钱？答案 $200（20 × 10 = 200），全部捐给学校

4.4 读后思考（附参考答案）

奶奶为什么要买钥匙扣？答她要给义卖会准备货物，卖出筹款。

她怎么「帮」到学校？答每个 5 元买进、10 元卖出，把卖到的 200 元全部捐给学校。

小女孩为什么想买钥匙扣？答她觉得钥匙扣很可爱（She thinks the key rings are lovely.）。

为什么老板要祝贺奶奶？答因为奶奶卖光了钥匙扣，为学校筹到了很多钱。

这个故事教会我们什么？答用心出力，小小的钥匙扣也能帮到很多人。

4.5 语言点：六个值得学的写法

How does Grandma help at the school fair?How does + 主语 + 动词原形：问「怎么做的」。

raise money for the homelessraise money 为……筹款，for 引出帮助的对象。

five dollars each「每个 5 元」，each 放在价格后面。

May I have twenty, please?礼貌请求数量：May I have + 数字 + 复数名词。

spend / getspend 花费（她花 100 元买进）；get 得到、赚到（她卖到 200 元）。

You're making a lot of money现在进行时 + a lot of：正在赚很多钱。

4.6 复述支架：四句话讲完整个故事

起因A boy wants to sell things at the school fair. He asks his grandma to help.

买进Grandma buys twenty key rings at the market. They're five dollars each.

卖出At the fair, she sells them for ten dollars each. A father buys three for his children.

结尾She gets 200 dollars and gives all the money to the school. Well done!

🎧 朗读指导① five dollars each 的 each 读轻一点，突出 five dollars。② May I have twenty, please? 语调上扬，读出「有礼貌地请求」。③ Congratulations! 要读得响亮、高兴，像真的在道贺。④ 最后一句 a lot of money 稍放慢，读出「一大笔钱」的满足感。
