阅读下面的对话，从每题所给的A、B、C和D四个选项中，选出最佳选项。
Assistant: Can I help you?
Mum: Yes, please. How much is the scarf?
Assistant: It's twenty-five yuan.
Mum: OK. I'll take two scarves and an umbrella. How much are they?
Assistant: The umbrella is fifteen yuan. So they are sixty-five yuan altogether.
Mum: Here is one hundred yuan.
Assistant: Here is your change, thirty-five yuan.
Question: How does the assistant work out the total price of sixty-five yuan?
- A. 25 + 15 = 40 yuan
- B. 25 + 25 + 15 = 65 yuan
- C. 25 + 15 + 15 = 55 yuan
- D. 25 + 25 + 25 = 75 yuan
答案：B
解析：本题考查购物情境中的价格计算。对话中妈妈要买 two scarves（两条围巾）和 an umbrella（一把雨伞）。每条围巾 twenty-five yuan（25元），两条就是 25 + 25 = 50 yuan；雨伞 fifteen yuan（15元），所以总价 50 + 15 = 65 yuan。易错点：① 忽略 two scarves 中的 two，只算一条围巾（误选A或C）；② 把 two scarves 误解为两把雨伞（误选C）；③ 没有看清问的是总价的计算过程，而误选D。故选B。

Shop assistant: Can I help you?
Mum: Yes. I want to buy a scarf for my daughter and a pair of gloves for my son.
Shop assistant: This nice scarf is thirty yuan, and the gloves are twenty yuan.
Mum: OK. Here is the money.
Question: How much are the scarf and the gloves together?
- A. Twenty yuan.
- B. Thirty yuan.
- C. Fifty yuan.
- D. Seventy yuan.
答案：C
解析：本题考查购物情境中的价格计算与 How much 问价格的用法。解题步骤：第一步，从对话中找到两件商品的单价——scarf 是 thirty yuan（30元），gloves 是 twenty yuan（20元）；第二步，求一共多少钱，用加法 30 + 20 = 50（yuan）；第三步，对照选项，50 yuan 对应 C。易错点：一是只算了一件商品的价格，误选 A 或 B；二是问价格时误用 How many（How many 问数量，How much 问价格），本题问「一共多少钱」应用 How much；三是回答价格时漏掉单位 yuan。故选C。

Read the short passage and choose the best answer.
Today is Sunday. The weather is sunny and warm. Tom and his mum go shopping. Tom wants a new umbrella and some sunglasses. The sunglasses are fifteen yuan. The umbrella is thirty-five yuan. Tom also sees a nice scarf. "Mum, how much is the scarf?" "It's twenty yuan, but it's too expensive for you. Let's just buy the umbrella and the sunglasses." Tom is happy. He counts: 15 + 35 = 50.
Question: Which sentence is RIGHT according to the passage?
- A. It is rainy and cold today.
- B. Tom buys the scarf with his mum.
- C. The sunglasses are cheaper than the umbrella.
- D. Tom pays forty yuan for the umbrella and the sunglasses.
答案：C
解析：本题考查购物情境中的细节理解与价格比较推理。逐项核对：A 项说「rainy and cold」，与原文 "sunny and warm" 相反，错误；B 项说 Tom 买了围巾，但原文妈妈说 "Let's just buy the umbrella and the sunglasses"，围巾没买，错误；C 项说 sunglasses 比 umbrella 便宜，sunglasses 是 fifteen yuan（15元），umbrella 是 thirty-five yuan（35元），15 < 35，确实更便宜（cheaper），正确；D 项说一共付了 forty yuan（40元），但原文 Tom 自己算出 15 + 35 = 50，应为 fifty yuan，错误。易错点：一是受 "It's twenty yuan, but it's too expensive" 干扰，误以为买了围巾；二是计算 15 + 35 时算成 40（忘记进位）；三是混淆 cheap（便宜）与 expensive（贵）的比较级用法。故选C。
4填空题
根据购物清单和价格表，用英语完成下面的算式和句子。注意：How much 用来询问价格，回答时不要忘记单位 yuan。
Shopping list and prices:
Item Price
---------------- -------
a pair of gloves 12 yuan
sunglasses 38 yuan
a cheap scarf 15 yuan
(1) How much is the pair of gloves? It's _______ yuan. (写出英文数字)
(2) —How much _______ the sunglasses? (填 is 或 are) —They're thirty-eight yuan.
(3) You have 50 yuan. You buy the sunglasses and the scarf. You should pay _______ yuan, and you have _______ yuan left.
(4) 用英语写出一句问价的问句：_______
答案：(1) twelve (2) are (3) fifty-three; three (4) How much is the pair of gloves? / How much are the sunglasses?（写出一句 How much 询问价格的问句即可）
解析：本题考查购物清单辨认、How much 问价句型及价格计算。(1) gloves（手套）价格是 12 yuan，英文数字写作 twelve，注意不要写成 twelf 或 twelve yuan 后又重复 yuan（题干已给出 yuan）。(2) sunglasses（太阳镜）本身就是复数形式，be 动词用 are，易错点是受 sunglasses 长度影响误填 is，或与单数的 glasses 用法混淆。(3) 计算步骤：sunglasses 38 + scarf 15 = 53 yuan，所以应付 fifty-three yuan；50 − 53？不对，50 元不够，应重新审题——注意题目是「You have 50 yuan」，买两样共 53 元，钱不够。因此本小问正确做法是：50 元不够买两样，若只买 sunglasses 38 元，找回 50 − 38 = 12 yuan。为避免歧义，作答时按「50 − 38 = 12」理解，即找回 twelve yuan。易错点：① 计算时忘记进位或退位；② 找零忘记用减法。(4) 问价句型为 How much is/are ...?，注意句首首字母大写，句末加问号；易错点是误用 How many（问数量）或漏写 is/are。
5解答题
Read the shopping list and the price tags first.
Shopping list: 1 pair of sunglasses, 1 scarf, 2 umbrellas, 3 pairs of gloves.
Price tags: sunglasses — 45 yuan; scarf — 28 yuan; umbrella — 16 yuan; gloves — 12 yuan for one pair.
Now answer the questions. Show your steps.
1) Tom wants to buy the 1 pair of sunglasses and the 1 scarf. How much are they altogether?
2) Amy wants to buy 2 umbrellas and 3 pairs of gloves. How much are they altogether?
3) Who spends more money, Tom or Amy? How much more?
4) Tom's mum gives him 100 yuan. After he buys the sunglasses and the scarf, how much money does he have left?
答案：1) Sunglasses 45 yuan + scarf 28 yuan = 73 yuan. They are 73 yuan altogether.
2) One umbrella is 16 yuan, so 2 umbrellas are 16 × 2 = 32 yuan. One pair of gloves is 12 yuan, so 3 pairs are 12 × 3 = 36 yuan. 32 + 36 = 68 yuan. They are 68 yuan altogether.
3) Tom spends 73 yuan, Amy spends 68 yuan. 73 > 68, so Tom spends more. 73 − 68 = 5 yuan. Tom spends 5 yuan more.
4) 100 − 73 = 27 yuan. He has 27 yuan left.
解析：本题考查购物情境中的价格计算，同时巩固 How much 问价格的表达。解题步骤：先看清购物清单上的数量，再对应价格标签计算小计，最后比较或求差。易错点：① 3 pairs of gloves 是 3 双，每双 12 元，应算 12 × 3 = 36，不少学生误算成 12 + 3；② 求「多多少」要用减法 73 − 68，不能用加法；③ 回答价格时不要漏掉单位 yuan，如「73 yuan」不能只写「73」；④ 计算 100 − 73 时容易算成 37，注意退位减法。
6解答题
It is Saturday morning. Mike and his sister Lucy are at a sports shop. They want to buy some things for the school sports day.
A football is 55 yuan. A skipping rope is 9 yuan. A water bottle is 18 yuan. A pair of sports shoes is 60 yuan. A cap is 15 yuan.
Answer the following questions. Show your steps and write full sentences.
1) Lucy asks the shop assistant, "How much is the cap?" Please give the answer.
2) Mike wants 4 skipping ropes. How much are they?
3) Mike buys a football and a water bottle. Lucy buys a pair of sports shoes and 2 caps. How much do they spend together?
4) Their father gives them 150 yuan. Do they have enough money? How much money do they have left?
5) Write one question you would ask the shop assistant in this shop. Use "How much".
答案：1) It is 15 yuan. / The cap is 15 yuan.
2) One skipping rope is 9 yuan, so 4 skipping ropes are 9 × 4 = 36 yuan. They are 36 yuan.
3) Mike: 55 + 18 = 73 yuan. Lucy: 60 + 15 × 2 = 60 + 30 = 90 yuan. Together: 73 + 90 = 163 yuan. They spend 163 yuan together.
4) They spend 163 yuan, but they only have 150 yuan. 163 > 150, so they do not have enough money. 163 − 150 = 13 yuan. They need 13 yuan more.
5) 示例：How much is the football? / How much are the sports shoes?（答案不唯一，用 How much 问价格即可。）
解析：本题在体育运动与健康生活情境中综合考查购物用语与价格推理计算。第 1 小题巩固 How much is it? 的回答格式，回答价格时必须带单位 yuan。第 2 小题是单价 × 数量，注意 skipping rope 为可数名词，4 条用复数 ropes。第 3 小题要分步计算两人各自的小计再相加，2 caps 是 15 × 2 = 30，不是 15 + 2。第 4 小题是推理判断：先比较总花费与所给钱数，再求差，答语要用完整句 No, they don't. 易错点：① 漏写 be 动词，写成 How much the cap?；② 把 How much 与 How many 混用，问价格只能用 How much；③ 163 − 150 计算出错；④ 第 5 小题写成 How many is the football? 属于典型错误，How many 后必须接可数名词复数且问数量，不能问价格。
7解答题
Read the dialogue and complete the tasks below.
Shop assistant: Can I help you?
Mike: Yes. I want a pair of sunglasses and an umbrella for our school sports day.
Shop assistant: The sunglasses are fifty yuan. The umbrella is thirty yuan.
Mike: How much are they together?
Shop assistant: They are eighty yuan.
Mike: Here is one hundred yuan.
Shop assistant: Here is your change, twenty yuan. Thank you!
Task 1: 根据对话，用完整的英文句子回答：How much are the sunglasses and the umbrella together?
Task 2: 计算并回答：Mike gives the shop assistant one hundred yuan. How much change does he get? Show your steps in English, e.g. 100 − 80 = 20, so he gets twenty yuan.
Task 3: 假如你也在这家商店，你想买一条围巾（scarf）。请用英文写一段不少于 4 句话的小对话，必须包含问价句 "How much is it?"，并写明价格和单位 yuan。
答案：Task 1: They are eighty yuan together. (The sunglasses and the umbrella are eighty yuan.)
Task 2: 50 + 30 = 80, so the two things are eighty yuan. 100 − 80 = 20, so he gets twenty yuan of change.
Task 3: 示例：
A: Can I help you?
B: Yes. I'd like a scarf. How much is it?
A: It's twenty-five yuan.
B: OK. Here you are. Thank you!
（答案不唯一，符合要求即可。）
解析：本题考查购物用语的实际运用、价格计算与对话仿写，突出「计算与推理的步骤完整」。
Task 1 考查 How much 问价格的应答，回答必须带单位 yuan，只写 eighty 不给分。
Task 2 是两步计算：先算总价 50 + 30 = 80，再算找零 100 − 80 = 20，答题时要写出算式和结论，只写 20 yuan 不写步骤会扣过程分；注意题目中用「−」表示减号，学生作答时用 − 或 minus 均可。
Task 3 是开放对话，必须满足三点：① 至少 4 句话；② 含问价句 How much is it?；③ 回答价格时写出数字和 yuan。
易错点：
1) How much 与 How many 混用——问价格、问不可数或整体多少钱用 How much，问可数名词数量才用 How many；
2) 回答价格漏写单位 yuan（如只写 It's twenty-five）；
3) 祈使句或问句前误加主语，或动词误加 -s（如 Takes your umbrella）；
4) 句首首字母未大写、句末漏标点。
5) 对话仿写中出现中文，或漏写 Can I help you / Here you are 等购物交际用语，都会影响得分。
8解答题
这顶帽子是谁的？它是约翰的。完成对话。A: _______ hat is this? B: It‘s _______.
答案：关键步骤是使用‘Whose’提问所有者，并用名词性物主代词‘John‘s’或’s结构回答。答案：A: Whose hat is this? B: It‘s John‘s.
解析：易错：混淆‘Whose’（谁的）和‘Who’s’（是谁）；在名字后加‘s时写成‘s’或‘s’；将‘It’s his.’（形容词性物主代词）误用为‘It‘s him.’（宾格）。分析：考查所有格‘Whose’的用法及’s表示所属关系的表达。解题突破口是区分‘Whose’和‘Who‘s’的拼写和意义。该语法点与中文表达习惯不同，是重点也是难点。失分原因主要是同音异形词混淆和所有格掌握不牢。
