Before we dive into the questions, remember that in Business Studies, using correct terminology is essential. Even if your idea is correct, vague language can lose marks. Always aim to be precise and, where possible, support your points with simple examples.
在开始解答之前，请记住，在商务学习中，使用正确的术语至关重要。即使想法正确，模糊的语言也会导致失分。始终力求精准，并尽可能用简单的例子佐证你的观点。
2. Question 1: Defining a Business | 问题 1：定义企业
Question: What is a business? Give one example of a business that produces goods and one that provides services. (3 marks)
问题：什么是企业？分别举出一个生产商品的企业和一个提供服务的企业例子。（3 分）
A business is an organisation that uses factors of production to create goods or services that satisfy consumers’ wants and needs, usually with the aim of making a profit. Goods are tangible items you can touch, such as a smartphone or a loaf of bread. Services are intangible acts that are done for you, such as haircuts or transport. An example of a goods-producing business is a car manufacturer. An example of a service-providing business is a dentist.
企业是利用生产要素创造满足消费者欲望和需求的商品或服务，并以此盈利的组织。商品是可以触摸的有形物品，如智能手机或一条面包。服务是为你完成的无形行为，如理发或交通。生产商品的企业例子：汽车制造商。提供服务的企业例子：牙医诊所。
Common mistake: Many students lose marks by giving examples that do not clearly distinguish between goods and services. For instance, a restaurant provides both goods (food) and services (serving), so it’s better to use a clear-cut service like a cinema or a cleaning company to avoid confusion.
常见错误：许多学生因举例未能清晰区分商品和服务而失分。例如，餐厅同时提供商品（食物）和服务（侍应），因此最好使用电影院或清洁公司这样界限分明的服务类例子，以避免混淆。
3. Question 2: Needs and Wants | 问题 2：需要与欲望
Question: Distinguish between a ‘need’ and a ‘want’. Provide one example of each. (3 marks)
问题：区分“需要”与“欲望”，并各举一例。（3 分）
A need is something essential for human survival, such as food, water, shelter, and basic clothing. A want is a desire for a product or service that is not necessary for survival but improves quality of life or status, such as a designer handbag or a video game console. For example, drinking water is a need, while a bottle of premium sparkling water is a want.
需要是人类生存所必需的物品，如食物、水、住所和基本衣物。欲望是对非生存必需但能提升生活质量或地位的产品或服务的渴求，例如名牌手袋或游戏机。举例：饮用水是需要，而一瓶高级气泡矿泉水则是欲望。
Understanding this distinction helps explain how businesses create and shape wants through advertising and branding. A need for warmth might be satisfied by a basic coat, but marketing can turn it into a want for a designer coat with a luxury logo. In your answer, be specific: ‘food’ is a need, but ‘a meal at a five-star restaurant’ is a want.
理解这一区别有助于解释企业如何通过广告和品牌塑造来创造并改变欲望。保暖这一需要可通过一件基础外套满足，但营销可能将其转化为对带奢侈品牌标志的时装外套的欲望。回答时务必具体：“食物”是需要，但“五星级餐厅的一顿饭”则是欲望。
4. Question 3: Factors of Production | 问题 3：生产要素
Question: Name the four factors of production and give an example of each for a bakery business. (4 marks)
问题：列出四个生产要素，并为一个面包店业务分别举例。（4 分）
The four factors of production are land, labour, capital, and enterprise. In a bakery:
四个生产要素是土地、劳动力、资本和企业家精神。在一家面包店中：
- Land includes natural resources such as the bakery premises and the wheat used for flour.
- Labour is the human effort provided by bakers, assistants, and delivery staff.
- Capital covers man-made resources used in production, like ovens, mixing machines, and display counters.
- Enterprise is the entrepreneur who organises the other three factors, takes risks, and makes decisions—here, the bakery owner.
- 土地：包括面包店场地、用于面粉的小麦等自然资源。
- 劳动力：面包师、店员和送货人员提供的人力。
- 资本：用于生产的人造资源，如烤箱、搅拌机和陈列柜。
- 企业家精神：组织其他三要素、承担风险并决策的企业家——此处即面包店店主。
Revise the reward associated with each factor: land earns rent, labour earns wages/salaries, capital earns interest, and enterprise earns profit. Examiners sometimes ask a follow-up question linking factor to reward, so this knowledge can earn you an extra mark.
复习各要素对应的回报：土地获得地租，劳动力获得工资/薪水，资本获得利息，企业获得利润。考官有时会追问要素与回报的关联，掌握这点可帮你多得一分的保险。
5. Question 4: Sole Trader Advantages and Disadvantages | 问题 4：个体经营者的优缺点
Question: Explain one advantage and one disadvantage of operating as a sole trader. (4 marks)
问题：解释作为个体经营者运营的一个优点和一个缺点。（4 分）
Advantage: A sole trader keeps all the profits after tax and has full control over business decisions. There is no need to consult partners or shareholders, so decisions can be made quickly. Disadvantage: The owner has unlimited liability. This means that if the business fails, the owner is personally responsible for all debts and may lose personal assets such as a car or house.
优点：个体经营者保留全部税后利润，并对业务决策拥有完全控制权。无需与合伙人或股东协商，因此决策迅速。缺点：所有者承担无限责任。这意味着一旦企业失败，个人需对所有债务负责，并可能失去汽车或房产等个人资产。
In Year 8, you are also expected to know other types of business organisation such as partnerships and limited companies, but sole trader is the most straightforward. When writing your answer, use the exact phrase ‘unlimited liability’—this technical term is a clear signal to the examiner that you understand the risk involved.
在 Year 8 阶段，你还需了解合伙企业和有限责任公司等其他组织形式，但个体经营者是最简单的一种。作答时一定要使用“无限责任”这一确切的术语——这个专业词汇能向考官清楚表明你理解其中风险。
6. Question 5: Importance of Market Research | 问题 5：市场调研的重要性
Question: Why is market research important for a new business? Suggest one primary research method. (3 marks)
问题：为什么市场调研对新企业很重要？请提出一种一手调研方法。（3 分）
Market research reduces the risk of business failure by gathering information about potential customers, their preferences, and competitors. For a new business, it helps identify whether there is sufficient demand, what price customers are willing to pay, and how to position the product. Primary research involves collecting original data directly. One method is conducting face-to-face questionnaires with people in the target market, providing first-hand, specific feedback.
市场调研通过收集关于潜在客户、客户偏好和竞争对手的信息，降低了企业失败的风险。对新企业而言，它有助于判断是否存在足够需求、客户愿意支付的价格以及如何定位产品。一手调研指直接收集原始数据。其中一种方法是对目标市场人群进行面对面问卷调查，从而获得第一手、有针对性的反馈。
Do not confuse primary research (new data collected by the business itself) with secondary research (using existing data like government reports). For full marks, you must name a primary method and briefly explain how the business would use it, not just list the method.
切勿混淆一手调研（企业自行收集的新数据）与二手调研（使用政府报告等已有数据）。要获得满分，你必须说出一手调研方法并简要说明企业将如何使用，而非仅列出方法名称。
7. Question 6: The Marketing Mix (4Ps) | 问题 6：营销组合（4P）
Question: Identify the four elements of the marketing mix and state how a new soft drink company could use ‘Promotion’. (4 marks)
问题：指出营销组合的四个要素，并说明一家新成立的软饮料公司可以如何运用“促销”要素。（4 分）
The marketing mix consists of Product, Price, Place, and Promotion—often called the 4Ps. For a new soft drink company, promotion could involve launching an energetic social media campaign on platforms like Instagram and TikTok, targeting teenagers and young adults. They could also give away free samples at shopping centres to encourage trial and word-of-mouth, and collaborate with fitness influencers to position the drink as a healthy lifestyle choice.
营销组合包括产品、价格、地点和促销，通常称为 4P。对于一家新软饮料公司，促销可包括在 Instagram 和 TikTok 等平台开展充满活力的社交媒体活动，瞄准青少年和年轻成年人。他们还可以在购物中心免费派发样品以鼓励试用和口碑传播，并与健身达人合作，将饮品定位为健康生活方式的选择。
Examiners reward answers that connect the promotion strategy to a specific target market. So, rather than simply stating ‘advertising’, explain what kind of advertising and why it appeals to the intended customers. Also, always list all four elements even if the question only asks about one—this demonstrates full knowledge.
将促销策略与特定目标市场相联系的回答会得到考官青睐。因此，不要只说“广告”，而要解释广告类型及其吸引目标客户的原因。此外，即使题目只问一个要素，也要列出全部四个要素——这展示了你完整的知识储备。
8. Question 7: Calculating Profit | 问题 7：计算利润
Question: A business sells 200 units at $5 each. Total costs are $650. Calculate the profit. Show your working. (3 marks)
问题：某企业以单价 5 美元销售 200 件产品。总成本为 650 美元。计算利润，并写出计算步骤。（3 分）
Total Revenue = Selling Price × Quantity = $5 × 200 = $1000
Profit = Total Revenue − Total Costs = $
