1. Welcome to Accounting: Your Journey Begins | 欢迎来到会计世界：你的旅程开始了
Accounting is often called the ‘language of business’ because it tells the financial story of an organisation. Through a system of recording, classifying and summarising money-related events, accounting helps owners, managers and investors understand whether a business is performing well or struggling. Far from being just about adding up receipts, accounting provides the evidence needed to make smart decisions about pricing, spending and growth.
会计常被称为“商业的语言”，因为它讲述一个组织的财务故事。借助一套记录、分类和汇总货币事件的系统，会计能帮助所有者、管理者和投资者了解一家企业是在蓬勃发展，还是在苦苦挣扎。它绝不仅仅是把收据加起来那么简单，会计为定价、支出和增长等明智决策提供了所需的数据支撑。
In Year 9, you do not need to be a maths genius; you simply need curiosity and the willingness to think logically. The subject builds on real-life scenarios — a school tuck shop, a mobile phone retailer, or a local sports club — so you will quickly see how the rules apply to the world around you. Your first task is to start noticing the financial questions embedded in everyday life: ‘How much profit did that lemonade stand make?’, ‘Where did the money to buy new football kits come from?’
在 Year 9 阶段，你不需要成为数学天才，只需要有好奇心和逻辑思考的意愿。这门学科建立在真实的生活场景之上——学校的小卖部、手机零售店或本地体育俱乐部——因此你很快就会发现这些规则如何应用于身边的世界。你的第一个任务是开始留意日常生活中隐含的财务问题：“那个柠檬水小摊赚了多少利润？”“购买新足球装备的钱是从哪里来的？”
Accounting also rewards careful attention to detail. Small errors, such as recording an amount in the wrong column, can change the whole picture. Treat this preview as your chance to build habits of accuracy right from the start.
会计还格外看重对细节的关注。小错误——比如把金额记错了栏——会改变整个财务图景。把这次预习当作从一开始就养成准确性习惯的好机会。
2. What is Accounting and Why Does It Matter? | 什么是会计，它为何重要？
At its core, accounting is a process of identifying, measuring and communicating economic information to allow informed judgements and decisions. Accountants do not simply count cash; they interpret what the numbers mean. For example, a drop in sales might be recorded as a number, but an accountant investigates whether it was caused by a competitor, a change in customer taste or seasonal factors.
会计在本质上是一个识别、衡量和传递经济信息的过程，目的是让人们做出有依据的判断和决策。会计师并不只是数现金，他们还要解读数字背后的含义。例如，销售额的下降可能体现为一个数字，但会计师会探究其原因究竟是竞争对手的冲击、消费者口味的变化还是季节因素的影响。
The discipline splits broadly into two branches. Financial accounting focuses on producing statements for people outside the business — like banks, suppliers and shareholders. Management accounting, meanwhile, generates reports for insiders — such as department heads — to help plan and control operations. In Year 9, we will concentrate on the foundations that serve both branches, starting with the most famous tool in the accountant’s kit: the accounting equation.
这门学科大致分为两个分支。财务会计侧重为外部人士——如银行、供应商和股东——编制报表；而管理会计则为内部人员——比如部门主管——制作报告，以协助规划和控制经营活动。在 Year 9，我们将集中学习对两个分支都有用的基础知识，就从会计师工具箱中最著名的工具——会计等式——开始。
Understanding why accounting matters also means appreciating its role in accountability. Whenever anyone handles money on behalf of others — be it a charity treasurer or a company director — accounting records provide a transparent trail that shows how every pound was raised and spent. This is why accounting is often described as the foundation of trust in business.
理解会计为何重要，还意味着认识到它在问责中的角色。每当有人代表他人处理资金时——无论是慈善机构的财务主管，还是公司董事——会计记录都能提供一条透明的轨迹，展示每一英镑是如何筹集和支出的。正因如此，会计常被形容为商业信任的基石。
3. The Fundamental Accounting Equation | 基本会计等式
Everything in financial accounting rests on one simple equation that must always balance:
财务会计的一切都建立在一个必须永远保持平衡的简单等式之上：
Assets = Liabilities + Owner’s Equity
This equation tells us that everything the business owns (assets) has been financed either by borrowing from outsiders (liabilities) or by the owner’s own contribution and accumulated profits (equity). No matter how complex a multinational corporation becomes, its balance sheet will always obey this rule. Think of it like a set of scales: the left side must always equal the right side.
这个等式告诉我们，企业所拥有的一切（资产）要么是通过向外部借款（负债）融资得来的，要么是通过所有者的自有投入以及累积利润（所有者权益）融资得来的。无论一家跨国公司的规模多么庞大、结构多么复杂，其资产负债表永远遵循这条规则。你可以把它想象成一台天平：左边必须始终等于右边。
For a brand-new business, the equation often starts with the owner putting in cash. If Maria pays £5,000 into her business bank account, the firm has an asset of £5,000 (cash) and the owner’s equity also stands at £5,000. If Maria then borrows £2,000 from a bank, assets jump to £7,000, but now liabilities of £2,000 appear, leaving equity unchanged at £5,000. Notice how the two sides remain equal.
对于一家新成立的企业，等式通常始于所有者投入现金。假如玛利亚将 5,000 英镑存入企业的银行账户，该公司就拥有一项 5,000 英镑的资产（现金），同时所有者权益也是 5,000 英镑。如果玛利亚随后从银行借款 2,000 英镑，资产增加到 7,000 英镑，但此时会产生 2,000 英镑的负债，权益保持 5,000 英镑不变。注意，等式的两边依然相等。
You will encounter many variations of this equation, such as:
你还会遇到这个等式的多种变体，比如：
Assets − Liabilities = Owner’s Equity
This rearranged form helps you see that the owner’s claim on the business is what remains after all debts are paid. Keeping the equation in balance is the single most important discipline in bookkeeping.
这一变形可以帮你看到，所有者在企业中的求偿权，正是清偿全部债务之后剩下的部分。保持等式的平衡，是簿记工作中最重要的一条纪律。
4. Understanding Assets | 理解资产
An asset is a resource controlled by the business as a result of past events, from which future economic benefits are expected to flow. In plain English, it is something valuable that the business owns or has a right to use. Assets can take many forms: physical items like buildings, vehicles and inventory, or non-physical items like money owed by customers (trade receivables) and bank balances.
资产是指由于过去的事项而由企业控制的、预期会导致未来经济利益流入的资源。用通俗的话说，就是企业拥有或有权使用的、有价值的东西。资产的形式多种多样：既可以是建筑物、车辆和存货这样的实物，也可以是像客户欠款（应收账款）和银行存款余额这样的非实物形态。
Accountants usually divide assets into two categories. Non-current assets (sometimes called fixed assets) are those intended for long-term use — for example, a delivery van expected to serve the business for several years. Current assets, by contrast, are expected to be turned into cash or used up within a year; stock (inventory), trade receivables and cash itself all fall into this group. This distinction helps readers of financial statements understand the liquidity — how quickly assets can be converted into cash — of the business.
会计师通常将资产分为两类。非流动资产（有时也称固定资产）是那些准备长期使用的项目，比如一辆预计为企业服务数年的送货面包车。而流动资产则预计在一年内变现或被耗用；存货（库存）、应收账款和现金本身都属于这一类。这种区分有助于财务报表读者了解企业的流动性，也就是资产转换为现金的速度。
When learning to identify assets, ask yourself three questions: Does the business control it? Did it arise from a past transaction? Will it probably bring future benefit? If the answer to all three is ‘yes’, you are looking at an asset.
在学习识别资产时，问自己三个问题：企业是否控制着它？它是否源于过去的交易？它是否很可能带来未来的收益？如果三个问题的答案都是“是”，那么你面对的很可能就是一项资产。
5. Understanding Liabilities and Owner’s Equity | 理解负债和所有者权益
Liabilities represent present obligations of the business arising from past events, the settlement of which is expected to result in an outflow of resources. Simply put, they are debts that the firm must eventually pay. Examples include bank loans, amounts owed to suppliers (trade payables) and accrued expenses such as unpaid electricity bills.
负债代表企业因过去事项而产生的现时义务，履行该义务预期会导致含有经济利益的资源流出。简单来说，负债就是企业最终必须偿还的债务。例子包括银行贷款、对供应商的欠款（应付账款）以及像未结清的电费这类应计费用。
Like assets, liabilities are split between non-current and current. Non-current liabilities are debts that do not need to be repaid within the next year, such as a five-year bank loan. Current liabilities are those due within twelve months — a supplier waiting to be paid in 30 days, or the upcoming instalment of a loan. The balance between current assets and current liabilities is a key measure of a business’s short-term health.
与资产类似，负债也分为非流动负债和流动负债。非流动负债是那些不需要在接下来一年内偿还的债务，比如一笔五年期的银行贷款。流动负债则是在十二个月内到期的债务——比如要求在 30 天内付款的供应商欠款，或者即将到期的一笔贷款分期还款额。流动资产与流动负债之间的平衡，是衡量企业短期健康状况的关键尺度。
Owner’s equity, the other side of the equation, represents the owner’s residual interest in the assets after deducting all liabilities. For a sole trader, it often starts with the capital introduced by the owner and grows through profits earned and retained in the business, less any drawings taken out for personal use. If the business is successful, equity rises over time; if it makes persistent losses, equity can dwindle and even become negative.
等式的另一端是所有者权益，它代表在扣除所有负债以后，所有者对资产享有的剩余利益。对于个体经营者来说，权益通常始于所有者投入的资本，并随着企业赚取和留存的利润而增加，但要减去提取用于个人消费的“提款”。如果企业经营成功，权益会随时间推移而增长；如果持续亏损，权益可能萎缩，甚至变成负数。
6. Introducing Revenue and Expenses | 介绍收入和费用
Revenue (often called sales or turnover) is the income generated from the ordinary activities of a business, such as selling goods or providing services. Importantly, revenue is recorded when it is earned, not necessarily when cash is received. If a graphic designer completes a project in June but the client pays in July, the revenue belongs to June’s records under the accruals concept.
收入（常被称为销售额或营业收入）是指企业从日常活动中产生的收益，例如销售商品或提供服务。关键的一点是，收入是在赚取之时就予以记录，而不是在实际收到现金时。如果一名平面设计师在六月完成了一个项目，但客户七月才付款，那么按照权责发生制概念，这笔收入应归属于六月的记录。
Expenses represent the costs incurred in earning that revenue. Think of rent, wages, electricity, and the cost of goods sold. The matching principle states that expenses should be matched to the same period as the revenue they helped to generate. This ensures that a profit figure genuinely reflects the effort and resources consumed during that time, rather than being distorted by when bills happen to be paid.
费用则代表为赚取上述收入而发生的成本。想想租金、工资、电费以及已售商品的成本。配比原则要求，费用应当与它们帮助产生的收入归属到同一期间。这能确保利润数字真实地反映当期所消耗的努力和资源，而不至于被账单恰好何时支付所扭曲。
The relationship between revenue and expenses gives us the profit equation:
收入和费用之间的关系为我们提供了利润等式：
Profit = Revenue − Expenses
When revenue exceeds expenses, the business makes a profit, which increases owner’s equity. When expenses exceed revenue, a loss occurs, reducing equity. This direct link back to the accounting equation is what keeps the whole system integrated.
当收入超过费用时，企业就实现了利润，这会增加所有者权益。当费用超过收入时，就会发生亏损，从而减少权益。这种与会计等式的直接联系，使整个系统浑然一体。
7. The Double-Entry System: Debits and Credits | 复式记账系统：借方与贷方
Every transaction affects at least two accounts, and the double-entry system ensures the accounting equation always remains in balance. The terms ‘debit’ and ‘credit’ simply refer to the left side and right side of an account. They do not inherently mean good or bad; they are directional labels. Learning to apply them correctly is like learning the grammar of accounting.
每一项交易都至少会影响两个账户，而复式记账系统能确保会计等式始终保持平衡。“借方”和“贷方”这两个术语仅仅分别指代账户的左方和右方。它们本身并不蕴含好或坏的意思，只是方向性的标签。学会正确运用它们，就像学习会计的语法一样。
The rules can be memorised through the following principles. Assets increase on the debit side and decrease on the credit side. Liabilities and equity behave in the opposite way: they increase on the credit side and decrease on the debit side. Because revenue adds to equity, revenue accounts increase with a credit entry, while expenses — which reduce equity — increase with a debit entry. A popular mnemonic is DEAD CLIC: Debit Expenses, Assets and Drawings; Credit Liabilities, Income and Capital.
这些规则可以通过以下原则来记忆。资产在借方增加，在贷方减少。负债和权益则相反：它们在贷方增加，在借方减少。由于收入会使权益增加，所以收入账户以贷方记录增加；而费用会减少权益，因此费用账户以借方记录增加。一个流行的记忆口诀是“DEAD CLIC”（借费用、资产和提款；贷负债、收入和资本）。
Imagine a business buys stationery for £30 in cash. Two accounts are affected: stationery (an expense) increases by £30, so we debit the expense account. Cash (an asset) decreases by £30, so we credit the cash account. The total debits equal the total credits, preserving balance. Every single transaction you record will follow this pattern.
想象一家企业用现金购买了 30 英镑的文具。这里有两个账户受到影响：文具（一项费用）增加了 30 英镑，因此我们借记费用账户；现金（一项资产）减少了 30 英镑，因此我们贷记现金账户。借方总额等于贷方总额，平衡得到保持。你记录的每一笔交易都将遵循这一模式。
8. Recording Simple Transactions | 记录简单的交易
Let us practise transaction analysis with a handful of everyday examples. For each one, identify the two accounts involved, determine whether each is increasing or decreasing, and then apply the debit and credit rules. This exercise builds the muscle memory you will need throughout your accounting studies.
让我们通过几个日常例子来练习交易分析。对每一笔交易，找出所涉及的两个账户，判断每个账户是增加还是减少，然后运用借贷规则进行记录。这项练习能建立起你在整个会计学习过程中都将用到的“肌肉记忆”。
Transaction 1: Owner invests £10,000 cash into the business. Cash (asset) increases — debit Cash. Capital (equity) increases — credit Capital.
交易 1：所有者向企业投入现金 10,000 英镑。现金（资产）增加——借记现金。资本（权益）增加——贷记资本。
Transaction 2: Business buys a laptop for £800 using a bank loan. Equipment (asset) increases — debit Equipment. Bank loan (liability) increases — credit Bank loan.
交易 2：企业用银行贷款购买了一台笔记本电脑，价值 800 英镑。设备（资产）增加——借记设备。银行贷款（负债）增加——贷记银行贷款。
Transaction 3: Business provides services and immediately receives £500 cash. Cash (asset) increases — debit Cash. Service revenue (income) increases — credit Service revenue.
交易 3：企业提供服务并立即收到 500 英镑现金。现金（资产）增加——借记现金。服务收入（收入）增加——贷记服务收入。
Transaction 4: Business pays £200 rent in cash. Rent expense (expense) increases — debit Rent expense. Cash (asset) decreases — credit Cash.
交易 4：企业用现金支付 200 英镑租金。租金费用（费用）增加——借记租金费用。现金（资产）减少——贷记现金。
Writing these entries out repeatedly will help you internalise the logic. Notice how every set of entries has at least one debit and one credit, and the total debits always equal the total credits. This is your proof that the accounting equation remains intact.
反复书写这些分录将帮助你内化其中的逻辑。注意，每一组分录至少有一个借方和一个贷方，并且借方总额永远等于贷方总额。这就是会计等式始终保持不变的证明。
9. An Introduction to the Income Statement | 利润表入门
The income statement (sometimes called the profit and loss account) summarises a business’s revenue and expenses over a period of time, such as a month or a year. Its purpose is to calculate the profit or loss generated. The structure is logical: revenue comes first, then the costs directly linked to making sales are deducted to arrive at gross profit, and finally other operating expenses are subtracted to yield net profit.
利润表（有时也称为损益表）汇总了一段时期——例如一个月或一年——内企业的收入和费用。它的目的是计算出所产生的利润或亏损。其结构十分合乎逻辑：最上面是收入，接着扣除与销售直接相关的成本以得出毛利润，最后再减去其他营业费用，得到净利润。
Consider a simple example. A market stall generated £5,000 in sales revenue during the month. The cost of the goods it sold was £3,000. The stall also paid £500 for pitch rental and £200 for other sundry expenses. The income statement would show:
举一个简单的例子。某市场摊位在一个月内创造了 5,000 英镑的销售收入。已售商品的成本为 3,000 英镑。该摊位还支付了 500 英镑的摊位租金以及 200 英镑的其他杂项费用。利润表将显示：
Revenue £5,000 − Cost of Sales £3,000 = Gross Profit £2,000
Gross Profit £2,000 − (Pitch Rental £500 + Sundry Expenses £200) = Net Profit £1,300
This bottom-line figure is what adds to the owner’s equity.
这个底线数字就是增加所有者权益的金额。
From a Year 9 perspective, you should become comfortable with the vocabulary — sales, cost of sales, gross profit, expenses, net profit — and the idea that the income statement tells a story of trading performance over time.
从 Year 9 的角度看，你应该熟悉这些词汇——销售额、销售成本、毛利润、费用、净利润——并明白利润表讲述的是一段时间内经营表现的故事。
10. An Introduction to the Statement of Financial Position (Balance Sheet) | 财务状况表（资产负债表）入门
While the income statement covers a period, the statement of financial position (balance sheet) captures a business’s financial position at a single point in time. It lists what the business owns (assets) and what it owes (liabilities), with the difference being the owner’s equity. The balance sheet is a direct expression of the accounting equation.
利润表覆盖的是一段时期，而财务状况表（资产负债表）则捕捉企业在某一特定时点的财务状况。它列示出企业拥有的东西（资产）和欠下的东西（负债），两者的差额就是所有者权益。资产负债表是会计等式的直接体现。
A typical layout lists non-current assets first, such as equipment and vehicles, followed by current assets such as inventory, trade receivables and cash. Current liabilities are subtracted from current assets to show net current assets (or working capital), which is then added to non-current assets. Finally, non-current liabilities are deducted and the figure for net assets is arrived at, which equals the owner’s equity section showing capital and retained profit.
典型的布局首先列出非流动资产，如设备和车辆，接着列出存货、应收账款和现金等流动资产。从流动资产中减去流动负债，得出流动资产净额（或营运资金），然后将其加上非流动资产。最后扣除非流动负债，得到净资产数字，这个数字等于所有者权益部分显示的资本和留存利润。
Even before you learn the precise format, try to see the balance sheet as a photograph of the business’s resources and claims at a given moment. If the business paused all activity on 31 December and you took a financial snapshot, the balance sheet is what that snapshot would look like.
即使在你学习确切的格式之前，也可以试着把资产负债表看作是对企业在某一给定时刻的资源与求偿权的“快照”。如果企业在 12 月 31 日暂停所有活动，而你拍下一张财务快照，资产负债表就是这张快照所呈现的样子。
11. Key Accounting Concepts and Conventions | 关键会计概念和惯例
Accounting is built upon a set of agreed concepts that make financial statements reliable and comparable. Five key ideas are particularly relevant for Year 9 students. The ‘business entity’ concept states that the business’s transactions must be kept separate from the owner’s personal dealings. Even if the owner and the business share the same bank account in daily life, for accounting purposes we imagine a wall between them.
会计建立在一套公认概念之上，这些概念使财务报表变得可靠且可比。对于 Year 9 学生来说，有五个关键理念尤为重要。“企业主体”概念指出，企业的交易必须与所有者的个人事务区分开来。即使在日常生活中，所有者与企业共用同一个银行账户，在会计上我们也要在两者之间想象一堵墙。
The ‘going concern’ concept assumes the business will continue operating for the foreseeable future unless there is evidence to the contrary. This justifies spreading the cost of expensive equipment over several years rather than treating it as a one-off expense. ‘Accruals’ tells us to record income and expenses when they are earned or incurred, not when cash changes hands. ‘Prudence’ means we should never overstate assets or income, nor understate liabilities or expenses — we prepare for the worst while hoping for the best. Finally, ‘consistency’ requires that once a business chooses a method (for example, a way of measuring inventory), it should stick with it so that results can be compared year on year.
“持续经营”概念假定，除非有相反证据，企业将在可预见的未来继续运行下去。这就为将昂贵设备的成本分摊到数年而非一次性作为费用处理提供了理由。“权责发生制”告诉我们，要在收入和费用赚取或发生之时进行记录，而不是在现金易手时记录。“谨慎性”意味着我们永远不应高估资产或收入，也不应低估负债或费用——我们抱最好的希望，但做最坏的准备。最后，“一致性”要求企业一旦选择了一种方法（例如计量存货的方法），就应当持续使用，以便各年度的结果可以相互比较。
These concepts are not abstract theories; they are the invisible guardrails that keep financial reporting honest. Whenever you face an unfamiliar transaction, returning to these principles will guide your judgement.
这些概念并非抽象的理论；它们是保持财务报告诚实可靠的隐形护栏。每当你面对一笔陌生的交易时，回到这些原则上来，它们会为你的判断提供指引。
12. Summer Challenge: Try It Yourself | 暑期挑战：自己动手试试
The best way to cement your understanding is to practise with tiny, real-world scenarios. Set up a simple spreadsheet or notebook and record the following events for a fictional business — ‘Leo’s Gardening Services’ — for one month. Treat each step as a double-entry problem and, at the end, see if you can extract a basic income statement and a balance sheet.
巩固理解的最佳方式是用真实的微型场景进行练习。创建一个简单的电子表格或笔记本，为一家虚构企业——“利奥园艺服务”——记录一个月的下列事项。把每一步都当作一个复式记账问题来处理，并在月末看看能否提炼出一份基本的利润表和资产负债表。
Scenario: On 1 July, Leo pays £2,000 of his own money into the business bank account. On 3 July, the business buys a second-hand mower for £300 cash and a leaf blower for £100, also cash. On 10 July, Leo completes three gardening jobs and invoices customers £450 in total; customers pay two weeks later. On 15 July, the business pays £80 for fuel. On 28 July, customers settle the £450 invoice in full. On 31 July, the business pays £60 for advertising leaflets.
场景设定：7 月 1 日，利奥将 2,000 英镑
