1. What is Accounting? | 什么是会计？

Accounting is the systematic process of identifying, recording, measuring, and communicating financial information about a business or an individual. Its main purpose is to help people make informed decisions. For a KS3 student, think of accounting as keeping a detailed money diary: you note every pound that comes in (income) and every pound that goes out (expenses), then organise this information so you can see how well your business is performing.

会计是识别、记录、计量和交流与企业或个人相关的财务信息的系统过程。它的主要目的是帮助人们做出明智的决策。对于 KS3 学生来说，可以把会计想象成记一本详细的流水账：你记下每一笔进账（收入）和每一笔支出（费用），然后整理这些信息，就能看出企业的经营状况如何。

Accounting helps answer questions like: Is the business making a profit? Can it pay its bills on time? What does the business own and what does it owe? These answers are important for owners, managers, lenders, and even the government. Without accounting, it would be impossible to manage a business effectively.

会计有助于回答诸如：企业是否在盈利？它能否按时支付账单？企业拥有什么，又欠着什么？这些答案对所有者、管理者、贷款方乃至政府都很重要。没有会计，就不可能有效地管理企业。

In the WJEC KS3 syllabus, you will learn about two main branches of accounting: financial accounting, which focuses on preparing reports for external users, and management accounting, which provides information for internal decision-making. At this stage, the emphasis is on mastering the basics of financial accounting, including the accounting equation and the structure of simple financial statements.

在 WJEC KS3 课程中，你将了解会计的两大分支：侧重于为外部使用者编制报告的财务会计，以及为内部决策提供信息的管理会计。在这个阶段，重点在于掌握财务会计的基础知识，包括会计等式和简单财务报表的结构。

2. The Accounting Equation | 会计等式

The accounting equation is the foundation of all bookkeeping and financial reporting. It states that a business’s assets must always equal the sum of its liabilities and owner’s equity. In its simplest form, the equation is written as:

会计等式是所有簿记和财务报告的基础。它表明一个企业的资产必须始终等于其负债与所有者权益之和。其最简单的形式写作：

Assets = Liabilities + Owner’s Equity

资产 = 负债 + 所有者权益

This relationship is true for every business, from a small market stall to a large multinational company. It exists because every pound of assets a business controls must be funded either by borrowing (liabilities) or by the owner’s own investment and retained profits (equity). If a company purchases a new computer for £800, it might use cash (an asset), so total assets drop by £800 and then increase by £800 – assets remain unchanged. If it borrows £800 to buy the computer, assets increase by £800 and liabilities increase by £800, keeping the equation balanced.

这种关系适用于每一个企业，从街边小摊到大型跨国公司。之所以存在这种关系，是因为企业控制的每一英镑资产，都必须通过借款（负债）或者所有者自身的投资及留存利润（权益）来融资。如果一家公司花 800 英镑购买一台新电脑，它可能使用现金（一项资产），因此总资产先是减少 800 英镑再增加 800 英镑——资产总额不变。如果它借入 800 英镑购买电脑，资产增加 800 英镑，同时负债增加 800 英镑，等式依然平衡。

You can rearrange the equation to highlight different perspectives. For example, Owner’s Equity = Assets – Liabilities. This tells you what the business is worth to the owner after settling all debts. In WJEC KS3, you will practise identifying whether a transaction increases or decreases assets, liabilities, or equity, always ensuring the equation stays in balance.

你可以重新排列等式来突出不同的视角。例如，所有者权益 = 资产 – 负债。这告诉你，在清偿所有债务后，企业对所有者来说值多少钱。在 WJEC KS3 课程中，你将练习判断一笔交易是增加了还是减少了资产、负债或权益，并始终确保等式保持平衡。

3. Assets, Liabilities, and Equity | 资产、负债和所有者权益

Understanding the three elements of the accounting equation is essential. An asset is a resource controlled by the business as a result of past events, from which future economic benefits are expected to flow. Typical assets include cash at bank, inventory (goods for resale), equipment, vehicles, and land and buildings. Intangible assets like trademarks and patents also count, though you are unlikely to see them at KS3.

理解会计等式的三个要素至关重要。资产是指由企业因过去事项而控制的资源，预期将从中流入未来经济利益。典型的资产包括银行存款、存货（待售商品）、设备、车辆以及土地和建筑物。像商标和专利这类无形资产也算在内，不过在 KS3 阶段你不太会接触到。

A liability is a present obligation of the business arising from past events, the settlement of which is expected to result in an outflow of resources. Common liabilities are trade payables (money owed to suppliers), bank overdrafts, loans, and accrued expenses. Liabilities represent claims on the business’s assets by outsiders, such as banks and suppliers.

负债是指因过去事项而形成的企业现时义务，履行该义务预期会导致资源流出。常见的负债包括应付账款（欠供应商的钱）、银行透支、贷款和应计费用。负债代表了外部方，如银行和供应商，对企业资产的求偿权。

Owner’s equity is the residual interest in the assets of the business after deducting all its liabilities. It is sometimes called capital or net assets. Equity increases when the owner invests more money (capital contributed) and when the business earns a profit. It decreases when the owner withdraws money (drawings) or when the business suffers a loss.

所有者权益是指企业资产扣除全部负债后的剩余利益。它有时被称为资本或净资产。当所有者投入更多资金（投入资本）以及企业赚取利润时，权益会增加。当所有者提取资金（提用）或者企业发生亏损时，权益会减少。

The table below gives typical examples you might encounter in a KS3 WJEC exercise:

下表提供了你在 KS3 WJEC 练习中可能遇到的典型例子：

Category	Examples
Asset	Cash, inventory, computers, vans
Liability	Bank loan, trade payables, mortgage
Equity	Owner’s capital, retained profits, drawings (negative effect)

4. Double-Entry Bookkeeping | 复式记账法

Double-entry bookkeeping is the method used to record every transaction in at least two accounts so that the accounting equation always stays in balance. For each transaction, a debit entry is made in one account and a corresponding credit entry is made in another. The total debits must always equal the total credits. This system was first documented by the Italian mathematician Luca Pacioli in 1494 and has remained the backbone of accounting ever since.

复式记账法是一种将每笔交易至少记录在两个账户中的方法，以确保会计等式始终保持平衡。对于每笔交易，一个账户记入借方，另一个账户对应记入贷方。借方总额必须始终等于贷方总额。这一体系由意大利数学家卢卡·帕乔利于 1494 年首次记载，此后一直是会计的支柱。

At KS3, you do not need to worry about complex rules for debits and credits just yet, but you should understand the principle: a purchase of stationery for cash involves a decrease in cash (credit) and an increase in expenses (debit). The accounting equation remains in balance because equity falls due to the expense, and assets fall because cash is used.

在 KS3 阶段，你暂时不需要为复杂的借贷规则而烦恼，但应该理解其原理：用现金购买文具涉及现金的减少（贷记）和费用的增加（借记）。会计等式保持平衡，因为费用导致权益减少，同时使用现金导致资产减少。

A simple way to remember the basic rules is to associate increases in assets with debits, increases in liabilities and equity with credits, and vice versa. The WJEC KS3 course focuses on applying these ideas to straightforward business situations rather than memorising account structures.

记住基本规则的一个简单方法是：资产的增加记借方，负债和权益的增加记贷方，反之亦然。WJEC KS3 课程的重点是将这些理念应用于简单的商业场景，而不是记忆账户结构。

5. Source Documents | 原始凭证

Before any transaction is recorded in the books, there must be a source document. A source document is the original record that provides evidence of a transaction and the amounts involved. Common examples include invoices, receipts, credit notes, cheques, and bank statements. These documents are essential for accuracy and for verifying the information when preparing financial statements.

在将任何交易记入账簿之前，必须有一份原始凭证。原始凭证是提供交易及其金额证据的最初记录。常见的例子包括发票、收据、信用票据、支票和银行对账单。这些凭证对于保持准确性以及在编制财务报表时验证信息至关重要。

Invoices are issued by a seller when goods or services are provided on credit. They show the date, details of the goods, unit prices, total amount, and payment terms. When goods are returned, a credit note is issued to reduce the amount the buyer owes. Receipts confirm payment has been made and are especially important for cash transactions.

发票由卖方在赊销商品或服务时开具。它显示日期、商品详情、单价、总金额和付款条件。当商品被退回时，会开具一张贷记通知单来减少买方的欠款。收据则确认款项已支付，对于现金交易尤为重要。

In a KS3 WJEC task, you might be asked to interpret information from a sample invoice or to identify which source document is needed for a given situation. Always remember that every accounting entry must be supported by a valid source document to maintain a clear audit trail.

在 KS3 WJEC 的任务中，你可能会被要求解读示例发票中的信息，或者识别给定情境下需要哪种原始凭证。请始终记住，每一笔会计分录都必须有有效的原始凭证作为依据，以保持清晰的审计轨迹。

6. Journals and Ledgers | 日记账和分类账

Once source documents are collected, transactions are first entered into journals and then posted to ledgers. A journal, often called the book of prime entry, records transactions in chronological order. It shows which accounts need to be debited and credited and provides a brief description. Typical journals include the sales journal, purchases journal, cash receipts journal, and cash payments journal.

收集好原始凭证后，交易首先要记入日记账，然后过账到分类账。日记账，常被称为原始分录簿，按时间顺序记录交易。它注明哪些账户需要借记和贷记，并附上简要说明。常见的日记账包括销售日记账、采购日记账、现金收入日记账和现金付款日记账。

After entries are recorded in the journal, the amounts are transferred to ledger accounts. A ledger is a collection of T-accounts, each tracking a specific asset, liability, equity, income, or expense. For example, the cash account shows all money coming in and going out, while the sales account accumulates total income from selling goods. The process of copying journal entries to the ledger is called posting.

交易在日记账中记录后，金额会被转移到分类账账户。分类账是 T 形账户的集合，每个账户追踪一项特定的资产、负债、权益、收入或费用。例如，现金账户显示所有收入的款项和支出的款项，而销售收入账户则累计销售商品的总收入。将日记账分录抄写到分类账的过程称为过账。

Although KS3 exercises may simplify these steps, it is useful to know that this orderly flow from source document → journal → ledger → trial balance is what ensures reliability. Practice writing up a simple T-account for a cash transaction to see how each entry has two sides.

尽管 KS3 的练习可能会简化这些步骤，但了解从原始凭证 → 日记账 → 分类账 → 试算平衡表这一有序的流程如何确保可靠性是很有用的。可以练习为一个现金交易填写一个简单的 T 形账户，看看每笔分录如何具有两方。

7. The Trial Balance | 试算平衡表

A trial balance is a list of all the general ledger accounts with their closing balances at a particular date, arrayed in debit and credit columns. Its main purpose is to check the arithmetical accuracy of the double-entry system: total debits should equal total credits. If they do not match, an error has occurred and must be found and corrected.

试算平衡表是一份列示特定日期所有总分类账账户及其期末余额的清单，分为借方栏和贷方栏。它的主要目的是检查复式记账系统的算术准确性：借方总额应等于贷方总额。如果两者不相符，说明出现了错误，必须找出并更正。

It is important to note that a trial balance can still balance even when some errors exist. For example, if a transaction is completely omitted, or if the same incorrect amount is posted to both sides, the trial balance will not reveal the mistake. Therefore, a balanced trial balance is a good sign but not absolute proof of accuracy.

需要注意的是，即使存在某些错误，试算平衡表仍然可能平衡。例如，如果一笔交易被完全遗漏，或者同一个错误金额同时记入了借贷双方，试算平衡表将无法揭示这个错误。因此，试算表平衡是一个好的迹象，但不是准确性的绝对证明。

At KS3 you will practise constructing a simple trial balance from a list of ledger balances. A typical exercise looks like this:

在 KS3 阶段，你将练习根据一系列分类账余额编制一份简单的试算平衡表。一个典型的练习如下表所示：

Account	Debit (£)	Credit (£)
Cash	2,500
Inventory	1,200
Trade Payables		800
Bank Loan		4,000
Capital		5,000
Sales		6,500
Rent Expense	600
Totals	4,300	16,300? (Oops – this is an imbalanced example; in a correct one totals match)

In reality, the totals must be equal; any discrepancy prompts you to check your work. The trial balance is the springboard for preparing the final accounts.

实际上，总额必须相等；任何不一致之处都会促使你检查自己的工作。试算平衡表是编制最终账目的跳板。

8. Income Statement (Profit & Loss) | 利润表（损益表）

The income statement, also called the profit and loss account, summarises the revenue and expenses of a business over a period of time, such as a month or a year, to determine whether the business made a profit or a loss. At KS3 WJEC, you will learn the basic layout: revenue minus cost of sales equals gross profit, then other expenses are deducted to arrive at net profit.

利润表，又称损益表，汇总了企业在一个期间（如一个月或一年）内的收入和费用，以确定企业是盈利还是亏损。在 KS3 WJEC 课程中，你将学习其基本结构：收入减去销售成本等于毛利润，然后再扣除其他费用得出净利润。

The key headings are:

其关键项目有：

• Revenue (sales): total income from selling goods or services.
• 收入（销售额）：销售商品或服务获得的总收入。
• Cost of Sales: the direct costs of buying or making the goods sold. At KS3 this usually means opening inventory + purchases – closing inventory.
• 销售成本：购买或制造已售商品的直接成本。在 KS3 阶段，通常指期初存货 + 采购 – 期末存货。
• Gross Profit: revenue – cost of sales.
• 毛利润：收入 – 销售成本。
• Expenses: indirect costs like rent, salaries, advertising, and utilities.
• 费用：间接成本，如租金、工资、广告费和公用事业费。
• Net Profit: gross profit – total expenses.
• 净利润：毛利润 – 总费用。

A simple income statement can be drawn up as follows (figures in £):

一份简单的利润表可编制如下（单位为英镑）：

Item	£
Revenue	12,000
Less: Cost of Sales	(5,000)
Gross Profit	7,000
Less: Expenses	(2,800)
Net Profit	4,200

Understanding the income statement helps you see whether a business is generating enough profit to continue operating and to reward its owner. It also highlights areas where costs might need to be controlled.

理解利润表有助于你了解企业是否创造了足够的利润来持续经营并回馈其所有者。它还能凸现出可能需要控制成本的领域。

9. Statement of Financial Position (Balance Sheet) | 财务状况表（资产负债表）

The statement of financial position, commonly called the balance sheet, is a snapshot of a business’s assets, liabilities, and equity at a specific point in time. It directly reflects the accounting equation and demonstrates the financial position of the business. At KS3 WJEC, you are expected to prepare a basic balance sheet using the knowledge you have gained about the accounting equation.

财务状况表，通常称为资产负债表，是在特定时点反映企业资产、负债和权益状况的快照。它直接体现了会计等式，并展示企业的财务状况。在 KS3 WJEC 课程中，你需要运用所掌握的会计等式知识来编制一份基本的资产负债表。

The balance sheet is divided into two main sections that must always balance. One common layout lists non-current assets (those kept for more than one year, like machinery and buildings), then current assets (cash, inventory, trade receivables), then current liabilities (trade payables, overdraft) and non-current liabilities (long-term loans), followed by equity.

资产负债表分为必须始终保持平衡的两大部分。一种常见的格式是，先列出非流动资产（使用期限超过一年的资产，如机器和房屋），然后是流动资产（现金、存货、应收账款），接着是流动负债（应付账款、透支）和非流动负债（长期借款），最后是权益。

A simplified KS3 balance sheet might look like this:

一份简化的 KS3 资产负债表可能如下所示：

Assets	£	Liabilities and Equity	£
Equipment	3,000	Trade Payables	600
Inventory	1,200	Bank Loan (5 yr)	2,000
Cash	1,500	Capital	3,100
		Retained Profit	1,000
Total Assets	5,700	Total Liabilities + Equity	5,700

Notice how the left side (total assets) equals the right side (total liabilities plus equity). This is the key message of the balance sheet. It helps users decide if the business can meet its short-term obligations and how heavily it relies on borrowed money.

请注意左边（总资产）如何与右边（负债和权益总额）相等。这就是资产负债表传递的关键信息。它帮助使用者判断企业能否支付其短期债务，以及它对借款的依赖程度。

10. The Accounting Cycle Overview | 会计循环概述

All the steps we have discussed are part of a repeatable sequence called the accounting cycle. This cycle starts with transactions and ends with the preparation of financial statements. Understanding this cycle gives you a complete picture of how accounting works in practice and is a central theme in the KS3 WJEC syllabus.

我们讨论过的所有步骤都是一个可重复的序列的一部分，称为会计循环。这个循环从交易事项开始，到编制财务报表结束。理解这个循环能够让你全面了解会计在实务中是如何运作的，这也是 KS3 WJEC 课程的一个核心主题。

The main stages of the accounting cycle are:

会计循环的主要阶段包括：

• Step 1: Analyse and record transactions using source documents.
• 第一步：利用原始凭证分析并记录交易。
• Step 2: Journalise the transactions – enter them into the appropriate journal.
• 第二步：编制日记账分录——将交易记入恰当的日记账。
• Step 3: Post journal entries to the general ledger accounts.
• 第三步：将日记账分录过账至总分类账账户。
• Step 4: Prepare an unadjusted trial balance to check debits equal credits.
• 第四步：编制未调整试算平衡表，检查借方与贷方是否相等。
• Step 5: Make adjusting entries for accruals, prepayments, and depreciation (more advanced, but aware of).
• 第五步：对应计项目、预付款项和折旧等进行调整分录（较深入，但应有了解）。
• Step 6: Prepare the income statement and finally the balance sheet.
• 第六步：编制利润表，最后编制资产负债表。
• Step 7: Close the temporary accounts (revenue and expense) to get ready for the next period.
• 第七步：结清暂时性账户（收入和费用），为下一期间做准备。

At KS3 WJEC, the focus is on steps 1 to 4 and step 6, with an introduction to the idea that accounting is a systematic process. Recognising the flow makes the subject less like a set of isolated rules and more like a logical map of business activity.

在 KS3 WJEC 课程中，重点是第 1 至第 4 步和第 6 步，同时介绍会计是一个系统化过程的概念。认识这一流程会使这个学科不再像一套孤立的规则，而更像一幅合乎逻辑的商业活动地图。

Recap all these core points regularly, and practise with simple transaction examples. Over time, you will find that the language of business is not difficult to learn – it simply requires careful attention to the logic of the accounting equation and the discipline of double-entry recording.

定期回顾所有这些核心要点，并用简单的交易实例加以练习。随着时间的推移，你会发现这门商业的语言并不难学——它只需要你细心关注会计等式的逻辑和复式记录的严谨性。
