For KS3 students following the OCR specification, understanding the core principles of accounting builds a foundation for financial literacy and future studies. This article outlines key topics, explains fundamental concepts, and provides clear examples to help you revise confidently.
会计常被称为商业的语言。对于学习OCR课程的KS3学生来说，理解会计的核心原则能为金融素养和未来学习打下基础。本文梳理了关键主题，解释了基本概念，并提供清晰示例，帮助你自信备考。
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. It helps owners, managers, and investors make informed decisions.
会计是识别、记录、计量和沟通企业财务信息的系统过程。它帮助所有者、管理者和投资者做出明智的决策。
The main purpose of accounting is to show whether a business is making a profit or a loss, what it owns, and what it owes.
会计的主要目的是反映企业是否盈利或亏损、拥有什么以及欠什么。
At KS3 level, you will learn how transactions flow from source documents into financial statements.
在KS3阶段，你将学习交易如何从原始凭证流转到财务报表。
2. The Accounting Equation | 会计等式
The accounting equation is the backbone of double-entry bookkeeping. It states:
会计等式是复式记账的基石。公式如下：
Assets = Liabilities + Owner’s Equity
资产 = 负债 + 所有者权益
Every transaction affects at least two parts of this equation, and the equation must always balance.
每笔交易至少影响这个等式的两个部分，且等式必须始终保持平衡。
For example, if a business borrows £1,000 from a bank, assets (cash) increase by £1,000 and liabilities (bank loan) also increase by £1,000. The equation stays in balance.
例如，如果企业向银行借款1,000英镑，资产（现金）增加1,000英镑，负债（银行贷款）也增加1,000英镑。等式保持平衡。
3. Assets, Liabilities and Owner’s Equity | 资产、负债和所有者权益
Assets are resources owned by a business that have future economic value. They can be current (cash, inventory) or non-current (machinery, buildings).
资产是企业拥有的、具有未来经济价值的资源。它们可以是流动的（现金、存货）或非流动的（机器、建筑）。
Liabilities are obligations or debts of the business, such as bank loans and trade payables. They are also split into current (due within one year) and non-current.
负债是企业的义务或债务，如银行贷款和应付账款。它们也分为流动负债（一年内到期）和非流动负债。
Owner’s equity represents the amount invested by the owner plus retained profits. It is the residual interest after deducting liabilities from assets.
所有者权益代表所有者投入的金额加上留存利润。它是资产扣除负债后的剩余权益。
- Current assets: cash, accounts receivable, inventory
- Non-current assets: equipment, vehicles, land
- Current liabilities: bank overdraft, creditors
- Non-current liabilities: mortgage, long-term loan
- 流动资产：现金、应收账款、存货
- 非流动资产：设备、车辆、土地
- 流动负债：银行透支、应付账款
- 非流动负债：抵押贷款、长期借款
4. Double-Entry Bookkeeping | 复式记账法
Double-entry bookkeeping means that every transaction is recorded in at least two accounts: one debit and one credit. The total debits must always equal total credits.
复式记账法意味着每笔交易至少记入两个账户：一个借方和一个贷方。借方总额必须始终等于贷方总额。
The rules are: for assets, increase is debit and decrease is credit; for liabilities and equity, increase is credit and decrease is debit. Income is recorded as credit, expenses as debit.
规则是：资产增加记借方，减少记贷方；负债和权益增加记贷方，减少记借方。收入记贷方，费用记借方。
Example: Buying a computer for £800 cash. Debit equipment (asset up) £800, credit cash (asset down) £800.
示例：用现金800英镑购买电脑。借记设备（资产增加）800英镑，贷记现金（资产减少）800英镑。
5. Ledger Accounts and T-Accounts | 分类账与T型账户
A ledger account tracks all changes to a specific item, such as ‘cash’ or ‘sales’. A T-account is a simple visual representation of a ledger account with a left side (debit) and a right side (credit).
分类账账户跟踪特定项目（如“现金”或“销售收入”）的所有变化。T型账户是分类账的简单视觉表示，左侧为借方，右侧为贷方。
Typical T-account structure:
典型的T型账户结构：
| Dr Cash Account | Cr |
| Balance b/d 500 | Rent 200 |
| Sales 1,000 | Supplies 150 |
Balancing off involves finding the difference between total debits and credits, and carrying the balance down to the next period.
结账涉及求出借方总额与贷方总额的差额，并将余额结转至下期。
6. Trial Balance | 试算平衡表
A trial balance is a list of all ledger account balances at a particular date, divided into debit and credit columns. It checks the arithmetic accuracy of the double-entry records.
试算平衡表是某一日期所有分类账账户余额的列表，分为借方栏和贷方栏。它用于检查复式记录的算术准确性。
If total debits equal total credits, the books are in balance. However, a balanced trial balance does not guarantee that there are no errors (e.g., omitted transactions or wrong amounts).
如果借方总额等于贷方总额，账簿就是平衡的。但试算平衡表平衡并不能保证没有错误（如遗漏交易或金额错误）。
Common errors that do not affect the trial balance: error of omission, commission, principle, and original entry.
不影响试算平衡表的常见错误有：遗漏错误、入错账户错误、原则性错误和原始分录错误。
7. Income Statement (Profit and Loss) | 利润表
The income statement calculates the profit or loss a business makes over a period. It follows the format: Revenue – Cost of Sales = Gross Profit; then deduct operating expenses to get Net Profit.
利润表计算企业在一段时间内的盈亏。格式为：收入 – 销售成本 = 毛利润；再扣除营业费用得出净利润。
Key components include sales revenue, opening and closing inventory, purchases, carriage inwards, and expenses like rent, wages, and advertising.
关键组成部分包括销售收入、期初和期末存货、购货、进货运费，以及租金、工资和广告费等费用。
At KS3, you will learn to prepare a simple income statement from a list of balances, remembering that inventory adjustments affect cost of goods sold.
在KS3阶段，你将学习根据余额列表编制简单的利润表，并记住存货调整会影响销售成本。
8. Statement of Financial Position (Balance Sheet) | 资产负债表
The statement of financial position shows the financial position of a business at a specific point in time. It lists assets, liabilities, and owner’s equity.
资产负债表反映企业在某一时点的财务状况。它列示资产、负债和所有者权益。
The layout is based on the accounting equation: Non-current assets + Current assets = Total assets; then show Non-current liabilities + Current liabilities, and finally Equity (capital + retained profit).
格式基于会计等式：非流动资产 + 流动资产 = 总资产；然后列示非流动负债 + 流动负债，最后是权益（资本 + 留存利润）。
It is important that the totals of the two sides match: total assets must equal total liabilities plus equity.
重要的是两边总额必须相等：总资产必须等于总负债加权益。
9. Cash Flow and Budgets | 现金流与预算
Cash flow refers to the movement of money in and out of a business. A cash flow forecast predicts future cash receipts and payments, helping to avoid liquidity problems.
现金流指资金进出企业的流动。现金流量预测表预测未来的现金收入和支出，帮助避免流动性问题。
Cash inflows may come from sales, loans, or owner investment. Cash outflows include paying suppliers, wages, and rent. The net cash flow is inflows minus outflows.
现金流入可能来自销售收入、贷款或所有者投资。现金流出包括支付供应商、工资和租金。净现金流量等于流入减去流出。
A budget is a financial plan for the future. At KS3, you may prepare simple sales budgets or expense budgets to learn how businesses control money.
预算是未来的财务计划。在KS3阶段，你可能会编制简单的销售预算或费用预算，学习企业如何控制资金。
10. Key Accounting Principles | 核心会计原则
Financial statements are prepared using several fundamental principles. These ensure consistency and reliability.
财务报表依据若干基本原则编制，以确保一致性和可靠性。
The accruals (matching) principle says that income and expenses are recorded in the period they relate to, not when cash is received or paid.
权责发生制（配比）原则规定，收入和费用应计入其归属期间，而不是现金收付时。
The going concern concept assumes that the business will continue operating in the foreseeable future. The consistency principle requires using the same accounting methods from year to year.
持续经营概念假设企业在可预见的未来继续运营。一致性原则要求年复一年使用相同的会计方法。
Prudence (conservatism) means being cautious and not overstating income or assets, while providing for all possible losses.
审慎性（稳健性）意味着要谨慎，不高估收入或资产，同时为所有可能的损失提取准备。
