1. Introduction to Accounting | 会计概论
Accounting is the systematic process of recording, classifying, summarizing and interpreting financial transactions to help users make informed decisions. The main users include owners, managers, investors, lenders and tax authorities.
会计是对财务交易进行系统记录、分类、汇总和解释的过程，旨在帮助使用者做出明智决策。主要使用者包括所有者、管理层、投资者、贷款方和税务机关。
Two key branches are financial accounting, which focuses on historical reports for external users, and management accounting, which provides forward-looking data for internal decision-making. IGCSE concentrates on financial accounting.
两大分支分别是财务会计（侧重面向外部使用者的历史报告）和管理会计（为内部决策提供前瞻性数据）。IGCSE 课程主要聚焦于财务会计。
The qualitative characteristics of financial information include relevance, faithful representation, comparability, verifiability, timeliness and understandability. These ensure that reports are useful and reliable.
财务信息质量特征包括相关性、如实反映、可比性、可验证性、及时性和可理解性。这些特征确保报告有用且可靠。
2. The Accounting Equation | 会计等式
Every transaction affects the accounting equation, which must always balance:
每笔交易都会影响会计等式，该等式必须始终保持平衡：
Assets = Capital + Liabilities
Assets are resources controlled by the business, such as cash, inventory and equipment. Capital (or equity) represents the owner's investment plus retained profits. Liabilities are obligations to third parties, like trade payables and bank loans.
资产是企业控制的资源，如现金、存货和设备。资本（或权益）代表所有者的投入加上留存利润。负债是对第三方的义务，例如应付账款和银行贷款。
Transactions are analyzed using the dual-effect principle: every debit has a corresponding credit. For example, purchasing inventory for cash increases inventory (asset) and decreases cash (asset), keeping the equation balanced.
运用复式原则分析交易：每一笔借方记录都有对应的贷方记录。例如，用现金购买存货使存货（资产）增加、现金（资产）减少，等式依然平衡。
3. Double-Entry Bookkeeping | 复式记账法
The double-entry system records each transaction twice – once as a debit in one account and once as a credit in another. The rules depend on account types:
复式记账系统对每笔交易记录两次——在一个账户中记借方，在另一个账户中记贷方。规则取决于账户类型：
- Assets: increase debit, decrease credit
- Liabilities: increase credit, decrease debit
- Capital: increase credit, decrease debit
- Income: increase credit, decrease debit
- Expenses: increase debit, decrease credit
- 资产：增加记借方，减少记贷方
- 负债：增加记贷方，减少记借方
- 资本：增加记贷方，减少记借方
- 收入：增加记贷方，减少记借方
- 费用：增加记借方，减少记贷方
All transactions are first entered in books of prime entry (e.g., sales journal, purchases journal, cash book). They are then posted to the general ledger, where each account has a T-account format.
所有交易先记入原始分录簿（例如销售日记账、采购日记账、现金簿），然后过账到总分类账，每个账户采用 T 型账户格式。
A trial balance can be extracted from the ledger balances to check the arithmetic accuracy of the double-entry recordings.
可从分类账余额提取试算表，以检查复式记录的算术准确性。
4. The Trial Balance | 试算表
A trial balance is a list of all ledger account balances at a particular date, with debit balances in one column and credit balances in another. Its primary purpose is to verify that total debits equal total credits.
试算表是某一特定日期所有分类账账户余额的列表，借方余额列于一栏，贷方余额列于另一栏。其主要目的是验证借方总额等于贷方总额。
Although a balanced trial balance confirms arithmetic accuracy, it does not guarantee that the books are error-free. Errors of omission, commission, principle, compensating errors and complete reversal of entries can still exist.
虽然试算表平衡可以确认算术正确，但并不能保证账簿无误。遗漏错误、借贷方向错误、原则性错误、抵消性错误和完全颠倒分录等依然可能存在。
If the trial balance does not balance, a suspense account is opened to record the difference temporarily until the errors are located and corrected.
如果试算表不平衡，会开设一个暂记账户暂时记录差额，直至找到并纠正错误。
5. Income Statement Preparation | 利润表的编制
The income statement (or statement of profit or loss) shows the financial performance over a period. It follows this structure:
利润表（或损益表）反映某一期间的财务业绩。其结构如下：
Revenue - Cost of Sales = Gross Profit
Gross Profit + Other Income - Expenses = Profit for the Year
ases - Closing inventory. Net purchases = Purchases - Returns outwards + Carriage inwards.
销售成本计算为：期初存货 + 净购货 - 期末存货。净购货 = 购货 - 购货退出 + 购货运费。
Expenses include wages, rent, insurance, depreciation and other operating costs. It is essential to apply the accruals concept, matching expenses to the period in which they were incurred, not merely when paid.
费用包括工资、租金、保险费、折旧和其他运营成本。必须运用权责发生制概念，将费用与其发生的期间相匹配，而不仅仅是支付时。
6. Statement of Financial Position | 财务状况表（资产负债表）
The statement of financial position presents the business's assets, liabilities and capital at a point in time, following the accounting equation. It demonstrates the financial position and liquidity of the business.
财务状况表列报企业在某一时点的资产、负债和资本，遵循会计等式。它展示企业的财务状况和流动性。
Assets are classified as non-current (e.g., machinery, vehicles, fixtures) and current (e.g., inventory, trade receivables, cash). Liabilities are similarly split into non-current (long-term loans) and current (trade payables, bank overdraft).
资产分为非流动资产（如机器、车辆、装修）和流动资产（如存货、应收账款、现金）。负债同样分为非流动负债（长期贷款）和流动负债（应付账款、银行透支）。
The capital section shows the opening capital plus profit, less drawings. The balance sheet must be headed with the business name and the precise date.
资本部分列示期初资本加利润减提款。资产负债表必须在表头注明企业名称和确切日期。
7. Adjustments for Accruals and Prepayments | 应计与预付调整
The accruals (matching) concept requires that income and expenses are recognized in the period to which they relate, regardless of when cash is received or paid. This leads to adjustments for accruals (amounts owing) and prepayments (amounts paid in advance).
权责发生制（配比概念）要求收入和费用在相关期间确认，无论现金何时收付。因此需要对应计费用（欠款）和预付费用（提前支付）进行调整。
For an expense account, an accrual increases the expense and creates a current liability. A prepayment reduces the expense and creates a current asset. The adjusting entries are reflected in the income statement and statement of financial position.
就费用账户而言，应计费用增加费用并产生一项流动负债。预付费用减少费用并产生一项流动资产。调整分录反映在利润表和财务状况表中。
For example, if rent owed at year-end is £800, the rent expense in the income statement is increased by £800, and 'rent accrued' appears as a current liability. A prepayment of insurance would be deducted from the insurance expense and shown as a current asset.
例如，如果年末欠租金 800 英镑，利润表中的租金费用增加 800 英镑，同时“应付租金”列为流动负债。预付保险费将从保险费用中扣除，并作为流动资产列示。
8. Depreciation of Non-Current Assets | 非流动资产折旧
Depreciation is the systematic allocation of the cost of a non-current asset over its useful life, matching the expense against the revenue it helps generate. The two common methods are:
折旧是指将非流动资产的成本在其使用寿命内进行系统分配，将费用与其帮助产生的收入相匹配。常见的两种方法是：
- Straight-line method: Equal annual charge. Formula: (Cost - Residual value) ÷ Useful life.
- Reducing balance method: A fixed percentage is applied to the net book value each year, giving higher charges in early years.
- 直线法：每年计提等额折旧。公式：(成本 - 残值) ÷ 使用年限。
- 余额递减法：每年按固定的百分比乘以账面净值计提折旧，早年费用较高。
In the ledger, depreciation is recorded by debiting a depreciation expense account and crediting a provision for depreciation account. In the statement of financial position, the provision is deducted from the cost to show the net book value.
在分类账中，折旧的记账方式是借记折旧费用账户，贷记折旧准备账户。在财务状况表中，折旧准备从资产成本中扣除，以显示账面净值。
9. Bad Debts and Provision for Doubtful Debts | 坏账与坏账准备
A bad debt is a trade receivable that is deemed irrecoverable. When a debt is written off, the bad debts expense is debited and the trade receivable account is credited, removing it from the ledger.
坏账是指被认为无法收回的应收账款。当注销一笔坏账时，借记坏账费用账户，贷记应收账款账户，将其从分类账中移除。
The provision for doubtful debts applies the prudence concept by estimating future bad debts. An adjustment is made at year-end: the provision is increased or decreased based on the estimate (e.g., a percentage of trade receivables). Only the change in provision appears in the income statement.
坏账准备运用谨慎性概念，预估未来可能发生的坏账。年末进行调整：根据估计（例如按应收账款的一定比例）增加或减少坏账准备。只有准备的变动额计入利润表。
In the statement of financial position, the provision is deducted from trade receivables to show the estimated realizable value.
在财务状况表中，坏账准备从应收账款中扣除，以显示估计的可变现净值。
10. Bank Reconciliation | 银行存款余额调节表
A bank reconciliation statement explains the differences between the cash book balance and the bank statement balance at a particular date. Common causes include timing differences: unpresented cheques, outstanding deposits, bank charges and direct debits not yet recorded in the cash book.
银行存款余额调节表用于解释某一特定日期现金簿余额与银行对账单余额之间的差异。常见原因包括时间性差异：未兑现支票、在途存款、银行手续费以及尚未记入现金簿的直接借记等。
The reconciliation process starts from either the cash book balance or the bank statement balance, adjusting for the missing items until the two adjusted figures agree. An updated cash book is often prepared first to record items discovered from the bank statement.
调节过程从现金簿余额或银行对账单余额出发，对遗漏项目进行调整，直到两个调整后的数字相符。通常先更新现金簿，记录从银行对账单中发现的各项。
Key adjustments to the cash book: add bank interest received, deduct bank charges and standing orders. For the bank statement side: deduct unpresented cheques and add outstanding deposits.
现金簿的关键调整：加上收到的银行利息，减去银行手续费和自动转账付款。银行对账单方的调整：减去未兑现支票，加上在途存款。
11. Control Accounts | 控制账户
Control accounts are summary accounts maintained in the general ledger to verify the total of the individual balances in the sales ledger (trade receivables control account) and purchases ledger (trade payables control account).
控制账户是总分类账中设立的汇总账户，用于核对销售分类账（应收账款控制账户）和采购分类账（应付账款控制账户）中各明细余额的合计。
The trade receivables control account is debited with credit sales and sundry debits (e.g., dishonoured cheques), and credited with cash received, discounts allowed and returns inwards. The closing balance should equal the sum of all individual trade receivable balances.
应收账款控制账户的借方记录赊销收入和其他借记项目（如拒付支票），贷方记录收到的现金、给予的折扣和销售退回。期末余额应等于所有应收账款明细余额之和。
Control accounts help locate errors and provide a quick check on the accuracy of the sales and purchases ledgers. They are also useful for internal control and fraud prevention.
控制账户有助于发现错误，并能快速检查销售和采购分类账的准确性。它们也有助于内部控制和防止舞弊。
12. Ratio Analysis | 比率分析
Ratio analysis evaluates the profitability, liquidity and efficiency of a business using figures from the financial statements. Key profitability ratios include:
比率分析利用财务报表中的数据评估企业的盈利能力、流动性和效率。关键的盈利能力比率包括：
- Gross Profit Margin = (Gross Profit ÷ Revenue) × 100%
- Profit Margin = (Profit for the Year ÷ Revenue) × 100%
- Return on Capital Employed (ROCE) = (Profit for the Year ÷ Capital Employed) × 100%
- 毛利率 = (毛利 ÷ 收入) × 100%
- 净利润率 = (本年利润 ÷ 收入) × 100%
- 资本报酬率 (ROCE) = (本年利润 ÷ 已用资本) × 100%
Liquidity ratios assess short-term solvency. The current ratio (Current Assets ÷ Current Liabilities) and quick ratio (liquid assets ÷ Current Liabilities) are commonly examined. A current ratio around 2:1 is often considered acceptable, though it varies by industry.
流动性比率评估短期偿债能力。流动比率（流动资产 ÷ 流动负债）和速动比率（速动资产 ÷ 流动负债）是常见考点。流动比率约在 2:1 一般被认为可接受，但会因行业而异。
Analysis of these ratios over time and against industry benchmarks reveals trends and areas for improvement. Students should be able to interpret ratio results and suggest ways to enhance profitability or liquidity.
分析这些比率的时序变化并进行行业对标，能够揭示趋势与改进空间。学生应能解读比率结果，并提出提升盈利能力或流动性的建议。
