1. The Accounting Equation and Basic Concepts | 会计等式与基本概念
The accounting equation is the bedrock of all financial record-keeping: Assets = Liabilities + Capital. Every single transaction a business undertakes will affect at least two elements of this equation, yet the equation itself must always remain in balance. This dual effect is the foundation of double-entry bookkeeping.
会计等式是一切财务记录的根本：资产 = 负债 + 资本。企业发生的每一笔交易都会影响该等式中至少两个要素，但等式本身必须始终平衡。这种双重影响正是复式记账法的基础。
Assets are resources controlled by the business (such as cash, inventory, and equipment) from which future economic benefits are expected to flow. Liabilities represent present obligations that will lead to an outflow of resources, including trade payables and bank loans. Capital is the owner’s residual interest in the business after deducting all liabilities.
资产是企业控制的资源（如现金、存货和设备），预计能够带来未来经济利益。负债代表了将导致资源流出的现时义务，包括应付账款和银行借款。资本是扣除所有负债后所有者对企业剩余的权益。
Several fundamental accounting concepts underpin the preparation of financial statements: business entity states that the owner’s personal affairs are separate from the business; going concern assumes the business will continue to operate for the foreseeable future; accruals (matching) requires income and expenses to be recorded in the period they relate to, not when cash is received or paid; prudence means assets and profits should not be overstated, while liabilities and expenses should be fully provided for; and consistency demands that the same accounting treatments are applied from one period to the next.
支撑财务报表编制的若干基本会计概念包括：会计主体概念指出所有者的私人事务与企业分离；持续经营概念假设企业在可预见的将来会继续运营；权责发生制（配比）概念要求收入和费用在其相关期间记录，而非收付现金时；谨慎性概念意味着资产和利润不应被高估，而负债和费用需充分计提；一致性概念要求在前后不同期间采用相同的会计处理方法。
2. Double-Entry Bookkeeping | 复式记账法
Every financial transaction is recorded using the principle of double entry. 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, keeping the accounting equation in equilibrium.
每一笔财务交易都按照复式记账原则进行记录。每笔交易都在一个账户中记借方，在另一个账户中记贷方，借方总额必须始终等于贷方总额，使会计等式保持平衡。
The rules for double entry are systematic: increases in assets and expenses are recorded on the debit side; increases in liabilities, capital, and income are recorded on the credit side. Conversely, decreases in assets and expenses require a credit entry, while decreases in liabilities, capital, and income require a debit entry.
复式记账的规则是有系统的：资产和费用的增加记在借方；负债、资本和收入的增加记在贷方。反之，资产和费用的减少需要记贷方，负债、资本和收入的减少需要记借方。
Each account is represented by a ‘T-account’ with a left (debit) side and a right (credit) side. When a transaction occurs, you identify the two accounts affected, decide whether each is being increased or decreased, and then apply the rules to determine the debit and credit entries. For example, a cash purchase of inventory increases the asset of inventory (debit) and decreases the asset of cash (credit).
每个账户用’T 形账户’表示，有左（借方）和右（贷方）两方。当发生交易时，需要确定所影响的两个账户，判断每个账户是增加还是减少，然后应用规则确定借方和贷方分录。例如，用现金购买存货，存货资产增加（借方），现金资产减少（贷方）。
3. Journal Entries and Ledger Accounts | 日记账与分类账
The journal is the book of prime entry where transactions are first recorded in chronological order before being posted to the ledgers. A journal entry states the date, the accounts to be debited and credited, a brief narrative, and the monetary amounts.
日记账是原始记录簿，交易按时间顺序首先记录于此，之后再过入分类账。一个日记账分录会注明日期、应借记和应贷记的账户、简短摘要以及金额。
Specialised journals are used for frequent transactions: the purchases journal records credit purchases, the sales journal records credit sales, the returns inwards journal records goods returned by customers, the returns outwards journal records goods returned to suppliers, and the cash book records all cash and bank transactions.
专用日记账用于频繁发生的交易：采购日记账记录赊购，销售日记账记录赊销，销售退回日记账记录客户退回商品，采购退回日记账记录退给供应商的商品，现金日记账记录所有现金和银行存款交易。
After recording in the journals, entries are posted to the nominal (general) ledger, the sales ledger (debtors’ accounts), and the purchases ledger (creditors’ accounts). Each individual customer or supplier has a separate account in the sales or purchases ledger. The total of all personal ledger balances should agree with the control accounts in the nominal ledger.
在日记账中记录后，分录被过入总分类账、销售分类账（客户账户）和采购分类账（供应商账户）。每个单独的客户或供应商在销售或采购分类账中都有一个单独账户。所有个人分类账余额的合计应与总分类账的控制账户相符。
4. Trial Balance | 试算平衡表
A trial balance is a list of all the balances from the nominal ledger accounts at a particular date, with debit balances in one column and credit balances in another. Its main purpose is to check the arithmetic accuracy of the double-entry records. If total debits equal total credits, the books are said to ‘balance’.
试算平衡表是在某一特定日期，将总分类账所有账户余额列示的表，借方余额列在一栏，贷方余额列在另一栏。其主要目的是检验复式记录在算术上的准确性。如果借方总额等于贷方总额，就说账目’平衡’了。
A trial balance can detect certain types of errors, such as a single entry (debit without credit), an unequal debit and credit entry, or an addition error in an account. However, it cannot reveal errors of omission (a transaction completely missed), errors of commission (correct amount but wrong account of the same class), errors of principle (amount posted to wrong class of account, e.g. capital expenditure treated as revenue), compensating errors, or a complete reversal of debits and credits.
试算平衡表能发现某些类型的错误，例如单边分录（有借方无贷方）、借贷方金额不等、或账户加总错误。但是它不能揭示遗漏错误（完全漏记交易）、记录错误（金额正确但记入同类型的错误账户）、原则错误（记入错误类别的账户，例如资本性支出当做收益性支出处理）、抵消性错误以及完全颠倒借贷的错误。
5. Depreciation of Non-Current Assets | 固定资产折旧
Depreciation is the systematic allocation of the cost of a non-current asset over its useful economic life. It matches the expense of using the asset to the periods that benefit from it, in compliance with the accruals (matching) concept. The two main methods specified by AQA are the straight-line method and the reducing balance method.
折旧是将固定资产的成本在其使用经济年限内进行系统分配。它根据权责发生制（配比）概念，将使用资产的费用与受益期间配比起来。AQA 规定的两种主要方法是直线法和余额递减法。
Straight-line method: depreciation charge is the same each year. The formula is:
Annual Depreciation = (Cost – Residual Value) ÷ Useful Economic Life
直线法：每年折旧费用相同。公式为：
年折旧额 = (原值 – 残值) ÷ 使用经济年限
Reducing balance method: a fixed percentage is applied to the net book value (cost less accumulated depreciation) each year. This results in higher depreciation charges in earlier years and lower charges in later years.
余额递减法：每年对一个固定百分比，乘以账面净值（原值减累计折旧）。结果是最初几年的折旧额较高，以后年份较低。
The double entry for recording depreciation is: debit the income statement (depreciation expense) and credit the provision for depreciation (accumulated depreciation) account. The non-current asset appears in the statement of financial position at its net book value (cost less accumulated depreciation).
记录折旧的复式分录为：借方记录利润表（折旧费用），贷方记录折旧准备（累计折旧）账户。固定资产在财务状况表中以其账面净值（原值减累计折旧）列示。
6. Irrecoverable Debts and Provision for Doubtful Debts | 坏账与可疑债务准备
An irrecoverable debt arises when a credit customer is unable to pay the amount owed, and it becomes clear that the business will not recover the money. Accounting treatment: the debt is written off by debiting the irrecoverable debts expense account and crediting the trade receivables account. If a debt previously written off is later recovered, the recovery is recorded by debiting cash/bank and crediting irrecoverable debts recovered (income).
坏账是指当赊销客户无力支付欠款，且明确企业无法收回该款项时产生的债务。会计处理：将坏账核销，借方记坏账费用，贷方记应收账款。如果之前已核销的坏账被收回，收回时借方记现金/银行存款，贷方记坏账收回（收益）。
A provision for doubtful debts is an estimate of the amount of trade receivables that might not be collected, based on past experience and known risks. This adjustment follows the prudence concept. The provision is calculated, often as a percentage of trade receivables, and adjustments are made for any increase or decrease from the prior period’s provision.
可疑债务准备是根据过去经验和已知风险，对应收账款中可能无法收回的金额作出的估计。这一调整遵循谨慎性概念。计算时通常按应收账款的一个百分比，然后根据与前期准备的差异进行调整增减。
The double entry for creating or increasing a provision: debit the income statement (increase in provision for doubtful debts) and credit the provision for doubtful debts account. A decrease in provision is credited to the income statement. The net trade receivables figure shown in the statement of financial position is total trade receivables less the provision for doubtful debts.
计提或增加准备的复式分录：借方记利润表（可疑债务准备增加），贷方记可疑债务准备账户。准备的减少则贷记利润表。财务状况表中列示的应收账款净额是应收账款总额减去可疑债务准备。
7. Accruals and Prepayments | 应计与预付款项
Under the accruals concept, expenses and income must be matched to the period to which they relate. At the end of an accounting period, adjustments are often needed for accrued expenses (expenses incurred but not yet paid for) and prepaid expenses (expenses paid in advance for future periods).
按照权责发生制概念，费用和收入必须与它们归属的期间相配比。在会计期末，经常需要对应计费用（已发生但尚未支付的费用）和预付费用（为未来期间预先支付的费用）进行调整。
An accrued expense means the business has used a service or received goods, but the invoice has not yet been settled. Adjustment: debit the relevant expense account (increase) and credit accruals (a current liability). For example, an electricity bill for the last month owed but not yet recorded is an accrual.
应计费用意味着企业已使用了服务或收到了货物，但尚未支付相关账单。调整分录：借记相关费用账户（增加），贷记应计项目（一项流动负债）。例如，上个月的应付电费但未入账就是一项应计费用。
A prepayment occurs when a payment is made in advance, such as insurance for the next year. Adjustment: reduce the expense for the period by crediting the expense account and create a current asset by debiting prepayments. The income statement only includes the amount that relates to the period.
当款项提前支付时，如为下一年度支付的保险，就发生了预付款项。调整：通过贷记费用账户减少当期的费用，并借记预付款项形成一项流动资产。利润表只包含归属于本期的那部分金额。
Similarly, accrued income (earned but not yet received) and deferred income (received in advance for services not yet provided) are adjusted. These ensure that the financial statements present a true and fair view of performance and position.
类似地，应计收入（已赚取但尚未收到）和递延收入（预先收到但服务尚未提供）也需要调整。这些调整确保财务报表真实公允地反映业绩和状况。
8. Control Accounts | 控制账户
Control accounts are summary accounts kept in the nominal ledger that represent the total of all individual balances in the sales ledger (sales ledger control account) and the purchases ledger (purchases ledger control account). They act as an internal check to detect errors and help in locating discrepancies.
控制账户是设在总分类账中的汇总账户，代表销售分类账（销售分类账控制账户）和采购分类账（采购分类账控制账户）中所有个别余额的合计。它们作为内部核查手段，用来发现错误并帮助定位差异。
The sales ledger control account is debited with total credit sales from the sales journal and any interest charged to debtors, and credited with receipts from debtors, returns inwards, and irrecoverable debts written off. The closing balance should equal the total of the individual debtor accounts in the sales ledger.
销售分类账控制账户借方记录来自销售日记账的赊销总额以及向客户收取的利息，贷方记录客户付款、销售退回和核销的坏账。其期末余额应等于销售分类账中各客户账户的合计余额。
The purchases ledger control account is credited with total credit purchases and returns outwards debits, and debited with payments made to suppliers and discounts received. Its closing credit balance must agree with the list of individual creditor balances.
采购分类账控制账户贷方记录赊购总额和借记的采购退回，借方记录对供应商的付款和取得的折扣。其期末贷方余额必须与供应商个别余额清单一致。
9. Bank Reconciliation | 银行对账
A bank reconciliation statement compares the cash book balance (the business’s record) with the bank statement balance (the bank’s record) at a particular date, and explains any differences. The main reasons for differences are timing differences: unpresented cheques (issued but not yet cleared) and lodgements not yet credited, plus any errors or omissions in the cash book.
银行对账调节表将现金簿余额（企业记录）与银行对账单余额（银行记录）在特定日期进行比较，并解释任何差异。产生差异的主要原因在于时间差：未兑现支票（已签发但尚未兑付）和未记账的银行存款，以及现金簿中的错误或遗漏。
The process starts by updating the cash book for items discovered from the bank statement, such as bank charges, direct debits, standing orders, and BACS receipts. The adjusted cash book balance is then used in the bank reconciliation statement.
调节过程首先根据银行对账单上发现的项目更新现金簿，例如银行手续费、直接借记、定期付款指令和 BACS 收款。然后使用调整后的现金簿余额进行银行对账调节。
The typical format works from the bank statement balance: add lodgements not yet credited, subtract unpresented cheques, and adjust for any bank errors to arrive at the adjusted cash book balance. A correct reconciliation confirms that both records are consistent.
典型的格式从银行对账单余额出发：加上未记入贷方的款项，减去未兑现支票，并对任何银行错误进行调整，得出调整后现金簿余额。正确的调节能确认双方记录一致。
10. Financial Statements for Sole Traders | 独资企业财务报表
Year 11 AQA Accounting requires the preparation of the income statement (trading and profit and loss account) and the statement of financial position for a sole trader. The income statement calculates gross profit (sales less cost of sales) and then deducts expenses to determine profit for the year.
Year 11 AQA 会计要求能够编制独资企业的利润表（购销损益表）和财务状况表。利润表先计算毛利（销售收入减销售成本），再扣除各项费用来确定当年的利润。
Cost of sales is calculated as opening inventory plus purchases less closing inventory. Purchases are adjusted for returns outwards, and carriage inwards is added to purchases. In the profit and loss section, expenses such as rent, wages, light and heat, and depreciation are listed. Adjustments for accruals, prepayments, and provision for doubtful debts ensure the matching concept is followed.
销售成本按期初存货加采购减期末存货计算。采购需要调整采购退回，采购运费加到采购额中。在损益部分，列出租金、工资、照明取暖费和折旧等费用。对应计、预付款项和可疑债务准备进行调整，确保遵循配比概念。
The statement of financial position shows assets, liabilities, and capital at the end of the period. Non-current assets are recorded at net book value. Current assets include inventory, trade receivables, prepayments, and cash at bank. Current liabilities are amounts falling due within one year. The capital section starts with opening capital, adds profit for the year, and deducts drawings to find closing capital. The total of net assets (assets minus liabilities) must equal closing capital.
财务状况表反映期末的资产、负债和资本。固定资产按账面净值记录。流动资产包括存货、应收账款、预付款项和银行存款。流动负债是一年内到期的欠款。资本部分从期初资本开始，加上本年利润，减去提款，得出期末资本。净资产合计（资产减负债）必须等于期末资本。
11. Accounting Concepts and Conventions | 会计概念与惯例
AQA GCSE Accounting places strong emphasis on the underlying concepts that govern the preparation of accounts. Beyond those already introduced, the money measurement concept states that only transactions capable of being expressed in monetary terms are recorded. The historical cost convention dictates that assets are normally shown at their original cost less depreciation, rather than at current valuation.
AQA GCSE 会计特别强调指导账务编制的基本概念。除前面已介绍的外，货币计量概念指出，只有能以货币表示的才予以记录。历史成本惯例规定，资产通常按其原始成本减折旧列示，而非按当前估值。
The materiality concept allows strict application of accounting standards to be ignored if the amounts involved are insignificant and would not affect users’ decisions. The realisation concept recognises revenue when it is earned and the legal right to receive payment is established, not necessarily when cash is received. The dual aspect concept is the foundation of double entry: every transaction has two equal and opposite effects.
重要性概念允许在金额微小且不影响使用者决策的情况下忽略严格应用会计准则。实现概念在收入已赚取且收款的法律权利确立时确认收入，而不一定在收到现金时。双重影响概念是复式记账的基础：每笔交易都有两个相等且相反的影响。
These concepts ensure financial statements are reliable, comparable, and understandable. Students must be able to identify the concept applied in given scenarios and explain how departure from a concept could mislead users of accounts.
这些概念确保了财务报表的可靠性、可比性和可理解性。学生需要能够识别在给定情形下应用了哪个概念，并解释若背离某个概念会怎样误导报表使用者。
12. Introduction to Ratio Analysis | 比率分析入门
Ratio analysis helps users of accounts interpret financial statements and assess a business’s profitability, liquidity, and efficiency. At Year 11, AQA introduces several key ratios that can be calculated from the income statement and statement of financial position.
比率分析有助于报表使用者解读财务报表，评估企业的盈利能力、流动性和效率。在 Year 11 阶段，AQA 介绍了几项可以从利润表和财务状况表计算的关键比率。
Gross profit margin = (Gross Profit ÷ Sales Revenue) × 100%. It indicates the percentage of sales revenue left after covering the cost of goods sold. A decline may suggest rising purchase costs or reduced selling prices.
毛利率 = (毛利 ÷ 销售收入) × 100%。它表明在弥补了销售成本后剩下多少比例的销售收入。下降可能意味着采购成本上升或销售价格降低。
Profit for the year margin (net profit margin) = (Profit for the Year ÷ Sales Revenue) × 100%. This shows the overall profitability after all expenses. It is useful for comparing performance across periods.
净利润率 = (本年利润 ÷ 销售收入) × 100%。它展示了扣除所有费用后的综合盈利能力，对跨期比较很有用。
Liquidity ratios include the current ratio = Current Assets ÷ Current Liabilities, and the liquid (acid test) ratio = (Current Assets – Inventory) ÷ Current Liabilities. These measure the business’s ability to pay short-term debts as they fall due.
流动性比率包括流动比率 = 流动资产 ÷ 流动负债，以及速动比率（酸性测试比率） = (流动资产 – 存货) ÷ 流动负债。它们衡量企业偿还到期短期债务的能力。
Efficiency ratios such as trade receivables collection period = (Trade Receivables ÷ Credit Sales) × 365 days, and trade payables payment period = (Trade Payables ÷ Credit Purchases) × 365 days, show how quickly the business collects money from customers and pays its suppliers.
效率比率比如应收账款收款天数 = (应收账款 ÷ 赊销总额) × 365 天，以及应付账款付款天数 = (应付账款 ÷ 赊购总额) × 365 天，反映了企业从客户那里收款和支付供应商货款的速度。
