1. AQA Accounting Syllabus at a Glance | 课程大纲一览
The AQA A-level Accounting course (first year) covers two main areas: financial accounting and management accounting. In Year 12, you will focus on the recording and presentation of financial information for sole traders. This includes double-entry bookkeeping, preparation of final accounts, and adjustments for items such as depreciation and accruals. You will also learn about accounting concepts and the regulatory framework that underpins all reporting.
AQA A-level 会计课程（第一年）涵盖两大领域：财务会计和管理会计。在 Year 12，您将重点学习独资经营者的财务信息记录与列报。这包括复式记账、期末账目编制以及折旧和应计项目等调整。您还将学习支撑所有报告的会计概念和监管框架。
The course builds on the basics and develops your ability to interpret and analyse financial statements, setting the stage for more complex topics in Year 13 such as partnerships, limited companies, and advanced management accounting techniques.
该课程以基础为依托，培养您解读和分析财务报表的能力，为 Year 13 更复杂的主题奠定基础，例如合伙企业、有限公司和高级管理会计技术。
2. The Fundamental Accounting Equation | 基础会计等式
y business transaction affects this equation, ensuring that it always balances. Assets are resources controlled by the business (e.g., cash, inventory, equipment). Liabilities represent obligations to external parties (e.g., trade payables, bank loans). Equity is the owner's residual interest in the assets after deducting liabilities.
会计等式是复式记账的基石：资产 = 负债 + 所有者权益。每笔企业交易都会影响这个等式，确保其始终保持平衡。资产是企业控制的资源（如现金、存货、设备）。负债代表对外部方的义务（如应付账款、银行贷款）。所有者权益是扣除负债后所有者在资产中的剩余权益。
| Transaction | Effect on Equation |
| Owner invests £5,000 cash | Assets (Cash +£5,000) and Equity (Capital +£5,000) |
| Buy equipment for £2,000 cash | Assets (Equipment +£2,000; Cash -£2,000) – no change in total |
Assets = Liabilities + Equity
3. Double-Entry Bookkeeping System | 复式记账系统
Every transaction is recorded in at least two accounts – one debit and one credit – so that the accounting equation remains balanced. The double-entry rule is: for every debit, there must be a corresponding credit. Debits increase assets and expenses, while credits increase liabilities, equity and income.
每笔交易至少在两个账户中记录——一个借方和一个贷方——以便会计等式保持平衡。复式记账规则是：每一笔借方，必须对应一笔贷方。借方增加资产和费用，贷方增加负债、所有者权益和收入。
Remember the mnemonic 'DEAD CLIC': Debits increase Expenses, Assets, Drawings; Credits increase Liabilities, Income, Capital. For example, a credit purchase of inventory: debit Purchases (expense), credit Trade Payables (liability). A cash sale: debit Cash (asset), credit Sales (income).
记住助记符 'DEAD CLIC'：Debits 增加 Expenses, Assets, Drawings；Credits 增加 Liabilities, Income, Capital。例如，赊购存货：借记采购（费用），贷记应付账款（负债）。现销：借记现金（资产），贷记销售收入（收入）。
4. Source Documents and Books of Prime Entry | 原始凭证与原始分录簿
Transactions are initially recorded on source documents such as invoices, credit notes, receipts and bank statements. These are then entered into books of prime entry (day books) before being posted to the ledgers. Common books of prime entry include the sales day book, purchases day book, sales returns day book, purchases returns day book, cash book and the general journal.
交易最初记录在原始凭证上，如发票、贷项通知单、收据和银行对账单。然后这些凭证被录入原始分录簿（日记簿），再过账到分类账中。常见的原始分录簿包括销售日记簿、采购日记簿、销售退回日记簿、采购退回日记簿、现金日记簿和通用日记账。
The cash book serves as both a book of prime entry and a ledger account, recording all cash and bank transactions. It replaces separate cash and bank T-accounts in many systems, and its balance is used directly in the trial balance.
现金日记簿既是原始分录簿也是分类账账户，记录所有现金和银行交易。在许多系统中它取代了单独的现金和银行 T 型账户，其余额直接用于试算平衡表。
5. Ledger Accounts and the Trial Balance | 分类账与试算平衡表
After recording in day books, transactions are posted to ledger accounts (T-accounts). Each account has a debit side and a credit side. At the end of a period, the balances of all accounts are listed in a trial balance to check the arithmetic accuracy of the double-entry system. If total debits equal total credits, the trial balance agrees.
在日记簿记录后，交易被过账到分类账账户（T 型账户）。每个账户有借方和贷方。期末，所有账户的余额被列示在试算平衡表中，以检查复式记账系统的算术准确性。如果借方总额等于贷方总额，试算平衡表平衡。
However, an agreed trial balance does not guarantee the absence of errors – for example, errors of omission (a transaction not recorded), errors of commission (recorded in wrong account of same type), or errors of principle (incorrect classification) may still exist. This is why end-of-period adjustments are crucial.
然而，平衡的试算平衡表并不保证没有错误——例如，遗漏错误（交易未记录）、记错账户错误（记入同类型的错误账户）或原则性错误（分类不正确）可能仍然存在。这就是为什么期末调整至关重要。
6. Preparing the Income Statement | 编制利润表
ess Cost of goods sold = Gross profit. Cost of goods sold = Opening inventory + Purchases − Closing inventory. From gross profit we deduct operating expenses to arrive at operating profit. Finally, any other income or finance costs are adjusted to give net profit for the period.
利润表（损益表）计算独资经营者在一定期间内的利润或亏损。基本结构是：销售收入减去销售成本 = 毛利。销售成本 = 期初存货 + 采购 − 期末存货。从毛利中我们减去营业费用得出经营利润。最后，调整其他收入或融资成本，得出该期间的净利润。
Net Profit = Gross Profit − Total Operating Expenses + Other Income
A typical income statement might look like this (simplified):
典型的利润表可能如下所示（简化版）：
| Sales | £100,000 |
| Less Cost of Sales | (£60,000) |
| Gross Profit | £40,000 |
| Less Expenses | (£25,000) |
| Net Profit | £15,000 |
7. Preparing the Statement of Financial Position | 编制财务状况表
nting equation: Total assets = Total equity + Total liabilities. Assets are classified into non-current (e.g., machinery, vehicles) and current (e.g., inventory, trade receivables, cash). Liabilities are split into current (due within 12 months) and non-current. Equity typically comprises capital plus retained profits.
财务状况表（资产负债表）列示企业在特定日期的资产、负债和所有者权益。它遵循会计等式：总资产 = 总权益 + 总负债。资产分为非流动资产（如机器、车辆）和流动资产（如存货、应收账款、现金）。负债分为流动负债（12 个月内到期）和非流动负债。所有者权益通常包括资本加留存利润。
This statement does not show profit directly; it shows the financial position, and the net profit from the income statement feeds into equity via retained earnings. It is often prepared after the income statement.
该报表不直接显示利润；它显示财务状况，利润表中的净利润通过留存收益计入所有者权益。它通常在利润表之后编制。
8. Adjustments for Accruals and Prepayments | 应计与预付款项调整
At the end of an accounting period, we must adjust for expenses incurred but not yet paid (accruals) and payments made in advance (prepayments). Accruals increase expenses and create a liability. Prepayments decrease expenses and create a current asset. These adjustments ensure that the income statement reflects the correct expense for the period.
在会计期末，我们必须对已发生但尚未支付的费用（应计费用）和提前支付的款项（预付款项）进行调整。应计费用增加费用并产生一项负债。预付款项减少费用并产生一项流动资产。这些调整确保利润表反映该期间的正确费用。
For example, if annual rent is £12,000 but only £10,000 has been paid, an accrual of £2,000 is required: debit Rent Expense £2,000, credit Accruals £2,000. If insurance of £1,200 was paid for the next year in advance, we debit Prepayments £1,200, credit Insurance Expense £1,200.
例如，如果年租金为 12,000 英镑，但只支付了 10,000 英镑，则需要应计 2,000 英镑：借记租金费用 2,000 英镑，贷记应计费用 2,000 英镑。如果预先支付了下一年度的保险费 1,200 英镑，则借记预付款项 1,200 英镑，贷记保险费费用 1,200 英镑。
9. Depreciation of Non-Current Assets | 非流动资产折旧
Depreciation allocates the cost of a non-current asset over its useful life, matching the expense to the periods that benefit from the asset's use. Two common methods are the straight-line method (equal annual charge) and the reducing balance method (constant percentage on net book value).
折旧将非流动资产的成本在其使用寿命内分摊，将费用与资产使用产生效益的期间进行配比。两种常见方法是直线法（每年等额计提）和余额递减法（按账面净值固定百分比计提）。
Straight-line annual charge = (Cost − Residual value) ÷ Useful life
ue = Cost − Accumulated depreciation. This appears in the statement of financial position.
分录为借记折旧费用，贷记累计折旧（资产备抵账户）。账面净值 = 原值 −
