📚 Core Knowledge of Year 10 AQA Accounting | Year 10 AQA 会计：核心知识点梳理
Year 10 is the foundation stage for AQA GCSE Accounting, where learners start to understand how businesses record, report and analyse financial information. This article condenses the essential topics you will encounter – from the accounting equation to basic financial statements and key adjustments – into a clear revision guide. Each concept is explained in plain English and matched with Chinese to support bilingual learning.
Year 10 是 AQA 会计课程的起始阶段，学生将首次接触企业如何记录、报告和分析财务信息。本文梳理了这个阶段的核心知识点，从会计恒等式到基本财务报表和关键调整项，用简洁的说明搭配中文解释，帮助你系统复习。
1. The Purpose of Accounting | 会计的目的
Accounting is the process of identifying, recording, classifying and summarising financial transactions so that useful information can be provided to decision-makers. Its main purposes are stewardship (showing how resources have been used), decision-making (helping managers plan and control) and accountability (reporting to owners).
会计是识别、记录、分类和汇总财务交易的过程，为决策者提供有用的信息。它的主要目的是资源受托责任（展示资源如何使用）、辅助决策（帮助管理者规划和控制）和问责（向所有者报告）。
For businesses, accounting helps answer three key questions: is the business making a profit, what does it own and owe, and where is the cash going? Without an organised accounting system, even a profitable business can fail through poor cash management.
对企业来说，会计帮助回答三个关键问题：企业是否盈利、它拥有什么和欠什么、现金流向何处。没有规范的会计系统，即使盈利的企业也可能因现金管理不善而倒闭。
2. The Accounting Equation | 会计恒等式
The accounting equation is the backbone of the double-entry system. It states that everything a business owns (assets) is funded either by what it owes (liabilities) or by the owner's investment (equity/capital). The fundamental relationship is:
会计恒等式是复式记账法的基石。它表明企业拥有的一切（资产）都是由所欠的（负债）或所有者投入的（权益/资本）来提供资金的。基本关系为：
Assets = Liabilities + Equity
Equity is sometimes replaced with 'Capital' in sole trader accounts. This equation must always balance after every transaction. For instance, buying equipment with cash changes the composition of assets but leaves both sides equal; taking out a loan increases both assets (cash) and liabilities (loan payable).
在个体经营者账目中，权益有时用'资本'代替。每笔交易发生后，等式必须始终保持平衡。例如，用现金购买设备改变了资产的构成，但两边仍然相等；借入贷款则同时增加资产（现金）和负债（应付贷款）。
3. Source Documents and Books of Prime Entry | 原始凭证和日记簿
Transactions start with source documents such as invoices, credit notes, cheque counterfoils and receipts. These are the original records that prove a transaction has occurred. They are then summarised in books of prime entry before being posted to ledgers.
交易始于原始凭证，如发票、红字发票（贷项通知单）、支票存根和收据。这些是证明交易发生的原始记录。它们先汇总在日记簿（原始分录簿）中，再过账至分类账。
The main books of prime entry are: sales day book (for credit sales), purchases day book (for credit purchases), returns inwards/outwards books, cash book (for all bank and cash transactions) and the general journal for non-routine entries.
主要的日记簿包括：销售日记账（记录赊销）、采购日记账（记录赊购）、进货退出/销货退回日记账、现金日记账（记录所有银行和现金交易）以及普通日记账（记录非常规分录）。
4. Double-Entry Bookkeeping | 复式记账法
Double-entry is the rule that every financial transaction affects at least two accounts – one debit and one credit – and the total debits must always equal total credits. This ensures the accounting equation stays in balance.
复式记账法规则是：每笔财务交易至少影响两个账户——一个借方和一个贷方——且借方总额必须始终等于贷方总额。这保证了会计恒等式永远平衡。
The mnemonic 'DEAD CLIC' helps remember which side increases: Debit increases Expenses, Assets, Drawings; Credit increases Liabilities, Income, Capital. For example, when a business purchases inventory for cash, debit Purchases (expense) and credit Cash (asset).
用记忆口诀'DEAD CLIC'可以记住增减方：借方增加费用、资产、提款；贷方增加负债、收入、资本。例如，企业用现金购买存货时，借记采购（费用），贷记现金（资产）。
5. Ledger Accounts and Balances | 分类账和余额
After transactions are recorded in the books of prime entry, they are posted to T-accounts in the general ledger. Each account has a debit (left) and credit (right) side. At the end of a period, accounts are balanced: the difference between the two sides is carried down as the balance to be reported in the trial balance.
交易在日记簿中记录后，被过账到总分类账中的T型账户。每个账户都有借方（左）和贷方（右）。期末，账户需要结平：两方差额作为余额结转至下期，并出现在试算表中。
Asset and expense accounts normally have debit balances, while liability, capital and income accounts normally have credit balances. An account with a debit balance is said to be 'in debit'; an account with a credit balance is 'in credit'.
资产和费用账户通常有借方余额，而负债、资本和收入账户通常有贷方余额。有借方余额的账户称为'借余'，有贷方余额的账户称为'贷余'。
6. Trial Balance | 试算表
A trial balance is a list of all ledger account balances, split into debit and credit columns. Its main purpose is to check the arithmetical accuracy of the double-entry records – total debits should equal total credits. It is prepared at the end of a financial period before drafting financial statements.
试算表是列出所有分类账余额的清单，分为借方栏和贷方栏。其主要目的是检验复式记账记录的算术准确性——借方合计应等于贷方合计。它在会计期末、编制财务报表之前编制。
If a trial balance does not balance, common errors include single-sided entries, carrying down balances incorrectly, or transposition errors. However, some errors – such as omission or compensating errors – do not prevent the trial balance from appearing balanced.
如果试算表不平，常见错误包括只记单边分录、余额结转错误或数字颠倒。但是，有些错误——如遗漏错误或抵销错误——并不会使试算表显示出不平。
7. Income Statement (Trading and Profit & Loss Account) | 损益表 (购销及损益账户)
The income statement calculates the profit or loss for a period. For a trading business, it usually has two sections: the trading account (showing gross profit) and the profit and loss account (showing net profit).
损益表计算一个期间的利润或亏损。对于贸易企业，它通常分为两部分：购销账户（显示毛利）和损益账户（显示净利润）。
Gross profit = Sales revenue – Cost of goods sold. Cost of goods sold = Opening inventory + Purchases – Purchases returns – Closing inventory. Net profit = Gross profit + Other income – Expenses.
毛利 = 销售收入 – 销售成本。销售成本 = 期初存货 + 采购 – 购货退回 – 期末存货。净利润 = 毛利 + 其他收入 – 费用。
Key expenses include rent, wages, advertising, insurance and depreciation. The income statement covers a period of time, typically one year, and follows the accruals concept: revenues and expenses are matched to the period in which they are earned or incurred, not when cash is received or paid.
主要费用包括租金、工资、广告费、保险费和折旧。损益表覆盖一段时间（通常一年），并遵循权责发生制概念：收入和费用与它们所赚取或发生的期间相匹配，而不是现金收付时点。
8. Statement of Financial Position (Balance Sheet) | 财务状况表 (资产负债表)
The statement of financial position shows the assets, liabilities and equity of a business at a specific point in time. It is prepared after the income statement because the net profit (or loss) is added to or deducted from the owner's capital.
财务状况表列示企业在某一特定时点的资产、负债和权益。它在损益表之后编制，因为净利润（或净亏损）会被加入或扣除所有者资本。
Non-current assets (e.g. machinery, vehicles) are listed first, followed by current assets (inventory, trade receivables, cash). Current liabilities (trade payables, bank overdraft) are subtracted from current assets to show net current assets. Then non-current liabilities are deducted, and the residual is the owner's equity (capital + net profit – drawings). The total must always equal the total of equity and liabilities.
非流动资产（如机器、车辆）先列示，然后是流动资产（存货、应收账款、现金）。流动负债（应付账款、银行透支）从流动资产中扣除，得出流动净资产。再扣除非流动负债，剩余部分为所有者权益（资本 + 净利润 – 提款）。资产总额必须始终等于权益加负债总额。
9. Adjustments: Depreciation | 调整：折旧
Depreciation is the systematic allocation of a non-current asset's cost over its useful life. It recognises that assets lose value as they are used, and matches the expense with the revenue the asset helps generate. Straight-line and reducing-balance methods are commonly introduced at Year 10.
折旧是将非流动资产的成本在其使用寿命内系统分配的过程。它确认资产在使用中逐渐贬值，并将费用与资产帮助产生的收入匹配。在 Year 10 阶段通常介绍直线法和余额递减法。
Straight-line depreciation: (Cost – Residual value) ÷ Useful life. The same amount is charged each year. The double entry is: debit Depreciation Expense (income statement), credit Accumulated Depreciation (statement of financial position, deducted from the asset's cost).
直线法折旧：(成本 – 残值) ÷ 使用年限。每年计提相同金额。会计分录为：借记折旧费用（损益表），贷记累计折旧（财务状况表，从资产成本中扣除）。
Depreciation reduces the carrying amount of the asset on the statement of financial position and reduces reported profit, providing a more realistic view of performance.
折旧减少了财务状况表中资产的账面净值，也降低了报告利润，使业绩更真实。
10. Adjustments: Accruals and Prepayments | 调整：应计和预付款
The accruals concept requires expenses to be recorded in the period they are incurred, not when paid. An accrual is an expense that has been used but not yet billed or paid (e.g. electricity consumed but invoice not received). A prepayment is an expense paid in advance for a future period (e.g. insurance paid for next year).
权责发生制概念要求费用在实际发生的期间记录，而不是支付时。应计费用是已发生但尚未开票或支付的费用（如已耗用的电费但未收到账单）。预付款是提前支付下一期间的费用（如预付下年保险费）。
To adjust for an accrual, we add the missing expense to the relevant expense account (debit expense, credit accruals liability). For a prepayment, we deduct the future amount from the expense (debit prepayment asset, credit expense). These adjustments ensure the income statement shows the true cost for the year and the statement of financial position reports correct liabilities and assets.
调整应计时，将缺失的费用加到相关费用账户（借记费用，贷记应计负债）。调整预付款时，从费用中扣除未来金额（借记预付资产，贷记费用）。这些调整确保损益表反映当年真实费用，财务状况表报告正确的负债和资产。
11. Bad Debts and Provision for Doubtful Debts | 坏账和坏账准备
Not all trade receivables will pay the amount owed. A bad debt occurs when a customer fails to pay after all reasonable attempts to collect; it becomes an irrecoverable amount. The double entry is: debit Bad Debts (expense), credit Trade Receivables (asset).
并非所有应收账款都能收回。当经过所有合理催收后客户仍不付款，该款项就成为坏账（无法收回的金额）。分录为：借记坏账（费用），贷记应收账款（资产）。
Additionally, prudence requires a provision (allowance) for doubtful debts to be made before it is certain which customers will default. This estimates likely future bad debts based on past experience. The adjustment increases the provision (debit expense, credit Provision for Doubtful Debts) and reduces trade receivables on the statement of financial position.
此外，谨慎性原则要求在有明确客户违约前，先计提坏账准备（呆账准备）。它根据历史经验估计未来可能发生的坏账。调整分录为借记费用，贷记坏账准备，并减少财务状况表上的应收账款净额。
12. Bank Reconciliation | 银行存款调节表
A bank reconciliation statement explains the difference between the cash book balance and the bank statement balance at a particular date. Differences arise from timing (unpresented cheques, outstanding deposits) and errors or omissions (bank charges, direct debits not yet recorded in the cash book).
银行存款调节表解释在特定日期现金日记账余额与银行对账单余额之间的差异。差异来自时间差（未兑现支票、未达存款）和错误或遗漏（银行手续费、尚未记入现金日记账的直接借记）。
To prepare a bank reconciliation, update the cash book for any items discovered from the bank statement (e.g. bank charges, interest, direct debits). Then prepare the reconciliation statement starting from the updated cash book balance, adding unpresented cheques and subtracting outstanding deposits (or vice versa, depending on the method) to arrive at the bank statement balance.
编制银行存款调节表时，先根据银行对账单找出未记录项目（如银行手续费、利息、直接借记）更新现金日记账。然后编制调节表，从更新后的现金日记账余额出发，加上未兑现支票，减去未达存款（或反之，依方法而定），得出银行对账单余额。
Bank reconciliation is a key control tool that helps detect errors and prevent fraud, making it an essential skill in Year 10 accounting.
银行存款调节表是重要的控制工具，有助于发现错误和防止舞弊，是 Year 10 会计的关键技能。
