1. What is Accounting? | 什么是会计？
Accounting is the systematic process of identifying, recording, measuring, classifying, and communicating financial information. Its main purpose is to help stakeholders make informed economic decisions. Accounting is often called the "language of business" because it tells the financial story of a business.
会计是识别、记录、计量、分类和传递财务信息的系统化过程。其主要目的是帮助利益相关者做出明智的经济决策。会计常被称为“商业的语言”，因为它讲述了一个企业的财务故事。
The two main branches of accounting at this level are financial accounting (preparing financial statements for external users) and management accounting (providing information for internal decision-making). In Year 9 Edexcel, the focus is firmly on financial accounting basics.
在这个阶段，会计的两大分支是财务会计（为外部使用者编制财务报表）和管理会计（为内部决策提供信息）。Year 9 Edexcel 的课程重点明确放在财务会计基础上。
2. The Accounting Equation | 会计等式
The accounting equation is the foundation of all bookkeeping. It states that the resources owned by a business (assets) are always equal to the claims against those resources (liabilities plus capital).
会计等式是所有簿记的基础。它表明企业所拥有的资源（资产）总是等于对这些资源的求偿权（负债加资本）。
Assets = Liabilities + Capital
资产 = 负债 + 资本
Assets are items of value that a business owns or controls, such as cash, inventory, and equipment. Liabilities are obligations the business owes to outsiders, like bank loans and trade payables. Capital (or equity) represents the owner's investment in the business plus any retained profit.
资产是企业拥有或控制的有价项目，例如现金、存货和设备。负债是企业欠外部的义务，如银行贷款和应付账款。资本（或所有者权益）代表所有者对企业的投资加上任何留存利润。
Every transaction changes two or more items in the equation, but the equation must always balance. This concept leads directly to double-entry bookkeeping.
每一笔交易都会改变等式中的两个或更多项目，但等式必须始终保持平衡。这一概念直接引出了复式记账法。
3. Double-Entry System | 复式记账体系
The double-entry system records the dual effect of every business transaction. For each transaction, a debit entry must have a corresponding credit entry of equal value. The total of all debits must always equal the total of all credits.
复式记账体系记录每一笔商业交易的双重影响。对于每笔交易，借方分录必须有一笔等值的贷方分录。所有借方总额必须始终等于所有贷方总额。
Double-entry ensures accuracy and provides a complete picture of how a transaction affects the financial position. It is the basis for preparing reliable financial statements.
复式记账保证了准确性，并完整呈现交易如何影响财务状况。它是编制可靠财务报表的基础。
In the classroom, students learn to identify the two accounts involved, determine which account is debited and which is credited, and ensure the accounting equation stays in balance after the entry.
在课堂上，学生学习识别涉及的两个账户，确定哪个账户记借方、哪个账户记贷方，并确保分录后会计等式保持平衡。
4. Debits and Credits Made Simple | 借方与贷方简易指南
Debit (Dr) and credit (Cr) are simply the left and right sides of an account. In asset accounts, an increase is recorded on the debit side and a decrease on the credit side. For liability and capital accounts, the rule is reversed: increases are credits and decreases are debits.
借方 (Dr) 和贷方 (Cr) 仅仅是账户的左方和右方。在资产账户中，增加记在借方，减少记在贷方。对于负债和资本账户，规则相反：增加记贷方，减少记借方。
Income increases capital, so it behaves like capital and increases on the credit side. Expenses decrease capital, so they behave like assets and increase on the debit side. The table below summarises the key rules.
收入会增加资本，所以它的性质类似资本，增加记贷方。费用会减少资本，所以性质类似资产，增加记借方。下表总结了主要规则。
| Account Type | To Increase | To Decrease | Normal Balance |
|---|---|---|---|
| Asset | Debit | Credit | Debit |
| Liability | Credit | Debit | Credit |
| Capital | Credit | Debit | Credit |
| Income | Credit | Debit | Credit |
| Expense | Debit | Credit | Debit |
中文对照：资产增加记借，减少记贷；负债和资本增加记贷，减少记借；收入增加记贷；费用增加记借。记住正常余额方向有助于试算平衡表编制。
5. Ledger Accounts (T-Accounts) | 分类账（T型账户）
A ledger account is a record of all transactions affecting a particular item. In Year 9, we use T-accounts to represent these ledgers because they resemble the letter T, with a left (debit) side and a right (credit) side.
分类账账户是记录所有影响特定项目的交易的工具。在 Year 9 中，我们使用 T 型账户来表示这些分类账，因为它们形状像字母 T，左侧为借方，右侧为贷方。
Each transaction is entered twice: once as a debit in one T-account and once as a credit in another. For example, if a business buys equipment for cash $2,000, the Equipment account (an asset) is debited and the Cash account (also an asset) is credited.
每笔交易都记入两次：一次作为借方记入一个 T 型账户，一次作为贷方记入另一个账户。例如，如果企业用 $2,000 现金购买设备，设备账户（资产）记借，现金账户（也是资产）记贷。
At the end of a period, each T-account is balanced. The difference between the total debits and total credits is called the balance carried down (c/d) and is brought down (b/d) to the next period.
在期末，每个 T 型账户要结平。总借方与总贷方之间的差额称为结转余额 (c/d)，并转入下一期为期初余额 (b/d)。
6. Recording Business Transactions | 记录商业交易
Recording transactions begins with source documents such as sales invoices, purchase invoices, and receipts. Students learn to analyse each transaction using the accounting equation and double-entry rules before making entries.
记录交易始于原始凭证，例如销售发票、采购发票和收据。学生学会在记账前运用会计等式和复式规则分析每一笔交易。
Common transactions include: capital introduced by the owner, purchases of inventory, sales of goods, payment of expenses, receipts from credit customers, and payments to suppliers. Each requires identifying the two accounts affected and applying the correct debit or credit.
常见交易包括：所有者投入资本、购买存货、销售商品、支付费用、收到赊销客户款项、向供应商付款。每项都需要识别受影响的账户，并正确应用借方或贷方。
For instance, a cash sale of goods records a debit to Cash (asset increase) and a credit to Sales (income increase). A payment of rent records a debit to Rent Expense (expense increase) and a credit to Cash (asset decrease).
例如，现金销售商品记录为借记现金（资产增加）和贷记销售收入（收入增加）。支付租金时，借记租金费用（费用增加）和贷记现金（资产减少）。
7. The Trial Balance | 试算平衡表
A trial balance is a list of all the ledger account balances at a particular date, separated into debit and credit columns. Its main purpose is to check the arithmetic accuracy of the double-entry records: total debits must equal total credits.
试算平衡表是在特定日期将所有分类账账户余额列出，分别填列在借方和贷方栏中。其主要目的是检查复式记录的算术准确性：借方总额必须等于贷方总额。
If the trial balance agrees, it provides some assurance that the double-entry rules have been applied correctly. However, a balanced trial balance does not guarantee that there are no errors — errors of omission, commission, principle, and compensating errors can still exist.
如果试算平衡表平衡，可以在一定程度上确保复式规则被正确运用。然而，试算平衡表平衡并不保证没有错误——遗漏错误、记账错误、原则错误和抵销错误仍然可能存在。
Students are often asked to prepare a trial balance from a list of balances or from T-accounts. They must remember that asset and expense accounts usually have debit balances, while liability, capital and income accounts usually have credit balances.
学生经常被要求根据余额列表或 T 型账户编制试算平衡表。他们必须记住，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。
8. Preparing the Income Statement | 编制利润表
The income statement (or profit and loss account) shows the financial performance of a business over a period of time. It reports revenues earned and expenses incurred, arriving at a net profit or net loss.
利润表（或损益表）显示企业在一段时间内的财务业绩。它报告所获得的收入和发生的费用，最终得出净利润或净亏损。
The basic format for Year 9 is: Sales less Cost of Sales gives Gross Profit. Then subtract other operating expenses (such as rent, wages, and utilities) to find Net Profit. Cost of Sales is calculated as Opening Inventory plus Purchases less Closing Inventory.
Year 9 的基本格式是：销售收入减去销售成本得出毛利。再减去其他营业费用（如租金、工资和水电费）以得出净利润。销售成本的计算公式是：期初存货加本期采购减期末存货。
When preparing an income statement from a trial balance, all income accounts are transferred to the credit of the income statement, and all expense accounts are transferred to the debit side. The balancing figure is profit (if credit side exceeds debit side) or loss (if debit side exceeds credit side).
根据试算平衡表编制利润表时，所有收入账户转入利润表的贷方，所有费用账户转入借方。平衡差额若为贷方大于借方，则为利润；若借方大于贷方，则为亏损。
9. The Statement of Financial Position | 财务状况表
The statement of financial position (traditionally called a balance sheet) shows the assets, liabilities, and capital of a business at a specific point in time. It is a snapshot of the accounting equation in action.
财务状况表（传统称为资产负债表）展示企业在某一特定时点的资产、负债和资本状况。它是会计等式实际运用的快照。
Assets are classified as non-current (long-term, e.g. equipment, vehicles) and current (short-term, e.g. cash, inventory, trade receivables). Liabilities are similarly classified as non-current (long-term loans) and current (trade payables, bank overdraft).
资产分为非流动（长期，如设备、车辆）和流动（短期，如现金、存货、应收账款）。负债同样分为非流动（长期贷款）和流动（应付账款、银行透支）。
Capital at the end of the period equals opening capital plus additional capital introduced plus net profit less drawings. This closing capital figure must equal total assets minus total liabilities, confirming the accounting equation.
期末资本等于期初资本加新增资本投入加净利润减提款。这一期末资本数必须等于总资产减总负债，从而验证会计等式。
10. Essential Accounting Concepts | 核心会计概念
Edexcel expects students to understand several fundamental accounting concepts that underpin the preparation of financial statements. These concepts ensure consistency, reliability, and comparability of accounting information.
Edexcel 期望学生理解支撑财务报表编制的几个基本会计概念。这些概念确保会计信息的一致性、可靠性和可比性。
The business entity concept states that the business is treated as separate from its owner. Only the business's transactions are recorded, never the owner's personal affairs. The money measurement concept says that only information that can be expressed in monetary terms is recorded.
商业实体概念指出，企业被视为独立于其所有者。只记录企业的交易，绝不记录所有者的个人事务。货币计量概念表明，只有能够以货币形式表达的信息才被记录。
The historical cost concept requires assets to be recorded at their original purchase price, not at a revalued amount. Going concern assumes the business will continue to operate for the foreseeable future. The prudence concept dictates that expenses and liabilities should be recognised as soon as possible, but revenues only when realised.
历史成本概念要求资产以其原始购买价格入账，而非重估价值。持续经营假设企业在可预见的未来将继续运营。谨慎性概念规定，费用和负债应尽快确认，但收入只有在实现时才确认。
The consistency concept requires using the same accounting methods from one period to the next, so that comparisons are meaningful. Students should be able to explain each concept and identify examples.
一致性概念要求各期间采用相同的会计方法，以便进行有意义的比较。学生应能解释每个概念并举出例子。
11. Balancing and Closing Accounts | 结平与结账
At the end of a financial period, ledger accounts are balanced to find the closing balance on each account. For asset and expense accounts, this is typically a debit balance; for liability, capital and income accounts, a credit balance.
在财务期末，分类账账户要结平，以找出每个账户的期末余额。对于资产和费用账户，这通常是借方余额；对于负债、资本和收入账户，通常是贷方余额。
The balancing process: total both sides of the T-account, enter the difference as the balance carried down (c/d) on the smaller side so that both sides equal. Then bring that balance down (b/d) on the opposite side for the next period.
结平过程：加总 T 型账户的双方，将差额作为结转余额 (c/d) 填入金额较小的一边，使两边相等。然后在下一期的相反方向作为期初余额 (b/d) 转入。
Income and expense accounts are not simply carried forward — they are closed to the income statement. This means their balances are transferred to the trading and profit and loss account, leaving a zero balance ready for the next period.
收入和费用账户不会直接结转——它们被结转到利润表。这意味着它们的余额被转入损益账户，账户余额归零，为下一期做好准备。
12. Exam Tips and Common Mistakes | 考试技巧与常见错误
Many marks are lost through simple mistakes. Always double-check that every transaction has a debit and a credit of equal value. When posting to T-accounts, clearly label each entry with the other account name (the "cross-reference") to avoid confusion.
许多分数因简单错误而丢失。务必检查每笔交易是否有等值的借方和贷方。在过账到 T 型账户时，清楚标注每笔分录的另一账户名称（“交叉索引”），以避免混淆。
When preparing a trial balance, carefully list balances in the correct debit or credit column. If it does not balance, look for common errors: missing a balance, placing an item in the wrong column, or arithmetic mistakes in the addition or in individual account balancing.
在编制试算平衡表时，仔细将余额列在正确的借方或贷方栏中。如果不平衡，查找常见错误：遗漏某个余额、项目放错栏、加法错误或单个账户结平中的算术错误。
For the income statement, remember that carriage inwards is part of the cost of sales, while carriage outwards is a selling expense. Also, do not confuse accruals and prepayments — though these may be introduced only briefly in Year 9, a basic awareness is helpful.
在利润表中，请牢记购货运费是销售成本的一部分，而销货运费是销售费用。同时，不要混淆应计费用和预付款项——尽管 Year 9 可能只是简单提及，但基本了解会很有帮助。
Finally, in the statement of financial position, ensure that net profit from the income statement is added to capital, and drawings are deducted. Always verify that total assets equal total liabilities plus capital — this is the ultimate check.
最后，在财务状况表中，确保将利润表中的净利润加入到资本中，并减去提款。始终验证总资产等于总负债加资本——这是最终的检查。
