1. Introduction to Accounting and Its Purpose | 会计的定义与目的
Accounting is the systematic process of recording, summarising, and reporting financial transactions to provide useful information for decision-making. It helps businesses track their income and expenses, assess profitability, and ensure they are managing resources effectively. Without accurate accounting, owners, managers, and investors would be unable to make informed financial decisions.
会计是系统记录、汇总和报告财务交易的过程，为决策提供有用信息。它帮助企业追踪收入与支出、评估盈利能力，并确保有效管理资源。没有精准的会计，企业主、管理者和投资者将无法做出明智的财务决策。
The main purposes of accounting include keeping a permanent record of all transactions, measuring financial performance, safeguarding assets, and complying with legal requirements such as tax filings. It also provides information for budgeting, cost control, and strategic planning.
会计的主要目的包括永久保存所有交易记录、衡量财务业绩、保护资产，以及遵守纳税申报等法律要求。它还为预算编制、成本控制和战略规划提供信息。
2. The Accounting Equation | 会计等式
The accounting equation is the foundation of double-entry bookkeeping: Assets = Liabilities + Equity. This formula always balances because every business resource (asset) is funded either by borrowing (liabilities) or by the owner’s investment and retained profits (equity).
会计等式是复式记账的基础：资产 = 负债 + 所有者权益。这一等式始终平衡，因为每一项企业资源（资产）要么通过借款（负债）获得，要么来自业主投入和留存收益（权益）。
Equity can be expanded to include capital, revenues, expenses, and drawings: Equity = Opening Capital + Revenues − Expenses − Drawings. Therefore, when a business generates revenue, equity increases; when it incurs expenses, equity decreases. This interrelationship means every transaction has at least two effects that keep the equation in balance.
权益可进一步展开为：权益 = 期初资本 + 收入 − 费用 − 提款。因此，企业获得收入时权益增加；发生费用时权益减少。这种相互关系意味着每笔交易至少产生两个影响，使等式始终保持平衡。
3. Assets, Liabilities, and Equity | 资产、负债与所有者权益
Assets are resources owned by a business that have future economic value. They are classified as non-current (long-term) assets, such as buildings and machinery, and current assets like cash, inventory, and accounts receivable that are expected to be converted into cash within a year.
资产是企业拥有、具有未来经济价值的资源，分为非流动（长期）资产，如建筑物和设备，以及流动资产，如现金、存货和应收账款，这些预计在一年内变现。
Liabilities represent present obligations arising from past events. Non-current liabilities include long-term borrowings, while current liabilities are due within one year, such as trade payables and overdrafts. Equity is the residual interest in the assets after deducting all liabilities, often described as the owner’s claim on the business.
负债代表因过去事项产生的现时义务。非流动负债包括长期借款，而流动负债在一年内到期，如应付账款和银行透支。所有者权益是扣除所有负债后对资产的剩余权益，常被描述为业主对企业资产的索求权。
4. Double-Entry Bookkeeping Basics | 复式记账基础
Every financial transaction has a dual effect, meaning it impacts at least two accounts. For example, if a business buys equipment with cash, the equipment account increases while the cash account decreases. This system ensures the accounting equation remains in balance and provides a complete picture of financial events.
每笔财务交易都具有双重影响，即至少涉及两个账户。例如，企业用现金购买设备，设备账户增加，现金账户减少。这一系统确保会计等式始终保持平衡，并完整反映了财务事件。
Transactions are recorded in individual accounts kept in ledgers. Each account has a left side (debit) and a right side (credit). The recording process follows specific rules depending on the account type, which we will explore in the next section.
交易被记录在分类账的各账户中。每个账户都有左侧（借方）和右侧（贷方）。记录过程根据账户类型遵循特定规则，我们将在下一节探讨。
5. Debits and Credits Explained | 借贷记账法
In accounting, ‘debit’ and ‘credit’ do not simply mean increase or decrease; their effect depends on the type of account. A helpful memory aid is DEAD CLIC: Debit Expenses, Assets, Drawings; Credit Liabilities, Income, Capital. This rule applies because assets, expenses, and drawings normally have debit balances, while liabilities, income, and capital normally have credit balances.
在会计中，“借”和“贷”并不简单地表示增加或减少；其影响取决于账户类型。一个有用的记忆法是 DEAD CLIC：费用、资产、提款记借方；负债、收入、资本记贷方。这条规则适用是因为资产、费用和提款通常有借方余额，而负债、收入和资本通常有贷方余额。
For asset accounts, an increase is a debit and a decrease is a credit. For liability and equity accounts, an increase is a credit and a decrease is a debit. Revenue increases equity, so it is credited; expenses decrease equity, so they are debited. Mastering this logic is essential for accurate bookkeeping.
对于资产账户，增加记借方，减少记贷方。对于负债和权益账户，增加记贷方，减少记借方。收入增加权益，因此记贷方；费用减少权益，因此记借方。掌握这一逻辑对于准确记账至关重要。
6. Recording Transactions in T-Accounts | 使用T型账户记录交易
A T-account is a simple visual tool used to illustrate ledger accounts. The left side is the debit side, and the right side is the credit side. Let’s record a cash sale of £500. Cash (asset) increases, so we debit Cash; Sales Revenue (income) increases, so we credit Sales Revenue.
T型账户是用于展示分类账的简易可视化工具。左侧为借方，右侧为贷方。让我们记录一笔500英镑的现金销售。现金（资产）增加，因此借记现金；销售收入（收入）增加，因此贷记销售收入。
| Dr Cash | Cr Cash |
|---|---|
| Sales 500 |
| Dr Sales Revenue | Cr Sales Revenue |
|---|---|
| Cash 500 |
The above T-accounts show that the Cash account receives a debit entry of £500, while the Sales Revenue account receives a credit entry of £500. The total debits equal total credits, maintaining the balance.
以上T型账户显示，现金账户收到500英镑的借方分录，而销售收入账户收到500英镑的贷方分录。借方总额等于贷方总额，保持了平衡。
Consider another example: the business pays £200 for rent by cheque. Rent Expense increases (debit) and Bank decreases (credit). Practising such entries builds fluency in double-entry recording.
再举一例：企业用支票支付租金200英镑。租金费用增加（借记），银行存款减少（贷记）。练习此类分录能提高复式记账的熟练度。
7. The Trial Balance | 试算平衡表
A trial balance is a list of all ledger accounts and their closing balances at a specific date, with debit balances in one column and credit balances in another. Its purpose is to check the arithmetic accuracy of the double-entry system. If total debits equal total credits, the accounting equation is theoretically in balance.
试算平衡表是特定日期所有分类账户及其结余的列表，借方余额列于一栏，贷方余额列于另一栏。其目的是检查复式记账系统的算术准确性。若借方合计等于贷方合计，则会计等式理论上平衡。
Below is a simplified trial balance for a small business as at 31 December:
以下是一家小型企业截至12月31日的简化试算平衡表：
| Account | Debit (£) | Credit (£) |
|---|---|---|
| Cash | 3,000 | |
| Equipment | 7,000 | |
| Trade Payables | 2,500 | |
| Capital | 5,000 | |
| Sales Revenue | 8,000 | |
| Rent Expense | 1,500 | |
| Drawings | 4,000 | |
| Totals | 15,500 | 15,500 |
In this trial balance, total debits (15,500) equal total credits (15,500), so there is no obvious arithmetic error. However, a balanced trial balance does not guarantee that all entries are correct; errors of omission, commission, or principle may still exist.
在此试算平衡表中，借方合计（15,500）等于贷方合计（15,500），因此没有明显的算术错误。然而，平衡的试算平衡表并不能保证所有分录正确；漏记、过账错误或原则性错误仍可能存在。
8. Introduction to the Income Statement | 利润表简介
The income statement (also known as the profit and loss account) summarises a business’s revenues and expenses over a period of time, such as a month or a year. The basic formula is: Net Profit = Total Revenues − Total Expenses. If revenues exceed expenses, the business makes a profit; if expenses are higher, it incurs a loss.
利润表（亦称损益表）汇总企业在一段时期（如一个月或一年）内的收入和费用。基本公式为：净利润 = 总收入 − 总费用。若收入大于费用，企业盈利；若费用更高，则发生亏损。
Using the trial balance figures from the previous section, the income statement would show: Sales Revenue £8,000 − Rent Expense £1,500 = Net Profit £6,500 (ignoring other possible expenses for simplicity). This profit is then transferred to the equity section of the statement of financial position.
运用上一节试算平衡表中的数据，利润表将显示：销售收入8,000英镑 − 租金费用1,500英镑 = 净利润6,500英镑（为简化起见忽略其他可能费用）。该利润随后转入财务状况表的权益部分。
