1. Basic Accounting Concepts and the Accounting Equation | 会计基本概念与会计等式
Accounting is the systematic process of recording, classifying, and summarising financial transactions to provide information that is useful for decision making. The entire subject is built on the accounting equation, which shows the relationship between a business's resources and the claims against those resources.
会计是对财务交易进行系统性记录、分类与汇总，从而为决策提供有用信息的过程。整门学科都建立在会计等式之上，这个等式揭示了企业资源与对这些资源的要求权之间的关系。
Assets = Liabilities + Owner's Equity
资产 = 负债 + 所有者权益
Assets are what the business owns or controls, such as cash, inventory, and equipment. Liabilities represent what the business owes to outside parties, like bank loans and trade payables. Owner's equity is the owner's residual claim on the assets after all liabilities have been settled. This equation must always balance, meaning every transaction has a dual effect that keeps both sides equal.
资产是企业拥有或控制的资源，比如现金、存货和设备。负债代表企业欠外部各方的款项，如银行贷款和应付账款。所有者权益是扣除所有负债后所有者对资产的剩余索取权。这个等式必须始终保持平衡，也就是说，每笔交易都会产生双重影响，使得等式两边总是相等。
2. Assets, Liabilities and Owner's Equity | 资产、负债与所有者权益
Assets are commonly divided into current assets and non-current assets. Current assets are expected to be turned into cash or used up within one year, such as cash at bank, accounts receivable, and inventory. Non-current assets are held for long-term use, including land, buildings, machinery, and vehicles.
资产通常分为流动资产和非流动资产。流动资产预计在一年内变现或消耗，比如银行存款、应收账款和存货。非流动资产是用于长期使用的资产，包括土地、建筑物、机器和车辆。
Liabilities are similarly classified. Current liabilities are obligations due within one year, for example trade payables, bank overdrafts, and short-term loans. Non-current liabilities are debts that extend beyond one year, such as mortgages and long-term bank loans.
负债也采用类似的分类方式。流动负债是将在一年内到期的义务，例如应付账款、银行透支和短期借款。非流动负债是期限超过一年的债务，如按揭贷款和长期银行借款。
Owner's equity represents the owner's investment in the business plus any profits retained in the business. It increases when the owner contributes capital or the business earns a profit, and decreases when the owner makes drawings or the business incurs a loss. This is often recorded in the capital account and retained earnings.
所有者权益代表所有者对企业的投资加上留存在企业的利润。当所有者投入资本或企业实现利润时，所有者权益会增加；当所有者提款或企业发生亏损时，所有者权益会减少。这部分通常记录在资本账户和留存收益中。
3. Revenue and Expenses | 收入与费用
Revenue is the income earned by a business from its normal operating activities, such as sales of goods or services. Revenue increases owner's equity and is recorded when it is earned, not necessarily when cash is received, following the accrual concept.
收入是企业从其正常经营活动中赚取的所得，比如销售商品或服务。收入会增加所有者权益，并且是按照权责发生制在赚得时记录，而未必在实际收到现金时记录。
Expenses are the costs incurred to generate revenue. Examples include rent, wages, electricity, and the cost of goods sold. Expenses decrease owner's equity because they represent resources consumed or liabilities incurred in the process of earning revenue.
费用是为产生收入而发生的成本。例子包括租金、工资、电费和已售商品成本。费用会减少所有者权益，因为它们代表了在赚取收入过程中消耗的资源或产生的负债。
The relationship between revenue and expenses determines whether the business makes a profit. When total revenue exceeds total expenses, the result is a net profit, which increases owner's equity. If expenses exceed revenue, the business suffers a net loss, reducing equity.
收入与费用的关系决定了企业是否盈利。当总收入超过总费用时，就产生了净利润，从而增加所有者权益。如果费用超过收入，企业就会发生净亏损，所有者权益也会随之减少。
Net Profit = Revenue - Expenses
净利润 = 收入 - 费用
4. The Double-Entry System | 复式记账系统
Double-entry bookkeeping is the method used to record financial transactions. Every transaction affects at least two accounts, with one account receiving a debit entry and another receiving a credit entry. The total value of debits must always equal the total value of credits.
复式记账是记录财务交易的方法。每笔交易至少影响两个账户，其中一个账户记入借方，另一个账户记入贷方。借方总金额必须始终等于贷方总金额。
Total Debits = Total Credits
借方总额 = 贷方总额
The rules for debits and credits are based on the accounting equation. Assets increase with a debit and decrease with a credit. Liabilities and owner's equity increase with a credit and decrease with a debit. Since revenue increases equity, revenue accounts increase with a credit; expense accounts increase with a debit because they reduce equity.
借方和贷方的规则源于会计等式。资产增加记借方，减少记贷方。负债和所有者权益增加记贷方，减少记借方。由于收入增加权益，收入账户增加记贷方；费用账户增加记借方，因为费用会减少权益。
For example, when a business buys inventory for cash, the inventory account (asset) is debited to record the increase, and the cash account (asset) is credited to record the decrease. Both sides remain balanced, and the dual effect is captured accurately.
例如，当企业用现金购买存货时，存货账户（资产）记借方反映增加，现金账户（资产）记贷方反映减少。两边保持平衡，双重影响被准确记录。
5. Journals and Ledgers | 日记账与分类账
Transactions are first recorded in a book of original entry called a journal. The general journal records non‑routine transactions and includes the date, accounts affected, amounts, and a brief narration. It shows the debit and credit effects clearly before the information is transferred to the ledger.
交易首先记录在被称为日记账的原始记录簿中。普通日记账记录非常规交易，包含日期、受影响的账户、金额和简要说明。在将信息转入分类账之前，它能清晰地显示借方和贷方的影响。
The ledger is a collection of accounts where all transactions affecting a particular asset, liability, equity, revenue, or expense are gathered. Each account has a T‑format with a left (debit) side and a right (credit) side. After journalising, the entries are posted to the appropriate ledger accounts, and running balances are calculated.
分类账是账户的集合，所有影响特定资产、负债、权益、收入或费用的交易都汇总于此。每个账户采用T型格式，左边是借方，右边是贷方。在日记账中记录后，分录被过入对应的分类账账户，并计算结余。
A business may also use special journals for repetitive transactions, such as a sales journal for credit sales and a purchases journal for credit purchases. However, at Year 9 CCEA level, the focus is mainly on the general journal and the general ledger.
企业还可以使用特殊日记账来处理重复性交易，例如销售日记账记录赊销，采购日记账记录赊购。不过，在 CCEA Year 9 阶段，重点主要放在普通日记账和总分类账上。
6. The Trial Balance | 试算平衡表
A trial balance is a list of all the ledger accounts and their closing balances at a particular date. The debit balances are recorded in one column and the credit balances in another. Its main purpose is to check the arithmetical accuracy of the double‑entry records by ensuring that total debits equal total credits.
试算平衡表是截至某一特定日期所有分类账账户及其期末余额的列表。借方余额列在一栏，贷方余额列在另一栏。其主要目的是通过验证借方总额等于贷方总额，检查复式记账记录在算术上是否正确。
If the trial balance balances, it suggests that the double‑entry principles have been applied correctly, though errors such as omission of an entire transaction or compensating errors could still exist. If it does not balance, it indicates that a mistake has occurred that must be investigated and corrected.
如果试算平衡表平衡，意味着复式记账原则得到了正确应用，但仍可能存在诸如整笔交易漏记或抵销性错误等问题。如果试算平衡表不平衡，则说明存在错误，必须进行调查和更正。
Preparing a trial balance is a vital step in the accounting cycle before drafting the income statement and balance sheet. It organises the account balances in one place and makes it easier to prepare the final financial statements.
在编制利润表和资产负债表之前，试算平衡表的编制是会计循环中至关重要的一步。它将所有账户余额整理在一起，使最终的财务报表编制更加便捷。
7. The Income Statement | 利润表
An income statement, also called a profit and loss account, summarises the revenues earned and expenses incurred over a specific period, typically a year. It shows whether the business has generated a net profit or a net loss during that time.
利润表，也称损益表，汇总了企业在一定期间（通常为一年）内取得的收入和发生的费用。它列示了企业在此期间实现了净利润还是净亏损。
Trading businesses often prepare a two‑section income statement. The trading account calculates gross profit by deducting cost of goods sold from sales revenue. The profit and loss account then subtracts other operating expenses from gross profit to arrive at net profit.
贸易型企业通常编制包含两个部分的利润表。购销部分通过从销售收入中扣除已售商品成本来计算毛利；损益部分再从毛利中减去其他经营费用，得出净利润。
Gross Profit = Sales - Cost of Goods Sold
毛利 = 销售收入 - 已售商品成本
Expenses such as wages, rent, insurance, and depreciation are listed in the profit and loss section. The final figure, net profit, is transferred to the owner's equity section of the balance sheet, linking the two key financial statements.
工资、租金、保险费和折旧等费用列示在损益部分。最终得出的净利润将转入资产负债表的所有者权益部分，从而将这两张主要财务报表联系起来。
8. The Balance Sheet | 资产负债表
A balance sheet, or statement of financial position, shows the assets, liabilities, and owner's equity of a business at a specific point in time. It is a snapshot of the financial condition and is structured according to the accounting equation.
资产负债表展示企业在某一特定时点的资产、负债和所有者权益。它是一幅反映财务状况的快照，并且是按照会计等式的结构来编排的。
Assets are usually presented in order of liquidity, starting with current assets such as cash and inventory, followed by non‑current assets like property and equipment. Liabilities are similarly listed, with current liabilities presented before non‑current liabilities.
资产通常按流动性排列，先是现金和存货等流动资产，之后是房产和设备等非流动资产。负债也按类似方式列示，流动负债排在非流动负债之前。
Owner's equity represents the owner's capital account balance plus any retained profits from the income statement, less drawings. The balance sheet confirms that the dual‑aspect principle holds true, as total assets always equal total liabilities plus owner's equity.
所有者权益代表了所有者的资本账户余额加上利润表中的留存利润，减去提款。资产负债表印证了双重性原则，因为总资产始终等于总负债加上所有者权益。
Total Assets = Total Liabilities + Owner's Equity
总资产 = 总负债 + 所有者权益
9. The Accounting Cycle | 会计周期
The accounting cycle is the sequence of steps followed to record, classify, and summarise financial data during an accounting period. In a simplified form suitable for Year 9, the cycle typically includes identifying transactions, recording them in journals, posting to the ledger, preparing a trial balance, drafting the income statement and balance sheet, and closing off temporary accounts.
会计周期是在一个会计期间内记录、分类和汇总财务数据所遵循的一系列步骤。适用于 Year 9 的简化形式通常包括：识别交易、在日记账中记录、过账至分类账、编制试算平衡表、草拟利润表和资产负债表，以及结清临时性账户。
The process begins when source documents such as receipts or invoices provide evidence of a transaction. These are used to make journal entries that show the debit and credit effects. The journal entries are then posted to the relevant T‑accounts in the ledger, and a trial balance is extracted to verify accuracy.
这一过程始于收据或发票等原始凭证提供交易证据。利用这些凭证编制显示借贷影响的日记账分录。随后，日记账分录被过入分类账中相关的T型账户，并编制试算平衡表以验证准确性。
Once the trial balance is confirmed, the income statement is prepared to calculate profit, and the balance sheet is then drafted to show the financial position. At the end of the period, revenue and expense accounts are closed to the capital account, readying the books for the next cycle.
试算平衡表确认无误后，编制利润表以计算利润，接着草拟资产负债表以反映财务状况。期末时，收入和费用账户结转入资本账户，从而为下一周期的账务做好准备。
10. Common Errors and How to Correct Them | 常见错误及其更正方法
Even careful students can make errors when recording transactions. Common mistakes include transposition errors (switching digits, such as recording 54 instead of 45), omission of a transaction entirely, posting a correct amount to the wrong account, or recording a debit and credit for unequal amounts. These can cause the trial balance to be out of balance.
即使是细心的学生，在记录交易时也可能犯错。常见错误包括换位错误（数字位置颠倒，例如将 45 记为 54）、完全漏记交易、将正确金额过入错误账户，或者记录的借方与贷方金额不相等。这些错误会导致试算平衡表不平衡。
If the trial balance does not balance, first check the addition of the debit and credit columns. Then compare the trial balance figures with the ledger account balances to ensure they have been copied correctly. Look for a difference that could reveal a missing entry; sometimes the difference divided by 2 hints at a debit posted as a credit or vice versa.
如果试算平衡表不平衡，首先检查借方栏和贷方栏的加总。然后将试算平衡表上的数字与分类账账户余额进行比对，确保抄写无误。寻找差额可能暗示遗漏的分录；有时差额除以 2 能提示一笔借记误记为贷记，反之亦然。
Once the error is located, a correcting journal entry must be made. This entry follows the same double‑entry rules, debiting and crediting the appropriate accounts to rectify the mistake. After posting the correction, a new trial balance should be prepared to confirm that the books are once again in balance.
找到错误后，必须编制更正分录。该分录遵循相同的复式记账规则，对相应账户进行借记和贷记以修正错误。过账更正后，应重新编制试算平衡表，以确认账簿再次达到平衡。
