1. What is Accounting? | 什么是会计？
Accounting is the process of recording, classifying, summarising, and interpreting financial information. It provides a clear picture of a business’s financial health and helps owners, managers, and investors make informed decisions. At its heart, accounting answers two key questions: Is the business making a profit? and What does the business own and owe?
会计是记录、分类、汇总和解释财务信息的过程。它清晰地描绘了企业的财务健康状况，帮助所有者、管理者和投资者做出明智的决策。从根本上说，会计回答两个关键问题：企业是否盈利？以及企业拥有什么和欠什么？
In the Cambridge curriculum, Year 9 introduces these ideas through simple business scenarios. You will learn how transactions are recorded systematically rather than being kept as informal notes. This systematic approach ensures accuracy and allows stakeholders to compare performance over time.
在剑桥课程中，Year 9 通过简单的商业场景引入这些概念。你将学习如何系统地记录交易，而不是以非正式的笔记留存。这种系统的方法可以确保准确性，并使利益相关者能够比较不同时期的表现。
2. The Accounting Equation | 会计等式
Every transaction in accounting rests on a fundamental relationship known as the accounting equation. This equation must always balance, no matter how many transactions take place. It is the foundation for the double-entry system and the statement of financial position.
会计中的每一笔交易都建立在一个被称为会计等式的基本关系之上。无论发生多少交易，该等式必须始终保持平衡。它是复式记账体系和财务状况表的基础。
Assets = Liabilities + Owner’s Equity
资产 = 负债 + 所有者权益
Assets are resources controlled by the business, such as cash, inventory, and equipment. Liabilities represent what the business owes to outsiders, for example bank loans or trade payables. Owner’s equity is the residual interest, showing the owner’s claim on the assets after all liabilities are paid. If a business owns $10,000 in assets and owes $4,000, the owner’s equity is $6,000.
资产是企业控制的资源，例如现金、存货和设备。负债代表企业欠外部方面的款项，比如银行贷款或应付账款。所有者权益是剩余权益，显示在偿还所有负债后所有者对资产的索取权。如果一家企业拥有 10,000 美元资产并承担 4,000 美元负债，那么所有者权益就是 6,000 美元。
3. Assets, Liabilities, and Owner’s Equity | 资产、负债与所有者权益
To use the accounting equation effectively, you need to recognise different types of assets and liabilities. Assets are split into non-current assets (kept for more than one year, like machinery and buildings) and current assets (held for a short term, such as cash, inventory, and trade receivables).
要有效运用会计等式，你需要辨识不同类型的资产和负债。资产分为非流动资产（持有超过一年，如机器和建筑物）和流动资产（短期持有，如现金、存货和应收账款）。
Liabilities also have two categories. Non-current liabilities are debts that are due after more than one year, like a long-term bank loan. Current liabilities are obligations that must be settled within one year, for instance trade payables and bank overdrafts. Owner’s equity includes the original capital invested and retained profits accumulated over time.
负债也有两类。非流动负债是指一年以后到期的债务，如长期银行贷款。流动负债是必须在一年内清偿的债务，例如应付账款和银行透支。所有者权益包括最初投入的资本和随时间累积的留存利润。
4. The Double-Entry System | 复式记账体系
The double-entry system is the standard method used to record accounting transactions. Every transaction affects at least two accounts – one account receives a debit entry and another receives a credit entry. The total value of debit entries must always equal the total value of credit entries, keeping the accounting equation in balance.
复式记账体系是记录会计交易的标准方法。每一笔交易至少影响两个账户——一个账户记录借方，另一个账户记录贷方。借方总额必须始终等于贷方总额，以保持会计等式的平衡。
This system is powerful because it provides a built-in check for errors. If the debits do not equal the credits, you know a mistake has been made. Double entry also allows a business to track not just the overall effect of a transaction but also where the money came from and where it went.
这一体系非常有效，因为它内置了查错功能。如果借方不等于贷方，你就知道出错了。复式记账还能让企业不仅跟踪交易的整体影响，还能追踪资金的来源和去向。
5. Rules of Debit and Credit | 借贷记账规则
Many beginners find debit and credit confusing, but a clear set of rules makes them easy to master. The terms ‘debit’ (Dr) and ‘credit’ (Cr) simply refer to the left side and right side of an account. The rule depends on the type of account.
许多初学者觉得借和贷容易混淆，但一套清晰的规则可以使它们易于掌握。术语’借方'(Dr) 和 ‘贷方'(Cr) 仅指账户的左方和右方。规则取决于账户的类型。
For assets and expenses, an increase is recorded on the debit side, and a decrease is on the credit side. For liabilities, income, and capital, it works the opposite way: an increase is a credit, and a decrease is a debit. A useful memory aid is ‘DEAD CLIC’: Debit increases in Expenses, Assets, Drawings; Credit increases in Liabilities, Income, Capital.
对于资产和费用，增加记录在借方，减少记录在贷方。对于负债、收入和资本，则相反：增加记贷方，减少记借方。一个有用的记忆方法是’DEAD CLIC’：借方增加费用、资产、提款；贷方增加负债、收入、资本。
When you pay cash for rent, Cash (asset) decreases – credit Cash; Rent Expense increases – debit Rent Expense. The two sides stay equal. Always think about which accounts are involved and whether each is increasing or decreasing.
当你支付现金用于租金时，现金（资产）减少——贷记现金；租金费用增加——借记租金费用。两边保持相等。要始终考虑涉及哪些账户，以及各自是增加还是减少。
6. Ledger Accounts and T-Accounts | 分类账和T型账户
A ledger account is a detailed record of all transactions affecting a particular item, such as cash, sales, or inventory. The simplest way to visualise a ledger account is by using a T-account. It has a left side for debits and a right side for credits, shaped like the letter T.
分类账账户是对影响某一特定项目（如现金、销售收入或存货）的所有交易进行详细记录。可视化分类账账户最简单的方法是使用 T 型账户。它左边是借方，右边是贷方，形状像字母 T。
Below is a typical T-account for the Cash account after the business receives $5,000 from the owner and later pays $2,000 for equipment:
下面是一个典型的现金 T 型账户，假设企业从所有者处收到 5,000 美元，随后支付 2,000 美元购买设备：
| Dr Cash Cr | |
|---|---|
| Capital $5,000 | Equipment $2,000 |
In this example, the debit side records the $5,000 received, and the credit side records the $2,000 paid out. The account is not yet balanced; we will see how to balance it in a later section.
在这个例子中，借方记录了收到的 5,000 美元，贷方记录了支付的 2,000 美元。该账户尚未结平；我们将在后面小节看到如何结平。
7. Recording Simple Transactions | 记录简单交易
Year 9 students are expected to record common business transactions using the double-entry framework. Let’s look at four typical entries. A business starts when the owner introduces $10,000 cash: debit Cash, credit Capital. Then it buys goods for $3,000 cash: debit Inventory, credit Cash.
Year 9 学生需要能够使用复式记账框架记录常见的商业交易。让我们看四个典型分录。企业启动时，所有者投入 10,000 美元现金：借记现金，贷记资本。然后以 3,000 美元现金购买商品：借记存货，贷记现金。
If the business buys inventory on credit for $2,500, we debit Inventory and credit Trade Payables. When it later sells half of the goods for $4,000 cash, we record two legs: debit Cash $4,000, credit Sales Revenue $4,000; and also debit Cost of Sales $2,500, credit Inventory $2,500. This double movement reflects both revenue earned and the reduction in stock.
如果企业赊购 2,500 美元存货，我们借记存货，贷记应付账款。当它后来以 4,000 美元现金出售一半商品时，我们记录两条线：借记现金 4,000 美元，贷记销售收入 4,000 美元；同时借记销售成本 2,500 美元，贷记存货 2,500 美元。这种双重变动反映了赚取的收入和存货的减少。
Every time, check that the total debits equal the total credits for the transaction. This habit will prevent many mistakes when you move on to more complex topics.
每次都要检查交易的借方总额是否等于贷方总额。养成这个习惯，可以避免在学习更复杂的主题时出现许多错误。
8. Balancing Off Accounts | 结平账户
At the end of a period, ledger accounts must be balanced off to find the final balance. Balancing off means calculating the difference between the debit and credit sides and entering that difference on the smaller side as a balance carried down (c/d). The same figure is then brought down (b/d) on the opposite side as the opening balance for the next period.
在一个期间结束时，分类账账户必须结平以求出期末余额。结平意味着计算借方和贷方的差额，并将该差额以结转余额 (c/d) 的形式填入较小的一侧。然后将相同数字以承前余额 (b/d) 的形式记入另一侧，作为下一期的期初余额。
Returning to our earlier Cash T-account with $5,000 debit and $2,000 credit: the debit side is larger by $3,000. We write “Balance c/d $3,000” on the credit side, then rule off both sides to make them equal at $5,000. Below the line, we enter “Balance b/d $3,000” on the debit side, showing the cash available for the next period. This process ensures every account is ready for the trial balance.
回到我们先前的现金 T 型账户，借方 5,000 美元、贷方 2,000 美元：借方比贷方多出 3,000 美元。我们在贷方写上’结平余额 c/d 3,000 美元’，然后划双线使两边都等于 5,000 美元。在双线下，我们在借方写上’承前余额 b/d 3,000 美元’，显示下一期间可用的现金。这个过程确保每个账户为试算表做好准备。
9. The Trial Balance | 试算表
A trial balance is a list of all the ledger accounts and their closing balances at a particular date. It is prepared to check the arithmetic accuracy of the double-entry records. If the total of debit balances equals the total of credit balances, the records are mathematically correct – though this does not guarantee that there are no errors of principle or omission.
试算表是某一特定日期所有分类账账户及其期末余额的列表。编制试算表是为了检查复式记账记录的算术准确性。如果借方余额总和等于贷方余额总和，则记录在算术上是正确的——尽管这并不能保证不存在原则性错误或遗漏错误。
A simple trial balance might look like this:
一个简单的试算表可能如下所示：
| Account | Debit $ | Credit $ |
|---|---|---|
| Cash | 3,000 | |
| Inventory | 2,500 | |
| Capital | 10,000 | |
| Sales Revenue | 4,000 | |
| Rent Expense | 1,500 | |
| Trade Payables | 2,000 | |
| Drawings | 500 |
If the totals match, we can confidently use the balances to prepare financial statements. If they differ, we must find and correct the discrepancy before proceeding.
如果合计数相符，我们可以自信地使用这些余额编制财务报表。如果合计数不等，我们必须找到并纠正差异，然后再继续。
10. Introduction to Financial Statements | 财务报表简介
Two key financial statements are prepared from the trial balance: the income statement and the statement of financial position. The income statement shows the business’s profit or loss over a period. Its simple structure is:
根据试算表可以编制两份关键财务报表：利润表和财务状况表。利润表显示企业在一段期间的盈利或亏损。其简单结构如下：
Revenue – Expenses = Net Profit
收入 – 费用 = 净利润
Revenue (or sales) represents the income earned from selling goods or services. Expenses include costs such as rent, wages, and electricity. If expenses exceed revenue, the result is a net loss. The net profit is then added to the owner’s equity in the statement of financial position.
收入（或销售收入）代表从销售商品或服务中赚取的收入。费用包括租金、工资和电费等成本。如果费用超过收入，结果就是净亏损。净利润随后会在财务状况表中被加到所有者权益里。
The statement of financial position, also called the balance sheet, presents the accounting equation at a single point in time. It lists assets on one side and liabilities plus owner’s equity on the other, demonstrating that the business’s resources equal its financing. For Year 9, you typically arrange assets and liabilities in order of liquidity or permanence.
财务状况表，也称资产负债表，反映某一时点的会计等式。它在一边列出资产，另一边列出负债加所有者权益，表明企业的资源等于其筹资来源。对于 Year 9 学生，你通常按照流动性或持久性顺序排列资产和负债。
11. Key Accounting Concepts | 关键会计概念
Cambridge Accounting introduces several fundamental concepts that guide how financial information is reported. Understanding these concepts helps you apply consistent judgement when recording transactions.
剑桥会计引入了若干基本概念，用以指导财务信息的报告方式。理解这些概念有助于你在记录交易时应用一致的判断。
The business entity concept states that the business is treated as separate from its owner. Only business transactions are recorded, not the owner’s personal expenses. The money measurement concept means we only record activities that can be expressed in monetary terms. The going concern concept assumes the business will continue operating in the foreseeable future, so assets are valued at cost rather than forced-sale values.
会计主体概念指出，企业被视为独立于其所有者。只记录企业交易，而不记录所有者的个人开支。货币计量概念意味着我们只记录能够用货币表达的活动。持续经营概念假定企业在可预见的未来将继续经营，因此资产按成本而非被迫出售价值来计量。
The accruals concept requires that revenues and expenses are recorded when they are earned or incurred, not necessarily when the cash is received or paid. Consistency means using the same accounting methods from one period to the next, making comparisons meaningful. Prudence tells us to anticipate possible losses but not to recognise profits until they are certain. These concepts form the bedrock of reliable accounting.
权责发生制概念要求，收入和费用在赚取或发生的期间记录，而不一定在收到或支付现金时记录。一贯性意味着在不同期间使用相同的会计方法，从而使比较有意义。谨慎性告诉我们要预计可能的损失，但只有在确定时才确认利润。这些概念构成了可靠会计的基石。
12. Practice Tips and Common Errors | 练习技巧与常见错误
As you work through Year 9 accounting exercises, a structured approach will help you avoid common pitfalls. Always read the transaction carefully and identify the two (or more) accounts affected before writing any journal entry. Write the debit part first, then the credit part, indenting the credit slightly to distinguish them.
在你练习 Year 9 会计题时，采用结构化方法可以帮助你避免常见陷阱。在写任何分录之前，一定要仔细阅读交易并识别受影响的两个（或多个）账户。先写借方，再写贷方，并将贷方稍加缩进以作区分。
One frequent mistake is confusing which side increases an account. Return to the DEAD CLIC rule whenever you feel unsure. Another error is recording the correct accounts but for the wrong amount, so double-check the figures from the transaction. Many students also forget that every transaction must include a date and a brief description, or narration, in journal entries – this makes revision much easier.
一个常见错误是混淆哪一侧增加账户。每当你感到不确定时，就回想 DEAD CLIC 规则。另一个错误是记录正确的账户但金额错误，因此要仔细核对交易中的数字。许多学生也忘记了每笔交易在日记账分录中必须包含日期和简要说明，或称为摘要——这会使复习容易得多。
When the trial balance does not balance, look for the most typical issues: a single-entry mistake where only one side is recorded, transposition errors (e.g., $63 written as $36), and forgetting to include an account balance entirely. Always check if the difference is divisible by 9 – this hints at a transposition error. Recalculating the balances of each ledger account can also uncover arithmetic slips.Published by TutorHao | Year 9 Accounting Revision Series | aleveler.com
