1. Question 1: The Accounting Equation | 第1题：会计等式
Question 1 states: A business has assets of £5,000 and liabilities of £2,000. Calculate the owner’s equity.
第1题要求：某企业拥有资产5,000英镑，负债2,000英镑。计算所有者权益。
Answer: The owner’s equity is £3,000. We use the accounting equation Assets = Liabilities + Owner’s Equity, which can be rearranged to Owner’s Equity = Assets – Liabilities. Substituting the numbers gives £5,000 – £2,000 = £3,000.
答案：所有者权益为3,000英镑。我们使用会计等式：资产 = 负债 + 所有者权益，移项后得到所有者权益 = 资产 – 负债。代入数字：5,000 – 2,000 = 3,000英镑。
This equation must always stay in balance. It reflects the dual‑aspect concept: everything the business owns (assets) is funded either by borrowing (liabilities) or by the owner’s contribution and profits (equity). If assets increase without a matching increase in liabilities or equity, the equation would break – which is impossible in double‑entry bookkeeping. This formula is the foundation of everything else in accounting, so learn it well.
这个等式必须始终保持平衡。它反映了复式记账的二元性概念：企业拥有的一切（资产）要么由借款（负债）提供资金，要么由所有者的投入和利润（权益）提供资金。如果资产增加而没有相应的负债或权益增加，等式就会被破坏——这在复式记账中是不可能的。这个公式是会计中其他所有内容的基础，请务必熟练掌握。
2. Question 2: Classifying Accounts | 第2题：账户分类
Question 2 lists several items: cash at bank, a bank loan, inventory, motor vehicles, owner’s capital, and trade payables. You must classify each as an asset, a liability, or owner’s equity.
第2题列出若干项目：银行存款、银行贷款、存货、机动车辆、所有者资本和应付账款。你需要将每一项归类为资产、负债或所有者权益。
- Cash at bank → Asset (a resource controlled by the business)
- Inventory → Asset
- Motor vehicles → Asset
- Bank loan → Liability (an amount owed to the bank)
- Trade payables → Liability (amounts owed to suppliers)
- Owner’s capital → Owner’s equity (the owner’s investment)
- 银行存款 → 资产（由企业控制的资源）
- 存货 → 资产
- 机动车辆 → 资产
- 银行贷款 → 负债（欠银行的款项）
- 应付账款 → 负债（欠供应商的款项）
- 所有者资本 → 所有者权益（所有者的投资）
When you classify accounts, think about what the business controls versus what it owes. Assets are things the business owns or has rights to, such as stock, vehicles, and cash. Liabilities are obligations to pay others in the future. Owner’s equity is the residual interest – what would be left for the owner if all assets were sold and all debts paid. Being able to quickly sort items is a vital skill for reading financial statements and for double‑entry recording.
当你对账户进行分类时，请思考企业控制了什么以及它欠了什么。资产是企业拥有或拥有使用权的物品，例如存货、车辆和现金。负债是未来必须支付给他人的义务。所有者权益是剩余权益——如果所有资产被变卖并偿还所有债务后，留给所有者的部分。快速分类项目的能力是阅读财务报表和进行复式记账的重要技能。
3. Question 3: Debit and Credit Rules | 第3题：借方和贷方规则
Question 3: A business purchases new equipment for £1,200 and pays immediately by cheque. Identify which accounts are debited and credited.
第3题：某企业以支票支付1,200英镑购买新设备。请指出哪些账户应借记和贷记。
Answer: The Equipment account is debited because an asset is increasing. The Bank account is credited because the business’s cash at bank is decreasing. In double‑entry, every transaction affects at least two accounts – one debit and one credit – and the total debit amount always equals the total credit amount.
答案：设备账户应借记，因为资产增加了。银行账户应贷记，因为企业的银行存款减少了。在复式记账中，每笔交易至少影响两个账户——一个借方一个贷方——并且借方总额总是等于贷方总额。
To remember which side to use, apply the DEAD‑CLIC mnemonic: Debit increases Expenses, Assets and Drawings; Credit increases Liabilities, Income and Capital. Purchasing equipment increases an asset (debit), and paying cash reduces another asset, so we credit Bank. If you accidentally reversed them, the accounting equation would go out of balance. Practice this rule until it becomes automatic.
为了记住哪方记增加，可以使用DEAD‑CLIC记忆法：借记增加费用、资产和提款；贷记增加负债、收入和资本。购买设备增加了资产（借记），而支付现金减少了另一项资产，所以贷记银行。如果你不小心颠倒了借贷方向，会计等式就会失衡。请反复练习此规则，直到它变得自然而然。
4. Question 4: Recording a Journal Entry | 第4题：记录日记账分录
Question 4: On 5 June, the business sells goods for £450 cash. Show the journal entry that records this transaction.
第4题：6月5日，企业以现金450英镑出售商品。请写出记录此交易的日记账分录。
The journal entry must capture the date, the accounts affected, and the debit and credit amounts. The sale of goods for cash increases the business’s cash (an asset) and also generates sales revenue. Therefore, we debit Cash £450 and credit Sales £450. A brief narrative is not always required in Year 7, but it is good practice to write something like ‘Sold goods for cash’.
日记账分录必须记录日期、受影响的账户以及借方和贷方金额。以现金出售商品会增加企业的现金（一项资产），同时产生销售收入。因此，我们借记现金450英镑，贷记销售收入450英镑。七年级不一定要求写摘要，但写上类似“以现金出售商品”的叙述是一个好习惯。
Date Account Debit (£) Credit (£)
5 Jun Cash 450
Sales 450
(Sold goods for cash)
日期 账户 借方（英镑） 贷方（英镑）
6月5日 现金 450
销售收入 450
（以现金出售商品）
The journal is called the ‘book of original entry’. All transactions are recorded here first before being posted to the ledger. Always double‑check that debits equal credits; a journal with unequal totals signals a mistake that will later cause the trial balance to fail. This simple sale example shows how revenue increases on the credit side while an asset increases on the debit side.
日记账被称为“原始记录簿”。所有交易首先在这里记录，然后才过账到分类账。务必检查借方和贷方是否相等；总额不平的日记账表明存在错误，后续将导致试算平衡表不平。这个简单的销售例子展示了收入如何在贷方增加，而资产如何在借方增加。
5. Question 5: T‑Account Posting and Balancing | 第5题：T型账户过账与结平
Question 5: The Cash account had an opening balance of £800 on 1 May. During the month, the business received £300 from a customer and paid £120 for stationery. Draw the Cash T‑account and find the closing balance at 31 May.
第5题：5月1日现金账户期初余额为800英镑。当月，企业从客户处收到300英镑，并支付了120英镑办公用品费用。请画出T型现金账户，并计算5月31日的期末余额。
The T‑account has two sides: debit (left) and credit (right). Opening balance on debit side: £800. The receipt of £300 increases cash, so debit Cash £300. The payment of £120 decreases cash, so credit Cash £120. To balance the account, total the debit side (£800 + £300 = £1,100) and the credit side (£120). The difference is £980, which becomes the closing balance carried down to the next period.
T型账户有两方：借方（左）和贷方（右）。借方期初余额：800英镑。收到300英镑增加了现金，因此借记现金300英镑。支付120英镑减少了现金，因此贷记现金120英镑。要结平账户，将借方合计（800 + 300 = 1,100英镑）和贷方合计（120英镑）相加。差额为980英镑，这成为结转至下期的期末余额。
Cash Account
Dr Cr
1 May Bal b/d 800 15 May Stationery 120
10 May Customer 300 31 May Bal c/d 980
1,100 1,100
1 Jun Bal b/d 980
现金账户
借方 贷方
5月1日 期初余额 800 5月15日 办公用品 120
5月10日 客户 300 5月31日 期末余额 980
1,100 1,100
6月1日 期初余额 980
Posting to T‑accounts helps you see how transactions change individual account balances. Always bring down the balance on the larger side so that the two totals match. The phrase ‘balance carried down’ (c/d) is used on the last day of the period, and ‘balance brought down’ (b/d) on the first day of the next period. This technique prepares you for extracting a trial balance.
过账到T型账户帮助你了解交易如何改变各个账户的余额。总是在金额较大的一边结转余额，以使两边的合计相等。期末最后一天使用“结转下期余额”（c/d），下期第一天使用“上期结转余额”（b/d）。这种技巧为编制试算平衡表做好准备。
6. Question 6: Trial Balance Preparation | 第6题：试算平衡表编制
Question 6: The following balances have been extracted from the ledgers: Purchases £2,400 Dr, Sales £3,100 Cr, Cash £1,500 Dr, Capital £2,000 Cr, Equipment £1,800 Dr, and Trade Payables £800 Cr. Prepare the trial balance and check whether it balances. If not, identify the difference and suggest what could have caused it.
第6题：以下余额摘自分类账：采购2,400英镑（借方），销售收入3,100英镑（贷方），现金1,500英镑（借方），资本2,000英镑（贷方），设备1,800英镑（借方），应付账款800英镑（贷方）。编制试算平衡表并检查其是否平衡。如果不平，找出差额并推测可能出现的原因。
First, list all accounts with their debit or credit balances in a table. Total the debit column and the credit column.
首先，将所有账户及其借方或贷方余额列入表格。分别合计借方栏和贷方栏。
| Account | Debit (£) | Credit (£) |
|---|---|---|
| Purchases | 2,400 | |
| Cash | 1,500 | |
| Equipment | 1,800 | |
| Sales | 3,100 | |
| Capital | 2,000 | |
| Trade Payables | 800 | |
| Totals | 5,700 | 5,900 |
| 账户 | 借方（英镑） | 贷方（英镑） |
|---|---|---|
| 采购 | 2,400 | |
| 现金 | 1,500 | |
| 设备 | 1,800 | |
| 销售收入 | 3,100 | |
| 资本 | 2,000 | |
| 应付账款 | 800 | |
| 合计 | 5,700 | 5,900 |
The totals reveal that credits exceed debits by £200 (5,900 – 5,700). The trial balance does not balance. A difference of £200 could be caused by a transaction being recorded on only one side, by an error in addition when balancing an account, or by a credit balance of £200 being mistakenly omitted. A common possibility is that a £200 sales return or a bank interest received was forgotten. The accountant must go back through the journals to find the missing entry.
合计结果显示贷方比借方多出200英镑（5,900 – 5,700）。试算平衡表不平。200英镑的差额可能由以下原因导致：一笔交易只记录了一方，账户结平时加法错误，或者一笔200英镑的贷方余额被错误遗漏。常见的可能性是忘记了一笔200英镑的销售退回或一笔银行利息收入。会计人员必须回头检查日记账，找到缺失的分录。
7. Question 7: Calculating Profit | 第7题：计算利润
Question 7: During its first month, a business earned sales revenue of £1,800 and incurred expenses totalling £1,150. What is the profit for the period? Show your working.
第7题：在第一个月，某企业获得销售收入1,800英镑，发生费用总计1,150英镑。本期利润是多少？请展示计算过程。
Profit = Total Revenue – Total Expenses. Thus, Profit = £1,800 – £1,150 = £650. The business made a profit of £650. Profit is added to the owner’s capital in the statement of financial position because it increases the owner’s equity. If expenses had been greater than revenue, the business would have made a loss, which reduces equity.
利润 = 总收入 – 总费用。因此，利润 = 1,800 – 1,150 = 650英镑。该企业实现了650英镑的利润。利润会加记到财务状况表中的所有者资本中，因为它增加了所有者权益。如果费用大于收入，企业就会发生亏损，从而减少权益。
It is essential to match all the revenue earned in a period with all the expenses incurred in that same period – this is called the accruals concept. Even if cash has not yet been received or paid, you record the revenue and expenses when they are earned or incurred. For Year 7, you usually work with simple cash‑based numbers, but knowing the idea helps you understand why profit is different from the cash balance.
将某一时期赚取的所有收入与同一时期发生的所有费用进行匹配至关重要——这被称为应计概念。即使现金尚未收到或支付，你也应在收入赚取和费用发生时予以记录。对于七年级，你通常使用简单的现金制数字，但了解这一理念有助于你理解利润为何与现金余额不同。
8. Question 8: Why the Accounting Equation Must Balance | 第8题：为什么会计等式必须平衡
Question 8: Explain in your own words why the accounting equation (Assets = Liabilities + Owner’s Equity) must always balance, using an example.
第8题：用你自己的话解释为什么会计等式（资产 = 负债 + 所有者权益）必须始终保持平衡，并举例说明。
The equation must balance because every economic transaction has a dual effect on the business. There is always a source of funds and a use of funds. If the owner invests £2,000 cash into the business, assets (cash) increase by £2,000, and owner’s equity (capital) increases by £2,000. Both sides rise by the same amount, so the equation remains equal. If the business later buys a laptop for £500 using a bank loan, assets (equipment) go up by £500, and liabilities (loan) also increase by £500 – again preserving the balance.
等式必须平衡，因为每笔经济交易对企业都有双重影响。总是存在资金来源和资金运用。如果所有者向企业投入2,000英镑现金，资产（现金）增加2,000英镑，同时所有者权益（资本）增加2,000英镑。两边增加相同的金额，因此等式保持平等。如果企业后来用银行贷款购买了一台价值500英镑的笔记本电脑，资产（设备）增加500英镑，负债（贷款）也增加500英镑——再次保持了平衡。
If a transaction were recorded on only one side, the equation would break. For instance, recording the purchase of inventory by debiting inventory but forgetting to credit cash or payables would make assets appear larger than the source of funds. That would violate the fundamental rule of double‑entry. The trial balance and the accounting equation are two ways of checking that the books are arithmetically correct. Always remember: for every debit, there must be an equal and corresponding credit.
如果交易只记录了一方，等式就会被破坏。例如，记录存货采购时借记存货但忘记贷记现金或应付账款，就会使资产看起来大于资金来源。这将违反复式记账的基本规则。试算平衡表和会计等式是检查账簿算术正确性的两种方法。务必记住：每一笔借记，都有一笔同等且对应的贷记。
