The mock paper is designed to test core knowledge from the first unit of the AQA Accounting course. It includes multiple-choice questions, short calculations, and a trial balance analysis. The total time suggested is 40 minutes. You are allowed to use a calculator but must show your workings for calculation questions.
模拟卷旨在考查AQA会计课程第一单元的核心知识。它包括选择题、简短计算题以及一道试算平衡表分析题。建议总时长为40分钟。允许使用计算器，但计算题必须展示演算过程。
Liabilities + Capital); debit and credit rules for assets, liabilities and capital; simple income statement (revenue minus expenses); and error detection using an unbalanced trial balance.
涵盖的主要知识点有：识别资产、负债和资本；会计等式（资产 = 负债 + 资本）；资产、负债及资本的借贷规则；简易利润表（收入减去费用）；以及借助试算平衡表不平衡来发现错误。
By working through the paper, you will revise the double-entry system and see how every transaction affects at least two accounts. This walkthrough provides detailed explanations so you can apply the same logic to any similar question.
通过完成这份试卷，你将复习复式记账系统，并明白每笔交易如何影响至少两个账户。本次解析提供了详细解释，以便你能将相同的逻辑运用到任何类似题目中。
2. Question 1: Identifying Assets | 第1题：识别资产
Question 1: Which of the following is an asset?
A. Bank loan
B. Trade payables
C. Inventory
D. Capital
第1题：下列哪一项属于资产？
A. 银行贷款
B. 应付账款
C. 存货
D. 资本
The correct answer is C. Inventory is an asset because it is a resource controlled by the business from which future economic benefits are expected. Inventory is goods held for resale. Options A and B are liabilities – amounts the business owes to others. Option D, capital, represents the owner's equity, not an asset.
正确答案是C。存货属于资产，因为它是由企业控制的、预期能带来未来经济利益的资源。存货就是持有待售的商品。选项A和B是负债——即企业欠他人的款项。选项D，资本，代表所有者权益，并不是资产。
This question tests your ability to classify items correctly. Remember the three elements of the accounting equation: assets (what the business owns or controls), liabilities (what the business owes), and capital (the owner's stake). Being able to distinguish these quickly is essential for all later topics.
这道题考查你对项目进行正确分类的能力。牢记会计等式的三要素：资产（企业拥有或控制的资源）、负债（企业欠别人的债务）和资本（所有者的权益）。快速区分这三者对后续所有知识点都至关重要。
A common error is to confuse a bank loan with an asset because the business receives cash. However, the cash is an asset, but the loan itself is a liability. Always think about who has a claim on the resource.
常见的误区是因为企业收到了现金而把银行贷款误认为资产。然而，收到的现金是资产，但贷款本身是负债。始终要考虑谁对该资源享有索取权。
3. Question 2: The Accounting Equation | 第2题：会计等式
Question 2: Complete the accounting equation: Assets = ? + Capital.
Fill in the missing element.
第2题：完成会计等式：资产 = ？+ 资本。
填入缺失的要素。
The missing term is 'Liabilities' ital. This equation must always balance, and it forms the foundation of the balance sheet.
缺失的词是“负债”。因此完整的等式为：资产 = 负债 + 资本。这个等式必须始终保持平衡，并且是资产负债表的基础。
g the business owns (assets) is financed either by borrowing (liabilities) or by the owner' r 8, you must be able to rearrange the equation to find any unknown, e.g. Capital = Assets – Liabilities.
这个等式表明企业拥有的每一件东西（资产）要么是通过借款（负债）融资，要么是通过所有者投资和留存利润（资本）融资。在八年级，你必须能够变形等式以求出任何未知数，例如：资本 = 资产 – 负债。
y to remember the relationship is to think of a simple business: if you buy a computer for £500 using a bank loan of £200 and owner's funds of £300, then Assets (£500) = Liabilities (£200) + Capital (£300). The equation balances.
一个记忆该关系的好方法是设想一家简单的企业：如果用£200银行贷款和£300自有资金购买一台£500的电脑，那么资产(£500) = 负债(£200) + 资本(£300)。等式平衡。
4. Question 3: Double-Entry for Asset Purchase | 第3题：资产购买的复式记账
Question 3: A business buys equipment for £500, paying by bank transfer. Which account is debited and which is credited?
第3题：企业通过银行转账购买设备£500。哪个账户记借方，哪个账户记贷方？
The correct entries are: debit Equipment £500, credit Bank £500. Under double-entry rules, an increase in an asset is debited, while a decrease in an asset is credited. Here, Equipment (an asset) increases, so it is debited; Bank (also an asset) decreases, so it is credited.
正确的分录是：借记设备£500，贷记银行£500。根据复式记账规则，资产增加记借方，资产减少记贷方。本题中，设备（资产）增加了，因此借记；银行（也是资产）减少了，因此贷记。
This transaction does not affect liabilities or capital, so the accounting equation remains in balance. Total assets stay the same: one asset (bank) goes down by £500, and another asset (equipment) goes up by £500. That is a key reason why double-entry always keeps the equation balanced.
这笔交易不影响负债或资本，因此会计等式仍然平衡。总资产保持不变：一项资产（银行）减少了£500，另一项资产（设备）增加了£500。这就是复式记账总能保持等式平衡的关键原因。
Students often mix up which side to use. A simple rule: when you receive value, debit the receiving account; when you give value, credit the giving account. Here, the business 'receives' equipment and 'gives' bank money, so debit equipment and credit bank.
学生常混淆该使用哪一边。一个简单的规则：当收到价值时，借记接收账户；当付出价值时，贷记付出账户。本题中，企业“收到”设备，“付出”银行存款，因此借记设备，贷记银行。
5. Question 4: Trial Balance Review | 第4题：试算平衡表检查
Question 4: The following balances have been extracted from the books at the end of a month. Do they form a balanced trial balance? If not, what is the difference, and suggest one possible reason.
第4题：下列余额是从月末账簿中提取的。它们是否构成平衡的试算平衡表？如果不平衡，差额是多少，并给出一个可能的原因。
| Account | Debit (£) | Credit (£) |
|---|---|---|
| Bank | 1,200 | |
| Capital | 2,000 | |
| Sales | 800 | |
| Purchases | 500 | |
| Rent | 300 |
No, the trial balance is not balanced. Total debits = £1,200 + £500 + £300 = £2,000. Total credits = £2,000 + £800 = £2,800. The credit side exceeds the debit side by £800.
不，试算平衡表不平衡。借方总额 = £1,200 + £500 + £300 = £2,000。贷方总额 = £2,000 + £800 = £2,800。贷方比借方多出£800。
One possible reason is that a debit balance of £800, such as Trade Receivables (money owed by customers), has been omitted from the trial balance. If sales of £800 were made on credit, the corresponding debit entry in Trade Receivables might have been forgotten when listing the balances.
一个可能的原因是，有一笔£800的借方余额，比如应收账款（客户所欠款项），在试算平衡表中被遗漏了。如果£800的销售是赊销，那么在列示余额时可能忘记了相应的应收账款借方分录。
Another explanation could be that the sales account was over-credited or a purchase return was incorrectly posted. In an exam, you simply need to show that you can calculate the difference and offer a reasonable suggestion linked to double-entry errors.
另一种解释可能是销售收入账户被多余地贷记，或者一笔采购退回被错误过账。在考试中，你只需展示你能算出差额，并给出一个与复式记账错误相关的合理建议即可。
6. Question 5: Calculating Net Profit | 第5题：计算净利润
Question 5: A service business has revenue from fees of £2,000. Its expenses are: rent £500, salaries £600, and advertising £200. Calculate the net profit for the period.
第5题：一家服务企业赚取服务费收入£2,000。其费用为：租金£500、工资£600和广告费£200。计算该期间的净利润。
Net profit = Total revenue – Total expenses. Total revenue = £2,000. Total expenses = £500 + £600 + £200 = £1,300. Therefore, net profit = £2,000 – £1,300 = £700.
净利润 = 总收入 – 总费用。总收入 = £2,000。总费用 = £500 + £600 + £200 = £1,300。因此，净利润 = £2,000 – £1,300 = £700。
This simple income statement shows whether the business is profitable. In Year 8, you are not required to calculate gross profit for a service business because there is no cost of sales. Just match the revenue earned with the expenses incurred in the same period.
这张简易利润表显示了企业是否盈利。在八年级，服务企业无需计算毛利，因为没有销售成本。只需将同一期间赚取的收入与发生的费用相配比即可。
A common mistake is to treat rent or salaries as an asset. Remember that expenses reduce capital and are recorded as debit entries in the income statement accounts. When you calculate net profit, you are finding the increase in capital from trading activities.
一个常见错误是把租金或工资当作资产。请记住，费用会减少资本，并在利润表账户中记为借方分录。计算净利润时，你实际上是在求出经营活动带来的资本增加额。
7. Question 6: Credit Sale Entry | 第6题：赊销分录
Question 6: A business sells goods on credit for £800. Which accounts are debited and credited? (Assume only the sale of goods is recorded, not the cost of goods sold.)
第6题：企业赊销商品£800。哪个账户借记，哪个账户贷记？（假设仅记录商品销售收入，不记录销售成本。）
The double-entry is: debit Trade Receivables (a current asset) £800, credit Sales Revenue £800. When a sale is made on credit, the business gains an asset – the right to receive money from the customer – and must record the revenue earned.
复式记账分录为：借记应收账款（流动资产）£800，贷记销售收入£800。当进行赊销时，企业获得了一项资产——向客户收款的权力，同时必须记录赚取的收入。
This follows the rule: asset increase (Trade Receivables) is a debit, and revenue increase (Sales) is a credit. Revenue increases capital, and an increase in capital is recorded on the credit side, which is why sales are credited.
这遵循以下规则：资产增加（应收账款）记借方，收入增加（销售收入）记贷方。收入会增加资本，而资本的增加记录在贷方，这就是销售收入被贷记的原因。
c sales entry. Always check that your entry keeps Assets = Liabilities + Capital balanced.
在后续知识点中，你还会记录销售商品的成本并减少存货，但本单元测试的重点是基础销售分录。始终检查你的分录是否保持了资产 = 负债 + 资本的平衡。
8. Question 7: Finding Capital | 第7题：计算资本
Question 7: At the start of the year, a business has assets of £5,000 and liabilities of £1,500. Calculate the capital as at that date.
第7题：年初，一家企业拥有资产£5,000、负债£1,500。计算该日的资本金额。
Using the accounting equation: Capital = Assets – Liabilities. Capital = £5,000 – £1,500 = £3,500. This represents the owner's residual interest in the business after deducting all liabilities.
运用会计等式：资本 = 资产 – 负债。资本 = £5,000 – £1,500 = £3,500。这代表了扣除所有负债后所有者在企业中的剩余权益。
This question is a straightforward application of the equation. It is often tested together with a requirement to prepare a simple balance sheet. The balance sheet would show non-current assets, current assets, current liabilities, and then capital at the bottom, equalling total net assets.
这道题是等式的直接应用。它常常和编制简易资产负债表的要求一起考查。资产负债表会列示非流动资产、流动资产、流动负债，最后在底部列示资本，等于净资产总额。
Make sure you can rearrange the equation quickly. If given capital and liabilities, find assets by adding them. If given assets and capital, find liabilities by subtraction. Mastering this flexibility is vital for the exam.
确保你能快速变形等式。如果给出资本和负债，通过相加求出资产。如果给出资产和资本，通过相减求出负债。掌握这种灵活性对考试至关重要。
9. Question 8: Detecting Errors | 第8题：发现错误
Question 8: A cash sale of £200 is correctly debited to Cash, but the sales revenue is credited as £20 by mistake. What will happen to the trial balance, and by how much will it be out of balance?
第8题：一笔£200的现金销售正确地借记了现金，但销售收入被错误地贷记为£20。试算平衡表会发生什么？差额是多少？
The trial balance will be out of balance. Total debits will be £200 higher than total credits, because the credit entry is £180 too low. The difference is £180.
试算平衡表将会不平衡。借方总额会比贷方总额多出£200，因为贷方分录少了£180。差额为£180。
This is an error of original entry (incorrect amount in the double entry) that still allows the trial balance to reveal a problem. An unbalanced trial balance indicates that a mistake has been made. The accountant must check all entries to find the transaction where credits do not equal debits.
这是一个原始分录错误（复式记账中金额不正确），它仍能让试算平衡表暴露出问题。试算平衡表不平衡就表明有错误发生。会计人员必须检查所有分录，找到贷方不等于借方的交易。
Errors are a popular exam topic. They test your understanding of the double-entry system. Whenever you see an unbalanced trial balance, calculate the difference and think about whether a single-sided entry was missed or an amount was transposed.
错误是考试的热门话题。它考查你对复式记账系统的理解。只要你看到试算平衡表不平衡，就计算出差额，然后思考是否遗漏了单边分录，或者金额是否被颠倒或错位。
10. Key Exam Tips | 重点应试技巧
Always start by reading the question carefully and underlining the key figures. For calculation questions, show every step of your working – even a simple subtraction can earn method marks if the final answer is wrong.
始终先仔细阅读题目，并在关键数字下划线。对于计算题，展示每一个计算步骤——即使最终答案错了，简单的减法过程也可能得到步骤分。
o not, put the amount of the difference in your answer and mention a possible cause. Never leave the answer blank.
在完成试算平衡表题目之前，先将两栏加总，如果平衡就写上借方 = 贷方。如果不平衡，在答案中写明差额并提及可能的原因。绝不要空着答案。
decrease = debit. Apply these rules with confidence, and you will be able to handle most transactions in Year 8.
把复式记账规则写在一张复习卡片上：资产增加记借方、减少记贷方；负债和资本增加记贷方、减少记借方。自信地运用这些规则，你就能应对八年级的大多数交易。
Finally, manage your time. Allow about one minute per mark. If you get stuck on a question, move on and come back later. A well-attempted paper with some incomplete parts often scores higher than a half-finished one.
最后，合理分配时间。大约每分题用一分钟。如果某道题卡住了，先跳过去，稍后再回来。一份尽力而为但有部分未完成的试卷，通常比一份只做完一半的试卷得分更高。
