1. Mock Paper Structure and Key Topics | 模拟卷结构与重点
A standard Unit 1 mock paper for WJEC Year 11 Accounting is typically divided into three sections: Section A contains 20 multiple-choice questions worth 1 mark each; Section B consists of short-answer and structured tasks (approx. 30 marks); Section C requires the preparation of an income statement and a statement of financial position from a trial balance and adjustments (approx. 50 marks). The total time allowed is 1 hour 30 minutes. Topics such as the accounting equation, source documents, books of prime entry, ledger accounts, trial balance, accruals and prepayments, depreciation, bad debts and bank reconciliation are all examinable.
一份标准的 WJEC 11 年级会计第一单元模拟卷通常分为三部分：A 部分包含 20 道单选题，每题 1 分；B 部分为简答题和结构化任务（约 30 分）；C 部分要求根据试算平衡表及调整事项编制损益表和财务状况表（约 50 分）。总考试时间为 1 小时 30 分钟。涵盖的知识点包括会计等式、原始凭证、日记簿、分类账、试算平衡表、应计与预付、折旧、坏账和银行对账等。
2. Multiple-Choice Question Analysis: Accounting Equation | 选择题解析：会计等式
Question: Which of the following correctly reflects an element of the accounting equation?
A. Assets + Liabilities = Capital
B. Assets = Liabilities - Capital
C. Capital = Assets - Liabilities
D. Liabilities = Assets + Capital
中文题目：以下哪一项正确反映了会计等式的构成？
A. 资产 + 负债 = 资本
B. 资产 = 负债 - 资本
C. 资本 = 资产 - 负债
D. 负债 = 资产 + 资本
The accounting equation is Assets = Liabilities + Capital. Rearranging this gives Capital = Assets - Liabilities. Option C is therefore correct. The other options misstate the fundamental relationship that every resource of a business is financed either by external claims (liabilities) or by the owner's interest (capital).
会计等式为资产 = 负债 + 资本。变形可得资本 = 资产 - 负债，因此选项 C 正确。其余选项错误地表达了企业资源要么由外部索求权（负债）、要么由业主权益（资本）提供融资的基本关系。
A related multiple-choice item often tests the impact of a transaction on the equation. For example, buying inventory for cash increases one asset and decreases another, leaving the equation unaffected. Purchasing equipment on credit increases both an asset and a liability, again keeping the equation in balance.
相关的选择题常测试交易对等式的影响。例如，用现金购买存货会导致一项资产增加、另一项资产减少，等式保持不变。赊购设备则同时增加资产和负债，等式仍然平衡。
3. Multiple-Choice Question Analysis: Trial Balance Discrepancy | 选择题解析：试算平衡表差异
Question: A trial balance shows total debits of £41,200 and total credits of £40,950. Which of the following errors alone could explain the £250 difference?
A. The sales day book was overcast by £250.
B. A purchase of stationery for £250 was debited to the stationery account but no corresponding credit was recorded.
C. A payment of £250 to a supplier was correctly credited in the bank account but debited to the purchases account.
D. The balance on the motor expenses account was omitted from the trial balance.
中文题目：某试算平衡表的借方总额为 £41,200，贷方总额为 £40,950。以下哪一项错误单独发生即可解释 £250 的差异？
A. 销售日记账多计了 £250。
B. 购 £250 文具时，借记了文具费账户，但没有记录贷方分录。
C. 支付供应商 £250，银行账户正确贷记，但误借记购货账户。
D. 车辆费用账户余额被遗漏，未记入试算平衡表。
The difference is an excess of debits over credits by £250. Overcasting the sales day book by £250 would increase both debtors (debit) and sales (credit) by £250, leaving the trial balance in agreement. Option C records a debit to purchases (expense, debit) and a credit to bank, so both sides are posted, maintaining the balance. Omitting motor expenses, which normally has a debit balance, would cause debits to be understated, making credits higher, which is opposite to the given difference. Option B creates a one-sided entry: a debit of £250 without a credit. Therefore, total debits are overstated by £250, explaining the discrepancy exactly.
差异表现为借方比贷方多 £250。选项 A 多计销售日记账会使应收账款（借方）和销售收入（贷方）同时虚增 £250，试算平衡表依然平衡。选项 C 借记购货（费用，借方）并贷记银行，借贷双方均有记录，总额仍相等。选项 D 遗漏车辆费用（正常为借方余额）会导致借方少计，使贷方相对多出，与题目给出的差异方向相反。选项 B 产生一笔单边分录：借记 £250 却无对应的贷方记录，因此借方总额被高估 £250，完美解释了差异。
4. Short-Answer Question: Journal Entries for Purchases | 简答题：采购日记账分录
Question: On 15 April, Yuki Ltd purchased office furniture for £3,600. A cheque for £800 was paid immediately and the remaining balance is due to OfficePlus Ltd in 30 days. Record the journal entry to account for this transaction. Narrations are required.
中文题目：4 月 15 日，Yuki 公司购入办公家具 £3,600，立即开出 £800 支票付款，余款 30 天内应付 OfficePlus 公司。请编制该交易的日记账分录，须附简要说明。
Answer:
Dr Office furniture £3,600
Cr Bank £800
Cr OfficePlus Ltd (trade payable) £2,800
Being the purchase of office furniture partly paid by cheque and balance on credit.
答案：
借：办公家具 £3,600
贷：银行存款 £800
贷：OfficePlus 公司（应付账款） £2,800
记录购入办公家具，部分以支票支付，余款赊欠。
The furniture account is debited because an asset is increasing. The bank account is credited because the asset of cash is decreasing. The trade payable account is credited to recognise the liability to OfficePlus Ltd. This entry follows the double-entry rule: total debits must equal total credits.
借记家具账户是因为资产在增加。贷记银行存款是因为现金资产减少。贷记应付账款则是确认了对 OfficePlus 公司的负债。该分录遵循复试记账规则：借方总额必须等于贷方总额。
5. Preparing a Trial Balance from Given Balances | 根据给定余额编制试算平衡表
In this task, the following balances have been extracted from the ledger of Zara Traders on 31 December 2024: Capital £30,000; Premises £45,000; Inventory £8,200; Trade payables £4,500; Trade receivables £6,300; Bank (overdraft) £1,150; Sales £68,000; Purchases £39,000; Rent £5,800; Wages £9,200; Motor expenses £3,200; Loan from AB Finance £10,000; Drawings £4,800. Some balances need careful treatment: bank overdraft is a credit balance; drawings is a debit balance. A student incorrectly placed the bank overdraft on the debit side. Identify the error and prepare a corrected trial balance.
在本任务中，以下余额摘录自 Zara Traders 截至 2024 年 12 月 31 日的分类账：资本 £30,000；房产 £45,000；存货 £8,200；应付账款 £4,500；应收账款 £6,300；银行存款（透支）£1,150；销售收入 £68,000；购货 £39,000；租金 £5,800；工资 £9,200；车辆费用 £3,200；AB 金融公司贷款 £10,000；提款 £4,800。一些余额需注意：银行透支为贷方余额；提款为借方余额。某学生误将银行透支置于借方。请识别错误并编制更正后的试算平衡表。
awings) and all credit balances (Capital, Trade payables, Bank overdraft, Sales, Loan). The debit column total equals £45,000 + £8,200 + £6,300 + £39,000 + £5,800 + £9,200 + £3,200 + £4,800 = £121,500. The credit column total is £30,000 + £4,500 + £1,150 + £68,000 + £10,000 = £113,650. These do not agree. The difference of £ ted the inventory balance from the debit side. After including inventory, both sides total £121,500. This demonstrates that trial balance totals must be checked and errors corrected systematically.
正确的试算平衡表应将所有借方余额（房产、存货、应收账款、购货、租金、工资、车辆费用、提款）和所有贷方余额（资本、应付账款、银行透支、销售收入、贷款）分别列出。借方合计为 £45,000 + £8,200 + £6,300 + £39,000 + £5,800 + £9,200 + £3,200 + £4,800 = £121,500；贷方合计为 £30,000 + £4,500 + £1,150 + £68,000 + £10,000 = £113,650。两者不相等。差异 £7,850 有待追查。可能的错误是学生遗漏了存货借方余额。补入存货后，借贷双方合计均为 £121,500。这体现了试算平衡表的合计必须核对并系统性地纠正错误。
6. Adjustments for Accruals and Prepayments | 应计与预付调整
At the end of the financial year, businesses must adjust for expenses incurred but not yet paid (accruals) and payments made in advance (prepayments). For example, electricity charges for December of £240 will be paid in January. The adjustment is: Dr Electricity expense £240, Cr Accruals (liability) £240. This ensures that the income statement records the full year's expense, while the statement of financial position shows the amount owed. Similarly, if rent of £1,000 was paid for three months in advance, £400 relates to the next period. The entry: Dr Prepaid rent (asset) £400, Cr Rent expense £400 reduces the expense in the income statement.
财务年度结束时，企业必须调整已发生但尚未支付的费用（应计费用）和提前支付的款项（预付费用）。例如，12 月的电费 £240 将在 1 月支付。调整分录为：借电费 £240，贷应计费用（负债）£240。这确保损益表记入全年的费用，同时财务状况表列示应付金额。类似地，若提前支付三个月租金 £1,000，其中 £400 属于下一期间，则分录为：借预付租金（资产）£400，贷租金费用 £400，从而减少损益表中的费用。
A mock paper often tests the impact of forgetting these adjustments. Omitting the accrual understates expenses, overstates profit and understates current liabilities. Omitting a prepayment overstates expenses, understates profit and understates current assets. Always identify any carry-over amounts from given information, such as 'rent includes a prepayment of £X' or 'wages outstanding at year end £Y'.
模拟卷常测试遗漏调整的分录所带来的影响。遗漏应计费用会低估费用、高估利润并低估流动负债。遗漏预付费用则会高估费用、低估利润并低估流动资产。务必从给定的信息中识别跨期金额，如“租金中包含预付 £X”或“年末未付工资 £Y”。
7. Income Statement Preparation | 损益表编制
Using the trial balance of Green Ltd, which includes sales £120,000, purchases £65,000, opening inventory £12,500, carriage inwards £800, returns inwards £2,000, discount allowed £1,200, wages £24,000, rent and rates £9,600, insurance £3,400, bad debts £650, and closing inventory £14,200, prepare the income statement for the year ended 31 December 2024.
根据 Green 公司的试算平衡表：销售收入 £120,000，购货 £65,000，期初存货 £12,500，购货运费 £800，销售退回 £2,000，销售折扣 £1,200，工资 £24,000，租金和地税 £9,600，保险费 £3,400，坏账 £650，期末存货 £14,200。编制截至 2024 年 12 月 31 日的年度损益表。
First, calculate net sales: Sales £120,000 - Returns inwards £2,000 = £118,000. Then cost of sales: Opening inventory £12,500 + Purchases £65,000 + Carriage inwards £800 - Closing inventory £14,200 = £64,100. Gross profit = Net sales £118,000 - Cost of sales £64,100 = £53,900. Next, list expenses: Discount allowed £1,200, Wages £24,000, Rent and rates £9,600, Insurance £3,400, Bad debts £650. Total expenses = £38,850. Net profit = Gross profit £53,900 - Expenses £38,850 = £15,050.
首先，计算销售净额：销售收入 £120,000 - 销售退回 £2,000 = £118,000。然后计算销售成本：期初存货 £12,500 + 购货 £65,000 + 购货运费 £800 - 期末存货 £14,200 = £64,100。毛利润 = 销售净额 £118,000 - 销售成本 £64,100 = £53,900。接着列出费用：销售折扣 £1,200，工资 £24,000，租金和地税 £9,600，保险费 £3,400，坏账 £650。费用合计 = £38,850。净利润 = 毛利润 £53,900 - 费用 £38,850 = £15,050。
Ensure you follow the correct format: show gross profit clearly, and classify expenses into selling, administrative and financial if the marks require it. WJEC often expects candidates to present a simple vertical format without extensive classification, but always read the question carefully.
确保遵循正确的格式：清晰列示毛利润，并根据题目分值要求将费用分类为销售费用、管理费用和财务费用。WJEC 通常要求考生采用简单的垂直格式，不需过细的分类，但务必仔细审题。
8. Statement of Financial Position Preparation | 财务状况表（资产负债表）编制
Continuing from the income statement above, the following additional balances are available: freehold premises £80,000, fixtures and fittings £25,000, motor vehicles £18,000, trade receivables £11,300, trade payables £7,550, bank £3,200, 5% bank loan (repayable 2028) £15,000, capital at 1 Jan 2024 £95,000, drawings £9,000. Using net profit £15,050 from the income statement, prepare the statement of financial position as at 31 December 2024.
承接上述损益表，另有以下余额：永久业权房产 £80,000，固定装置和设备 £25,000，机动车辆 £18,000，应收账款 £11,300，应付账款 £7,550，银行存款 £3,200，5%银行借款（2028
