1. What is Accounting? | 什么是会计？
Accounting is the systematic process of recording, classifying, summarising, and interpreting financial transactions. Its main purpose is to provide useful information to help people make informed business decisions. Accountants track money coming in and going out, and they prepare reports that show how well a business is performing.
会计是对财务交易进行系统记录、分类、汇总和解读的过程。其主要目的是提供有用的信息，帮助人们做出明智的商业决策。会计人员追踪资金的进出，并编制报告以显示企业的经营状况。
There are two main groups of accounting information users: internal users, such as managers and owners, and external users, such as investors, banks, and government authorities. Internal users need detailed reports to run the business day-to-day, while external users rely on summary reports to decide whether to lend money or invest.
会计信息的使用者主要分为两组：内部使用者，例如经理和业主；以及外部使用者，例如投资者、银行和政府机构。内部使用者需要详细报告来营运企业，而外部使用者则依赖汇总报告来决定是否贷款或投资。
In Year 7, you will learn how financial data is organised into a series of accounting records called books of original entry, ledgers, and finally financial statements. All of this is built on one fundamental idea: the accounting equation.
在七年级，你将学习如何将财务数据组织成一系列会计记录，即原始分录簿、分类账，最后是财务报表。这一切都建立在一个基本思想之上：会计等式。
2. The Accounting Equation | 会计等式
The accounting equation is the foundation of the entire accounting system. It states that a business’s resources (assets) are always equal to the claims against those resources (liabilities plus owner’s equity). This relationship must stay in balance at all times.
会计等式是整个会计体系的基础。它表明企业的资源（资产）总是等于对这些资源的求偿权（负债加上所有者权益）。这一关系必须在任何时候都保持平衡。
Assets = Liabilities + Owner’s Equity
资产 = 负债 + 所有者权益
For example, if a business has cash of $10 000, inventory worth $5 000, and a bank loan of $4 000, the owner’s equity must be $11 000 to keep the equation balanced: $15 000 = $4 000 + $11 000. Every transaction affects at least two items in this equation, but the total of both sides always remains equal.
例如，若一家企业拥有现金 10 000 美元、价值 5 000 美元的存货以及一笔 4 000 美元的银行贷款，那么所有者权益必须为 11 000 美元才能使等式保持平衡：$15 000 = $4 000 + $11 000。每笔交易至少影响该等式中的两个项目，但两边总和始终保持相等。
Understanding this equation helps you see why every debit entry needs a corresponding credit entry. It also explains how profit increases owner’s equity and how drawings by the owner reduce it.
理解这一等式有助于你明白为什么每一笔借方分录都需要一笔对应的贷方分录。它还能解释利润为何会增加所有者权益，而业主提款为何会减少所有者权益。
3. Assets | 资产
Assets are resources controlled by a business as a result of past events and from which future economic benefits are expected to flow to the business. In simple terms, assets are what the business owns or has the right to use, such as cash, equipment, and premises.
资产是企业因过去事项而控制的资源，预期将为企业带来未来经济利益。简而言之，资产是企业拥有或有权使用的东西，例如现金、设备和房产。
Assets are divided into two main categories. Current assets are those expected to be turned into cash or used up within one year, such as cash at bank, trade receivables (debtors), and inventory. Non-current assets, also called fixed assets, are held for long-term use, such as machinery, vehicles, and buildings.
资产分为两大类。流动资产是指预期在一年内变现或耗用的资产，如银行存款、应收账款（债务人）和存货。非流动资产，也称固定资产，是供长期使用的资产，如机器、车辆和建筑物。
When recording assets, we always use the original cost, not the current market value. This is known as the historical cost convention. For instance, a building bought for $200 000 five years ago is still recorded at $200 000 in the books, even if its market value has increased.
记录资产时，我们始终使用原始成本，而不是当前市场价值。这被称为历史成本惯例。例如，一栋五年前以 200 000 美元购买的大楼，即使其市场价值已上涨，账面仍记为 200 000 美元。
4. Liabilities | 负债
Liabilities are present obligations of a business arising from past events, the settlement of which is expected to result in an outflow of resources. In other words, liabilities are what the business owes to others, such as loans and unpaid bills.
负债是企业由于过去事项而产生的现时义务，预期会导致资源流出。换句话说，负债是企业欠别人的款项，例如贷款和未付账单。
Similar to assets, liabilities are split into current and non-current. Current liabilities are due to be paid within one year, for example trade payables (creditors), bank overdrafts, and short-term loans. Non-current liabilities are long-term debts that do not need to be repaid within the next year, like a five-year bank loan.
与资产类似，负债也分为流动负债和非流动负债。流动负债是在一年内需要偿还的债务，例如应付账款（债权人）、银行透支和短期借款。非流动负债是指不需要在一年内偿还的长期债务，如五年期银行贷款。
Liabilities appear on the right-hand side of the accounting equation. When a business borrows money, liabilities increase; when it repays a loan, liabilities decrease. Keeping track of liabilities is crucial because a business must have enough assets to settle what it owes.
负债出现在会计等式的右侧。当企业借款时，负债增加；当企业偿还贷款时，负债减少。追踪负债至关重要，因为企业必须有足够的资产来清偿其所欠的债务。
5. Owner’s Equity | 所有者权益
Owner’s equity represents the owner’s financial interest in the business. It is the residual amount after deducting all liabilities from total assets. If the business were to sell all its assets and pay off all debts, the remaining amount would belong to the owner. That is why equity is sometimes called ‘net assets’.
所有者权益代表业主在企业的财务利益。它是从总资产中扣除所有负债后的剩余金额。如果企业变卖所有资产并清偿所有债务，剩下的金额就归业主所有。因此，权益有时也被称为‘净资产’。
There are four main elements that change owner’s equity. Capital introduced by the owner increases equity. Drawings, when the owner takes out cash or goods for personal use, decrease equity. Profit earned from business activities increases equity, while a loss reduces it. These movements are summed up in the equity section of the statement of financial position.
有四个主要因素会引起所有者权益的变化。业主投入的资本会增加权益。提款，即业主提取现金或商品供个人使用，会减少权益。经营活动产生的利润增加权益，而亏损则减少权益。这些变动汇总反映在财务状况表的权益部分。
A simple way to remember the link is the expanded equation: closing capital = opening capital + capital introduced + profit – drawings. This formula helps you see how the owner’s claim changes over an accounting period.
一个记住这一关联的简便方法是扩展公式：期末资本 = 期初资本 + 投入资本 + 利润 – 提款。这一公式能帮助你了解在一个会计期间内业主的求偿权如何变化。
6. Double-Entry Bookkeeping and the Rules of Debit and Credit | 复式记账法与借贷规则
Double-entry bookkeeping means that every financial transaction affects at least two accounts. For each transaction, the total amount debited must equal the total amount credited. This system keeps the accounting equation in balance and makes it easier to detect errors.
复式记账法意味着每一笔财务交易至少会影响两个账户。对于每一笔交易，借方总金额必须等于贷方总金额。这一制度使会计等式保持平衡，并更容易发现错误。
To apply double entry correctly, you must learn the rules of debit and credit. Accounts are classified as assets, liabilities, equity, income, or expenses. The basic rules are:
要正确应用复式记账，你必须学习借方和贷方规则。账户分为资产、负债、权益、收入和费用。基本规则如下：
Debit entries increase assets and expenses, and decrease liabilities, equity, and income. Credit entries do the opposite: they increase liabilities, equity, and income, and decrease assets and expenses.
借方分录增加资产和费用，减少负债、权益和收入。贷方分录则相反：它们增加负债、权益和收入，减少资产和费用。
For example, when the owner invests cash of $5 000 into the business, the Cash account (an asset) is debited, and the Capital account (equity) is credited. If the business later pays $200 for stationery, the Stationery Expense account is debited, and Cash is credited. This dual effect is at the heart of all accounting records.
例如，当业主向企业投入现金 5 000 美元时，现金账户（资产）记在借方，资本账户（权益）记在贷方。如果企业后来支付 200 美元购买文具，文具费用账户记在借方，现金记在贷方。这种双重影响是全部会计记录的核心。
7. The General Journal | 普通日记账
The general journal, often simply called the journal entry, is the first place where transactions are recorded in chronological order. Each journal entry shows the date, the accounts to be debited and credited, a brief narrative, and the amounts. This record is called the book of original entry.
普通日记账，通常简称为日记账分录，是按时间顺序首次记录交易的地方。每一笔日记账分录都列明日期、应借记和应贷记的账户、简要说明以及金额。这种记录被称为原始分录簿。
A typical journal layout includes: Date, Details (account names), Debit column, Credit column, and Narration. The account to be debited is written first, flush left; the account to be credited is written next, indented slightly. The narration explains the transaction briefly.
典型的日记账格式包括：日期、摘要（账户名称）、借方栏、贷方栏和说明。应借记的账户先写，靠左对齐；应贷记的账户接着写，略微缩进。说明部分简要解释该笔交易。
For instance, on 1 March a business buys a computer for $1 200 in cash. The journal entry would be:
例如，3 月 1 日，一家企业用现金购买一台计算机，价值 1 200 美元。日记账分录为：
Debit: Office Equipment $1 200
Credit: Cash $1 200
Narration: Purchased computer for office use.
借方：办公设备 $1 200
贷方：现金 $1 200
说明：购置办公室用计算机。
Learning to prepare proper journal entries is a key skill because all later records, such as ledger accounts, depend on them.
学会编制规范的日记账分录是一项关键技能，因为所有后续记录，如分类账户，都依赖于它们。
8. Ledger Accounts | 分类账
After transactions are recorded in the journal, the next step is to post them to ledger accounts. A ledger is a collection of T-accounts, each representing a different item such as Cash, Sales, or Rent Expense. The left side of a T-account is the debit side, and the right side is the credit side.
交易在日记账中记录后，下一步是将其过账到分类账户。分类账是 T 型账户的集合，每个账户代表不同的项目，如现金、销售收入或租金费用。T 型账户的左边是借方，右边是贷方。
When posting, you transfer the debit and credit amounts from the journal entry to the respective T-accounts. The date, description, and amount are recorded on the correct side. At the end of a period, each T-account is balanced: the difference between total debits and total credits is called the balance carried down, which is then brought down to the opposite side for the next period.
过账时，你将日记账分录中的借方和贷方金额转移到相应的 T 型账户中。日期、说明和金额被记录在正确的一侧。在期末，每个 T 型账户进行结平：借方总额与贷方总额之间的差额称为结转余额，然后将其移至相反一侧作为下期期初余额。
Example: if the Cash account receives a debit of $5 000 and a later credit of $200, the account will show a closing debit balance of $4 800. This balance appears as an asset in the trial balance and the statement of financial position.
举例：如果现金账户有一笔 5 000 美元的借方记录和后来一笔 200 美元的贷方记录，那么该账户将显示一个 4 800 美元的借方期末余额。该余额将作为一项资产出现在试算平衡表和财务状况表中。
9. The Trial Balance | 试算平衡表
A trial balance is a list of all ledger account balances at a particular date, divided into debit and credit columns. Its main purpose is to check the arithmetic accuracy of the double-entry records. If total debits equal total credits, the books are said to ‘balance’.
试算平衡表是列示某一特定日期所有分类账户余额的清单，分为借方栏和贷方栏。其主要目的是检查复式记账记录的算术准确性。如果借方总额等于贷方总额，账簿就被认为是‘平衡的’。
Even when the trial balance balances, errors may still exist. For example, a transaction might be completely omitted, entered twice, or posted to the wrong account. These errors do not affect the equality of debits and credits but will distort financial statements. A trial balance is therefore a useful but not an absolute proof of accuracy.
即使试算平衡表是平衡的，仍可能存在错误。例如，一笔交易可能被完全遗漏、重复记录或过账到错误的账户。这些错误不会影响借方和贷方的相等关系，但会歪曲财务报表。因此，试算平衡表是有用的，但并非准确性的绝对证明。
When the trial balance does not balance, you need to investigate differences. Common causes include arithmetic mistakes in balancing accounts, posting only one side of a journal entry, or transposition errors (e.g., writing 54 as 45). Finding these errors is an important Year 7 accounting skill.
当试算平衡表不平衡时，你需要调查差异。常见原因包括账户结平时计算错误、仅过账了日记账分录的一侧，或者数字移位错误（如将 54 写成 45）。找出这些错误是七年级会计的一项重要技能。
10. The Income Statement | 利润表
The income statement, also called the profit and loss account, summarises a business’s income and expenses over a period of time, usually a year. It shows whether the business has made a profit (if income exceeds expenses) or a loss (if expenses exceed income).
利润表，又称损益表，汇总了企业在一段时期（通常为一年）内的收入和费用。它显示企业是实现了利润（收入大于费用）还是发生了亏损（费用大于收入）。
A simple income statement for a service business starts with revenue, for example fees earned. Then various expenses are listed and subtracted: wages, rent, stationery, and electricity, among others. The result is the net profit or net loss for the period.
服务型企业的简单利润表以收入开头，例如赚取的服务费。然后列出各项费用并加以扣减：工资、租金、文具和电费等。所得结果就是当期的净利润或净亏损。
Net Profit = Total Revenue – Total Expenses
净利润 = 总收入 – 总费用
In Year 7, you will also learn that expenses are matched to the period in which they are used, not necessarily when they are paid. This is the matching principle. For example, rent for December paid in November is still an expense for December.
在七年级，你还会学到费用应与其发生的期间相配比，而不一定是实际支付的时间。这就是配比原则。例如，11 月支付 12 月的租金，仍属于 12 月的费用。
11. The Statement of Financial Position | 财务状况表
The statement of financial position, traditionally called the balance sheet, shows the assets, liabilities, and owner’s equity of a business at a specific point in time, usually the end of the financial year. It is a snapshot of the accounting equation in action.
财务状况表，传统上称为资产负债表，列示企业在某一特定时点（通常是财务年末）的资产、负债和所有者权益。它是会计等式的即时快照。
This statement is set out in a clear format. Non-current assets are listed first, such as equipment and vehicles, followed by current assets like inventory and cash. Then liabilities are shown: current liabilities such as trade payables, and non-current liabilities such as long-term loans. Finally, the owner’s equity section shows the closing capital, calculated as opening capital plus profit less drawings.
该报表以清晰的格式列报。首先列出非流动资产，如设备和车辆，然后是流动资产，如存货和现金。接着列示负债：流动负债，如应付账款，以及非流动负债，如长期借款。最后，所有者权益部分显示期末资本，计算方式为期初资本加利润减提款。
Because the accounting equation must hold, total assets will always equal total liabilities plus equity. If they do not, it signals an error in preparing the statement.
由于会计等式必须成立，总资产将始终等于总负债加上权益。如果两者不相等，就表示编制报表时出现了错误。
12. Key Terminology and Common Mistakes | 核心术语与常见错误
Building a strong vocabulary is essential in accounting. Here are some crucial terms: Debtor (trade receivable) is a customer who owes the business money. Creditor (trade payable) is a supplier the business owes. Drawings are withdrawals by the owner. Capital is the owner’s investment. Revenue is income earned from selling goods or services. Expenses are costs incurred in running the business.
积累丰富的词汇在会计中至关重要。以下是一些关键术语：债务人（应收账款）是欠企业款项的客户。债权人（应付账款）是企业欠其款项的供应商。提款是业主提取的款项。资本是业主的投资。收入是销售商品或服务所得。费用是经营企业所产生的成本。
Common Year 7 mistakes include confusing debtors and creditors, applying the wrong debit or credit rule to expenses, and forgetting that drawings reduce equity, not expenses. Many students also muddle the income statement (showing performance over a period) with the statement of financial position (showing position at a date).
七年级常见错误包括混淆债务人和债权人、对费用应用错误的借贷规则，以及忘记提款是减少权益而不是增加费用。许多学生也会将利润表（显示某个期间的业绩）与财务状况表（显示某个日期的财务状况）相混淆。
Another trap is treating the trial balance as a final statement. It is only an internal check. Always remember: the trial balance helps find arithmetic mistakes, but it cannot prove that every transaction has been recorded correctly. Regular practice with journal entries, ledgers, and financial statements will build your confidence and accuracy.
另一个误区是将试算平衡表当作最终报表。它只是一项内部检查。务必记住：试算平衡表有助于发现算术错误，但不能证明每一笔交易都已正确记录。经常练习日记账分录、分类账和财务报表，将帮助你建立信心并提高准确性。
