Mastering CIE IGCSE Physics (0625) is about more than just knowing the facts – it requires a clear understanding of how marks are awarded and what examiners expect in your answers. This guide covers essential exam techniques and the marking criteria you need to turn your physics knowledge into top marks.
想要在 CIE IGCSE 物理 (0625) 中取得高分，仅靠记住知识点是远远不够的——你还需要清楚了解评分方式，以及阅卷官在你的答案中寻找什么。这份指南将介绍关键的答题技巧和评分标准，帮助你把自己的物理知识转化为高分。
1. Understanding the Exam Papers | 了解试卷结构
The CIE IGCSE Physics examination consists of three papers: Paper 2 (Multiple Choice), Paper 4 (Theory, Extended), and either Paper 5 (Practical Test) or Paper 6 (Alternative to Practical). Knowing the format, duration and mark allocation for each paper is the first step in your preparation.
CIE IGCSE 物理考试由三份试卷组成：试卷二（选择题）、试卷四（理论，拓展）以及试卷五（实验操作）或试卷六（实验笔试替代）。了解每份试卷的题型、时长和分值分配是你备考的第一步。
Paper 2 lasts 45 minutes and contains 40 multiple‑choice questions, each worth one mark. There is no negative marking, so attempt every question.
试卷二时长 45 分钟，包含 40 道单选题，每题 1 分。不倒扣分，因此每题都要尝试作答。
Paper 4 is a 1 hour 15 minute written paper with short‑answer and structured questions, worth 80 marks. Around 20% of the marks are allocated to questions testing knowledge with understanding, 40% to handling information and problem solving, and 40% to experimental skills (tested within this paper if you are not sitting Paper 5).
试卷四为 1 小时 15 分钟的笔试试卷，包含简答题和结构化问题，共 80 分。大约 20% 的分数考查对知识的理解和掌握，40% 考查对信息的处理和解决问题的能力，另外 40% 考查实验技能（如果不参加试卷五，这部分内容也在此试卷中考查）。
Paper 5 or 6 focuses on practical skills. Paper 5 is a hands‑on test; Paper 6 is a written paper about experimental design and data analysis. Both are worth 40 marks and last 1 hour 15 minutes.
试卷五或六侧重实验技能。试卷五为动手操作考试；试卷六为笔试，考查实验设计和数据分析。两卷均为 40 分，时长 1 小时 15 分钟。
Review the latest syllabus document from the CIE website to see the exact weightings and topics. Having a clear exam map will help you allocate revision time wisely.
请查阅 CIE 官网上的最新大纲文件，明确各部分所占权重和具体课题。清晰的考试地图将帮助你合理分配复习时间。
2. Command Words and What They Mean | 指令词及其含义
Command words in questions tell you exactly what the examiner wants. Misinterpreting them can cost you marks even if you know the physics.
题目中的指令词明确告诉了你阅卷官希望看到什么样的回答。即使你掌握了物理知识，误解指令词也可能导致失分。
| Command Word | What It Means | 中文含义 |
|---|---|---|
| State | Give a concise answer, no explanation needed. | 给出简洁答案，无需解释。 |
| Describe | Say what happens or what you observe, step by step. | 说出发生了什么或观察到什么，逐步表述。 |
| Explain | Give reasons or use scientific principles to say why something happens. | 给出原因或运用科学原理说明为什么发生。 |
| Calculate | Work out a numerical answer, showing your working. | 计算出数值答案，并展示步骤。 |
| Suggest | Apply your knowledge to a new situation; there may be more than one correct answer. | 将知识应用于新情境；可能有多个正确答案。 |
| Compare | Give similarities and differences. | 列出相似点和不同点。 |
'Explain' questions often carry the most marks. Use linking words like 'because', 'so', 'therefore' to build logical chains.
“解释”类题目通常占分较高。使用“因为”、“因此”、“所以”等词语来构建逻辑链条。
Always read the command word twice before you start writing. Underline it in the question paper to keep focused.
落笔前，务必将指令词读两遍，并在试卷上将其划出，以便保持注意力。
3. Using Scientific Terminology Accurately | 准确使用科学术语
Examiners expect precise language. Saying 'heat rises' instead of 'warm air expands and becomes less dense, so it rises' loses credit.
阅卷官期待精确的语言。如果说“热量上升”而非“暖空气膨胀，密度减小，因而上升”，就会丢分。
Key terms such as 'energy transferred', 'potential difference', 'current', 'moment of a force' and 'centre of mass' must be used correctly. For example, 'voltage' is acceptable, but 'potential difference' is the preferred term in most exam answers.
“能量转移”、“电势差”、“电流”、“力的力矩”和“质心”等关键术语必须正确使用。例如，“voltage”可以使用，但在大多数考试答案中，“potential difference”是更受推荐的术语。
When describing motion, use 'acceleration' rather than 'speeding up' unless the question specifically asks for simple description. Likewise, in wave topics, differentiate between 'longitudinal' and 'transverse'.
在描述运动时，除非题目明确要求简单描述，否则应使用“加速度”而不是“加速”。同样，在波动章节中，要区分“纵波”和“横波”。
Keep a glossary of terms while you revise. Practice writing full‑sentence definitions, e.g. 'Work is done when a force moves an object in the direction of the force.'
复习时，保持一份术语词汇表。练习用完整句子书写定义，例如“当力使物体沿力的方向移动时，就做了功。”
4. Showing Working and Steps | 展示解题步骤
In Paper 4 calculation questions, marks are awarded for method (M marks) and for the final answer (A marks). Even if your final answer is wrong, you can still earn most of the marks if your working is clear.
在试卷四的计算题中，分数会分配在解题方法（M 分）和最终答案（A 分）上。即使最终答案错误，只要解题步骤清晰，你依然可以获得大部分分数。
Always write down the formula you are using, substitute the numbers with correct units, and then calculate.
始终先写下所用公式，代入正确单位的数值，然后再进行计算。
v = u + at → v = 0 + (2.0 m/s²) × (5.0 s) → v = 10 m/s
If a question has multiple parts, label your steps (a), (b) clearly. Use the space provided; do not squeeze working into margins.
如果问题包含多个部分，请清晰标注 (a)、(b) 等步骤。使用提供的答题空间，不要把步骤挤在页边距里。
For graph questions, mark data points with small crosses, draw a best‑fit line, and when reading values, show on the graph how you obtained them.
对于图表题，用小的十字标记数据点，画出最佳拟合线，读取数值时，在图表上标明你是如何得到这些值的。
5. Handling Calculations and Units | 处理计算与单位
Correct units are just as important as the numerical value. A missing or wrong unit can cost a mark, especially in final answers.
正确的单位与数值同样重要。遗漏或错误的单位都可能导致失分，特别是在最终答案中。
Learn the standard SI units: metre (m), kilogram (kg), second (s), ampere (A), kelvin (K), mole (mol). Derived units such as newton (N), joule (J), watt (W) and pascal (Pa) must be applied correctly.
学习标准国际单位：米 (m)、千克 (kg)、秒 (s)、安培 (A)、开尔文 (K)、摩尔 (mol)。导出单位如牛顿 (N)、焦耳 (J)、瓦特 (W) 和帕斯卡 (Pa) 必须正确使用。
cm² = (0.01 m)² = 1 × 10⁻⁴ m². This is a common pitfall in pressure and density questions.
进行单位换算时，例如从 cm² 换算到 m²，记住：1 cm² = (0.01 m)² = 1 × 10⁻⁴ m²。这是压强和密度问题中常见的陷阱。
numbers, e.g. the charge on an electron = -1.6 × 10⁻¹⁹ C. The exam expects this notation.
对于非常大或非常小的数字，使用标准形式，例如一个电子的电荷 = -1.6 × 10⁻¹⁹ C。考试中希望使用这种记法。
When tackling multi‑step calculations, keep intermediate values in your calculator and round only at the final answer. Give your answer to a sensible number of significant figures (usually 2 or 3, matching the data given).
处理多步计算时，将中间数值保留在计算器中，只对最终答案进行四舍五入。答案的有效数字要合理（通常是 2 到 3 位，与题目所给数据一致）。
6. Drawing and Interpreting Graphs | 画图与解读图表
Graph skills are tested in both Paper 4 and the practical papers. You must be able to choose scales, plot points, draw lines and calculate gradients.
图形技能在试卷四和实验试卷中都会考查。你必须会选择坐标比例、描点、画线并计算斜率。
Choose a scale that uses more than half the graph grid in each direction. Avoid awkward scales such as 3, 7, or 13 units per large square – stick to 1, 2, 5 or multiples of 10.
选择的比例尺应该使每条坐标轴占据图形格的一半以上。避免使用 3、7 或 13 个单位每大格这种别扭的比例——坚持使用 1、2、5 或 10 的倍数。
Plot points accurately with a sharp pencil. When drawing a best‑fit straight line, ensure the line passes through as many points as possible with roughly equal numbers of points on either side.
用削尖的铅笔准确描点。画最佳拟合直线时，确保直线尽可能穿过更多数据点，且直线两侧的点数大致相等。
To find the gradient, draw a large triangle on the graph and use:
gradient = Δy / Δx
Label the coordinates you use, and show the subtraction. Never rely on the coordinates of plotted data points alone – use points on your line.
标注你所使用的坐标，并写出减法过程。切勿仅依赖所描数据点的坐标——应使用直线上读取的点。
Interpretation: if the graph is a straight line through the origin, the two quantities are directly proportional. If the line is straight but does not pass through the origin, they have a linear relationship but are not proportional.
解读：如果图线是一条通过原点的直线，则两个量成正比。如果直线不通过原点，则它们具有线性关系，但不成正比。
7. Tackling Practical‑Based Questions | 应对实验题
ts. Use the standard structure: Apparatus → Method → Observations → Analysis → Conclusion.
不论你参加试卷五还是试卷六，都需要描述实验、找出误差来源并提出改进方法。使用标准结构：器材 → 方法 → 观察 → 分析 → 结论。
When asked to plan an experiment, list the apparatus (e.g. metre rule, stopwatch, ammeter, variable resistor). Explain how you will change the independent variable, measure the dependent variable, and control other variables.
当被要求设计实验时，列出所用器材（如米尺、秒表、电流表、变阻器）。解释你将如何改变自变量、测量因变量以及控制其他变量。
For example, to investigate how the length of a wire affects its resistance: ' cord the current I and the p.d. V. Calculate resistance R = V / I. Repeat for different lengths, keeping the wire material and temperature constant.'
例如，探究导线长度对其电阻的影响：“将导线、串联的电流表和并联的电压表接入电路。用米尺测量导线长度。闭合开关，记录电流 I 和电势差 V。计算电阻 R = V / I。改变长度重复实验，同时保持导线材料和温度不变。”
Common sources of error: zero errors on measuring instruments, parallax error when reading scales, thermal energy losses. Always mention how you can minimise them: use a set‑square to avoid parallax, insulate containers, take repeat readings and average.
常见误差来源：测量仪器的零点误差、读取刻度时的视差、热能的损失。要始终提及如何尽量减小这些误差：使用三角尺避免视差、对容器进行隔热处理、进行重复读数并取平均值。
When analysing data, show your calculations clearly. If the question asks 'Does the data support the prediction?', refer to the pattern in the results and any anomalous points.
分析数据时，要清晰地展示计算过程。如果问题问“数据是否支持预测？”，需指出的结果中的规律以及任何异常数据点。
8. Avoiding Common Mistakes | 避免常见错误
Many marks are lost through simple, avoidable errors. Being aware of them will help you guard against them.
许多分数都因一些简单、可避免的错误而丢失。意识到这些错误就能帮你加以防范。
weight: mass is measured in kg, weight in N. Weight = mass × gravitational field strength.
混淆质量与重量：质量以 kg 为单位，重量以 N 为单位。重量 = 质量 × 重力场强度。
Forgetting direction in vector quantities: velocity, acceleration, force and momentum have both magnitude and direction.
忘记矢量量的方向：速度、加速度、力和动量既有大小又有方向。
Misusing 'speed of light' value: it is 3.00 × 10⁸ m/s in a vacuum, not 3 × 10⁸ m/s without the unit.
误用“光速”数值：光在真空中的速度为 3.00 × 10⁸ m/s，而不是没有单位的 3 × 10⁸。
In circuit diagrams, forgetting to label components or drawing incorrect symbols for a diode or thermistor.
在电路图中忘记标注元件，或画错二极管、热敏电阻的符号。
momentum: p = mv, and always state the principle of conservation of momentum if using it.
动量公式使用错误：p = mv，并且使用动量守恒原理时要说明该原理。
When answering 'State one precaution', write a specific action, not a general aim. 'Repeat and average' is almost always a good answer for practical questions.
回答“写出一项预防措施”时，要写出具体的操作步骤，而非笼统的目标。“重复实验并取平均值”在实验题中几乎总是一个好答案。
9. Time Management in the Exam | 考试时间管理
Paper 4 is particularly time‑pressured: you have about 1.1 minutes per mark. Plan your time before you start.
试卷四的时间特别紧张：你每 1 分大约只有 1.1 分钟。开考之前先规划好时间。
Read through the whole paper during the first few minutes. Identify questions you can answer quickly and tackle those first to build confidence.
用最初几分钟通读整份试卷。找出你能快速作答的问题，优先完成这些题目，建立信心。
Do not spend more than one minute per mark on longer questions. If you get stuck, move on and return later. A partially answered question is better than an unanswered one.
在分值较高的题目上，不要每分花费超过一分钟。如果遇到困难，先跳过，之后再回来解答。部分作答总好过完全空白。
For multiple‑choice Paper 2, eliminate obviously wrong answers first. If you are unsure, mark the question and return to it if time allows.
对于选择题试卷二，先排除明显错误的选项。如果不确定，先标记该题，如果时间允许再返回检查。
In practical papers, allocate about 10 minutes at the end to check units, significant figures and graph details. Small corrections can rescue several marks.
在实验试卷中，最后留出大约 10 分钟检查单位、有效数字和图表细节。细微的纠正能挽回好几分。
10. Understanding the Mark Scheme | 理解评分方案
The CIE mark scheme is a detailed document that shows exactly how marks are awarded. Looking at past mark schemes is one of the most effective revision strategies.
CIE 评分方案是一份详细文件，精确展示了分数是如何分配的。查阅过往的评分方案是最有效的复习策略之一。
Mark schemes use abbreviations: 'M1' for method mark, 'A1' for accuracy mark, 'B1' for independent mark (often for a statement or definition), 'C1' for compensatory error follow‑through mark in calculations.
评分方案中会使用缩写：“M1”代表方法分，“A1”代表准确度分，“B1”代表独立分（通常针对陈述或定义），“C1”代表计算中因补偿性错误而给予的跟进分。
'Accept' and 'Ignore' tell you what alternative answers are awarded marks and which extra information is not penalised. The phrase 'DO NOT ACCEPT' highlights incorrect answers that candidates often give.
“接受”和“忽略”告诉你哪些其他答案能够得分，以及哪些额外信息不会被扣分。而“不接受”则明确指出考生常给出的错误答案。
For example, in a question on energy resources, 'renewable' might be awarded B1. But if you additionally write 'it is cheap', that might be irrelevant and ignored unless it contradicts the correct point.
例如，在能源资源的问题中，“可再生”可能获得 B1 分。但如果你额外写了“它很便宜”，这可能会被视为无关信息而被忽略，除非它与正确的观点相矛盾。
Practice with past papers and then mark your own work using the published mark scheme. This trains you to see your answers as an examiner would.
先用历年真题练习，然后用官方发布的评分方案给自己批改。这样能够训练你像阅卷官一样审视自己的答案。
11. Answering Extended Response Questions | 回答扩展回答题
Extended response questions, typically worth 4–6 marks, assess your ability to construct a coherent argument using scientific principles. They often appear at the end of a structured question in Paper 4.
扩展回答题通常分值在 4–6 分，考查你将各个科学原理连贯组织成论点的能力。它们常出现在试卷四结构化问题的末尾。
Start by reading the question carefully and underlining key physics concepts involved. In a question about a car braking distance, you might need to discuss thinking distance, braking distance, kinetic energy, friction, momentum and work done.
首先仔细读题，并在涉及的物理概念下划线。在一道关于汽车刹车距离的题目中，你可能需要讨论反应距离、刹车距离、动能、摩擦力、动量以及做功。
Plan your response as a short bullet‑point list in the margin. Then write in full sentences, using connectives: 'initially', 'as a result', 'consequently', 'this means that'.
在页边空白处用简短的要点列出你的回答计划。然后用完整的句子书写，使用连接词：“起初”、“因此”、“从而”、“这意味着”等。
Examiners award marks for each logical step. Even if you don' n of energy, for the equation KE = ½ mv², or for noting that work done = force × distance.
阅卷官为每一个逻辑步骤打分。即使没有得出最终结论，你仍然可以通过陈述能量守恒、写出表达式 KE = ½ mv²，或指出功 = 力 × 距离而获得分数。
Always link back to the context given in the question. If the question is about a roller‑ster, refer to gravitational potential energy = mgh and how it converts to kinetic energy.
始终要回扣题目给出的情境。如果问题关于过山车，要提及重力势能 = mgh，以及它如何转化为动能。
12. Final Revision Tips | 最后复习建议
Active revision is far more effective than passive reading. Use flashcards for definitions and formulas, draw mind maps for each topic (Mechanics, Thermal Physics, Waves, Electricity, Nuclear Physics, Space Physics) and explain concepts aloud.
主动复习比被动阅读有效得多。使用闪卡记忆定义和公式，为每个主题（力学、热物理、波、电学、核物理、空间物理）绘制思维导图，并大声讲解概念。
Complete at least five full past papers under timed conditions. Review every mistake and write down the correct physics principle or examination technique that would have earned the mark.
在限时条件下至少完成五套完整的历年真题。回顾每一个错误，并写下能帮你拿到分数的正确物理原理或考试技巧。
Form a study group and test each other on practical setups. Explaining to someone else forces you to organise your thoughts and exposes gaps in your understanding.
组织学习小组，互相测试实验装置。向他人讲解能迫使你组织思路，并暴露出理解上的漏洞。
Remember: the exam is not just a test of memory, but of how well you can apply what you know. With careful analysis of mark schemes and consistent practice of exam technique, you can walk into the exam hall confident and prepared.
请记住：考试不仅是对记忆力的测试，更是对你运用知识能力的检验。通过仔细分析评分方案和持续练习答题技巧，你便能自信、从容地走进考场。
