寒假是Year 7学生巩固物理知识、查漏补缺、为新学期建立信心的黄金机会。一份有条理的强化复习计划可以把假期变成高效学习期，而不会让学生感到负担过重。本指南根据CIE Year 7物理课程量身定制，涵盖核心主题、高效学习方法和每周时间安排，帮助每一位学习者充分利用假期时间。
1. Setting Goals for Your Winter Revision | 制定寒假复习目标
Before opening any textbook, sit down and identify what you want to achieve by the end of the winter break. Do you need to strengthen your understanding of forces, improve your calculation skills, or simply review all topics to be ready for class tests? Write down two or three clear, realistic goals, such as ‘I will be able to explain how friction works with real-life examples’ or ‘I will complete 20 practice questions on energy transfers without help’. Having specific targets keeps your revision focused and gives you a sense of progress.
在打开课本之前，先坐下来想一想寒假结束时你想达成什么目标。你是需要加强对力的理解，提高计算能力，还是简单地复习所有主题以便应对课堂测验？写下两到三个清晰、现实的目标，例如“我能用生活实例解释摩擦力的作用”或“我能独立完成20道关于能量转移的练习题”。有了具体的目标，复习才会有的放矢，也能让你感受到进步。
2. Understanding the CIE Year 7 Physics Syllabus | 了解CIE Year 7物理考纲
The CIE Year 7 Physics syllabus is designed to build a strong foundation in scientific thinking and enquiry. Key topics usually include forces and motion, energy, electricity, magnetism, and waves (sound and light). There may also be an introduction to Earth and space. Familiarise yourself with the official topic list or your school’s scheme of work. This ensures that no important concept is overlooked during the holidays. You can ask your teacher for a syllabus outline or check the Cambridge Lower Secondary Science curriculum framework.

Adjust the timetable to fit your holiday plans and energy levels. The key is to touch physics regularly, even if the session is short.
根据自己的假期安排和精力调整时间表。关键在于每天都接触一点物理，哪怕时间很短。
4. Topic 1: Forces and Motion | 主题1：力与运动
In Year 7, you learn that forces are pushes or pulls that can change the speed, direction, or shape of an object. Start by classifying forces into contact forces (friction, tension, normal force) and non-contact forces (gravity, magnetic force). Draw simple free-body diagrams to represent forces acting on a stationary box or a moving car. Make sure you can calculate average speed using the equation:
在Year 7，你将学到力是推或拉的作用，能改变物体的速度、方向或形状。先从将力分为接触力（摩擦力、张力、法向力）和非接触力（重力、磁力）开始。画简单的受力分析图，表示作用在静止箱子或运动汽车上的力。确保你能使用下面公式计算平均速度：
average speed = distance travelled / time taken (v = s / t)
平均速度 = 走过的距离 ÷ 所用的时间 (v = s / t)
Practise unit conversions, for example from minutes to seconds or from kilometres to metres. Also, explore unbalanced forces leading to acceleration or deceleration, and balanced forces resulting in constant speed or rest. Use toy cars or online simulations to visualise these concepts.
练习单位换算，例如分钟换算成秒，千米换算成米。同时探讨非平衡力导致加速或减速，平衡力导致物体保持匀速或静止。可以利用玩具小车或在线模拟来将这些概念形象化。
5. Topic 2: Energy | 主题2：能量
Energy is a central theme. You should be able to identify different energy stores: kinetic, gravitational potential, chemical, thermal (internal), elastic potential, and nuclear. Understand how energy is transferred between stores via pathways such as heating, waves, electric current, and forces doing work. For example, when a ball is dropped, gravitational potential energy decreases as kinetic energy increases, with some energy transferred to the surroundings as thermal energy.
能量是一个核心主题。你应当能辨认不同的能量储存方式：动能、重力势能、化学能、热能（内能）、弹性势能和核能。理解能量如何通过加热、波动、电流和力做功等途径在储存方式之间转移。例如，球下落时，重力势能减少、动能增加，同时一部分能量以热能形式转移至周围环境。
Use the idea of energy conservation: ‘Energy cannot be created or destroyed, only transferred.’ Create flow diagrams to show energy changes in devices like a torch or a wind-up toy. Practice simple calculations involving efficiency:
运用能量守恒思想：“能量既不会凭空产生，也不会凭空消失，只会转移。”画出能量流向图，展示手电筒或发条玩具中的能量变化。练习涉及效率的简单计算：
efficiency = useful output energy transfer / total input energy transfer
效率 = 有用的输出能量转移 ÷ 总的输入能量转移
Remember that efficiency can be given as a decimal or a percentage. Apply these ideas to real-world situations like light bulbs or solar panels.
记住效率可用小数或百分数表示。将这些概念应用到灯泡或太阳能电池板等实际情境中。
6. Topic 3: Electricity | 主题3：电学
Start with the basics: recognise common circuit symbols for cells, batteries, switches, bulbs, resistors, and buzzers. Be able to draw and interpret simple series circuits. Understand that current is the flow of electric charge around a circuit, and that a complete conducting loop is required for current to flow. In Year 7, you don’t need to calculate current or resistance, but you should know that adding more bulbs in series makes them dimmer because the energy is shared.
从基础开始：辨认电池、电源组、开关、灯泡、电阻和蜂鸣器等常见电路符号。能够画出并解释简单的串联电路。理解电流是电荷在回路中的流动，并且需要完整的导电回路才会有电流。在Year 7阶段不需要计算电流或电阻，但应当知道串联更多灯泡会使其变暗，因为能量被分摊了。
Explore conductors and insulators. Test which materials allow electricity to pass through using a simple circuit with a gap and a material to test. Always relate electricity to safety: never play with mains sockets, and always ask an adult when experimenting. You can also build circuits using simulation software like PhET to see how changing components affects brightness or buzzer volume.
探究导体和绝缘体。用一个留有空隙的简单电路测试各种材料，看哪些能让电流通过。始终将电学与安全联系起来：千万不要玩弄电源插座，做实验时一定要有成人陪同。你也可以使用PhET等模拟软件搭建电路，观察更换元件如何影响灯泡亮度或蜂鸣器音量。
7. Topic 4: Magnetism | 主题4：磁学
Magnetism is often one of the most enjoyable topics. Learn that magnets have two poles (north and south) and that like poles repel while unlike poles attract. Investigate which materials are magnetic (iron, nickel, cobalt, and some alloys like steel). Understand that a magnet can attract magnetic materials without touching them because of its magnetic field.
磁学通常是最有趣的主题之一。知道磁铁有两个极（北极和南极），同极相斥、异极相吸。探究哪些材料有磁性（铁、镍、钴以及钢等某些合金）。理解磁铁无需接触就能吸引磁性材料，这是因为它周围存在磁场。
Draw magnetic field lines using iron filings or a plotting compass. Recognise that the Earth itself acts like a giant magnet, which is why a compass needle points north. Practise predicting whether two magnets will attract or repel when placed in different orientations. Make a simple electromagnet using a nail, insulated wire, and a battery to see the link between electricity and magnetism.
用铁屑或小磁针绘制磁场线。认识到地球本身就像一个巨大的磁铁，这就是指南针指向北方的原因。练习预测两个磁铁在不同方位下会相吸还是相斥。用一个钉子、绝缘导线和电池制作一个简易电磁铁，直观感受电与磁的联系。
8. Topic 5: Waves – Sound and Light | 主题5：波——声音与光
Waves transfer energy without transferring matter. You will learn about transverse waves in the context of light and longitudinal waves for sound. Key vocabulary includes amplitude, wavelength, frequency, and wave speed. In Year 7, you are expected to label these features on a diagram and describe how changing amplitude affects loudness (sound) or brightness (light).
波传递能量而不传递物质。你将学到光是横波，声音是纵波。关键术语包括振幅、波长、频率和波速。在Year 7阶段，你需要能够在波形图上标出这些特征，并能描述振幅变化如何影响音量（声音）或亮度（光）。
For sound, explore how it travels through solids, liquids, and gases but not through a vacuum. Link the speed of sound to the state of matter. For light, understand that it travels in straight lines and can be reflected by mirrors. Draw ray diagrams to show how we see objects and how shadows form. Use a protractor to investigate the law of reflection: angle of incidence = angle of reflection.
对于声音，探究声音如何在固体、液体和气体中传播，但无法在真空中传播。将声速与物质状态联系起来。对于光，理解光沿直线传播，并能被镜子反射。画光路图来表示我们如何看到物体以及影子如何形成。使用量角器探究反射定律：入射角 = 反射角。
angle of incidence (i) = angle of reflection (r)
入射角(i) = 反射角(r)
These foundational ideas prepare you for more detailed wave studies later.
这些基础概念为日后更深入的波动学习做好准备。
9. Common Mistakes and How to Avoid Them | 常见错误及如何避免
Year 7 students often confuse weight and mass. Remember, mass is measured in kilograms (kg) and does not change, whereas weight is a force measured in newtons (N) and depends on gravity. Another typical error is mixing up current and energy in circuits – current is the flow of charge, not used up. In forces, failing to draw arrows in the correct direction or not labelling forces can lose marks. For energy, many learners forget that energy is transferred, not ‘used up’ in the sense of disappearing. Make a habit of checking units: always give speed in m/s, distance in m, time in s unless the question states otherwise. Keep a ‘mistakes log’ during revision to note down these pitfalls and how to correct them.
Year 7学生经常混淆重量和质量。记住，质量以千克(kg)为单位且不变，而重量是以牛顿(N)为单位的力，取决于重力。另一个典型错误是把电路中的电流和能量混为一谈——电流是电荷的流动，不会被消耗。在力的部分，箭头方向画错或不标注力会丢分。在能量方面，许多同学忘记能量是转移而不是“用光”消失。养成检查单位的习惯：除非题目另有说明，速度用m/s、距离用m、时间用s。复习时准备一本“错题记录”，记下这些易错点及其改正方法。
10. Using Past Papers and Practice Questions | 使用历年真题和练习题
Past papers and topic-specific question banks are some of the most effective revision tools. Start with questions that target one topic at a time, so you can check understanding before mixing them. When you attempt a question, write down your answer fully, then compare it with the model answer to see where marks are given. Pay attention to command words: ‘state’ means give a short answer, ‘describe’ means write about what happens, and ‘explain’ means give reasons why. Time yourself to build exam confidence. You can find suitable practice materials from Cambridge Checkpoint Science papers or teacher-prepared worksheets.
历年真题和分主题的题库是最有效的复习工具之一。先从针对单一主题的题目入手，检查理解情况，再尝试综合性题目。做题时，完整写出答案，然后与标准答案对比，看看得分点在哪里。注意题干中的答题指令词：“state”要求简短作答，“describe”要求描述发生了什么，“explain”要求解释原因。计时练习，培养考试信心。你可以从剑桥Checkpoint科学试卷或老师准备的练习页中找到合适的练习材料。
11. Practical Skills and Simple Experiments | 实验技能与简易实验
Physics is an experimental subject, and CIE values practical enquiry. Even during the winter break, you can carry out simple, safe experiments at home. For example, use a spring and some weights to investigate Hooke’s law: how the extension of a spring increases with force. Record your results in a table, plot a graph, and write a conclusion. This helps you practise handling data, identifying patterns, and discussing errors. Other easy activities include building a series circuit with a battery and a bulb, making a pinhole camera to understand light, or timing a pendulum to explore periodic motion. Remember to always ask an adult before starting any experiment.
物理是一门实验学科，CIE重视实验探究能力。就算在寒假里，你也可以在家进行简单、安全的实验。例如，用一根弹簧和一些砝码研究胡克定律：弹簧的伸长量如何随力而增加。将结果记录在表格中，绘制图表，并写出结论。这能帮助你练习处理数据、识别规律和讨论误差。其他简单的活动包括用电池和灯泡搭建串联电路、制作针孔相机来理解光、或者用单摆计时探究周期运动。切记，任何实验开始前都要征得成人同意。
12. Staying Motivated and Managing Time | 保持动力和时间管理
Holiday revision can feel lonely or boring if you don’t balance it with rest and fun. Break your study sessions into chunks using the Pomodoro technique: 25 minutes of focused work, then a 5-minute break. Reward yourself after completing a topic – perhaps a snack, a short walk, or playing a game. Keep your study space tidy and free from distractions. If you find a concept difficult, try teaching it to a sibling or a stuffed toy; explaining aloud often clarifies your own thinking. Stay in touch with friends who are also revising, so you can ask each other questions. Remember, the goal is not to spend hours hunched over books but to use the time wisely so you return to school feeling confident and prepared.
假期复习如果不懂得劳逸结合，很容易感到孤单或无聊。采用番茄工作法把学习分成小段：25分钟专注学习，然后休息5分钟。每完成一个主题就奖励自己一下——吃点零食、散个步、或者玩会儿游戏。保持学习空间整洁、远离干扰。如果遇到难懂的概念，试着讲给兄弟姐妹或毛绒玩具听；大声讲解常常能理清自己的思路。与其他也在复习的同学保持联系，互相提问。记住，目标不是在书本前埋头苦读数小时，而是善用时间，让自己回到学校时充满信心、做好准备。
