很多同学会搜索 "IGCSE biology notes 物理 复习 笔记"，原因很简单：生物和物理要同时复习，却希望有一套统一、可靠的笔记把两门课整理清楚。本文会系统讲解如何搭建、使用和复习剑桥 IGCSE 生物与 IGCSE 物理的电子版笔记，包括两科的核心考纲框架、高频考点、物理公式、实验技能、中英双语术语表以及可执行的复习时间表。同时也会说明电子版资料包含哪些内容，以及对应的售后政策。
1. Why Biology and Physics Need Different Notes | 为什么生物和物理需要不同的笔记方法
Biology is a subject of description, sequence and cause-and-effect. Marks come from naming the right structure, stating the correct function, and explaining what happens if a step is missing. Physics is a subject of quantities, equations and units. Marks come from choosing the right relationship, substituting correctly, and giving the answer with the right unit and reasonable significant figures. A single notebook layout therefore wastes time: one demands long written chains, the other demands compact symbol work.
生物是"描述 + 顺序 + 因果"的学科，得分点在于写对结构名称、说明正确功能，并解释"如果某一步缺失会发生什么"。物理是"物理量 + 公式 + 单位"的学科，得分点在于选对关系式、正确代入数值，并给出单位正确、有效数字合理的答案。因此如果用同一种笔记格式硬套两科，效率会很低：一科需要成段的文字链条，另一科需要紧凑的符号运算。
The practical solution is a two-layer system: a shared index page at the front, then two clearly separated note blocks. The index lists every syllabus topic with a page number and a confidence rating from 1 to 3. This lets you see at a glance which topics are already secure and which still need another pass before the exam.
最实用的方案是"两层结构"：前面一页共用目录，后面分成两块清晰隔离的笔记区。目录上列出每个考纲主题、页码，以及 1 至 3 级的掌握程度自评。这样一眼就能看出哪些主题已经稳了，哪些在考前还需要再过一遍。
- Biology block: processes, structures, definitions, diagrams, data questions. | 生物区：过程、结构、定义、图表、数据分析题。
- Physics block: equations, units, graph shapes, practical methods, error discussion. | 物理区：公式、单位、图像形状、实验方法、误差讨论。
2. The Core Framework of IGCSE Biology Notes | IGCSE 生物笔记的核心框架
Cambridge IGCSE Biology (0610 / 0970) is organised into a predictable sequence: characteristics of living organisms; cells; enzymes; nutrition in plants and animals; transport; gas exchange; respiration; excretion; coordination and response; reproduction; inheritance; variation and selection; organisms and their environment; and biotechnology. Each of these deserves one double page in your notes, with the syllabus learning outcomes copied into the margin as a checklist.
剑桥 IGCSE 生物（0610 / 0970）的编排顺序非常稳定：生物的特征；细胞；酶；植物与动物的营养；运输；气体交换；呼吸作用；排泄；协调与反应；生殖；遗传；变异与选择；生物与环境；生物技术。每一个主题在笔记里都值得占一个双页，并把考纲学习目标抄在页边作为检查清单。
For every process, write it as a flow rather than a paragraph. A flow forces you to remember order, which is exactly what examiners reward. For example, digestion of starch should appear as a chain from mouth to small intestine, with the enzyme, the substrate, the product and the optimum pH written under each arrow.
每一个生理过程都要写成流程，而不是一段散文。流程图会强迫你记住顺序，而顺序恰恰是考官给分的地方。例如淀粉的消化，应当从口腔到小肠写成一条链，在每个箭头下方标注酶、底物、产物和最适 pH。
Starch → maltose → glucose (amylase, then maltase)
Also record the limiting factors for each rate-based topic. Photosynthesis and enzyme activity are the two topics where students most often lose marks simply because they describe the trend but never name the limiting factor.
凡是涉及"速率"的主题，都要记录限制因素。光合作用和酶活性是最容易丢分的两块，因为学生往往只描述了趋势，却没有指出限制因素是什么。
3. High-Frequency Biology Topics and Memory Tricks | 生物高频考点与记忆技巧
Enzymes, osmosis, photosynthesis and respiration appear in almost every paper. Learn the definitions word for word, then learn one worked example for each. The lock-and-key model should be described with the words active site, substrate, complementary shape and denaturation at high temperature or extreme pH.
酶、渗透、光合作用和呼吸作用几乎每份试卷都会出现。定义要逐字背熟，然后每个概念配一个标准例子。"锁钥模型"的描述必须包含以下关键词：活性位点、底物、互补形状，以及高温或极端 pH 下的变性。
For osmosis, always state the direction of water movement in terms of water potential, not just "from high to low concentration". Water moves from a region of higher water potential to a region of lower water potential through a partially permeable membrane.
谈到渗透，一定要用水势来描述水的移动方向，而不能只写"从高浓度到低浓度"。水通过半透膜，从水势较高的区域移动到水势较低的区域。
The two gas equations are worth memorising as balanced symbols, because many candidates lose the balancing mark even when the word equation is correct.
两个气体相关的方程式值得用符号形式背熟，因为很多考生即使文字方程式写对了，也会丢掉配平分。
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O (+ energy)
Memory tricks that work for IGCSE biology are usually spatial or narrative, not alphabetical. Draw the leaf cross-section until you can label cuticle, upper epidermis, palisade mesophyll, spongy mesophyll, vascular bundle, lower epidermis and stomata without looking. Then write one sentence for each layer explaining its job.
对 IGCSE 生物真正有效的记忆法，通常是空间型或叙事型，而不是按字母排序。把叶片横切面画到闭眼也能标出角质层、上表皮、栅栏组织、海绵组织、维管束、下表皮和气孔为止，然后为每一层写一句话说明它的作用。
4. Biology Diagrams, Practicals and Command Words | 生物图表、实验题与指令词
Diagrams in IGCSE Biology must be large, clear and drawn with a sharp pencil, with label lines that touch the structure and never cross each other. Labels should be written horizontally outside the drawing. Do not shade unless the question asks for it, and never use colour to replace a label.
IGCSE 生物的作图必须够大、清晰，用削尖的铅笔绘制；标注线要接触到对应结构，且彼此不能交叉。标注文字应水平写在图形外侧。除非题目明确要求，否则不要涂阴影，也绝不能用颜色代替标注。
Practical questions almost always test the same four things: identifying the independent variable, identifying the dependent variable, naming one controlled variable, and suggesting an improvement. Write these four as a template at the top of your practical notes so you can answer mechanically under time pressure.
实验题几乎永远在考同样的四件事：找出自变量、找出因变量、写出一项控制变量、提出一条改进建议。把这四点写成模板放在实验笔记的开头，考场上就能在时间压力下机械地作答。
Command words decide how much you write. "State" needs one short line. "Describe" needs a sequence of observations or steps. "Explain" needs a cause and a consequence, often with the word "because". "Suggest" means the answer is not in the textbook and must be reasoned from the data given.
指令词决定了你要写多少。"State（写出）"只需一行短答；"Describe（描述）"需要写出观察或步骤的顺序；"Explain（解释）"需要给出原因和结果，通常要用到"because（因为）"；"Suggest（提出）"意味着答案不在教材里，必须根据所给数据推理得出。
5. The Core Framework of IGCSE Physics Notes | IGCSE 物理笔记的核心框架
Cambridge IGCSE Physics (0625 / 0972) covers motion, forces and energy; thermal physics; waves; electricity and magnetism; nuclear physics; and space physics. The notes for each topic should be built around three columns: quantity and symbol, defining equation, and unit with typical exam values.
剑桥 IGCSE 物理（0625 / 0972）涵盖运动、力与能量、热物理、波、电与磁、核物理以及天体物理。每个主题的笔记都应围绕三栏展开：物理量与符号、定义式、单位及常见考试数值。
Because physics marks are lost mainly through unit and substitution errors, always write the equation first, then rearrange it symbolically, then substitute numbers. Writing numbers too early is the single most common cause of avoidable mistakes in Paper 4 and Paper 6.
物理失分主要来自单位和代入错误，所以永远先写公式，再做符号变形，最后代入数字。过早代入数字，是 Paper 4 和 Paper 6 中最常见、也最不该发生的错误来源。
v = s ÷ t a = Δv ÷ Δt F = m × a
ρ = m ÷ V p = F ÷ A p = h × ρ × g
Keep a separate half-page called "definitions I keep forgetting", updated after every past paper. Typical entries include centre of mass, moment, specific heat capacity, latent heat, frequency, wavelength, electromotive force and half-life.
单独留半页，标题写"我总忘的定义"，每做完一套真题就补充更新。常见条目包括质心、力矩、比热容、潜热、频率、波长、电动势和半衰期。
6. Physics Equations and Units You Must Memorise | 必须背熟的物理公式与单位
The IGCSE Physics equation sheet is generous, but fluency matters more than access. You should be able to recall and rearrange the core equations without hesitation, because Paper 4 rewards speed and Paper 6 rewards precise method.
IGCSE 物理会提供公式表，但熟练度比"能查到"更重要。核心公式必须能不假思索地回忆并变形，因为 Paper 4 奖励速度，Paper 6 奖励精确的方法。
| Quantity | 物理量 | Equation | 公式 | Unit | 单位 |
|---|---|---|
| Speed | 速率 | v = s ÷ t | m/s |
| Acceleration | 加速度 | a = Δv ÷ Δt | m/s² |
| Force | 力 | F = m × a | N |
| Kinetic energy | 动能 | Eₖ = ½ × m × v² | J |
| Ohm's law | 欧姆定律 | V = I × R | V |
| Wave speed | 波速 | v = f × λ | m/s |
Unit discipline is not optional. Convert grams to kilograms and centimetres to metres before substituting. A correct method with the wrong power of ten is still a wrong answer, and it is the fastest way to drop two or three marks in one question.
单位规范不是可选项。代入前必须把克换成千克、厘米换成米。方法正确但数量级错了，答案依然是错的，而且这是一道题里丢掉两三分最快的方式。
Efficiency η = (useful energy output ÷ total energy input) × 100%
7. Graphs, Practical Skills and Significant Figures | 物理图像、实验技能与有效数字
Graph questions in IGCSE Physics test three separate skills: plotting points accurately, drawing a line or curve of best fit, and interpreting the gradient or area. Always label axes with quantity and unit, and choose a scale that uses at least half of the grid.
IGCSE 物理的图像题考查三项独立技能：准确定点、画出最佳拟合直线或曲线、解读斜率或面积。坐标轴必须标注物理量和单位，并且刻度要让图形至少占满网格的一半。
Learn the standard interpretations once and reuse them. On a distance-time graph, the gradient is speed. On a velocity-time graph, the gradient is acceleration and the area under the line is distance travelled. On a current-voltage graph, the gradient is 1 ÷ R.
把这些标准解读一次学透，之后反复套用。位移-时间图中，斜率是速率；速度-时间图中，斜率是加速度，线下面积是位移；电流-电压图中，斜率是 1 ÷ R。
Paper 6 also asks you to discuss uncertainty. Quote the smallest division of the instrument, repeat readings and average them, and identify the variable that was hardest to control. Generic answers such as "human error" score nothing; name the specific quantity and the specific improvement.
Paper 6 还会要求讨论不确定度。要写明仪器的最小分度值、重复测量并取平均，并指出最难控制的变量。像"人为误差"这样的泛泛表述不得分，必须写出具体的物理量和具体的改进方法。
8. Bilingual Terminology: Building a Working Glossary | 双语术语：建立可用的术语表
If you study in Chinese but sit the exam in English, terminology is often the real barrier rather than the science. Build a three-column glossary: English term, Chinese meaning, and one short English sentence using the term in an exam context. The third column is what turns passive recognition into active recall.
如果你用中文学习、用英文考试，真正的障碍往往是术语而不是科学本身。建议做三栏术语表：英文术语、中文含义、以及在考试语境中使用该术语的一句英文短句。第三栏是把"被动认得"变成"主动回忆"的关键。
- Partially permeable membrane | 半透膜 | Water moves through a partially permeable membrane by osmosis.
- Limiting factor | 限制因素 | Light intensity is the limiting factor when the rate stops increasing.
- Resultant force | 合力 | A resultant force of zero means constant velocity.
- Specific heat capacity | 比热容 | Specific heat capacity is the energy needed to raise 1 kg by 1 °C.
Review the glossary using spaced repetition: day 1, day 3, day 7, day 21. Cover the Chinese column, say the meaning aloud, then cover the English column and write the term from memory.
术语表要用间隔重复来复习：第 1 天、第 3 天、第 7 天、第 21 天。遮住中文栏，说出含义；再遮住英文栏，凭记忆写出术语。
9. Building a Revision Timetable with Active Recall | 用主动回忆法搭建复习时间表
Reading notes again feels productive but produces very little learning. Replace re-reading with retrieval: close the notes, write down everything you remember about a topic on a blank page, then reopen the notes and mark what you missed in a different colour.
反复读笔记让人感觉很有收获，但实际学习效果很低。要用"提取"替代"重读"：合上笔记，在空白纸上写出你记得的关于该主题的一切，然后打开笔记，用另一种颜色标出遗漏的内容。
A workable weekly cycle alternates subjects so that neither is neglected and neither becomes boring. Biology benefits from morning slots when you can write long answers; physics benefits from shorter, timed sets where you practise rearranging equations.
一个可执行的每周循环应当交替安排两科，既不偏废，也不至于枯燥。生物适合安排在早晨，因为你能写长答案；物理适合用短时、计时的题组，专门练公式变形。
| Day | 星期 | Focus | 重点 | Method | 方法 |
|---|---|---|
| Mon | 周一 | Biology: enzymes and transport | 生物：酶与运输 | Blank-page recall | 空白纸回忆 |
| Tue | 周二 | Physics: motion and forces | 物理：运动与力 | Timed equations | 计时公式题 |
| Wed | 周三 | Biology: photosynthesis | 生物：光合作用 | Diagram from memory | 默画图表 |
| Thu | 周四 | Physics: waves and optics | 物理：波与光学 | Graph interpretation | 图像解读 |
| Fri | 周五 | Mixed past paper section | 混合真题 | Mark with scheme | 按评分标准批改 |
10. Common Mistakes and the Final Seven Days | 常见误区与考前七天冲刺
The most common biology mistakes are vague function statements, missing units in data questions, and diagrams without labels touching the structure. The most common physics mistakes are forgetting to convert units, using the diameter instead of the radius, and quoting too many significant figures.
生物最常见的错误是功能描述含糊、数据题不写单位、以及标注线没有接触到结构。物理最常见的错误是忘记换算单位、把直径当半径用、以及给出的有效数字过多。
In the final seven days, do not start new topics. Instead, work through one full past paper per day under timed conditions, then spend twice as long marking it with the official scheme. Write every lost mark into a single "error log" page; the same three or four errors usually account for most of the gap between grades.
最后七天不要开新主题。每天限时完成一套完整真题，然后用两倍的时间对照官方评分标准批改。把每一处失分写进同一页"错题日志"；分数差距通常就来自那三四个反复出现的错误。
Two days before the exam, stop writing long answers and review only your error log, your glossary and your equation list. Sleep is part of the preparation, not a break from it.
考前两天，停止写长答案，只复习错题日志、术语表和公式清单。睡眠是备考的一部分，而不是备考之外的事情。
