掌握科学词汇不仅仅是死记硬背，它关乎建立联系、识别模式以及运用巧妙的记忆技巧。对于 Year 11 CAIE 科学课程的学生来说，扎实的术语功底能够为你打开生物、化学和物理考试的成功之门。本指南提供了实用、紧扣考点的策略，帮助你快速记忆复杂术语并长期保持。
1. The Power of Roots, Prefixes and Suffixes | 词根词缀的力量
Scientific vocabulary is built from Greek and Latin roots. If you learn the most common building blocks, you can often decode unfamiliar terms on the spot. ‘Photosynthesis’ breaks down into ‘photo-‘ (light) and ‘synthesis’ (putting together). Once you know these parts, the word instantly makes sense: putting together using light.
科学词汇由希腊语和拉丁语词根构成。如果你学会了最常见的构词模块，往往可以当场解码陌生术语。’Photosynthesis’（光合作用）可拆分为 ‘photo-‘（光）和 ‘synthesis’（组合）。一旦你掌握了这些部分，这个词瞬间就变得清晰：利用光进行组合。
Make a habit of dissecting every new term you encounter. For example, ‘hydrolysis’ uses ‘hydro-‘ (water) and ‘-lysis’ (splitting). Similarly, ‘endothermic’ combines ‘endo-‘ (inside) and ‘thermic’ (heat). By collecting prefixes and suffixes, you build a reusable mental toolkit that works across all three sciences.
养成拆分每个新术语的习惯。例如，’hydrolysis’（水解）使用了 ‘hydro-‘（水）和 ‘-lysis’（分解）。类似地，’endothermic’（吸热）结合了 ‘endo-‘（内部）和 ‘thermic’（热）。通过收集前缀和后缀，你可以搭建一个可重复使用的思维工具箱，适用于全部三门科学学科。
2. Common Prefixes in Science | 科学常用前缀
Focus on high-frequency prefixes that appear repeatedly in IGCSE papers. ‘Mono-‘ (one), ‘di-‘ (two), ‘poly-‘ (many) are essential in Chemistry for naming compounds like carbon dioxide (CO₂) or polymers. ‘Hyper-‘ (over, above) and ‘hypo-‘ (under, below) appear in Biology with terms such as hypertonic and hypotonic solutions. In Physics, ‘electro-‘ (electric) gives us electromagnet and electrostatic.
重点关注在 IGCSE 试卷中反复出现的高频前缀。’Mono-‘（一）、’di-‘（二）、’poly-‘（多）在化学中对于命名化合物（如二氧化碳 CO₂ 或聚合物）至关重要。’Hyper-‘（超过）和 ‘hypo-‘（低于）出现在生物学的 ‘hypertonic’（高渗）和 ‘hypotonic’（低渗）等术语中。在物理中，’electro-‘（电）衍生出电磁体和静电等词。
Create a prefix wall chart and add an example for each. For instance, ‘thermo-‘ (heat) → thermometer, exothermic. ‘Aero-‘ (air) → aerobic respiration. This visual aid turns passive recognition into active recall, especially when you draw quick symbols next to each prefix.
创建一个前缀挂图，并为每个前缀添加一个例子。例如，’thermo-‘（热）→ 温度计、放热；’aero-‘（空气）→ 有氧呼吸。这种视觉辅助工具能将被动识别转化为主动回忆，尤其是在每个前缀旁绘制简单的符号时。
3. Key Suffixes for Processes and Conditions | 过程与状态的关键后缀
Suffixes signal the type of word you are dealing with. ‘-osis’ often indicates a condition or process: mitosis, osmosis, phagocytosis. In Chemistry, ‘-ide’ denotes a binary compound (sodium chloride), while ‘-ate’ and ‘-ite’ indicate oxyanions (sulfate, sulfite). ‘-lysis’ and ‘-synthesis’ are direct opposites, making them a perfect pair to learn together.
后缀暗示着单词的类型。’-osis’ 通常表示一种状态或过程：有丝分裂、渗透、吞噬作用。在化学中，’-ide’ 表示二元化合物（氯化钠），而 ‘-ate’ 和 ‘-ite’ 表示含氧阴离子（硫酸盐、亚硫酸盐）。’-lysis’（分解）和 ‘-synthesis’（合成）是直接反义词，将它们放在一起学习非常有效。
Turn suffix learning into a sorting game. Write a list of terms on cards and group them by ending. As you sort, say aloud what the suffix means. For example, ‘haemolysis’—splitting of red blood cells. This multi-sensory method strengthens the link between the word part and its meaning.
将后缀学习变为分类游戏。把术语写在卡片上，并按词尾进行分组。在分类时，大声说出后缀的含义。例如，’haemolysis’——红细胞的破裂。这种多感官方法能强化构词部分与其含义之间的联系。
4. Memory Palace for Biology Organelles | 记忆宫殿记生物学细胞器
Biology is packed with organelles, each with a specific function. Place them in a memory palace: imagine walking through your home and assigning each room to an organelle. The kitchen is the mitochondria because it produces energy (ATP). The control centre or living room could be the nucleus, storing the master plan (DNA). The recycling bin by the door represents lysosomes, breaking down waste.
生物学中有大量细胞器，每个都有特定功能。将它们放置在记忆宫殿中：想象你穿过自己的家，把每个房间分配给一个细胞器。厨房是线粒体，因为它产生能量（ATP）。控制中心或客厅可以是细胞核，储存着总蓝图（DNA）。门口的回收箱代表溶酶体，负责分解废物。
Make the images vivid and exaggerated. Picture ribosomes as tiny chefs assembling protein dishes in the kitchen. The cell membrane becomes the front door with security guards that control what enters and exits. When you need to recall functions during the exam, simply walk through your palace mentally.
让画面生动而夸张。把核糖体想象成在厨房里装配蛋白质菜肴的小厨师。细胞膜则成为配有保安的前门，控制出入。当你在考试中需要回忆功能时，只需在脑海中漫步你的宫殿。
5. Visual Mnemonics for Physics Equations | 物理公式的视觉记忆法
Physics equations can feel abstract, but turning them into a memorable picture helps. For the density equation, remember a heart-shaped box: D = m/V. The ‘m’ sits on top of the ‘V’ like a love heart, reminding you that density is mass divided by volume. For the wave equation v = f × λ, imagine a flying fox: the velocity (v) rides on frequency (f) and wavelength (λ) as if they are wings.
物理公式可能感觉抽象，但将其转化为难忘的图像会很有帮助。对于密度公式，记住一个心形盒子：D = m/V。’m’ 坐在 ‘V’ 上方，像一颗爱心，提醒你密度是质量除以体积。对于波动方程 v = f × λ，想象一只飞狐：速度 (v) 骑在频率 (f) 和波长 (λ) 之上，仿佛它们是翅膀。
D = m / V | v = f × λ | F = m × a
Pair equations with a simple sketch on your revision notes. For Ohm’s law, V = I × R, draw a voltage tower built from current and resistance blocks. For kinetic energy Eₖ = ½mv², sketch a moving car with half its mass and squared speed arrows. Symbols become anchors for your memory.
在复习笔记中将公式与简单草图配对。对于欧姆定律 V = I × R，画一座由电流和电阻块建成的电压塔。对于动能 Eₖ = ½mv²，画一辆带有半质量和平方速度箭头的运动汽车。符号会成为你记忆的锚点。
6. Chunking Chemical Nomenclature | 化学命名的组块化记忆
Chemical names can look intimidating, but they become manageable when you chunk them. Take ‘2-methylpropane’ and split it into: position number (2-), substituent (methyl), parent chain (prop), and alkane suffix (-ane). Practice this chunking on different organic molecules. Soon, naming compounds feels like assembling a puzzle with familiar pieces.
化学名称可能看起来令人生畏，但当你将其组块化时，它们就变得易于管理。以 ‘2-甲基丙烷’ 为例，将其拆分为：位置编号 (2-)、取代基 (甲基)、主链 (丙) 和烷烃后缀 (-烷)。在不同的有机分子上练习这种组块化。很快，命名化合物就像用熟悉的碎片组装拼图一样。
Use colour-coded highlighting for each chunk. For ‘iron(III) sulfate’, highlight the metal in one colour, the oxidation state in another, and the polyatomic ion in a third. This visual separation trains your brain to see the structure behind the name, reducing errors in balancing equations and writing formulae.
为每个组块使用彩色高亮标记。对于 ‘硫酸铁(III)’，用一种颜色高亮金属，用另一种颜色标出氧化态，用第三种颜色标出多原子离子。这种视觉分离能训练你的大脑看到名称背后的结构，减少配平方程和书写化学式时的错误。
7. Making Connections with Everyday Words | 与日常词汇建立联系
Many scientific terms have everyday cousins. ‘Diffusion’ sounds like ‘diffuse’ (spread out) and describes particles moving from high to low concentration. ‘Precipitate’ relates to ‘precipitation’ (rain) in weather, hinting at a solid forming and falling out of solution. Building these bridges makes recall almost automatic.
许多科学术语都有日常用法中的近亲。’Diffusion’（扩散）听起来像 ‘diffuse’（散布），描述粒子从高浓度区域向低浓度区域移动。’Precipitate’（沉淀物）与天气中的 ‘precipitation’（降水）相关，暗示固体从溶液中形成并沉降。搭建这些桥梁能让回忆几乎自动完成。
Create a ‘science in real life’ page in your notebook. Write down where you see concepts in action: evaporation in a drying puddle, condensation on a cold glass, oxidation on a rusty nail. Personal associations deepen understanding and make vocabulary stick far better than isolated study.
在笔记本中创建一个“生活中的科学”页面。写下你在何处看到这些概念的实际应用：水坑蒸发、冷玻璃杯上的冷凝、生锈钉子上的氧化。个人联想能加深理解，使词汇比孤立学习时牢固得多。
8. Flashcard Strategies and Active Recall | 闪卡策略与主动回忆
Flashcards remain one of the most effective tools when used correctly. On one side, write the scientific term; on the other, the definition plus a memory hook. For ‘catalyst’, the hook could be ‘speeds up reaction, remains unchanged’. For ‘reflex arc’, draw a simple arc arrow with labels like receptor, sensory neurone, relay neurone, motor neurone, effector.
如果使用得当，闪卡仍然是最有效的工具之一。在一面写上科学术语，在另一面写上定义加上一个记忆钩子。对于 ‘catalyst’（催化剂），钩子可以是 “加速反应，自身不变”。对于 ‘reflex arc’（反射弧），画一个简单的弧线箭头，并标上感受器、感觉神经元、联络神经元、运动神经元、效应器。
Use the Leitner system: cards you get wrong move to a pile that you review more frequently. Combine this with spaced repetition apps like Anki, but always include your own hand-drawn cues. The physical act of writing and sorting strengthens motor memory, creating multiple retrieval paths.
使用莱特纳系统：答错的卡片移到一个需要更频繁复习的堆中。将此法与 Anki 等间隔重复应用结合使用，但一定要包含你自己手绘的提示。书写和分类的身体动作能强化动作记忆，创建多条检索路径。
9. Using Analogies for Abstract Concepts | 用类比理解抽象概念
Abstract vocabulary becomes concrete when anchored to an analogy. Imagine electric current as water flowing through pipes. Voltage is the water pressure, resistance is the pipe’s narrowness, and charge is the amount of water. This instantly clarifies Ohm’s law and circuit behaviour without memorising dry definitions.
当用类比来锚定时，抽象的词汇会变得具体。把电流想象成在管道中流动的水。电压就是水压，电阻是管道的狭窄程度，电荷则是水量。这能瞬间厘清欧姆定律和电路行为，而无需死记硬背枯燥的定义。
For enzyme specificity, use the lock-and-key model: the enzyme is the lock, the substrate is the key. The active site changes shape slightly (induced fit), just like a lock adjusting to a worn key. Write these analogies alongside definitions, and you will find yourself retelling the story in exams rather than struggling to recall exact wording.
对于酶的特异性，使用锁钥模型：酶是锁，底物是钥匙。活性位点会轻微改变形状（诱导契合），就像锁适应一把磨损的钥匙。将这些类比写在定义旁边，你会发现自己在考试中是在复述故事，而不是费力回忆确切的措辞。
10. Practice through Crosswords and Quizzes | 通过填字游戏和测试练习
Turn terminology revision into a puzzle. Design a crossword where clues are functions or definitions and answers are the scientific terms. For example, ‘the site of aerobic respiration (12 letters)’ → mitochondria. Online tools allow you to generate these quickly, but writing your own is even more powerful because it forces you to think from the examiner’s perspective.
将术语复习变成一个谜题。设计一个填字游戏，提示是功能或定义，答案是科学术语。例如，“有氧呼吸的场所（12个字母）”→ mitochondria。在线工具可以快速生成这些，但自己编写则更为强大，因为它迫使你从出题人的角度思考。
Partner with a study buddy for rapid-fire quizzes. One person gives the definition, the other must name the term within three seconds. Switch roles and focus on commonly confused pairs: mitosis vs meiosis, osmosis vs diffusion, endothermic vs exothermic. The pressure of time simulates exam conditions and highlights weak spots instantly.
与学习伙伴一起进行快速问答。一人给出定义，另一人必须在三秒内说出术语。交换角色，并专注于常混淆的词对：有丝分裂与减数分裂、渗透与扩散、吸热与放热。时间压力模拟了考试环境，并能立即暴露薄弱环节。
11. Common Exam Terminology and Command Words | 常见考试术语和指令词
Examiners mark your ability to respond correctly to command words such as describe, explain, state, compare and evaluate. ‘State’ requires a short factual answer. ‘Describe’ needs a detailed account of what is observed or what happens. ‘Explain’ must include a scientific reason or mechanism. Memorise this hierarchy with a colour code: state = red (quick), describe = yellow (details), explain = green (reasons).
考官会考查你对指令词（如描述、解释、陈述、比较和评估）做出正确回应的能力。’State’ 要求简短的客观事实回答。’Describe’ 需要对观察到或发生的情况进行详细描述。’Explain’ 则必须包含科学原因或机制。用颜色编码记住这一层级：陈述 = 红色（快速），描述 = 黄色（细节），解释 = 绿色（理由）。
Highlight command words in past papers and practise structuring responses. For ‘compare’, always use linking words like ‘whereas’ or ‘both’, and refer to specific properties. Understanding what each term demands means you stop losing marks by writing the right content in the wrong form.
在历年真题中高亮指令词，并练习构建回答结构。对于 ‘compare’（比较），始终使用 ‘whereas’（而）或 ‘both’（两者都）等连接词，并提及具体的特性。理解每个术语的要求意味着你不会再因为用错误的形式写对内容而丢分。
12. Final Tips: The Feynman Technique | 终极技巧：费曼学习法
The Feynman Technique is a perfect test of whether you truly understand a term. Pick a concept like ‘natural selection’, and try to explain it in simple language as if teaching a younger sibling. If you stumble or use jargon without unpacking it, that reveals a gap. Go back to your notes, fill the gap, and try again until the explanation flows smoothly.
费曼学习法是检验你是否真正理解一个术语的完美方法。选择一个如“自然选择”的概念，并尝试用简单的语言解释，就像在教一个年幼的弟弟妹妹。如果你卡住了，或者用了未加以解释的术语，那就揭示了一个漏洞。回到笔记，填补漏洞，然后再试一次，直到解释流畅为止。
Combine this with interleaved practice: mix terms from Biology, Chemistry and Physics in the same revision session. This prevents your brain from relying on topic context and forces true recall. Write a brief summary for each term using the ‘define, exemplify, connect’ pattern: define it, give an example, and link it to another topic. This holistic approach prepares you for synoptic questions that span the entire CAIE Science syllabus.
将此与交叉练习相结合：在同一次复习中混合生物、化学和物理的术语。这能防止你的大脑依赖主题背景，并迫使你进行真正的回忆。对每个术语使用“定义、举例、联系”模式写一个简短总结：定义它，举个例子，并联系到另一个主题。这种整体方法能为你应对横跨整个 CAIE 科学大纲的综合性问题做好准备。
