📚 CIE Year 12 Science: Vocabulary & Terminology Quick Memorisation Guide | CIE 12年级科学：词汇术语速记指南
A strong command of scientific vocabulary is not just about passing exams – it is the tool that turns observations into explanations. For CIE Year 12 students tackling Biology, Chemistry and Physics, the sheer number of new terms can feel overwhelming. This guide breaks down proven strategies to memorise, understand and apply terminology efficiently, helping you speak the language of science with confidence.
牢牢掌握科学词汇不仅仅是为了通过考试，它是将观察转化为解释的工具。对于正在应对生物、化学和物理的 CIE 12 年级学生来说，大量新术语可能让人不知所措。这份指南将拆解行之有效的策略，帮助你高效记忆、理解和运用术语，从而自信地使用科学语言。
1. Why Master Scientific Vocabulary? | 为何要掌握科学词汇？
Command terms such as 'describe', 'explain' and 'evaluate' carry specific meanings in CIE mark schemes. Using precise terminology shows the examiner you understand the underlying concepts, not just memorised facts. A single inaccurate word can cost marks in definitions or structured questions.
在 CIE 评分方案中，“描述”、“解释”和“评价”等指令词具有特定含义。使用精确的术语可以向考官表明你理解了底层概念，而不仅仅是记住事实。一个不准确的词就可能在定义题或结构化问题中丢分。
Beyond exams, scientific vocabulary allows you to read research, follow news and connect ideas across disciplines. Words like 'homeostasis' or 'electronegativity' unlock entire chapters once you internalise them.
在考试之外，科学词汇能让你阅读研究、关注新闻并跨学科联系观点。一旦你内化了“稳态”或“电负性”这样的词，整章知识都会变得清晰。
Building a mental glossary early in Year 12 reduces cognitive load later. Instead of wrestling with language, you can focus on applying principles and solving problems.
在 12 年级早期建立心理词汇库能减轻后续的认知负担。你无需再与语言较劲，而是可以专注于运用原理和解决问题。
2. Decoding Greek and Latin Roots | 破解希腊拉丁词根
Roughly 75% of scientific vocabulary comes from Greek or Latin. Learning a small set of roots gives you the power to guess meanings of unfamiliar terms. For example, 'hydro' (water) + 'philic' (loving) instantly tells you 'hydrophilic' means water-loving.
大约 75% 的科学词汇源于希腊语或拉丁语。学习少量词根，你就能推测陌生术语的含义。例如，“hydro”（水）+ “philic”（喜爱）立刻告诉你“hydrophilic”意为亲水的。
Start by memorising the most frequent prefixes and suffixes across all three sciences. Below is a quick reference table for high-yield roots.
从记忆三科中最常见的前缀和后缀开始。下面是一个高频词根速查表。
| Root | Meaning | Example | 中文 |
|---|---|---|---|
| bio- | life | biology, antibiotic | 生命 |
| therm- | heat | endothermic, thermometer | 热 |
| photo- | light | photosynthesis, photon | 光 |
| electro- | electricity/amber | electrolysis, electrode | 电 |
| mono-/di-/poly- | one/two/many | monomer, dioxide, polymer | 单/双/多 |
| -lysis | splitting | hydrolysis, glycolysis | 分解 |
| -osis | process/condition | mitosis, osmosis | 过程/状态 |
| -ase | enzyme | amylase, polymerase | 酶 |
Create a root map in your notebook. Each time you encounter a new term, break it into root elements and guess the meaning before checking a dictionary. This active analysis cements the word far better than passive reading.
在笔记本中创建词根导图。每次遇到新术语时，先将其分解为词根元素，猜测含义，再查字典核实。这种主动分析比被动阅读更能牢固地记住单词。
3. Biology: Essential Prefixes and Suffixes | 生物：必备前缀与后缀
Biology terminology often describes structures, processes or conditions. Recognising patterns like 'hyper-' (above normal) and 'hypo-' (below normal) helps you distinguish hypertonic from hypotonic solutions instantly.
生物学术语通常描述结构、过程或状态。识别“hyper-”（高于正常）和“hypo-”（低于正常）这样的模式，能让你立刻区分高渗和低渗溶液。
Focus on the organelles: 'nucleus', 'mitochondrion', 'ribosome'. The suffix '-some' means body, while '-elle' indicates small. Thus, an organelle is a 'little organ'. Understanding this makes the abstract concrete.
着重关注细胞器：“nucleus”（细胞核）、“mitochondrion”（线粒体）、“ribosome”（核糖体）。“-some”后缀意为“体”，而“-elle”表示“小”。因此“organelle”就是“小器官”。理解这一点能让抽象变得具体。
For processes, remember 'cyto-' (cell) + 'kinesis' (movement) gives cytokinesis (cell division of cytoplasm). 'Phago-' (eating) + 'cytosis' (cell process) describes phagocytosis. Build a chart grouping terms sharing the same root.
对于过程，记住“cyto-”（细胞）+“kinesis”（运动）= cytokinesis（胞质分裂）。“phago-”（吃）+“cytosis”（细胞过程）描述了吞噬作用。制作一个图表，将共享相同词根的术语分组。
Mnemonic sentences help chain long names: 'King Philip Came Over For Good Soup' for Kingdom, Phylum, Class, Order, Family, Genus, Species. Adapt this to biological classification or respiration steps.
记忆句有助于串联长名称：如“King Philip Came Over For Good Soup”对应界、门、纲、目、科、属、种。将此法调整用于生物分类或呼吸作用步骤。
4. Chemistry: Nomenclature and Symbol Patterns | 化学：命名法与符号规律
CIE Chemistry demands fluency in naming inorganic and organic compounds. Master the suffixes: '-ide' for binary compounds (sodium chloride, NaCl), '-ate' for oxyanions with more oxygen (sulfate, SO₄²⁻), and '-ite' for fewer oxygen atoms (sulfite, SO₃²⁻).
CIE 化学要求流利掌握无机物和有机物的命名。掌握后缀：“-ide”用于二元化合物（氯化钠 NaCl），“-ate”用于含氧较多的酸根（硫酸根 SO₄²⁻），“-ite”用于含氧较少的酸根（亚硫酸根 SO₃²⁻）。
Organic nomenclature follows a logical sequence: prefix (substituents) + root (carbon chain length) + suffix (functional group). For alkanes, meth- (1C), eth- (2C), prop- (3C), but- (4C) are the building blocks. Learn them as a story: 'Mice Eat Peanut Butter'.
有机命名遵循逻辑顺序：前缀（取代基）+词干（碳链长度）+后缀（官能团）。对于烷烃，meth-（1碳）、eth-（2碳）、prop-（3碳）、but-（4碳）是基本单元。用故事记忆：“Mice Eat Peanut Butter”（老鼠吃花生酱）。
Oxidation numbers can be memorised using Roman numerals. For transition metals, iron(II) indicates Fe²⁺. Link this to the phrase 'reduction is gain of electrons', using the mnemonic OIL RIG (Oxidation Is Loss, Reduction Is Gain).
氧化数可用罗马数字记忆。对于过渡金属，iron(II) 表示 Fe²⁺。将其与“还原是得到电子”联系起来，使用助记法 OIL RIG（氧化失电子，还原得电子）。
Balance chemical equations by seeing them as puzzles. Always verify atom counts as a habit. Practice writing equations with proper state symbols (s), (l), (g), (aq) so these become second nature.
通过将化学方程式视为谜题来配平。养成检查原子数的习惯。练习书写带有正确状态符号 (s)、(l)、(g)、(aq) 的方程式，使其成为第二天性。
2H₂(g) + O₂(g) → 2H₂O(l)
5. Physics: Quantities, Units and Symbols | 物理：量、单位与符号
Physics terminology is built on a foundation of base quantities and derived units. Memorise the seven SI base units: metre (m), kilogram (kg), second (s), ampere (A), kelvin (K), mole (mol) and candela (cd). Recognise that all other units derive from these.
物理术语建立在基本量和导出单位的基础之上。记住七个 SI 基本单位：米 (m)、千克 (kg)、秒 (s)、安培 (A)、开尔文 (K)、摩尔 (mol) 和坎德拉 (cd)。要知道所有其他单位都由这些导出。
ce / time has units m/s. If you derive an equation giving m²/s, you know there is an error. This habit reinforces both vocabulary and problem-solving.
使用量纲分析来检查方程式。例如，速度 = 距离/时间，单位为 m/s。如果你推导出的方程给出 m²/s，就知道有错误。这个习惯能同时巩固词汇和解题能力。
Grasp the difference between scalar and vector quantities. Scalars have magnitude only (mass, temperature); vectors have magnitude and direction (velocity, force). Draw arrows to represent vectors and label them consistently.
掌握标量与矢量之间的区别。标量只有大小（质量、温度）；矢量有大小和方向（速度、力）。画出箭头表示矢量，并始终如一地标注它们。
istance. The relationship V = IR becomes a visual chunk. Repeat the definition of current: 'The rate of flow of charge' until it becomes automatic.
在电学中，将符号与物理量联系起来：Q 代表电荷，I 代表电流，V 代表电势差，R 代表电阻。关系式 V = IR 成为一个视觉模块。反复背诵电流的定义：“电荷流动的速率”，直到脱口而出。
I = Q / t and P = IV = I²R
6. Acronyms and Mnemonics for Processes | 过程缩略词与记忆术
Acronyms compress multi-step sequences into memorable chunks. For the reactivity series, 'Please Stop Calling Me A Careless Zebra' stands for Potassium, Sodium, Calcium, Magnesium, Aluminium, Carbon, Zinc. Carbon is included for extraction context.
缩略词将多步骤序列压缩成易记的组块。对于金属活动性顺序，“Please Stop Calling Me A Careless Zebra” 代表钾、钠、钙、镁、铝、碳、锌。碳因提取背景而被包含其中。
In Biology, 'MRS GREN' reminds you of the characteristics of life: Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion, Nutrition. In Chemistry, 'NAP' for acids: Neutralisation, Acid + base, Proton donor.
在生物中，“MRS GREN” 提醒你生命的特征：运动、呼吸、感应、生长、繁殖、排泄、营养。在化学中，“NAP” 代表酸：中和、酸+碱、质子供体。
For physics, 'SUVAT' equations are standard: S (displacement), U (initial velocity), V (final velocity), A (acceleration), T (time). Create a story: 'Silly Unicorns Visit Apple Trees' to recall the symbols. Write each equation on a flashcard with an example.
在物理中，“SUVAT” 方程是标准配置：S（位移）、U（初速度）、V（末速度）、A（加速度）、T（时间）。编一个故事：“Silly Unicorns Visit Apple Trees” 来回忆这些符号。将每个方程写在抽认卡上并附上一个例子。
The key is to make mnemonics absurd, personal or humorous – the brain recalls unusual connections much better than dry lists.
关键在于让记忆术荒诞、个性化或幽默——大脑对不寻常关联的记忆远比枯燥列表牢固。
7. Visual and Spatial Memory Techniques | 视觉与空间记忆法
Transform words into diagrams. For 'enzyme-substrate complex', draw a lock and key. Label 'active site', 'substrate', 'product'. The act of drawing encodes the term both visually and kinaesthetically.
将文字转化为图表。对于“酶-底物复合物”，画一把锁和一把钥匙。标注“活性位点”、“底物”、“产物”。绘图这一行为会从视觉和动觉上对术语进行编码。
Mind maps work wonders for interconnected topics like 'bonding'. Place 'chemical bonding' in the centre, branch out to 'ionic', 'covalent', 'metallic', and from each branch add properties, examples and exceptions. Use colours to group related terms.
思维导图对“化学键”等相互关联的主题有奇效。将“化学键”放在中心，分出“离子键”、“共价键”、“金属键”，再从每个分支添加性质、示例和例外。用颜色将相关术语分组。
The method of loci – placing terms along a familiar route in your imagination – is perfect for remembering classification sequences. Imagine walking through your home, each room containing a term. Biology's taxonomy fits neatly into this spatial journey.
位置记忆法——在想象中将术语放在熟悉的路线沿途——非常适合记忆分类序列。想象穿过你的家，每个房间放一个术语。生物的分类学完美契合这种空间旅程。
Flashcards with an image on one side and the term on the other engage dual coding. For physics, sketch a circuit and label the components; for chemistry, show a reaction profile and annotate activation energy.
一面是图像、另一面是术语的抽认卡能发挥双重编码的作用。物理方面，画出电路并标注元件；化学方面，展示反应曲线并标注活化能。
8. Chunking and Spaced Repetition | 组块与间隔重复
The human working memory can hold only a few items at once. Break long definitions into meaningful chunks. For photosynthesis: (1) light energy absorbed by chlorophyll (2) splits water (3) producing oxygen and hydrogen (4) hydrogen reduces CO₂ to glucose. Each chunk is a mini-flashcard.
人类工作记忆一次仅能容纳少量项目。将长定义分解为有意义的组块。以光合作用为例：（1）叶绿素吸收光能（2）分解水（3）产生氧气和氢（4）氢将 CO₂ 还原为葡萄糖。每个组块都是一张小抽认卡。
Combine chunking with spaced repetition. Review terms after one day, then three days, a week and a month. Use a digital tool like Anki or a physical Leitner box. The algorithm ensures you see difficult terms more often.
将组块与间隔重复相结合。在一天后、三天后、一周后和一个月后复习术语。使用 Anki 等数字工具或实体莱特纳盒。这种算法能确保你更频繁地看到难记的术语。
Write your own glossary organised by topic, not alphabetically. Seeing 'diffusion, osmosis, active transport' together highlights differences and strengthens the network of meaning.
按主题而非字母顺序编写自己的术语表。将“扩散、渗透、主动运输”放在一起，能凸显差异并强化意义网络。
9. Applying Terms in Context | 在情境中应用术语
Passive recognition is dangerous. You must produce terms correctly under exam conditions. After learning a new word, write three original sentences using it. For 'isotope': 'Chlorine-35 and chlorine-37 are isotopes with different neutron numbers.'
被动识别很危险。你必须在考试条件下正确地使用术语。学习新词后，用它造三个原创句子。例如“同位素”：“氯-35 和氯-37 是不同中子数的同位素。”
Explain concepts to a classmate or even an imaginary audience. The Feynman technique forces you to simplify and use precise language. If you stumble, you have found a gap in your vocabulary.
向同学甚至想象中的听众解释概念。费曼学习法会迫使你简化并使用精确的语言。如果你卡壳了，那就找到了词汇上的缺口。
Tackle past paper questions early. Notice how mark schemes phrase answers. Terms like 'random motion of particles' for Brownian motion become templates. Imitate the style until it becomes your own.
尽早接触历年真题。留意评分方案如何措辞。像“粒子的无规则运动”用于布朗运动这类术语会成为模板。模仿这种风格，直到它成为你自己的。
10. Common Confusions and Pitfalls | 常见混淆与陷阱
Some words sound similar but carry very different meanings. Differentiating them early saves marks. The table below highlights high-risk pairs.
有些词听起来相似但含义截然不同。尽早区分它们能保住分数。下表列出了高风险词对。
| Term A | Term B | Key Difference | 中文关键区别 |
|---|---|---|---|
| Accuracy | Precision | Closeness to true value vs. repeatability | 接近真值 vs. 可重复性 |
| Mass | Weight | Amount of matter vs. gravitational force | 物质的量 vs. 重力 |
| Heat | Temperature | Energy transfer vs. measure of average kinetic energy | 能量转移 vs. 平均动能度量 |
| Atom | Ion | Neutral particle vs. charged particle | 中性粒子 vs. 带电粒子 |
| Mitosis | Meiosis | Produces identical diploid cells vs. genetically varied haploid gametes | 产生相同二倍体细胞 vs. 产生遗传多样单倍体配子 |
For language-based traps, watch out for command words. 'State' demands a concise answer, often a definition; 'Explain' requires a mechanism or reason. Circle the command word in every question.
对于语言陷阱，留意指令词。“State”要求简洁的回答，通常是定义；“Explain”要求说明机制或原因。在每个问题中圈出指令词。
11. Practice and Self-Testing Strategies | 练习与自测策略
Self-testing is superior to re-reading. Cover the definition and attempt to recall it aloud. Use a whiteboard to write terms from memory, then check accuracy. This retrieval practice strengthens neural pathways.
自测优于反复阅读。遮住定义，尝试口头回忆。用白板凭记忆写出术语，然后检查准确性。这种检索练习能强化神经通路。
Create quick quizzes with the digital tools you already use. Make a Kahoot set with your classmates focusing on errors. Competition adds motivation and highlights weak areas.
用你已经在使用的数字工具创建快速测验。和同学一起制作 Kahoot 题库，重点关注错误。竞争能增加动力并凸显薄弱环节。
Turn your glossary into audio recordings. Listen while commuting. Hearing the correct pronunciation also aids spelling and recognition during exams.
将术语表录制成音频。在通勤时收听。听到正确的发音也有助于考试时的拼写和识别。
Every week, pick a multi-topic question that forces you to combine terminology from different areas. For example, 'Explain the energy transfers when an athlete runs, referring to respiration and forces.' This mixed practice mimics the real exam.
每周选一道多主题问题，迫使你结合不同领域的术语。例如，“结合呼吸作用和力，解释运动员跑步时的能量转移。”这种混合练习模拟了真实考试。
12. Resources and Final Tips | 资源与最后提示
Build a personal dictionary on your phone using a note-taking app. Tag each entry by subject and topic. Sync it across devices so you can review moments before walking into the exam hall.
使用笔记应用在手机上建立个人词典。按学科和主题为每个条目打上标签。同步到所有设备，以便在进入考场前能复习片刻。
Use the CIE syllabus vocabulary lists as a checklist. Tick off terms only when you can define them in your own words without looking. Never tick if you 'sort of know' – be brutally honest.
以 CIE 考纲词汇表为检查清单。只有当你不用看就能用自己的话定义术语时，才将其勾掉。如果只是“有点知道”，绝不打勾——要对自己残酷诚实。
Remember that consistency beats cramming. Fifteen minutes of daily terminology work is far more effective than a three-hour panic session. Your brain consolidates memories during sleep, so a brief evening review followed by morning recall works surprisingly well.
记住，持续坚持胜过临时突击。每天十五分钟的术语学习远比三小时的恐慌式复习有效。大脑会在睡眠中巩固记忆，因此晚上短暂复习、早晨回忆的效果出奇地好。
Stay curious. When you encounter a
