Mastering scientific terminology is the gateway to success in Year 11 CAIE Science. Across Biology, Chemistry and Physics, you encounter hundreds of specialised words that can feel overwhelming. This guide distils proven memorisation strategies into ten practical steps, helping you move from rote repetition to deep, lasting understanding. By adopting these techniques, you will read questions more fluently, write precise answers and approach your exams with greater confidence.
掌握科学术语是通往 Year 11 CAIE 科学成功的门户。在生物、化学和物理学科中，你会遇到数百个专业词汇，令人应接不暇。本指南将经过验证的记忆策略浓缩为十个实用步骤，帮助你从死记硬背走向深层次、持久的理解。运用这些技巧，你将更流畅地阅读题目，写出准确的答案，并以更强的信心迎接考试。
1. Why Terminology Decides Your Grade | 为什么术语决定你的分数
In CAIE Biology, Chemistry and Physics, marks are awarded for precise vocabulary rather than for vague ideas. A question that asks you to define diffusion expects 'the net movement of particles from a region of higher concentration to a region of lower concentration, down a concentration gradient'. A loose paraphrase such as 'particles spreading out' may score nothing at all.
在 CAIE 生物、化学和物理考试中，得分取决于精确的词汇，而不是模糊的想法。一道要求你定义扩散的题目，期待的是 "粒子从高浓度区域向低浓度区域的净移动，沿浓度梯度进行"。像 "粒子散开" 这样松散的解释可能一分都拿不到。
Terminology also controls your reading speed. If you must decode every third word, you lose time and misread the command word hidden in the question. Fluent recognition of terms such as exothermic, refraction and osmosis lets you spend your thinking time on the science, not on translation.
术语还决定你的阅读速度。如果每三个词就要解码一次，你会浪费时间，并误读题干中隐藏的指令词。对流利识别 exothermic（放热的）、refraction（折射）和 osmosis（渗透）等术语，能让你把思考时间花在科学本身，而不是翻译上。
- Precision mark: the exact term earns the mark. | 精准分：用对术语才得分。
- Time mark: fast recognition saves minutes per paper. | 时间分：快速识别每份卷子省下数分钟。
- Confidence mark: familiar language reduces exam panic. | 信心分：熟悉的语言降低考试恐慌。
2. The Power of Word Roots in Biology | 生物学词根的力量
Many intimidating biological terms are built from a handful of Greek and Latin roots. Once you spot these building blocks, you can decode meanings without memorising every word independently. For instance, 'photo-' means light and '-synthesis' means putting together, so 'photosynthesis' literally means 'putting together with light'. Similarly, 'hydro-' refers to water, giving us 'hydrolysis' - splitting by water. The prefix 'a-' or 'an-' signals 'without', as in 'anaerobic' (without air) and 'asexual' (without sex).
许多令人生畏的生物学术语源自少数希腊语和拉丁语词根。一旦你认出这些构建模块，就无需单独记忆每个单词，便能解读其含义。例如，'photo-' 意为光，'-synthesis' 意为组合，因此 'photosynthesis' 字面意思就是 "用光组合在一起"。同样地，'hydro-' 指水，衍生出 'hydrolysis'——由水分解。前缀 'a-' 或 'an-' 表示 "没有"，如 'anaerobic'（无空气的）和 'asexual'（无性的）。
Another powerful root is 'cyto-' (cell), seen in 'cytoplasm' (cell substance) and 'cytokinesis' (cell division). The suffix '-troph' means feeding or nourishment, which gives us 'autotroph' (self-feeding, such as a green plant) and 'heterotroph' (feeding on others, such as a mammal). Learn one root and you unlock a whole family of words.
另一个强大的词根是 'cyto-'（细胞），见于 'cytoplasm'（细胞质）和 'cytokinesis'（细胞质分裂）。后缀 '-troph' 表示摄食或营养，由此得到 'autotroph'（自养的，如绿色植物）和 'heterotroph'（异养的，如哺乳动物）。学会一个词根，就打开了一整个词族。
| Root / Affix | Meaning | Example |
| photo- | light | photosynthesis |
| hydro- | water | hydrolysis |
| cyto- | cell | cytoplasm |
| a- / an- | without | anaerobic, asexual |
| -lysis | splitting | hydrolysis |
| -troph | feeding | autotroph |
| chloro- | green | chloroplast |
| therm- | heat | thermoregulation |
3. Chemistry: Prefixes, Suffixes and Systematic Naming | 化学：前缀、后缀与系统命名
Chemistry rewards anyone who reads a name as an instruction. The prefixes mono-, di-, tri- and tetra- tell you how many atoms are present, so carbon dioxide contains one carbon and two oxygens, while sulfur trioxide contains one sulfur and three oxygens. Endings carry meaning too: '-ide' usually means a compound of two elements, '-ate' and '-ite' indicate oxygen-containing ions, and '-ous' and '-ic' appear in older names such as iron(II) and iron(III) compounds.
化学奖励那些把名称当作说明书来读的人。前缀 mono-、di-、tri- 和 tetra- 告诉你原子的数量，因此 carbon dioxide（二氧化碳）含一个碳和两个氧，而 sulfur trioxide（三氧化硫）含一个硫和三个氧。词尾同样有意义：'-ide' 通常指两种元素组成的化合物，'-ate' 和 '-ite' 表示含氧离子，而 '-ous' 和 '-ic' 出现在铁(II)、铁(III) 等较旧的命名中。
Process words are equally systematic. '-lysis' means splitting, so electrolysis is splitting with electricity. Oxidation is loss of electrons and reduction is gain of electrons, remembered as 'OIL RIG'. Exothermic means heat is given out and endothermic means heat is taken in, so the prefix tells you the direction of energy transfer before you even read the numbers.
过程类词汇同样有规律。'-lysis' 意为分解，因此 electrolysis（电解）就是用电分解。氧化是失去电子，还原是得到电子，可用 'OIL RIG' 记忆（Oxidation Is Loss, Reduction Is Gain）。Exothermic 表示放热，endothermic 表示吸热，前缀在你读到数据之前就已经告诉你能量传递的方向。
2H₂O → 2H₂ + O₂ | CH₄ + 2O₂ → CO₂ + 2H₂O
4. Physics: Quantities, Units and Definition Vocabulary | 物理：物理量、单位与定义词汇
Physics marks are frequently lost through confused quantities rather than confused mathematics. Mass is the amount of matter in kilograms, while weight is the gravitational force on that mass in newtons. Speed is a scalar, velocity is a vector, distance is how far you travelled and displacement is how far you are from the start. Learn the pairs, not the single words.
物理失分往往源于混淆物理量，而不是算错数学。质量是物体所含物质的多少，单位是千克；而重力是作用在该质量上的引力，单位是牛顿。速率是标量，速度是矢量；路程是你走了多远，位移是你离起点多远。要成对记忆，而不是记单个词。
Unit symbols are part of the vocabulary and must be written correctly: kg, m, s, A, V, Ω, J, W, N, Pa, Hz, °C and K. Capital letters matter, because m means metres while M may be misread, and s means seconds while S is siemens. Attach the correct unit to every calculated answer or you will drop an otherwise earned mark.
单位符号也是词汇的一部分，必须书写正确：kg、m、s、A、V、Ω、J、W、N、Pa、Hz、°C 和 K。大小写很重要，因为 m 表示米，而 s 表示秒。每一个计算答案都要带上正确的单位，否则会丢掉本可到手的分数。
v = f × λ F = m × a P = V × I Q = m × c × Δθ
5. The Ten-Step Quick-Memorisation System at a Glance | 十步速记体系一览
Everything that follows is built on ten steps that work together. Read the table first, then study each pair of steps in the sections below. The order matters: understanding comes before repetition, and retrieval comes before revision notes.
接下来的一切都建立在相互配合的十个步骤之上。先读这张表，再逐节学习下面成对的步骤。顺序很重要：理解先于重复，提取先于复习笔记。
| Step | Technique | 中文 |
| 1 | Chunk terms into themes | 按主题分块 |
| 2 | Space the repetition | 间隔重复 |
| 3 | Dual code with diagrams | 图文双重编码 |
| 4 | Map connections | 绘制思维导图 |
| 5 | Say definitions aloud | 大声朗读定义 |
| 6 | Teach it back | 反向讲授 |
| 7 | Learn command words | 掌握指令词 |
| 8 | Write precise answers | 精准书写答案 |
| 9 | Retrieve from past papers | 真题提取练习 |
| 10 | Log every error | 记录每一处错误 |
6. Steps 1-2: Chunking and Spaced Repetition | 步骤 1-2：分块与间隔重复
Step 1 is chunking. Do not memorise an alphabetical list of three hundred words. Group six or seven terms that belong to the same topic, such as transpiration, translocation, xylem, phloem, stomata, guard cells and root hair cell. Terms learned inside a story about transport are recalled far more reliably than terms learned in isolation.
第一步是分块。不要去背一张按字母排列的三百词清单。把属于同一主题的六到七个术语归为一组，例如 transpiration（蒸腾作用）、translocation（运输作用）、xylem（木质部）、phloem（韧皮部）、stomata（气孔）、guard cells（保卫细胞）和 root hair cell（根毛细胞）。在有关运输的故事中学会的术语，比孤立记忆的术语更容易被回忆起来。
Step 2 is spacing. Repeating a word ten times tonight feels productive but fades within days. Short reviews spread across weeks build durable memory. Use the schedule below and keep each review under ten minutes.
第二步是间隔。今晚把单词重复十遍感觉很有成效，但几天后就遗忘了。分散在数周内的短时复习才能建立持久记忆。使用下表安排复习，每次控制在十分钟以内。
| Review | When | Task |
| 1 | Day 1 | Learn 7 new terms |
| 2 | Day 2 | Cover and recall |
| 3 | Day 4 | Write definitions from memory |
| 4 | Day 8 | Use terms in sentences |
| 5 | Day 21 | Answer exam questions |
7. Steps 3-4: Dual Coding and Mind Maps | 步骤 3-4：双重编码与思维导图
Step 3 is dual coding, which simply means pairing the word with a picture. Label a diagram of the heart while you recite ventricle, atrium, valve and septum. Draw the lock-and-key model next to the words enzyme, substrate, active site and denaturation. Your brain stores the image and the word in two places, so recalling one triggers the other.
第三步是双重编码，也就是把单词和图像配对。一边背诵 ventricle（心室）、atrium（心房）、valve（瓣膜）和 septum（隔膜），一边标注心脏结构图。在 enzyme（酶）、substrate（底物）、active site（活性位点）和 denaturation（变性）旁边画出锁钥模型。大脑会把图像和单词存放在两个位置，因此回忆其中一个就会触发另一个。
Step 4 builds links between terms. A mind map forces you to decide how ideas relate: current flows through a resistor, potential difference drives it, resistance opposes it. Put one or two words on each branch, use colour for different topics, and redraw the map from memory a week later. Redrawing is the active part that actually fixes the vocabulary.
第四步在术语之间建立联系。思维导图迫使你判断概念之间的关系：电流流过电阻，电压驱使电流，电阻阻碍电流。每条分支只写一到两个词，用颜色区分不同主题，一周后凭记忆重画这张图。重画才是真正巩固词汇的主动环节。
8. Steps 5-6: Say It Aloud and Teach It Back | 步骤 5-6：大声朗读与反向讲授
Step 5 is speaking. Scientific vocabulary is written far more often than it is spoken, so many students recognise a term silently but cannot produce it. Read every full definition aloud, including the qualifiers: 'by a partially permeable membrane', 'in the presence of light', 'per unit time'. Your mouth teaches your memory.
第五步是口头表达。科学词汇被写出来的频率远高于被说出来的频率，所以很多学生能默读认出一个术语，却无法主动产出。把每条完整定义朗读出来，包括限定语：'通过半透膜'、'在有光条件下'、'每单位时间'。嘴巴会教会你的记忆。
Step 6 is teaching it back. Explain oxidation to a friend, a younger sibling or an empty chair as if they know nothing. The moment you hesitate is the moment you discover the gap. This is the fastest way to find out whether you truly know the difference between breathing and respiration, or between heat and temperature.
第六步是反向讲授。把氧化讲给朋友、弟弟妹妹或一张空椅子听，就像他们一无所知。你犹豫的那一刻，就是你发现知识漏洞的那一刻。这也是检验你是否真正分清 breathing（呼吸动作）与 respiration（呼吸作用）、heat（热量）与 temperature（温度）最快的方法。
9. Steps 7-8: Command Words and Precision Writing | 步骤 7-8：指令词与精准作答
Step 7 is decoding the command word before writing anything. 'State' needs one short sentence, 'describe' needs what happens, 'explain' needs why it happens using a scientific reason
