1. Unlocking Root Words | 解锁词根

Many scientific terms share common Greek or Latin roots. By learning these building blocks, you can often deduce the meaning of an entire term. The table below lists essential roots that appear throughout CCEA Science.

许多科学术语共享常见的希腊语或拉丁语词根。通过学习这些构词成分，你通常可以推断出整个术语的含义。下表列出了CCEA科学中反复出现的必备词根。

Root	Meaning	Example
photo-	light	photosynthesis
-synthesis	putting together	photosynthesis
endo-	inside / within	endothermic
exo-	outside / out	exothermic
therm-	heat	isotherm / thermoregulation
pro-	before / primitive	prokaryote
eu-	true	eukaryote
kary-	nut / nucleus	prokaryote / eukaryote
hydro-	water	hydrolysis / hydrocarbon
-lysis	break down	hydrolysis / electrolysis
electro-	electricity	electrolysis / electrolyte
aero-	air / oxygen	aerobic / anaerobic
an- / a-	without / not	anaerobic / abiotic

For example, “photosynthesis” is formed from “photo-” (light) and “synthesis” (putting together). This immediately tells you it is the process where plants use light energy to build glucose molecules from carbon dioxide and water. Remembering this root pair can help you recall the word’s meaning in an exam even if you momentarily forget the full definition.

例如，”photosynthesis” 由 “photo-“（光）和 “synthesis”（合成）构成。这立刻告诉你，这是一个植物利用光能，由二氧化碳和水构建葡萄糖分子的过程。记住这对词根，即使在考试中暂时忘记完整定义，也能帮你回想起来。

Likewise, “endothermic” (endo- = inside, therm- = heat) refers to reactions that take in heat energy from the surroundings, making the reaction mixture feel colder. “Exothermic” (exo- = outside) means heat is released, warming the surroundings. These roots make it easy to keep the two opposite reaction types straight.

同样，”endothermic”（endo- = 内，therm- = 热）指的是从周围环境吸收热能的反应，使反应混合物变冷。”Exothermic”（exo- = 外）则意味着放出热量，周围变暖。这些词根让你轻松区分这两种相反的反应类型。

When you encounter “prokaryote” and “eukaryote”, notice “kary-” means nucleus. A prokaryote (“pro” = before) lacks a true nucleus, while a eukaryote (“eu” = true) has a membrane-bound nucleus. This single root clarifies a major classification in cell biology.

当你遇到 “prokaryote” 和 “eukaryote” 时，注意 “kary-” 指细胞核。原核生物（”pro” = 前）没有真正的细胞核，而真核生物（”eu” = 真）具有膜包围的细胞核。这一词根阐明了细胞生物学中的一大分类。

2. Turning Terms into Visual Stories | 将术语转化为视觉故事

Our brains remember vivid images far better than abstract words. Assign a mental picture to each key term, and you will strengthen recall dramatically. For “diffusion”, imagine a drop of ink spreading evenly in a glass of water until the whole glass turns light blue. The particles move from a region of high concentration to low concentration, just like the ink spreading until it is uniform.

我们的大脑对生动图像的记忆远胜于抽象文字。为每个关键术语配上一幅心理画面，就能大大增强记忆。对于 “diffusion”（扩散），想象一滴墨水在清水中散开，直到整杯水变淡蓝。微粒从高浓度区域移动到低浓度区域，正如墨水扩散直至均匀。

To remember “osmosis”, picture a semi-permeable membrane as a fishing net that only allows tiny water molecules to pass through, while larger solute particles are trapped. Water moves across the net to dilute the more concentrated side, just as the net “selects” what can pass.

为了记忆 “osmosis”（渗透），想象半透膜就像一张渔网，只允许微小的水分子通过，而较大的溶质颗粒被拦住。水穿过网以稀释浓度更高的一侧，就像网”挑选”了什么能通过。

For “active transport”, visualise a bouncer at a club door – it takes energy (ATP) to push a molecule against the concentration gradient, just like the bouncer forcefully moves someone to the other side. Contrast this with diffusion, where the crowd flows freely without any energy input.

对于 “active transport”（主动运输），想象俱乐部门口的保安——需要能量（ATP）将分子逆着浓度梯度推动，就像保安用力将某人推到另一边。与此对比，扩散则像人群自由流动，无需任何能量输入。

In Physics, “momentum” can be imagined as a heavy shopping trolley rolling downhill – the greater the mass and the faster it moves, the harder it is to stop. This image links directly to the formula p = m × v, making the concept stick.

在物理中，”momentum”（动量）可以想象成一辆沉重的购物车沿着斜坡滑下——质量越大、速度越快，就越难停下。这一图景直接联系到公式 p = m × v，让概念变得深刻。

3. Flashcards with Active Recall | 闪卡主动回忆法

Flashcards are one of the most efficient tools for vocabulary retention, especially when combined with active recall. Write the scientific term on one side and its concise CCEA definition plus Mandarin translation on the other. Test yourself by reading the term and trying to recall the full meaning and an example before flipping the card.

闪卡是记忆词汇最高效的工具之一，结合主动回忆效果更佳。在一面写上科学术语，另一面写简明的CCEA定义及中文翻译。先读术语，努力回想完整含义和例子，然后再翻看答案，以此自测。

Use the Leitner system to space your reviews: cards you get wrong stay in a high-frequency pile, while those you recall easily move to weekly or monthly review. This targets your weak spots without wasting time on already mastered terms.

采用莱特纳间隔复习系统：答错的卡片留在高频复习区，轻松回忆起的卡片则移至每周或每月复习区。这样能针对薄弱环节，不浪费已掌握术语的时间。

For Biology, create a set with terms like “enzyme”, “substrate”, and “active site”. On the back of “enzyme”, write: “A biological catalyst that speeds up a reaction by lowering the activation energy; the active site is complementary to the substrate.” Always include a clear example, such as amylase breaking down starch in the mouth.

对于生物，制作一套卡片，包括 “enzyme”（酶）、”substrate”（底物）和 “active site”（活性位点）。在 “enzyme” 背面写上：”一种生物催化剂，通过降低活化能加速反应；活性位点与底物互补。”务必附上清晰例子，如口腔中淀粉酶分解淀粉。

Chemistry flashcards can include “electrolysis”, “anode”, and “cathode”. Remember to add key equations: at the cathode, reduction occurs (gain of electrons, e.g. Na⁺ + e⁻ → Na). Use the acronym OILRIG (Oxidation Is Loss, Reduction Is Gain) to help you remember which electrode does what.

化学闪卡可包含 “electrolysis”（电解）、”anode”（阳极）和 “cathode”（阴极）。记得添加关键方程式：在阴极发生还原（得到电子，如 Na⁺ + e⁻ → Na）。借助缩写 OILRIG（氧化是失电子，还原是得电子）辅助记忆电极反应。

4. Creating Acronyms and Rhymes | 创造首字母缩写和顺口溜

Acronyms compress a list of related facts into a single memorable word or phrase. For redox reactions, “OILRIG” (Oxidation Is Loss of electrons, Reduction Is Gain of electrons) is a timeless favourite. Every time you see a chemical equation, mentally label whether a species is oxidised or reduced using this cue.

缩写将一系列相关事实压缩成一个易记的单词或短语。对于氧化还原反应，”OILRIG”（氧化是失电子，还原是得电子）是经久不衰的记忆术。每次看到化学方程式，在心里用这个提示标记物质是被氧化还是被还原。

In Biology, the characteristics of living organisms are often taught as “MRS GREN”: Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion, Nutrition. Creating a story with this acronym, such as “Mrs Gren loves all life processes”, makes it stick until the exam hall.

在生物中，生物体的特征常被归纳为 “MRS GREN”：运动、呼吸、感应、生长、繁殖、排泄、营养。用这个缩写编个故事，例如 “Mrs Gren 热爱所有生命过程”，就能牢记至考场。

For the electromagnetic spectrum, “Roman Men Invented Very Unusual X-ray Games” helps recall the order: Radio, Microwave, Infrared, Visible, Ultraviolet, X-ray, Gamma. Adding rhythmic hand-claps while reciting can turn this into a multisensory memory aid.

对于电磁波谱，”Roman Men Invented Very Unusual X-ray Games” 帮助记忆顺序：无线电波、微波、红外线、可见光、紫外线、X射线、伽马射线。一边拍手一边有节奏地背诵，可以把它变成多感官记忆法。

In the electricity topic, remember the difference between series and parallel circuits with a simple rhyme: “In series, current stays the same; in parallel, voltage equals the aim.” While not perfect, catchy phrases like this reduce confusion under pressure.

在电学主题中，用简单韵句记住串联和并联电路的区别：”串联电流处处同，并联电压相等中。”虽然不算完美，但这类朗朗上口的短句能在压力下减少混淆。

5. Grouping Related Concepts | 归类相关概念

Our brain naturally organises information into categories. Grouping CCEA terms by topic creates mental “folders” that make retrieval faster. For cell biology, assemble all organelles – nucleus, mitochondria, ribosome, chloroplast, cell membrane – and learn their functions as a complete set rather than in isolation.

我们的大脑自然会将信息归类。按主题对CCEA术语进行分组，可建立心理”文件夹”，加快提取速度。对于细胞生物学，将所有细胞器——细胞核、线粒体、核糖体、叶绿体、细胞膜——作为一个整体学习其功能，而不是孤立记忆。

Create a classification table for chemical bonds: ionic (transfer of electrons between metal and non-metal, e.g. NaCl), covalent (sharing of electrons between non-metals, e.g. H₂O), and metallic (delocalised electrons in a lattice of positive ions). Under each type, list key properties and at least one real-world example.

创建化学键的分类表：离子键（金属与非金属之间电子转移，如 NaCl）、共价键（非金属之间电子共享，如 H₂O）和金属键（正离子晶格中的离域电子）。在每种类型下列出关键特性和至少一个实例。

In Physics, group energy stores and transfers:
