1. Mastering Biology Vocabulary through Roots and Analogies | 通过词根和类比掌握生物学术语
Biology is packed with terms of Greek and Latin origin. Recognising common roots like 'cyto-' (cell), '-plasm' (moulded substance) and '-osis' (process or condition) unlocks a large chunk of the syllabus. Pairing root analysis with vivid mental images makes recall effortless.
生物学术语大多源自希腊语和拉丁语。识别常见词根，如 'cyto-'（细胞）、'-plasm'（可塑之物）和 '-osis'（过程或状态），能帮你轻松掌握大量课纲内容。将词根分析与生动的心理图像结合，可以让记忆毫不费力。
Cytoplasm — 'cyto-' (cell) + '-plasm' (something moulded). It is the jelly-like fluid inside a cell that suspends organelles and is the site of many metabolic reactions.
Cytoplasm（细胞质）—— 'cyto-'（细胞）+ '-plasm'（可塑之物）。它是细胞内部的果冻状液体，承载细胞器，也是许多代谢反应发生的场所。
Memory tip: Picture a transparent 'cell jelly' filling a plastic bag (the cell membrane), with small fruits (organelles) floating inside. The jelly itself is the cytoplasm.
记忆技巧：想象一种透明的“细胞果冻”装满一个塑料袋（细胞膜），里面漂浮着各种小水果（细胞器）。这整袋果冻就是细胞质。
Osmosis — from the Greek 'osmos' meaning push. It is the net movement of water molecules through a partially permeable membrane from a region of higher water potential to a region of lower water potential.
Osmosis（渗透）——源自希腊语 'osmos'，意为推动。指水分子通过半透膜从水势较高的区域向水势较低的区域的净移动。
Memory tip: Think 'water goes where the solute is' — water moves to dilute the more concentrated side. 'Osmosis' sounds like 'slow-mosis', imagining water slowly creeping across the membrane.
记忆技巧：记住“水流向溶质多的地方”——水会去稀释浓度较高的一侧。'Osmosis' 读起来像“slow-mosis”，想象水慢慢爬过半透膜。
2. Key Terms in Cells and Organisation | 细胞与组织层次关键术语
Understanding the hierarchy from cell to organism is fundamental. Terms such as organelle, tissue, organ and organ system often appear in exam questions that ask you to describe structural organisation.
理解从细胞到生物体的层次结构是基础。organelle（细胞器）、tissue（组织）、organ（器官）和 organ system（器官系统）这些术语经常出现在考查结构组织的试题中。
Cell membrane — the partially permeable barrier surrounding every cell, controlling the movement of substances in and out. It is composed of a phospholipid bilayer with embedded proteins.
Cell membrane（细胞膜）——包围每个细胞的半透性屏障，控制物质的进出。它由磷脂双分子层和嵌入蛋白质组成。
Memory tip: View the membrane as a 'bouncer' at a club — only selected molecules are allowed in or out. 'Phospholipid bilayer' suggests two layers of fat-loving heads and tails.
记忆技巧：把细胞膜想象成俱乐部入口的“保安”——只有特定的分子才被允许进出。'Phospholipid bilayer' 提示有两层亲脂的头部和尾部。
Organ system — a group of organs that work together to perform a major function. Examples include the digestive system (mouth, oesophagus, stomach, intestines) and the respiratory system (trachea, lungs, diaphragm).
Organ system（器官系统）——一组协同执行重要功能的器官。例如消化系统（口腔、食道、胃、肠）和呼吸系统（气管、肺、膈）。
Memory tip: Build a story: a hamburger (mouth) travels down a slide (oesophagus), gets churned in a bag (stomach), then squeezed through a long tube (intestines). The narrative organ sequence cements the idea of a system.
记忆技巧：编一个故事：一个汉堡（口腔）沿滑梯（食道）滑下，在袋子（胃）里被搅拌，再被挤压通过长长的管子（肠）。叙事性的器官顺序能够强化系统的概念。

记忆技巧：'Iso-' 意为相同，'tope' 源自希腊语 'topos'（位置）——周期表中同一位置。碳‑12 和碳‑14 是同位素；把它们想成“相同元素，不同体重”。
5. Chemical Bonding Vocabulary: Ions, Compounds, and Formulas | 化学键词汇：离子、化合物与化学式
Bonding terminology can appear abstract. Breaking down words like cation, anion, ionic and covalent through simple stories makes them stick.
化学键术语可能显得抽象。通过简单的故事拆解 cation（阳离子）、anion（阴离子）、ionic（离子键）和 covalent（共价键）等词汇，能让它们记得更牢。
Cation (e.g. Na⁺) — a positively charged ion formed when an atom loses electrons. Metals typically form cations.
Cation（阳离子，如 Na⁺）——原子失去电子后形成的带正电的离子。金属通常形成阳离子。
Memory tip: 'Cation' looks like 'cat-ion'. Cats have paws (positive), so a cation is positive. Or remember 'ca+ion' — the '+' sign hints at its charge.
记忆技巧：'Cation' 有点像 'cat-ion'。猫有爪子（paws 与 positive 谐音），所以 cation 带正电。或者记 'ca+ion'，其中的 '+' 暗示它是正离子。
Anion (e.g. Cl⁻) — a negatively charged ion formed when an atom gains electrons. Non‑metals often form anions.
Anion（阴离子，如 Cl⁻）——原子得到电子后形成的带负电的离子。非金属通常形成阴离子。

记忆技巧：摩尔质量就是“每摩尔的克数”。查看周期表上的原子量——以克为单位时，那个数值就是该元素的摩尔质量。
The key formula: number of moles (n) = mass (m) ÷ molar mass (M). Use the triangle method: cover 'n' to see m ÷ M.
核心公式：物质的量（n）= 质量（m）÷ 摩尔质量（M）。使用三角法：遮住 n，即可见 m ÷ M。
7. Forces and Motion: Directional Terms and Units | 力与运动：方向性术语与单位
In Physics, distinguishing between scalar and vector quantities is crucial. Misusing speed and velocity or distance and displacement can cost marks.

记忆技巧：'Vector' 本身暗示着“箭头”（→）。想象一支飞行的箭：箭的长度表示大小，箭头的指向表示方向。矢量离不开箭头。
Acceleration — the rate of change of velocity, measured in m/s². It is a vector: speeding up, slowing down or changing direction all involve acceleration.
Acceleration（加速度）——速度变化的快慢，单位为 m/s²。它是矢量：加速、减速或改变方向都涉及加速度。
Memory tip: Break it into 'acceler-' (increase speed) + '-ation' on (deceleration) is acceleration. Remember the units m/s² = metres per second per second.
记忆技巧：拆分为 'acceler-'（加速）+ '-ation'（过程）。即使负加速度（减速）也属于加速度。记住单位 m/s²——每秒每秒钟内速度增加的量。
8. Energy Transfers and Resources Keywords | 能量传递与能源关键词
Energy appears in many forms, and the ways it is transferred — conduction, convection, radiation — are frequent exam targets. Linking these terms to everyday situations deepens understanding.
