1. Measurement, Units and Prefixes | 测量、单位与前缀
SI Prefixes: Prefixes modify base units: milli (m, 10⁻³), micro (μ, 10⁻⁶), nano (n, 10⁻⁹), pico (p, 10⁻¹²). To recall descaling order, use ‘My Micro Nana Picks’ apples, imagining a small grandmother choosing tiny fruit.
国际单位制前缀：前缀修饰基本单位：毫 (m, 10⁻³)、微 (μ, 10⁻⁶)、纳 (n, 10⁻⁹)、皮 (p, 10⁻¹²)。记忆递减顺序可想象 ‘毫微纳皮’ 像人名，或记住 ‘微小纳皮’ 越来越小。
Accuracy vs Precision: Accuracy describes how close a result is to the true value; precision describes the spread of repeated measurements. Think of accuracy as hitting the bull’s-eye, precision as grouping tightly anywhere on the target.
准确度与精密度：准确度表示结果与真实值的接近程度；精密度指重复测量值的离散程度。可将准确度想象为命中靶心，精密度为弹着点集中（但未必在靶心）。
Systematic vs Random Error: A systematic error shifts all readings in one direction (zero error), while random errors scatter results unpredictably. Visualise systematic error as a crooked ruler, random as shaky hands.
系统误差与随机误差：系统误差使所有读数偏向一方向（如零误差），随机误差则使结果不可预测地散开。想象系统误差像一把歪斜的尺子，随机误差像颤抖的手。
2. Atomic Structure and Particles | 原子结构与粒子
Atom, Element and Compound: An atom is the smallest particle of an element; an element contains only one type of atom; a compound has two or more elements chemically bonded. Remember ‘Elements are like single letters, compounds are words.’
原子、元素与化合物：原子是元素的最小粒子；元素仅由一种原子构成；化合物由两种或以上的元素化学键合而成。可记住 ‘元素如同单个字母，化合物是单词’。
Proton, Neutron, Electron: Protons (positive, in nucleus), neutrons (neutral, in nucleus), electrons (negative, orbiting in shells). Use ‘P-N-E’ order: Proton in nucleus, Neutron also nucleus, Electron outside. Think ‘Protons are Positive, Neutrons are Neutral’.
质子、中子、电子：质子（正电，在核内）、中子（中性，在核内）、电子（负电，在核外壳层中）。可记忆 ‘质子正，中子在核’，电子在外部轨道。
Isotope: Isotopes are atoms of the same element with the same atomic number (Z) but different mass numbers (A). The root ‘iso’ means same, ‘topos’ place – same place in the periodic table. Visualise twins with different weights.
同位素：同位素是同一元素中质子数相同而质量数不同的原子。词根 ‘iso’ 意为相同，’topos’ 意为位置——在周期表中同一位置。可想象为体重不同的双胞胎。
3. Chemical Bonding and Formulae | 化学键与化学式
Ionic Bonding: Transfer of electrons from a metal to a non-metal, forming oppositely charged ions that attract. Remember ‘Ionic = I Own a charge’. NaCl: Na⁺ Cl⁻.
离子键：金属向非金属转移电子，形成带相反电荷的离子并相互吸引。可记为 ‘离子键——离（电）子成键’。NaCl：Na⁺ Cl⁻。
Covalent Bonding: Sharing of electron pairs between non-metal atoms. Think ‘co-‘ meaning together, ‘valent’ relating to valence electrons. H₂O shares electrons so each H gets 2, O gets 8.
共价键：非金属原子之间共用电子对。’co-‘ 意为共同，’valent’ 涉及价电子。水分子中，共用电子使氢达到2电子的稳定结构。
The Mole and Avogadro Constant: One mole contains 6.02×10²³ particles. Remember ‘A mole is like a chemist’s dozen’. Avogadro’s number is huge: if each particle were a penny, you’d bury Earth in coins.
摩尔与阿伏伽德罗常数：1 摩尔含有 6.02×10²³ 个粒子。记住 ‘摩尔如同化学中的打’。阿伏伽德罗数极大：若每个粒子为一便士，足以将地球掩埋在硬币中。
Empirical vs Molecular Formula: Empirical formula gives the simplest whole-number ratio of atoms; molecular formula shows the actual number. Glucose: CH₂O (empirical), C₆H₁₂O₆ (molecular). Visualise simplifying a fraction.
经验式与分子式：经验式表示原子数的最简整数比；分子式显示实际原子数。葡萄糖经验式 CH₂O，分子式 C₆H₁₂O₆。可想象为约分。
4. Cell Biology Essentials | 细胞生物学基础
Eukaryotic vs Prokaryotic: Eukaryotic cells have a membrane-bound nucleus (‘eu’ = true, ‘karyon’ = nut/kernel); prokaryotic cells lack a nucleus (‘pro’ = before). Remember: EUkaryotes have true nUcleus.
真核与原核：真核细胞有膜包被的细胞核（’eu’ 真，’karyon’ 核）；原核细胞无细胞核（’pro’ 前）。联想：真核=真有核。
Organelle: Specialised subunit within a cell that has a specific function. Think of organelles as ‘tiny organs’ of the cell. Mitochondria are the powerhouse – remember ‘mighty’ mitochondria.
细胞器：细胞内具有特定功能的特化亚单位。可将细胞器想象为细胞的 ‘小器官’。线粒体是动力工厂——可记 ‘线粒体提供能量’。
Diffusion, Osmosis, Active Transport: Diffusion is net movement of particles from high to low concentration. Osmosis is diffusion of water molecules through a partially permeable membrane. Active transport moves substances against the concentration gradient using energy. Remember ‘Diffusion = Downhill, Active = Uphill (needs energy).’
扩散、渗透与主动运输：扩散是粒子从高浓度向低浓度的净移动。渗透是水分子通过半透膜的扩散。主动运输逆浓度梯度使用能量运输物质。记牢 ‘扩散如下坡，主动如上坡需能量’。
5. Genetics and Inheritance | 遗传与继承
Gene and Allele: A gene is a section of DNA coding for a protein; an allele is a variant form of a gene. Think of a gene as a recipe, and alleles as different versions (e.g., vanilla or chocolate).
基因与等位基因：基因是编码蛋白质的 DNA 片段；等位基因是基因的变体形式。将基因比作食谱，等位基因就是不同口味（香草味或巧克力味）。
Dominant vs Recessive: Dominant alleles are expressed even if only one copy is present; recessive alleles require two copies. Use capital letter (A) for dominant, lowercase (a) for recessive – ‘A’ is assertive, ‘a’ is shy.
显性与隐性：显性等位基因只需一个拷贝即可表达；隐性等位基因需要两个拷贝。用大写字母 (A) 表示显性，小写 (a) 表示隐性——A 自信，a 害羞。
Homozygous vs Heterozygous: Homozygous means having two identical alleles (AA or aa); heterozygous means two different alleles (Aa). ‘Homo’ = same, ‘hetero’ = different. Remember ‘Homozygous = homogenous mixture.’
纯合与杂合：纯合指两个等位基因相同 (AA 或 aa)；杂合指两个不同 (Aa)。’Homo’ 同，’hetero’ 异。可联想 ‘纯合如纯一’。
6. Forces and Motion | 力与运动
Scalar and Vector: Scalars have magnitude only (e.g., speed, distance, mass); vectors have magnitude and direction (e.g., velocity, displacement, force). Vectors often have arrows; visualise ‘V for Vector, V for direction arrow.’
标量与矢量：标量仅有大小（如速率、路程、质量）；矢量有大小和方向（如速度、位移、力）。矢量常带箭头；联想 ‘矢（shǐ）量方向箭’。
Displacement vs Distance: Distance is the total path length (scalar); displacement is the straight-line change in position (vector). If you run a lap and return to start, distance is 400 m, displacement is zero.
位移与路程：路程是路径总长度（标量）；位移是位置变化（矢量）。跑一圈回到起点，路程400米，位移为零。
Newton’s Second Law: F = ma, resultant force equals mass times acceleration. Remember ‘Force makes mass accelerate’. For a fixed mass, more force means more acceleration.
牛顿第二定律：F = ma，合力等于质量乘加速度。记牢 ‘力使质量加速’。质量一定时，力越大加速度越大。
7. Waves and Their Properties | 波及其性质
Transverse and Longitudinal Waves: In transverse waves, oscillations are perpendicular to energy transfer (e.g., light, water ripples). In longitudinal waves, oscillations are parallel (e.g., sound). To remember: ‘Transverse = up-and-down, Longitudinal = push-and-pull along.’
横波与纵波：横波中振动垂直于能量传递方向（如光、水波）；纵波中振动平行于传递方向（如声）。记忆：横波上下，纵波前后推拉。
Wavelength (λ), Frequency (f), Amplitude: Wavelength is the distance between consecutive crests; frequency is the number of waves per second (Hz). Amplitude is the maximum displacement from rest. Equation: v = fλ. Think of ‘Very Fast Lamborghini’.
波长 (λ)、频率 (f)、振幅：波长是相邻波峰间的距离；频率是每秒波数 (Hz)。振幅是离开平衡位置的最大位移。公式 v = fλ，可联想 ‘速度=频率乘波长’。
Refraction: Bending of waves when they cross a boundary between media of different densities, due to speed change. Use ‘FST’ – Faster, Shallow angle, Towards normal? Actually, ‘From fast to slow, bends towards normal’. Visualise a car driving from tarmac to mud – it slows and turns.
折射：波穿过不同密度介质界面时因速度改变而弯曲。从快介质到慢介质，波向法线弯曲。想象汽车从公路驶入泥地会减速并偏转。
8. Electricity and Circuits | 电与电路
Current (I), Potential Difference (V), Resistance (R): Current is the rate of flow of charge; p.d. is energy transferred per unit charge; resistance opposes current. Ohm’s Law: V = IR. Remember ‘Victory Is Resistance times current’.
电流、电势差与电阻：电流是电荷流动的速率；电势差是单位电荷转移的能量；电阻阻碍电流。欧姆定律 V = IR。可记 ‘V = 电流×电阻’。
Series and Parallel Circuits: In series, current is the same everywhere, voltage splits. In parallel, voltage is the same across branches, current splits. Think ‘Series – one path; Parallel – many paths’.
串联与并联电路：串联时电流处处相等，电压分摊；并联时各支路电压相等，电流分流。串联如单行道，并联如多车道。
Power: P = IV (power = current × voltage). Using substitution, P = I²R or P = V²/R. ‘Power hungry’ appliances need high current or voltage.
功率：P = IV（功率=电流×电压）。代入可得 P = I²R 或 P = V²/R。高功率电器需大电流或高电压。
9. Energy and Reactions | 能量与反应
Kinetic Energy and Gravitational Potential Energy: KE = ½mv², GPE = mgh. Kinetic energy depends on speed squared – doubling speed quadruples KE. GPE is stored energy due to position in a gravitational field. Remember ‘GPE = mgh, like “mighty great height”.’
动能与重力势能：动能 = ½mv²，重力势能 = mgh。动能与速度平方成正比——速度翻倍则动能增至四倍。重力势能是因位置而储存的能量。可记 ‘GPE = mgh，类似 “mgh”‘。
Endothermic and Exothermic: Endothermic reactions absorb heat (ΔH > 0); exothermic release heat (ΔH < 0). 'Exo' = exit, 'endo' = enter. Combustion is exothermic; photosynthesis is endothermic. Visualise heat leaving or entering.
吸热与放热：吸热反应吸收热量 (ΔH > 0)；放热反应释放热量 (ΔH < 0)。'Exo' 外出，'endo' 进入。燃烧放热，光合作用吸热。想象热量进出。
Activation Energy (Eₐ): Minimum energy colliding particles must have for a reaction to occur. Think of it as the ‘hill’ molecules must climb. Catalysts lower Eₐ, making the hill smaller.
活化能 (Eₐ)：反应物分子发生碰撞反应所需的最小能量。想象为分子必须翻越的山丘。催化剂降低活化能，使山丘变矮。
10. Ecology and Fieldwork | 生态学与野外调查
Population, Community, Ecosystem: A population is all organisms of one species in a habitat; a community is all populations interacting; an ecosystem includes the community and abiotic factors. Remember ‘Populations make up Communities, which live in Ecosystems.’
种群、群落、生态系统：种群是同一栖地中同一物种的所有个体；群落是所有相互作用的种群；生态系统包括群落和非生物因子。可记 ‘种群组成群落，群落生活在生态系统中’。
Habitat and Niche: A habitat is where an organism lives (its ‘address’); a niche describes its role and how it fits in (its ‘profession’). For a barnacle, the rock face is its habitat, filtering plankton is part of its niche.
栖息地与生态位：栖息地是生物生活的地方（’住址’）；生态位描述其角色与适应方式（’职业’）。藤壶的栖息地是岩石表面，滤食浮游生物属于其生态位。
Biodiversity: The variety of life – measured by species richness and evenness. High biodiversity indicates a healthy ecosystem. Memory aid: ‘Bio-diversity = diversity of life forms’, like a mixed fruit salad vs a bowl of only apples.
生物多样性：生命的多样性——用物种丰富度和均匀度衡量。高生物多样性表明生态系统健康。记忆法：’生物多样性’ 如什锦水果沙拉对比单种苹果。
