1. Unlocking Prefixes and Suffixes | 解锁前缀和后缀
Biology words are built from predictable Greek and Latin parts. Decoding them means you can work out meanings even if you have never seen a term before. For example, 'hyper-' means above normal, 'hypo-' means below normal, 'cyto-' refers to cells, 'bio-' to life, the suffix '-ase' signals an enzyme, and '-ose' indicates a sugar.
生物学术语由可预测的希腊语和拉丁语构件组成。破解它们意味着即使你从未见过一个术语，也能推断出意思。例如 'hyper-' 表示高于正常，'hypo-' 表示低于正常，'cyto-' 指细胞，'bio-' 指生命，后缀 '-ase' 代表酶，'-ose' 代表糖类。
Photo- (light) + synthesis ether) = photosynthesis, the process of building glucose using light. Remember: plants use 'light to put together' food.
Photo- (光) + synthesis (合成) = 光合作用，利用光合成葡萄糖的过程。记住：植物'用光合成'食物。
Aero- (air/oxygen) + bic (life) = aerobic, requiring oxygen. An- (without) + aerobic = anaerobic, without oxygen. Link 'an' to 'anti' to recall the opposite.
Aero- (空气/氧气) + bic (生命) = 需氧的。 An- (无) + aerobic = 厌氧的。将 'an' 联想为 'anti' (反) 来记忆相反的含义。
Mono- (one), di- (two), poly- (many) appear in monosaccharide (one sugar unit), disaccharide (two sugars) and polysaccharide (many sugars). Think of 'mono' as 'mono-brow' — single, 'di' as 'divide' into two, 'poly' as 'polygon' with many sides.
Mono- (一), di- (二), poly- (多) 出现于单糖、二糖和多糖中。把 'mono' 想成 '一字眉' — 单一的，'di' 想成 'divide' (分成) 两个，'poly' 想成 '多边形' 有很多边。
2. Cell Structure Terms Made Visual | 细胞结构术语可视化
Draw a simple animal cell and a plant cell, then label organelles while repeating their functions aloud. Connect each organelle to a visual metaphor: the nucleus is the control centre, the cell membrane is a security gate, mitochondria are batteries, ribosomes are protein printers, chloroplasts are solar panels, and the permanent vacuole is a water storage tank.
画一个简单的动物细胞和植物细胞，然后边大声重复功能边标记细胞器。将每个细胞器与一个视觉比喻联系起来：细胞核是控制中心，细胞膜是安检门，线粒体是电池，核糖体是蛋白质打印机，叶绿体是太阳能板，永久液泡是储水罐。
Nucleus — stores genetic material. Memory image: a safe room holding blueprints. Mitochondria (singular: mitochondrion) — site of aerobic respiration. Phrase: 'Mighty mitochondria make energy'.
细胞核 — 储存遗传物质。记忆图像：存放蓝图的安全室。 线粒体 — 有氧呼吸的场所。口诀：'强大的线粒体制造能量'。
Ribosomes — protein synthesis. Tiny dots, like 3D printers building proteins. Chloroplasts — contain chlorophyll, absorb light for photosynthesis. Link 'chloro-' (green) to chlorophyll and chloroplasts: green solar panels.
核糖体 — 蛋白质合成。微小的点，像构建蛋白质的3D打印机。 叶绿体 — 含叶绿素，吸收光进行光合作用。将 'chloro-' (绿) 与叶绿素和叶绿体联系：绿色太阳能板。
Cell wall (plants) — made of cellulose, provides rigid support. Analogy: the plant's skeleton on the outside. Plasmid (bacteria) — small circular DNA loop. Remember 'plasmid' sounds like 'plastic ring' (a small flexible loop).
细胞壁 (植物) — 由纤维素组成，提供刚性支撑。类比：植物外部骨骼。 质粒 (细菌) — 小型环状DNA。把 'plasmid' 联想成 '塑料环' (柔软的小环)。
3. Transport Across Membranes | 跨膜运输术语
Three key processes move substances in and out of cells. Use the 'door, sieve and drinking straw' analogy. Diffusion is like a crowd spreading out through an open door — passive, high to low concentration. Osmosis is a special diffusion for water through a partially permeable membrane, like a sieve allowing only water through. Active transport is like using a drinking straw to pull liquid uphill — it requires energy and moves substances against the concentration gradient.
三个关键过程使物质进出细胞。使用'门、筛子和吸管'的类比。扩散就像人群通过敞开的门散开——被动的、从高浓度到低浓度。渗透是水通过选择性渗透膜的特殊扩散，就像一个只允许水通过的筛子。主动运输就像用吸管把液体往上吸——需要能量，逆浓度梯度移动物质。
Diffusion — net movement of particles from a region of high concentration to a region of low concentration, down a concentration gradient. No energy needed. Example: oxygen diffusing into blood. Osmosis — diffusion of water molecules from a dilute solution to a concentrated solution through a partially permeable membrane. Think 'Osmosis' starts with 'O' like 'Only Water'.
扩散 — 粒子从高浓度区域向低浓度区域的净移动，顺浓度梯度。不需要能量。例子：氧气扩散进入血液。 渗透 — 水分子通过选择性渗透膜从稀溶液向浓溶液的扩散。把 'Osmosis' 的 'O' 想成 'Only Water' (只有水)。
Active transport — movement of molecules or ions against a concentration gradient using energy from respiration. Carrier proteins act like pumps. Link 'active' to 'activity needing energy'. Turgid — a plant cell swollen with water due to osmosis. Think of a 'turgid' crisp lettuce leaf. Plasmolysed — a plant cell that has lost water, membrane pulls away from the wall. Sounds like 'plasma lonely' because the membrane has peeled away.
主动运输 — 利用呼吸作用提供的能量，逆浓度梯度移动分子或离子。载体蛋白像泵一样工作。将 'active' 与 '需要能量的活动' 联系起来。 质壁分离 — 植物细胞失水，细胞膜与细胞壁分离。细胞膜'孤单地'剥离了 (plasma lonely)。 肿胀 — 植物细胞因渗透作用吸水膨胀，像一片脆爽的生菜叶。
4. Biomolecules and Enzymes | 生物分子与酶
Large biological molecules are mostly polymers made of repeating monomers. The four main groups — carbohydrates, lipids, proteins and nucleic acids — each have distinct building blocks. Use food associations to lock them in: carbohydrates are 'sugar chains', proteins are 'meat and repair', lipids are 'long-term energy lockers'.
生物大分子大多是由重复单体组成的聚合物。四大类——碳水化合物、脂质、蛋白质和核酸——各有独特的构件。利用食物联想来锁定：碳水化合物是'糖链'，蛋白质是'肉类和修复'，脂质是'长期能量储物柜'。
Carbohydrates — composed of simple sugars like glucose. Starch and glycogen are storage polysaccharides. Repeating unit: glucose. Proteins — made of amino acids linked by peptide bonds. Enzymes are proteins. Mnemonic: 'Amino acids are the alphabet of proteins'.
碳水化合物 — 由葡萄糖等单糖组成。淀粉和糖原是储存的多糖。重复单元：葡萄糖。 蛋白质 — 由氨基酸通过肽键连接而成。酶是蛋白质。记忆术：'氨基酸是蛋白质的字母'。
Lipids — fats and oils, made of glycerol and three fatty acids. Not polymers but hydrophobic. Enzymes — biological catalysts that speed up reactions without being used up. Each enzyme has an active site complementary to its substrate. The 'lock and key' model is your best visual: the substrate (key) fits the enzyme's active site (lock).
脂质 — 脂肪和油，由甘油和三个脂肪酸组成。不是聚合物，但具疏水性。 酶 — 生物催化剂，加速反应而自身不被消耗。每个酶有一个与底物互补的活性位点。'锁钥模型' 是最佳视觉：底物 (钥匙) 插入酶的活性位点 (锁)。
Denaturation — permanent change to the enzyme's active site shape caused by high temperature or extreme pH, so it can no longer bind its substrate. Imagine unfolding a paper clip so it can't grip paper any more. Optimum — the condition (e.g. temperature, pH) at which an enzyme works fastest.
变性 — 由高温或极端pH引起酶活性位点形状的永久性改变，使其不再能与底物结合。想象把回形针拉直，再也夹不住纸张了。 最适条件 — 酶工作最快时的条件 (如温度、pH)。
5. Photosynthesis and Respiration Equations | 光合作用与呼吸作用方程式
ns is essential. Recite them rhythmically, then test your chemical symbols: Photosynthesis — + water → glucose + oxygen, in the presence of light and chlorophyll. Aerobic respiration — glucose + oxygen → carbon dioxide + water (+ energy released).
这两个过程构成了生命的能量基础。能够写出它们的文字方程式和平衡符号方程式至关重要。有节奏地背诵，然后检验你的化学符号：光合作用——二氧化碳 + 水 → 葡萄糖 + 氧气，需要光和叶绿素。有氧呼吸——葡萄糖 + 氧气 → 二氧化碳 + 水 (+ 释放的能量)。
Photosynthesis: 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂ (light and chlorophyll above the arrow)
光合作用: 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂ (箭头上方标注光和叶绿素)
Aerobic respiration: C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O
有氧呼吸: C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O
Photosynthesis is endothermic – it takes in light energy. Respiration is exothermic – it releases energy. Memorise: 'Photo is making, Respiration is breaking'. Anaerobic respiration in animals produces lactic acid and causes oxygen debt; in yeast it produces ethanol and carbon dioxide (fermentation).
光合作用是吸热的——它吸收光能。呼吸是放热的——它释放能量。记住：'光合是在制造，呼吸是在分解'。动物无氧呼吸产生乳酸并造成氧债；酵母的无氧呼吸产生乙醇和二氧化碳 (发酵)。
Oxygen debt — the extra oxygen required to break down the lactic acid produced during vigorous exercise. Fermentation — anaerobic respiration in microorganisms, economically important for bread and alcohol production.
氧债 — 分解剧烈运动时产生的乳酸所需的额外氧气。 发酵 — 微生物的无氧呼吸，对面包和酒精生产具有重要经济意义。
6. Digestive System and Enzymatic Action | 消化系统与酶作用
small intestine (duodenum and ileum) → large intestine → rectum → anus. Associate each region with its key enzymes and secretions.
消化是将大的不溶性分子分解成可被吸收的小的可溶性分子的过程。沿着路径追踪：口腔 → 食道 → 胃 → 小肠 (十二指肠和回肠) → 大肠 → 直肠 → 肛门。将每个区域与其关键酶和分泌物联系起来。
Amylase — breaks down starch into maltose. Produced in salivary glands and pancreas. Think 'Amyl-ase acts on Amyl-ose (starch)'. Protease — breaks proteins into amino acids. Stomach produces pepsin (a protease). Memory: 'Protease cuts protein like scissors'.
淀粉酶 — 将淀粉分解为麦芽糖。由唾液腺和胰腺分泌。联想：'Amyl-ase 作用于 Amyl-ose (淀粉)'。 蛋白酶 — 将蛋白质分解为氨基酸。胃产生胃蛋白酶 (一种蛋白酶)。记忆：'蛋白酶像剪刀一样剪切蛋白质'。
Lipase — digests lipids into fatty acids and glycerol. Works in the small intestine after bile emulsifies fats. Bile — produced by the liver, stored in the gall bladder, not an enzyme but neutralises stomach acid and emulsifies fats (increases surface area). Visualise bile as washing-up liquid breaking down grease.
脂肪酶 — 将脂质分解为脂肪酸和甘油。在胆汁乳化脂肪后于小肠中工作。 胆汁 — 由肝脏产生，储存在胆囊，不是酶，能中和胃酸并乳化脂肪 (增大表面积)。把胆汁想象为分解油脂的洗涤液。
Villi (singular: villus) — tiny finger-like projections in the small intestine that increase surface area for absorption. They have a rich blood supply and a lacteal for fatty acid absorption. Remember 'villi increase the value (absorption) by reaching out'.
绒毛 — 小肠内微小的指状突起，增大吸收表面积。它们有丰富的血液供应和吸收脂肪酸的乳糜管。记住：'绒毛通过伸展来提高吸收价值'。
7. Circulatory and Respiratory Systems | 循环系统与呼吸系统
The heart is a double pump. Right side pumps deoxygenated blood to the lungs (pulmonary circuit), left side pumps oxygenated blood to the body (systemic circuit). Label the four chambers: right atrium, right ventricle, left atrium, left ventricle. Thickness of left ventricle wall > right because it must pump blood further.
心脏是一个双泵。右侧将缺氧血泵向肺部 (肺循环)，左侧将富氧血泵向全身 (体循环)。标记四个腔室：右心房、右心室、左心房、左心室。左心室壁比右心室厚，因为它要把血液泵送到更远的全身。
Arteries — carry blood away from the heart, thick muscular elastic walls, high pressure. Veins — return blood to the heart, thinner walls, contain valves to prevent backflow. Capillaries — one-cell-thick walls for efficient exchange. Say: 'Arteries Away, Veins have Valves, Capillaries Connect'.
动脉 — 将血液带离心脏，管壁厚而富有肌肉弹性，血压高。 静脉 — 将血液送回心脏，管壁较薄，有静脉瓣防止倒流。 毛细血管 — 单细胞厚的管壁，利于高效交换。口诀：'动脉 Away (离开)，静脉有 Valves (瓣膜)，毛细血管 Connect (连接)'。
Red blood cells — contain haemoglobin to carry oxygen. No nucleus to maximise space. Platelets — cell fragments involved in blood clotting. Phagocytes and lymphocytes are white blood cells; phagocytes engulf pathogens (phagocytosis), lymphocytes produce antibodies. 'Phago-' means eating, like a phagocyte 'eats' germs.
红细胞 — 含血红蛋白运输氧气。无细胞核以最大化空间。 血小板 — 参与血液凝结的细胞碎片。 吞噬细胞 和 淋巴细胞 是白细胞；吞噬细胞吞噬病原体 (吞噬作用)，淋巴细胞产生抗体。'Phago-' 意指进食，吞噬细胞'吃掉'病菌。
In the respiratory system, air flows through: trachea → bronchi → bronchioles → alveoli. Alveoli are adapted for gas exchange: huge surface area, thin walls, moist lining, rich capillary network. Diaphragm and intercostal muscles change thoracic volume for ventilation.
在呼吸系统中，空气流经：气管 → 支气管 → 细支气管 → 肺泡。 肺泡 适应气体交换：巨大表面积、薄壁、湿润内衬、丰富的毛细血管网。 膈肌 和 肋间肌 改变胸腔容积以实现通气。
8. Nervous and Hormonal Coordination | 神经与激素协调
The nervous system uses fast electrical impulses, whereas the endocrine system uses slower chemical hormones transported in blood. A neuron includes dendrites, cell body, axon, myelin sheath and synaptic knobs. The junction is a synapse where a chemical transmitter diffuses across the gap.
神经系统使用快速的电冲动，而内分泌系统使用经血液运输的较慢的化学激素。 神经元 包括树突、细胞体、轴突、髓鞘和突触小结。连接处为 突触，化学递质在此处扩散过间隙。
Reflex arc — sensory neuron → relay neuron (in spinal cord) → motor neuron → effector. Use the sequence 'Romeo Sings Romantic Melodies Everyday' (Receptor, Sensory, Relay, Motor, Effector).
反射弧 — 对刺激做出的快速、不随意反应，绕过了意识脑。路径：感受器 → 感觉神经元 → 联络神经元 (脊髓中) → 运动神经元 → 效应器。使用句子 'Romeo Sings Romantic Melodies Everyday' 记忆顺序。
Insulin — hormone produced by pancreas, lowers blood glucose by converting it to glycogen in liver. Glucagon does the opposite. Both maintain homeostasis. Homeostasis — maintenance of a constant internal environment. Recall: 'homeo-' similar, 'stasis' standing still.
胰岛素 — 胰腺分泌的激素，通过促进肝脏将血糖转化为糖原降低血糖。 胰高血糖素 作用相反。两者共同维持稳态。 稳态 — 维持恒定的内部环境。记住：'homeo-' 相似，'stasis' 静止不变。
ADH (anti-diuretic hormone) — controls water reabsorption in kidneys. 'Anti-diuretic' means against excessive urination. Thermoregulation — control of body temperature through sweating, shivering, vasodilation and vasoconstriction.
抗利尿激素 (ADH) — 控制肾脏对水的重吸收。'Anti-diuretic' 意思是对抗多尿。 体温调节 — 通过出汗、颤抖、血管舒张和血管收缩控制体温。
9. Genetics and DNA Vocabulary | 遗传学与DNA词汇
Genetics carries its own language. The nucleus contains chromosomes made of DNA. A gene is a length of DNA coding for a specific protein. Alleles are different versions of the same gene. Genotype is the combination of alleles, phenotype is the observable characteristic. Think 'Genotype = Genes, Phenotype = Physical'.
遗传学有其自身语言。 细胞核 含有由DNA构成的染色体。 基因 是一段编码特定蛋白质的DNA。 等位基因 是同一基因的不同版本。 基因型 是等位基因的组合， 表现型 是可观察的特征。记住：'Genotype = 基因型 (Genes), Phenotype = 物理表现 (Physical)'。
Dominant allele — always expressed when present (use capital letter). Recessive — only expressed when two copies are present (lowercase). Homozygous — two identical alleles (e.g. BB or bb). Heterozygous — two different alleles (e.g. Bb). 'Homo' = same, 'Hetero' = different.
显性 等位基因 — 存在时总会表达 (用大写字母)。 隐性 — 仅有两个拷贝时表达 (用小写)。 纯合 — 两个相同等位基因 (如 BB 或 bb)。 杂合 — 两个不同等位基因 (如 Bb)。'Homo' = 相同，'Hetero' = 不同。
DNA is a double helix with complementary base pairing: Adenine–Thymine, Cytosine–Guanine. Memory aid: 'AT The Coast Guard'. Mitosis produces two genetically identical diploid daughter cells for growth and repair. Meiosis produces four genetically varied haploid gametes. Mitosis 'mends toe' (growth), Meiosis 'makes sex cells'.
DNA是双螺旋结构，具有互补碱基配对：腺嘌呤–胸腺嘧啶，胞嘧啶–鸟嘌呤。记忆窍门：'AT The Coast Guard'。 有丝分裂 产生两个遗传上相同的二倍体子细胞，用于生长和修复。 减数分裂 产生四个遗传上不同的单倍体配子。Mitosis '修复脚趾'，Meiosis '制造性细胞'。
Mutation — a random change in DNA base sequence. Can be neutral, harmful or occasionally beneficial. Natural selection — organisms with advantageous alleles are more likely to survive and reproduce, passing on those alleles.
突变 — DNA碱基序列的随机变化。可能是有害的、中性的或偶有益的。 自然选择 — 具有有利等位基因的个体更可能存活繁殖，并将这些等位基因传递下去。
10. Ecology and Fieldwork Terms | 生态学与野外调查术语
Ecology demands accurate use of terms describing populations and environments. Habitat — the place where an organism lives. Population — all members of one species in a habitat. Community — all populations of different species living together. Ecosystem — the community plus the abiotic factors.
生态学要求准确使用描述种群和环境的术语。 栖息地 — 生物居住的地方。 种群 — 同一栖息地中同一物种的所有成员。 群落 — 生活在一起的所有不同物种种群。 生态系统 — 群落加上非生物因素。
Producer — photosynthesising organism. Consumer — eats other organisms. Decomposer — breaks down dead organic matter. Trophic level — a feeding stage in a food chain. Use quadrats for sampling plants and slow-moving animals, and transects to study distribution along an environmental gradient.
生产者 — 进行光合作用的生物。 消费者 — 以其他生物为食。 分解者 — 分解死亡有机物质。 营养级 — 食物链中的一个取食层次。使用样方调查植物和移动缓慢的动物，使用样线沿环境梯度研究分布。
Biodiversity — the variety of living organisms in an area. Higher biodiversity often means a more stable ecosystem. Carbon cycle and nitrogen cycle recycle these elements. Eutrophication — excess nutrients in water leading to algal blooms and oxygen depletion. Trick: 'Eutro' sounds like 'eutro-fication' leads to 'eutro-bles' (troubles).
生物多样性 — 一个区域生物的种类多样性。更高的生物多样性通常意味着更稳定的生态系统。 碳循环 和 氮循环 循环这些元素。 富营养化 — 水体中过量养分导致藻华和氧气耗尽。窍门：'Eutro' 听起来像 '富营养引起麻烦'。
11. Common Antonyms and Confusable Pairs | 常见反义词与易混淆对
Many exam questions test your ability to distinguish closely related opposites. Create paired flashcards and always review them together.
许多考题检验你区分密切相关的反义词的能力。制作成对的闪卡，并总是一起复习。
| Term / 术语 | English Memory Hook | 中文记忆钩子 |
|---|---|---|
| Hypertonic vs Hypotonic | 'Hyper' sounds like 'higher' solute concentration; 'Hypo' like 'low'. Hypertonic = water leaves cell, cell shrinks. | 'Hyper' 像 'high' (高) 溶质浓度；'Hypo' 像 'low' (低)。高渗 = 水出细胞，细胞皱缩。 |
