1. Cell Biology Core Terms | 细胞生物学核心术语
Many cell structures can be remembered by their Greek and Latin roots. For instance, 'cyto' means cell and 'plasm' means fluid, so cytoplasm is simply 'cell fluid'. Mitochondrion comes from 'mitos' (thread) and 'chondrion' (granule), describing its thread-like inner membrane. Breaking words into familiar parts reduces the load on pure memorisation.
许多细胞结构的名称可以通过其希腊语和拉丁语词根来记忆。例如‘cyto’意为细胞，‘plasm’意为液体，因此 cytoplasm 就是‘细胞液’。线粒体 mitochondrion 源于‘mitos’（线）和‘chondrion’（颗粒），描述其线状的内膜。把单词拆分为熟悉的部分可以减轻纯机械记忆的负担。
| Term | Meaning | 记忆技巧 Memory Hack |
|---|---|---|
| cytoplasm | 细胞质 | 'Cyto' (cell) + 'plasm' (fluid) = cell fluid. 细胞液。 |
| mitochondrion | 线粒体 | Think of a 'mighty thread granule' — the powerhouse! 联想‘强大的线粒颗粒’。 |
| ribosome | 核糖体 | 'Ribo' from ribose sugar; miniature protein factories. 含核糖的小工厂。 |
| nucleus | 细胞核 | 'Nuc' = nut or kernel; the control centre. 像坚果核心的控制中心。 |
| cell membrane | 细胞膜 | A thin 'skin' with selective entry — imagine a bouncer at a club. 俱乐部入口的保安。 |
2. Enzymes & Digestion | 酶与消化
Enzyme names typically end in '-ase' mylase acts on amylose (starch), protease acts on proteins, and lipase acts on lipids. The 'lock and key' a key (substrate) fitting only its specific lock (active site). Another useful mnemonic is 'Denature' = 'DEform the NAture' when temperature or pH extremes break the enzyme's shape.
酶的名称通常以‘-ase’结尾，并源自其底物。淀粉酶 amylase 作用于淀粉 amylose，蛋白酶 protease 作用于蛋白质，脂肪酶 lipase 作用于脂质。‘锁－钥匙’模型是描述专一性的经典比喻；你可以想象一把钥匙（底物）只能打开特定的锁（活性部位）。另一个实用的助记法是‘denature’→‘DEform the NAture’，即高温或极端 pH 破坏了酶的形状。
| Term | 中文 | Memory Hack |
|---|---|---|
| active site | 活性部位 | The 'docking station' on the enzyme. 酶的停靠位点。 |
| substrate | 底物 | The molecule that undergoes change; 'sub' = under, it goes under the enzyme's action. 承受酶作用的分子。 |
| denaturation | 变性 | DEform the NAture — lose shape permanently. 永久失去形状。 |
| amylase | 淀粉酶 | Act on AMYLose in mouth and small intestine. 作用于口腔和小肠的淀粉。 |
3. Photosynthesis & Respiration | 光合作用与呼吸作用
roduces glucose and oxygen; respiration is exothermic (releasing energy). Use the mnemonic 'Grandma's Pie Requires Sugar': Glucose + Oxygen → ... for aerobic respiration? Actually, better: for the photosynthesis equation, 'Six CO₂ plus six H₂O, with light, yields C₆H₁₂O₆ plus six O₂'. The phrase 'Photosynthesis puts Light IN, Respiration lets Energy OUT' distinguishes the two processes. Also, 'Aerobic' means with oxygen; think 'Air-obic'.
光合作用和呼吸作用的方程式是核心。记住光合作用是吸热的（吸收光能）并产生葡萄糖和氧气；呼吸作用是放热的（释放能量）。‘Photosynthesis puts Light IN, Respiration lets Energy OUT’这句话可以区分两个过程。另外，Aerobic 意为有氧；联想‘Air-obic’。对于方程式，数一数原子：6 CO₂ + 6 H₂O → C₆H₁₂O₆ + 6 O₂。
| Term | 中文 | 速记法 |
|---|---|---|
| photosynthesis | 光合作用 | Photo = light, synthesis = making — making with light. 用光制造。 |
| aerobic respiration | 有氧呼吸 | Air-obic = with air (oxygen). 带空气的。 |
| anaerobic respiration | 无氧呼吸 | An- = without, aerobic = oxygen → no oxygen. 无氧。 |
| fermentation | 发酵 | Anaerobic in yeast, producing CO₂ and ethanol. 酵母无氧产生 CO₂ 和乙醇。 |
4. Genetics & Inheritance | 遗传学与遗传
a section of DNA coding for a protein, an allele is a variant of a gene. Homozygous means 'same alleles' (homo = same), heterozygous means 'different alleles' hetero = different). Phenotype is the Physical appearance, Genotype is the Genetic make-up — use the first letters to link them. Dominant alleles overshadow recessive ones.
遗传学词汇中相似发音的词很多。从基本概念开始：基因是一段编码蛋白质的 DNA，等位基因是基因的变体。纯合子（homozygous）意为‘相同的等位基因’（homo = 同），杂合子（heterozygous）意为‘不同的等位基因’（hetero = 异）。表型 phenotype 是外表（Physical），基因型 genotype 是遗传组成（Genetic）——用首字母对应记忆。显性等位基因掩盖隐性等位基因的作用。
| Term | 中文 | Memory Hook |
|---|---|---|
| allele | 等位基因 | Different versions of a gene — imagine 'alternate leaves' on a plant. 替代版本。 |
| dominant | 显性 | Dominates the other allele; use capital letter. 大写字母，强势。 |
| recessive | 隐性 | Recedes in the background; lowercase letter. 小写字母，退隐后台。 |
| homozygous | 纯合子 | Homo = same — AA or aa. 相同等位基因。 |
| heterozygous | 杂合子 | Hetero = different — Aa. 不同等位基因。 |
5. Evolution & Natural Selection | 进化与自然选择
The phrase 'Survival of the Fittest' d individuals with advantageous alleles are more likely to survive and reproduce. The term 'speciation' means the formation of a new species; think 'speci' = species, 'ation' volution is a change in allele frequency over generations, not an individual transforming.
‘适者生存’概括了自然选择，但还需要更深层的术语。变异天然存在，具有有利等位基因的个体更可能存活并繁殖。‘speciation’意为物种形成；记‘speci’=物种，‘ation’=过程。地理隔离常常是诱因。要记住，进化是等位基因频率在世代中的变化，而不是个体的突然改变。
| Term | 中文 | 速记线索 |
|---|---|---|
| natural selection | 自然选择 | Nature selects the best suited. 大自然筛选。 |
| variation | 变异 | Differences among individuals — think 'variety'. 个体差异。 |
| speciation | 物种形成 | New SPECIES creATION. 新物种创造。 |
| fossil | 化石 | Fossils are found in rock — imagine 'fossilised footprints'. 岩石中的痕迹。 |
6. Ecology & Cycles | 生态学与循环
d nitrogen cycles involve key processes: photosynthesis, respiration, combustion, decomposition, nitrogen fixation, nitrification, denitrification. To remember the nitrogen cycle actors, use 'Fix N for plants, then they Nitrify it, finally Denitrify back to air'. 'Decomposers' are like nature's recyclers.
生态学术语常由小到大排列：生物体→种群→群落→生态系统→生物群系。碳循环和氮循环涉及关键过程：光合作用、呼吸作用、燃烧、分解、固氮、硝化、反硝化。为记住氮循环的参与者，可用‘先固氮给植物，再硝化，最后反硝化回空气’。分解者好比大自然的回收者。
| Term | 中文 | Image / Mnemonic |
|---|---|---|
| population | 种群 | Same species in an area. 同区域同物种。 |
| community | 群落 | All populations together — a 'common unity'. 所有种群在一起。 |
| ecosystem | 生态系统 | Living + non‑living interacting. 生物与非生物相互作用。 |
| nitrogen fixation | 固氮 | N₂ gas 'fixed' into ammonia by bacteria. N₂ 被细菌固定成氨。 |
| decomposer | 分解者 | Bacteria & fungi breaking dead matter. 分解死物的细菌真菌。 |
7. Human Circulatory & Immune System | 人体循环与免疫系统
Key heart structures include atria (upper chambers) and ventricles (lower chambers). 'Artery' carries blood Away, 'Vein' returns blood — note the 'A' and 'V' pattern. Immune terms: pathogen (disease‑causing agent), antigen ('antibody generator'), antibody (protein that binds antigen). Remember platelets as 'tiny plates' that plug cuts; haemoglobin as 'haemo' (blood) + 'globin' (protein) that carries oxygen.
心脏的主要结构包括心房（上腔）和心室（下腔）。动脉 artery 将血液送走（Away），静脉 vein 将血液送回——注意首字母 A 和 V 的规律。免疫术语：病原体 pathogen（致病因子），抗原 antigen（抗体生成者），抗体 antibody（结合抗原的蛋白质）。记住血小板 platelets 就像堵住伤口的小盘子；血红蛋白 haemoglobin = haemo（血）+ globin（蛋白），携带氧气。
| Term | 中文 | Hint |
|---|---|---|
| atrium | 心房 | Atrium = entrance hall — blood enters here. 入口大厅。 |
| ventricle | 心室 | Ventricle = 'vent' — pushes blood out. 排出血液。 |
| artery | 动脉 | Artery away. A 对应 Away。 |
| vein | 静脉 | Vein towards heart. V 走向心脏。 |
| platelet | 血小板 | Small plate-like cell fragments for clotting. 小盘子状的凝血碎片。 |
| antibody | 抗体 | Y-shaped protein — 'anti' = against, 'body' = foreign. 对抗外来物的 Y 形蛋白。 |
8. Plant Transport Systems | 植物运输系统
nd phloem are often confused. Xylem transports water and minerals up from the roots; think 'Xy goes high'. Phloem translocates sugars bidirectionally; remember 'Phloem = food flows'. Transpiration is the loss of water vapour from leaves — 'trans-' means across, '-spiration' g relates to breathing, evoking water leaving through stomata. Guard cells open and close stomata; they look like sausage-shaped lips.
木质部和韧皮部经常被混淆。木质部 xylem 从根部向上运输水分和矿物质；记‘Xylem 向上’，因为字母 X 看起来像个向上的箭头。韧皮部 phloem 双向运输糖分；记‘Phloem = food flows’。蒸腾作用 transpiration 指叶片水蒸气的散失；‘trans-’跨越，像呼吸一样释放水汽。保卫细胞 guard cells 控制气孔开闭，形似香肠状的嘴唇。
| Term | 中文 | Clue |
|---|---|---|
| xylem | 木质部 | Xy = high (think X marks high point). 向上。 |
| phloem | 韧皮部 | Phlo = flow of food. 食物流动。 |
| transpiration | 蒸腾作用 | Transpiration = Trans-fer of water vapour + res-piration. 水蒸气转移。 |
| stomata | 气孔 | Tiny 'mouths' on leaves — stoma = mouth. 叶片上的小嘴。 |
| guard cells | 保卫细胞 | They guard the stomatal opening. 守卫气孔的细胞。 |
9. Classification & Taxonomy | 分类学
The hierarchy of classification can be remembered by a memorable sentence: 'King Philip Came Over For Good Soup' — Kingdom, Phylum, Class, Order, Family, Genus, Species. Binomial nomenclature uses the genus and species names, e.g. Homo sapiens. The genus is always capitalised, species lowercase, italicised when printed. Each rank narrows the group.
分类层级可用一句话记忆：‘King Philip Came Over For Good Soup’——界、门、纲、目、科、属、种。双名法使用属名和种名，如 Homo sapiens。属名首字母大写，种名小写，印刷时用斜体。每个等级逐步缩小群体范围。
| Term | 中文 | Mnemonic Link |
|---|---|---|
| kingdom | 界 | The largest group — King as the highest ruler. 最大的类群，如国王。 |
| phylum | 门 | Philip starts with P; body plan grouping. 身体结构门类。 |
| genus | 属 | Generic name shared by close species. 不同物种共享的通用名。 |
| species | 种 | The most
