📚 IGCSE CIE Biology: Exam Syllabus Overview | IGCSE CIE 生物：考试大纲解读
The Cambridge IGCSE Biology syllabus (0610) is designed to provide a broad, coherent understanding of biological principles, encouraging learners to develop an informed interest in science and scientific inquiry. This article provides a comprehensive overview of the syllabus structure, assessment components, key topics and examination tips to help students navigate the course effectively, from the first lesson to the final paper.
剑桥 IGCSE 生物教学大纲 (0610) 旨在提供广泛而连贯的生物学原理理解，鼓励学习者培养对科学和科学探究的兴趣。本文全面概述大纲的结构、评估组成、关键主题和考试技巧，帮助学生从第一节课到最后一门试卷都能高效地学习本课程。
1. Why the Syllabus Document Matters | 大纲文件为何重要
The syllabus is not simply a list of content. It is the contract between Cambridge Assessment International Education, your teacher and you. Every question in every paper is written against this document, so anything printed inside it is fair game, and anything absent from it will not be examined. Reading it once at the start of the course, and again before mocks, is one of the highest-value hours you can spend.
大纲不只是内容清单，它是剑桥国际考评部、你的老师和你的三方契约。每份试卷的每道题都依据该文件命制，因此凡是写在里面的内容都可能被考，凡是没写的内容则不会考。课程开始时读一遍、模考前再读一遍，是回报率最高的一个小时。
The syllabus aims to develop skills such as problem-solving, data analysis and the application of biological concepts to new situations. It also prepares students for further study in biology and related fields, which is why the wording of the aims and assessment objectives deserves as much attention as the topic list itself.
教学大纲旨在培养解决问题、数据分析以及把生物学概念应用于新情境等技能，也为学生在生物学及相关领域深造做好准备。正因如此，大纲中"目标"和"评估目标"部分的措辞，与主题清单本身同样值得关注。
Finally, the syllabus document includes definitions of command words, a glossary and a detailed content checklist. Teachers and students should use these resources for planning, revision timetables and self-assessment.
最后，大纲文件包括指令词定义、术语表和详细的内容核对清单。师生应利用这些资源进行课程规划、复习时间表和自我评估。
2. Structure of the Course | 课程结构
The syllabus is divided into 21 topics, covering both basic concepts and more advanced material. It is examined through a series of papers that test knowledge, understanding and practical skills. Students can choose between the Core and Extended levels of study, and the choice affects every paper they sit.
该教学大纲分为 21 个主题，涵盖基本概念和更高阶内容。它通过一系列试卷来考查知识、理解和实验技能。学生可选择学习核心 (Core) 或扩展 (Extended) 等级，这一选择会影响他们参加的每一份试卷。
The 21 topics run from the characteristics of living organisms through to human influences on ecosystems, and they are organised so that later topics build on earlier ones. Cell structure, biological molecules and enzymes underpin transport, gas exchange, respiration and excretion; genetics and ecology in turn depend on reproduction, variation and selection.
这 21 个主题从生物的特征一直延伸到人类对生态系统的影响，其编排方式使后面的主题建立在前面主题之上。细胞结构、生物分子和酶支撑着运输、气体交换、呼吸和排泄；而遗传学和生态学又依赖生殖、变异与选择。
Because the topics are interlinked, isolated memorisation rarely works. Examiners frequently combine two or three topics in a single structured question, for example asking you to link enzyme activity, diffusion and surface area to volume ratio in one context.
由于主题之间互相联系，孤立地死记硬背往往行不通。考官经常在一道结构题中组合两三个主题，例如要求你在同一个情境中把酶活性、扩散和表面积与体积之比联系起来。
3. The 21 Topics at a Glance | 21 个主题一览
The table below lists the topics in the order used by the syllabus. Use it as a checklist: tick each topic only when you can answer past-paper questions on it without notes.
下表按大纲顺序列出各主题。把它当作核对清单使用：只有当你合上笔记也能答出该主题的历年真题时，才给这一项打勾。
| # | English Topic | 中文主题 |
|---|---|---|
| 1 | Characteristics and classification of living organisms | 生物的特征与分类 |
| 2 | Organisation of the organism | 生物体的组织结构 |
| 3 | Movement into and out of cells | 物质进出细胞 |
| 4 | Biological molecules | 生物分子 |
| 5 | Enzymes | 酶 |
| 6 | Plant nutrition | 植物营养 |
| 7 | Human nutrition | 人体营养 |
| 8 | Transport in plants | 植物体内的运输 |
| 9 | Transport in animals | 动物体内的运输 |
| 10 | Diseases and immunity | 疾病与免疫 |
| 11 | Gas exchange in humans | 人体的气体交换 |
| 12 | Respiration | 呼吸作用 |
| 13 | Excretion in humans | 人体的排泄 |
| 14 | Coordination and response | 协调与反应 |
| 15 | Drugs | 药物 |
| 16 | Reproduction | 生殖 |
| 17 | Inheritance | 遗传 |
| 18 | Variation and selection | 变异与选择 |
| 19 | Organisms and their environment | 生物与其环境 |
| 20 | Biotechnology and genetic modification | 生物技术与基因改造 |
| 21 | Human influences on ecosystems | 人类对生态系统的影响 |
Topics 1 to 5 are usually taught first because they provide the vocabulary and concepts that everything else depends on. Topics 17 to 21 tend to appear in longer, data-rich questions, so they reward practice with graphs, tables and pedigree diagrams.
主题 1 至 5 通常最先教授，因为它们提供了其余内容所依赖的词汇与概念。主题 17 至 21 往往出现在篇幅较长、数据丰富的题目中，因此特别值得用图表、表格和系谱图来练习。
4. Core and Supplement Content | 核心与补充内容
The content is divided into Core and Supplement sections. Core topics are mandatory for all students and are assessed in Papers 1 and 3. Supplement topics include additional depth and are assessed in Papers 2 and 4 for those taking the Extended level. Supplement content is often indicated by a vertical line in the syllabus and extends beyond the Core.
内容分为核心与补充部分。核心主题是所有学生必修的，并在试卷一和试卷三中考查。补充主题包括更深入的内容，对于选择扩展等级的学生，将在试卷二和试卷四中考查。补充内容常以竖线标注在考纲中，其深度超出核心内容。
A useful habit is to go through the topic list with two coloured pens: one colour for content that appears in the Core column, another for the Supplement column. Anything in the Supplement column should be treated as examinable at the highest level if you are entered for Extended.
一个有用的习惯是用两支不同颜色的笔过一遍主题清单：一种颜色标出核心栏的内容，另一种标出补充栏的内容。如果你报考扩展等级，补充栏中的任何内容都应按最高要求来准备。
5. Papers 1 and 2: Multiple Choice | 试卷一与试卷二：选择题
Paper 1 is the Core multiple-choice paper and Paper 2 is the Extended multiple-choice paper. Both last 45 minutes and carry 40 marks, contributing 30 per cent of the final grade. Each question has four options, A to D, and there is no penalty for a wrong answer, so you should never leave a blank.
试卷一是核心选择题卷，试卷二是扩展选择题卷。两份试卷均为 45 分钟、40 分，占总成绩的 30%。每题有 A 到 D 四个选项，答错不扣分，因此绝不能留空。
Multiple-choice questions reward precision. A single word such as "always", "only" or "net" can eliminate two options instantly. Read the stem twice, predict your answer before looking at the options, then match it to the closest option rather than reading all four first.
选择题考查精确度。像 "always"、"only" 或 "net" 这样的一个词就可能立即排除两个选项。把题干读两遍，先自己预测答案再看选项，然后与最接近的选项匹配，而不是先通读四个选项。
Roughly one third of these questions are data-based: a graph, a table or a simple experiment. Practise reading axes, units and anomalous points, because these skills also carry marks in the theory papers.
其中约三分之一是数据类题目：一张图、一个表格或一个简单实验。要练习读取坐标轴、单位和异常点，因为这些技能在理论卷中同样占分。
6. Papers 3 and 4: Theory | 试卷三与试卷四：理论卷
Paper 3 is the Core theory paper and Paper 4 is the Extended theory paper. Both last 1 hour 15 minutes and carry 80 marks, contributing 50 per cent of the final grade, making them by far the most important papers in the qualification.
试卷三是核心理论卷，试卷四是扩展理论卷。两者均为 1 小时 15 分钟、80 分，占总成绩的 50%，是整项资格证书中最重要的试卷。
Questions are structured, meaning they are broken into parts (a), (b), (c) and so on, with the mark allocation printed for each part. A one-mark part needs one precise idea; a three-mark part usually needs three distinct points. The number of lines provided is a strong hint about the expected length of your answer.
题目为结构化设计，即分成 (a)、(b)、(c) 等小问，并标出每问的分值。一分的小问只需要一个准确的要点；三分的小问通常需要三个不同的要点。答题区提供的行数强烈暗示了答案应有的长度。
Extended papers contain more calculation, more multi-step reasoning and more questions that ask you to suggest or evaluate, for example explaining the effect of a change in enzyme concentration on the rate of an industrial reaction. Core papers focus more on recall and straightforward application.
扩展卷包含更多计算、更多多步推理，以及更多要求"提出建议"或"评价"的题目，例如解释酶浓度变化对工业反应速率的影响。核心卷则更侧重于记忆和直接应用。
7. Papers 5 and 6: Practical Assessment | 试卷五与试卷六：实验卷
Paper 5 is the Practical Test and Paper 6 is the Alternative to Practical. Both carry 40 marks and contribute 20 per cent of the final grade. Paper 5 lasts 1 hour 15 minutes and is taken in a laboratory, while Paper 6 lasts 1 hour and is a written paper based on familiar practical contexts.
试卷五是实验操作考试，试卷六是实验替代笔试。两者均为 40 分，占总成绩的 20%。试卷五为 1 小时 15 分钟，在实验室中进行；试卷六为 1 小时，是基于熟悉实验情境的笔试。
Both papers test the same underlying skills: recording observations accurately, drawing tables and graphs, identifying variables, calculating and evaluating results, and commenting on sources of error and how to reduce them.
两份试卷考查的核心技能相同：准确记录观察结果、绘制表格与图像、识别变量、计算与评价结果，以及指出误差来源和改进方法。
Even if you sit Paper 6, you must still do the practical work during the course. Questions are written from the perspective of a student who has handled the apparatus, so the ability to describe what you would actually see is essential.
即使你参加试卷六，课程期间仍必须完成实验操作。题目是从一名真正使用过仪器的学生的角度编写的，因此描述你实际会看到什么的能力至关重要。
8. Command Words, Glossary and the Content Checklist | 指令词、术语表与内容清单
Command words tell you what kind of answer earns marks. "State" means a short answer with no explanation. "Describe" means say what happens, in order, without giving reasons. "Explain" means give a reason, usually using "because" or "so that". "Suggest" means apply your knowledge to an unfamiliar situation.
指令词告诉你什么样的答案能得分。"State"（陈述）指简答，无需解释。"Describe"（描述）指按顺序说明发生了什么，不必给理由。"Explain"（解释）指给出原因，通常用 "because" 或 "so that"。"Suggest"（提出）指把所学知识应用于不熟悉的情境。
Other important command words include "calculate", "compare", "define", "identify", "outline", "predict" and "evaluate". Writing an explanation when the question only asked you to state wastes time, and writing a description when the question asked you to explain loses marks.
其他重要指令词还包括 "calculate"（计算）、"compare"（比较）、"define"（定义）、"identify"（识别）、"outline"（概述）、"predict"（预测）和 "evaluate"（评价）。题目只要求陈述你却写了解释，是在浪费时间；题目要求解释你却只写描述，则会丢分。
The glossary gives accepted definitions for key terms, and the content checklist lists every learning outcome. Turn each checklist line into a question and answer it aloud; this converts a passive document into an active revision tool.
术语表给出了关键术语的标准定义，内容清单则列出了每一条学习目标。把清单上的每一行改写成一个问题并口头作答，就能把一份被动的文件变成主动的复习工具。
9. Assessment Objectives and Skills | 评估目标与技能
The assessment objectives describe the balance of skills tested. Approximately half of the available marks reward knowledge and understanding, about a third reward handling information and problem solving, and roughly a fifth reward experimental skills and investigations.
评估目标描述了所考查技能的配比。大约一半的分数奖励知识与理解，约三分之一奖励信息处理与问题解决，约五分之一奖励实验技能与科学探究。
In practice this means that memorising facts alone can never secure a top grade. You must be able to read a graph, interpret a table, carry out a multi-step calculation and apply a familiar idea to an unfamiliar organism or industry.
在实践中，这意味着仅靠背诵事实永远无法拿到最高等级。你必须能够读图、解读表格、完成多步计算，并把熟悉的原理应用于陌生的生物或产业情境。
Data analysis skills appear across all papers, so improving them raises your score everywhere. A useful weekly task is to take one graph from a past paper and write three sentences that describe the trend, quote two data points and suggest one biological explanation.
数据分析技能出现在所有试卷中，因此提升它能在各处提高你的分数。一个有用的每周练习是：取历年真题中的一张图，写三句话——一句描述趋势，一句引用两个数据点，一句提出一个生物学解释。
10. Practical Skills and Experimental Design | 实验技能与实验设计
Practical questions reward precision with units and significant figures. Common calculations include the mean of repeat readings, percentage change, rate as a change per unit time, and magnification using the formula below.
实验类题目奖励在单位和有效数字上的精确性。常见计算包括重复读数的平均值、百分比变化、以单位时间变化量表示的速率，以及用下面公式计算的放大倍数。
magnification = image size ÷ actual size
When designing an experiment you should identify the independent variable, the dependent variable and at least two controlled variables. Then describe how the dependent variable is measured, how many repeats are taken, and how a control is set up.
设计实验时，你应识别自变量、因变量以及至少两个控制变量。然后说明因变量如何测量、重复几次，以及如何设置对照。
Evaluation marks come from judging data quality, not from listing every possible mistake. Saying "the temperature was not controlled, so the rate would be higher at higher temperatures" earns more than a vague statement that the experiment was inaccurate.
评价分来自对数据质量的判断，而不是罗列所有可能的错误。说"温度未加控制，因此温度较高时速率会更高"比笼统地说"实验不准确"更能得分。
Two biological ideas are worth learning as formulas because they explain so many observations.
有两个生物学概念值得作为公式来掌握，因为它们能解释大量观察结果。
surface area : volume ratio = surface area ÷ volume
rate of reaction = amount of reactant used ÷ time taken
Recall also the two key word equations that appear repeatedly in Papers 3, 4, 5 and 6.
还要牢记在试卷三、四、五、六中反复出现的两个文字方程式。
carbon dioxide + water → glucose + oxygen (light, chlorophyll)
glucose + oxygen → carbon dioxide + water (+ energy released)
11. Grades, Tiers and Entry Decisions | 等级、层级与报考决策
Grades run from A* to G. Candidates entered for the Core curriculum can achieve grades C to G, while candidates entered for the Extended curriculum can achieve grades A* to E. This is the single most important practical consequence of the tier you choose.
成绩等级从 A* 到 G。报考核心课程的学生可获得 C 至 G 的成绩，报考扩展课程的学生可获得 A* 至 E 的成绩。这是你选择层级所带来的最重要的实际后果。
Because Extended papers include both Core and Supplement content, a student entered for Extended who struggles may still answer the Core-level parts of each question. Partial credit is awarded, so a sensible strategy is to secure every Core mark first and then attack the Supplement marks.
由于扩展卷同时包含核心与补充内容，一位学习吃力的扩展考生仍可先回答每题中的核心层次部分。评分是按点给分的，因此一个明智的策略是先稳稳拿下所有核心分，再进攻补充分。
Grade boundaries are set after each examination session and vary with paper difficulty, so do not compare raw percentages across years. Compare your performance with the published boundaries for that specific session instead.
分数线在每次考试后划定，并随试卷难度变化，因此不要跨年份比较原始百分数。应当把成绩与当次考试公布的分数线相比较。
12. Revision Strategy and Exam Technique | 复习策略与考试技巧
Start with the syllabus checklist, not with a textbook. Mark each learning outcome as red, amber or green, then spend most of your remaining time on the red items. This prevents the common mistake of revising what you already enjoy.
