剑桥 IGCSE 生物课程（0610/0970）是一项全球认可的资质，旨在培养对关键生物概念、实验技能和科学思维方式的深入理解。无论你参加核心课程还是扩展课程，准确了解试卷覆盖内容和结构对高效复习至关重要。本指南将全面拆解考试大纲，说明评估构成，并突出你需要掌握的核心主题与技能。
1. Syllabus at a Glance | 大纲总览
The Cambridge IGCSE Biology syllabus is designed to equip students with a comprehensive knowledge of the living world, from molecules to ecosystems. It is available in two tiers: Core and Extended. Core candidates aim for grades C to G (or 4 to 1 in the 9-1 system), while Extended candidates can achieve grades A* to E (9 to 3). The syllabus code for the A*-G grading is 0610, and for the 9-1 grading it is 0970.
剑桥 IGCSE 生物课程旨在让学生全面掌握从分子到生态系统的生命世界知识。课程分为核心和扩展两个层级。核心课程考生的目标成绩为 C 到 G（或 9-1 体系中的 4 到 1），而扩展课程考生可获 A* 到 E（9 到 3）的成绩。A*-G 评分的大纲代码为 0610，9-1 评分的代码为 0970。
The content is organised into 21 topics, ranging from cell biology and biochemistry to genetics and ecology. In addition, the syllabus emphasises practical skills and mathematical competence. The final grade is determined by three examination papers, with choices for the practical component.
内容分为 21 个主题，涵盖从细胞生物学和生物化学到遗传学和生态学的广泛领域。此外，大纲强调实验技能和数学能力。最终成绩由三份试卷决定，实验部分有不同选择。
2. Core vs Extended Tier | 核心与扩展课程
Core content is designed for students who need a foundational understanding of biology. It covers all the main topics but in less depth and with simpler contexts. Core candidates are examined via Paper 1 (Multiple Choice), Paper 3 (Theory), and either Paper 5 (Practical Test) or Paper 6 (Alternative to Practical).
核心内容面向需要掌握生物学基础的学生。它涵盖所有主要主题，但深度较浅，情境更简单。核心考生通过试卷 1（选择题）、试卷 3（理论题）以及试卷 5（实验考试）或试卷 6（实验替代）进行考核。
Extended content includes the Core material plus supplementary topics that delve deeper into biological mechanisms and applications. Extended candidates take Paper 2 (Multiple Choice), Paper 4 (Theory), and the same practical paper choice. Extended tier questions often require analysis, evaluation, and the ability to apply knowledge to unfamiliar situations.
扩展内容包含核心材料，并增加深入探究生物机制和应用的补充主题。扩展考生参加试卷 2（选择题）、试卷 4（理论题）和相同的实验试卷。扩展层级的题目往往要求分析、评价以及将知识应用于陌生情境的能力。
Choosing the right tier depends on your target grade and confidence with scientific reasoning. Your teacher will usually advise on which tier suits you best, but it’s important to understand that Extended tier has more demanding content, such as detailed heart structure, genetic engineering, and the nitrogen cycle.
选择合适的层级取决于你的目标成绩和对科学推理的信心。老师通常会建议最适合你的层级，但重要的是要知道扩展层级包含要求更高的内容，例如详细的心脏结构、基因工程和氮循环。
3. Assessment Overview: Papers and Weighting | 评估概览：试卷与权重
All candidates must take three papers. The combination depends on the tier and the practical option chosen. The table below summarises the paper structure for both Core and Extended tiers.
所有考生必须参加三份试卷。组合方式取决于所在层级和选择的实验方案。下表总结了核心和扩展层级的试卷结构。
| Tier / 层级 | Paper 1/2 (MCQ) / 选择题 | Paper 3/4 (Theory) / 理论题 | Practical / 实验 |
|---|---|---|---|
| Core | Paper 1 (45 min, 40 marks, 30%) | Paper 3 (1 h 15 min, 80 marks, 50%) | Paper 5 or 6 (20%) |
| Extended | Paper 2 (45 min, 40 marks, 30%) | Paper 4 (1 h 15 min, 80 marks, 50%) | Paper 5 or 6 (20%) |
Paper 1 and Paper 2 contain 40 multiple-choice questions each. Paper 3 and Paper 4 consist of short-answer and structured questions. Paper 5 is a practical test conducted in a laboratory, while Paper 6 is a written paper assessing practical skills, suitable for candidates without access to lab facilities. The practical component makes up 20% of the total qualification.
试卷 1 和试卷 2 各含 40 道选择题。试卷 3 和试卷 4 由简答题和结构化问题组成。试卷 5 是在实验室进行的实验考试，而试卷 6 是考查实验技能的笔试，适合无法使用实验室设施的考生。实验部分占总成绩的 20%。
4. Paper 1 & 2: Multiple Choice Secrets | 选择题的答题秘诀
These papers test breadth of knowledge across the entire syllabus. Core Paper 1 targets the Core syllabus only, while Extended Paper 2 includes both Core and Extended content. Each question has four options, and you must select the one correct answer. Time management is critical: you have just over one minute per question.
这些试卷测试对整个大纲知识面的掌握。核心试卷 1 仅针对核心大纲内容，而扩展试卷 2 包含核心和扩展内容。每个问题有四个选项，你必须选出唯一的正确答案。时间管理至关重要：每题只有一分钟多一点的时间。
Questions often include diagrams, graphs, and experimental setups. Common traps include distractors that use incorrect terminology, swap cause and effect, or present data that looks correct but is misinterpreted. Read all options carefully and eliminate obviously wrong answers first.
题目常包含示意图、图表和实验装置。常见陷阱包括使用错误术语的干扰项、因果倒置，或呈现看似正确但被曲解的数据。仔细阅读所有选项，首先排除明显错误的答案。
Key topics that appear frequently are enzyme action, transport in plants, the circulatory system, genetic crosses, and ecosystem interactions. Practice past papers to become familiar with the style and to recognise recurring question patterns.
频繁出现的关键主题包括酶的作用、植物运输、循环系统、遗传杂交以及生态系统相互作用。通过历年真题练习，熟悉题型并识别重复出现的出题规律。
5. Paper 3 & 4: Tackling Theory Questions | 应对理论题
The theory papers are the most heavily weighted, contributing 50% to your final grade. They demand not only recall but also application, analysis, and evaluation. Core Paper 3 and Extended Paper 4 both last 1 hour and 15 minutes and are marked out of 80. Extended paper questions require more detailed explanations and often include questions that assess AO2 (application) and AO3 (evaluation) skills.
理论题试卷权重最高，占最终成绩的 50%。它们不仅要求记忆，还要求应用、分析和评价。核心试卷 3 和扩展试卷 4 的考试时间均为 1 小时 15 分钟，满分 80 分。扩展试卷的问题需要更详细的解释，并经常包括评估 AO2（应用）和 AO3（评价）技能的题目。
Answers must demonstrate precise biological vocabulary. For example, instead of writing ‘the plant takes in water’, write ‘water enters root hair cells by osmosis down a water potential gradient’. Where possible, link your answer to the data or information given in the question.
答案必须使用准确的生物词汇。例如，不要写“植物吸收水分”，而应写“水分通过渗透作用，顺着水势梯度进入根毛细胞”。尽可能将答案与题目中给出的数据或信息相关联。
Extended candidates should be prepared for questions that combine topics, such as linking photosynthesis and respiration, or genetics and evolution. Practice writing logical, step-by-step explanations to secure maximum marks.
扩展课程考生应做好准备，应对融合多个主题的题目，例如将光合作用与呼吸作用关联，或遗传与进化结合。练习写出逻辑严谨、逐步推理的解释，以获取满分。
