The 2026 exam session marks the second year of the revised CAIE IGCSE Biology syllabus (0610/0970), which was first examined in 2025. For Year 10 students, understanding the refreshed content, evolved assessment objectives, and emerging question trends is crucial for top performance. This article provides a comprehensive breakdown of what has changed, what is emphasised, and how you can adapt your revision strategy to stay ahead.
2026年考试是修订版 CAIE IGCSE 生物大纲（0610/0970）的第二年考试，该大纲于2025年首次考核。对于10年级学生，理解更新的内容、变化的评估目标和新兴的题型趋势是取得高分的关键。本文全面解析了考试变化、重点方向以及如何调整复习策略以保持领先。
1. Syllabus Update for 2025–2027: What Year 10 Students Must Know | 2025–2027 大纲更新：10年级学生须知
As a Year 10 student targeting the 2026 exam, you will be assessed entirely on the 2025–2027 Cambridge IGCSE Biology syllabus. This version introduced significant content shifts, removed some traditional topics, and reinforced the application of biology in modern contexts. It is no longer sufficient to simply recall facts; the syllabus now demands deeper analytical thinking and stronger practical data interpretation skills.
作为一名以2026年考试为目标的10年级学生，你将被完全按照2025–2027年剑桥IGCSE生物大纲考核。该版本引入了重大内容调整，删除了一些传统主题，并加强了生物学在现代情境中的应用。仅仅回忆事实已经不够，大纲现在要求更深入的分析思维和更强的实验数据解读能力。
2. Changes in Assessment Objectives (AO1, AO2, AO3) | 评估目标变化（AO1、AO2、AO3）
One of the most impactful changes for 2026 candidates is the adjustment of assessment objective weightings. The table below compares the older format with the current structure:
对2026年考生影响最大的变化之一是评估目标比重的调整。下表对比了旧版与现行结构：
| Assessment Objective | Pre-2025 Weighting | 2025–2027 Weighting |
|---|---|---|
| AO1: Knowledge with understanding | 55% | 50% |
| AO2: Handling information and problem-solving | 25% | 30% |
| AO3: Experimental skills and investigations | 20% | 20% |
The increase in AO2 from 25% to 30% means that exam questions now place greater emphasis on interpreting unfamiliar data, making predictions, and solving problems using biological principles. While AO1 remains the largest component, the explicit link between theory and application is tested more rigorously. You will encounter more ‘suggest’ and ‘explain’ questions that require justifications rather than pure recall.
AO2从25%提升至30%意味着试题现在更加强调解读不熟悉的数据、做出预测以及运用生物学原理解决问题。虽然AO1仍是占比最大的部分，但理论与应用之间的直接联系被更严格地考查。你将遇到更多要求给出理由的’suggest’和’explain’类题目，而非单纯复述。
3. New and Expanded Content: Genetics, Biotechnology & Ecosystems | 新增与扩展内容：遗传学、生物技术与生态系统
The updated syllabus introduces a deeper treatment of genetic engineering. You must now describe the use of restriction enzymes to cut DNA, ligase enzymes to join fragments, and vectors (such as plasmids and viruses) to insert genes into host cells. The production of human insulin by genetically modified bacteria is a key example. Additionally, biotechnology topics, including large-scale fermenter design and the production of penicillin, are covered in greater depth, requiring understanding of controlled conditions like pH, temperature, and aseptic technique.
更新后的大纲对基因工程进行了更深入的处理。你现在必须描述使用限制酶切割DNA、连接酶连接片段以及载体（如质粒和病毒）将基因导入宿主细胞。通过转基因细菌生产人胰岛素是一个关键例子。此外，生物技术主题，包括大型发酵罐设计和青霉素生产，被更深入地涵盖，需要理解控制条件，如pH、温度和无菌技术。
Ecosystem material has been expanded to include detailed explanations of eutrophication, linking fertiliser runoff to algal blooms, oxygen depletion, and fish death. The carbon cycle and nitrogen cycle are retained but are now tested with more diagram interpretation questions, asking you to identify processes or predict consequences of disruptions.
生态系统内容已扩展，包括对富营养化的详细解释，将化肥径流与藻华、氧气耗尽和鱼类死亡联系起来。碳循环和氮循环保留，但现在更多以图表解读题考查，要求你识别过程或预测干扰的后果。
4. Removed Topics: No More Teeth and Flower Details | 删除的主题：告别牙齿与花的细节
To make room for applied biology, some traditional content has been cut. The structure of teeth, types of teeth, and dental care are no longer assessed. Similarly, the detailed anatomy of insect-pollinated and wind-pollinated flowers – such as labelling anthers, stigmas, and nectar guides – has been removed. You still need to understand the mechanisms of pollination and the differences between insect and wind pollination, but you will not be required to draw and label flower diagrams.
为了给应用生物学腾出空间，部分传统内容被删减。牙齿的结构、牙齿类型和牙齿护理不再评估。同样，虫媒花和风媒花的详细解剖结构——如标注花药、柱头和蜜导——已被删除。你仍然需要理解传粉的机制以及虫媒与风媒传粉的区别，但不需要绘制和标注花朵示意图。
This shift allows teachers to focus more on experimental design, natural selection, and global environmental challenges, which align with the higher AO2 and real-world application demands. Be aware, however, that knowledge of removed topics may still appear indirectly in applied contexts, so a basic awareness is not wasted.
这一转变使教师能够更专注于实验设计、自然选择和全球环境挑战，这符合更高的AO2和现实世界应用的要求。不过需要注意，被删除主题的知识仍可能间接出现在应用情境中，因此基础了解并非毫无价值。
5. Shift Towards Data Analysis and Evaluation Skills | 向数据分析与评价技能倾斜
2026 exam papers will feature a noticeable increase in data-based questions. You may be given a table of enzyme activity at different temperatures, a graph of population growth, or a diagram of water uptake under varying conditions. You will be expected to calculate rates, describe trends, compare data sets, and critically evaluate experimental reliability. For example, a question might ask, ‘Explain why the data from Experiment A is more reliable than Experiment B.’
2026年试卷将以显著增多的数据题为主。你可能会看到不同温度下酶活性的数据表、种群生长曲线图或不同条件下水分吸收的示意图。你需要计算速率、描述趋势、比较数据集并批判性地评价实验的可靠性。例如，一道题可能会问：’解释为什么实验A的数据比实验B更可靠’。
To succeed, train yourself to read axes carefully, identify outliers, and consider control variables. Always link data back to biological explanations rather than just repeating numbers. This skill development aligns with the AO2 boost and will be crucial in both Theory (Papers 3 and 4) and Alternative to Practical (Paper 6).
为成功应对，训练自己仔细读取坐标轴、识别异常值并考虑控制变量。始终将数据联系到生物学解释，而不仅仅是重复数字。这项技能的培养与AO2提升相呼应，并且在理论卷（试卷3和4）和实验替代卷（试卷6）中都至关重要。
6. Practical Skills Assessment: What’s Changed in Papers 5 & 6 | 实验技能评估：试卷5与6的变化
The practical assessment options remain Paper 5 (Practical Test) and Paper 6 (Alternative to Practical). However, the mark schemes now reward more explicit planning and reasoning. When describing an investigation, you must state the independent variable, dependent variable, control variables, and a clear method with justification. Questions might ask you to suggest an improvement to an experimental setup or to predict the effect of a change.
实验评估选项仍为试卷5（实验操作考试）和试卷6（实验替代考试）。但评分标准现在奖励更明确的计划与推理。在描述一项探究时，你必须陈述自变量、因变量、控制变量以及带有理由的清晰方法。问题可能要求你提出对实验设置的改进建议或预测某个改变的影响。
Another emphasis is on graphing and mathematical competency. Expect to plot line graphs or bar charts, draw best-fit curves, and perform calculations such as percentage change or magnification. Paper 6 often incorporates ‘design an investigation’ questions that mirror the skills needed for the individual investigation component, even though IGCSE does not have a formal internal assessment.
另一个重点是绘图与数学能力。预期你会绘制线图或条形图，画出最佳拟合曲线，并进行百分比变化或放大倍数等计算。试卷6常包含’设计一项探究’的问题，这些题目反映了独立探究所需的技能，尽管IGCSE没有正式的校内评估。
7. Command Words and Question Styles in 2026 | 2026年题干关键词与题型风格
Cambridge has sharpened its use of command words to align with the new objectives. ‘Describe’ requires a factual account from memory; ‘Explain’ pushes you to give reasons or mechanisms; ‘Suggest’ tests your ability to apply knowledge to a novel situation, often without a single correct answer. ‘Evaluate’ now appears more frequently, asking for pros and cons or justified conclusions based on data. Understanding the exact demand of each command word can prevent lost marks.
剑桥加强了对题干关键词的使用，以与新的评估目标匹配。’Describe’ 要求根据记忆给出事实描述；’Explain’ 推动你给出理由或机制；’Suggest’ 测试你将知识应用于新颖情境的能力，通常没有唯一正确答案。’Evaluate’ 现在出现得更为频繁，要求基于数据给出利弊或合理的结论。理解每个关键词的精确要求可以避免失分。
Additionally, question styles now blend topics. You might find a question that starts with a diagram of a plant’s vascular bundle, moves to transpiration data, and ends with an environmental evaluation. This integrated approach mirrors the cross-topic thinking needed for higher grades and rewards students who see biology as a connected whole.
此外，题型现在会融合多个主题。你可能会遇到一道题，开头是植物维管束示意图，接着是蒸腾作用数据，最后以环境评价收尾。这种综合方式反映了获得高等级所需的跨主题思维，并奖励那些将生物学视为一个整体的学生。
8. Grade Boundaries and Marking Trends | 等级分数线与评分趋势
With the syllabus refresh, grade boundaries have shown mild fluctuations. In the first 2025 sitting, thresholds for A* (or grade 9 on 0970) remained high and similar to pre-change years, but the components requiring AO2 skills acted as key differentiators. Marking trends indicate that vague answers are penalised more heavily; precise scientific vocabulary and logical structure in explanations attract credit. For example, stating ‘temperature increase denatures enzymes, altering the active site’ scores higher than ‘heat kills enzymes’.
随着大纲更新，等级分数线出现了轻微波动。在2025年首次考试中，A*（或0970的9级）的阈值仍然很高，与变化前相似，但考查AO2技能的试卷部分成为关键区分因素。评分趋势表明，模糊的答案会受到更严格的扣分；精确的科学词汇和解释中的逻辑结构能赢得分数。例如，陈述’温度升高使酶变性，改变了活性位点’比’加热杀死酶’得分更高。
Expect that 2026 boundaries will stabilise, but the distribution of marks will reward practical analysis and application over simple knowledge recall. Consistent use of conventions like proper units, labelled axes on graphs, and correct biological terminology will continue to make a critical difference at the top end.
预计2026年的分数线将趋于稳定，但分数分布将奖励实验分析和应用而非简单的知识回忆。始终如一地使用规范，如正确的单位、图表上标注的坐标轴以及准确的生物学术语，仍将在高分段产生关键影响。
9. Common Mistakes Students Make in the New Syllabus | 新大纲中学生的常见错误
Many Year 10 learners still treat the exam as a pure memory test. A frequent mistake is failing to embed data references in answers – for instance, describing a graph trend without quoting any figures, or stating a conclusion without mentioning control variables. Another pitfall is mixing up similar terms: ‘accuracy’ vs ‘reliability’, ‘independent variable’ vs ‘controlled variable’, or ‘transpiration’ vs ‘translocation’.
许多10年级学生仍将考试视为纯粹的记忆测试。常见的错误是在答案中未能引用数据——例如，描述图表趋势却不援引任何数字，或给出结论时未提及控制变量。另一个误区是混淆类似术语：’准确度’与’可靠性’、’自变量’与’控制变量’，或’蒸腾作用’与’转运’。
Also, in evaluation questions, students often list vague improvements like ‘do the experiment again’ instead of ‘repeat the investigation with a larger sample size and calculate a mean to improve reliability’. Under the updated mark scheme, specificity is rewarded, so practise phrasing your answers precisely.
此外，在评价题中，学生经常列出模糊的改进建议，如’再做一次实验’，而不是’用更大的样本量重复该探究并计算平均值以提高可靠性’。根据更新的评分标准，具体性会受到奖励，因此要练习精确地表述答案。
10. How Year 10s Can Prepare for the 2026 Exams | 10年级学生如何备战2026年考试
Start by securing a copy of the 2025–2027 syllabus and highlight all ‘State’, ‘Describe’, ‘Explain’, and ‘Suggest’ content indicators. Create active revision notes for the new biotechnology and genetic engineering topics, using flow diagrams for enzyme actions and fermenter control. Regularly practise past papers from 2025 and older papers that have been updated by Cambridge to reflect the new style, focusing particularly on data-response and experimental design questions.
首先获取一份2025–2027年大纲，并标出所有’State’、’Describe’、’Explain’和’Suggest’的内容指标。为新的生物技术和基因工程主题制作主动复习笔记，用流程图展示酶的作用和发酵罐控制。定期练习2025年真题以及剑桥为反映新题型而更新的旧试卷，特别关注数据应答和实验设计题。
Develop a habit of writing out full-sentence answers to AO2 questions and then checking against the mark scheme for missed points. Build a glossary of command words and their requirements. For practical skills, even if your school enters for Paper 5, practising Paper 6 past papers helps master the planning and evaluation logic. Collaborative study can also help exchange interpretations of tricky data sets.
养成对AO2问题写出完整句子答案、然后对照评分标准检查遗漏点的习惯。建立命令词及其要求的词汇表。关于实验技能，即使学校报考的是试卷5，练习试卷6真题也有助于掌握规划与评价逻辑。合作学习也可以帮助交流对棘手数据集的解读。
11. Future Trends and Predictions for IGCSE Biology | IGCSE生物未来趋势预测
Looking beyond 2026, CAIE’s direction suggests an even stronger integration of socio-scientific issues. Climate change biology, conservation genomics, and antimicrobial resistance are likely to appear in more contextual questions. The syllabus may gradually introduce concepts like bioinformatics and model organism research, aligning with global educational shifts.
展望2026年以后，CAIE的方向表明社会科学议题将进一步融合。气候变化生物学、保护基因组学和抗微生物耐药性很可能出现在更多情境题中。该大纲可能会逐步引入生物信息学和模式生物研究等概念，以与全球教育转变保持一致。
Consequently, developing a curiosity-driven approach to biology will remain valuable. Read science news, watch documentaries, and connect classroom content to real-world events. This practice not only prepares you for unforeseen questions but also builds the flexible thinking that top-tier universities and careers reward.
因此，培养好奇心驱动的生物学学习方式将始终有价值。阅读科学新闻、观看纪录片，并将课堂内容与现实事件相联系。这种做法不仅为你应对意外问题做准备，还能培养顶级大学和职业所奖励的灵活思维。
