The 2026 examination session marks a pivotal moment for CIE A Level Biology (9700) candidates, as it represents the second year under the revised 2025–2027 syllabus. Understanding the structural and content overhaul introduced in 2025—and how it evolved in its first live assessment—is essential for Year 13 students aiming for top grades. This article dissects the changes in assessment format, key syllabus updates, and emerging trends to help you prepare effectively.
2026 年考试季是 CIE A Level 生物（9700）考生的一个关键节点，因为这是修订版 2025–2027 考纲实施的第二年。理解 2025 年引入的结构和内容改革，以及它在首次实考中的演变，对力争高分的 13 年级学生至关重要。本文将剖析评估形式的变化、考纲关键更新及新兴趋势，助你高效备考。
1. The 2025–2027 Syllabus Shift: Why It Matters for 2026 | 2025–2027 考纲转型：为何对 2026 年重要
In 2025, CIE replaced the legacy 9700 syllabus with a streamlined framework that better reflects modern biological science and contemporary assessment design. For the 2026 cohort, the syllabus is no longer brand-new; examiners have one full cycle of data to refine question difficulty and mark schemes, making a solid grasp of the changes even more critical.
2025 年，CIE 用一套更精简的框架取代了旧版 9700 考纲，这套框架更好地反映了现代生物科学和当代评估设计。对 2026 年考生而言，考纲已不再是全新内容；考官拥有一个完整考试周期的数据来调整试题难度和评分方案，因此透彻掌握变化显得更为关键。
The most dramatic shift is the consolidation of assessment components. The old five-paper A Level model (Papers 1–5) has been replaced by a four-paper structure, while the updated syllabus weaves cross-topic connections more explicitly. For retake or late-entry candidates familiar with the previous format, ignoring the new regime would be a high-risk strategy.
最显著的变化是评估模块的整合。旧版 A Level 五卷模式（试卷一至五）已被四卷结构取代，而更新后的考纲更明确地编织了跨主题联系。对于熟悉旧格式的重考或插班生而言，忽视新体系将是高风险策略。
2. Overview of the New Assessment Structure | 新评估结构概览
The reimagined 9700 assessment for A Level now comprises four components: Paper 1 (Multiple Choice, 1 h 15 min, 40 marks), Paper 2 (AS-Level Structured Questions, 1 h 15 min, 60 marks), Paper 3 (Advanced Practical Skills, 2 h, 40 marks) and Paper 4 (A-Level Structured Questions, 2 h, 100 marks). AS-only candidates sit Papers 1, 2 and 3.
重新设计的 9700 A Level 评估现在由四个部分组成：试卷一（选择题，1 小时 15 分钟，40 分）、试卷二（AS 结构化问答题，1 小时 15 分钟，60 分）、试卷三（高级实验技能，2 小时，40 分）和试卷四（A Level 结构化问答题，2 小时，100 分）。仅考 AS 的考生参加试卷一、二和三。
The disappearance of the former Paper 5 (Planning, Analysis and Evaluation) is the most headline-worthy change. Experimental design and data analysis skills are no longer isolated in a standalone paper but are instead embedded in Paper 3 and, to a significant degree, in Paper 4. This redistribution demands that students think like practicing biologists across all components.
原试卷五（实验设计、分析与评估）的消失是最受关注的变化。实验设计和数据分析技能不再孤立地出现在一张独立试卷中，而是嵌入试卷三，并在相当大程度上融入试卷四。这种重新分配要求学生在所有试卷中都能像一线生物学家那样思考。
3. Paper 1: The Expanded Multiple Choice | 试卷一：多选范围扩展
Unlike the old AS-only Paper 1, the new Paper 1 tests the full A Level syllabus—both AS and A2 topics—in 40 compulsory multiple-choice questions. This expansion means you can face items on gene technology, epigenetics and population genetics alongside familiar core concepts in the same 75-minute sitting.
与仅考查 AS 内容的旧版试卷一不同，新版试卷一测试完整的 A Level 考纲——涵盖 AS 和 A2 主题——共 40 道必答选择题。这次扩容意味着，你在 75 分钟的考试中可能同时遇到基因技术、表观遗传学和群体遗传学题目，与熟悉的核心概念一同出现。
For 2026, it is anticipated that the distractor design will become sharper, building on performance data from the 2025 cohort. Questions increasingly rely on data interpretation, diagrams and application rather than pure recall. Time management is crucial; you have just over 110 seconds per item, which leaves little room for hesitation on calculation-based or graph-interpretation questions.
预计 2026 年，干扰项的设计将依据 2025 年考生表现数据变得更加犀利。题目越来越依赖数据解读、图表和应用，而非纯粹记忆。时间管理至关重要；你每题只有略多于 110 秒，几乎没有余地对于计算类或图表解读题犹豫不决。
4. Paper 2: AS Structured Questions Revisited | 试卷二：AS 结构化问答重新审视
Paper 2 remains focused on the AS half of the specification, comprising a series of structured and free-response questions totalling 60 marks. However, the new syllabus subtly raises the demand for scientific reasoning; questions often ask you to 'suggest' explanations for unfamiliar biological scenarios, moving beyond simple description.
试卷二仍聚焦于考纲的 AS 部分，包含一系列结构化和自由作答题，共 60 分。然而，新考纲微妙地提高了对科学推理的要求；题目常要求你对不熟悉的生物情境“提出”解释，而不仅仅是简单描述。
The 2026 paper is expected to sustain the trend of integrating required practical knowledge into theoretical questions. Expect command words such as 'describe the role of...' or 'explain how...' to be twinned with practical scenarios you encountered in the laboratory, blurring the boundary between theory and hands-on work.
2026 年试卷预计将延续将必修实验知识融入理论题的趋势。要预期像“描述…的作用”或“解释…如何”这样的指令词会与你曾在实验室中遇到的实践情境配对，从而模糊理论与动手工作之间的界限。
5. Paper 3: The Unified Practical Examination | 试卷三：统一的实验考试
Paper 3 is the cornerstone of the new practical assessment. Replacing the old Paper 3 (AS practical) and absorbing elements of the retired Paper 5, this 2-hour, 40-mark examination requires you to carry out practical tasks, record observations, manipulate data, and draw conclusions—often within a single integrated question sequence.
试卷三是新实验评估的基石。它取代了旧版试卷三（AS 实验）并吸收了已淘汰的试卷五的部分要素，这场 2 小时、40 分的考试要求你完成实际操作任务、记录观察、处理数据并得出结论——通常是在一个完整的问题序列中完成。
For 2026, centres are likely to be more experienced in setting up the required apparatus, but students should still rehearse common laboratory techniques such as microscopy, colorimetry, enzyme rate investigations and food tests. The paper also tests your ability to evaluate limitations and suggest improvements—a skill formerly assessed in Paper 5 that now sits firmly within the practical hour.
到 2026 年，各考点在搭建所需仪器上可能更有经验，但学生仍应反复演练常见实验技术，如显微镜使用、比色法、酶速率探究和食物测试。该试卷也测试你评估局限性并提出改进建议的能力——这项过去由试卷五评估的技能现已牢牢嵌入实验时段中。
Mark schemes for Paper 3 place a premium on precise qualitative and quantitative recording, correct significant figures and units, and logical, evidence-based conclusions. Practice under timed conditions remains the most reliable preparation method.
试卷三的评分方案高度重视精确的定性与定量记录、正确的有效数字与单位，以及合乎逻辑、基于证据的结论。在限时条件下练习仍是最可靠的备考方法。
6. Paper 4: A Level Structured Questions – Depth and Integration | 试卷四：A Level 结构化问答 – 深度与综合
Paper 4 is now the flagship written paper, carrying 100 marks over 2 hours. It assesses the A2 topics in depth but also weaves in AS content to test synoptic understanding. A typical Paper 4 question might connect membrane transport with kidney function and hormonal control, demanding seamless recollection across the full two-year course.
试卷四是如今的旗舰笔试，100 分，时长 2 小时。它深入考查 A2 主题，但也融入 AS 内容以测试综览性理解。一道典型的试卷四题目可能将膜转运与肾脏功能和激素调控联系起来，要求你无缝回忆整个两年课程的内容。
Because the former Paper 5 has vanished, a significant portion of the 2026 Paper 4 will involve interpreting unfamiliar experimental data, critiquing experimental design, and applying statistical concepts like standard deviation, chi-squared tests and t-tests. Students must be comfortable selecting the appropriate statistical test and justifying their choice with biological reasoning.
由于原试卷五已被取消，2026 年试卷四的相当一部分将涉及解读陌生实验数据、评论实验设计，以及应用统计概念，如标准差、卡方检验和 t 检验。学生必须能够自如地选择恰当的统计检验，并用生物学推理来证明其选择。
The extended writing answer (often worth 8–10 marks) remains a feature, now frequently framed as an 'evaluate' or 'discuss' piece that requires balanced arguments, referencing both supporting and opposing biological evidence.
扩展作答题（通常 8–10 分）仍然保留，如今经常以“评估”或“讨论”题型出现，要求进行平衡论证，并引用支持和反对的生物学证据。
7. Key Content Additions and Removals | 关键知识点的增删
The 2025–2027 syllabus introduced several new topics that will remain firmly in the 2026 examinations. Epigenetics, including DNA methylation and histone modification, has been given explicit learning outcomes. The regulation of gene expression is now treated with greater molecular detail, encompassing transcription factors and RNA interference.
2025–2027 考纲引入的几个新主题在 2026 年考试中将继续牢固存在。表观遗传学，包括 DNA 甲基化和组蛋白修饰，已被赋予明确的学习成果。基因表达的调控现在以更深入的分子细节处理，涵盖转录因子和 RNA 干扰。
Gene technology has been refreshed to include up-to-date techniques like CRISPR-Cas9 gene editing, alongside traditional tools such as restriction enzymes and vectors. The ethical and social implications of genetic screening and stem cell use are also given more prominence, encouraging evaluative answers.
基因技术已更新，包含 CRISPR-Cas9 基因编辑等前沿技术，以及限制酶、载体等传统工具。遗传筛查和干细胞使用的伦理与社会影响也更受重视，这鼓励撰写评估性答案。
On the removal side, some detailed classification of lesser-known phyla and the sheer volume of plant-anatomy memorisation have been scaled back. This doesn't mean plant biology is unimportant—transport, photosynthesis and reproduction remain core—but the emphasis has shifted to processes and principles rather than morphological vocabulary.
在删减方面，一些较为冷门的门的详细分类以及大量植物解剖学记忆已被缩减。这并不意味着植物生物学不重要——运输、光合作用和生殖仍然是核心——但重点已从形态学词汇转向过程和原理。
8. Emphasis on Scientific Practices and Required Practicals | 重视科学实践与必修实验
The revised syllabus foregrounds a set of 12 required practical activities that all candidates should experience during the course. Although they are not assessed in a single separate practical endorsement, their fingerprints appear across all written papers, especially Papers 3 and 4.
修订版考纲突显了 12 项所有考生在课程期间都应经历的必修实验活动。尽管它们不作为独立实验签注被评估，但其痕迹在所有笔试试卷中——尤其是试卷三和四——均可见到。
For 2026, expect questions that assume you have personally carried out investigations on factors affecting enzyme activity, using a colorimeter or potometer, and preparing temporary mounts of plant tissues. The ability to identify variables, control risks, and handle anomalies is now a baseline expectation, not a bonus.
对 2026 年，要预期考题会假定你已亲自完成过影响酶活性的因素的探究、使用比色计或蒸腾计、制备植物组织临时装片。识别变量、控制风险和处理异常数据的技能如今是基本要求，而非加分项。
9. Shifts in Command Words and Mark Schemes | 指令词与评分方案的变化
CIE has refined the taxonomy of command words to better align with assessment objectives. For instance, 'state' requires a brief factual answer, while 'explain' demands a cause-and-effect chain using biological mechanisms. 'Evaluate' and 'discuss' now explicitly call for balanced conclusions weighing evidence from provided data against biological theory.
CIE 已细化指令词的分类体系，以更好地对接评估目标。例如，“陈述”要求简短的事实性回答，而“解释”则要求使用生物学机制的因果链。“评估”和“讨论”如今明确要求权衡所提供数据与生物学理论的平衡结论。
Mark schemes in 2026 will likely continue to reward use of precise scientific terminology. For example, writing 'condensation reaction forms a phosphodiester bond' earns marks faster than vague phrasing. Similarly, numerical answers must consistently show correct units and significant figures, a detail that cost many candidates marks in the 2025 debut.
2026 年的评分方案可能继续奖励精准科学术语的使用。例如，写出“缩合反应形成磷酸二酯键”比模糊措辞更快得分。同样，数值答案必须始终显示正确的单位和有效数字，这一细节在 2025 年首次考试中让许多考生失分。
10. Grade Boundaries and Performance Trends in 2026 | 2026 年等级分数线与成绩趋势
Following the new syllabus introduction, grade thresholds for 2025 were generally moderate, reflecting the transitional difficulty. Historical patterns suggest that by 2026, thresholds may rise slightly as both teachers and students become more acquainted with the demands, but they are unlikely to return to pre-pandemic levels immediately.
新考纲推出后，2025 年的等级分数线总体适中，反映了过渡期的难度。历史规律表明，到 2026 年，随着师生对要求更加熟悉，分数线可能略有上升，但不太可能立即回到新冠疫情前的水平。
A key trend to watch is the performance gap between Paper 3 and the theoretical components. In 2025, many candidates struggled with the integrated practical paper's time pressure. Centres that invested in regular hands-on practical sessions saw noticeably higher mean scores. For 2026, a similar pattern is expected, reinforcing the maxim that practical skill cannot be crammed.
一个需要关注的关键趋势是试卷三与理论部分之间的表现差距。2025 年，许多考生在综合实验试卷的时间压力下感到困难。那些投入定期动手实验的考点，平均分明显更高。2026 年，预期会出现类似模式，这印证了实践技能无法突击而成的格言。
11. Preparing for the 2026 Exams: Strategy and Resources | 备考 2026 年考试：策略与资源
Start by downloading the official 2025–2027 syllabus and the specimen papers from the CIE website. Use these documents to create a topic checklist that highlights new content areas such as epigenetics and CRISPR. Your revision should be syllabus-first, ensuring no learning outcome is left unaddressed.
首先从 CIE 官网下载官方 2025–2027 考纲和样卷。利用这些文件制作一个主题清单，突出表观遗传学和 CRISPR 等新增内容。你的复习应以考纲为先，确保每一个学习成果都不遗漏。
Integrate practical skills revision with theory: for each required practical, review the underlying biology, write out the key steps, and practice graph-plotting and statistical calculation under timed conditions. Past Paper 5 questions from the old syllabus remain useful for honing experimental design evaluation, even though the format has changed.
将实验技能复习与理论相结合：针对每一项必修实验，回顾背后的生物学原理，写出关键步骤，并在限时条件下练习绘图和统计计算。尽管格式已变，旧考纲中试卷五的真题对于磨炼实验设计评估能力仍有价值。
Form study groups that discuss recent biological research applications; the exam increasingly rewards those who can connect textbook knowledge to novel contexts. Finally, simulate full A Level papers (Papers 1, 2, 3 and 4) under realistic exam conditions at least twice before the final sitting to build mental stamina.
成立学习小组，讨论最近的生物学研究应用；考试越来越奖励那些能将课本知识与新情境联系起来的考生。最后，在正式考试前至少两次全真模拟完整 A Level 试卷（卷一、二、三和四），以锻炼心理耐力。
12. Looking Ahead: What 2026 Exam Trends Signal | 展望：2026 年考试趋势透露的信号
The 2026 examination will consolidate the 2025 reset. The trends point towards a biology qualification that prizes conceptual fluency over factual regurgitation, seamless integration of practical insight, and the confident use of mathematical and statistical tools. This mirrors the direction of higher education and biotech industries, where problem-solving with incomplete data is the norm.
2026 年考试将巩固 2025 年的重塑。趋势表明，这一生物学资格推崇概念流畅而非死记硬背、无缝整合实践洞察力，以及自信使用数学和统计工具。这与高等教育和生物技术行业的发展方向一致，在这些领域，使用不完整数据解决问题是常态。
For the individual student, the message is clear: embrace the holistic nature of the new syllabus. The boundaries between 'theory', 'practical' and 'data analysis' have been deliberately blurred, and those who compartmentalise their learning will find the integrated questions challenging. Begin early, stay curious, and treat every practical session as a living lesson in scientific thinking.
对于学生个人，信息很明确：拥抱新考纲的整体性。“理论”“实践”和“数据分析”之间的界限已被刻意模糊，那些把学习割裂开来的学生将觉得综合题目富有挑战性。早些开始，保持好奇心，并将每一次实验课视为科学思维的生动课堂。
