传统的剑桥 Pre-U 生物（9760）资格考试已于 2023 年最后一次考试后正式退出。但对于在剑桥国际体系下准备冲刺大学生物科学方向的学生而言，目前对应的大学预科课程是 CIE AS 与 A Level 生物 9700 教学大纲。2025–2027 版新大纲带来了大量显著变化，这些变化将直接影响 2026 年的考试。本文系统分析内容范围、评估方式、实验技能与数据处理要求的关键变化，帮助学习者和教师把握大学预科生物学的演进趋势。
1. The Transition from Pre-U to the 2025–2027 A Level Syllabus | 从 Pre-U 到 2025–2027 A Level 大纲的过渡
The phasing out of Pre-U Biology pushed Cambridge International to consolidate its pre-university biology offer into a single updated A Level syllabus. The new 9700 syllabus deliberately retains the conceptual depth and independent-thinking ethos that Pre-U was known for, while aligning more closely with the updated Cambridge learner attributes and modern biological research. For 2026 candidates, this means a more streamlined but still rigorous course that rewards genuine understanding over rote recall.
Pre-U 生物的退出促使剑桥国际将其大学预科生物学整合为一套更新后的 A Level 大纲。新版 9700 大纲有意保留了 Pre-U 所著称的概念深度和独立思维导向，同时更贴合剑桥学习者特质与现代生物学研究。对 2026 年考生来说，这意味着一个更精简但仍具挑战性的课程，它奖励真正的理解而非机械记忆。
2. Overview of the 2026 Exam Series Under the New Syllabus | 2026 年考试系列与新大纲概览
From 2025 onwards, CIE A Level Biology follows a refreshed syllabus structure for examinations in June and November. The 2026 sitting represents the second full year of assessment under this new framework. Candidates take Paper 1 (Multiple Choice), Paper 2 (AS Structured Questions), Paper 3 (Advanced Practical Skills) for AS Level; additionally, Paper 4 (A Level Structured Questions) and Paper 5 (Planning, Analysis and Evaluation) for the full A Level. The syllabus code remains 9700, but the curriculum content and assessment objectives have been rebalanced.
从 2025 年起，CIE A Level 生物在 6 月和 11 月考季均采用更新后的大纲结构。2026 年考试是该新框架下的第二个完整评估年份。AS 阶段考生需参加 Paper 1（选择题）、Paper 2（AS 结构化问题）、Paper 3（高级实验技能）；完整 A Level 还需加考 Paper 4（A Level 结构化问题）和 Paper 5（计划、分析与评价）。学科代码仍为 9700，但课程内容和评估目标经过了重新平衡。
3. Content Removed and Added: A Leaner but Deeper Curriculum | 内容增删：更精炼、更深化的课程
Several topics that were previously covered in depth have been removed or reduced, such as some aspects of plant anatomy and detailed taxonomical classification. New content includes greater emphasis on epigenetics, bioinformatics, the human microbiome and antibiotic resistance mechanisms. The 2026 exams will expect candidates to discuss the roles of non-coding RNA, CRISPR-Cas9 gene editing and the evolutionary significance of horizontal gene transfer in prokaryotes.
原先要求深入掌握的若干主题已被删除或削弱，例如部分植物解剖细节和细致的分类学。新增内容包括对表观遗传学、生物信息学、人类微生物组和抗生素耐药机制的更多侧重。2026 年考试将期望考生能论述非编码 RNA 的功能、CRISPR-Cas9 基因编辑以及原核生物中水平基因转移的进化意义。
4. Greater Emphasis on Experimental Design and Data Evaluation | 更强调实验设计与数据评价
Paper 5 (Planning, Analysis and Evaluation) has been restructured with a sharper focus on open-ended planning questions. Students must demonstrate the ability to design controlled experiments, identify potential sources of systematic error and suggest realistic improvements. The 2026 papers will feature unfamiliar scenarios involving enzyme kinetics, respirometer measurements and colorimetric assays, requiring fluent use of statistical terms such as standard deviation, confidence limits and the t-test.
Paper 5（计划、分析与评价）经过重组，更聚焦于开放式的计划类题目。学生必须展示设计对照实验、识别潜在系统误差来源并提出切实可行的改进方案的能力。2026 年试卷将出现涉及酶动力学、呼吸计测量和比色分析的新情境，要求熟练运用标准差、置信限和 t 检验等统计术语。
5. Changes in Practical Assessment and Paper 3 | 实验评估与 Paper 3 的变化
While the core practical skills remain microscopy, biological drawing, biochemical tests and dilution series, the new syllabus introduces an expectation of quantitative treatment of observations. In Paper 3, candidates may be asked to calculate rates of reaction from raw data, estimate the accuracy of serial dilutions or evaluate the validity of a sampling technique using Simpson’s Index of Diversity. Microscopy tasks now include measuring cells with an eyepiece graticule and converting units consistently.
虽然核心实验技能仍是显微镜操作、生物绘图、生化检测和稀释系列，但新大纲引入了对观察结果进行定量处理的期望。在 Paper 3 中，考生可能被要求根据原始数据计算反应速率、评估连续稀释的准确性或用辛普森多样性指数评价采样方法的有效性。显微镜任务现在包括用目镜测微尺测量细胞并统一换算单位。
6. Updated Command Words and Question Styles | 更新的指令词与提问风格
To encourage higher-order thinking, the 2025–2027 syllabus sharpens the use of command words like ‘evaluate’, ‘suggest and explain’, and ‘justify’. In 2026, structured questions will often require synthesis across multiple topics; for example, linking cell signalling pathways to disease treatment or combining concepts from energy transfer and ecology in agricultural contexts. Students must practise identifying the exact demand of each command word under time pressure.
为鼓励高阶思维，2025–2027 大纲强化了 ‘evaluate’、’suggest and explain’、’justify’ 等指令词的运用。2026 年结构化问题常要求跨专题整合，例如将细胞信号通路与疾病治疗关联，或在农业情境中结合能量传递与生态学概念。学生必须反复练习在限时条件下准确识别每个指令词的要求。
7. The Rise of Bioinformatics and Genomic Data Interpretation | 生物信息学与基因组数据解读的崛起
One of the most notable trends is the infusion of bioinformatics across the syllabus. 2026 candidates will encounter data from DNA barcoding, phylogenetic trees derived from sequence alignment, and microarray heatmaps. Questions will not require computational coding but will test the ability to interpret BLAST results, identify conserved domains in protein structures, and deduce evolutionary relationships from nucleotide differences.
最引人注目的趋势之一是生物信息学在整个大纲中的渗透。2026 年考生将遇到来自 DNA 条形码、序列比对构建的系统发育树以及微阵列热图的数据。题目不要求编程，但会考查解读 BLAST 结果、识别蛋白质结构中保守结构域以及从核苷酸差异推断进化关系的能力。
8. Mathematics and Statistics Requirements Strengthened | 数学与统计学要求强化
CIE has increased the proportion of marks that reward quantitative skills to at least 10% of the overall A Level. For 2026, students should be confident in using logarithmic functions (e.g., pH in enzyme experiments), Chi-squared tests, Spearman’s rank correlation, and the Hardy–Weinberg equation expressed as p² + 2pq + q² = 1. Calculations of NPP from GPP and respiration data, as well as magnification conversions involving mm, μm and nm, remain essential.
CIE 已将奖励量化技能的分数比例提高到 A Level 总分至少 10%。到 2026 年，学生应熟练掌握对数函数（如酶实验中的 pH）、卡方检验、斯皮尔曼等级相关系数，以及以 p² + 2pq + q² = 1 表达的哈代–温伯格方程。根据 GPP 和呼吸数据计算 NPP，以及涉及 mm、μm 和 nm 的放大率换算，依然是必考基本功。
9. Human Health and Disease Now a Central Theme | 人类健康与疾病成为中心主题
In contrast to the previous Pre-U syllabus that sometimes treated human biology as a separate strand, the updated 9700 integrates health-related applications throughout. Topics like non-communicable diseases, the immune response to SARS-CoV-2, vaccination strategies using mRNA technology, and the development of monoclonal antibodies for cancer therapy are explicitly referenced. A 2026 candidate could be asked to explain how epidemiological data inform public health decisions.
不同于先前 Pre-U 大纲有时将人体生物学作为独立分支，更新后的 9700 将健康相关应用贯穿始终。非传染性疾病、对 SARS-CoV-2 的免疫应答、基于 mRNA 技术的疫苗策略以及用于癌症治疗的单克隆抗体开发等主题均被明确提及。2026 年考生可能被要求解释流行病学数据如何为公共卫生决策提供依据。
10. Ecology and Sustainability: A Modernised Perspective | 生态学与可持续发展：现代化视角
The new syllabus moves away from rote learning of specific named species and toward understanding ecological principles through case studies of climate change, biodiversity loss and conservation genetics. In 2026, expect questions on carbon fluxes in peatland restoration, the role of mycorrhizal networks in nutrient cycles, and the use of satellite data for monitoring deforestation. Students must be able to calculate carbon footprints and assess the reliability of different sampling strategies.
新大纲摒弃了对特定物种名称的死记硬背，转而通过气候变化、生物多样性丧失和保护遗传学案例研究来理解生态学原理。2026 年可能出现关于泥炭地恢复中碳通量、菌根网络在养分循环中的作用以及利用卫星数据监测森林砍伐的题目。学生必须会计算碳足迹并评估不同采样策略的可靠性。
11. Implications for Revision and Teacher Preparation | 对复习与教师备课的启示
Teachers and students preparing for the 2026 exam should prioritise interleaved practice that blends old and new content. Using Cambridge-endorsed textbooks aligned with the 2025–2027 syllabus is critical, as older resources may lack epigenetics or bioinformatics material. Regular timed attempts at Paper 5 data-analysis questions using unfamiliar contexts will build the evaluative mindset needed for top bands. Accessing the updated mark schemes and examiner reports from the 2025 sitting is strongly recommended.
为 2026 年考试做准备的教师和学生应优先采用新旧内容交织的间隔练习。使用与 2025–2027 大纲匹配的剑桥认可教材至关重要，因为旧版资源可能缺少表观遗传学或生物信息学内容。定期限时练习 Paper 5 中涉及陌生情境的数据分析题，能培养出高分段所需的评价思维。强烈建议获取 2025 年考季更新后的评分方案和考官报告。
12. Looking Ahead: The Evolutionary Path of Pre-University Biology | 展望未来：大学预科生物学的演进路径
Although the Pre-U badge has gone, its emphasis on academic enquiry lives on in the restructured 9700 syllabus. The 2026 exams represent an important milestone where analytical rigour meets contemporary bioscience. Students who embrace the quantitative, interdisciplinary and evidence-based character of the new course will be best positioned not only for the examination hall but also for degree-level study in medicine, biotechnology and environmental sciences.
尽管 Pre-U 的标识已经退出，但它对学术探究的重视却在重组后的 9700 大纲中得以延续。2026 年考试是一个重要里程碑，标志着分析严谨性与当代生物科学的交汇。拥抱新课程的定量化、跨学科和循证特质的学生，不仅将在考场上占得先机，也为医学、生物技术和环境科学等学位阶段的学习做好了最佳准备。
