剑桥国际AS Level工程（9705）大纲已经历重大更新，2026年的考试将全面实施新标准。无论你是从2025年开始学习AS课程，还是已经熟悉旧版大纲，理解这些新要求都至关重要。本文详细解析了评估结构、内容重点和技能权重的关键变化，帮助你看清方向，自信备考2026年系列考试。
1. Introduction to the 2026 Syllabus | 2026年新版大纲简介
The syllabus code remains 9705, but Cambridge International refreshed the engineering curriculum to reflect modern industry practices and pedagogical research. This updated syllabus started being taught from September 2024, with the first AS examinations originally available in 2025. However, the 2026 examination series represents the first full, stable cycle, benefitting from any early adjustments made after the initial 2025 sittings. Centres and learners should treat the 2026 examination as the benchmark for the new standard.
大纲代码仍为9705，但剑桥国际更新了工程课程，以反映现代工业实践和教学研究成果。新大纲从2024年9月开始教学，AS首次考试本安排在2025年。但2026年考试系列代表着首个完全稳定的周期，将吸纳2025年首次考试后的任何早期调整。学校和考生应把2026年考试视为新标准的基准。
The new syllabus aims to foster a deeper understanding of engineering principles, problem-solving, and practical application. It reduces the emphasis on simple factual recall and instead rewards students who can analyse unfamiliar contexts and apply mathematics correctly. For AS learners, the most immediate change is the structure of the assessment components and the introduction of contemporary topics like sustainability and digital electronics.
新大纲旨在培养对工程原理、问题解决和实际应用的更深入理解。它减少了对简单事实记忆的侧重，转而奖励那些能够分析陌生情境并正确应用数学的学生。对AS学生来说，最直接的变化是评估结构以及可持续性、数字电子等现代主题的引入。
2. Assessment Objectives Redefined | 评估目标的重新定义
The three assessment objectives (AOs) have been rebalanced for the 2026 AS examination. AO1 (Knowledge and understanding) now carries approximately 30% of the total marks, down from 40% in the previous syllabus. AO2 (Application of knowledge and problem-solving) has risen to 50%, while AO3 (Analysis and evaluation) accounts for the remaining 20%. This shift places greater demand on your ability to use what you have learned in new engineering scenarios rather than just describing facts.
三项评估目标（AO）在2026年AS考试中重新平衡。AO1（知识与理解）现在约占总分的30%，低于旧大纲的40%。AO2（知识应用与问题解决）提升至50%，AO3（分析与评价）占20%。这一变化更看重你在新的工程情境中运用所学的能力，而非仅仅描述事实。
This reweighting affects how you should prepare. Rote learning of formulae and definitions will no longer secure high marks; you must practise applying those formulae to solve multi-step problems, often involving unit conversions and interpretation of data. Typical AO3 tasks will ask you to evaluate a design choice or recommend improvements with justification, reflecting real-world engineering decision-making.
权重调整影响了备考方式。死记硬背公式和定义不再能保证高分；你必须练习运用公式解决多步骤问题，这些题目通常涉及单位换算和数据解读。典型的AO3任务将要求你评估设计选择或提出改进建议并给出理由，反映真实世界的工程决策过程。
3. Paper 1: Structured Questions – New Layout and Emphasis | 试卷一：结构化问题的新布局与侧重
Paper 1 is a 1-hour 45-minute written paper worth 60 marks. Unlike some other Cambridge subjects, there is no multiple-choice component in the new AS Engineering. The paper contains a series of structured questions, many set in contexts that cut across different syllabus topics. A notable change for 2026 is the inclusion of longer, synoptic-style questions that require you to draw together knowledge from mechanics, materials, and electronics within a single problem.
试卷一为1小时45分钟的笔试，总分60分。与其他某些剑桥科目不同，新版AS工程没有选择题部分。试卷包含一系列结构化问题，许多题目的情境会跨越不同大纲主题。2026年的一个显著变化是融入了较长的综合性问题，要求你在单一题目中综合运用力学、材料和电子学等多个领域知识。
A new feature is the ‘engineering scenario’ question, which may occupy an entire page. You will be presented with a diagram, specification table, or brief, then asked to calculate parameters, select appropriate materials, and justify your reasoning. Mathematical demands have increased slightly, with at least 40% of the paper allocating marks for numerical working. You must show clear steps and include correct SI units to earn full credit.
一个新特色是“工程场景”题，可能占据整页篇幅。你会看到一副示意图、规格表或设计概要，然后要求计算参数、选择合适的材料并说明理由。数学要求略有提高，试卷中至少40%的分数分配给数值运算过程。你必须展示清晰的解题步骤并包含正确的国际单位制（SI），才能拿到满分。
The table below summarises the key Paper 1 details for 2026:
下表概括了2026年试卷一的关键信息：
| Feature | Detail |
|---|---|
| Duration | 1 hour 45 minutes |
| Total marks | 60 |
| Question types | Structured, including data-response and scenario-based questions |
| Mathematical weighting | Minimum 40% of marks |
| New focus areas | Sustainable practices, digital systems, and engineering ethics |
4. Paper 2/3: Practical Skills and Coursework Options | 试卷二/三：实践技能与课程作业选项
The practical assessment component has been redesigned. Centres can choose between Paper 2 (Practical Test) or Paper 3 (Coursework), both worth 60 marks. The Practical Test lasts 2 hours 30 minutes and typically involves hands-on tasks with materials, measurement instruments, and electronic components. The coursework route, on the other hand, allows candidates to undertake a single extended engineering project under supervised conditions, submitted as a portfolio.
实践评估部分已重新设计。考试中心可选择试卷二（实践测试）或试卷三（课程作业），两者均为60分。实践测试时长2小时30分钟，通常涉及使用材料、测量仪器和电子元件的动手任务。课程作业途径则允许考生在监督条件下完成一个扩展性工程项目，并以作品集形式提交。
For 2026, the marking criteria for both options have been tightened. Greater emphasis is placed on planning, risk assessment, and iterative design. In the Practical Test, you may be asked to take measurements, construct a simple circuit, or test a mechanical system, then critically evaluate your results. In coursework, you need to demonstrate evidence of research, prototyping, and reflection. Whichever route your school selects, practising safe workshop techniques and systematic data recording is vital.
2026年，两种选项的评分标准更加严格。规划、风险评估和迭代设计受到更高重视。在实践测试中，你可能会被要求进行测量、搭建简单电路或测试机械系统，然后批判性地评估实验结果。在课程作业中，你需要展示研究、原型制作和反思的证据。无论学校选择哪种途径，练习安全的车间操作技术和系统化数据记录都至关重要。
The practical component now also contributes to the assessment of mathematical skills, as you must process raw data, calculate uncertainties, and plot graphs. Make sure your calculator is set to degrees or radians appropriately and that you can rearrange equations such as P = F/A or V = IR confidently while under time pressure.
实践部分现在也涉及数学技能的评估，因为你需要处理原始数据、计算不确定度并绘制图表。确保计算器角度单位设置正确，并且能在时间压力下自信地整理公式，如P = F/A或V = IR。
5. New Content Areas in AS Engineering | AS工程的新内容领域
The 2026 syllabus introduces several new topics that reflect the evolving nature of engineering. Sustainable engineering is now a dedicated thread, requiring you to understand life-cycle assessment, renewable energy sources, and the environmental impact of materials. Digital electronics and programmable logic controllers (PLCs) have been expanded to include basic logic gates, truth tables, and microcontrollers, whereas the old syllabus focused primarily on analogue circuits.
2026年新大纲引入了若干反映工程演变的主题。可持续工程现在是一个专门领域，要求你理解生命周期评价、可再生能源以及材料的环境影响。数字电子和可编程逻辑控制器（PLC）内容已扩展，包括基本逻辑门、真值表和微控制器，而旧大纲主要聚焦模拟电路。
Another addition is engineering ethics and communication. You must be able to discuss ethical dilemmas, such as balancing cost against safety, and present technical information using standard drawing conventions and computer-aided design (CAD) references. While you will not be assessed on CAD operation in the exam, you need to interpret CAD-generated drawings and understand ISO limits and fits. This modernisation aims to align the qualification with university and industry expectations.
另一个新增内容是工程伦理与沟通。你必须能够讨论伦理困境，例如在成本与安全之间权衡，并使用标准绘图规范和计算机辅助设计（CAD）参考来呈现技术信息。虽然考试中不评估CAD操作技能，但你需要解读CAD生成的图纸，并理解ISO公差与配合。这一现代化举措旨在使资格证书与大学和行业期望接轨。
6. Mathematics and Application in Engineering | 工程中的数学与应用
Mathematical rigour is no longer an implicit part of the subject; it is now explicitly assessed with a minimum 40% weighting in Paper 1. You are expected to handle algebraic manipulation, trigonometry, vectors, and statistics with fluency. Common equations you will encounter include F = ma, E = ½mv², P = W/t, and the ideal gas law PV = nRT. You must be able to transpose these equations to solve for any variable and substitute values using consistent SI units.
数学严谨性不再只是隐含在学科中，现在明确作为评估内容，在试卷一中占至少40%比重。你需要熟练地进行代数运算、三角学、向量和统计处理。你将遇到的常见方程包括F = ma, Eₖ = ½mv², P = W/t 和理想气体定律PV = nRT。你必须能够变换这些方程来求解任意变量，并用一致的国际单位制数值代入。
In addition to pure calculation, you should feel comfortable estimating answers and checking the reasonableness of your results. For instance, if you calculate a bridge member’s stress as 5000 MPa when the yield stress of steel is around 250 MPa, you should recognise a potential error. Graph skills, including plotting linearised data (e.g., ln(y) against x) and extracting gradients, are frequently tested. Practice using your calculator efficiently, particularly for statistical functions and solving simultaneous equations.
除纯计算外，你还应能够进行估算并检查结果的合理性。例如，若你计算出桥梁构件的应力为5000 MPa，而钢的屈服应力约为250 MPa，就应该意识到可能存在错误。图表技能，包括绘制线性化数据（如ln(y)对x）和提取斜率，也经常被考查。请练习高效使用计算器，特别是统计函数与解联立方程的功能。
7. Exam Technique for 2026 – What’s Different? | 2026年考试技巧 – 有何不同？
Successful exam technique now hinges on command words. Cambridge has placed greater prominence on terms like ‘explain’, ‘justify’, ‘evaluate’, and ‘determine’. A question asking you to ‘state’ requires a brief answer, whereas ‘explain’ demands a clear step-by-step reasoning. Many marks were lost in early trials because candidates gave simple descriptions when a justification was required. Practise annotating questions and linking your answers to the specific context given.
如今，成功的考试技巧关键在于指令词。剑桥更加重视“解释”、“论证”、“评价”和“确定”等术语。要求“陈述”的题目只需简短回答，而“解释”则需要清晰的逐步推理。在早期测试中，许多考生因需论证时只给出简单描述而失分。请练习标注问题，并将答案与给定的具体情境相联系。
Time management is more challenging with the new scenario-based questions. Allocate approximately 1.5 minutes per mark as a guide. For a 60-mark paper in 105 minutes, you have just over 1.7 minutes per mark, but some three-mark questions can consume an equal amount of thinking time. Always read the entire question before beginning; diagrams often contain critical data. Show all working even if you use a calculator, because marks are awarded for method as well as the final answer.
新的场景类题目使时间管理更具挑战性。可按每分钟约1.5分的标准分配时间。对于105分钟内60分的试卷，每分大约有1.7分钟，但有些3分题可能也耗费等量的思考时间。务必先通读整题再下笔，图表中常包含关键数据。即使使用计算器也要展示全部过程，因为方法步骤和最终答案一样计分。
8. Mark Scheme and Grading Updates | 评分标准与等级划分更新
Grade thresholds for the 2026 AS Engineering will be determined after each examination series, but the underlying mark schemes have been revised to reward more precisely the application of knowledge. An ‘A’ grade candidate typically demonstrates consistent accuracy in calculations, clear communication of logical steps, and the ability to make extended evaluative comments. The tolerance for numerical errors has narrowed; examiners expect final answers to be given to an appropriate number of significant figures, usually 2 or 3, based on the data provided.
2026年AS工程的等级分数线将在每次考试系列后确定，但基础评分标准已作修订，以便更精准地奖励知识应用能力。通常，“A”等考生展现出持续的计算准确性、清晰的逻辑步骤表达以及进行延伸性评价的能力。对数值误差的容忍度已收紧；考官期望最终答案根据所给数据保留适当的有效数字，通常为2或3位。
Additionally, spelling, punctuation, and grammar (SPaG) are not separately assessed, but clarity of written communication is intrinsic to high-level responses. When you ‘justify’ a material choice, coherent sentences that reference properties (like tensile strength, corrosion resistance, or specific stiffness) earn more than bullet points. Remember that all papers contribute equally to the AS qualification, so you cannot afford to neglect the practical component when calculating your overall grade.
此外，拼写、标点和语法虽不单独评分，但书面表达的清晰度是高水平回答的内在要求。当你“论证”材料选择时，引用属性（如抗拉强度、耐腐蚀性或比刚度）的连贯句子比要点式罗列得分更高。请记住，所有试卷对AS资格成绩的贡献相同，因此在估算总成绩时不可忽视实践部分。
9. Preparing for the 2026 AS Exam: Study Strategies | 2026年AS考试备考策略
Begin by downloading the official 2024-2026 syllabus from the Cambridge International website and use it as your revision checklist. Highlight the learning outcomes you feel least confident about, especially in the new content areas like sustainability and digital systems. Create topic summaries that link theory to real-world examples – for instance, explain how a cantilever beam works by referencing a balcony or an aircraft wing.
从剑桥国际官网下载官方2024-2026大纲，并将其作为复习清单。将你感到最没把握的学习成果标出，特别是可持续性和数字系统等新内容领域。制作主题摘要，将理论与现实示例联系起来——例如，通过阳台或飞机机翼来解释悬臂梁的工作原理。
Past papers from the previous 9705 syllabus remain somewhat useful for practising core mechanics and materials questions, but you must supplement them with the new specimen papers and any updated resources provided by Cambridge. Focus on the 2023 specimen paper for 2026 onward, which reflects the current style. When self-marking, refer to the mark scheme to understand how partial marks are allocated; you will notice that awarding of marks for ‘method’ is very generous, provided your working is logical and clearly set out.
旧版9705大纲的历年真题在练习核心力学和材料题方面仍有一定用处，但必须辅以新样卷和剑桥提供的任何更新资源。重点关注面向2026年及以后的2023年版样卷，其反映当前风格。自行批改时，请参照评分标准了解部分分数的分配方式；你会发现，只要步骤逻辑清晰且表述明确，“方法”分给得非常慷慨。
Practical skills cannot be crammed in the final weeks. If your centre conducts the Practical Test, request extra lab time to practice using vernier callipers, micrometers, oscilloscopes, and multimeters. Record measurements in a well-organised table and learn to identify anomalous readings. For coursework candidates, maintain a detailed logbook from day one, noting every design iteration, test result, and decision rationale. This evidence directly supports high attainment in AO3.
实践技能无法在最后几周突击。若你所在中心进行实践测试，请申请额外实验时间去练习使用游标卡尺、千分尺、示波器和万用表。将测量数据记录在井井有条的表格中，并学会识别异常读数。对于课程作业考生，从第一天起就保持详细的日志，记录每一次设计迭代、测试结果和决策理由。这些证据直接支撑AO3的高分表现。
10. Common Pitfalls and How to Avoid Them | 常见误区及避免方法
One recurring mistake is unit inconsistency. When calculating density, ensure mass is in kg and volume in m³. If given dimensions in mm, convert to m before substituting into equations. A simple miscalculation like using cm² instead of m² when evaluating stress can lead to an error of several orders of magnitude. Always write units in your working, not just the final answer, to catch such slips early.
一个经常出现的错误是单位不一致。计算密度时，确保质量以kg为单位，体积以m³为单位。如果给出的尺寸是mm，代入方程前先转换为m。在评估应力时，若错误地将cm²当作m²使用，可能导致若干数量级的偏差。务必在运算过程中书写单位，而不仅是最后答案，以便尽早发现此类失误。
Another pitfall is overcomplicating simple concepts. The new syllabus emphasises application, but the underlying principles remain constant. Do not write long paragraphs of background theory when the question asks for a specific calculation. Conversely, when asked to ‘evaluate’, avoid a one-line answer. Structure your evaluation with a brief statement of the pros and cons, supported by numerical evidence or principles, and end with a well-reasoned conclusion.
另一个陷阱是将简单概念复杂化。新大纲强调应用，但基本原理不变。当题目要求具体计算时，不要长篇大论背景理论。反过来，当被要求“评价”时，避免只写一行答案。评价的结构应为：简要陈述优缺点，以数值证据或原理为支撑，最终给出有理有据的结论。
Finally, many students neglect reading the stem of the question carefully. A scenario about a solar-powered water pump might provide efficiency data that you must use in subsequent parts. Missing that piece of information can cost several marks. Underline key data and define variables before you start solving. Consistent practice with this approach will build both speed and accuracy for the 2026 examination.
最后，许多学生疏于仔细阅读题干。关于太阳能水泵的情景题可能提供了效率数据，你必须在后续部分使用。遗漏那条信息会导致丢分。开始解题前，划出关键数据并定义变量。坚持用此方法练习，将为2026年考试带来速度与准确性的双重提升。
