剑桥 Pre-U 工程是剑桥大学国际考评部为 16 至 19 岁学生设计的严格线性资格考试，旨在深化学生对工程原理、应用和系统的理解。与模块化的 A-Level 不同，Pre-U 课程强调整体思维和独立探究，并设置了一个权重很高的个人项目。本文详细解析课程大纲的各个方面，为学生、教师和家长提供清晰的路线图。
1. What is Cambridge Pre-U Engineering? | 什么是剑桥 Pre-U 工程课程？
Cambridge Pre-U Engineering (syllabus code 9768) is a two-year advanced course that bridges theoretical knowledge and practical application. It challenges learners to think like engineers, integrating mathematics, physics and design in real-world contexts. The qualification is linear, meaning all examinations and coursework are taken at the end of the course, encouraging a deep and connected understanding of the subject.
剑桥 Pre-U 工程（大纲代码 9768）是一门为期两年的高级课程，连接理论知识和实际应用。它要求学习者像工程师一样思考，将数学、物理和设计融入真实场景。该资格是线性的，即所有考试和课程作业都在课程结束时进行，从而鼓励对学科形成深刻且连贯的理解。
2. Course Aims and Learning Outcomes | 课程目标与学习成果
The syllabus aims to develop students’ ability to analyse engineering problems systematically, apply scientific and mathematical principles creatively, and evaluate the ethical, environmental and economic impacts of engineering solutions. By the end of the course, learners should be able to design, model, test and refine engineering products or systems, and communicate their ideas effectively.
大纲旨在培养学生系统分析工程问题的能力，创造性地应用科学和数学原理，并评估工程解决方案的道德、环境和经济影响。课程结束时，学习者应能够设计、建模、测试和改进工程产品或系统，并有效交流自己的想法。
3. Syllabus Structure at a Glance | 大纲结构一览
The course comprises four components, each contributing 25% to the final grade. Three components are assessed by written examination, while the fourth is a coursework-based personal investigation. The following table summarises the structure:
该课程包含四个组件，每个组件占总成绩的 25%。其中三个组件通过笔试评估，第四个是基于课程作业的个人探究。下表总结了其结构：
| Component | Title | Assessment | Weighting |
|---|---|---|---|
| 1 | Engineering Principles | Written paper (2 h) | 25% |
| 2 | Engineering Applications | Written paper (2 h) | 25% |
| 3 | Engineering Systems | Written paper (2 h) | 25% |
| 4 | Personal Investigation | Coursework | 25% |
4. Engineering Principles (Component 1) | 工程原理（组件一）
This component grounds students in the essential physics and materials science that underpin engineering. Topics include mechanics, thermodynamics, fluid mechanics, electricity and electronics, and properties of materials. Learners must become fluent in applying key equations to solve quantitative problems.
该组件为学生奠定支撑工程的基础物理和材料科学知识。主题包括力学、热力学、流体力学、电学与电子学以及材料性能。学习者必须熟练运用关键方程解决定量问题。
For instance, stress is defined as force per unit area, and strain as extension per original length. These are expressed by the formulas:
例如，应力定义为单位面积的力，应变定义为伸长量与原长之比。它们用如下公式表达：
σ = F / A
σ = F / A
ε = ΔL / L₀
ε = ΔL / L₀
In electrical circuits, Ohm’s law and power equations are equally fundamental: V = I R and P = I V. Understanding these concepts allows students to analyse beams, engines, pumps and control circuits.
在电路中，欧姆定律和功率方程同样基础：V = I R 以及 P = I V。理解这些概念使学生能够分析梁、发动机、泵和控制电路。
5. Engineering Applications (Component 2) | 工程应用（组件二）
Building on the principles, this paper focuses on how engineering theory is applied in practice. It covers structures, machines, energy systems, electronic circuits and design processes. Students learn to read and interpret engineering drawings, select appropriate materials, and evaluate the performance of existing designs.
基于原理，这份试卷聚焦于工程理论如何在实践中应用。它涵盖结构、机器、能源系统、电子电路和设计流程。学生学习阅读和解释工程图纸、选择合适材料并评价现有设计的性能。
Typical scenarios might involve analysing a bridge truss, choosing a gear train for a lifting mechanism, or designing a simple amplifier circuit. The emphasis is on problem-solving within realistic constraints, including cost, safety and sustainability.
典型情境可能包括分析一座桥梁桁架、为起重机构选择齿轮传动系统，或设计一个简单的放大电路。重点是在成本、安全性和可持续性等现实约束下解决问题。
6. Engineering Systems (Component 3) | 工程系统（组件三）
This component takes a holistic view, exploring how individual engineering elements combine into complex systems. Topics include control theory (open and closed loops), feedback, dynamic response, energy management, communication systems and sustainable design. Students use block diagrams and mathematical models to describe system behaviour.
该组件从整体视角出发，探索各个工程元素如何组合成复杂系统。主题包括控制理论（开环与闭环）、反馈、动态响应、能量管理、通信系统和可持续设计。学生使用框图及数学模型来描述系统行为。
An example is the PID controller, whose transfer function can be represented as:
一个例子是 PID 控制器，其传递函数可以表示为：
G(s) = Kₚ + Kᵢ/s + K_d s
G(s) = Kₚ + Kᵢ/s + K_d s
Questions might ask students to predict the step response of a mechanical servo or propose improvements to a renewable energy grid. Systems thinking is crucial for modern engineering.
问题可能要求学生预测机械伺服系统的阶跃响应，或对可再生能源电网提出改进建议。系统思维对现代工程至关重要。
7. Personal Investigation (Component 4) | 个人探究（组件四）
The personal investigation is a coursework component that allows students to pursue an engineering project of their own choice. It must involve designing, making, testing and evaluating a prototype or system, and the final report should document the entire iterative process. This component fosters independent research, creativity and practical skills.
个人探究是一个课程作业组件，允许学生自己选择一个工程项目进行探究。它必须包括设计、制作、测试和评估一个原型或系统，最终报告应记录整个迭代过程。该组件培养独立研究、创造力和实践技能。
Projects range from autonomous vehicles and bridge models to electronic weather stations and sustainable devices. The work is internally assessed by teachers and externally moderated by Cambridge, accounting for 25% of the total mark.
项目范围从自动驾驶车辆、桥梁模型到电子气象站和可持续设备。该作业由教师进行内部评估，并由剑桥进行外部审核，占总分的 25%。
8. Assessment Format and Weighting | 评估形式与权重
All three written papers last two hours and carry 80 marks each. They feature a mix of structured questions, data-response tasks and extended writing. The personal investigation is also marked out of 80. Each component is equally weighted at 25%. There is no tiering; all candidates sit the same papers.
所有三份笔试时长均为两小时，满分各 80 分。题型包括结构化问题、数据回答任务和扩展写作。个人探究的满分也是 80 分。每个组件权重均等，各占 25%。不设分级，所有考生完成相同的试卷。
| Component | Marks | Duration | Weighting |
|---|---|---|---|
| 1: Principles | 80 | 2 h | 25% |
| 2: Applications | 80 | 2 h | 25% |
| 3: Systems | 80 | 2 h | 25% |
| 4: Investigation | 80 | N/A | 25% |
9. Mathematical Skills and Tools | 数学技能与工具
Pre-U Engineering assumes a strong A-Level Mathematics background. Students are expected to be confident with algebra, trigonometry, calculus (differentiation and integration), vectors, matrices and statistics. These tools are applied to model physical systems, optimise designs and analyse experimental data.
Pre-U 工程要求具备扎实的 A-Level 数学基础。学生应熟练运用代数、三角学、微积分（微分和积分）、向量、矩阵和统计学。这些工具用于对物理系统建模、优化设计和分析实验数据。
For instance, simple harmonic motion is described by x = A sin(ω t + φ), and energy dissipation often involves exponential decay functions. Regular practice with mathematical modelling is essential for success across all components.
例如，简谐运动由 x = A sin(ω t + φ) 描述，而能量耗散常涉及指数衰减函数。在所有组件中，定期进行数学建模练习是取得成功的关键。
10. How to Succeed in Pre-U Engineering | 如何在 Pre-U 工程中取得成功
Success demands more than just memorising formulas. Engage actively with real engineering case studies from textbooks and websites. Build simple prototypes at home to develop hands-on intuition. When revising, practise past papers under timed conditions, and always link theory to practical examples. Keep a well-organised logbook for the personal investigation, documenting every design iteration and test result.
成功不仅仅需要记忆公式。要积极研读课本和网站上的真实工程案例。在家制作简单的原型以培养动手直觉。复习时，在计时条件下练习往年试卷，并始终将理论与实际例子相联系。为个人探究项目准备一本条理清晰的日志，记录每一次设计迭代和测试结果。
Time management is key, because the linear nature of the course means that content from Components 1-3 is examined at the very end. Start early to build deep understanding, and seek help from teachers or online communities when concepts become challenging.
时间管理是关键，因为课程的线性特性意味着组件 1-3 的内容到最后才进行考核。尽早开始学习以建立深厚的理解，并在概念变得困难时向老师或在线社区寻求帮助。
11. Further Study and Career Opportunities | 深造与职业机会
Cambridge Pre-U Engineering is highly regarded by universities, particularly for undergraduate courses in mechanical, civil, electrical, aerospace and general engineering. The personal investigation provides an excellent talking point for university interviews and personal statements, demonstrating independent research capability. Many students also progress to degree apprenticeships, combining work and study.
剑桥 Pre-U 工程受到大学的高度认可，尤其是对机械、土木、电气、航空航天和通用工程等本科课程。个人探究为大学面试和个人陈述提供了绝好的话题，体现出独立研究能力。许多学生也会选择学位学徒制，将工作与学习相结合。
