欢迎来到激动人心的工程世界！这个暑期衔接课程旨在让你在七年级SQA工程学习中领先一步。你将探索工程师的工作内容、学习基础概念，并培养能够让你第一学期更轻松、更有趣的技能。把这视为你在新学年开始前打下坚实基础的“工具箱”。
1. What is Engineering? | 什么是工程？
Engineering is the application of scientific and mathematical principles to design, build, and improve structures, machines, and systems. It transforms ideas into real solutions that make our lives safer, healthier, and more convenient.
工程是运用科学与数学原理来设计、建造和改进结构、机器及系统。它将创意转化为切实的解决方案，让我们的生活更安全、更健康、更便利。
Engineers are problem-solvers who use creativity and analysis. Whether it is constructing a bridge that can withstand earthquakes or developing a new mobile phone app, engineering touches every part of modern life.
工程师是使用创造力和分析技能的问题解决者。无论是建造能抵御地震的桥梁，还是开发新的手机应用程序，工程触及现代生活的方方面面。
2. Types of Engineering | 工程的类型
Engineering is a broad field with many specialisms. The main branches include civil, mechanical, electrical, and chemical engineering, but modern disciplines like software and biomedical engineering are growing rapidly.
工程是一个拥有众多专业领域的广阔领域。主要分支包括土木工程、机械工程、电气工程和化学工程，但像软件工程和生物医学工程这样的现代学科正在迅速发展。
Civil engineers deal with infrastructure such as roads, bridges, and water supply. Mechanical engineers focus on machines and moving parts, while electrical engineers work with circuits and power systems. Chemical engineers transform raw materials into useful products like fuels and plastics.
土木工程师负责道路、桥梁和供水等基础设施。机械工程师专注于机器和运动部件，电气工程师则处理电路与电力系统。化学工程师将原材料转化为燃料和塑料等有用产品。
3. The Engineering Design Process | 工程设计流程
Every engineering project follows a structured approach called the design process. It begins with identifying a problem or need, followed by research, brainstorming solutions, selecting the best idea, building a prototype, and testing it.
每个工程项目都遵循一个称为设计流程的结构化方法。它从确定问题或需求开始，然后进行研究、头脑风暴解决方案、选择最佳想法、构建原型并进行测试。
The process is iterative – engineers often go back to improve their design based on test results. In Year 7, you will learn to apply simple versions of this cycle to hands-on challenges, building your design thinking skills from day one.
这个过程是迭代的——工程师通常会根据测试结果返回去改进设计。在七年级，你将学习对这一循环的简单版本进行实操挑战，从第一天起就培养你的设计思维方式。
4. Basic Materials in Engineering | 工程中的基础材料
Selecting the right material is crucial in engineering. Common categories include metals (steel, aluminium), polymers (plastics, nylon), ceramics (brick, glass), and composites (carbon fibre, concrete). Each has unique properties such as strength, flexibility, and resistance to heat.
选择合适的材料在工程中至关重要。常见类别包括金属（钢、铝）、聚合物（塑料、尼龙）、陶瓷（砖、玻璃）和复合材料（碳纤维、混凝土）。每种材料都有独特的性质，如强度、柔韧性和耐热性。
You will learn to compare materials using terms like ‘hardness’, ‘ductility’, and ‘density’. A simple activity to try this summer is to collect household objects made of different materials and identify why each material was chosen for its purpose.
你将学习用“硬度”、“延展性”和“密度”等术语来比较材料。今年夏天可以尝试一个简单活动：收集由不同材料制成的家用物品，并确认为什么每种材料被选作用于其目的。
5. Simple Machines and Mechanisms | 简单机械与机构
Simple machines are the building blocks of more complex devices. They include the lever, pulley, wheel and axle, inclined plane, wedge, and screw. These mechanisms change the direction or magnitude of a force, making work easier.
简单机械是复杂装置的基本构件。它们包括杠杆、滑轮、轮轴、斜面、楔子和螺旋。这些机构改变力的方向或大小，使做功更容易。
The mechanical advantage (MA) of a simple machine can be calculated. For a lever, MA is roughly the ratio of the effort arm length to the load arm length. The formula is shown below:
简单机械的机械效益 (MA) 是可以计算的。对于杠杆，MA 约等于动力臂长度与阻力臂长度的比值。其公式如下：
MA = Effort Arm / Load Arm
Understanding MA helps engineers design tools that multiply force, such as a crowbar or a pair of scissors. Try practising with a ruler and a pencil as a fulcrum over the holidays.
理解机械效益有助于工程师设计可放大力力的工具，如撬棍或剪刀。假期里不妨试试用一把尺子和一支铅笔作为支点来练习。
6. Forces and Motion | 力与运动
Forces are pushes or pulls that can cause objects to accelerate, slow down, or change shape. In engineering, you will study balanced and unbalanced forces, friction, and Newton’s laws of motion at an introductory level.
力是能使物体加速、减速或改变形状的推或拉。在工程学中，你将从入门层面学习平衡力与不平衡力、摩擦力以及牛顿运动定律。
Speed, distance, and time are linked by a simple equation. If you measure how far an object moves and how long it takes, you can calculate its average speed:
速度、距离和时间由一个简单公式关联。如果测量物体移动的距离和所用的时间，就能计算出它的平均速度：
v = d / t
where v is speed, d is distance, and t is time. A fun summer experiment is to time a toy car rolling down a ramp and calculate how changing the ramp height affects its speed.
其中 v 代表速度，d 代表距离，t 代表时间。一个有趣的夏季实验是，让一辆玩具小车从斜坡上滑下并计时，计算改变斜坡高度会如何影响其速度。
7. Technical Drawing and Sketching | 技术制图与速写
Being able to communicate ideas clearly is essential. Engineers use technical drawings, including orthographic projections (front, side, top views) and isometric sketches, to show the shape and dimensions of an object accurately.
清晰地传达想法至关重要。工程师使用技术图纸，包括正交投影（前视图、侧视图、俯视图）和等轴测草图，来准确展现物体的形状和尺寸。
During summer, you can practise by drawing everyday items like a mug or a toy block from three different angles. Use a ruler, keep lines neat, and label dimensions. This will build your confidence before you start formal drawing lessons.
暑假期间，你可以通过从三个不同角度绘制水杯或积木等日常物品来进行练习。使用尺子，保持线条整洁，并标注尺寸。这将让你在正式开始制图课程之前建立信心。
8. Measurement and Units | 测量与单位
Accurate measurement is the backbone of engineering. You will work primarily with the International System of Units (SI). The table below shows the base quantities and their units that you will use most often.
精确测量是工程的基石。你将主要使用国际单位制 (SI)。下表显示了你最常使用的基本量及其单位。
| Quantity / 量 | Unit Name / 单位名称 | Symbol / 符号 |
|---|---|---|
| Length / 长度 | metre / 米 | m |
| Mass / 质量 | kilogram / 千克 | kg |
| Time / 时间 | second / 秒 | s |
| Force / 力 | newton / 牛顿 | N |
| Energy / 能量 | joule / 焦耳 | J |
Practise reading rulers, weighing scales, and stopwatches over the break. Being comfortable with metric units will give you a real advantage in the workshop.
假期里可以练习阅读标尺、体重秤和秒表。对公制单位得心应手，将使你在实践车间里获得真正的优势。
9. Safety in Engineering | 工程安全
Safety is the number one priority in any engineering environment. Before you enter a workshop, you must understand and follow safety rules to protect yourself and others. Safety glasses, proper footwear, and tying back long hair are basic requirements.
安全是任何工程环境中的第一要务。进入车间前，你必须理解并遵守安全规则，以保护自己和他人。护目镜、合适的鞋子和束起长发是基本要求。
Key safety rules to remember include:
需要记住的关键安全规则包括：
- Always listen to your teacher’s instructions. / 始终听从老师的指导。
- Wear personal protective equipment (PPE) correctly. / 正确佩戴个人防护装备 (PPE)。
- Never run or fool around in the workshop. / 切勿在车间内奔跑或打闹。
- Keep your work area clean and tidy. / 保持工作区域干净整洁。
- Report any damaged tools or equipment immediately. / 立即报告任何损坏的工具或设备。
Developing a strong safety habit from the start will make all your practical projects safer and more productive.
从一开始就养成良好的安全习惯，将使你所有的实践项目更安全且更富有成效。
10. Problem-Solving Skills | 问题解决能力
At its heart, engineering is about finding solutions. You will learn to break down a problem into smaller parts, think creatively, and test different approaches. This method is often called ‘systems thinking’.
工程的核心在于寻找解决方案。你将学习将问题分解为更小的部分、进行创造性思考并测试不同的方法。这种方法通常称为“系统思维”。
A simple way to practise is to follow the ‘Identify, Plan, Do, Review’ cycle. First, identify exactly what the problem is. Next, plan a possible solution. Then, carry out your plan and finally review the result. This cycle can be applied to anything from fixing a wobbly table leg to designing a paper bridge.
一个简单的练习方法是遵循“识别、计划、执行、检查”循环。首先，准确识别问题是什么。接下来，计划一个可能的解决方案。然后执行你的计划，最后检查结果。这个循环可以用于从修理摇晃的桌腿到设计纸桥的任何事情。
Over the summer, challenge yourself to solve a small practical problem every week using this cycle. Document your process in a notebook.
暑假期间，挑战自己每周用这个循环解决一个小型实际问题。把你的过程记录在笔记本上。
11. Your Summer Prep Plan | 你的暑期预习计划
To make the most of this bridging course, create a simple weekly plan. Spend 1–2 hours twice a week exploring one topic from this article. For example, Week 1 could focus on materials observation, while Week 2 looks at forces with the toy car experiment.
为了充分利用这个衔接课程，制定一个简单的每周计划。每周花两次，每次1–2小时，探索本文中的一个主题。例如，第一周专注于材料观察，第二周则用玩具小车实验研究力。
Keep a summer engineering journal with sketches, measurements, and notes. This will not only reinforce your learning but also serve as a great reference when you start Year 7. Most importantly, stay curious and have fun exploring how things work!
准备一本暑期工程日记，用来记录草图、测量数据和笔记。这不仅能巩固所学，还能在你升入七年级时成为极好的参考资料。最重要的是，保持好奇心，享受探索事物运作过程的乐趣！
