欢迎来到 Year 8 AQA 计算机暑期预习指南。本衔接课程旨在帮助你巩固 Year 7 的关键概念，并提前了解即将在 Year 8 学到的主题。无论你是想加深对计算思维的理解、提高编程技能，还是想探索计算机和网络的工作原理，这篇资源都将提供清晰、循序渐进的指导。让我们让这个夏天既有趣又高效，使你带着信心和好奇心步入 Year 8。
1. What is Computational Thinking? | 什么是计算思维？
Computational thinking is a problem-solving approach that uses concepts from computer science. It involves four key techniques: decomposition (breaking a problem down into smaller parts), pattern recognition (spotting similarities and trends), abstraction (focusing on the important information only, ignoring irrelevant detail), and algorithm design (creating a step-by-step plan to solve the problem). These skills are essential not only for programming but also for everyday tasks like planning a journey or organising a school project.
计算思维是一种运用计算机科学概念来解决问题的方法。它包括四个核心技巧：分解（将问题拆解成更小的部分）、模式识别（发现相似性与趋势）、抽象（只关注重要信息，忽略无关细节）和算法设计（创建逐步计划以解决问题）。这些技能不仅对编程至关重要，对规划行程或组织学校项目等日常任务也同样重要。
For example, if you are asked to design a simple game, you would use decomposition to split the task into characters, controls, scoring and backgrounds. Pattern recognition could help you reuse successful game mechanics from games you have played. Abstraction allows you to ignore the colour of a button and focus on its function. Finally, algorithm design gives you the exact sequence of events that make the game work. Practising these mental processes over the summer will sharpen your logical thinking and prepare you for the computational challenges ahead.
例如，如果让你设计一个简单游戏，你会用分解把任务拆分为角色、控制、计分和背景。模式识别帮你复用你玩过的游戏中成功的机制。抽象让你忽略按钮的颜色而专注其功能。最后，算法设计给出让游戏运行起来的确切事件序列。整个夏天练习这些思维过程，将磨练你的逻辑思维，为接下来的计算挑战做好准备。
2. Understanding Algorithms and Flowcharts | 理解算法与流程图
An algorithm is a precise set of instructions that leads to a desired outcome. It can be expressed in plain English, as pseudocode or visually through a flowchart. In Year 8, you will be expected to read, interpret and create simple algorithms using standard flowchart symbols: an oval for start/end, a rectangle for a process, a diamond for a decision, and a parallelogram for input/output. Flowcharts help you visualise the flow of logic before you write any code.
算法是一组精确的指令，能导向期望的结果。它可以用平实的英语、伪代码或通过流程图直观地表达。在 Year 8，你需要用标准流程图符号去阅读、解释和创建简单的算法：椭圆表示开始/结束，矩形表示过程，菱形表示决策，平行四边形表示输入/输出。流程图帮助你在编写任何代码前将逻辑流程可视化。
Let's consider a morning routine algorithm: start, check if it is a school day (decision); if yes, pack your bag and have breakfast; if no, sleep in. A flowchart would make this sequence crystal clear. Try drawing a flowchart for making a cup of tea or choosing what to wear based on the weather. Remember that each step must be precise and unambiguous – a computer cannot guess what you mean.
让我们考虑一个早晨例行算法：开始，检查是否是上学日（决策）；如果是，收拾书包和吃早餐；如果不是，睡个懒觉。流程图会让这个序列一目了然。尝试为泡一杯茶或根据天气选择穿什么绘制流程图。记住，每一步都必须精确且无歧义——计算机无法猜测你的意思。
3. Introduction to Programming with Python | Python 编程入门
Python is one of the most popular programming languages and is widely used in AQA Computer Science. If you have previously used block-based tools like Scratch, Python will feel more text-oriented but much more powerful. The key concepts you will practise include variables, data types (integers, strings, floats), input and output, conditional statements (if, elif, else) and loops (while, for). By writing small programs over the summer, you will become comfortable with syntax and error messages.
Python 是最流行的编程语言之一，在 AQA 计算机科学中被广泛使用。如果你之前用过像 Scratch 这样的积木式工具，Python 会感觉更面向文本但也强大得多。你将练习的关键概念包括变量、数据类型（整数、字符串、浮点数）、输入与输出、条件语句（if、elif、else）和循环（while、for）。通过在暑假编写一些小程序，你会逐渐熟悉语法和错误信息。
A simple starting project could be a number guessing game: the program picks a random number, and the player has to guess it, receiving hints like 'too high' or 'too low'. This will let you practise generating random numbers, using a while loop and comparing values. Type the code yourself – it is the best way to learn.
一个简单的起步项目可以是猜数字游戏：程序随机选一个数字，玩家去猜，并收到“太高”或“太低”的提示。这将让你练习生成随机数、使用 while 循环以及比较数值。自己动手输入代码——这是最佳的学习方式。
import random secret = random.randint(1, 100) guess = 0 while guess != secret: guess = int(input("Guess a number between 1 and 100: ")) if guess > secret: print("Too high!") elif guess < secret: print("Too low!") print("You got it!")
4. Data Representation: Binary and Beyond | 数据表示：二进制及以上
Computers store all data as binary – a system using only 0s and 1s. In Year 8, you will deepen your understanding of binary representation, including how to convert between binary and denary (base-10), and how binary is used to represent text (using ASCII), images (pixels) and sound (sampling). Knowing why computers use binary helps you appreciate the underlying logic of all digital devices.
计算机将所有数据存储为二进制——只用 0 和 1 的系统。在 Year 8，你将加深对二进制表示的理解，包括如何在二进制和十进制（基数为 10）之间转换，以及二进制如何表示文本（使用 ASCII）、图像（像素）和声音（采样）。了解计算机为何使用二进制有助于你领会所有数字设备背后的逻辑。
es are 2⁷ (128), 2⁶ (64), 2⁵ (32), 2⁴ (16), 2³ (8), 2² (4), 2¹ (2), 2⁰ (1). Practise converting your age or house number into binary. You should also understand that adding two binary numbers follows simple rules like 1+1=10 (carry 1). These skills will be built upon when you study hexadecimal later in the year.
一个 8 位二进制数，例如 01001011，可以通过将出现 1 的位值相加来转换为十进制：64 + 8 + 2 + 1 = 75。位值依次为 2⁷ (128)、2⁶ (64)、2⁵ (32)、2⁴ (16)、2³ (8)、2² (4)、2¹ (2)、2⁰ (1)。练习将你的年龄或门牌号转换成二进制。你还应该明白，两个二进制数相加要遵循简单的规则，如 1+1=10（进位 1）。这些技能将在你本学年稍后学习十六进制时得到进一步发展。
5. Computer Systems: Hardware and Software | 计算机系统：硬件与软件
A computer system consists of both hardware (the physical components you can touch) and software (the programs that run on the hardware). Core hardware includes the CPU (central processing unit), which executes instructions; RAM (random access memory), which stores data temporarily; storage devices like hard drives and SSDs for permanent data; and input/output devices such as keyboards, mice, monitors and printers. Understanding how these parts work together is fundamental to diagnosing problems and making informed choices about technology.
计算机系统由硬件（你能触碰到的物理组件）和软件（在硬件上运行的程序）共同构成。核心硬件包括执行指令的 CPU（中央处理器）、临时存储数据的 RAM（随机存取存储器）、像硬盘和固态硬盘这样用于永久存储的存储设备，以及键盘、鼠标、显示器和打印机等输入/输出设备。理解这些部件如何协同工作，是诊断问题和做出明智技术选择的基础。
The CPU follows a cycle called fetch-decode-execute. It fetches an instruction from memory, decodes it to understand what needs to be done, and then executes it. This happens billions of times per second. Over summer, try labelling the parts of a computer diagram or opening an old desktop (if safe) to see the components. You will also learn the difference between system software (like the operating system) and application software (like a word processor).
CPU 遵循一个称为“取指-译码-执行”的循环。它从内存中取出一条指令，译码以理解需要做什么，然后执行它。这个过程每秒发生数十亿次。暑假期间，尝试给计算机结构图的各部分贴上标签，或者（在确保安全的情况下）打开一台旧台式机看看各种组件。你还将学习系统软件（如操作系统）和应用软件（如文字处理软件）之间的区别。
6. Networks and the Internet | 网络与互联网
Computer networks allow devices to communicate and share resources. In Year 8, you will study LANs (local area networks) and WANs (wide area networks), network topologies such as star and bus, and the hardware needed like routers, switches and network interface cards. You will also explore how the internet works, including the role of protocols such as TCP/IP and HTTP, IP addresses and domain name servers (DNS).
计算机网络让设备能够通信和共享资源。在 Year 8，你将学习 LAN（局域网）和 WAN（广域网），星型和总线型等网络拓扑结构，以及所需硬件，如路由器、交换机和网络接口卡。你还将探索互联网的工作原理，包括 TCP/IP 和 HTTP 等协议的角色，IP 地址和域名服务器（DNS）。
A simple way to visualise a star topology is to imagine a central switch with cables running to each device – like the hub of a bicycle wheel. If one cable fails, only that device is affected. The bus topology, by contrast, has all devices connected along a single cable. Recognising the advantages and disadvantages of each will be important in your assessments. Try mapping out your home network: identify the router, connected devices and whether you use Wi-Fi or Ethernet cables.
想象星型拓扑的一个简单方式，是把中央交换机想象成连接每台设备的电缆中心——如同自行车轮的轴。如果一根电缆出故障，只有那台设备受影响。相反，总线型拓扑把所有设备都连接在同一条电缆上。认识到每种拓扑的优缺点对评估很重要。试着画出你的家庭网络：找出路由器、连接的设备以及你使用的是 Wi-Fi 还是网线。
7. Digital Safety and Cyber Security | 数字安全与网络安全
As you spend more time online, understanding how to protect yourself and your data becomes crucial. This topic covers threats like malware (viruses, worms, ransomware), phishing scams, social engineering and password security. You will learn about preventative measures such as firewalls, antivirus software, encryption and the importance of regular software updates. Being digitally literate includes knowing how to identify fake news and safeguard your digital footprint.
随着你上网时间越来越多，了解如何保护自己和数据变得至关重要。本主题涵盖恶意软件（病毒、蠕虫、勒索软件）、网络钓鱼诈骗、社会工程以及密码安全等威胁。你将学习防火墙、防病毒软件、加密等预防措施，以及定期更新软件的重要性。具备数字素养还包括懂得如何识别假新闻和保护你的数字足迹。
A strong password should be long, contain a mix of upper and lower case letters, numbers and symbols, and should not include personal information like your name or birthdate. Try creating a memorable but strong password using a passphrase, such as 'BlueFrog!Jump$Over2Moon'. Also, never share your passwords and always log out from shared devices. Discuss these habits with your family to build a safer online environment at home.
一个强密码应该较长，包含大小写字母、数字和符号的混合，并且不应包含姓名或生日等个人信息。尝试用口令短语创建一个易记但强壮的密码，例如 'BlueFrog!Jump$Over2Moon'。此外，绝不要分享密码，在共用设备上要始终登出。与家人讨论这些习惯，在家中营造更安全的在线环境。
8. Creative Projects: Using Micro:bit | 创意项目：使用 Micro:bit
The BBC micro:bit is a pocket-sized computer that introduces you to physical computing. With its LED display, buttons, sensors and Bluetooth connectivity, you can create interactive projects that combine hardware and software. Many AQA schools use the micro:bit to teach programming in an engaging, hands-on way. Summer is a brilliant time to experiment with simple circuits and block-based or Python programming on the micro:bit.
BBC micro:bit 是一款口袋大小的计算机，为你引入实体计算。借助它的 LED 显示屏、按钮、传感器和蓝牙连接，你可以创建结合硬件与软件的交互项目。许多 AQA 学校用 micro:bit 以引人入胜的动手方式教授编程。夏季是试验简单电路和在 micro:bit 上尝试积木式或 Python 编程的绝佳时机。
Start with a digital dice: when you shake the micro:bit, it displays a random number between 1 and 6. This project reinforces variables, random numbers and conditional logic. You can then extend it to a step counter or a simple thermometer using the built-in temperature sensor. The MakeCode editor at makecode.microbit.org allows you to drag and drop blocks or switch to Python to see the equivalent text code. Documenting your projects in a summer journal will also strengthen your computational thinking skills.
从数字骰子开始：当你摇晃 micro:bit，它显示 1 到 6 之间的一个随机数。这个项目强化了变量、随机数和条件逻辑。你之后可以将其扩展为计步器或使用内置温度传感器的简易温度计。MakeCode 编辑器（makecode.microbit.org）允许你拖放积木块，或切换到 Python 查看等效的文本代码。在暑期日志中记录项目还会增强你的计算思维技巧。
9. Problem Solving and Debugging Skills | 问题解决与调试技巧
No programmer writes perfect code on the first try. Debugging – finding and fixing errors – is an essential skill. Errors can be syntax errors (typos), logic errors (the program runs but gives wrong results) or runtime errors (crashes). Developing a systematic approach: read the error message carefully, check the line it refers to, use print statements to inspect variable values, and test small sections of code at a time. These habits will save you hours of frustration.
没有哪个程序员第一次就能写出完美代码。调试——查找并修正错误——是一项基本技能。错误可能是语法错误（拼写错误）、逻辑错误（程序运行但结果错误）或运行时错误（崩溃）。培养一种系统方法：仔细阅读错误消息，检查它指向的行，使用 print 语句检查变量值，并一次测试一小段代码。这些习惯将为你省去大量沮丧时间。
Try breaking a working program on purpose and then fixing it. For example, remove a colon after an if statement or misspell a variable name, then use the error clues to restore the code. You can also swap programs with a friend and exchange debugging challenges. Remember: a bug is just a puzzle to be solved, and every one you fix makes you a better programmer.
尝试故意破坏一段可用的程序然后修复它。例如，删除 if 语句后的冒号，或者拼错变量名，然后利用错误线索恢复代码。你也可以和朋友交换程序，进行调试挑战。记住：bug 只是一个待解的谜题，你每修复一个都让自己成为更优秀的程序员。
10. Computational Thinking Challenge: Puzzles and Games | 计算思维挑战：谜题与游戏
Making computational thinking fun is easy with puzzles and logic games. Activities like cracking ciphers, solving sudoku, playing chess or completing online challenges on platforms such as Blockly Games or Bebras sharpen pattern recognition, decomposition and algorithm design. Set aside a regular 'puzzle time' each week where you tackle a new challenge away from the screen or on a puzzle app.
通过谜题和逻辑游戏，让计算思维变得有趣很容易。破解密码、完成数独、下国际象棋或在 Blockly Games 或 Bebras 等平台完成在线挑战，都能磨练模式识别、分解和算法设计。每周安排固定的“谜题时间”，在远离屏幕的地方或用谜题应用解决一个新挑战。
For example, try to write an algorithm that escapes a simple maze using only commands like 'move forward', 'turn left' and 'turn right'. Test it out on graph paper. Then introduce a loop to repeat a sequence of moves. Such unplugged activities build the mental muscles you will rely on when coding. Invite a family member to solve your maze algorithm – can they follow it exactly to succeed?
例如，尝试写一个只用“前进”、“左转”和“右转”指令穿越简单迷宫的算法。在方格纸上测试它。接着引入循环来重复一系列移动。这样的不插电活动能锻炼你日后编程时依赖的脑力。邀请一位家人按照你的迷宫算法走——他们能精确遵循并成功吗？
11. Exploring Artificial Intelligence (Introduction) | 探索人工智能（入门）
Artificial intelligence (AI) is an exciting field that overlaps with computer science. While Year 8 does not require deep AI knowledge, understanding the basic concepts will spark curiosity. AI systems learn from data, recognise patterns and make decisions. Examples include recommendation engines on streaming sites, voice assistants, and simple chatbots. You can experiment with free, educational AI tools that use machine learning to sort images or predict text.
人工智能（AI）是一个与计算机科学相交的激动人心的领域。尽管 Year 8 不要求深入的 AI 知识，但理解基本概念会激发好奇心。AI 系统从数据中学习，识别模式并做出决策。例子包括流媒体网站的推荐引擎、语音助手和简单的聊天机器人。你可以使用免费的、教育性的 AI 工具做实验，这些工具运用机器学习来分类图像或预测文本。
A key takeaway is that AI is not magic – it relies on algorithms and vast amounts of data. Discuss with your family the ethical implications, such as bias in data and privacy. Keeping an 'AI in daily life' diary for a week, noting every time an app makes a suggestion, will help you see computer science in action. This awareness will serve you well as technology continues to evolve.
一个关键点是，AI 并非魔法——它依赖算法和海量数据。与家人讨论其伦理影响，如数据中的偏见和隐私问题。花一周时间写一本“生活中的 AI”日记，记录每次应用做出推荐的情况，将帮助你看到计算机科学的实际应用。随着技术不断演进，这种意识会让你受益匪浅。
