1. Why Summer Prep Matters for Year 7 Computing? | 为什么暑期预习对七年级计算机课程很重要？
Starting a new subject in a new school can feel daunting. When you prepare over the summer, you reduce first-day nerves by already knowing the basic vocabulary and ideas. This head start lets you focus on solving problems and being creative instead of worrying about catching up.
在一所新学校开始一门新学科可能会让人感到不安。如果你利用暑假进行预习，提前熟悉了基本词汇和概念，开学第一天的紧张感就会大大降低。这样的提前准备能让你专注于解决问题和发挥创意，而不必担心跟不上进度。
Computing is not just about coding; it teaches you to think logically and break big problems into smaller steps. By exploring these skills early, you will discover how computers work and how you can use them to build your own games, animations and tools. This early taste often sparks a lasting passion for technology.
计算机科学不仅仅是编程，它还教会你逻辑思考，把大问题拆分成小步骤。提前探索这些技能，你会了解计算机是如何工作的，以及如何利用它们制作自己的游戏、动画和工具。这种早期的体验常常会点燃对科技的持久热情。
2. Understanding the OCR KS3 Computing Framework | 了解OCR KS3计算机课程框架
OCR’s Key Stage 3 computing curriculum is built around three main strands: Computer Science, Information Technology and Digital Literacy. Computer Science covers programming and how hardware and software work. Information Technology focuses on using digital tools to create and manage content. Digital Literacy teaches you to use technology safely and responsibly.
OCR的KS3计算机课程围绕三大主线构建：计算机科学、信息技术和数字素养。计算机科学涵盖编程以及硬件和软件的工作原理。信息技术侧重于使用数字工具创建和管理内容。数字素养则教你安全、负责任地使用技术。
In Year 7, you will encounter topics such as the basics of algorithms, simple programming in block-based environments like Scratch or text-based languages like Python, understanding computer components, and learning about online safety. The course is designed to be hands-on, with lots of practical projects and collaborative tasks.
在七年级，你将接触到算法基础、使用Scratch等积木式环境或Python等文本语言进行简单编程、了解计算机组件以及学习网络安全等主题。课程设计注重实践，包含大量动手项目和合作任务。
3. Getting to Know Computer Hardware | 认识计算机硬件
Hardware refers to the physical parts of a computer system that you can touch. The central processing unit (CPU) is the brain of the computer, carrying out instructions. Random access memory (RAM) holds data and programs currently in use, but loses its contents when the power is off. Storage devices like hard disk drives (HDD) and solid-state drives (SSD) keep information permanently.
硬件指的是计算机系统中可以触摸到的物理部件。中央处理器（CPU）是计算机的大脑，负责执行指令。随机存取存储器（RAM）保存当前正在使用的数据和程序，但断电后内容会丢失。硬盘驱动器（HDD）和固态驱动器（SSD）等存储设备则会永久保存信息。
- CPU: processes instructions billions of times per second
- RAM: short-term memory, speeds up multitasking
- Storage: HDD, SSD – keeps files, apps and the operating system
- Input devices: keyboard, mouse, touchscreen, microphone
- Output devices: monitor, speakers, printer
- CPU: 每秒处理数十亿条指令
- RAM: 短期记忆，加快多任务处理速度
- 存储设备: HDD、SSD——保存文件、应用程序和操作系统
- 输入设备: 键盘、鼠标、触摸屏、麦克风
- 输出设备: 显示器、扬声器、打印机
4. Software and Operating Systems | 软件与操作系统
Software is the set of instructions that tells hardware what to do. System software includes the operating system (OS), which manages hardware, runs applications and provides a user interface. Examples include Windows, macOS, ChromeOS and Linux. Application software lets users perform specific tasks, such as word processors, web browsers and games.
软件是指挥硬件工作的一组指令。系统软件包括操作系统（OS），它管理硬件、运行应用程序并提供用户界面。常见的操作系统有Windows、macOS、ChromeOS和Linux。应用软件则让用户完成特定任务，例如文字处理软件、网页浏览器和游戏。
Understanding the role of the OS helps you appreciate why different devices behave differently. The OS handles file management, memory allocation and security. When you save a document or install a new app, you are interacting with the operating system. During summer prep, try exploring the settings and file explorer on your home computer to see these concepts in action.
了解操作系统的作用有助于你理解不同设备为何表现各异。操作系统负责文件管理、内存分配和安全。当你保存文档或安装新应用时，就是在与操作系统交互。在暑期预习中，可以尝试探索家中电脑的设置和文件资源管理器，观察这些概念的实际运作。
5. Introduction to Programming Concepts | 编程概念入门
Programming is giving a computer a series of instructions to complete a task. The three fundamental building blocks are sequence, selection and iteration. Sequence means doing steps in order. Selection uses conditions like ‘if’ to make decisions. Iteration involves loops that repeat actions.
编程就是给计算机一系列指令来完成任务。三个基本构建块是顺序、选择和迭代。顺序就是按次序执行步骤。选择用“如果”这样的条件来做决定。迭代则是通过循环重复执行操作。
In Year 7 you might start with a block language like Scratch, where you snap colourful blocks together. For example, to make a cat move across the screen:
when green flag clicked
forever
move 10 steps
if on edge, bounce
在七年级，你可能会从Scratch这样的积木式语言开始，通过拼接彩色积木来编程。例如，让一只猫在屏幕上移动：
当绿旗被点击
重复执行
移动 10 步
碰到边缘就反弹
You may also write simple text-based code. A Python program to greet a user could look like this:
name = input(‘What is your name? ‘)
print(‘Hello ‘ + name)
你也可能会编写简单的文本代码。一个用Python问候用户的程序可以这样写：
name = input(‘你叫什么名字？ ‘)
print(‘你好 ‘ + name)
6. Data Representation: How Computers Store Information | 数据表示：计算机如何存储信息
All data inside a computer is stored as binary – combinations of only 0s and 1s. A single binary digit is called a bit. Eight bits make one byte. A byte can represent a character using codes like ASCII. For example, the capital letter ‘A’ is 01000001 in binary, which equals 65 in decimal.
计算机内部的所有数据都以二进制形式存储——只有0和1的组合。一个二进制位称为比特。八个比特组成一个字节。一个字节可以使用类似ASCII的编码来表示一个字符。例如，大写字母’A’的二进制是01000001，十进制是65。
| Unit | Symbol | Number of Bytes |
|---|---|---|
| Kilobyte | KB | 2¹⁸ bytes (1024) |
| Megabyte | MB | 2²⁸ bytes (~1 million) |
| Gigabyte | GB | 2³⁸ bytes (~1 billion) |
| 单位 | 符号 | 字节数 |
|---|---|---|
| 千字节 | KB | 2¹⁰ 字节 (1024) |
| 兆字节 | MB | 2²⁰ 字节 (~1百万) |
| 吉字节 | GB | 2³⁰ 字节 (~10亿) |
Understanding binary and byte sizes helps you make sense of storage limits and file sizes. It also lays the foundation for later topics such as image representation (pixels) and sound sampling. Try converting small decimal numbers to binary as a logic puzzle – a perfect summer brain teaser.
理解二进制和字节大小有助于你理解存储限制和文件大小。这也为后续的图像表示（像素）和声音采样等主题打下基础。试着将小十进制数字转换为二进制，当作一个逻辑谜题——这是一个绝佳的暑期脑筋急转弯。
7. Networks and the Internet | 网络与互联网
A network is two or more computers connected together to share resources. A local area network (LAN) covers a small geographical area, like a school or home. The internet is a global wide area network (WAN) that connects millions of networks worldwide using protocols like TCP/IP.
网络是两台或多台连接在一起的计算机，用于共享资源。局域网（LAN）覆盖一个小范围的地理区域，如学校或家庭。互联网则是一个全球性的广域网（WAN），通过TCP/IP等协议将全球数百万个网络连接起来。
Key network hardware includes routers, which direct data traffic, and switches, which connect devices within a LAN. Data is sent in small packets that travel along different routes and are reassembled at the destination. The World Wide Web, which you browse, is a service that runs on the internet, using HTTP to deliver web pages.
关键的网络硬件包括引导数据流量的路由器和在局域网内连接设备的交换机。数据以小数据包的形式发送，这些数据包沿不同路径传输并在目的地重新组装。你浏览的万维网是运行在互联网上的一项服务，它使用HTTP协议传送网页。
8. E-safety and Digital Citizenship | 网络安全与数字公民
Staying safe online is a huge part of Year 7 computing. Strong passwords, privacy settings and the ability to spot phishing attempts protect your personal data. Never share your full name, address or school online without a trusted adult’s permission. A good password uses a mix of uppercase, lowercase, numbers and symbols, and is at least eight characters long.
保持网络安全是七年级计算机课程的重要组成部分。强密码、隐私设置以及识别网络钓鱼尝试的能力可以保护你的个人数据。未经可信赖的成人允许，绝不在网上分享你的全名、地址或学校。一个好的密码应包含大小写字母、数字和符号，长度至少为八个字符。
Digital citizenship means being respectful and responsible online. Cyberbullying, spreading rumours or sharing hurtful comments can have serious consequences. Always think before you post – once something is online, it can be very difficult to remove. Your digital footprint is the trail of information you leave behind; keep it positive and professional.
数字公民意味着在网上保持尊重和负责任。网络欺凌、散布谣言或分享伤害性评论可能会带来严重后果。发帖前请三思——一旦信息发布到网上，就很难删除。你的数字足迹是你留下的信息痕迹；请保持积极正面。
9. Computational Thinking Skills | 计算思维技能
Computational thinking is the problem-solving approach at the heart of computing. It involves four pillars: decomposition (breaking a problem into smaller parts), pattern recognition (spotting similarities), abstraction (focusing on important information only) and algorithm design (creating step-by-step solutions).
计算思维是计算机科学核心的解决问题方法。它包含四大支柱：分解（将问题拆分成更小的部分）、模式识别（发现相似之处）、抽象（只关注重要信息）和算法设计（创建分步解决方案）。
- Decomposition: When making a sandwich, list ingredients, then steps for preparation.
- Pattern Recognition: Notice that drawing a square and a rectangle share repeating side patterns.
- Abstraction: When designing a game, ignore the colour of the character’s shoes and focus on its movement rules.
- Algorithm Design: Write precise instructions for a robot to navigate a maze.
- 分解: 做三明治时，列出食材，再写出制作步骤。
- 模式识别: 注意画正方形和矩形时共享重复的边模式。
- 抽象: 设计游戏时，忽略角色鞋子的颜色，专注于运动规则。
- 算法设计: 为机器人写出穿越迷宫的精确指令。
These skills are not only for computing; they help you think clearly in maths, science and everyday life. Over the summer, practise by solving puzzles or breaking down daily routines into simple steps.
这些技能不仅用于计算机科学，还能帮助你在数学、科学和日常生活中清晰思考。暑假期间，可以通过解谜或者把日常流程拆解成简单步骤来练习。
10. Hands-on Project: Build a Simple Program | 动手项目：制作一个简单的程序
Nothing beats the excitement of creating your own program. Using Scratch (free at scratch.mit.edu), you can build a simple interactive story or game in an afternoon. Start by adding a sprite, then program its behaviour using blocks from the scripting area.
没有什么比自己制作程序更令人兴奋了。使用Scratch（在scratch.mit.edu免费使用），一个下午你就可以做出一个简单的互动故事或游戏。先添加一个角色，然后用脚本区的积木为其编写行为。
Project idea: a chasing game. Choose a cat sprite and a mouse sprite. When the green flag is clicked, the cat follows the mouse pointer forever. The mouse moves randomly around the stage. If the cat touches the mouse, play a sound and end the game. You will use event, motion, control and sensing blocks – all core programming concepts.
项目创意：追逐游戏。选择一个猫咪角色和一个老鼠角色。点击绿旗后，猫咪不停地跟随鼠标指针移动，老鼠在舞台上随机移动。如果猫咪碰到老鼠，就播放音效并结束游戏。你将用到事件、运动、控制、侦测等积木——这些全部是核心编程概念。
Challenge yourself further by adding a score variable that increases every second the mouse avoids capture. Experimenting like this strengthens your understanding of variables, loops and conditions in a creative way.
进一步挑战自己：添加一个分数变量，老鼠每躲过一秒就加分。这样的尝试能让你在创造中加深对变量、循环和条件的理解。
11. Tips for a Smooth Transition into Year 7 | 顺利过渡到七年级的提示
Organisation is your best friend. Set up a dedicated folder for computing notes, and bookmark useful websites like BBC Bitesize and Code.org. Spend 15–20 minutes a few times a week exploring these resources during summer; short, regular practice is far more effective than last-minute cramming.
有条理是最好的伙伴。为计算机笔记设立一个专门的文件夹，并收藏BBC Bitesize和Code.org等实用网站。暑假期间每周抽出几次时间，每次15–20分钟探索这些资源；短时间、有规律的练习远比临时抱佛脚有效。
Stay curious and don’t be afraid to make mistakes – debugging is an essential part of programming. If your Scratch project doesn’t work, read the blocks carefully, check the sequence and ask a family member to look with you. Asking ‘why’ and ‘what if’ will turn you into a confident problem solver.
保持好奇心，不要害怕犯错——调试是编程至关重要的部分。如果你的Scratch项目不运行，仔细阅读积木、检查顺序，或请家人一起看看。多问“为什么”和“如果……会怎样”，这会让你成为一个自信的问题解决者。
