1. Why Essay Writing Matters in Computer Science | 为什么计算机科学需要论文写作
Computer science is not only about coding; it also involves explaining how technology works, evaluating its impact, and making ethical decisions. Learning to write well helps you communicate your computational thinking and develop arguments supported by facts. For Year 7 assessments, your teacher may ask you to write a short essay on topics such as online safety, digital citizenship, or the history of computing.
计算机科学不仅仅是编程，还包括解释技术如何运作、评估其影响以及做出伦理决策。学好写作能帮助你传达计算思维，并用事实来支撑论点。在七年级的评估中，老师可能会要求你就网络安全、数字公民或计算历史等主题撰写一篇短文。
2. Choosing a Topic | 选题
A good topic should be interesting to you and relevant to the AQA computer science curriculum. Start by brainstorming areas you have studied, such as algorithms, data representation, e-safety, or artificial intelligence. Narrow your focus to a specific question, for example, 'Is screen time harmful to teenagers?' rather than a broad title like 'Technology'.
好的选题应当让你感兴趣，并且与AQA计算机科学课程相关。先头脑风暴你学过的领域，比如算法、数据表示、网络安全或人工智能。然后把焦点缩小到一个具体问题上，例如“屏幕时间对青少年有害吗？”，而不是像“科技”这样宽泛的题目。
3. Research and Note-taking | 研究并做笔记
Before writing, gather information from reliable sources such as textbooks, school online libraries, or teacher-recommended websites. As you read, write down key facts, statistics, and quotations on separate cards or in a digital document. Remember to record where each piece of information came from so you can cite it later.
在动笔之前，先从可靠的来源（如教科书、学校在线图书馆或老师推荐的网站）收集信息。一边阅读，一边将关键事实、数据和引语记录在单独的卡片或电子文档中。记得记下每条信息的出处，以便日后引用。
4. Essay Structure Overview | 论文结构概述
A well-organised essay helps the reader follow your argument. The standard structure for a short computer science essay includes: an introduction that presents your main idea; three or four body paragraphs each discussing one key point; a conclusion that summarises your argument and gives a final thought. You may also include a title and a list of references at the end.
条理清晰的论文能让读者跟上你的论证。计算机科学短论文的标准结构包括：引出主要观点的引言部分；三到四个各讨论一个关键点的正文段落；总结论点并给出最终思考的结论部分。最后还可以附上标题和参考文献列表。
| Section | Purpose |
| Title | Grabs attention and shows the topic |
| Introduction | States your argument and outlines the essay |
| Body paragraphs | Provide evidence and explain your points |
| Conclusion | Wraps up the discussion and reinforces your viewpoint |
| References | Lists sources used to avoid plagiarism |
中文说明：标题——吸引注意并点明主题；引言——陈述论点并概述文章；正文段落——提供证据并解释观点；结论——总结讨论并强化立场；参考文献——列出所用来源以避免抄袭。
5. Writing a Strong Introduction | 撰写有力的引言
Your introduction should hook the reader from the first sentence. You can start with a surprising fact, a question, or a short scenario. Then clearly state your thesis – the main argument your essay will prove. Finally, briefly indicate what your body paragraphs will cover. Keep the introduction to about three or four sentences for a Year 7 essay.
引言应当从第一句话就吸引住读者。你可以用一个令人惊讶的事实、一个问题或一个简短的情景开头。然后清楚地陈述你的论题——即文章将要证明的主要论点。最后，简要说明正文段落会涵盖哪些内容。七年级论文的引言保持在三到四句话左右即可。
Example opening: 'Every day, millions of people use the password "123456". But did you know hackers can crack such passwords in less than a second? This essay will argue that choosing strong passwords is one of the simplest yet most important ways to stay safe online. It will explore how passwords are attacked, what makes a password strong, and why this habit matters for everyone.'
示例开头：“每天都有数百万人使用密码‘123456’。但你知道黑客能在不到一秒内破解这类密码吗？本文将论证选择强密码是确保上网安全最简单、最重要的方法之一。文章将探讨密码如何被攻击、什么使密码强大，以及为什么这个习惯对每个人都至关重要。”
6. Developing Body Paragraphs | 撰写主体段落
Each body paragraph should focus on one clear idea. Use the PEEL structure: Point – state the idea; Evidence – give a fact, example, or statistic; Explanation – say how this supports your argument; Link – connect back to the thesis or to the next point. This keeps your writing logical and easy to follow.
每个正文段落应聚焦于一个清晰的观点。使用PEEL结构：观点——陈述想法；证据——给出事实、示例或数据；解释——说明这如何支持你的论点；连接——回扣论题或过渡到下一点。这会让你的写作逻辑清晰，易于理解。
For instance, a paragraph about password weakness could start: 'Weak passwords are dangerously easy to guess. Studies show that the top ten most common passwords include "password" and "qwerty". When users choose these, they essentially leave their accounts open to brute-force attacks, where automated software tries thousands of combinations per second. This shows that simplicity is a security risk, directly supporting the need for stronger habits.'
例如，关于密码弱点的段落可以这样开始：“弱密码很容易被猜出，危险重重。研究表明，最常见的十大密码包括‘password’和‘qwerty’。用户选择这些密码时，实际上就等于把账户敞开来面对暴力破解——自动化软件每秒能尝试成千上万种组合。这表明简单化正是一种安全风险，直接证明了养成更强习惯的必要性。”
7. Using Evidence and Examples | 使用证据与示例
Good essays rely on facts, not just opinions. When you make a claim, back it up with specific data or authoritative quotes. In computer science topics, you might use statistics from cybersecurity reports, real-life hacking incidents, or results from your own investigations. Always explain why the evidence matters, rather than dropping it in without comment.
优秀论文依赖事实，而不仅仅是个人看法。提出主张时，要用具体数据或权威引用加以支撑。在计算机科学主题中，你可以使用网络安全报告中的统计数据、真实的黑客事件或自己调查得出的结果。务必解释证据为何重要，而不是不加说明地堆砌。
8. Writing a Convincing Conclusion | 撰写有说服力的结论
The conclusion is your last chance to impress the reader. Restate your thesis in fresh words, summarise your main points without introducing new information, and end with a final thought that connects to the wider world or offers a call to action. Keep it concise – around three sentences is ideal for a Year 7 essay.
结论是你给读者留下印象的最后机会。用新的表述重申论题，总结要点但不引入新信息，并以联系现实世界或提出行动号召的结束语收尾。保持简洁——七年级论文以三句话左右为宜。
Sample conclusion: 'In conclusion, creating strong, unique passwords is a simple act that dramatically improves online safety. By avoiding common words and mixing characters, users can protect themselves from brute-force and dictionary attacks. Schools and families should make password education a priority so that everyone can build safer digital habits.'
结论示例：“总之，创建强并且独特的密码是种可以大幅提升网络安全的简单行为。通过避免常用词汇并混合字符，用户可以保护自己免受暴力破解和字典攻击。学校和家庭应将密码教育作为优先事项，让每个人都能养成更安全的数字习惯。”
9. Referencing and Avoiding Plagiarism | 参考文献与避免抄袭
Whenever you use someone else's idea or data, you must give credit. Plagiarism is a serious academic offence. In Year 7, a simple reference list at the end of your essay is enough. Write the author's name, the title of the source, and the date you accessed it. For websites, include the URL. Your teacher will show you the preferred style.
无论何时使用他人的观点或数据，都必须注明出处。抄袭是严重的学术不端。在七年级，论文末尾附上一个简单的参考文献列表就够了。写出作者姓名、资料名称以及你访问的日期。对于网站，要包含网址。老师会告诉你偏爱的格式。
Example entry: 'Symantec Corporation. Internet Security Threat Report. Accessed 12 March 2025. www.symantec.com/threatreport'
条目示例：“Symantec Corporation. Internet Security Threat Report. Accessed 12 March 2025. www.symantec.com/threatreport”

English Sample Essay
Title: Why Strong Passwords Matter
Every 39 seconds, a cyberattack occurs somewhere in the world (Clark, 2024). Often, these attacks succeed because people use weak passwords like 'password' or '123456'. This essay argues that creating strong passwords is essential for protecting personal information and should be taught from an early age. It will discuss the risks of weak passwords, the features of a secure password, and the long-term benefits of good password habits.
First, weak passwords open the door to unauthorised access. Hackers use programs called brute-force tools that try every possible combination until they guess correctly. A six-character lowercase password can be cracked in under ten minutes, whereas a twelve-character password with symbols and numbers could take centuries (Morgan, 2023). When a password is compromised, criminals can steal banking details, impersonate the victim, and even lock users out of their own accounts.
Second, a strong password follows simple rules: it is long, unique, and contains a mix of uppercase letters, lowercase letters, numbers, and symbols. Security experts recommend using passphrases – strings of random words like 'correct horse battery staple' – which are both memorable and much harder to crack than short, complex jumbles (Munroe, 2011). Additionally, never reuse the same password across different sites, because a breach on one service then exposes all others.
Finally, adopting strong password habits early builds a foundation for lifelong digital safety. Students who learn about password managers and two-factor authentication are more likely to safeguard their future online identities. Schools can reinforce this through workshops and simple challenges, such as checking how quickly a password can be guessed.
In conclusion, passwords are the first line of defence in the digital world. Using weak passwords invites attacks, while strong, well-managed passwords significantly reduce risk. Everyone, especially young learners, should be empowered to create secure passwords and understand why they matter. In the words of a cybersecurity campaign: 'Stop. Think. Connect.'

标题：为什么强密码很重要
每39秒，世界某处就会发生一次网络攻击（Clark, 2024）。这些攻击之所以得逞，往往是因为人们使用了如“password”或“123456”这样的弱密码。本文主张创建强密码对保护个人信息至关重要，并应从幼年就加以教育。文章将讨论弱密码的风险、安全密码的特征以及良好密码习惯的长期好处。
首先，弱密码为未经授权的访问打开了大门。黑客们使用称为暴力破解工具的程序，尝试所有可能的组合，直到猜中。一个六位全小写字母密码可在不到十分钟内被破解，而一个带有符号和数字的十二位密码则可能需要数百年才能破解（Morgan, 2023）。密码一旦泄露，犯罪分子就可能盗取银行信息、冒充受害者，甚至将用户锁在自家账户之外。
其次，强密码遵循简单规则：足够长、独一无二，并混合大写字母、小写字母、数字和符号。安全专家建议使用口令短语——像“正确的马电池钉书钉”这样一串随机单词——它们既容易记忆，又比短小复杂的乱码更难破解（Munroe, 2011）。此外，切勿在不同网站上重复使用同一密码，因为一个服务的数据泄露就会牵连所有其他账户。
最后，尽早养成强密码习惯能为终身的数字安全打下基础。了解密码管理器和双重认证的学生更有可能保护未来的在线身份。学校可以通过工作坊和小竞赛（比如检测密码被猜出的速度）来强化这一观念。
总之，密码是数字世界的第一道防线。使用弱密码会招致攻击，而妥善管理的强密码则能显著降低风险。每个人都应被赋予创建安全密码的能力并理解其重要性，尤其是年轻学习者。用网络安全宣传活动的口号来说：“停下来。想一想。再连接。”
