In Year 7 Cambridge Computer Science, you will often be asked to write short papers or reports to explain concepts, describe projects, or present your findings. This article provides a clear framework you can follow every time, along with a complete sample paper to illustrate how each part should look. By learning this structure early, you will build strong academic writing skills for future IGCSE and A Level studies.
在 Year 7 剑桥计算机科学课程中，你经常需要撰写短篇论文或报告，来解释概念、描述项目或展示你的发现。本文提供一个清晰的写作框架，并配上一篇完整的范文，展示每个部分应如何呈现。尽早学会这个结构，将为未来的 IGCSE 和 A Level 学习打下坚实的学术写作基础。
1. Why Write a Computer Science Paper? | 为什么撰写计算机科学论文？
Writing a paper is not just about getting a grade; it helps you organise your thoughts, check your understanding, and communicate ideas logically. In Computer Science, clear communication is as important as coding or problem-solving. When you write about a topic like binary numbers or algorithms, you deepen your own knowledge and learn to explain technical ideas to others.
撰写论文不仅仅是为了成绩；它能帮助你整理思路、检验理解，并有逻辑地传达观点。在计算机科学中，清晰的沟通与编程或解决问题同样重要。当你围绕二进制数或算法等主题进行写作时，你会加深自己的理解，并学会向他人解释技术思想。
2. Understanding the Assignment Requirements | 理解作业要求
Before you start writing, read the task sheet carefully. Look for keywords such as 'describe', 'explain', 'compare', or 'evaluate'. These words tell you what type of answer is expected. Also check the length (e.g. 500–800 words), whether you need to include diagrams, and how many sources you should reference. A common Year 7 task might ask you to 'Explain how a computer stores text using ASCII and provide examples.'
动笔之前，仔细阅读任务说明。注意诸如“描述”“解释”“比较”或“评价”等关键词，它们能告诉你需要给出哪种类型的回答。同时检查字数要求（例如 500–800 字）、是否需要加图，以及应引用多少资料来源。Year 7 常见的题目可能会要求“解释计算机如何使用 ASCII 存储文本，并举例”。
3. Choosing a Manageable Topic | 选择一个可操作的主题
If you are free to choose your own topic, pick one that is focused and interesting to you. Instead of 'Computers', try 'How input devices send data to the CPU'. A narrow topic allows you to explore it in depth without running out of things to say. Brainstorm a few ideas, and then select the one that you can support with examples from your class notes or simple research.
如果可以自由选题，请选择一个集中且你感兴趣的主题。不要选“计算机”，试试“输入设备如何向 CPU 发送数据”。一个集中的主题能让你深入探索，不会无话可说。先头脑风暴几个想法，然后选出那个你能用课堂笔记或简单研究中的例子来支撑的主题。
4. Conducting Simple Research | 进行简单的研究
Use your textbook, reliable educational websites, and class handouts to gather information. As you read, write down key points in your own words – never copy sentences directly. For a Year 7 paper, two or three sources are usually enough. Keep a list of the sources you use so you can cite them later.
利用课本、可靠的教育网站和课堂讲义来收集信息。阅读时，用自己的话记下要点——切勿直接照抄句子。对于 Year 7 的论文，通常两到三个来源就足够了。保留一份你使用过的来源列表，以便日后引用。
5. The Standard Structure of a Paper | 论文的标准结构
A well-organised Computer Science paper follows a logical order: Title, Abstract, Introduction, Body (split into sections with subheadings), Conclusion, and References. This structure guides your reader from the main idea to the supporting details and finally to a summary. Even a short Year 7 report should use these elements to stay clear and professional.
一篇组织良好的计算机科学论文遵循逻辑顺序：标题、摘要、引言、主体（用子标题分成若干小节）、结论和参考文献。这个结构引导读者从主要观点到支撑细节，最后到总结。即使是简短的 Year 7 报告，也应使用这些要素，以保持清晰和专业。
6. Crafting an Effective Title and Abstract | 撰写有效的标题与摘要
The title should reflect your paper's exact content. For example, 'How Binary Numbers Represent Text' is better than 'Computers and Numbers'. An abstract is a short paragraph (around 50–80 words) that summarises your whole paper. Write the abstract last, after the rest of the paper is complete, so that it accurately reflects the content.
标题应准确反映论文内容。例如“二进制数如何表示文本”比“计算机与数字”更好。摘要是简要概括全文的一小段话（大约 50–80 词）。应最后撰写摘要，在论文其他部分完成之后再动笔，这样摘要才能准确反映内容。
7. Writing a Strong Introduction | 撰写强有力的引言
The introduction should hook your reader's attention and state what the paper will cover. Start with a general fact or question, then narrow down to your specific topic. For example: 'Every time you type a letter, your computer converts it into a number. This process is called encoding. In this paper, I will explain how ASCII encoding works and show three examples.'
引言应吸引读者注意，并说明论文将涵盖哪些内容。从一个普遍的事实或问题入手，然后集中到你的具体主题。例如：“每当你打出一个字母，计算机就会将其转换成一个数字。这个过程叫做编码。在本文中，我将解释 ASCII 编码如何工作，并展示三个例子。”
8. Building Body Paragraphs | 构建主体段落
Each body paragraph should focus on one main idea. Use the PEEL method: Point, Evidence, Explanation, Link. Start with a clear statement (Point), back it up with a fact or diagram (Evidence), explain what this evidence shows (Explanation), and connect it back to the main question (Link). For instance, when explaining ASCII, one paragraph might focus on uppercase letters and their ASCII codes.
每个主体段落应集中讨论一个主要观点。使用 PEEL 方法：观点、证据、解释、联系。先给出清晰的陈述（观点），然后用事实或图表来支撑（证据），接着解释证据说明了什么（解释），最后将其与主要问题联系起来（联系）。例如，解释 ASCII 时，某一段可以聚焦于大写字母及其 ASCII 码。
9. Incorporating Evidence and Diagrams | 加入证据与图表
Evidence strengthens your argument. For a Computer Science paper, you can include tables of binary conversions, simple flowcharts, or labelled screenshots. Always refer to the diagram in your text, e.g. 'As shown in Figure 1, the letter 'A' is represented by 65 in decimal and 0100 0001 in binary.' Place diagrams close to the paragraph that discusses them, and give each a brief caption.
证据能增强你的论证。对于计算机科学论文，你可以添加二进制转换表、简单的流程图或标注过的屏幕截图。务必在文中提及该图表，例如“如图 1 所示，字母‘A’用十进制 65 和二进制 0100 0001 表示”。将图表放在讨论它们的段落附近，并为每张图添加简短的标题。
10. Writing a Conclusion | 撰写结论
The conclusion should summarise the main points and restate the answer to the original question without introducing new information. It often begins with a phrase like 'In conclusion' or 'To summarise'. Then briefly revisit the key ideas from your body paragraphs and end with a final thought about why the topic matters in the wider world of computing.
结论应总结主要观点并重申对原始问题的回答，但不引入新信息。通常以“综上所述”或“概括来说”开头。然后简要回顾主体段落的关键思想，最后以该主题在更广阔的计算世界为何重要的思考作结。
11. Citing Sources and Creating a Bibliography | 引用来源与创建参考书目
Even in Year 7, it is good practice to list the sources you used. Use a consistent format such as: Author, Title, Date, URL. For example: 'BBC Bitesize, Data Representation, 2024, www.bbc.co.uk/bitesize/...'. In the text, you can briefly mention the source: 'According to BBC Bitesize, ASCII uses 7 bits...' This builds academic honesty and prepares you for higher grades.
即使在 Year 7，列出你所使用的来源也是一个良好习惯。使用统一的格式，如：作者、标题、日期、网址。例如：“BBC Bitesize, 数据表示, 2024, www.bbc.co.uk/bitesize/...”。在正文中，你可以简要提及来源：“根据 BBC Bitesize，ASCII 使用 7 位……”。这有助于培养学术诚信，为更高年级的学习做好准备。
12. Sample Paper: 'What is an Algorithm?' | 范文：“什么是算法？”
The following sample paper follows the framework exactly. Read it carefully to see how all the sections fit together. Note the use of a clear title, a short abstract, a focused introduction, well-structured body paragraphs, a concise conclusion, and a simple reference list.
下面的范文严格遵循上述框架。仔细阅读，观察各个部分如何组合在一起。注意它使用了清晰的标题、简短的摘要、聚焦的引言、结构良好的主体段落、简洁的结论以及简单的参考列表。
Title: What is an Algorithm? A Beginner's Guide
标题：什么是算法？入门指南
Abstract
摘要
This paper explains the basic concept of an algorithm in Computer Science. It provides a definition, gives everyday and computational examples, and discusses why algorithms are important. The paper uses a simple recipe and a number-searching algorithm to show how precise instructions solve problems.
本文解释计算机科学中算法的基本概念。它给出定义，提供日常生活和计算方面的例子，并讨论算法为何重要。本文用一个简单的食谱和一个数字搜索算法，展示精确的指令如何解决问题。
1. Introduction
1. 引言
Algorithms are everywhere, from the apps on your phone to the way you tie your shoelaces. In computing, an algorithm is simply a set of step-by-step instructions for completing a task. This paper will define what an algorithm is, show examples you might see in daily life, and explain one simple computer algorithm. By the end, you will understand why algorithms are the building blocks of all software.
算法无处不在，从手机上的应用程序到你系鞋带的方式。在计算领域，算法简单来说就是一套完成任务的步骤说明。本文将定义什么是算法，展示你可能在日常生活中见到的例子，并解释一个简单的计算机算法。读完后，你将明白为什么算法是所有软件的基础构件。
2. Definition of an Algorithm
2. 算法的定义
An algorithm is a finite sequence of well-defined instructions to solve a problem or perform a computation. It must be clear, unambiguous, and produce the correct output for every valid input. For instance, a cooking recipe is an algorithm: it lists ingredients and gives step-by-step cooking instructions to produce a dish.
算法是一个有限的、定义明确的指令序列，用于解决问题或执行计算。它必须清晰、无歧义，并对每个有效输入都产生正确的输出。例如，烹饪食谱就是一个算法：它列出食材，并给出分步烹饪说明来制作一道菜。
3. Everyday Examples of Algorithms
3. 算法的日常例子
You use algorithms all the time without realising it. A morning routine (wake up, brush teeth, get dressed, have breakfast) is an algorithm. A set of instructions for assembling a toy is an algorithm. Even a simple game like 'guess the number' involves a logical method – you can follow the 'binary search' algorithm by guessing the middle value each time to find the answer quickly.
你经常在不知不觉中使用算法。早晨的例行活动（起床、刷牙、穿衣服、吃早餐）就是一个算法。组装玩具的一套说明也是算法。甚至像“猜数字”这样简单的游戏也涉及逻辑方法——你可以每次猜中间值，遵循“二分查找”算法来快速找到答案。
4. A Computational Example: Linear Search
4. 一个计算示例：线性搜索
In computing, a very simple algorithm is linear search. Suppose you have a list of numbers: 3, 7, 12, 9, 5. You want to find if the number 9 is in the list. The linear search algorithm looks at each item one by one from left to right until it finds the target or reaches the end. The steps are: 1) Start at the first element. 2) If the current element equals the target, stop and report success. 3) Otherwise move to the next element. 4) Repeat until the target is found or the list ends.
在计算中，一个非常简单的算法是线性搜索。假设你有一列数字：3, 7, 12, 9, 5。你想知道数字 9 是否在列表中。线性搜索算法从左到右逐个查看列表中的每一项，直到找到目标或到达末尾。步骤是：1) 从第一个元素开始。2) 如果当前元素等于目标值，停止并报告成功。3) 否则移动到下一个元素。4) 重复直到找到目标或列表结束。
For the list above, the algorithm checks 3 (no), 7 (no), 12 (no), then 9 (yes) and stops. This algorithm is easy to understand and works on any small list.
对于上面的列表，算法检查 3（否），7（否），12（否），然后 9（是）并停止。这个算法易于理解，适用于任何小型列表。
5. Why Algorithms Matter
5. 为什么算法很重要
Algorithms are the core of programming. Every software application uses them to sort data, search information, make decisions, and display graphics. By designing efficient algorithms, computer scientists can make programs run faster and use less memory. Understanding algorithms also helps you think logically and solve problems in a structured way.
算法是编程的核心。每个软件应用程序都使用它们来排序数据、搜索信息、做出决策和显示图形。通过设计高效的算法，计算机科学家可以让程序运行得更快、占用更少的内存。理解算法还能帮助你进行逻辑思考，并以结构化的方式解决问题。
6. Conclusion
6. 结论
In summary, an algorithm is a step-by-step plan for solving a problem. We encounter them in daily routines and in the digital world. Simple algorithms like linear search show how computers process information methodically. As you continue studying Computer Science, you will learn many more algorithms and begin to design your own.
总结来说，算法是解决问题的分步计划。我们在日常生活和数字世界中都会遇到它们。像线性搜索这样简单的算法展示了计算机如何有条理地处理信息。随着你继续学习计算机科学，你将学习更多算法并开始设计自己的算法。
