1. Understanding the Question | 理解题目

Before writing, read the question carefully and identify the command words. Common command words include ‘describe’, ‘explain’, ‘discuss’, ‘evaluate’, and ‘compare’. ‘Describe’ asks you to state the facts, ‘explain’ requires reasons and how things work, while ‘discuss’ or ‘evaluate’ expects you to present both sides and give a conclusion. Underline the key terms such as ‘star network’, ‘encryption’, or ‘ethical issues’ so you know exactly what technical content to cover.

在写作之前，仔细阅读题目并识别指令词。常见的指令词包括”describe”（描述）、”explain”（解释）、”discuss”（讨论）、”evaluate”（评价）和”compare”（比较）。”Describe”要求陈述事实，”explain”需要给出原因和工作原理，而”discuss”或”evaluate”则期望你呈现正反两面并给出结论。划出关键术语，比如”star network”（星形网络）、”encryption”（加密）或”ethical issues”（伦理问题），这样你就能准确知道自己需要涵盖哪些技术内容。

2. Planning Your Answer | 规划你的答案

Spend the first 2–3 minutes scribbling a quick plan on the exam paper. A simple mind‑map or bullet‑point list will organise your thoughts and prevent you from going off‑topic. For a discuss question, create two columns: one for advantages, one for disadvantages. For an explain question, jot down the sequence of steps or the cause‑and‑effect relationships. This plan ensures your essay has a logical flow and covers all required aspects.

花前2-3分钟在试卷上快速草拟一个计划。一个简单的思维导图或要点列表可以整理你的思路，避免偏题。对于讨论类问题，创建两栏：一栏写优点，一栏写缺点。对于解释类问题，记下步骤的顺序或因果关系。这个计划确保你的文章具有逻辑流畅性，并涵盖所有必要的方面。

3. Crafting an Introduction | 撰写引言

Your first sentence should directly rephrase the question and state your intention. For example: ‘A star network topology has several advantages and disadvantages that affect its performance and reliability in modern computer systems.’ Avoid simply copying the question. Then briefly outline what your essay will cover, such as ‘This essay will discuss the central dependency, scalability, and cost factors before reaching a balanced conclusion.’ Keep the introduction to two or three sentences.

你的第一句话应该直接改写题目并表明你的意图。例如：”星形网络拓扑结构有几个优点和缺点，这些优缺点影响了它在现代计算机系统中的性能和可靠性。”（A star network topology has several advantages and disadvantages…）避免直接照抄题目。然后简要概述你的文章将涵盖的内容，例如”本文将讨论中心依赖性、可扩展性和成本因素，然后得出一个平衡的结论。”引言保持两到三句话即可。

4. Developing Main Body Paragraphs | 展开主体段落

Each body paragraph should discuss one clear point using the PEEL structure: Point, Evidence, Explanation, and Link. Start with a topic sentence that introduces the point (e.g., ‘One major advantage of a star topology is that if one cable fails, only the connected device is affected.’). Follow with evidence or a specific example (e.g., ‘In a school computer lab, a broken cable to one machine will not disrupt others.’). Then explain how or why this matters technically, and finally link back to the question or to the next paragraph. Aim for two to three well‑developed paragraphs.

每个主体段落应该使用PEEL结构讨论一个明确的观点：观点(Point)、证据(Evidence)、解释(Explanation)和衔接(Link)。以主题句开头，引出观点（例如：”星形拓扑结构的一个主要优点是，如果一根电缆发生故障，只有连接的设备会受到影响。”）。接着提供证据或具体例子（例如：”在学校的计算机实验室，一根连接到某台机器的电缆损坏不会中断其他机器。”）。然后从技术角度解释这是如何或为何重要的，最后回扣题目或过渡到下一段。目标是写出两到三个充分展开的段落。

5. Using Technical Terminology Accurately | 准确使用技术术语

Examiners look for precise and correct use of computer science vocabulary. Terms like ‘protocol’, ‘bandwidth’, ‘encryption’, ‘volatile memory’, ‘packet switching’, and ‘logic gate’ must be spelled correctly and used in the right context. Avoid vague language such as ‘thing’ or ‘stuff’. If you define a term, do it concisely: ‘Encryption is the process of converting plaintext into ciphertext to prevent unauthorised access.’ This demonstrates subject mastery and earns high marks for technical detail.

考官看重准确和正确使用计算机科学词汇。像”protocol”（协议）、”bandwidth”（带宽）、”encryption”（加密）、”volatile memory”（易失性存储器）、”packet switching”（分组交换）和”logic gate”（逻辑门）等术语必须拼写正确并用于恰当的语境。避免使用”thing”或”stuff”等模糊语言。如果要定义一个术语，请简洁地表达：”加密是将明文转换为密文以防止未授权访问的过程。”这展示了你对学科的掌握，并因技术细节而获得高分。

6. Providing Relevant Examples | 提供相关示例

Concrete examples bring your essay to life and show that you can apply theory to real‑world scenarios. For a question on network security, you might mention ‘using a firewall to filter incoming and outgoing traffic based on predefined rules, such as in a school network to block social media sites.’ Examples do not need to be long — one or two well‑chosen instances per paragraph are sufficient. Always link the example back to the technical point you are making.

具体的例子使你的文章生动起来，并且表明你可以将理论应用于现实场景。对于网络安全方面的问题，你可以提到”使用防火墙根据预定义的规则过滤进出流量，例如在学校网络中屏蔽社交媒体网站。”例子不需要很长——每段一两个精选案例就足够了。始终将例子与你正在阐述的技术要点联系起来。

7. Discussing Advantages and Disadvantages | 讨论优缺点

When a question asks you to ‘discuss’ or ‘evaluate’, you must present both sides. Use connective phrases to structure your argument clearly: ‘On the one hand, … On the other hand, …’, ‘A significant benefit is … However, a drawback is …’ or ‘While this offers …, it also introduces …’. After presenting both sides, weigh the evidence and provide a reasoned judgement. For instance, ‘Despite the higher initial setup cost, the improved fault tolerance of a star network makes it the preferred choice for critical business environments.’

当题目要求”discuss”（讨论）或”evaluate”（评价）时，你必须呈现两个方面。使用连接性短语来清晰地组织你的论证：”On the one hand, … On the other hand, …”（一方面…另一方面…）、”A significant benefit is … However, a drawback is …”（一个显著益处是…然而一个缺点是…）或”While this offers …, it also introduces …”（虽然这提供了…，但也引入了…）。呈现两面之后，权衡证据并给出有理有据的判断。例如：”尽管初始设置成本较高，但星形网络改进的容错能力使其成为关键业务环境的首选。”

8. Drawing a Conclusion | 得出结论

Your conclusion should summarise the main arguments without introducing new information. Begin with a signal phrase such as ‘In conclusion,’ or ‘To sum up,’. Then briefly restate the key points made in the body paragraphs and give a final evaluation or recommendation. For example: ‘Overall, while the star topology incurs a higher cable cost and relies on a central device, its ease of maintenance and scalability make it ideal for modern LANs.’ A strong conclusion ties the essay together and reinforces your answer.

你的结论应该总结主要论点，不引入新信息。以信号短语开头，如”In conclusion,”或”To sum up,”。然后简要重述主体段落中的关键点，并给出最终评价或建议。例如：”总体而言，尽管星形拓扑结构产生更高的电缆成本并依赖于中心设备，但它易于维护和可扩展性使其成为现代局域网的理想选择。”一个有力的结论将全文连成一体，巩固你的答案。

9. Managing Time in the Exam | 管理考试时间

Extended response questions should not consume too much time. Allocate approximately 12–15 minutes for a 6‑mark essay and 15–18 minutes for an 8‑mark question. Use the first 3 minutes for planning and the last 2 minutes for proofreading. Stick to your plan and avoid writing excessively long introductions. If you are running out of time, at least jot down key points in bullet form — many exam boards award marks for correct technical content even if the prose is incomplete.

扩展回答题不应占用过多时间。一道6分的作文题大约分配12-15分钟，一道8分的题分配15-18分钟。用前3分钟规划，最后2分钟校对。坚持按照计划写作，避免写出过长的引言。如果时间不够了，至少以要点形式写下关键点——即使散文不完整，许多考试局也会因为正确的技术内容而给分。

10. Common Pitfalls to Avoid | 要避免的常见陷阱

One common mistake is failing to address the command word — describing when you should be evaluating, for example. Another is repeating the same point in different words instead of developing new ideas or providing depth. Many students also neglect to use technical language, which is essential for high marks. Finally, avoid writing an answer that ends abruptly; always include a short conclusion, even if it is just one sentence, to give your essay a finished feel.

一个常见的错误是未能回应指令词——比如你应该评价时却只是描述。另一个错误是用不同的措辞重复同一个观点，而不是展开新的想法或提供深度。许多学生还忽略了使用技术语言，而这对高分至关重要。最后，避免写出突然结束的答案；一定要包含一个简短的结论，哪怕只有一句话，以给你的文章一种完整的感觉。

11. Practising with Past Papers | 通过历年真题练习

Nothing builds confidence like practising with real past paper questions. Use the mark schemes to understand what examiners expect for each level. For example, a mark scheme might award 1 mark for a valid advantage, 1 for a valid disadvantage, and 2 marks for a reasoned conclusion. Write timed essays and then compare them with model answers. Identify gaps in your knowledge and keep a glossary of key terms that you tend to misspell or misuse.

没有什么比用真实的历年真题练习更能建立信心了。利用评分方案来了解考官对每个等级的要求。例如，一个评分方案可能为一个有效的优点给1分，为一个有效的缺点给1分，为一个有理有据的结论给2分。计时写作然后与标准答案进行比较。找出你在知识上的差距，并保留一份你经常拼错或误用的关键术语词汇表。

12. Sample Essay Template Applied | 应用示例文章模板

The table below shows how to structure a complete answer for the question: ‘Discuss the advantages and disadvantages of using a star network topology.’ (8 marks)

下面的表格展示了如何为问题：”讨论使用星形网络拓扑结构的优缺点。” (8分) 构建一个完整的答案结构。

Section	Content Guide
Introduction	Define a star topology: ‘A star network connects all nodes to a central switch or hub using dedicated cables.’ State that it has both benefits and limitations.
Body Paragraph 1 (Advantage)	Point: Independent cable failures. Evidence: ‘If one workstation’s cable breaks, the rest of the network continues to function.’ Explanation: This improves reliability compared to a bus topology. Link: ‘Therefore, fault isolation is straightforward.’
Body Paragraph 2 (Advantage)	Point: Easy to add or remove devices. Example: ‘In an office, a new computer can be connected to the central switch without disrupting network traffic.’
Body Paragraph 3 (Disadvantage)	Point: Central point of failure. ‘If the central switch fails, the entire network goes down.’ Use comparison: ‘This is a single-point-of-failure risk not present in a mesh topology.’
Body Paragraph 4 (Disadvantage)	Point: Higher cabling cost and port requirement. ‘Each device needs its own cable to the hub, increasing initial setup cost and complexity.’
Conclusion	Summarise and evaluate: ‘Despite the risks associated with a central node and greater cabling, the star topology’s reliability and maintainability make it the dominant choice for wired LANs today.’

Using this template, you can adapt the structure to any discuss/evaluate question by simply changing the technical content. Practise writing your own response in full prose, ensuring you include both technical depth and careful evaluation.

使用这个模板，你可以通过简单地改变技术内容来适应任何讨论/评价类问题。练习用完整的散文写你自己的回答，确保你同时包含技术深度和仔细的评价。
