有效的沟通是工程学的核心。在 IGCSE 工程课程中，口语和听力技能不仅通过直接评估来考查，还体现在你解释设计、理解指令以及协作完成实践任务的能力上。本指南将详细解析考试要求与备考方法，重点涵盖技术词汇、清晰表达和积极倾听策略，帮助你在考场内外都能游刃有余。

1. Understanding the Assessment Format | 了解评估形式

The speaking and listening component in IGCSE Engineering often takes the form of a structured discussion or presentation about a given engineering problem. You may be asked to describe a manufacturing process, justify material choices or listen to a series of instructions and then carry out a practical task. The exam aims to test your ability to use technical English accurately and to respond appropriately to spoken information.

IGCSE 工程的口语与听力部分通常采用结构化讨论或围绕给定工程问题进行汇报的形式。你可能会被要求描述一个制造过程、论证材料选择，或者听取一系列指令后完成一项实践任务。考试旨在检验你准确使用技术英语的能力，以及恰当地回应口语信息的水平。

Typical tasks: individual presentation, paired discussion, listening to a technical briefing and answering questions.
典型任务： 个人展示、双人讨论、听取技术简报并回答问题。
Assessment criteria: fluency, pronunciation, range of technical vocabulary, comprehension accuracy, and interactive ability.
评估标准： 流利度、发音、技术词汇量、理解准确性以及互动能力。

2. Building an Engineering Vocabulary Bank | 建立工程词汇库

To speak confidently about engineering, you need a solid repertoire of subject-specific terms. Start by grouping vocabulary into categories such as materials (ferrous, non-ferrous, composite), processes (forging, casting, milling), properties (tensile strength, hardness, ductility) and tools (caliper, micrometer, lathe). Write down both the noun and the verb form where applicable, e.g. ‘to weld / welding’.

要自信地谈论工程话题，你需要扎实的专业词汇储备。首先将词汇按类别分组，例如材料（黑色金属、有色金属、复合材料）、工艺（锻造、铸造、铣削）、性能（抗拉强度、硬度、延展性）和工具（卡尺、千分尺、车床）。在适用的情况下，同时记下名词和动词形式，例如 ‘to weld / welding’。

Use flashcards with an image on one side and the English term plus definition on the other.
使用抽认卡，一面放图片，另一面写英语术语和定义。
Practice pronouncing multisyllabic technical words: ‘aluminium’ /ˌæl.jəˈmɪn.i.əm/, ‘thermoplastic’ /ˌθɜː.məʊˈplæs.tɪk/.
练习多音节技术单词的发音：’aluminium’ /ˌæl.jəˈmɪn.i.əm/，’thermoplastic’ /ˌθɜː.məʊˈplæs.tɪk/。
Keep a ‘Word of the Day’ diary, writing a sentence in an engineering context.
坚持做“每日一词”日记，写在工程语境中的句子。

3. Describing Processes Clearly | 清晰描述过程

When explaining a manufacturing or assembly process, structure your speech with sequence markers: first, next, then, after that, finally. Use the passive voice where appropriate to focus on the action rather than the doer, e.g. ‘The metal is heated until it becomes malleable.’ Avoid overly long sentences; break the process into distinct steps and speak at a measured pace.

在解释制造或装配过程时，用顺序连接词来组织你的发言：first, next, then, after that, finally。适当使用被动语态以突出动作本身而非执行者，例如 ‘The metal is heated until it becomes malleable.’ 避免过长的句子；将过程分解为清晰的步骤，并以平稳的语速表达。

English sequence marker	中文对照	Example
Initially / To begin with	最初 / 首先	Initially, a pattern is made from wood.
Subsequently	随后	Subsequently, the mould is filled with molten alloy.
At the final stage	在最后阶段	At the final stage, the casting is fettled and inspected.

4. Discussing Material Properties | 讨论材料性能

You must be able to compare and contrast materials in spoken English. Use comparative structures: ‘Steel is stronger than pure iron because of its carbon content.’ Quantify differences: ‘The compressive strength of concrete is approximately 25 N/mm², which is significantly lower than that of granite.’ Get comfortable with phrases like ‘high strength-to-weight ratio’, ‘resistance to corrosion’, and ‘thermal conductivity’.

你必须能用英语口语比较和对比材料。使用比较结构：’Steel is stronger than pure iron because of its carbon content.’ 量化差异：’The compressive strength of concrete is approximately 25 N/mm², which is significantly lower than that of granite.’ 熟练掌握 ‘high strength-to-weight ratio’（高比强度）、’resistance to corrosion’（耐腐蚀性）和 ‘thermal conductivity’（导热性）等短语。

Prepare a short spoken profile for common engineering materials: mild steel, brass, nylon, oak, and carbon fibre.
为常见工程材料准备简短的口语概述：低碳钢、黄铜、尼龙、橡木和碳纤维。
Use a Venn diagram to organise similarities and differences before speaking.
在发言前使用维恩图来梳理相似点和不同点。

5. Giving and Responding to Instructions | 发出与回应指令

Listening tasks often demand that you follow a sequence of technical instructions, for example, adjusting a machine setting or assembling a simple mechanism. Pay close attention to numerical values, safety warnings and order words. In your speaking, practice giving clear, unambiguous instructions using imperative verbs: ‘Secure the workpiece in the vice. Set the spindle speed to 1200 rpm. Engage the automatic feed and stand clear.’

听力任务常常要求你遵循一系列技术指令，例如调整机器设置或组装简单机构。要特别留意数值、安全警告和顺序词。在口语练习中，用祈使动词给出清晰、明确的指令：’Secure the workpiece in the vice. Set the spindle speed to 1200 rpm. Engage the automatic feed and stand clear.’

Shadowing exercise: listen to a recorded set of workshop instructions and repeat them aloud, mimicking intonation.
影子练习：听一段录制的车间指令并大声复述，模仿语音语调。
Practise with a partner – one gives instructions, the other draws or mimes the action.
与同伴练习——一人发指令，另一人画出或模拟动作。

6. Interpreting Technical Drawings and Schematics Aloud | 口头解释技术图纸与示意图

You may be asked to describe what you see in a sectional drawing or a circuit diagram. Learn the language of views: ‘plan view’, ‘front elevation’, ‘isometric projection’. Describe dimensions using ‘by’ and ‘times’, e.g. ‘The base plate measures 150 mm by 80 mm.’ For electrical schematics, use phrases like ‘normally open contact’, ‘relay coil’, ‘earth connection’.

你可能会被要求描述在剖面图或电路图中看到的内容。学习视图的语言：’plan view’（平面图）、’front elevation’（正视图）、’isometric projection’（等轴测投影）。用 ‘by’ 和 ‘times’ 描述尺寸，例如 ‘The base plate measures 150 mm by 80 mm.’ 对于电气原理图，使用 ‘normally open contact’（常开触点）、’relay coil’（继电器线圈）、’earth connection’（接地）等短语。

Keep a reference sheet of ISO drafting symbols and their English descriptions.
保存一张 ISO 制图符号及其英文描述的参考表。
Record yourself describing a mechanical assembly and play it back to check for accuracy and fluency.
录下自己描述机械装配的过程并回放，检查准确性和流利度。

7. Handling Numerical Data and Units in Speech | 口语中处理数值数据与单位

Engineering is quantitative, so speaking numbers correctly is essential. Pronounce units in full: ‘newton metre’ not ‘N m’, ‘megapascal’ not ‘MPa’. Use spoken forms for decimals and fractions: ‘0.75 millimetres’ is said as ‘nought point seven five millimetres’, and ‘1/2 inch’ as ‘half an inch’. When presenting tolerances, state the nominal size and the limits, e.g. ‘The shaft diameter is 20 mm with a tolerance of plus zero point one, minus zero.’

工程是定量的，因此正确说出数字至关重要。单位要完整读出来：’newton metre’ 而不是 ‘N m’，’megapascal’ 而不是 ‘MPa’。小数和分数使用口语形式：’0.75 millimetres’ 读作 ‘nought point seven five millimetres’，’1/2 inch’ 读作 ‘half an inch’。在介绍公差时，说出公称尺寸和极限值，例如 ‘The shaft diameter is 20 mm with a tolerance of plus zero point one, minus zero.’

Practise reading tables of material properties aloud: ‘Young’s modulus of copper is one hundred and ten gigapascals.’
练习大声读出材料性能表：’Young’s modulus of copper is one hundred and ten gigapascals.’
Be familiar with multiplier prefixes: kilo, mega, milli, micro.
熟悉倍数前缀：kilo、mega、milli、micro。

8. Active Listening Strategies for Technical Briefings | 技术简报的积极倾听策略

During a listening task, you will hear a technical briefing only once or twice. Train yourself to identify the speaker’s main purpose, whether it is to describe, instruct, warn or compare. Note down keywords rather than full sentences. Underline numbers, unit changes and safety-critical information. Use a T-chart to separate what you know from new information while listening.

在听力任务中，你只会听到一至两次技术简报。训练自己识别说话者的主要目的，无论是描述、指示、警告还是比较。记下关键词而不是完整的句子。在数字、单位换算和安全关键信息下划线。使用 T 形表格将已知信息与新信息分开记录。

Listen to short engineering podcasts or video clips twice: first for gist, second for detail.
听简短的工程播客或视频片段两遍：第一遍了解大意，第二遍获取细节。
Practise predicting what might come next based on signalling words like ‘therefore’, ‘however’, ‘in addition’.
练习根据信号词（如 ‘therefore’、’however’、’in addition’）预测接下来可能的内容。

9. Managing Nerves and Improving Fluency | 克服紧张情绪与提高流利度

Nervousness can cause you to rush or forget technical terms. Control your breathing before you start speaking; pause briefly between sentences. Use hesitation devices sparingly, e.g. ‘Let me think about that…’, ‘What I mean is…’. Practise with a timer so you develop a natural rhythm. Fluency is more important than a perfect accent, so aim for a steady, confident delivery.

紧张可能导致语速过快或忘记技术术语。开始发言前调整呼吸；在句子之间稍作停顿。适度使用犹豫填充语，例如 ‘Let me think about that…’、’What I mean is…’。用计时器练习，形成自然的节奏。流利度比完美的口音更重要，力求平稳、自信的表达。

Record a 2-minute impromptu talk on an engineering topic every day and listen critically.
每天针对一个工程话题录制 2 分钟即兴发言，并进行批判性回听。
Join a study group where you take turns presenting a design solution.
加入学习小组，轮流介绍设计解决方案。

10. Using Visual Aids During Your Presentation | 在汇报中使用视觉辅助

In a speaking exam, you may be allowed to use a simple diagram, flow chart or a prototype. Point to relevant parts as you speak: ‘As you can see in this cross-section, the ribbing increases rigidity.’ Never read from notes verbatim; use bullet points or keywords as cues. Ensure any labels on your visual are large enough and correctly spelled.

在口语考试中，你可能可以使用简单的示意图、流程图或原型。发言时指着相关部分：’As you can see in this cross-section, the ribbing increases rigidity.’ 切勿逐字念稿；用要点或关键词作为提示。确保视觉辅助上的标签足够大且拼写正确。

Practise transitioning between spoken explanation and pointing to the visual smoothly.
练习在口头解释和指向视觉辅助之间流畅转换。
If using a PowerPoint slide, limit text to no more than six words per line.
如果使用幻灯片，每行文字不超过六个单词。

11. Safety Language and Risk Assessment | 安全用语与风险评估

Engineering communication invariably includes safety. Learn to express risk levels: ‘There is a high risk of entanglement if loose clothing is worn near the drill.’ Use modal verbs appropriately: ‘You must wear goggles’, ‘The guard should be in place at all times’. In listening tasks, safety instructions are often delivered with a rise in pitch or a stressed word – train your ear to pick up these cues.

工程沟通总是包含安全内容。学会表达风险等级：’There is a high risk of entanglement if loose clothing is worn near the drill.’ 恰当使用情态动词：’You must wear goggles’, ‘The guard should be in place at all times’。在听力任务中，安全指令往往通过升调或重读来强调——训练耳朵捕捉这些线索。

Memorise standard safety phrases: ’emergency stop button’, ‘isolation procedure’, ‘personal protective equipment (PPE)’.
熟记标准安全短语：’emergency stop button’（急停按钮）、’isolation procedure’（隔离程序）、’personal protective equipment (PPE)’（个人防护装备）。
Role-play a toolbox talk with a partner, covering hazards and control measures.

12. Self-Assessment and Final Preparation Tips | 自我评估与终极备考建议

In the weeks before the exam, simulate the test environment by speaking aloud to a wall or a mirror, making sure your voice fills the room. Use a checklist to tick off key elements: appropriate pace, correct technical terms, clear structure, and appropriate response to follow-up questions. For listening, revise by completing past paper audio tasks while noting down the types of distractors used.

在考试前几周，对着墙壁或镜子大声模拟发言，确保你的声音充满房间。使用清单来检查关键要素：适当的速度、正确的技术术语、条理清晰的结构以及对追问的恰当回应。对于听力，通过完成历年真题中的音频任务进行复习，并记录干扰项的类型。

Create a self-assessment grid with columns: ‘What I did well’, ‘What I can improve’, ‘New vocabulary used’.
制作一份自我评估表，包含三列：’What I did well’（我做得好的）、’What I can improve’（可改进的）、’New vocabulary used’（使用的新词汇）。
Get a good night’s sleep before the exam; a rested brain processes spoken information far more effectively.
考前好好睡一觉；充分休息的大脑处理口语信息的效率要高得多。
