Preparing for the speaking and listening aspects of your Cambridge Year 7 Biology course means more than just memorising facts – it is about building confidence in using scientific language aloud and understanding spoken explanations in the classroom and in assessments. This guide takes you through essential vocabulary, common question types, practical role‑plays and listening strategies, helping you to talk like a young scientist and follow instructions with ease.
准备剑桥7年级生物的口语与听力考试不仅仅是记住知识点——更关键的是要敢于大声使用科学语言，并能在课堂和评估中听懂老师的讲解。本指南将带你学习核心词汇、常见题型、实用的角色扮演以及听力策略，帮助你像一个小科学家一样自信表达，轻松理解所听到的内容。
1. Mastering Biological Vocabulary Pronunciation | 掌握生物词汇发音
Many biology terms come from Latin or Greek, so learning to break words into syllables is the first step towards correct pronunciation. For example, ‘mitochondria’ can be sounded out as my‑toh‑KON‑dree‑uh, while ‘nucleus’ becomes NEW‑klee‑us.
许多生物学术语源自拉丁语或希腊语，因此把单词拆分成音节是正确发音的第一步。比如，“mitochondria”（线粒体）可以读作 my‑toh‑KON‑dree‑uh，“nucleus”（细胞核）则读作 NEW‑klee‑us。
Practise saying ‘cytoplasm’ (SY‑toh‑plaz‑uhm) and ‘cell membrane’ with a clear voice. Remember that the stress often falls on the second or third syllable. Record yourself and compare with your teacher’s pronunciation.
练习清晰地说出“cytoplasm”（细胞质，读作 SY‑toh‑plaz‑uhm）和“cell membrane”（细胞膜）。要记住重音通常落在第二或第三个音节上。把自己的发音录下来，与老师的发音进行对比。
| Term | Pronunciation Guide | 中文 |
|---|---|---|
| chloroplast | KLOR‑oh‑plast | 叶绿体 |
| vacuole | VAK‑yoo‑ohl | 液泡 |
| respiration | res‑puh‑RAY‑shuhn | 呼吸作用 |
| photosynthesis | foh‑toh‑SIN‑thuh‑sis | 光合作用 |
2. Describing Animal and Plant Cells | 描述动物和植物细胞
When you are asked to describe a cell, use simple comparative sentences. Say, ‘A plant cell has a cell wall, chloroplasts and a large vacuole, but an animal cell does not.’ Learn to point out the function of each part: ‘The nucleus controls the cell’s activities.’
当你被要求描述一个细胞时，请用简单的比较句。可以说：“植物细胞有细胞壁、叶绿体和大型液泡，但动物细胞没有。” 学会指出各部分的功能：“细胞核控制细胞的活动。”
Practise the phrase ‘The cytoplasm is a jelly‑like substance where chemical reactions happen.’ Repeat it several times until it sounds natural. This will help you during short speaking tasks where you need to label or explain a diagram.
练习这个句子：“细胞质是一种果冻状的物质，是发生化学反应的场所。” 多重复几遍，直到说得自然。这会在你需要标注或解释图表的口语短任务中帮到你。
Listen for keywords like ‘organelle’, ‘cell sap’ and ‘chlorophyll’ in audio clips. Your teacher may describe a cell and ask you to identify it. Train your ear to catch differences between ‘rigid cell wall’ and ‘flexible cell membrane’.
在听力片段中留意关键词，如“organelle（细胞器）”“cell sap（细胞液）”和“chlorophyll（叶绿素）”。老师可能会描述一个细胞并让你辨认，训练耳朵捕捉“坚硬的细胞壁”和“有弹性的细胞膜”之间的区别。
3. Talking About Classification Keys | 讨论分类检索表
Classification keys are used to identify living things by asking a series of yes/no questions. In a speaking exam you might be asked to explain how a key works. Say, ‘Does the organism have a backbone? If yes, go to step 2; if no, it is an invertebrate.’
分类检索表通过一系列“是/否”问题来鉴定生物。在口语考试中，你可能要解释检索表的用法。可以说：“这种生物有脊椎吗？如果有，看第二步；如果没有，它就是无脊椎动物。”
Role‑play with a partner: one person picks an animal (e.g. frog, spider), and the other asks questions such as ‘Does it have legs?’ or ‘Is its body covered with fur?’ This builds both your questioning skills and listening accuracy.
和搭档进行角色扮演：一个人选一种动物（如青蛙、蜘蛛），另一个人提问，如“它有腿吗？”或“它的身体是否覆盖着毛？”这既能锻炼提问技巧，又能提高听力准确性。
Listen carefully for descriptive words like ‘segmented’, ‘exoskeleton’ and ‘warm‑blooded’. A typical listening task might present clues about an unknown creature; you need to jot down keywords and select the correct group.
仔细听描述性词语，如“分节（segmented）”“外骨骼（exoskeleton）”和“温血（warm‑blooded）”。典型的听力任务可能会给出一种未知生物的线索，你需要记录关键词并选出正确的类别。
4. Explaining the Seven Life Processes | 解释七个生命过程
Remember the acronym MRS GREN: Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion, Nutrition. Practice defining each process in a full sentence. For example, ‘Excretion is the removal of waste products from the body.’
记住首字母缩略词 MRS GREN：运动、呼吸、感应、生长、生殖、排泄、营养。练习用完整的句子定义每一个过程。例如：“排泄是把废物从身体里排出去。”
During speaking tasks you might be asked to explain whether a car or a fire is alive. Be ready to say, ‘A fire does not have cells, so it cannot carry out all seven life processes; therefore it is not living.’
在口语任务中，你可能会被问到汽车或火是否是有生命的。做好准备说：“火没有细胞，所以它无法完成全部七个生命过程，因此不是生物。”
Listening exercises often feature a description of an organism’s activity. Listen for verbs like ‘breathes’, ‘feeds’, ‘grows’ and ‘responds’. If you hear all seven processes mentioned, you can confidently conclude it is a living thing.
听力练习常常描述某种生物的活动。留意“呼吸”“摄食”“生长”“对刺激作出反应”等动词。如果你听到所有七个过程都被提及，就可以自信地得出结论：它是生物。
5. Discussing Food Chains and Interdependence | 讨论食物链和相互依赖
Start with the sun as the ultimate source of energy. Say, ‘The producer, usually a green plant, traps light energy through photosynthesis.’ Then continue, ‘The primary consumer eats the producer, and the secondary consumer eats the primary consumer.’
从太阳这一最终能量来源说起。可以说：“生产者，通常是绿色植物，通过光合作用捕获光能。”接着往下说：“初级消费者吃生产者，次级消费者吃初级消费者。”
Use arrows to show energy flow, and practise describing them verbally: ‘The arrow points from the eaten organism to the eater, showing the direction of energy transfer.’ This is a common exam instruction.
用箭头表示能量流动，并练习口头描述箭头：“箭头从被捕食的生物指向捕食者，表示能量传递的方向。”这是考试中常见的指令。
In a listening task, you may hear a food chain described out of order. Your job is to rearrange it and write the correct sequence. Listen for phrases such as ‘is eaten by’ or ‘feeds on’.
在听力任务中，你可能会听到顺序被打乱的食物链。你需要重新排列并写下正确的顺序。留意“被……吃掉”或“以……为食”这类短语。
6. Listening for Instructions in the Lab | 听取实验室指令
Safety is the most important part of any practical lesson. Before you begin, you must understand spoken instructions like ‘Put on safety goggles’, ‘Tie back long hair’ and ‘Do not taste any chemicals’.
在所有实验课中安全都是最重要的。在开始前，你必须听懂口头指令，例如“戴上护目镜”“把长发扎起来”以及“不要尝任何化学品”。
When listening to a procedure, tune in to sequence words: ‘First, light the Bunsen burner on a yellow flame. Then, set up the microscope.’ Repeat these steps back to your partner to practise speaking clearly.
听实验步骤时，请留意顺序词：“首先，点燃本生灯，调到黄色火焰。然后，安装好显微镜。”把这些步骤复述给搭档听，练习清晰的口语表达。
Common lab verbs include ‘measure’, ‘pour’, ‘heat’, ‘observe’ and ‘record’. Create flashcards with pictures and say the action out loud. This will help you follow spoken directions during a listening test.
常见的实验动词包括“测量”“倒”“加热”“观察”和“记录”。制作带图片的单词卡，并大声说出动作。这能帮助你在听力测试中跟上口头指导。
7. Describing the Skeleton and Muscles | 描述骨骼与肌肉
When talking about the human skeleton, use the phrase ‘The skeleton provides support, protects organs and allows movement.’ Practise naming bones clearly: ‘skull’, ‘ribcage’, ‘spine’, ‘femur’.
谈论人体骨骼时，使用这个句子：“骨骼提供支撑、保护内脏并让身体能够运动。”练习清晰地命名骨骼：“颅骨”“胸廓”“脊柱”“股骨”。
Explain how muscles work in pairs: ‘When the biceps contracts, the triceps relaxes, and the arm bends.’ Practise this explanation while pointing to your own arm; your spoken description will become more natural.
解释肌肉是如何成对工作的：“当肱二头肌收缩时，肱三头肌就放松，手臂就弯曲了。”一边指着自己的手臂一边练习这个解释，你的口头描述会变得更自然。
In a listening clip you might hear something like ‘The fixed end of a muscle is attached to an immovable bone.’ Train your ear to catch terms such as ‘tendon’, ‘antagonistic pair’ and ‘joint’.
在听力片段中，你可能会听到类似“肌肉的固定端连在不动的骨头上”的说法。训练耳朵捕捉“肌腱”“拮抗肌对”和“关节”等术语。
8. Explaining Photosynthesis and Respiration | 解释光合作用与呼吸作用
Photosynthesis can be summarised with the word equation: carbon dioxide + water → glucose + oxygen, in the presence of light and chlorophyll. Say it slowly: ‘Carbon dioxide and water react to produce glucose and oxygen, using light energy trapped by chlorophyll.’
光合作用可以用文字方程式概括：二氧化碳 + 水 → 葡萄糖 + 氧气，需要光和叶绿素。慢慢说：“二氧化碳和水在叶绿素捕获的光能作用下，生成葡萄糖和氧气。”
Respiration is the process that releases energy from glucose. Its word equation is glucose + oxygen → carbon dioxide + water (+ energy). Practise contrasting the two processes: ‘Photosynthesis makes food; respiration breaks it down to release energy.’
呼吸作用是葡萄糖释放能量的过程。文字方程式为：葡萄糖 + 氧气 → 二氧化碳 + 水（+ 能量）。练习对比这两个过程：“光合作用制造食物；呼吸作用分解食物以释放能量。”
Listening tasks often ask you to distinguish between the two. You might hear a description of gas exchange in leaves. Focus on whether carbon dioxide is being taken in or given out.
听力任务常常要求你区分这两个过程。你可能会听到对叶片气体交换的描述，要集中注意力分辨二氧化碳是被吸收还是被释放。
9. Practising with Microscope Terminology | 显微镜术语练习
Handling a microscope requires precise language. Repeat these steps: ‘Place the slide on the stage and secure it with the clips. Select the lowest power objective lens and turn the coarse focus knob until the image becomes clear.’
操作显微镜需要用词准确。请复述这些步骤：“将载玻片放在载物台上，用夹子固定。选择最低倍率的物镜，转动粗准焦螺旋直到图像清晰为止。”
Learn the names of the parts: eyepiece, objective lens, stage, mirror (or light source), coarse and fine focus knobs. Describe their functions: ‘The eyepiece magnifies the image so you can see the specimen.’
记住各部件的名称：目镜、物镜、载物台、反光镜（或光源）、粗准焦螺旋和细准焦螺旋。描述它们的功能：“目镜放大图像，让你能观察到标本。”
In a spoken exam, you might be given a diagram of a microscope and asked to explain how to view a specimen. Use sequencing words: ‘First… next… then… finally’. This structure keeps your answer clear.
在口语考试中，你可能会拿到显微镜的图表并被要求解释如何观察标本。使用顺序词：“首先……接着……然后……最后”。这种结构能让你的回答清晰明了。
10. Role‑Playing an Ecologist: Habitats and Adaptations | 角色扮演生态学家：栖息地与适应
Imagine you are an ecologist visiting a pond. Describe what you see: ‘The frog has webbed feet, which are an adaptation for swimming.’ Then link the adaptation to the habitat: ‘The pond provides water and shelter, so the frog is well suited to live there.’
想象你是一位生态学家，正在考察一个池塘。描述你看到的：“青蛙有蹼足，这是对游泳的一种适应。”然后将适应性与栖息地联系起来：“池塘提供了水和庇护所，因此青蛙非常适合在那里生活。”
Practise asking and answering questions with a partner: ‘How is a camel adapted to the desert?’ Answer using key phrases like ‘hump stores fat’, ‘long eyelashes keep out sand’ and ‘wide feet stop sinking’.
与搭档练习一问一答：“骆驼是如何适应沙漠的？”用关键短语回答，比如“驼峰储存脂肪”“长长的睫毛阻挡沙子”和“宽大的脚掌防止下陷”。
Listening exercises often present two or more animals and ask you to match each to its habitat. Take notes on words like ‘nocturnal’, ‘thick fur’ and ‘needle‑like leaves’.
听力练习通常会描述两三种动物，让你将每种动物与其栖息地配对。记录如“夜行性”“厚度毛皮”和“针形叶”等词汇。
11. Common Listening Tasks: Multiple Choice and Note‑Taking | 常见听力任务：选择题与记笔记
Before an audio clip starts, read the questions carefully. Underline keywords in your mind: if the question asks ‘What does the plant need for photosynthesis?’, listen for ‘light’, ‘carbon dioxide’ and ‘water’.
在音频开始前，仔细阅读题目。在脑海里划出关键词：如果问题是“植物进行光合作用需要什么？”，就要留神听“光”“二氧化碳”和“水”。
For multiple‑choice questions, eliminate wrong answers as you listen. If the speaker says ‘The tadpole uses gills, not lungs’, you can immediately cross out any option mentioning lungs for that stage.
对于选择题，要边听边排除错误选项。如果说话者说“蝌蚪用鳃呼吸，而不是肺”，你就可以立刻划掉该阶段所有提到肺的选项。
Practice note‑taking by writing single words or short phrases. Use symbols: an arrow (→) for ‘leads to’ or ‘produces’, and a plus sign (+) for ‘and’. This technique saves time and keeps you focused on the audio.
练习记笔记时只写单个词或简短短语。使用符号：用箭头（→）表示“导致”或“产生”，用加号（+）表示“和”。这个方法能节约时间，并让你保持专注。
12. Tips for Exam Speaking Tasks | 口语考试技巧
When you are given a prompt card, take a deep breath and read it slowly. Plan your answer by thinking of three key points. For instance, if the topic is ‘Respiration’, you could mention where it happens, what it releases and why organisms need it.
当你拿到提示卡时，深呼吸并慢慢地阅读。想好三个要点来组织你的回答。例如，如果主题是“呼吸作用”，你可以提到它在哪里发生、释放了什么以及生物为什么需要它。
Speak at a steady pace – not too fast. Use linking words like ‘first of all’, ‘in addition’ and ‘finally’. Even if you make a small mistake, keep going. The examiner wants to hear your scientific understanding, not perfect English.
用平稳的语速说话——不要太快。使用连接词，如“首先”“此外”“最后”。即使犯了一点小错，也要继续说下去。考官想听到的是你的科学理解，而不是完美的英语。
Practise with recordings: record your own explanation of photosynthesis, then listen back. Check whether you used the correct key terms and whether your sentences were complete. Regular practice builds both fluency and confidence.
用录音练习：把自己的光合作用解释录下来，然后回听。检查是否使用了正确的关键术语，句子是否完整。经常练习能同时提高流利度和自信心。
