Term	Pronunciation	中文
Cell	/sel/	细胞
Nucleus	/ˈnjuː.kli.əs/	细胞核
Cytoplasm	/ˈsaɪ.tə.plæz.əm/	细胞质
Mitochondria	/ˌmaɪ.təˈkɒn.dri.ə/	线粒体
Chloroplast	/ˈklɒr.ə.plæst/	叶绿体
Photosynthesis	/ˌfəʊ.təˈsɪn.θə.sɪs/	光合作用
Respiration	/ˌres.pɪˈreɪ.ʃən/	呼吸作用
Enzyme	/ˈen.zaɪm/	酶
Diffusion	/dɪˈfjuː.ʒən/	扩散

2. Describing Cells, Tissues and Organs | 描述细胞、组织和器官

Use the following sentence starters to talk about cell structures. For example: “The nucleus controls the cell’s activities. The cytoplasm is a jelly-like substance where chemical reactions occur.” Practise by describing a plant cell and an animal cell. Then listen to a short description and draw what you hear.

利用以下句型开头来谈论细胞结构。例如：“细胞核控制着细胞的活动。细胞质是一种果冻状的物质，化学反应在其中发生。”练习描述一个植物细胞和一个动物细胞。然后听一段简短的描述，并画出你所听到的内容。

Plant cell key points: “The cell wall gives the plant cell a rigid shape. Chloroplasts contain chlorophyll for photosynthesis. A large vacuole stores cell sap.” Animal cell: “Animal cells lack a cell wall and chloroplasts. They have small vacuoles if present.”

植物细胞要点：“细胞壁使植物细胞具有坚硬的形状。叶绿体含有叶绿素用于光合作用。一个大液泡储存着细胞液。”动物细胞：“动物细胞没有细胞壁和叶绿体。如果存在液泡，它们也很小。”

3. Listening to Life Processes (MRS GREN) | 听辨生命过程

MRS GREN stands for Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion and Nutrition. You will hear a sentence describing one of these processes. Identify which life process it is.

MRS GREN 代表运动、呼吸、应激性、生长、繁殖、排泄和营养。你会听到一个描述其中一个生命过程的句子，请判断它是哪一个过程。

Example sentences to read aloud for a listening partner: “The plant bends towards the light.” (Sensitivity) “The tadpole develops legs and loses its tail.” (Growth) “The rabbit gives birth to three babies.” (Reproduction) “Carbon dioxide and water vapour leave the leaf through stomata.” (Excretion)

朗读给听力伙伴的例句：“植物朝着光弯曲。”（应激性）“蝌蚪长出腿并失去尾巴。”（生长）“兔子生下三只幼崽。”（繁殖）“二氧化碳和水蒸气通过气孔离开叶片。”（排泄）

4. Oral Practice: Classifying Living Things | 口语练习：生物分类

Practise explaining why a dolphin is a mammal and not a fish. Use key features: “A dolphin breathes air through lungs and gives birth to live young, so it is a mammal. Fish have gills and lay eggs.” Record yourself and listen for fluency.

练习解释为什么海豚是哺乳动物而不是鱼。用关键特征：“海豚用肺呼吸空气并且产下活幼崽，所以它是哺乳动物。鱼有鳃并且产卵。”录下自己的声音并检查流利度。

Now discuss a penguin: “A penguin has feathers and lays eggs, so it is a bird, even though it cannot fly.” These comparisons sharpen both speaking and scientific reasoning.

现在讨论企鹅：“企鹅有羽毛并且产卵，所以它是鸟类，尽管它不会飞。”这些比较既能锻炼口语，又能提升科学推理能力。

5. Food Chains and Webs: Oral Presentation | 食物链与食物网：口头展示

Describe a simple food chain: “Grass is eaten by a rabbit, which is eaten by a fox.” Explain what would happen if one organism were removed. For instance: “If all rabbits died, foxes would have less food, so their population might decrease.” Listen to a food web description and answer questions like: “Name two producers.”

描述一个简单的食物链：“草被兔子吃，兔子被狐狸吃。”解释如果一种生物被移除会发生什么。例如：“如果所有兔子都死了，狐狸的食物就会减少，因此它们的数量可能会下降。”听一段关于食物网的描述并回答问题，如：“说出两种生产者。”

Use linking words: because, therefore, as a result. Practise with a partner: one describes a food web, the other draws it. This builds listening accuracy and oral clarity.

使用连接词：因为、因此、结果。与伙伴练习：一人描述一个食物网，另一人画出来。这能提高听力准确度和口语清晰度。

6. Pronunciation of Challenging Terms | 难发音术语的发音

Words like photosynthesis, mitochondria and chloroplast can be tricky. Break them down: pho-to-syn-the-sis, mi-to-chon-dri-a, chlo-ro-plast. Listen and repeat, then say the full word at normal speed. Pay attention to stress: pho-to-SYN-the-sis, mi-to-CHON-dri-a.

像光合作用、线粒体和叶绿体这样的词可能很难。分解它们：pho-to-syn-the-sis, mi-to-chon-dri-a, chlo-ro-plast。听然后重复，再以正常速度说出整个单词。注意重音：pho-to-SYN-the-sis, mi-to-CHON-dri-a。

Also practise: species (spee-sheez), bacteria (bak-teer-ee-uh), enzyme (en-zime), diffusion (dif-yoo-zhun). Consistent oral repetition builds muscle memory for accurate pronunciation.

也要练习：species (spee-sheez), bacteria (bak-teer-ee-uh), enzyme (en-zime), diffusion (dif-yoo-zhun). 持续的口头重复能形成肌肉记忆，确保发音准确。

7. Listening to an Experiment: Testing a Leaf for Starch | 听实验：检测叶片中的淀粉

You will hear a description of how to test a leaf for starch. Listen carefully and put the steps in order. Example script: “First, boil the leaf in water for two minutes. Then turn off the Bunsen burner and place the leaf in a tube of ethanol. Place the tube in hot water until the leaf turns white. Rinse the leaf in cold water and spread it on a white tile. Add a few drops of iodine solution.” Key words: boil, ethanol, rinse, iodine, blue-black.

你会听到一段关于如何检测叶片中淀粉的描述。仔细听并将步骤排序。示例文本：“首先，把叶片在水中煮两分钟。然后关掉本生灯，将叶片放入装有乙醇的试管中。将试管放在热水中直到叶片变白。用冷水冲洗叶片，并铺在白色瓷砖上。滴加几滴碘液。”关键词：煮沸、乙醇、冲洗、碘液、蓝黑色。

If starch is present, iodine solution will turn from yellow-brown to blue-black. This simple experiment tests the product of photosynthesis.

如果存在淀粉，碘液会从黄褐色变成蓝黑色。这个简单的实验可以检测光合作用的产物。

8. Role-Play: A Visit to the Doctor – Nutrition and Digestion | 角色扮演：看医生——营养与消化

Student A: doctor; Student B: a patient with a stomach ache. Use vocabulary: balanced diet, carbohydrates, proteins, fats, vitamins, minerals, fibre, digestion, enzymes. Practise asking and answering questions.

学生A：医生；学生B：胃痛患者。使用词汇：均衡饮食、碳水化合物、蛋白质、脂肪、维生素、矿物质、纤维素、消化、酶。练习提问和回答。

Doctor: “What have you eaten today?” Patient: “Mostly crisps and chocolate.” Doctor: “That diet lacks fibre and important nutrients. Fibre helps digestion and prevents constipation. You should include more fruits, vegetables and whole grains.”

医生：“你今天吃了什么？”病人：“主要是薯片和巧克力。”医生：“这样的饮食缺乏纤维素和重要营养素。纤维素有助于消化并防止便秘。你应该多吃水果、蔬菜和全谷物。”

9. Discussing Environmental and Human Impacts | 讨论环境与人类影响

Talk about deforestation or pollution. Use linking words: because, therefore, consequently, as a result. “Burning fossil fuels releases CO₂, which leads to global warming. Consequently, polar ice caps melt and sea levels rise.” Listen to a short speech on deforestation and summarise the main points in your own words.

讨论森林砍伐或污染。使用连接词：因为、因此、从而、结果。“燃烧化石燃料释放二氧化碳，导致全球变暖。结果，极地冰盖融化，海平面上升。”听一段关于森林砍伐的简短演讲，用自己的话总结要点。

Oral practice: “Deforestation destroys habitats, so many species lose their homes. Because trees absorb carbon dioxide, cutting them down increases the level of CO₂ in the atmosphere.”

口语练习：“森林砍伐破坏了栖息地，因此许多物种失去了家园。因为树木吸收二氧化碳，砍伐它们会提高大气中二氧化碳的含量。”

10. Mini Listening Test: KS3 Biology Topics | 迷你听力测试：KS3 生物专题

Listen to a short talk about photosynthesis. Answer the following questions: What gas is taken in? What gas is produced? Where does photosynthesis happen? What is the source of energy? Write down your answers while listening.

听一段关于光合作用的简短讲话。回答以下问题：吸收什么气体？产生什么气体？光合作用在哪里发生？能量来源是什么？边听边写下答案。

Model talk: “Photosynthesis is the process by which green plants make their own food. It occurs in the chloroplasts of leaf cells. The plant takes in carbon dioxide from the air and water from the soil. Using energy from sunlight, it converts these into glucose and oxygen. Oxygen is released into the atmosphere.” Answers: CO₂, O₂, chloroplasts, sunlight.

示范讲话：“光合作用是绿色植物制造自身食物的过程。它发生在叶细胞的叶绿体中。植物从空气中吸收二氧化碳，从土壤中吸收水分。利用来自阳光的能量，将它们转化为葡萄糖和氧气。氧气被释放到大气中。”答案：二氧化碳、氧气、叶绿体、阳光。

11. Tips for Oral Presentations and Listening Exams | 口语展示与听力考试技巧

Speak clearly and at a moderate pace. Use gestures to explain processes, such as showing the flow of energy in a food chain. Before an oral presentation, rehearse key vocabulary and organise your points into an introduction, body and conclusion.

发音清晰，语速适中。用手势解释过程，例如展示食物链中能量的流动。在口语展示前，演练关键词汇，并将要点组织成引言、主体和结论。

During listening exams, read the questions beforehand. Listen for keywords and take short notes. Do not panic if you miss something; focus on the next piece of information. Practise with past recordings or ask a friend to read biology passages aloud.

在听力考试时，提前阅读题目。抓关键词并做简短笔记。如果漏掉某个信息不要慌张，集中精力听下一条信息。用以往的录音练习，或者请朋友大声朗读生物段落。

12. Bringing It All Together | 综合运用

Combine all these skills in a final integrated activity: listen to a description of an animal cell, summarise it orally, then explain how it differs from a plant cell. This mirrors the integrated tasks you might encounter in assessments. Regular practice will make discussing biology in English feel natural and effortless.

在最后的综合活动中结合所有技能：听一段关于动物细胞的描述，口头总结，然后解释它与植物细胞的区别。这反映了你在评估中可能遇到的综合任务。经常练习将使你能够自然而轻松地用英语讨论生物。
