1. Cellular Structures – Describe and Explain | 细胞结构 – 描述与解释
Start by looking at an animal cell diagram. Speak aloud: 'The nucleus controls the cell’s activities and contains DNA. The cytoplasm is a jelly-like substance where chemical reactions take place. The cell membrane controls what enters and leaves the cell.' Then listen to a partner describe a plant cell, and draw what you hear. Pay attention to the extra structures: cell wall, large permanent vacuole, and chloroplasts.
首先看着一幅动物细胞图。大声描述出来：“细胞核控制细胞的活动并含有 DNA。细胞质是一种胶状物质，化学反应在这里进行。细胞膜控制物质进出细胞。”然后听一位搭档描述植物细胞，并根据你听到的内容画出来。注意植物细胞特有的结构：细胞壁、中央大液泡和叶绿体。
- Key vocabulary to pronounce: nucleus /ˈnjuːkliəs/, cytoplasm /ˈsaɪtəplæzəm/, membrane /ˈmembreɪn/, chloroplast /ˈklɒrəplɑːst/.
- 重点词汇发音： nucleus（细胞核）、cytoplasm（细胞质）、membrane（膜）、chloroplast（叶绿体）。
2. Diffusion and Osmosis – Listen and Retell | 扩散与渗透 – 听力复述
Listen to this short description: 'Diffusion is the net movement of particles from a region of higher concentration to a region of lower concentration, down a concentration gradient. It is a passive process that does not require energy. Oxygen diffuses into red blood cells in the lungs.' Now close your eyes and retell the definition using your own words. For osmosis, listen: 'Osmosis is the movement of water molecules from a dilute solution to a more concentrated solution across a partially permeable membrane.' Retell it and give an example using a potato strip in pure water.
听这段简短描述：“扩散是粒子净从高浓度区域往低浓度区域顺浓度梯度移动的过程。这是一个被动过程，不需要能量。氧气在肺部扩散进入红细胞。”现在闭上眼睛，用自己的话复述这个定义。关于渗透，请听：“渗透是水分子通过选择性半透膜从稀溶液向较浓溶液移动的过程。”复述并举例说明，比如把土豆条放入纯水的情况。
Diffusion: High concentration → Low concentration (passive)
渗透：水分子从高水势移动到低水势
3. Enzyme Action – Role-play Dialogue | 酶的作用 – 角色扮演对话
Work with a partner. One person plays 'Substrate', the other 'Enzyme'. Create a dialogue explaining the lock-and-key model. For example, Enzyme says: 'I have an active site that is complementary to your shape. You are the substrate.' Substrate replies: 'I fit into your active site, forming an enzyme-substrate complex. Then you lower the activation energy, and I am broken down into products.' Swap roles and include the terms 'denatured' and 'optimal temperature'.
和搭档一起练习。一人扮演“底物”，另一人扮演“酶”。编写一段解释锁钥模型的对话。例如，酶说：“我有一个活性位点，与你的形状互补。你就是底物。”底物回答：“我进入你的活性位点，形成酶-底物复合物。然后你降低活化能，我就被分解为产物。”交换角色，并将“变性”和“最适温度”这些术语融入对话中。
The key expression to practise: 'The active site is complementary to the substrate.'
需要练习的关键表达：“活性位点与底物互补。”
4. Digestive System Journey – Oral Storytelling | 消化系统之旅 – 口述故事
Imagine you are a piece of bread. Narrate your journey through the digestive system aloud. Begin: 'I enter the mouth, where teeth and saliva begin mechanical and chemical digestion. Amylase in saliva breaks starch into maltose. I travel down the oesophagus by peristalsis into the stomach.' Continue through the stomach (pepsin digests protein), small intestine (lipase, protease, and pancreatic amylase digest fats, proteins, and starch), and large intestine (water absorption). Finish with egestion.
想象你是一片面包。口头叙述你经过消化系统的旅程。开始：“我进入口腔，牙齿和唾液开始进行机械消化和化学消化。唾液中的淀粉酶把淀粉分解为麦芽糖。我经过蠕动沿食道向下进入胃。”继续经过胃（胃蛋白酶消化蛋白质）、小肠（脂肪酶、蛋白酶和胰淀粉酶消化脂肪、蛋白质和淀粉）和大肠（吸收水分）。最后以排遗结束。
Use connecting words: first, then, next, after that, finally. Record yourself and listen for fluency.
使用连接词：首先、然后、接下来、之后、最后。录下你的叙述，听听是否流畅。
5. Breathing and Gas Exchange – Partner Discussion | 呼吸与气体交换 – 搭档讨论
Discuss with a partner how inhalation works. One student asks: 'What happens to the intercostal muscles and the diaphragm during inhalation?' The other responds: 'The intercostal muscles contract and move the ribcage up and out. The diaphragm contracts and flattens. This increases the volume of the thorax, decreasing the pressure, so air rushes in.' Listen carefully and correct any mistakes. Then switch to describe exhalation.
与搭档讨论吸气过程。一位学生问：“吸气时肋间肌和膈肌发生了什么？”另一位回答：“肋间肌收缩，使胸腔向上向外移动。膈肌收缩并变平。这增加了胸腔容积，降低压力，于是空气涌入。”仔细聆听，改正任何错误。然后交换，描述呼气过程。
Key listening task: Draw a spirometer trace while your partner explains tidal volume and vital capacity.
关键听力任务：边听搭档解释潮气量和肺活量，边画出肺量计曲线图。
6. Photosynthesis Equation – Chant and Memorise | 光合作用方程式 – 吟诵记忆
Read the word equation aloud rhythmically: Carbon dioxide + Water → Glucose + Oxygen, in the presence of light and chlorophyll. Then chant the balanced symbol equation:
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
Listen to a recording of the equation and repeat it until you can say it without hesitation. Create a song or rhyme to make it stick. Then explain aloud what the equation tells us: that six molecules of carbon dioxide and six of water produce one glucose and six oxygen molecules, using light energy absorbed by chlorophyll.
有节奏地大声朗读文字方程式：二氧化碳 + 水 → 葡萄糖 + 氧气，需要光和叶绿素。然后吟诵配平的化学方程式：
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
听方程式的录音，并跟着重复，直到你能毫不犹豫地说出口。编一首歌或韵律帮助记忆。然后口头解释这个方程式的含义：六个二氧化碳分子和六个水分子生成一个葡萄糖分子和六个氧分子，利用叶绿素吸收的光能。
7. Food Chains and Webs – Listening Quiz | 食物链和食物网 – 听力测验
Ask a friend to read out a food web description: 'The oak tree is a producer. Aphids feed on the oak, so they are primary consumers. Ladybirds eat aphids – they are secondary consumers. Blue tits eat ladybirds, and sparrowhawks eat blue tits.' Listen without writing, then draw the food chain or web from memory. Check your accuracy. Then swap roles and describe a marine food chain starting with phytoplankton, using terms like producer, herbivore, carnivore, and omnivore.
请一位朋友朗读食物网的描述：“橡树是生产者。蚜虫以橡树为食，所以它们是初级消费者。瓢虫吃蚜虫——它们是次级消费者。蓝山雀吃瓢虫，雀鹰吃蓝山雀。”只听不写，然后凭记忆画出食物链或食物网。检查准确性。然后交换角色，描述一条以浮游植物为起点的海洋食物链，使用生产者、食草动物、食肉动物和杂食动物等术语。
Practise the word 'herbivore' /ˈhɜːbɪvɔː/ clearly, as it is often mispronounced.
练习清晰发音 'herbivore' /ˈhɜːbɪvɔː/，这个词经常被念错。
8. Inheritance and Variation – Debate Points | 遗传与变异 – 辩论要点
Prepare a 2-minute spoken argument on 'Are identical twins completely the same?' Use biological evidence. Say: 'Identical twins result from one fertilised egg splitting into two. Therefore, they have the same genotype. However, environmental factors such as diet, lifestyle, and exposure to different conditions can cause variation in phenotype. Epigenetic changes can also make them differ over time.' Listen to a partner's counter-argument and respond.
准备一段两分钟的口头辩论，主题是“同卵双胞胎完全一样吗？”使用生物学证据。可以说：“同卵双胞胎来自一个受精卵分裂成两个。因此，他们的基因型相同。然而，环境因素如饮食、生活习惯和接触不同条件都会导致表型差异。表观遗传变化也会让他们随时间推移变得不同。”聆听搭档的反驳并做出回应。
Vocabulary to articulate: genotype, phenotype, environment, variation, inherited, acquired.
需要清晰表达的词汇：基因型、表型、环境、变异、遗传的、获得的。
9. Respiration – Compare and Contrast Speaking Task | 呼吸作用 – 比较对比口语任务
Explain the difference between aerobic and anaerobic respiration without looking at your notes. State: 'Aerobic respiration uses oxygen to release energy from glucose. The word equation is: Glucose + Oxygen → Carbon dioxide + Water (+ energy). Anaerobic respiration in animal cells produces lactic acid and less energy, while in yeast it produces ethanol and carbon dioxide.' Then compare the two using a Venn diagram you describe aloud.
不看笔记，解释有氧呼吸和无氧呼吸的区别。可以说：“有氧呼吸利用氧气从葡萄糖中释放能量。文字方程式为：葡萄糖 + 氧气 → 二氧化碳 + 水（+ 能量）。动物细胞的无氧呼吸产生乳酸和较少能量，而酵母则产生乙醇和二氧化碳。”然后一边口述，一边用维恩图比较两者。
Anaerobic (animals): Glucose → Lactic acid + Energy
Anaerobic (yeast): Glucose → Ethanol + CO₂ + Energy
For your listening practice, a partner can read a description of a marathon runner's respiration and you must identify when each type occurs.
在听力练习中，搭档可以描述马拉松运动员的呼吸情况，你必须辨别出各种呼吸类型发生的时间点。
10. Exam-Tip Vocabulary Pronunciation | 考试技巧：词汇发音
Many students lose marks in oral tasks simply because they mispronounce key terms. Use the table below to practise tricky words. Read them aloud, record yourself, and compare with standard pronunciation. Create flashcards with the term on one side and the phonetic spelling on the other.
很多学生在口语任务中丢分，仅仅是因为关键术语发音错误。利用下表练习容易读错的单词。大声朗读、录音，并与标准发音进行对比。制作抽认卡，一面写术语，另一面写音标。
| Term (English) | Pronunciation | 中文术语 |
|---|---|---|
| mitochondria | /ˌmaɪtəˈkɒndriə/ | 线粒体 |
| haemoglobin | /ˌhiːməˈɡləʊbɪn/ | 血红蛋白 |
| deoxyribonucleic acid | /diˌɒksɪˌraɪbəʊnjuːˈkliːɪk/ | 脱氧核糖核酸 |
| palisade mesophyll | /ˌpælɪˈseɪd ˈmesəfɪl/ | 栅栏叶肉 |
| lymphocyte | /ˈlɪmfəsaɪt/ | 淋巴细胞 |
Regularly test your listening by having someone read a definition; you identify the term and spell it aloud. This builds both your vocabulary and aural exam skills.
经常做听力测验：让别人读一个定义，你辨别出术语并口头拼写。这样能同时扩展词汇量和听力考试技巧。
