📚 Cross-curricular Integrated Question Training in Year 7 Cambridge Physical Education | Year 7 Cambridge 体育跨学科综合题型训练
Year 7 Cambridge Physical Education is far more than just playing games. It is a subject where mathematics, science, geography and languages all come together. This article introduces cross-curricular integrated question training – a way to practise your skills by solving problems that blend PE with other subjects. You will learn through real-life sporting examples, data analysis, scientific explanations and thoughtful reflections.
Year 7 剑桥体育课程远不止是玩耍和运动。这是一门融合了数学、科学、地理和语言的多学科课程。本文介绍跨学科综合题型训练——通过解决体育与其他学科相结合的问题来锻炼你的能力。你将通过真实的运动实例、数据分析、科学解释和深入反思来学习。
1. Why Cross-curricular Learning Matters in PE | 为什么体育需要跨学科学习
Sport does not exist in isolation. When you monitor your heart rate, you use mathematics. When you explain how muscles contract, you call on biology. A good PE lesson therefore encourages you to connect knowledge from different subjects. This integrated approach helps you understand your body, improve performance and become a more confident problem-solver.
运动并不是孤立存在的。当你监测心率时，你用到数学。当你解释肌肉如何收缩时，你运用生物学。因此，一堂好的体育课会鼓励你将不同学科的知识联系起来。这种综合方法有助于你了解自己的身体、提高运动表现，并成为更自信的问题解决者。
Integrated question training means you will answer questions that require knowledge from two or more subjects. For example, you might be asked to calculate how far you run during a warm-up (maths) and then describe how the surface affects friction (physics). These questions mirror the real challenges a coach or an athlete faces.
综合题型训练意味着你将回答需要两个或以上学科知识的问题。例如，你可能会被要求计算热身时跑的距离（数学），然后描述地面如何影响摩擦力（物理）。这些问题反映了教练或运动员面临的真实挑战。
2. Mathematics in PE: Heart Rate Calculations | 数学在体育中：心率计算
Understanding your heart rate zones is essential for training safely and effectively. The most basic formula to estimate maximum heart rate (MHR) is:
了解心率区间对于安全有效的训练至关重要。估算最大心率 (MHR) 最基本的公式是：
MHR = 220 – age (in years)
If you are 11 years old, your estimated MHR is 220 – 11 = 209 beats per minute (bpm). To work in the aerobic training zone, you should aim for 60% to 80% of your MHR.
如果你 11 岁，你的估算 MHR 是 220 – 11 = 209 次/分钟 (bpm)。要在有氧训练区内运动，你应该达到 MHR 的 60% 到 80%。
Lower limit = 0.60 × 209 = 125.4 bpm. Upper limit = 0.80 × 209 = 167.2 bpm. So your target heart rate zone is approximately 125 to 167 bpm. Integrated question: ‘During a 10-minute run, your heart rate is 155 bpm. Are you in the aerobic zone? Show your working and explain why this zone is beneficial for endurance.’
下限 = 0.60 × 209 = 125.4 bpm。上限 = 0.80 × 209 = 167.2 bpm。因此你的目标心率区间大约是 125 到 167 bpm。综合题：“在 10 分钟跑步中，你的心率是 155 bpm。你是否在有氧区间内？请写出计算过程，并解释为什么该区间对耐力有益。”
3. Science in PE: Energy Systems and Recovery | 科学在体育中：能量系统与恢复
Your body uses different energy systems depending on the intensity and duration of exercise. The sprint at the start of a race relies on the anaerobic system, which does not need oxygen but causes your muscles to produce lactic acid quickly. A long-distance jog uses the aerobic system, which requires oxygen and burns carbohydrates and fats.
你的身体根据运动强度和持续时间使用不同的能量系统。比赛开始时的冲刺依靠无氧系统，该系统不需要氧气，但会使肌肉迅速产生乳酸。长距离慢跑使用有氧系统，该系统需要氧气并燃烧碳水化合物和脂肪。
Integrated question: ‘A Year 7 pupil runs 800 m. For the first 100 m she sprints, then settles into a steady pace. Identify which energy system is dominant in each phase. Explain why her breathing rate increases and what happens to carbon dioxide levels in her blood.’ This demands a blend of biology and physics.
综合题：“一名 Year 7 学生跑 800 米。前 100 米她冲刺，然后保持稳定配速。请指出每个阶段中占主导地位的能量系统。解释为何她的呼吸频率会上升，以及血液中二氧化碳水平会发生什么变化。”这需要结合生物学和物理学知识。
4. Physics in PE: Levers, Motion, and Friction | 物理在体育中：杠杆、运动与摩擦
Our limbs act as levers. When you kick a football, the knee acts as the fulcrum, the quadriceps provides the effort, and the foot applies the load. A longer leg creates a longer effort arm, which can give the ball more speed if the same force is applied. This is the same principle that makes a long spanner more effective at turning a bolt.
我们的四肢就像杠杆。当你踢足球时，膝盖充当支点，股四头肌提供动力，脚施加负荷。较长的腿形成更长的力臂，如果施加相同的力，就能给球带来更快的速度。这与长扳手更容易拧动螺栓的原理相同。
Friction is another key concept. On a dry grass hockey pitch, friction between the ball and the surface slows the ball down. On a wet artificial surface, friction is lower and the ball rolls faster. Integrated question: ‘A hockey player pushes the ball with the same force on two different surfaces. Explain how friction affects the distance the ball travels. Use scientific keywords such as opposing force and motion.’
摩擦力是另一个关键概念。在干燥的草地曲棍球场上，球与地面之间的摩擦力会使球减速。在湿滑的人造草皮上，摩擦力较小，球滚得更快。综合题：“一名曲棍球运动员在两种不同地面上用同样的力推球。请解释摩擦力如何影响球的移动距离。使用如反作用力和运动等科学关键词。”
5. Biology in PE: The Musculoskeletal System | 生物在体育中：肌肉骨骼系统
To move effectively, you need to know how muscles and bones work together. When you perform a bicep curl, the biceps contract (shorten) while the triceps relax. This is called an antagonistic pair. The shoulder is a ball-and-socket joint allowing a wide range of motion, whereas the knee is a hinge joint that only allows flexion and extension.
要想高效运动，你需要了解肌肉和骨骼如何协同工作。当你做弯举动作时，二头肌收缩（变短），而三头肌放松。这称为拮抗肌对。肩关节是球窝关节，活动范围很大，而膝关节是铰链关节，只允许屈曲和伸展。
Integrated question: ‘During a press-up, identify the type of joint at the elbow. Name the prime mover (agonist) muscle when you push your body up. Explain what happens to this muscle at a cellular level, referring to oxygen and glucose.’ This links anatomy with energy science.
综合题：“做俯卧撑时，指出肘关节的类型。说出当你向上推起身体时的原动肌（主动肌）。从细胞层面解释该肌肉发生了什么，需提及氧气和葡萄糖。”这连接了解剖学和能量科学。
6. Nutrition Science: Balanced Diet for Athletes | 营养科学：运动员的均衡饮食
Food provides the fuel for all physical activity. Carbohydrates are the body’s main source of energy during moderate to high-intensity exercise. Proteins help repair and build muscle tissue. Fats supply energy for long, low-intensity activities. Vitamins and minerals, such as iron and calcium, support oxygen transport and bone strength.
食物为所有身体活动提供燃料。碳水化合物是中高强度运动期间身体的主要能量来源。蛋白质有助于修复和构建肌肉组织。脂肪为长时间低强度活动提供能量。维生素和矿物质，如铁和钙，支持氧气运输和骨骼强度。
Integrated question: ‘A school lunch contains 60 g of carbohydrate, 20 g of protein, and 15 g of fat. Given that 1 g of carbohydrate provides 4 kcal, 1 g of protein provides 4 kcal, and 1 g of fat provides 9 kcal, calculate the total energy content of the meal. Then suggest one post-exercise snack for a Year 7 pupil and justify your choice using biological reasoning.’
综合题：“一份学校午餐含有 60 克碳水化合物、20 克蛋白质和 15 克脂肪。已知 1 克碳水化合物提供 4 千卡，1 克蛋白质提供 4 千卡，1 克脂肪提供 9 千卡，计算该餐的总能量。然后为一名 Year 7 学生推荐一份运动后零食，并用生物学论证你的选择。”
7. Geography in PE: Environmental Factors in Sport | 地理在体育中：运动中的环境因素
Where you play sport matters. At high altitude, the air is thinner and contains less oxygen, which makes breathing harder. In hot climates, athletes sweat more, losing water and electrolytes, which can lead to dehydration and heatstroke. Wind resistance can slow a sprinter down, while a tailwind can help a javelin fly further.
你在哪里运动很重要。在高海拔地区，空气较稀薄，含氧量较低，这会使呼吸更加困难。在炎热气候下，运动员出汗更多，流失水分和电解质，可能导致脱水和中暑。逆风会减慢短跑运动员的速度，而顺风则能帮助标枪飞得更远。
Integrated question: ‘A football team from the UK travels to play a match in Mexico City (altitude 2,250 m). Explain why the players might feel tired more quickly. Research the term acclimatisation and describe two ways the body adapts over a week.’ This blends geography with human biology.
综合题：“一支来自英国的足球队前往墨西哥城（海拔 2,250 米）比赛。解释为什么球员可能会更快感到疲劳。研究“适应”一词，并描述身体在一周内适应环境的两种方式。”这融合了地理学和人体生物学。
8. English in PE: Analysing Instructions and Reflecting | 英语在体育中：分析指令与反思
Clear communication is vital in sport. Coaches give instructions using imperatives and technical vocabulary. As a student, you need to interpret these accurately and sometimes write your own sequences. Reflection after a performance helps you identify strengths and areas to improve.
清晰的沟通在运动中至关重要。教练使用祈使句和技术词汇发出指令。作为学生，你需要准确理解这些指令，有时自己也要写出动作序列。运动后的反思能帮助你识别优势与需要改进的方面。
Integrated question: ‘Read the following coaching instruction: “Pivot on your non-dominant foot, bring your arm back, and release the ball at eye level.” Identify the three imperatives. Then rewrite the instruction for a left-handed netball player. After trying the skill, write a short reflective paragraph evaluating what worked and what you would change.’ This develops literacy within a PE setting.
综合题：“阅读以下教练指令：‘以非惯用脚为轴转身，手臂后引，在眼睛高度将球传出。’找出三个祈使动词。然后为一名左手持球的篮网球运动员改写指令。尝试该技能后，写一段简短的反思，评价哪些部分做得好，你会如何改进。”这在体育环境中培养读写能力。
9. Data Handling: Interpreting Fitness Data | 数据处理：解读健康数据
Fitness tests generate numbers that need to be understood. You might measure your resting heart rate every morning for a week, perform a 12-minute Cooper run, or count how many sit-ups you can do in 60 seconds. Presenting this data in a bar chart or line graph helps to spot trends and set targets.
体能测试产生的数据需要被理解。你可能在一周内每天早晨测量静息心率，进行一次 12 分钟库珀跑，或者数数你在 60 秒内能做多少个仰卧起坐。用条形图或折线图展示这些数据有助于发现趋势并设定目标。
Here is a simple dataset from a Year 7 pupil’s vertical jump test over four weeks: Week 1: 28 cm; Week 2: 30 cm; Week 3: 29 cm; Week 4: 33 cm. Integrated question: ‘Calculate the mean and range of the jump heights. Describe the overall trend. Suggest one mathematical reason why a graph is better than a table for showing progress.’ You combine maths, PE and evaluation.
以下是某 Year 7 学生四周的垂直跳测试数据：第一周 28 厘米，第二周 30 厘米，第三周 29 厘米，第四周 33 厘米。综合题：“计算这些跳跃高度的平均值和极差。描述总体趋势。提出一个数学理由，说明为什么图表比表格更能展示进步。”你同时运用了数学、体育和评估能力。
10. Integrated Scenario: Planning a School Sports Day | 综合情景：策划校园运动会
Imagine your class is organising a mini Sports Day. You need to design a 4 × 100 m relay event involving a run, a jump and a throw. The available space is a rectangular field 80 m long and 40 m wide. You must allocate lanes of 1 m width and ensure enough spacing for safety.
假设你的班级正在组织一场小型运动会。你需要设计一个 4×100 米接力项目，其中包含跑步、跳跃和投掷。可用场地是一个长 80 米、宽 40 米的矩形区域。你需要分配 1 米宽的跑道，并确保足够的安全间距。
Integrated question: ‘Calculate the maximum number of 1 m wide lanes that can fit across the 40 m width if a 2 m safety walkway must be left on each side. Then draw a simple map of the field with a 100 m running straight, a long jump pit and a throwing circle. Explain how friction from different surfaces might affect running speed and jumping take-off.’ This brings together maths, geography, physics and design.
综合题：“如果两侧必须各留 2 米宽的安全通道，计算 40 米宽度的场地最多可容纳多少条 1 米宽的跑道。然后画一幅简图，标出 100 米直道、一个跳远沙坑和一个投掷圈。解释不同表面的摩擦力会如何影响跑步速度和跳跃起跳。”这融合了数学、地理、物理和设计思维。
11. Sample Integrated Questions & Answers | 综合题型示例与解答
Below are three quick integrated questions that mix subjects. Try them on your own or with a partner.
以下是三个混合多学科的快速综合题。你可以自己或与同伴一起尝试。
Question 1: A 12-year-old swimmer completes 20 laps of a 25 m pool. (a) Calculate the total distance swum in kilometres. (b) Her average speed is 1.8 m/s. How many seconds does the whole swim take? (c) Explain how chlorine in the pool water helps keep it hygienic, linking to Year 7 Science. Answer: (a) 20 × 25 = 500 m = 0.5 km. (b) Time = distance ÷ speed = 500 ÷ 1.8 ≈ 277.8 seconds. (c) Chlorine kills bacteria and viruses in the water, breaking down their cell walls, which prevents infections among swimmers.
问题 1：一名 12 岁的游泳者在 25 米泳池中完成 20 圈。(a) 计算总游泳距离，以千米为单位。(b) 她的平均速度是 1.8 米/秒，整个游泳需要多少秒？(c) 结合 Year 7 科学，解释泳池水中的氯如何保持卫生。答案：(a) 20×25 = 500 米 = 0.5 km。(b) 时间 = 距离÷速度 = 500÷1.8 ≈ 277.8 秒。(c) 氯能杀死水中的细菌和病毒，破坏其细胞壁，从而防止游泳者感染。
Question 2: While playing basketball, you notice your breathing rate increases from 15 breaths/min at rest to 35 breaths/min during a game. Calculate the percentage increase. Why does your body need to remove more CO₂ during exercise? Answer: Increase = 35 – 15 = 20 breaths/min. Percentage increase = (20 ÷ 15) × 100 = 133.3%. During exercise, muscles produce more CO₂ as a waste product of respiration; faster breathing helps expel CO₂ and take in more O₂.
问题 2：打篮球时，你注意到呼吸频率从休息时的 15 次/分钟上升到比赛中的 35 次/分钟。计算增长百分比。为什么运动时身体需要排出更多二氧化碳？答案：增长量 = 35 – 15 = 20 次/分钟。增长百分比 = (20÷15)×100 = 133.3%。运动时肌肉通过呼吸作用产生更多二氧化碳作为废物；加快呼吸有助于排出二氧化碳并摄入更多氧气。
Question 3: A student does a long jump. Her take-off angle is 20°, and her horizontal velocity is 5 m/s. The vertical component of velocity can be estimated by v × sin(θ). Using a calculator, find the vertical component. Then name the main muscle group that extends the knee during take-off and identify the joint involved. Answer: Vertical component = 5 × sin(20°) = 5 × 0.342 ≈ 1.71 m/s. The quadriceps extend the knee; the joint is the knee joint (hinge).
问题 3：一名学生进行跳远。她的起跳角度为 20°，水平速度为 5 m/s。垂直分速度可用 v × sin(θ) 估算。用计算器求出垂直分速度。然后说出起跳时伸展膝关节的主要肌肉群，并指出所涉及的关节。答案：垂直分速度 = 5×sin(20°) = 5×0.342 ≈ 1.71 m/s。股四头肌伸展膝关节；关节是膝关节（铰链关节）。
