1. Paper Overview | 试卷结构概览

A typical Cambridge IGCSE Physical Education unit test contains a mixture of short-answer questions, data-response items, and one or two extended-response questions. Marks are usually spread across four assessment objectives: knowledge, application, analysis, and evaluation.

典型的剑桥 IGCSE 体育单元测试包含简答题、数据题，以及一两道拓展题。分值通常分布在四个评估目标上：知识、应用、分析和评价。

In this mock paper, the marks are weighted as follows:

本模拟卷的分值分布如下：

Section | 部分	Content | 内容	Marks | 分值
A | 部分 A	Anatomy and Physiology | 解剖与生理	40 | 40 分
B | 部分 B	Health, Fitness and Training | 健康、体适能与训练	30 | 30 分
C | 部分 C	Skill Acquisition and Psychology | 技能习得与心理学	20 | 20 分
D | 部分 D	Social and Cultural Influences | 社会文化影响	10 | 10 分

To score well, candidates must use precise anatomical terms, link structure to function, and provide practical sporting examples. A vague answer such as ‘it helps the body’ almost always earns zero marks.

要想获得高分，考生必须使用准确的解剖学术语，将结构与功能联系起来，并提供具体的运动实例。像“它帮助身体”这样的模糊回答几乎总是得零分。

2. Skeletal System | 骨骼系统

Question: State three functions of the skeleton and, for each function, identify one named bone or group of bones that supports your answer.

题目：说出骨骼的三项功能，并针对每项功能指出一个与该功能相关的骨或骨群。

Model answer: Support is provided by the vertebral column, which holds the body upright. Protection is shown by the cranium protecting the brain. Movement is enabled by long bones such as the femur, which acts as a lever when muscles pull on it. Mineral storage occurs in bones such as the ribs, which store calcium and phosphorus. Blood cell production takes place in the bone marrow of flat bones like the pelvis.

参考答案：支撑功能由脊柱提供，脊柱使身体保持直立。保护功能体现在颅骨保护大脑。运动功能由股骨等长骨实现，肌肉牵拉时股骨作为杠杆。矿物质储存发生在肋骨等骨骼中，储存钙和磷。造血发生在骨盆等扁骨的骨髓中。

Examiner comment: A common error is to write ‘the skeleton supports the body’ with no named structure. Always add a bone or region to make the point specific. Also, do not confuse mineral storage with blood cell production; they are separate functions.

考官点评：常见错误是只写“骨骼支撑身体”，却没有指出具体结构。一定要加上骨骼或部位使答案具体。同时，不要将矿物质储存与造血混淆，它们是不同的功能。

3. Muscular System | 肌肉系统

Question: Describe how a pair of antagonistic muscles works to bend and straighten the elbow. Use the terms agonist and antagonist in your answer.

题目：描述一对拮抗肌如何使肘关节弯曲和伸直。回答中要使用主动肌和拮抗肌术语。

Model answer: When bending the elbow, the biceps brachii is the agonist because it contracts and shortens. The triceps brachii is the antagonist and relaxes to allow movement. When straightening the elbow, the roles reverse: the triceps brachii contracts as the agonist, while the biceps brachii relaxes as the antagonist.

参考答案：屈肘时，肱二头肌是主动肌，因为它收缩并缩短。肱三头肌是拮抗肌，放松以允许运动。伸肘时，角色互换：肱三头肌作为主动肌收缩，肱二头肌则作为拮抗肌放松。

Examiner comment: Candidates often describe the biceps as always being the agonist, but this is only true for flexion. For extension, the triceps must be named as the agonist. Also, the term ‘contracts’ should be paired with ‘agonist’, not used loosely for both muscles at the same time.

考官点评：考生经常把肱二头肌说成始终是主动肌，但这只在屈曲时成立。伸展时，必须指出肱三头肌是主动肌。此外，“收缩”一词应与“主动肌”搭配使用，不能同时笼统地用于两块肌肉。

4. Respiratory System | 呼吸系统

Question: Define tidal volume and vital capacity. Explain one reason why vital capacity may be higher in a trained endurance athlete than in an untrained person.

题目：定义潮气量和肺活量。解释为什么训练有素的耐力运动员肺活量可能高于未经训练者。

Model answer: Tidal volume is the volume of air breathed in or out during normal, restful breathing. Vital capacity is the maximum volume of air that can be exhaled after a maximum inhalation. A trained endurance athlete may develop stronger respiratory muscles, including the diaphragm and intercostal muscles, allowing a greater expansion of the chest cavity and therefore a larger vital capacity.

参考答案：潮气量是平静呼吸时每次吸入或呼出的空气量。肺活量是最大吸气后能呼出的最大空气量。训练有素的耐力运动员呼吸肌（包括膈肌和肋间肌）更强壮，能使胸腔扩张更大，因此肺活量更大。

Examiner comment: Do not confuse tidal volume with vital capacity. Tidal volume is at rest, whereas vital capacity is a maximum measurement. Also, always link the physiological change to a functional benefit: stronger respiratory muscles increase lung expansion, not just ‘better lungs’.

考官点评：不要混淆潮气量和肺活量。潮气量是安静状态下的指标，而肺活量是最大测量值。此外，始终将生理变化与功能益处联系起来：呼吸肌更强壮会增加肺部扩张，而不只是“肺更好”。

5. Circulatory System | 循环系统

Question: Starting from the vena cava, describe the correct order of blood flow through the heart and lungs until it leaves the aorta.

题目：从腔静脉开始，描述血液流经心脏和肺，直到离开主动脉的正确顺序。

Model answer: Deoxygenated blood enters the right atrium via the vena cava. It passes through the right atrioventricular valve into the right ventricle. The right ventricle pumps blood through the pulmonary artery to the lungs, where gas exchange occurs. Oxygenated blood returns through the pulmonary vein to the left atrium. It then passes through the left atrioventricular valve into the left ventricle, which pumps blood out through the aorta to the body.

参考答案：脱氧血经腔静脉进入右心房，通过右房室瓣进入右心室。右心室将血液经肺动脉泵入肺，在肺内进行气体交换。含氧血经肺静脉回到左心房，然后通过左房室瓣进入左心室，左心室将血液经主动脉泵出到全身。

Examiner comment: Sequencing errors are the most common problem. Many candidates place the pulmonary vein before the pulmonary artery or reverse the left and right sides. Draw and label the heart at home; exam success in this topic starts with a clear mental map of the four chambers.

考官点评：顺序错误是最常见的问题。许多考生把肺静脉放在肺动脉之前，或把左右两侧弄反。建议在家绘制并标注心脏结构；在这一主题上取得好成绩，首先要对四个腔室有清晰的思维导图。

6. Energy Systems | 能量系统

Question: Compare the main energy supply for a 100 m sprinter with that for a marathon runner. Refer to the energy systems involved, fuel sources, and by-products.

题目：比较 100 米短跑运动员与马拉松运动员的主要能量供应。回答中要涉及所动用的能量系统、燃料来源和副产物。

Model answer: A 100 m sprinter mainly uses the ATP-PC system and lactic acid anaerobic system because energy is needed very quickly and oxygen cannot be delivered fast enough. The fuel is stored phosphocreatine and glucose, and the by-products include inorganic phosphate and lactic acid. A marathon runner mainly uses the aerobic system, which breaks down glucose and fatty acids in the presence of oxygen, producing carbon dioxide, water, and a large yield of ATP.

参考答案：100 米短跑运动员主要使用 ATP-PC 系统和乳酸无氧系统，因为能量需求非常迅速，氧气无法足够快地输送到肌肉。燃料是储存的磷酸肌酸和葡萄糖，副产物包括无机磷酸盐和乳酸。马拉松运动员主要使用有氧系统，在氧气存在下分解葡萄糖和脂肪酸，产生二氧化碳、水和大量 ATP。

Examiner comment: Avoid saying a sprinter uses no oxygen at all; at the start there is always some aerobic contribution, but it is minimal and cannot meet the immediate demand. Use the correct system names rather than vague terms like ‘short-term energy’.

考官点评：不要说短跑运动员完全不使用氧气；起跑时总会有少量有氧参与，但极少且无法满足即时需求。要使用正确的系统名称，而不是“短期能量”等模糊说法。

7. Health and Fitness | 健康与体适能

Question: Define health and fitness. Using an example, explain how a person can be physically fit but not necessarily in complete health.

题目：定义健康和体适能。举例说明一个人如何可能体适能良好，但未必完全健康。

Model answer: Health is a state of complete physical, mental, and social well-being, not merely the absence of disease. Fitness is the ability to meet the demands of the environment. A professional rugby player may have excellent cardiovascular endurance, strength, and speed, but could be suffering from depression or a long-term injury. That player would be fit in a physical sense but not in complete health because mental or social well-being is affected.

参考答案：健康是身体、心理和社会三方面的完全良好状态，而不仅仅是没有疾病。体适能是满足环境需求的能力。一名职业橄榄球运动员可能拥有极好的心血管耐力、力量和速度，但可能患有抑郁症或长期伤病。该运动员在身体层面是体适能良好的，但并非完全健康，因为心理或社会健康受到影响。

Examiner comment: Many candidates define health only as ‘not being ill’. Cambridge expects the full definition, including physical, mental, and social well-being. For the example, name a specific fitness component and a specific health condition rather than writing generally.

考官点评：许多考生仅将健康定义为“没有生病”。剑桥要求完整定义，包括身体、心理和社会健康。举例时，要说出具体的体适能要素和具体的健康问题，而不是泛泛而谈。

8. Training Principles | 训练原则

Question: Explain the FITT principle and apply it to a 16-year-old sprinter who wants to improve cardiovascular endurance.

题目：解释 FITT 原则，并将其应用于一名希望提高心血管耐力的 16 岁短跑运动员。

Model answer: FITT stands for Frequency, Intensity, Time, and Type. Frequency is how often training takes place, intensity is how hard the athlete works, time is how long each session lasts, and type is the method of training used. For a 16-year-old sprinter improving cardiovascular endurance, a suitable programme could involve continuous training 3 to 5 times per week, at 60% to 80% of maximum heart rate, for 20 to 40 minutes per session.

参考答案：FITT 代表频率、强度、时间和类型。频率指训练进行的次数，强度指运动员用力的程度，时间指每次训练的时长，类型指所用的训练方法。对于提高心血管耐力的 16 岁短跑运动员，合适的计划可以是每周进行 3 至 5 次持续训练，强度为最大心率的 60% 至 80%，每次 20 至 40 分钟。

Examiner comment: The most common error is to describe FITT without applying it to the stated athlete. Always include numbers or methods that match the scenario. Also, remember that cardiovascular endurance is best improved by aerobic training types such as continuous, fartlek, or interval training, not by heavy strength work alone.

考官点评：最常见的错误是只描述 FITT，却没有将其应用到题目给出的运动员身上。始终要包含与情境匹配的数字或方法。此外，要记住心血管耐力最好通过持续训练、法特莱克训练或间歇训练等有氧训练来提高，而不是单靠大重量力量训练。

9. Skill Acquisition | 技能习得

Question: Classify a basketball free throw on three different skill continua. Justify each classification.

题目：从三个不同的技能连续体对篮球罚球进行分类，并说明理由。

Model answer: A basketball free throw is a closed skill because the environment is stable and predictable; the player performs it in a fixed position without opponents moving during the shot. It is a self-paced skill because the performer controls when to start the action. It is predominantly a gross motor skill because it requires large muscle groups in the legs and arms to produce the shot, although it also requires fine control for accuracy.

参考答案：篮球罚球是一项封闭性技能，因为环境稳定且可预测；球员在固定位置完成动作，投篮时没有对手移动干扰。它是一项自我节奏技能，因为运动员可以控制动作何时开始。它主要属于粗大运动技能，因为需要腿部和手臂的大肌群发力完成投篮，尽管它也要求精细控制以保证准确性。

Examiner comment: Justification is as important as classification. Writing ‘it is closed’ without saying why the environment is stable will not earn full marks. If you argue the skill has fine elements, state the large-muscle action as well so the answer is balanced.

考官点评：分类后的理由同等重要。只写“它是封闭性技能”而不说明环境为何稳定，无法获得满分。如果你认为该技能具有精细成分，也要说明大肌群的动作，使答案更加全面。

10. Sport Psychology | 运动心理学

Question: Discuss two ways a coach can increase intrinsic motivation in young performers.

题目：讨论教练可以通过哪两种方式提高年轻运动员的内在动机。

Model answer: One way is to provide choice and involve performers in decision-making, such as letting them choose between two warm-up activities. This increases autonomy and therefore intrinsic motivation. Another way is to focus on mastery and personal improvement rather than only winning. A coach might set individual skill targets, such as improving a personal best in the long jump, which helps the performer feel competent and satisfied from within.

参考答案：一种方法是提供选择并让运动员参与决策，例如让他们在两种热身活动中选择一种。这能增强自主感，从而提高内在动机。另一种方法是关注任务掌握和个人进步，而不是只关注胜负。教练可以设置个人技能目标，例如提高跳远个人最好成绩，这有助于运动员从内心感受到能力和满足感。

Examiner comment: Intrinsic motivation comes from internal drives such as enjoyment, pride, and personal challenge. Candidates often incorrectly use trophies or money as examples, which are extrinsic rewards. Keep the distinction clear and always explain how the method increases internal satisfaction.

考官点评：内在动机来自内部驱动力，如乐趣、自豪感和个人挑战。考生经常错误地使用奖杯或金钱作为例子，这些属于外在奖励。要清楚区分，并始终解释该方法如何提升内在满足感。

11. Social and Cultural Influences | 社会文化影响

Question: Explain two socio-cultural factors that may affect participation in physical activity.

题目：解释可能影响体育参与的两个社会文化因素。

Model answer: Age can affect participation because opportunities and physical capabilities change over the lifespan. For example, many older adults stop playing high-impact contact sports and may instead choose swimming or walking. Gender can also affect participation because cultural expectations in some societies may discourage girls or women from taking part in certain sports, reducing access and confidence.

参考答案：年龄会影响参与，因为机会和身体能力随生命周期变化。例如，许多老年人不再参加高冲击性接触运动，而可能选择游泳或步行。性别也会影响参与，因为某些社会的文化期望可能不鼓励女孩或女性参加某些运动，从而减少了参与机会和信心。

Examiner comment: Do not merely list factors such as ‘age’ or ‘gender’. You must explain how each factor influences participation and give a relevant example. Socio-economic status and access to facilities are also acceptable if you explain the cause-and-effect relationship.

考官点评：不要只列出“年龄”或“性别”等因素。必须解释每个因素如何影响参与，并给出相关例子。如果能解释因果关系，社会经济地位和设施可及性也是可接受的答案。

12. Exam Technique Summary | 答题技巧总结

The most effective way to improve marks is to match your answer to the command word. ‘State’ requires a short factual response, ‘describe’ needs detail of what happens, and ‘explain’ requires a reason or mechanism. ‘Evaluate’ asks for advantages and limitations before a judgement.

提高分数最有效的方法是让答案与指令词匹配。“State”要求简短的事实回答，“describe”需要描述发生了什么，“explain”要求给出原因或机制，“evaluate”则要求在作出判断前分析优点和局限性。

Always use precise terminology from the syllabus, such as agonist, antagonistic pair, tidal volume, aerobic system, intrinsic motivation, and closed skill. Connect each term to a named sporting example. Avoid one-word answers when the mark allocation is more than one mark.

始终使用大纲中的准确术语，例如主动肌、拮抗肌对、潮气量、有氧系统、内在动机和封闭性技能。将每个术语与具体的运动实例联系起来。当分值大于 1 分时，避免只回答一个词。

Finally, manage your time by reading the question twice, underlining key command words, and planning extended responses briefly before writing. A well-structured answer with clear scientific logic will always outperform a long but disconnected paragraph.

最后，通过阅读题目两遍、划出关键指令词、在写作前简要规划拓展回答来管理时间。结构清晰、科学逻辑明确的答案永远优于冗长但条理不清的段落。
