1. Overview of the Mock Paper | 模拟卷概览与分析
A WJEC Year 9 PE mock paper usually consists of three sections: Section A features multiple-choice questions testing basic recall; Section B contains short-answer questions that require explanations of concepts like muscles, bones, and fitness components; Section C includes one or two extended writing tasks where you must apply knowledge to sporting scenarios. Time management is essential: spend about 1 minute per mark.
WJEC 九年级体育模拟卷通常由三部分组成：A 部分是选择题，考查基础知识记忆；B 部分包含简答题，要求解释肌肉、骨骼和体能组成等概念；C 部分有一到两个扩展写作任务，你需要将知识应用到运动场景中。时间管理至关重要：每分值大约花费 1 分钟。
Common command words include ‘identify’, ‘describe’, ‘explain’, and ‘evaluate’. For ‘explain’ questions, always state a reason or link to an example. For extended writing, use PEEL paragraphs (Point, Evidence, Explanation, Link) to structure your answer and show depth of understanding.
常见的指令词有 “identify”（识别）、“describe”（描述）、“explain”（解释）和 “evaluate”（评估）。对于 “解释” 类题目，务必陈述原因或结合实例。在扩展写作中，使用 PEEL 段落结构（观点、证据、解释、联系）来组织答案，展现理解的深度。
2. Skeletal System and Functions | 骨骼系统及其功能
The skeleton has five critical functions: support, protection, movement, mineral storage, and blood cell production. You should be able to label key bones such as the cranium, clavicle, scapula, humerus, radius, ulna, pelvis, femur, patella, tibia, and fibula.
骨骼有五个关键功能：支撑、保护、运动、矿物质储存和血细胞生成。你需要能够标记主要骨骼，如颅骨、锁骨、肩胛骨、肱骨、桡骨、尺骨、骨盆、股骨、髌骨、胫骨和腓骨。
Synovial joints are freely movable and include the hinge joint (elbow, knee) and ball-and-socket joint (shoulder, hip). Articular cartilage reduces friction, synovial fluid lubricates the joint, and ligaments connect bone to bone. Tendons attach muscle to bone, enabling movement when muscles contract.
滑膜关节可自由活动，包括屈戍关节（肘、膝）和球窝关节（肩、髋）。关节软骨减少摩擦，滑液润滑关节，韧带连接骨与骨。肌腱将肌肉附着在骨骼上，当肌肉收缩时产生运动。
Example exam question: ‘Describe the role of the skeleton in protecting vital organs.’ A good answer: ‘The cranium protects the brain from impact, the rib cage shields the heart and lungs, and the vertebral column surrounds the spinal cord.’
考试例题：“描述骨骼在保护重要器官方面的作用。” 优秀答案是：“颅骨保护大脑免受撞击，胸廓保护心脏和肺，脊柱包围脊髓。”
3. Major Muscles and Movement Analysis | 主要肌肉与动作分析
You must know the location and action of key voluntary muscles: biceps flexes the arm at the elbow, triceps extends the arm, quadriceps extends the leg at the knee, hamstrings flex the knee, gastrocnemius points the toes (plantar flexion), and abdominals flex the trunk. Muscles work in pairs — the agonist (prime mover) contracts while the antagonist relaxes.
你必须知道主要随意肌的位置和作用：肱二头肌使手臂在肘部屈曲，肱三头肌使手臂伸展，股四头肌伸展膝部，腘绳肌屈曲膝部，腓肠肌使脚尖下压（跖屈），腹肌使躯干屈曲。肌肉成对工作——主动肌（原动肌）收缩，拮抗肌放松。
When performing a bicep curl during the lifting phase, the biceps brachii acts as the agonist and the triceps brachii serves as the antagonist. During the lowering phase, the roles reverse. This coordinated action allows smooth, controlled movement.
在弯举动作的举起阶段，肱二头肌为主动肌，肱三头肌为拮抗肌。在放下阶段，角色互换。这种协调作用使得动作流畅、可控。
Isometric contractions occur when the muscle length stays the same, e.g., holding a plank position. Isotonic contractions involve a change in length, and can be concentric (muscle shortens) or eccentric (muscle lengthens under tension). These details are often tested.
等长收缩发生在肌肉长度不变时，例如平板支撑。等张收缩涉及长度变化，可分为向心收缩（肌肉缩短）和离心收缩（肌肉在张力下拉长）。这些细节常被考查。
4. Cardiovascular Responses to Exercise | 运动时心血管系统的响应
Immediate effects of exercise on the cardiovascular system include increased heart rate, increased stroke volume, and elevated cardiac output. Heart rate (HR) is the number of beats per minute; stroke volume (SV) is the amount of blood pumped per beat; cardiac output (Q) = HR × SV.
运动对心血管系统的即时效应包括心率加快、每搏输出量增加和心输出量升高。心率（HR）是每分钟心跳次数；每搏输出量（SV）是每搏泵出的血量；心输出量（Q）= HR × SV。
Cardiac Output (Q) = Heart Rate (HR) × Stroke Volume (SV)
心输出量 (Q) = 心率 (HR) × 每搏输出量 (SV)
Regular training leads to long-term adaptations: resting heart rate decreases because the heart becomes more efficient; stroke volume increases; and capillaries around muscles become denser, improving oxygen delivery. These changes benefit overall endurance.
经常训练会产生长期适应：静息心率下降，因为心脏效率提高；每搏输出量增加；肌肉周围的毛细血管更加密集，改善氧气输送。这些变化有益于整体耐力。
During exercise, blood is redistributed from non-essential areas (such as the digestive system) to the working muscles. This is controlled by vasodilation (widening of blood vessels) and vasoconstriction (narrowing). A typical exam question asks you to explain why the vascular shunt mechanism is important.
运动期间，血液从非关键部位（如消化系统）重新分配到工作中的肌肉。这由血管舒张（血管扩张）和血管收缩（血管变窄）控制。典型考题要求你解释血管分流机制的重要性。
5. Respiratory System and Gaseous Exchange | 呼吸系统与气体交换
The respiratory system brings oxygen into the body and removes carbon dioxide. Air travels through the nose/mouth, trachea, bronchi, bronchioles, and finally reaches the alveoli — tiny air sacs where gas exchange occurs. The diaphragm and intercostal muscles control breathing.
呼吸系统将氧气带入身体并排出二氧化碳。空气经过鼻/口、气管、支气管、细支气管，最终到达肺泡——进行气体交换的微小小气囊。膈肌和肋间肌控制呼吸。
During exercise, tidal volume (the amount of air inhaled per breath) and breathing rate increase, leading to a higher minute ventilation. Minute ventilation = tidal volume × breathing rate. This ensures more oxygen is delivered to the blood and more CO₂ is removed.
运动期间，潮气量（每次呼吸吸入的空气量）和呼吸频率增加，导致更高的每分通气量。每分通气量 = 潮气量 × 呼吸频率。这确保更多氧气输送到血液，更多二氧化碳被排出。
Gaseous exchange relies on diffusion. Oxygen moves from a high concentration in the alveoli into the blood (low concentration), while CO₂ diffuses from the blood into the alveoli to be exhaled. The alveoli have thin walls and a large surface area to maximise this process.
气体交换依赖于扩散。氧气从肺泡高浓度处扩散进血液（低浓度），同时二氧化碳从血液扩散到肺泡呼出。肺泡壁极薄、表面积大，以最大化这一过程。
6. Components of Health-Related Fitness | 健康相关的体能组成
There are five health-related fitness components: cardiovascular endurance, muscular strength, muscular endurance, flexibility, and body composition. Each can be measured by standard fitness tests. For example, the Cooper 12-minute run test assesses cardiovascular endurance, and the handgrip dynamometer test measures muscular strength.
健康相关的体能组成为五种：心肺耐力、肌肉力量、肌肉耐力、柔韧性和身体成分。每一项都可通过标准体能测试测量。例如，库珀 12 分钟跑测试评估心肺耐力，握力计测试测量肌肉力量。
Muscular endurance is often assessed through the sit-up test or press-up test (max in one minute). Flexibility can be measured by the sit-and-reach test. Body composition is usually evaluated via BMI or skinfold calipers. In the exam, you may be asked to justify the choice of a test for a particular sport.
肌肉耐力通常通过仰卧起坐测试或俯卧撑测试（一分钟内最多次数）评估。柔韧性可通过坐位体前屈测试测量。身体成分通常用 BMI 或皮褶卡尺评估。考试中，你可能需要说明为某项运动选择测试的理由。
Skill-related fitness components, such as agility, balance, coordination, power, reaction time, and speed, are also part of the WJEC specification. A tennis player needs high agility and coordination; a sprinter relies on speed and power. Always link components to sporting examples.
技能相关的体能组成，如灵敏性、平衡能力、协调性、爆发力、反应时间和速度，也属于 WJEC 大纲范畴。网球运动员需要高灵敏性和协调性；短跑运动员依赖速度和爆发力。务必结合运动实例。
7. Principles of Training (FITT) | 训练原则（FITT）
The FITT principle helps design an effective exercise programme: Frequency (how often), Intensity (how hard), Time (duration), and Type (kind of exercise). To improve cardiovascular fitness, a runner might train 3 times a week (frequency), at 70% of max heart rate (intensity), for 30 minutes (time), using jogging (type).
FITT 原则有助于设计有效的锻炼计划：频率（多频繁）、强度（多努力）、时间（持续时间）和类型（运动种类）。为了提高心肺体能，跑步者可能每周训练 3 次（频率），以最大心率的 70%（强度），持续 30 分钟（时间），采用慢跑（类型）。
Other key principles include specificity (training must match the sport or goal), progressive overload (gradually increasing demands to force adaptation), reversibility (use it or lose it), and tedium (variety prevents boredom). A long-answer question might ask you to explain how a coach could apply these principles.
其他关键原则包括专项性（训练必须匹配运动或目标）、渐进超负荷（逐步增加负荷以促进适应）、可逆性（不用则废）和趣味性（多样性可避免枯燥）。长答题可能会要求你解释教练如何应用这些原则。
Rest and recovery are equally important. Overtraining can lead to injury, fatigue, and decreased performance. A training programme should always include rest days and appropriate sleep, which allows muscles to repair and adapt.
休息和恢复同样重要。过度训练会导致受伤、疲劳和表现下降。训练计划应始终包含休息日和充足的睡眠，让肌肉得以修复和适应。
8. Nutrition and Hydration for Performance | 运动表现所需的营养与水分
A balanced diet for athletes includes macronutrients: carbohydrates (main energy source), proteins (muscle repair and growth), and fats (slow-release energy). Micronutrients include vitamins and minerals such as iron (oxygen transport) and calcium (bone strength). Hydration is vital; even 2% dehydration can impair performance.
运动员的均衡饮食包括宏量营养素：碳水化合物（主要能量来源）、蛋白质（肌肉修复和生长）和脂肪（缓慢释放的能量）。微量营养素包括维生素和矿物质，如铁（氧气运输）和钙（骨骼强度）。水分至关重要；即使 2% 的脱水也会影响表现。
The timing of nutrition matters. A pre-event meal 2-3 hours before competition should be high in complex carbohydrates and low in fat and fibre to avoid stomach discomfort. During prolonged exercise, isotonic drinks help replenish fluids, electrolytes, and carbohydrates.
营养摄入时机也很重要。赛前 2-3 小时的正餐应富含复合碳水化合物、低脂肪和低纤维，以避免肠胃不适。长时间运动期间，等渗饮料有助于补充水分、电解质和碳水化合物。
Carbohydrate loading can be used before endurance events to maximise glycogen stores. Post-exercise, a combination of protein and carbohydrates within 30 minutes supports optimal recovery. In the exam, you may be given a diet scenario and asked to suggest improvements.
耐力赛事之前可使用糖原负荷法，以最大化糖原储备。运动后 30 分钟内摄入蛋白质和碳水化合物组合有助于最佳恢复。考试中，可能会给出某个饮食情境，请你提出改进建议。
9. Mental Preparation and Goal Setting | 心理准备与目标设定
Mental preparation techniques help athletes control arousal and focus. Common methods include visualisation (mental imagery of successful performance), positive self-talk, and relaxation techniques like deep breathing. These reduce anxiety and improve confidence.
心理准备技巧有助于运动员控制唤醒水平和专注力。常用方法包括视觉化（对成功表现的心理想象）、积极自我对话和深呼吸等放松技术。这些能减少焦虑，提高自信心。
Goal setting using the SMART principle is a key topic. Goals should be Specific, Measurable, Achievable, Relevant, and Time-bound. For example, instead of ‘get fit’, a SMART goal is ‘run 5 km in 25 minutes within 8 weeks’. This provides clear direction and motivation.
运用 SMART 原则设定目标是重要主题。目标应具体（Specific）、可测量（Measurable）、可达成（Achievable）、相关（Relevant）和有时限（Time-bound）。例如，比起“变得更健康”，SMART 目标是“在 8 周内以 25 分钟跑完 5 公里”。这能提供明确的方向和动力。
Performance goals focus on personal improvement, while outcome goals focus on winning. Performance goals (e.g., improving a personal best) are more effective for maintaining motivation, as they are under the athlete’s control. A question may ask you to evaluate the benefits of different goal types.
表现目标聚焦于个人进步，结果目标聚焦于获胜。表现目标（如提高个人最佳成绩）更能维持动力，因为它由运动员掌控。题目可能要求你评估不同类型目标的益处。
10. Injury Prevention and Warm-Up/Cool-Down | 伤害预防与热身/整理活动
A proper warm-up gradually increases heart rate, body temperature, and flexibility, preparing the body for intense activity. It should have three stages: pulse raiser (light jogging), stretching (dynamic movements), and sport-specific drills. A cool-down brings the body back to resting state and aids removal of lactic acid.
适当的热身逐渐提高心率、体温和柔韧性，为高强度活动做好准备。它应包括三个阶段：提升心率练习（轻量慢跑）、拉伸（动态动作）和专项练习。整理活动使身体恢复至安静状态，并有助于清除乳酸。
Key causes of sports injuries include incorrect technique, insufficient warm-up, overuse, and inappropriate equipment. Wearing shin pads in football, using the correct footwear, and following the rules of the game are all important preventive measures.
运动损伤的主要原因包括错误技术、热身不充分、过度使用和装备不当。足球运动中穿戴护腿板、使用合适的鞋类以及遵守比赛规则，都是重要的预防措施。
If a soft tissue injury (like a sprain) occurs, the RICE protocol is recommended: Rest, Ice, Compression, Elevation. Rest prevents further damage, ice reduces swelling, compression limits fluid build-up, and elevation drains fluid away from the injury. Always demonstrate clear understanding of each step.
若发生软组织损伤（如扭伤），建议采用 RICE 方案：休息（Rest）、冰敷（Ice）、加压（Compression）、抬高（Elevation）。休息防止进一步受伤，冰敷减轻肿胀，加压限制积液，抬高帮助引流体液。务必清晰理解每一步骤。
