模拟考试是准备 Year 7 WJEC 体育单元测试的强大工具。它们模拟真实考试的形式，涵盖健康、体能组成要素、训练原则和身体系统等主题。本文逐题解析一份典型的模拟卷，讲解正确答案和背后的概念。通过阅读这份解析，你将加深理解，并学会如何有效应用知识。
1. Health vs Fitness: Key Definitions | 健康与体能：关键定义
One of the most common questions asks you to define health and fitness. Health is a state of complete physical, mental, and social well-being, not merely the absence of disease. Fitness, on the other hand, is the ability to meet the demands of the environment. For example, a person might be physically fit but still suffer from stress (poor mental health). Understanding this distinction is vital.
最常见的问题之一是要求你定义健康和体能。健康是一种身体、心理和社交都完好的状态，而不仅仅是没有疾病。体能则是满足环境需求的能力。例如，一个人可能身体健康，但仍然遭受压力（心理不健康）。理解这一区别至关重要。
Typical mock question: 'Define health and give an example of how a person can be healthy but not fit.' Answer: Health is complete well-being; a person may have no illness but lack the cardiovascular endurance to run a mile, so they are healthy but not fit. Always link your example to a component of fitness.
典型模拟题：'定义健康，并举例说明一个人可能健康但不健康。' 答案：健康是完整的良好状态；一个人可能没有疾病，但缺乏跑一英里的心血管耐力，所以他们健康但不健康。始终将你的例子与一项体能组成要素联系起来。
2. Components of Fitness: Health-Related | 健康相关体能组成
WJEC expects you to know the five health-related components: cardiovascular endurance, muscular endurance, muscular strength, flexibility, and body composition. A common task is matching a sport to the most important component. For instance, a marathon runner relies on cardiovascular endurance, while a gymnast needs flexibility and strength.
WJEC 要求你了解五个健康相关体能组成：心血管耐力、肌肉耐力、肌肉力量、柔韧性和身体成分。一个常见的任务是匹配运动与最重要的组成要素。例如，马拉松运动员依赖心血管耐力，而体操运动员需要柔韧性和力量。
Mock question: 'Identify the health-related component most needed for a swimmer in a 1500m race.' Answer: Cardiovascular endurance, because the event is long-duration and requires the heart and lungs to supply oxygen to working muscles. Explanations must mention the link to the activity's demands.
模拟题：'指出1500米游泳运动员最需要的健康相关体能组成。' 答案：心血管耐力，因为该项是长时间运动，需要心肺向工作肌肉供应氧气。解释必须提及与活动需求的联系。
Use this table to revise the definitions:
| Component | Definition | Sport Example |
|---|---|---|
| Cardiovascular Endurance | Ability of heart and lungs to supply oxygen over time | Long-distance running |
| Muscular Endurance | Ability of a muscle to repeat contractions without fatigue | Rowing |
| Muscular Strength | Maximum force a muscle can exert | Weightlifting |
| Flexibility | Range of motion around a joint | Gymnastics |
| Body Composition | Percentage of fat, muscle, and bone in the body | Sumo wrestling |
中文翻译：心血管耐力：心肺长时间供氧的能力；肌肉耐力：肌肉重复收缩而不疲劳的能力；肌肉力量：肌肉产生的最大力量；柔韧性：关节活动范围；身体成分：身体中脂肪、肌肉和骨骼的比例。
3. Components of Fitness: Skill-Related | 技能相关体能组成
Skill-related components include agility, balance, coordination, power, reaction time, and speed. These are often tested through multiple-choice or scenario questions. For example, a tennis player returning a serve needs good reaction time and coordination. Make sure you can define each and give a sport example.
技能相关体能组成包括敏捷性、平衡、协调、爆发力、反应时间和速度。这些通常通过选择题或情景题来测试。例如，网球运动员接发球需要良好的反应时间和协调性。确保你能定义每项并给出运动实例。
Mock question: 'A basketball player dodges a defender and changes direction quickly. Which skill-related component is being used?' Correct answer: Agility. Many students confuse agility with speed. Agility is the ability to change direction at speed; speed is just moving quickly in a straight line. Understand the difference.
模拟题：'一名篮球运动员躲避防守队员并快速变换方向。此时使用了哪项技能相关体能组成？' 正确答案：敏捷性。许多学生将敏捷性与速度混淆。敏捷性是在快速移动中改变方向的能力；速度只是直线快速移动。理解区别。
4. Principles of Training: SPORT & FITT | 训练原则：SPORT 和 FITT 原则
Training principles guide how to improve fitness. SPORT stands for Specificity, Progression, Overload, Reversibility, and Tedium. A common question asks you to apply these to a training programme. For overload, remember the FITT principle: Frequency, Intensity, Time, and Type. For example, to progressively overload a runner, you could increase the distance (time) or run at a higher speed (intensity).
训练原则指导如何改善体能。SPORT 代表专项性、渐进性、超负荷、可逆性和枯燥性。常见问题要求你将这些原则应用于训练计划。对于超负荷，记住 FITT 原则：频率、强度、时间和类型。例如，为了对跑步者实施渐进超负荷，你可以增加距离（时间）或提高速度（强度）。
Mock exam application: 'A footballer wants to improve her speed. Design a weekly training schedule using the FITT principle.' You would specify: Frequency: 3 times a week; Intensity: sprint at 90% max effort; Time: 30 minutes; Type: interval sprints. This earns full marks.
模拟考试应用：'一名足球运动员想提高速度。使用 FITT 原则设计一个每周训练计划。' 你会明确：频率：每周3次；强度：90%最大努力冲刺；时间：30分钟；类型：间歇冲刺。这能获得满分。
5. The Skeletal System: Identifying Bones | 骨骼系统：识别骨骼
You must be able to label a skeleton diagram. Key bones for Year 7 WJEC include cranium, clavicle, scapula, humerus, radius, ulna, vertebrae, pelvis, femur, patella, tibia, and fibula. Often the diagram question awards marks for correct spelling. Practise by covering the names and testing yourself.
你必须能够标记骨骼图。Year 7 WJEC 的关键骨骼包括颅骨、锁骨、肩胛骨、肱骨、桡骨、尺骨、椎骨、骨盆、股骨、髌骨、胫骨和腓骨。图表题通常会因为拼写正确而得分。通过遮住名称自我测试来练习。
Mock question: 'Label bones A, B, and C on the diagram of the leg.' Typical answers: A: Femur
