1. Multiple Choice: Identifying Bones of the Arm | 选择题：识别手臂骨骼
Question: Which bone forms the upper arm? A) Femur, B) Tibia, C) Humerus, D) Radius. The correct choice is C, the humerus. The humerus is a long bone that connects the shoulder to the elbow and enables a wide range of arm movements. Option A, the femur, is the thigh bone; B, the tibia, is a shin bone; and D, the radius, is located on the thumb side of the forearm.
题目：哪块骨骼构成上臂？A) 股骨，B) 胫骨，C) 肱骨，D) 桡骨。正确选择是C，肱骨。肱骨是连接肩部与肘部的长骨，使手臂能够进行大幅度的动作。选项A的股骨是大腿骨；B的胫骨是小腿骨；D的桡骨位于前臂拇指侧。
Many students confuse the humerus with the radius because both are in the arm. Remember, the humerus is the single bone in the upper arm, whereas the radius is one of the two bones in the forearm. Labeling a skeleton diagram before the test helps reinforce these names.
许多学生容易混淆肱骨和桡骨，因为它们都在手臂上。记住，肱骨是上臂的单块骨头，而桡骨是前臂两根骨头之一。考前在骨架图上标注名称有助于巩固这些术语。
Humerus → Upper Arm | Radius → Forearm (thumb side) | Ulna → Forearm (little finger side)
肱骨 → 上臂 | 桡骨 → 前臂（拇指侧） | 尺骨 → 前臂（小指侧）
2. Multiple Choice: Health-Related Fitness Components | 选择题：健康相关体能成分
Question: A cross-country runner needs to sustain a steady pace over 5 km. Which health-related fitness component is most critical? A) Muscular strength, B) Cardiovascular endurance, C) Flexibility, D) Body composition. The answer is B, cardiovascular endurance. This component reflects the ability of the heart, lungs, and blood vessels to supply oxygen to working muscles during prolonged activity.
题目：一位越野跑者需要维持在5公里内的稳定配速。哪项健康相关体能成分最为关键？A) 肌肉力量，B) 心血管耐力，C) 柔韧性，D) 身体成分。答案是B，心血管耐力。该成分反映了心脏、肺和血管在持续活动中向工作的肌肉供氧的能力。
Muscular strength (A) is the maximum force a muscle can exert, useful in weightlifting but less vital here. Flexibility (C) is the range of movement at a joint, and body composition (D) refers to the ratio of fat to lean mass. While all components contribute to overall fitness, the aerobic nature of distance running makes cardiovascular endurance the priority.
肌肉力量（A）是肌肉能产生的最大力，在举重中有用但在此不是关键。柔韧性（C）是关节的活动范围，身体成分（D）指脂肪与瘦体重的比例。虽然所有成分都对健康有贡献，但长跑的有氧特性使心血管耐力成为优先项。
3. Multiple Choice: Applying the FITT Principle | 选择题：应用FITT原则
Question: In the FITT principle, ‘Intensity’ refers to: A) How often you exercise, B) How hard you exercise, C) How long each session lasts, D) The specific activity chosen. The correct answer is B. Intensity measures the level of effort, often monitored through heart rate, breathing rate, or perceived exertion.
题目：在FITT原则中，”强度”指的是：A) 运动频率，B) 运动多么剧烈，C) 每次训练的时长，D) 选择的具体活动。正确答案是B。强度衡量努力的程度，通常通过心率、呼吸频率或主观疲劳感来监控。
To avoid confusion, remember the FITT acronym: Frequency (how often), Intensity (how hard), Time (how long), and Type (what kind). An effective training plan always specifies all four components. For cardiorespiratory fitness, intensity is often set between 60% and 85% of maximum heart rate.
为避免混淆，请记住FITT首字母缩写：频率(多久一次)，强度(多剧烈)，时间(多长时间)，类型(哪种运动)。一个有效的训练计划总会明确这四个要素。对于心肺适能，强度通常设定在最大心率的60%到85%之间。
FITT: Frequency · Intensity · Time · Type
FITT：频率 · 强度 · 时间 · 类型
4. Short Answer: Benefits of a Warm-Up | 简答题：热身的好处
Task: Describe three physiological benefits of a complete warm-up before exercise. (3 marks)
任务：描述运动前完整热身的三项生理益处。（3分）
One mark is awarded for stating that a warm-up gradually increases heart rate and blood flow to the muscles. This delivers more oxygen and nutrients, preparing the muscles for intense work and reducing the risk of tears or strains. Another benefit is that it raises muscle temperature, which improves elasticity and speeds up contraction and relaxation cycles. The third point is that it enhances joint mobility by stimulating the release of synovial fluid, allowing a greater range of motion and lowering injury risk.
一个得分点是说明热身能逐渐提高心率，增加肌肉的血流量。这输送了更多氧气和营养，使肌肉为高强度工作做好准备，降低撕裂或拉伤的风险。另一个益处是提高肌肉温度，增强弹性，加快收缩与放松循环。第三点是热身通过刺激滑液分泌增强关节灵活性，提供更大的活动范围并降低受伤风险。
Many students forget the psychological aspect: a warm-up also improves mental focus and concentration. In an exam, you can also mention that it rehearses movement patterns for the upcoming activity. Always link your points back to improved performance and injury prevention.
许多学生忘记心理方面的益处：热身还能提高精神专注力和注意力。在考试中，你还可以提到它提前演练了即将进行的动作模式。始终把你的答案联系到提升运动表现和预防损伤上。
5. Short Answer: Open and Closed Skills | 简答题：开放式与封闭式技能
Question: Is a basketball free throw an open or closed skill? Justify your choice. (2 marks)
题目：篮球罚球是开放式还是封闭式技能？请说明理由。（2分）
A free throw is a closed skill. Closed skills are performed in a stable, predictable environment where the performer controls the timing and the execution is self-paced. During a free throw, there is no defensive pressure, the distance is fixed, and the player follows a consistent routine. In contrast, an open skill, such as dribbling past a defender, is affected by a changing environment and requires continuous adaptation.
罚球是一项封闭式技能。封闭式技能在稳定、可预测的环境中进行，执行者控制时机，动作由自己按节奏完成。罚球时，没有防守压力，距离固定，球员遵循一套固定的动作程序。相比之下，开放式技能，如运球过防守者，受变化的环境影响，需要不断调整。
To secure full marks, explicitly state “closed skill” and then explain that the environment is constant and the movement is self-paced. Avoid simply saying “because there is no defender” without linking to the definition of a closed skill. Use keywords like ‘predictable’, ‘self-paced’, and ‘habitual’.
为拿到满分，要明确写出”封闭式技能”，然后解释环境是恒定的、动作是自定节奏的。不要仅仅说”因为没有防守者”而不联系封闭式技能的定义。使用”可预测”、”自定节奏”、”习惯性”等关键词。
6. Data Response: Heart Rate and Exercise Intensity | 数据分析题：心率与运动强度
Data: A Year 7 student, aged 12, measured heart rate during three activities. The results are shown below. Use the data to determine the intensity zone for each activity.
数据：一名12岁的Year 7学生在三项活动中测量了心率。结果如下表所示。利用数据判断每项活动所处的强度区间。
| Activity | Heart Rate (bpm) |
|---|---|
| Walking | 112 |
| Jogging | 146 |
| Sprinting | 182 |
First, estimate maximum heart rate (HRmax) using the formula: HRmax = 220 − age. For a 12‑year‑old, HRmax = 220 − 12 = 208 bpm. Next, calculate the percentage of HRmax for each activity. Walking: (112 ÷ 208) × 100 ≈ 54%, which falls in the light‑intensity zone (50–60% HRmax). Jogging: (146 ÷ 208) × 100 ≈ 70%, moderate intensity (60–80% HRmax). Sprinting: (182 ÷ 208) × 100 ≈ 87.5%, vigorous intensity (80–90% HRmax). Thus, walking is light, jogging is moderate, and sprinting is vigorous.
首先，使用公式估算最大心率(HRmax): HRmax = 220 − 年龄。12岁学生的HRmax = 220 − 12 = 208 bpm。接下来，计算每项活动最大心率的百分比。步行: (112 ÷ 208) × 100 ≈ 54%，属于低强度区间（50–60% HRmax）。慢跑: (146 ÷ 208) × 100 ≈ 70%，中等强度（60–80% HRmax）。冲刺: (182 ÷ 208) × 100 ≈ 87.5%，高强度（80–90% HRmax）。因此，步行为低强度，慢跑为中等，冲刺为高强度。
When answering similar data questions, always show your working. Write the formula, substitute the values, calculate the percentage, and then name the intensity zone. The context of the sport helps confirm your interpretation; for example, sprinting should never be classified as light intensity.
回答类似的数据分析题时，务必展示出计算过程。写出公式，代入数值，计算百分比，然后说出强度区间。运动的情境有助于确认你的解读；例如，冲刺绝不应被归类为低强度。
Target HR Zone (Moderate) = (220 − age) × 0.60 to 0.80
目标心率区间（中等）= (220 − 年龄) × 0.60 至 0.80
7. Extended Writing: Designing a Fitness Circuit | 扩展写作：设计一个健身循环
Task: Design a circuit training session to improve cardiovascular endurance for a Year 7 student. Outline the FITT components and give three example stations. (6 marks)
任务：为改善一名Year 7学生的心血管耐力设计一个循环训练。列出FITT要素并给出三个示例站点。（6分）
A strong answer specifies each FITT component clearly. Frequency: 3 times per week, allowing rest days between sessions. Intensity: 60–75% of maximum heart rate, monitored by taking the pulse at the wrist or using a heart rate monitor. Time: each station lasts 45 seconds with 15 seconds of rest, repeated for 3 full circuits, giving a total workout time of about 20–25 minutes. Type: bodyweight exercises that keep the heart rate elevated, such as shuttle runs, step-ups, and skipping ropes.
一个高分的答案会清晰地说明每个FITT要素。频率：每周3次，期间安排休息天数。强度：最大心率的60–75%，可通过手腕脉搏或心率监测器监控。时间：每个站点持续45秒，休息15秒，重复3个完整循环，总训练时间约20–25分钟。类型：保持心率较高的自重练习，如折返跑、台阶上下和跳绳。
For the three stations, you could propose: Station 1 – shuttle runs over 10 metres, which involve rapid changes of direction and elevate heart rate; Station 2 – bodyweight squats with an explosive jump, working large muscle groups; Station 3 – skipping with a rope, a rhythmic, low‑impact exercise that maintains cardiovascular output. Always justify why exercises were chosen, linking them to endurance and enjoyment for Year 7 pupils.
对于三个站点，可以提出：站点1——10米折返跑，涉及快速变向并提升心率；站点2——带爆发性跳跃的自重深蹲，锻炼大肌群；站点3——跳绳，一种有节奏、低冲击的运动，能维持心血管输出。总要解释为什么选择这些练习，将它们与耐力和Year 7学生的乐趣结合起来。
To reach top marks, explain how the circuit can be progressed. For instance, gradually increase the work interval to 60 seconds or add a fourth station. Mention that recording heart rate before, during, and after the session helps check if the intensity is correct.
要获得最高分，请说明如何对循环进行进阶。例如，逐渐将工作间隔增加到60秒，或增加第四个站点。提及在训练前后和过程中记录心率有助于检查强度是否恰当。
8. Extended Writing: Promoting an Active Lifestyle | 扩展写作：推广积极生活方式
Scenario: Your friend rarely exercises. Suggest two practical strategies to help them become more active and explain how each benefits their health. (4 marks)
情境：你的朋友很少锻炼。提出两个实用的策略帮助他们变得更活跃，并解释每种策略对健康的好处。（4分）
Strategy 1: Encourage active travel, such as walking or cycling to school. This builds regular, moderate‑intensity physical activity into their daily routine without requiring extra time. Health benefit: it strengthens the heart muscle, improves cardiovascular endurance, and helps maintain a healthy body weight by burning calories consistently.
策略1：鼓励积极出行，如步行或骑自行车上学。这将规律的中等强度身体活动融入日常生活，无需额外时间。健康益处：增强心肌，改善心血管耐力，并通过持续消耗热量帮助维持健康体重。
Strategy 2: Invite them to join a lunchtime or after‑school sports club. Social support makes exercise enjoyable and increases adherence. Health benefit: participating in team sports develops muscular strength and coordination, while also releasing endorphins that improve mood and reduce stress.
策略2：邀请他们加入午间或课后运动俱乐部。社会支持使锻炼变得有趣并提高坚持性。健康益处：参与团队运动会发展肌肉力量和协调性，同时释放内啡肽，改善情绪和减轻压力。
Other acceptable answers include setting small, achievable goals (e.g., 10‑minute brisk walk during break) or using a physical activity diary. The key is to link each suggestion to a clear physical, social, or mental health gain, demonstrating understanding of a balanced, healthy lifestyle.
其他可接受的答案包括设定小而可达成的目标（例如，休息时10分钟快走）或使用身体活动日记。关键在于将每个建议与明确的身体、社交或心理健康收益联系起来，展示你对均衡健康生活方式的理解。
