2. Question 1: Synovial Joint Anatomy | 第 1 题：滑膜关节的解剖

Question: Describe the structure of a synovial joint and explain how each component facilitates movement. (4 marks)

题目：请描述滑膜关节的结构并解释各个组成部分如何促进运动。（4 分）

The model answer identifies five key structures: articular cartilage, synovial membrane, synovial fluid, joint capsule and ligaments. Articular cartilage covers bone ends to reduce friction and absorb shock. The synovial membrane secretes synovial fluid, which lubricates the joint and nourishes cartilage. The fibrous joint capsule encloses the joint, and ligaments reinforce it to prevent excessive movement.

示范答案指出五个关键结构：关节软骨、滑膜、滑液、关节囊和韧带。关节软骨覆盖在骨端以减小摩擦并吸收震动。滑膜分泌滑液，润滑关节并为软骨提供营养。纤维性关节囊包裹着整个关节，韧带则加强关节囊以防止过度的活动。

Many candidates lose marks by simply listing structures without linking each one to its functional role. To gain full marks, you must connect ‘articular cartilage’ directly to ‘reducing friction’ and ‘preventing wear’. Use precise anatomical language and avoid vague terms like ‘helps movement’.

很多考生只是列出了结构，却没有把每个结构与其功能联系起来，因而丢分。要获得满分，你必须把‘关节软骨’直接与‘减少摩擦’和‘防止磨损’联系起来。请使用精确的解剖术语，避免使用‘帮助运动’之类模糊的表述。

3. Question 2: Mechanics of Breathing at Rest | 第 2 题：安静时的呼吸机制

Question: Explain the process of inspiration at rest, referring to the muscles involved and pressure changes. (4 marks)

题目：请解释安静状态下吸气的过程，要求说明参与的肌肉和压力变化。（4 分）

Inspiration at rest is an active process driven by the diaphragm and external intercostal muscles. The diaphragm contracts and flattens, while the external intercostals lift the rib cage upwards and outwards. These actions increase the volume of the thoracic cavity, causing intrapulmonary pressure to drop below atmospheric pressure. Air then flows into the lungs until pressures equalise.

安静时的吸气是一个由膈肌和肋间外肌驱动的主动过程。膈肌收缩变平，肋间外肌将胸廓向上向外提拉。这些动作增大了胸腔容积，使肺内压下降到低于大气压，于是空气流入肺部直到压力平衡。

A common mistake is describing expiration instead of inspiration or ignoring pressure gradients. Remember that the examiner expects a clear sequence: muscle contraction → volume increase → pressure decrease → air entry. Naming the diaphragm alone is not enough; you must mention the external intercostals and the direction of pressure change.

一个常见的错误是描述了呼气而不是吸气，或者忽略了压力梯度。请记住，考官希望看到一个清晰的顺序：肌肉收缩 → 容积增加 → 压力下降 → 空气进入。只提到膈肌是不够的，你还必须提及肋间外肌以及压力变化的方向。

4. Question 3: Newton’s Three Laws of Motion | 第 3 题：牛顿三大运动定律

Question: Define Newton’s three laws of motion and provide a sporting example for each. (6 marks)

题目：请定义牛顿三大运动定律，并为每条定律各提供一个运动实例。（6 分）

The first law (inertia) states that a body remains at rest or in uniform motion unless acted upon by an external force. Example: a football stays still on the penalty spot until a player kicks it. The second law (acceleration) describes how the acceleration of an object is proportional to the net force and inversely proportional to its mass (F = ma). Example: a lighter sprinter accelerates faster than a heavier one for the same applied force. The third law (action-reaction) states that for every action there is an equal and opposite reaction. Example: a swimmer pushes water backwards, and the water pushes the swimmer forwards.

第一定律（惯性定律）指出，物体在没有外力作用时将保持静止或匀速直线运动状态。例如：足球在点球点上保持静止，直到有球员踢它。第二定律（加速度定律）描述了物体的加速度与所受合力成正比、与质量成反比（F = ma）。例如：在相同的作用力下，体重较轻的短跑运动员比较重的运动员加速更快。第三定律（作用力与反作用力定律）指出，每一个作用力都有一个大小相等、方向相反的反作用力。例如：游泳运动员向后推水，水则向前推游泳者。

To achieve all 6 marks, you must state both the law (1 mark) and a correct sporting application (1 mark) for each. Avoid generic examples such as ‘running’ without explaining which law applies. Using the formula F = ma demonstrates a deeper understanding for the second law.

要拿到全部 6 分，你必须为每条定律陈述定律（1 分）和正确的运动应用（1 分）。不要使用类似‘跑步’这样而不解释哪条定律的笼统例子。使用公式 F = ma 能展示你对第二定律更深入的理解。

5. Question 4: Skill Classification | 第 4 题：技能分类

Question: Place a volleyball serve on the following continua and justify each placement: muscular involvement, environmental influence, pacing, difficulty and organisation. (5 marks)

题目：将排球发球放在下列连续体上并为每个位置提供理由：肌肉参与度、环境影响、节奏控制、难度和组织性。（5 分）

Continuum	Placement	Justification
Muscular involvement	Gross	Large muscle groups are used in the whole-body movement.
Environmental influence	Open	The serve is affected by variables such as wind and opponent positioning.
Pacing	Externally paced	The timing is controlled by the referee’s whistle and the game situation.
Difficulty	Complex	It requires coordination, judgement and several sub-routines.
Organisation	Low	The movement can be broken down into discrete phases (toss, hit).

中文表格

连续体	位置	理由
肌肉参与度	粗大	全身运动中使用了大量肌肉群。
环境影响	开放	发球受风、对手站位等变量的影响。
节奏控制	外部控制	时机由裁判的哨声和比赛局势控制。
难度	复杂	它需要协调能力、判断力以及若干子程序。
组织性	低	动作可以拆分为明显的阶段（抛球、击球）。

A mark is given for each correct placement with a linked justification. Avoid contradictory answers, such as calling the serve ‘simple’ while also describing high perceptual demands. Practise classifying a range of sports skills to build confidence with the continua.

每个正确的位置及其对应的理由各得 1 分。要避免自相矛盾的答案，例如一边说发球‘简单’，一边又描述它具有很高的感知要求。请练习对一系列运动技能进行分类，从而熟练运用这些连续体。

6. Question 5: Principles of Training for a 400m Runner | 第 5 题：400 米跑者的训练原则

Question: Discuss the principles of training and apply them to a 400m runner. (8 marks)

题目：讨论训练原则并将其应用在一位 400 米跑者身上。（8 分）

A top-band answer uses the SPORT and FITT acronyms. SPORT covers: Specificity (training must match the demands of 400 m sprinting – energy systems, movement patterns), Progression (gradually increasing volume or intensity), Overload (working beyond the comfort zone), Reversibility (fitness losses when training stops) and Tedium (variety to maintain motivation). FITT details Frequency (4–5 sessions per week), Intensity (80–90 % of maximum heart rate), Time (45–60 minutes per session) and Type (interval training, plyometrics, speed endurance).

高分答案会用到 SPORT 和 FITT 这两个缩写词。SPORT 涵盖：专项性（训练必须匹配 400 米短跑的需求——能量系统、动作模式）、渐进性（逐步增加训练量或强度）、超负荷（超出舒适区进行运动）、可逆性（训练停止后体能水平下降）和乏味性（通过多样化来保持积极性）。FITT 则详细说明频率（每周 4–5 次）、强度（最大心率的 80–90 %）、时间（每次 45–60 分钟）和类型（间歇训练、增强式训练、速度耐力）。

Marks are heavily weighted towards application. Generic definitions of overload will not lift the response into the top band. You need to specify, for instance, that progression could involve reducing recovery intervals between 300 m repeats. Using quantified data (e.g., ‘increase intensity from 75 % to 85 % HRmax over six weeks’) shows precise planning and earns AO3 evaluation marks.

分数主要分配在应用层面。只给出超负荷的通用定义无法将答案提升到高分段。你需要具体说明，例如渐进性可以表现为缩短 300 米重复跑之间的恢复间歇。使用量化的数据（例如‘在六周内将强度从 75 % 最大心率提升至 85 %’）能展示出精确的规划，从而获得 AO3 评价类分数。

7. Question 6: Lever System at the Elbow | 第 6 题：肘关节的杠杆系统

Question: Analyse the lever system operating at the elbow during a bicep curl and state its mechanical advantage or disadvantage. (3 marks)

题目：分析在完成肱二头肌弯举时肘关节所运用的杠杆系统，并说明其机械利弊。（3 分）

The bicep curl operates as a third-class lever. The effort is applied by the biceps muscle on the radius, the fulcrum is the elbow joint, and the resistance is the weight in the hand plus the forearm. In a third-class lever the effort lies between the fulcrum and the resistance, giving the system a mechanical disadvantage: relatively large muscle force is required to move a smaller load, but it gains speed and range of motion.

肱二头肌弯举属于第三类杠杆。动力由肱二头肌施加在桡骨上，支点是肘关节，阻力则是手中的重量加上前臂。在第三类杠杆中，动力位于支点和阻力之间，这使得系统处于机械劣势：需要相对较大的肌肉力量来移动较小的负荷，但它可以换取更快的速度和更大的活动范围。

Drawing a simple labelled diagram, even with just arrows, helps secure full marks. Common errors include confusing the effort and resistance arms or labelling it as a first-class lever. Remember that most levers in the human body are third-class, designed for speed rather than force production.

画一个简单的带标注的示意图，哪怕只用箭头，就有助于拿满分。常见的错误包括混淆动力臂和阻力臂，或将其标注为第一类杠杆。请记住，人体中大多数杠杆是第三类的，它们的设计目标在于追求速度而非产生大力。

8. Mark Scheme and Command Word Insights | 第 8 题：评分方案与指令词解读

WJEC papers consistently use command words such as ‘describe’, ‘explain’, ‘analyse’ and ‘discuss’. ‘Describe’ requires factual recall without reasoning; ‘explain’ asks for a cause-and-effect sequence; ‘analyse’ demands breaking down a system into components; ‘discuss’ calls for balanced consideration of different viewpoints. Check how many marks are allocated: a 4-mark question typically requires at least four distinct teaching points.

WJEC 试卷一贯使用‘描述’、‘解释’、‘分析’和‘讨论’等指令词。‘描述’要求纯粹的事实回忆，不需要说理；‘解释’需要写出因果顺序；‘分析’要求将一个系统拆解为各个组成部分；‘讨论’则需要平衡地考量不同的观点。注意看分值：一道 4 分的题目通常至少需要四个不同的教学点。

Many students lose marks by misreading command words. Writing a descriptive paragraph where an ‘explain’ is required will cap your marks at AO1, missing AO2 and AO3. Underline the command word before you start writing and tick off each mark point as you include it.

很多学生因为误读指令词而丢分。如果题目要求‘解释’而你只写了一段描述性的文字，那么你的得分将被限制在 AO1，而无法获得 AO2 和 AO3 的分数。开始答题前请先在指令词下划线，并在书写过程中逐项勾掉已经包含的得分点。

9. Common Pitfalls and How to Avoid Them | 第 9 节：常见失分陷阱及对策

Pitfall 1: vague language. Instead of ‘the blood gets pumped faster’, write ‘cardiac output increases due to elevated stroke volume and heart rate’. Pitfall 2: ignoring units. When discussing oxygen consumption, state ‘ml kg⁻¹ min⁻¹’ or you risk losing a mark. Pitfall 3: missing evaluation. For an 8-mark discuss question, around 2–3 marks are reserved for weighing pros and cons, limitations or contextual decisions. For example, ‘While plyometrics improve power, they increase injury risk if recovery is inadequate’.

陷阱 1：语言模糊。不要写‘血液泵得更快’，而要写‘由于每搏输出量和心率的提高，心输出量增加’。陷阱 2：忽略单位。在讨论耗氧量时，要写明‘ml kg⁻¹ min⁻¹’，否则可能丢分。陷阱 3：缺乏评价。对于 8 分的讨论题，大约有 2–3 分是留给权衡利弊、局限或情境判断的。例如，‘增强式训练虽然能提升爆发力，但如果恢复不足会加大受伤风险’。

Another repeat offender is poor time management. The 40-minute window for 30 marks means roughly 1.3 minutes per mark. Plan your time: spend around 14 minutes on the two long-answer questions and the rest on smaller ones. Always leave two minutes to re-read and add any missing key terms.

另一个屡犯的错误是时间管理不善。30 分的题目分配 40 分钟，意味着每 1 分约 1.3 分钟。要规划好时间：用大约 14 分钟作答两道长题目，剩下的给小题目。务必留出两分钟时间重新读一遍，补充可能漏掉的关键术语。

10. Revision Roadmap and Final Tips | 第 10 节：复习路线图与终极建议

Construct a revision grid linking each topic to its relevant AO. For anatomy topics such as synovial joints and the respiratory system, drill diagrams until you can label them from memory. For biomechanics (levers, Newton’s laws), practise applying abstract principles to concrete sports scenarios. Use flashcards with one side showing a command word and a sport, the other side a structured plan. Finally, complete at least two timed past papers under exam conditions to build speed and stamina.

制作一张复习表格，将每个主题与其对应的 AO 联系起来。对于滑膜关节和呼吸系统等解剖学主题，要反复练习绘图，直到你能从记忆中标注出来。对于生物力学部分（杠杆、牛顿定律），要多练习将抽象原理应用到具体的运动场景中去。使用闪卡，一面写着指令词和一项运动，另一面写着结构化的作答计划。最后，在考试条件下至少完成两套限时真题，以锻炼速度与耐力。

This mock paper shows that WJEC rewards precision, application and a logical chain of reasoning. Use the model answers as a benchmark and practise self-assessment against the mark schemes. By internalising the examiner’s expectations, you will walk into the unit test with confidence and a clear strategy for every question.

这份模拟卷表明，WJEC 青睐的是精确、应用和清晰的逻辑链。请用示范答案作为基准，对照评分方案进行自我评估。一旦内化了考官的期望，你将满怀信心地步入考场，并对每道题都有清晰的应对策略。
