📚 IGCSE CAIE Physical Education: Unit Mock Test Walkthrough | IGCSE CAIE 体育：单元测试模拟卷解析

This walkthrough breaks down a typical IGCSE CAIE Physical Education unit mock test, covering the command words, mark schemes and common pitfalls. Use the paired explanations to check your understanding before the real exam.

本文拆解一份典型的 IGCSE CAIE 体育单元测试模拟卷，涵盖指令词、评分标准和常见失分点。请结合中英对照解析，在正式考试前检验自己的掌握程度。

1. Mock Test Structure and Command Words | 模拟卷结构与指令词

This mock unit test contains Section A with five multiple-choice questions (MCQs) and Section B with five short-answer questions. It is marked out of 25. The same command words appear in the real CAIE IGCSE Physical Education Paper 1, so you must read them carefully.

本模拟单元测试包括 A 部分 5 道选择题和 B 部分 5 道简答题，总分 25 分。正式 CAIE IGCSE 体育 Paper 1 也会使用相同的指令词，因此必须仔细审题。

In short-answer questions, ‘state’ asks for a one-word or brief answer, ‘describe’ asks what happens, ‘explain’ requires a reason or link, and ‘compare’ asks for similarities and differences. Always match your answer length to the number of marks.

在简答题中，’state’ 要求单词或简短回答，’describe’ 要求说出发生了什么，’explain’ 要求给出原因或联系，’compare’ 要求比较异同。答案长度必须与分值匹配。

• State = give a fact
• State = 给出事实
• Describe = say what is seen or what happens
• Describe = 描述所见或所发生的事
• Explain = give a reason or effect
• Explain = 给出原因或影响
• Compare = show similarities and differences
• Compare = 说明相同点和不同点

2. MCQs 1-2: Skeletal System Basics | 选择题 1-2：骨骼系统基础

Question 1: Which bone protects the brain and forms the top of the skull? A Scapula B Sternum C Cranium D Pelvis. The correct answer is C, cranium. It is a flat bone that surrounds the brain.

第1题：哪块骨保护大脑并构成颅骨顶部？A 肩胛骨 B 胸骨 C 颅骨 D 骨盆。正确答案是 C 颅骨。它是包围大脑的扁骨。

Question 2: The shoulder joint is an example of which type of synovial joint? A Hinge B Ball-and-socket C Pivot D Gliding. The answer is B, ball-and-socket. This allows movement in three planes: flexion, extension, abduction, adduction, rotation.

第2题：肩关节属于哪种滑膜关节？A 铰链关节 B 球窝关节 C 枢轴关节 D 滑动关节。答案是 B 球窝关节。它允许在三个平面运动：屈、伸、外展、内收、旋转。

Examiners often link bones to their protection or movement function. In a ‘describe’ question, naming the bone is not enough; you must say what it does.

考官常把骨骼与其保护或运动功能联系起来。在“describe”题中，只说出骨名不够，还需说明它的作用。

3. MCQs 3-4: Muscular Contractions and Roles | 选择题 3-4：肌肉收缩与角色

Question 3: During elbow flexion, which muscle is the antagonist? A Biceps brachii B Triceps brachii C Deltoid D Latissimus dorsi. The answer is B, triceps brachii. The biceps brachii is the agonist, while the triceps relaxes to allow movement.

第3题：肘关节屈曲时，哪块肌肉是对抗肌？A 肱二头肌 B 肱三头肌 C 三角肌 D 背阔肌。答案是 B 肱三头肌。肱二头肌是主动肌，而肱三头肌放松以允许运动。

Question 4: A gymnast holds a handstand without moving. Which type of muscle contraction occurs? A Isotonic concentric B Isotonic eccentric C Isometric D Isokinetic. The answer is C. In an isometric contraction, the muscle generates force but its length stays the same.

第4题：体操运动员保持倒立不动，发生哪种肌肉收缩？A 等张向心收缩 B 等张离心收缩 C 等长收缩 D 等动收缩。答案 C。在等长收缩中，肌肉产生力但长度不变。

Common confusion occurs between agonist and antagonist. The agonist is the muscle that contracts to create movement; the antagonist relaxes and opposes the movement.

常见混淆在于主动肌和对抗肌。主动肌是收缩产生动作的肌肉；对抗肌放松并阻止反向动作。

4. MCQ 5: Energy System for Sprint
