1. Musculoskeletal System Key Terms | 肌肉骨骼系统核心术语
The musculoskeletal system is your body’s engine room. For OCR, you must confidently label bones and muscles, and describe how they work together to create movement at synovial joints. Think of bones as levers, joints as fulcrums and muscles as the force generators pulling on those levers via tendons.
肌肉骨骼系统是你身体的引擎室。在 OCR 考纲中，你必须能自信地标注骨骼和肌肉，并描述它们如何在滑膜关节处协同工作产生动作。可以把骨骼想象成杠杆，关节是支点，肌肉是通过肌腱拉动杠杆的力量发生器。
- Flexion — Decreasing the angle at a joint, e.g., bending the elbow during a bicep curl.
屈曲 — 减小关节角度，例如进行肱二头肌弯举时弯曲肘部。 - Extension — Increasing the angle at a joint, e.g., straightening the knee in a football kick.
伸展 — 增加关节角度，例如足球踢球时伸直膝关节。 - Abduction — Moving a limb away from the midline of the body, e.g., lifting arms sideways in a star jump.
外展 — 将肢体远离身体中线，例如星形跳中向侧面抬起手臂。 - Adduction — Moving a limb toward the midline, e.g., bringing arms back down in a star jump.
内收 — 将肢体移向身体中线，例如星形跳中将手臂收回体侧。 - Rotation — Turning a limb around its long axis, e.g., turning the head to watch a ball in hockey.
旋转 — 围绕肢体长轴转动，例如曲棍球中转头看球。 - Antagonistic pair — Two muscles working together where one contracts (agonist) while the other relaxes (antagonist), e.g., biceps and triceps at the elbow.
拮抗肌对 — 两组协同工作的肌肉，一方收缩（主动肌）而另一方放松（拮抗肌），例如肘关节处的肱二头肌和肱三头肌。
A quick memory trick for abduction vs. adduction: ‘Abduction starts with AB — think of taking a limb AWAY from the Body.’ Adduction then is the reverse, returning the limb back toward the centre.
外展和内收的快速记忆技巧：”外展的英文 Abduction 以 AB 开头——想象把肢体从身体中央带走 Away from Body。” 内收则是相反动作，把肢体带回中心。
2. Cardiovascular and Respiratory Terminology | 心血管与呼吸系统术语
OCR exam papers love to ask how the heart and lungs respond to exercise and why those responses improve performance. You need to memorise the pathway of blood through the double circulatory system and the mechanics of breathing at rest versus during exercise.
OCR 试卷喜欢考查心脏和肺部如何对运动做出反应，以及为什么这些反应能提升运动表现。你需要牢记血液穿过双循环系统的路径，以及安静时和运动时呼吸机制的差异。
- Stroke volume — The volume of blood pumped out of the left ventricle per beat. It increases with training as the heart muscle becomes stronger.
每搏输出量 — 左心室每次搏动泵出的血量。随着训练加强心肌，每搏输出量会增加。 - Cardiac output — The total volume of blood pumped by the heart per minute (stroke volume × heart rate).
心输出量 — 心脏每分钟泵出的血液总量（每搏输出量 × 心率）。 - Vasodilation — The widening of blood vessels to increase blood flow to working muscles during exercise.
血管舒张 — 运动期间血管扩张以增加流向工作肌肉的血量。 - Vasoconstriction — The narrowing of blood vessels to reduce blood flow to non-essential organs during exercise.
血管收缩 — 运动期间血管收缩以减少流向非必要器官的血量。 - Tidal volume — The amount of air inhaled and exhaled in a normal breath at rest. It increases sharply during exercise.
潮气量 — 安静时一次正常呼吸吸入和呼出的空气量。运动期间潮气量急剧上升。 - Minute ventilation — The volume of air inhaled and exhaled per minute (tidal volume × breathing rate).
每分通气量 — 每分钟吸入和呼出的空气总量（潮气量 × 呼吸频率）。
The cardiac output equation appears frequently in multiple-choice and short-answer questions:
心输出量公式经常出现在选择题和简答题中：
Cardiac Output (Q) = Stroke Volume (SV) × Heart Rate (HR)
Remember this simple analogy: think of a tap filling a bucket. Stroke volume is how much water spurts out each time you open the tap, heart rate is how often you turn the tap on, and cardiac output is how much water ends up in the bucket per minute.
记住这个简单的类比：想象一个水龙头往桶里注水。每搏输出量是每次打开水龙头喷出的水量，心率是你开关水龙头的频率，心输出量就是每分钟桶里最终有多少水。
3. Aerobic and Anaerobic Energy Vocab | 有氧与无氧能量词汇
Understanding energy system terminology lets you explain why a 100 m sprinter breathes heavily after the race, while a marathon runner maintains a steady breathing rhythm throughout. OCR expects you to link the duration and intensity of activity to which energy system predominates.
理解能量系统术语能让你解释为什么 100 米短跑选手赛后大口喘气，而马拉松选手全程保持稳定呼吸节奏。OCR 期望你将活动时长和强度与主导供能系统联系起来。
- Aerobic exercise — Activity performed with sufficient oxygen to meet energy demands, e.g., jogging, cycling long distances. It uses glucose and fatty acids to produce CO₂ and water.
有氧运动 — 在有足够氧气满足能量需求的情况下进行的活动，例如慢跑、长距离骑行。它利用葡萄糖和脂肪酸产生二氧化碳和水。 - Anaerobic exercise — High-intensity activity where oxygen supply cannot match demand, e.g., sprinting, weightlifting. It produces lactic acid as a by-product.
无氧运动 — 供氧无法满足需求的高强度活动，例如短跑、举重。它产生乳酸作为副产品。 - Lactic acid — A substance produced during anaerobic respiration that causes muscle fatigue and the burning sensation during intense activity.
乳酸 — 无氧呼吸过程中产生的一种物质，会导致肌肉疲劳和剧烈运动时的灼烧感。 - EPOC (Excess Post-exercise Oxygen Consumption) — The extra oxygen consumed after exercise to clear lactic acid, replenish glycogen and restore the body to resting state. Often called ‘oxygen debt’.
运动后过量氧耗 — 运动后额外消耗以清除乳酸、补充糖原并使身体恢复安静状态的氧气量。常被称为”氧债”。
Mnemonic to recall the order of energy pathway use: ‘ATP-PC for the flash, Anaerobic for the dash, Aerobic for the long haul.’ It captures the time frame — immediate, short-term and long-term energy provision.
记忆供能途径使用顺序的口诀：”ATP-PC 供爆发，无氧做功冲短坡，有氧耐力扛长活。” 这概括了即时、短期和长期供能的时间框架。
4. Movement Analysis and Planes & Axes | 动作分析与平面、轴
Movement analysis questions ask you to identify the plane, axis and lever system operating during a specific sporting action. These terms sound abstract, but you can anchor them to a giant imaginary sheet of glass slicing through your body.
动作分析题要求你识别特定运动动作中起作用的平面、轴和杠杆系统。这些术语听起来抽象，但你可以把它们固定在贯穿身体的一张巨大虚拟玻璃板上。
- Sagittal plane — Divides the body into left and right halves. Movements like running, squatting and bicep curls happen in this plane.
矢状面 — 将身体分为左右两半。跑步、深蹲和肱二头肌弯举等动作发生在这个平面。 - Frontal plane — Divides the body into front and back. Movements like star jumps (abduction/adduction) and cartwheels occur here.
额状面 — 将身体分为前后两部分。星形跳（外展/内收）和侧手翻等动作发生在这里。 - Transverse plane — Divides the body into top and bottom. Rotation movements like a discus thrower’s spin or a golf swing operate in this plane.
水平面 — 将身体分为上下两部分。铁饼选手的旋转或高尔夫挥杆等旋转动作发生在这个平面。 - Transverse axis — Runs from side to side; paired with the sagittal plane, enabling forward rolls and somersaults.
额状轴 — 从一侧到另一侧，与矢状面配对，实现前滚翻和空翻。 - Sagittal axis — Runs from front to back; paired with the frontal plane, enabling cartwheels.
矢状轴 — 从前面到后面，与额状面配对，实现侧手翻。 - Longitudinal axis — Runs from top to bottom; paired with the transverse plane, enabling a full twist in trampolining.
垂直轴 — 从头顶到脚底，与水平面配对，实现蹦床中的全身转体。
Link the plane to its axis using this rule: the axis runs perpendicular — it pokes straight through the plane like a skewer through a sheet of paper. The sagittal plane pairs with the transverse axis, frontal plane with sagittal axis, transverse plane with longitudinal axis.
用这个规则连接平面和轴：轴垂直于平面，就像一根竹签戳穿一张纸。矢状面与额状轴配对，额状面与矢状轴配对，水平面与垂直轴配对。
5. Lever Systems and Mechanical Advantage | 杠杆系统与机械效益
OCR exams regularly feature diagrams of lever systems where you must identify the effort, fulcrum and load. A lever’s class determines whether it provides speed and range of motion or a mechanical advantage for force generation.
OCR 考试经常出现杠杆系统图示，你必须指出动力点、支点和阻力点。杠杆的类别决定了它是提供速度和运动幅度，还是为产生力提供机械效益。
- First-class lever — Fulcrum sits between effort and load, e.g., the neck extending at the atlanto-occipital joint while heading a football. Think ‘F in the middle’ — Fulcrum.
第一类杠杆 — 支点在动力点和阻力点之间，例如足球头球时寰枕关节处的颈部伸展。记住”中间是 F”——支点 Fulcrum 在中间。 - Second-class lever — Load sits between fulcrum and effort, e.g., standing on tiptoes at the ankle. This class always produces a mechanical advantage — load arm is shorter than effort arm.
第二类杠杆 — 阻力点在支点和动力点之间，例如足尖站立时的踝关节。此类杠杆总能产生机械效益——阻力臂短于动力臂。 - Third-class lever — Effort sits between fulcrum and load, e.g., a bicep curl at the elbow. This is the most common lever in the body; it sacrifices force for speed and range of motion.
第三类杠杆 — 动力点在支点和阻力点之间，例如肘关节处的肱二头肌弯举。这是身体中最常见的杠杆；它为速度和运动幅度牺牲了力。 - Mechanical advantage — When the effort arm is longer than the load arm, a lever can move a heavy load with less effort. Second-class levers excel at this.
机械效益 — 当动力臂长于阻力臂时，杠杆能用较小的力移动较大的负荷。第二类杠杆擅长这一点。
To quickly classify any lever: identify which component sits between the other two. Use the mnemonic ‘1-2-3, F-L-E’ (First class Fulcrum middle, Second class Load middle, Third class Effort middle). This forensic approach guarantees a correct answer even on the trickiest diagram questions.
快速归类任何杠杆的方法：找出哪个部件位于另外两个之间。使用口诀”一二三，支阻动”（第一类支点中间，第二类阻力中间，第三类动力中间）。这种缜密方法能确保即使在最复杂的图示题中也能选对答案。
6. Components of Fitness Definitions | 体适能要素定义
Fitness components are split into health-related and skill-related categories. OCR often asks you to name a fitness test for each component and link the component to a specific sport. Precision in definitions is crucial — never confuse ‘balance’ with ‘coordination’ or ‘muscular endurance’ with ‘muscular strength’.
体适能要素分为健康相关类和技能相关类。OCR 经常要求你为每个要素命名一项体适能测试，并将该要素与具体运动联系起来。定义的精确性至关重要——切勿将”平衡”与”协调”混淆，或将”肌肉耐力”与”肌肉力量”混淆。
| Component 要素 |
Definition 定义 |
Sport Example 运动案例 |
|---|---|---|
| Cardiovascular endurance 心血管耐力 |
The ability of the heart and lungs to supply oxygen to working muscles over a sustained period. 心、肺长时间为工作肌肉供氧的能力。 |
Marathon running 马拉松长跑 |
| Muscular strength 肌肉力量 |
The maximum amount of force a muscle or muscle group can exert in a single contraction. 单次收缩中一块肌肉或肌群能产生的最大力量。 |
Rugby scrum pushing 橄榄球并列争球推进 |
| Agility 敏捷性 |
The ability to change direction quickly while maintaining body control. 在保持身体控制的同时快速变向的能力。 |
Netball dodging 无挡板篮球的闪避动作 |
| Reaction time 反应时 |
The time it takes to respond to a stimulus and initiate movement. 从接收到刺激到启动动作所用的时间。 |
100 m sprint start gun 100 米短跑发令枪 |
Create flashcards with ‘definition on one side, sport example on the other’ to drill these terms. When writing your answer in the exam, always name the component clearly first, then give the definition in your own words before adding your sport-specific application to secure AO2 marks.
制作抽认卡，一面写定义，另一面写运动案例，反复练习这些术语。在考试作答时，始终先清晰写出要素名称，然后用自己的话给出定义，最后补充特定运动的应用以获得 AO2 分数。
7. Principles and Methods of Training | 训练原则与方法
Training principles are the scientific rules that ensure fitness improvements happen safely and efficiently. If you ignore them, you get injury or plateau. OCR wants you to apply the SPORT and FITT principles to specific training programmes and justify why one method suits a particular athlete more than another.
训练原则是确保体适能安全有效提升的科学法则。忽视它们会导致受伤或平台期。OCR 希望你将 SPORT 和 FITT 原则应用到具体训练计划中，并论证为什么某种方法比另一种更适合某位运动员。
- Specificity — Training must match the demands of the sport, e.g., a swimmer should train in the water focusing on stroke technique, not just running on land.
专项性 — 训练必须与运动项目的要求匹配，例如游泳选手应在水中专注于划水技术训练，而非仅在陆地上跑步。 - Progressive overload — Gradually increasing the stress placed on the body to continue making gains. If the workload stays the same, adaptation stalls.
渐进超负荷 — 逐步增加施加于身体的压力以持续获得进步。如果负荷不变，适应就会停滞。 - Reversibility — The loss of fitness gains when training stops or intensity sharply drops — ‘use it or lose it’.
可逆性 — 当训练停止或强度骤降时体适能增益的流失——”不用则废”。 - Tedium — Boredom from repetitive training; coaches must vary sessions to maintain motivation and performance quality.
枯燥性 — 重复训练带来的厌倦；教练必须变换训练课以保持积极性和训练质量。 - FITT principle — Frequency, Intensity, Time, Type — the four levers you adjust when designing an overloaded training programme.
FITT 原则 — 频率、强度、时长、类型——设计超负荷训练计划时可以调节的四个杠杆。
Use the mnemonic ‘Special People Run Triathlons’ for SPOR(T): Specificity, Progressive overload, Over-reversibility (just remember ‘Reversibility’), Tedium. FITT is self-contained: ‘How often? How hard? How long? What kind?’ Answer these four questions for any training scenario and you will hit the marking criteria.
用口诀”特进可枯”来记 SPOR(T)：专项性、渐进超负荷、可逆性、枯燥性。FITT 自成体系：”频率多高？强度多大？时长多久？类型怎样？” 对任何训练情境回答这四个问题，就能命中采分点。
8. Skill Acquisition and Classification | 技能习得与分类
Skill classification on the OCR syllabus places skills on continua: open to closed, self-paced to externally-paced, gross to fine, and simple to complex. No skill is purely one type; you must judge where it sits between the two extremes on each continuum.
OCR 考纲中的技能分类将技能置于不同连续体上：开放式到封闭式、自定节奏到外部节奏、粗放到精细、简单到复杂。没有哪种技能是纯粹一种类型的；你必须判断它在每个连续体两端之间的位置。
- Open skill — Performed in an unpredictable, changing environment where you must react to others, e.g., a hockey pass in a crowded midfield.
开放式技能 — 在不可预测、不断变化的环境中完成，需要对他人的举动做出反应，例如中场拥挤时的曲棍球传球。 - Closed skill — Performed in a stable, predictable setting with minimal external interference, e.g., a gymnastics floor routine.
封闭式技能 — 在稳定、可预测的环境中完成，外部干扰极小，例如自由体操成套动作。 - Self-paced skill — The performer controls the timing and speed of execution, e.g., a free throw in basketball.
自定节奏技能 — 执行者控制动作的时机和速度，例如篮球罚球。 - Externally-paced skill — An external factor dictates the timing, e.g., starting a sprint race when the gun fires.
外部节奏技能 — 外部因素决定时机，例如发令枪响时开始短跑。 - Gross skill — Involves large muscle groups and big movements, e.g., a rugby tackle.
粗放技能 — 涉及大肌肉群和大范围动作，例如橄榄球擒抱。 - Fine skill — Requires precision and small muscle groups, e.g., a snooker shot.
精细技能 — 需要精准和小肌肉群参与，例如斯诺克击球。
Mental rehearsal and feedback types link directly to skill classification. When a coach uses visual guidance (demonstration) for a closed, self-paced skill like a golf putt, that’s deliberate — the stable environment allows the athlete to replicate the same movement pattern repeatedly.
心理演练和反馈类型直接与技能分类相关。当教练对高尔夫推杆这种封闭式、自定节奏技能使用视觉指导（示范）时，这是有意的——稳定的环境让运动员可以反复复制相同的动作模式。
9. Guidance and Feedback Terminology | 指导与反馈术语
Guidance is how the coach communicates what to do. Feedback is the information the performer receives about the outcome. OCR often bundles these into scenario-based questions, e.g., ‘Evaluate the use of manual guidance and intrinsic feedback when teaching a beginner to swim.’ You must know the pros and cons of each type.
指导是教练传达动作要求的方式。反馈是执行者获得的关于结果的信息。OCR 经常将这些概念打包成情境题，例如”评估在教初学者游泳时使用手动指导与内部反馈的效果”。你必须掌握每种类型的优缺点。
- Visual guidance — Showing the learner what to do via demonstration, video or diagrams. Best for beginners; gives a mental image to copy.
视觉指导 — 通过示范、视频或图示向学习者展示动作要求。最适合初学者；提供可供模仿的心理图像。 - Verbal guidance — Using spoken instructions to explain a technique. Works best with experienced performers who can translate words into movement.
口头指导 — 使用口头讲解说明技术动作。对能将语言转化为动作的经验丰富的运动员最有效。 - Manual guidance — Physically moving the performer’s body through the correct motion, e.g., holding a gymnast’s legs during a handstand.
手动指导 — 通过身体接触引导执行者做出正确动作，例如倒立时托住体操运动员的腿。 - Mechanical guidance — Using an object or device to assist movement, e.g., a float in swimming or a harness in trampolining.
器械指导 — 使用物体或装置辅助动作，例如游泳中的浮板或蹦床中的保护带。 - Intrinsic feedback — Information coming from the performer’s own senses (how the movement felt), e.g., ‘that golf swing felt smooth’.
内部反馈 — 来自执行者自身感官的信息（动作感觉如何），例如”刚才的高尔夫挥杆感觉很顺畅”。 - Extrinsic feedback — Information coming from an external source, e.g., a coach’s praise, the scoreboard, or a video replay.
外部反馈 — 来自外部来源的信息，例如教练的表扬、记分牌或录像回放。 - Knowledge of results (KR) — Specific feedback on the outcome, e.g., ‘you scored 9.2 on that dive’ or ‘the shot put landed at 12.3 m’.
结果认知 — 针对结果的明确反馈，例如”你那一跳得了 9.2 分”或”铅球落在 12.3 米处”。 - Knowledge of performance (KP) — Feedback on the quality of the movement process, e.g., ‘your elbow was too low on that javelin release’.
表现认知 — 针对动作过程质量的反馈，例如”你掷标枪出手时肘关节太低了”。
An exam-winning phrase to use: ‘Manual and mechanical guidance build confidence and kinaesthethis awareness in beginners, but must be withdrawn quickly to prevent the learner becoming over-reliant.’ Pair this with real sport examples to show depth of understanding.
一个考场金句：”手动和器械指导能建立初学者的信心和动觉意识，但必须迅速撤除以防止学习者过度依赖。” 将这句话与真实运动案例结合使用，可以展示理解的深度。
10. Socio-Cultural and Ethical Terminology | 社会文化与伦理术语
OCR’s socio-cultural topics explore who participates in sport, why, and what barriers still exist. You must handle terms like ‘stereotype’, ‘discrimination’ and ‘inclusion’ with precision and link them to contemporary initiatives like ‘This Girl Can’ or the Paralympic movement.
OCR 的社会文化主题探讨谁参与了体育运动、为什么参与，以及仍然存在哪些障碍。你必须精准使用”刻板印象””歧视”和”包容性”等术语，并将它们与”这位女孩能行”或残奥运动等当代倡议联系起来。
- Stereotype — A widely held but oversimplified belief about a group of people, e.g., ‘women are not strong enough for rugby’. This directly reduces participation.
刻板印象 — 关于某群体广泛存在但过度简化的看法，例如”女性不够强壮不适合打橄榄球”。这会直接减少参与度。 - Discrimination — Acting on prejudice to treat someone unfairly based on their gender, race, disability or socio-economic background within sport.
歧视 — 基于偏见在体育运动中因性别、种族、残疾或社会经济背景不公平地对待他人。 - Inclusion — Proactive efforts to remove barriers and ensure all groups feel welcome and able to participate, e.g., providing ramps for wheelchair access.
包容性 — 主动努力消除障碍，确保所有群体感到受欢迎并能参与，例如为轮椅通行提供坡道。 - Sportsmanship — Ethical behaviour, fairness and respect for opponents and officials, e.g., shaking hands after a game.
体育精神 — 合乎道德的行为、公平竞争以及对对手和裁判的尊重，例如赛后的握手。 - Gamesmanship — Bending the rules to gain an advantage without technically breaking them, e.g., taking too long to serve in tennis to disrupt the opponent’s rhythm.
竞技主义 — 钻规则空子以获取优势，但技术层面上并未犯规，例如网球中故意拖延发球打乱对手节奏。 - Deviance — Deliberately breaking the rules or norms of a sport, e.g., deliberate handball in football or doping.
越轨行为 — 故意违反体育运动的规则或规范，例如足球中的故意手球或使用兴奋剂。
Create a ‘terminology spectrum’ for sportsmanship → gamesmanship → deviance. Picture it as a line from ‘most ethical’ on the left to ‘least ethical’ on the right. When an exam question describes conduct, place it on this spectrum in your mind before selecting the label. This prevents costly hesitation between ‘gamesmanship’ and ‘deviance’.
创建一条”术语光谱”：体育精神 → 竞技主义 → 越轨行为。将它想象为从左端”最合伦理”到右端”最不合伦理”的一条线。当考题描述某种行为时，先在脑海中将该行为放在这条光谱上，再选择对应标签。这能防止在”竞技主义”和”越轨行为”之间犹豫而丢分。
11. Data Analysis and Exam Command Words | 数据分析与考试指令词
OCR PE papers demand more than recall — you will interpret graphs, tables and trends, then use command words to structure your response appropriately. Misreading a command word (e.g., ‘Describe’ versus ‘Evaluate’) is the most common avoidable error in the written paper.
OCR 体育试卷要求的不仅是记忆——你需要解读图表、表格和趋势，然后使用指令词恰当地组织作答。误读指令词（例如把”描述”当作”评估”）是笔试中最常见且本可避免的错误。
- Describe — Say what the data shows without giving reasons. ‘In 2020, participation rose by 12%.’ No explanation yet.
描述 — 说出数据所显示的内容，无需给出原因。”2020 年参与率上升了 12%。” 尚未做解释。 - Explain — Give reasons for the data trend. ‘Participation rose because the ‘This Girl Can’ campaign reduced negative stereotypes.’
解释 — 为数据趋势给出原因。”参与率上升是因为’这位女孩能行’运动减少了负面刻板印象。” - Evaluate — Weigh up positives and negatives, then make a supported judgement. Must show both sides of the argument.
评估 — 权衡正反两面，然后做出有依据的判断。必须呈现论点的正反两面。 - Justify — Give a reason plus evidence to support a choice or recommendation. Use concrete examples from sport.
论证 — 给出理由加上证据以支持某个选择或建议。要引用体育运动中的具体案例。 - Mean, median, mode — Basic statistical measures. Mean is the average, median the middle value when ordered, mode the most frequent value.
平均数、中位数、众数 — 基本统计指标。平均数是算术平均值，中位数是排序后的中间值，众数是出现频率最高的值。
When you see a graph question, spend the first 15 seconds noting the axes labels, the overall trend direction, and any outlier peaks or dips. Then pick the correct command-word vocabulary to build your sentence. For ‘Evaluate’, always include a ‘however’ or ‘on the other hand’ paragraph before your conclusion.
遇到图表题时，先用 15 秒注意坐标轴标签、整体趋势方向以及任何异常峰值或低谷。然后挑选恰当的指令词词汇构建句子。对于”评估”题，在得出结论前始终要写一段”然而”或”另一方面”的内容。
12. Glossary Consolidation: Rapid-Fire Definitions | 术语表整合：速查定义
Use this final table as a rapid revision quiz. Cover the right column, test yourself on the definition, then check. Do this daily for the week before your exam to turn passive recognition into active recall, which is what you need under time pressure.
使用这最后一张表格作为快速复习测验。遮住右列，自测定义，然后核对。在考前一周每天这样做，将被动识别转化为主动回想，这正是你在时间压力下所需的能力。
