掌握 Pre-U Edexcel 地理的专业词汇，是分析复杂过程、构建循证论述并在笔试和实地考察中获取高分的关键。本指南按主题整理了重要术语，给出精炼定义和记忆技巧，将技术性语言转化为容易记住的模型。
1. Tectonic Processes and Hazards | 构造过程与灾害
Subduction: The process where a denser oceanic plate slides beneath a less dense continental plate and sinks into the mantle. Think ‘sub’ = under, ‘duct’ = lead – one plate is led under another.
俯冲：密度较大的海洋板块滑到密度较小的大陆板块下方，沉入地幔的过程。记忆线索：‘sub’意为下方，‘duct’意为引导——一块板块被引至另一块之下。
Asthenosphere: The semi-molten, plastic layer of the upper mantle on which tectonic plates move. Associate it with ‘asthenos’ (Greek for weak) – it is the weak zone allowing motion.
软流层：上地幔中半熔融的塑性层，构造板块在其上运移。与希腊词根‘asthenos’（虚弱）关联——正是这个软弱带允许板块移动。
Seismic gap: A segment of an active fault that has not experienced a major earthquake for a long period, storing elastic strain. Visualise a quiet gap on a drum skin waiting to snap.
地震空区：活动断层中长时间未发生大地震的段落，积累弹性应变。想象鼓面上一个静默的空隙，等待突然破裂。
Liquefaction: During strong shaking, water-saturated sediments temporarily lose strength and behave like a fluid. Remember ‘liquefy’ – solid ground turns to liquid.
液化：强震时，饱水沉积物暂时丧失强度，表现得像流体。联系 ‘liquefy’（液化）一词——固体地面变为液体。
| Term | Mnemonic |
| Subduction | Sub + duct = led under |
| Asthenosphere | Weak zone = ‘asthenos’ |
| Seismic gap | Quiet drumskin patch |
| Liquefaction | Liquefy → solid becomes liquid |
2. Coastal Landscapes and Processes | 海岸景观与过程
Fetch: The uninterrupted distance of open water over which wind blows, determining wave energy. Picture a bird ‘fetching’ a toy across a wide room – longer fetch, bigger waves.
风区长度：风吹过的开阔水面的连续距离，决定波浪能量。想象一只鸟在宽大房间里‘fetch’玩具——风区越长，波浪越大。
Swash and backwash: Swash is the uprush of water onto the beach after a wave breaks; backwash is the return flow. Swash builds up; backwash strips away. To recall order: first you wash up, then back down.
冲流与回流：冲流是波浪破碎后冲向沙滩的水流；回流是退回的水流。冲流建设海岸，回流剥蚀海岸。记住顺序：先冲上，再退下。
Longshore drift: The zigzag movement of sediment along a coastline caused by waves approaching at an angle. Imagine a leaf drifting sideways across a pond as waves lap at an angle – ‘along the shore’.
沿岸漂移：波浪以一定角度接近海岸时，造成沉积物沿海岸的锯齿状移动。想象一片树叶在波浪斜向拍打时沿池塘边缘漂移——‘沿岸’运动。

Multiplier effect: The knock-on expansion that follows an initial investment, where jobs create more jobs through increased spending. Like a ripple: one drop of investment widens into rings of growth.
乘数效应：初步投资带来的连锁扩张，就业机会通过增加支出创造更多就业。如同涟漪：一滴投资扩展为增长的多层圆环。
Terms of trade: The ratio of export prices to import prices. If export prices rise faster than import prices, terms of trade improve. Remember: export price index / import price index × 100.
贸易条件：出口价格与进口价格的比率。若出口价格比进口价格上涨更快，贸易条件改善。公式：出口价格指数 / 进口价格指数 × 100。

7. Migration, Identity and Sovereignty | 移民、身份与主权
Net migration: The difference between the number of immigrants and emigrants in a given period. Positive net migration = more arriving; negative = more leaving. Simple subtraction.
净迁移：一定时期内境内移入与移出人口之差。正值表示迁入多于迁出，负值相反。简单的减法。
Asylum seeker: A person who applies for protection in another country but whose refugee status has not yet been determined. Think ‘asylum’ = sanctuary; they are seeking safety.
