二、复数形式导致词义扩展或抽象化

time | times | 时间 | 时代 / 次数 | Time flies. vs. Ancient times. / Three times. |
三、复数形式导致词性变化（名词→其他词类）
少数名词的复数形式甚至可以改变词性，如变成形容词或副词：

四、特殊注意事项
- 某些复数形式仅用于特定语境
- "waters"（水域）→ territorial waters（领海）
- "sands"（沙滩 / 时间）→ the sands of the desert / the sands of time
- "skies"（天空，诗化）→ under sunny skies
2. 某些名词复数形式保留单数含义，但用法不同
- "fish"（鱼）→ "fishes"（多种鱼类，科学用语）
- "fruit"（水果）→ "fruits"（多种水果，强调种类）
3. 不可数名词的“伪复数”
- "informations"（错误，应为information）
- "furnitures"（错误，应为furniture）
总结
英语名词复数形式的意义变化可分为：
- 词义完全改变（如 air → airs）
- 词义扩展或抽象化（如 people → peoples）
- 词性变化（如 mean → means）
- 特定语境下的复数用法（如 waters, sands）
