语感
ability = 现有能力，capability = 潜在能力，capacity = 容量上限
能力才能本领
三词都译为「能力」，但场景不同。ability to do sth. = 你现在就能做；capability = 条件具备后能做（has the capability to expand）；capacity = 能承受多大量（capacity for learning）。高考写作里描述个人能力用 ability to do 最稳，不要换成 capability 或 capacity。
陷阱
⚠️ability 后接结构错误
✗
She has the ability of solving problems.
她有解决问题的能力。
ability 后接 to do，不接 of doing
✓
She has the ability to solve problems.
她有解决问题的能力。
⚠️ability vs capacity 混用
✗
The factory has the ability to produce 1,000 units per day.
工厂每天能生产1000件。
指最大产量/承载量时用 capacity，不用 ability
✓
The factory has the capacity to produce 1,000 units per day.
