[译] 雨和雾都会妨碍飞行。
[误] Raining weather and fog will ban flying.

[正] Raining weather and fog will prohibit flying.
[注] 动词 ban 和 prohibit 都有明令“禁止”涵义，如：Picking flowers in the park is prohibited. 公园里不准采花。/Swimming is banned in the pool. 这个水池不准游泳。如果引申为“妨碍”时，只用 prohibit( = prevent)，又如：His small size prohibits his becoming a boxer. 他身材矮小，妨碍他成为拳击手。
