I know of a number of occasions ____ people died from water pollution.
空格里填when,那么整句话怎么翻译呢?occasion在句中又是怎么理解的呢?

occasion 意思是：“ 场合,时机)”.由它构成的词组 on occasion 有时,间或 .可见它是一个偏重于【时间】概念上的词；
people died from water pollution 是定语从句,定语从句中主、谓、宾齐全,先行词 occasions 只能在定语从句中作状语,所以用关系副词 when（= on which）；
句意是：我了解到很多场合/时间,人们因水源污染而死亡.
