我不喜欢打断上课来练习一些愚蠢的防火演习。

I don't like interrupting my class to practise some silly fire drill.

有一天，因为要防火演习，我们这些源泉公园学校二年级的学生很早就放学了。

One day our second grade class at Spring Park School was released early because of a 2 fire drill.

第三，仅在开发周期使用警告就象使用真正的灭火器来进行防火演习而使用纸杯来扑灭真正的火一样。

Third, using warnings only during the development cycle is like doing fire drills with real extinguishers, then using paper cups to douse the real fire.
