天災人禍難預料，不未雨綢繆，往往逃生希望渺茫。學謝爾頓準備“緊急求生包”，有備無患！

Bug-out bag is a bag that contains items needed in an emergency and that is ready for a person to take if they have to leave quickly in the event of a disaster.

“緊急求生包”即裝有在緊急情況下需要物品的包，發(fā)生災難需要迅速逃生時可以背上就走。

Example:

During his presentation, Mr. Charles suggested that a well-prepared bug-out bag was only part of the equation: just as important was knowing where to go.

查爾斯先生在演講中說到，準備好一個“緊急求生包”只是成功的一半，同樣重要的還有知道逃生到哪兒。
