The sappers belt out their song from the campaign in Poland.

工兵在波兰的战役中引亢。

For instance, the woodcutters from the Windsor Castle estate were sent to France as trench sappers.

例如，温莎城堡庄园的伐木工派往法国担任战壕工兵。

Ditto for the sugar in soda and many fruit juices. Above all, stay hydrated: Dehydration is a powerful energy sapper.

汽多果汁中的糖也是如此。最重要的是，一定要补。脱是 让感到疲倦的主要原因。
