我们今天用小型挖土机所干的活，若是用镐和铲子，十几个人得花四个月才能完成。
It would have taken a dozen men with picks and shovels four months to do what we've done today, with this comparatively small earth-moving machine.
当我的眼睛习惯了洞中的黑暗之后。我看见地上有一把旧铲子。
After my eyes became used to the dim light in the cave, I saw an old shovel on the ground.
底铁装在鞋后跟上起保护作用的一块铁片，如用铲子挖地时
A metal plate attached to the sole of a shoe for protection, as when spading ground.
只要给他一个桶子和一把铲子，他就高兴极了！
Just give him a bucket and spade and he's in seventh heaven!
