nail中等

Nearly 2,000 years ago, as the Romans began to pull out of Scotland, they left behind a curious treasure: 10 tons of nails, nearly a million of the things.

大约2000年前，罗马人开始撤出苏格兰时，留下了一批奇特的宝藏：10吨钉子，将近一百万枚。

The nail hoard was discovered in 1960 in a four-metre-deep pit covered by two metres of gravel.

这批钉子于1960年在一个四米深的坑中被发现，坑上覆盖着两米厚的碎石。

Why had the Romans buried a million nails?

罗马人为什么要埋下一百万枚钉子呢？

The Romans buried the nails so deep that they would not be discovered for almost two millennia.

罗马人把钉子埋得很深，以至于近两千年都未被发现。

Later civilisations would value the skilled blacksmith’s labour in a nail even more than the raw material.

后来的文明对一枚钉子中熟练铁匠所付出劳动的重视，甚至超过了对原材料的重视。

This was an attempt to recover the valuable nails, which could be reused after sifting the ashes.

这是为了回收宝贵的钉子，这些钉子从灰烬中筛出后可以再次使用。
