There is a standing order that I have on file down here.

这里有一份委托书，我已存档。

They filed down the steps and lined up in front of the castle.

他们排成一行走下台阶，排着队站在城堡前面。

Filing a petition down at the courts.

在法庭上提出呈请。

It's a toothbrush, filed down. Very common.

这是一把牙刷，挫平了，很常见的。

And I was simply filing them down and rubbing some graphite on the spikes so that I thought I would run more effectively.

我只是把它们锉平，在钉鞋上擦一些石墨，这样我就能跑得更有效率。

So one thing that we can do in captivity for them is file down those hooks and points in a process we call floating.

所以我们可以在圈养环境中为它们做的一件事就是把那些钩子和尖锉下来，这个过程我们称之为“锉牙”。

They also do it to help them file down their claws or even pull them off, so that a fresh one you can grow.

它们也这样做是为了帮助他们磨掉爪子，甚至可以把爪子给拔出来，这样就可以长出新的爪子了。

What a leg this is! It looks like a real live leg, filed down to nothing but the core; he'll be standing on this tomorrow; he'll be taking altitudes on it.

多好的一条腿啊！看着就像一条活人的真腿，锉得只剩下芯子了；他明天就会用它撑着了；他站在上面可就居高临下了。

He meant this to be ironical, but it was true besides; for the Dodger and Charley Bates had filed off down the first convenient court they came to.

他的意思是讽刺，但除此之外，这是真的；因为道奇队和查理·贝茨已经顺着他们来到的第一个方便的场地鱼贯而去。
