ankus

Elephants in zoos and circuses are typically moved with a tool called an ankus, a nasty-looking wooden shaft with a metal hook protruding from the top.It’s banned at the sanctuary.

动物园团里的象被一种叫做刺棒(顶部伸出一个金属钩的巢木轴)的工具驱使，这种工具在保护区禁止使用。

Formerly this mind wandered about as it liked, where it wished and according to its pleasure, but now I shall thoroughly master it with wisdom as a mahout controls with his ankus an elephant in rut.

在过去，著自己的喜好四处飘荡。现在，我将善御己，如象师持钩制伏发狂的象。
