套子

The seat-covers on the train had been ripped by vandals.

火车上的座位套子被破坏公物者故意撕破。

Workingmen met at the house of a fencing-master who gave lessons in the Rue de Cotte.

一天，那些花剑头上的套子全去掉了。

My patrolling here is a hindrance to those searching for herbs and scorpions, cutting off their profits.Once I was even shown where they had setup a mantrap!

开始保护长城的时候，那些挖子、药材的人不理解，等于断了的财路，有一次还故意到下有“套子”的地方。
