在加拿大,人们常常可以看到有些工程师、设计师、专家、学者戴有一种不起眼的钢戒指。这是为什么呢?原来,这是用以纪念历史上一次惨痛教训的。据说,过去有一名加拿大工学院毕业的工程师设计了一座钢桥,由于设计不合理,大桥完工后不久就坍塌了。为了让人们记住这次教训,加拿大工学院决定,凡是工科毕业生都发给一枚用这座钢桥上的钢制成的戒指。因此,人们看到佩戴这种戒指的人就知道他们是加拿大工科学院的毕业 In Canada, one can often see that some engineers, designers, experts and scholars wear a humble steel ring. This is why? Originally, this is to commemorate the history of a painful lesson. It is said that in the past, a graduate from the Canadian Institute of Technology designed a steel bridge, due to unreasonable design, the bridge collapsed shortly after completion. In keeping with this lesson, CANT decided that all engineering graduates would send a ring made of steel from the steel bridge. So people see the people wearing the ring know that they are graduating from the Canadian Academy of Engineering
