雅思词汇的积累是一个相当漫长的过程，在忙碌的学习备考的同时我们也会发现很多的乐趣，比如今天小编给大家分享的有趣的雅思词汇介绍：地铁“三文鱼”，让我们一起来边愉快的学习和积累吧。

　　高峰期地铁到站时，我们通常是裹在人流中不由自主地往前走，这时候前方有个人努力地排除万难向地铁方向挤过来，不顾众人的目光，这就是subway salmon——地铁三文鱼。

　　Subway salmons refers to the one or two people who insist on going up a stairway or down a stairway (usually after a train arrives at a subway stop) while all the people leaving the train are going in the opposite direction.

　　地铁三文鱼指的是地铁站里(经常是地铁到站后人大量涌出时)坚持逆着人流上下楼梯的一两个人。

　　Example:

　　"Of course there were subway salmon when I was late for work and I was trying to get out of the subway in a hurry ... Dude, couldn't they tell the train already left?"

　　“上班迟到想赶紧从地铁里出去时总有‘地铁三文鱼’……老兄，难道你看不出地铁已经开走了吗?(还挤个什么劲啊)”
