BMW是指人们出门上班时先乘坐公交车到达最近的地铁站，出了地铁以后再走一段才到达他们的目的地。那么，你是“BMW族”吗？

In many western cities, the subway is called the "Metro". Many people go to work by taking a bus to the nearest Metro station. After they get off from the Metro, they walk a few blocks before arriving at their final destination, thus the sequence: Bus Metro Walk (BMW). Those who go to work by this BMW are called BMW people.

在很多西方城市，地铁都叫做Metro。很多人出门上班时都是先乘坐公交车到达最近的地铁站，出了地铁以后再走一段才到达他们的目的地。这样的出行方式就叫做BMW（公车、地铁、步行），以此方式出行的人就叫做“BMW族”。

For example:

When asked how he gets to work everyday, a colleague of mine used to say: “I get here by BMW.”
被问到每天怎么上班时，我一个同事回答说：“我是公交、地铁然后步行来的。”
