To witness immoral behavior in public, one need only visit the Beijing subway.I still remember the first time I took the Beijing subway.It was an early morning.I was in a hurry to go to school.When I was trying to get a ticket, I found a lot of people waiting in front of me, but nobody was in the line.

　　只要访问北京的地铁，就可以目睹公众场所的不道德行为。我还记得我第一次在北京做地铁。那是一个清晨。我急于去学校。当我努力买票的时候，我发现很多人在前面等着，但是没有一个人在排队。
