阅读下面的短文，然后按要求写一篇150字左右的英语短文。

Mayor Bloomberg has been the mayor of New York City for nearly nine years, but for ten years he has been wearing the same shoes. This is really rare to be seen on a billionaire.

“The mayor owns two pairs of work shoes,” said the spokesman. “One day he’ll wear one, the next the other. When they got worn down, he has them repaired. He could buy any shoes he wanted, but he says since they are comfortable, and they work, there’s no need for a new pair.” According to the spokesman, the mayor saves in his footwear and he also keeps it up in his personal as well as governmental finance. “When he buys a cup of coffee, he chooses the smallest size. He buys only what he needs.”

Such is the mayor of New York City, who cares little about his shoes, avoids wasting money and focuses his attention on his work and his people in the city.

But what about our fellow students nowadays? Some wear super expensive clothes and shoes; besides, they buy as many as possible, far more than two pairs. They always want the latest, the newest and throw the old ones away though they haven’t worn them for many times.
