Key: If I were a billionaire, I would build a vocational school for street children. The following are the reasons of my decision. First of all, street children are very poor. They have no job, no home, very little money. Their lives are unstable in streets. In addition, street children are helpless. They are put aside society. Their bad destinies are always in danger. Finally, street children are the results of the mistakes of adults. They are innocent. Therefore, they are worth of being helped to have a chance for a better life. It is the above mentioned things that I decide to build a vocational school for helping street children when I become a billionaire.
