Some people says that money is not the most useful thing in the world.  But others don't think so.  They think that nothing can be done without money.  So it becomes the most useful thing in the world.

    My father said that money can not only helps people but also kills people.  So you should be careful when you use it.

    I think that money can be used on thousands of things.  I can use it to buy something I like.  So it makes me very happy.

    To be a rich man is most people's dream.  In the past, a lot of people used it to do many illegal things.  My father asked me to follow the law when I use money.  So we should use money carefully and follow the law.
