     When I was in high school, most of my friend had bicycles. I hoped I could also have it.

     One day I saw a second-hand bicycle, that was only one hundred yuan. I ask my father the

money. But he said he could only give me half of the money. He should find the other half myself.

     So I went to sell newspapers after the school. My father was pleased if I showed him the money

a month late. He gives me the other fifty. You can imagine how much happy I was when I rode to

school on my own bicycle.
