many rice fields and woods on both sides of the road. Farmers have built factories, shops and schools in many villages. Between ten and twelve we visited ten families. Many farmers who grew vegetables and raised silkworms became rich. Some families have bought color TV. Their life is much better than before. It’s said that some American friends would come to visit their village, too. I hope the farmers’ life will be better and better.

Hello, everyone. As we know, Many Iraqis become homeless people because of the war.
11
Some of them are children. Some used to be rich but now they lose warm houses and have not enough food to eat. The children have no chance to go to school. The hard living conditions make the homeless children become child laborers. What do you think of their terrible life?
Let’s make a wonderful program to help these children live a normal life. I think we should call on (呼吁) ending the war. We support these poor child laborers by raising money. So they can live in warm houses, get good educations and live happy lives. We hope there will be smiles on their faces. If you’d like to join the program, please come to our community.
