　　Mr Clarke was born in a poor family. He was in school for only two years. When he was sixteen he left the poor mountain village and walked to the capital. He had worked in a garden, in a workplace. When he reached the biggest city in the country, nobody gave him any work. He had to beg (乞讨) in the street.

　　One day he was looking for some food while a bag fell off a motorbike. But the rider didn't find it and left quickly. He picked it up and found there was plenty of money in it. There was nobody except him there. He sat by the road and waited for the loser. About half an hour later an old man came back by motorbike and looked for something. The young man returned the bag to him. The old man thanked him very much and told him to work in his shop.

　　Mr Clarke worked hard and watched everything carefully. He learned a lot. With the old man's help , he had a shop. He never fooled anybody and was friendly to the shoppers. And people liked to do the shopping in his shops. Of course he got a lot of money. Now he had several shops, a beautiful house, a few cars and other valuable (值钱的) things. He went to his village and brought his parents, wife and children to the city. How happy they were all when they moved into the beautiful house!

　　Before Mike , their thirteen-year-old son , went to a middle school. Mrs Clarke said ,“Try to be modest (谦虚的) , son. Don't tell anybody that we're rich.”“OK', Mummy,”answered the boy.

　　That morning the teacher told his students to write a composition “My Family”. Mike remembered what his mother had said. So he wrote ,“My family is large. Here're thirteen people in my family.
