Most Americans enjoy moving from place to place. For example, they often drive their cars 120 to 160 kilometers away just to have dinner with a friend or even fly to Europe just for watching a football match. In some states only one person in five lives in a place for more than five years. One may be born in one city, and go to school in another. He may finish his middle school in two or three cities, and then attend a college far across the country. When he has entered business, he may possibly move from job to job. Moving from one job to another, which is called “job-hopping”, is a very common practice in the United States. Job-hopping does good to workers, because every change of a job gives them a chance to move up to a higher position and to get better pay. And job-hopping also gives bosses the chance to get new ideas and skills that different people bring to their companies and factories.

When an animal helps another animal, it usually gets something valuable in return. For a long time, many scientists thought that only people could act generously just because it feels good.
However, a new study in Germany suggests that chimpanzees (黑猩猩)also do good things for no real reason. And so do children who are as young as 18 months of age. Maybe it is because humans and chimpanzees share an ancestor(祖先) about 6 million years ago.
People and chimpanzees appear to develop such features(特征) without any other training, says Warneken, a scientist in Germany. Warneken and his partners worked on adult chimpanzees that live on an island in the African country of Uganda. They also worked with 18-month-old children in Germany. The researchers performed three experiments on the adult chimpanzees and two experiments on the kids. In the first animal experiment，a person tried to reach his arm into a cage to get a stick，but he couldn’t reach it. A chimpanzee was in the cage，and it could reach the stick if it wanted to.
Thirty-six chimpanzees took part in this experiment one by one, and no chimpanzee saw what the other chimpanzees had done. Even though the animals hadn’t met the person before, they usually took the stick and gave it to the person. What’s more, they did this whether or not the person offered them bananas as a reward. In a similar experiment, 36 children acted in a similar way. They helped the person reach the stick, whether or not they were offered toys for their help.
Researchers did other experiments on chimpanzees and babies. No rewards were offered in either experiment. And still, both the chimpanzees and children went out of their way to help. Still, the new study is different from earlier findings. Researchers have found that chimpanzees don’t give rewards of food to other chimpanzees, even if it costs them nothing to be generous.

Ma Yan is not really a writer, but this 15-year-old girl has written a book that has moved many people around the world. Ma Yan’s diary tells us about Ma’s life. She lives in a poor village called Zhangjiashu in Tongxin, Ningxia, and she has no money to go to school. However, she is brave and wants to go to school very much.
Her mother gave her diary to a reporter, Pierre Haski when he went to Zhangjiashu in 2001. Now, Ma Yan’s diary has been published in France, Italy, Germany, Japan and China.
Ma Yan is now a Junior Three student at Yuwang Middle School in Tongxin. Before this, she had to drop out of school twice. She had to stop going to school the first time, because her mum told her there was no money for her to go to school. She worked for 21 days and saved 13 yuan. With this money, she went back to school. The second time, her family told her she had to leave school while her two brothers could stay.
“I want to study,” Ma Yan wrote in her diary. “Why can boys study but girls can’t? It would be wonderful if I could stay at school forever.”
Ma Yan loves school so much because she wants to have a better life.
“My parents work hard in the fields but they are still poor. They have no knowledge(知识). Most girls in my village leave school early and get married young. I don’t want that kind of life,” Ma Yan said.
After her story became known, many students sent money to her. She hopes to go to Tsinghua University and become a reporter. “Then, I can find poor kids like me, and help them,” she said.
