Many people believe that yellowing and wetness are the greatest enemy of stamps. In fact, stamps are afraid of not only wetness, but also light and dirty things. People protect their stamps in several different ways.

 To protect stamps,we should never touch the stamps with our hands.This avoids moving dirty things onto them. Stamp tweezers (镊子) should be used in all conditions.

 Stamps are printed things. The colour will slowly disappear if the stamps are put in the light for a long time. So we should not put stamps in the light for long. Direct sunlight must be avoided as well.

 Wetness is an important  problem for stamps. Some  collectors  will put stamps  in separate plastic (塑料) bags. However, it is possible that some stamps have taken in some water from the air before they are put into the plastic bags.Stamps yellow easily and rapidly after they take in wet air.To protect the stamps, some people also put the stamps into a special room which has a machine to  keep the air cool and dry. However, not many people can afford that.

 To keep stamps, stamp collectors usually put them under plastic covers. It is a common and simple way. This helps because the plastic cover keeps the stamps off the wet air. It also stops the fingersfrom touching te stamps.

 Some  collectors  prefer  to  store  stamps  inside  a  plastic  box  with  desiccants  (干燥剂).However, we should take care not to let the stamps. touch the desiccants. On top of that, don't  take your stamps out on a wet day.

    Travel can teach kids more than a textbook. Travelling with kids is good for them. They can find new interests. Travel makes information alive for kids, and makes it much more exciting than studying textbooks or doing experiments in the laboratory. While travelling, they learn how to deal with new situations, and communicate with other people. They learn patience, because sometimes it takes a long time to get to some exciting or interesting places.

    I've been travelling since I was seven years old. For me, to stop travelling would be like taking something away from my soul（灵魂）. I can't live without travelling. Some people think it's hard to travel after having kids. But in my opinion, when people become parents, it doesn't mean they can't travel any more. My children have been travelling since they were three weeks old.

    Bringing a new life into the world comes with many responsibilities（责任）and I'd love to be a good mother. One of my duties is to educate my children. I'm so thankful that my parents took me on family trips when I was young. I've learned that the outside world is more colorful than the little one I was living in. Of course, I want to pass these travel experiences on to my children.

    I value the memories I have travelling with my children. I'm sure they will always remember them in their lives.

    In the Middle Eastern country of Lebanon, there are more than 1 million refugees (难民). Youssef was 10 years old when a local Syrian musician discovered his talent: a deep, powerful voice-well-suited to traditional songs. However, Syria's civil war took place soon. He and his family lost their home.

    When the Action for Hope Music School announced that it was looking for talented children to train, his family encouraged him to attend the school. A year and a half later, Youssef, with another 11 children, was chosen to take part in a concert.

    Youssef, a shy boy, was a lead singer in the concert. He gave a confident performance of traditional Syrian songs. "We only heard the sound of a mortar(迫击炮）. It fell near us. A whole building came down. That is all I remember," said Youssef. "Music makes me forget everything. Music is the most important thing."

    Basma, director of Action for Hope, said," The music school offers children who suffer from the war strength (力量). They can find a good way to express themselves and stop thinking of themselves as refugees."

    "Art gives strength. It comes from the ability to create," Basma said, "People who are in difficult conditions need this strength much more than the rich."

    Last year, Tom left school. He went to Beijing to look for(寻找) a job. He went from one company(公司) to another. But he didn't get one. He had only a little money. So he had to go back to his home. Then he came to the train station.

    When he got to the train station at night, there were many people buying tickets at the station He bought the last ticket. He felt happy.

    At that time, a young woman with a baby walked to him. She asked him to sell her the ticket. Tom gave her the ticket, because he thought they needed it more. After the train left, he didn't know where to go. Just then, an old man came to him and said, "Young man, I saw what you did to the woman. I have a big company. I need a good young man like you. Would you like to work for me?" Tom was so excited that he couldn't say a word.
