"Haibao, the mascot(吉祥物) of the 2010 Shanghai World Expo, is very cute, "said Gu Hui, a school kid. "I want a big toy like the mascot."

    Haibao looks like the Chinese word ren, which means people or a person. The name, a typical lucky one in Chinese tradition comes from the Chinese phrase "Si Hai Zhi Bao" —the treasure of the four seas. It also means the treasure of Shanghai, which lies beside the sea.

    Haibao's blue curly(卷曲的) hair looks like the waves of the sea. Its smile is a sign of the healthy spirit of China. Those thumbs-up(翘拇指) will welcome millions of people to Shanghai from around the world. Its big feet show China has the ability to host a successful Expo.

    Haibao was created by two artists, one from the mainland(大陆) and the other from Taiwan. The design is about people living together in the city. The designers want it to fit the theme of the Shanghai Expo, that is, a good life should be created by all the people and people should have harmonious relationships(和谐关系) with nature and society, so that life in cities would be better.

    Surely the mascot will become the lucky symbol and cultural remark of Shanghai Expo.

    We got to another planet and we were on our way back to the earth.

    Suddenly, a UFO appeared and it made our spacecraft land on another planet. On the planet, a very strange-looking alien met us. He took my friends and me to see its master. All the aliens had four eyes, two heads and six legs. They had a white body and no hair.

    The planet looked like a prison (监狱). We were scared and they gave us some food. No one ate the food.

    The next day, they gave us a long list of things to do, but we couldn't understand them at all. They put us in a small room. After that, they did experiments(试验)on us. A few of us died and they put the rest of us back into the room.

    One day, the alien who brought us to our room forgot to lock the door, so we ran away. Soon we flew back to the earth in our spacecraft.

We told people about our experience but no one believed us! After that, I never go into space again.

    Devike was walking home from school. Everything was bad at school. In the morning, she got to school late. In the math test, half her answers were not right and she forgot to do her English homework. The teacher wrote a message in her notebook for her parents to sign.

    She knew her parents would be angry with her. She also knew she had a lot of schoolwork to do. Just thinking about these, she was sad.

    After she got home, her mother gave her a hug(拥抱) and said, "How was your day, dear?" Her little brother Rohit came to her and said," Hi, sister! I miss you.

    Quickly Devika felt better. Of course, her mom would be angry with her poor grades. But she loves her and that is more important. And her little brother always thinks she is smart and beautiful.

    At that time, Devika felt lucky to have such a great family and she didn't worry about her poor grades because the family could comfort(安慰) her when she was sad.

When my daughter was in primary school, she brought home four small twigs(细枝) from school to plant. None of them looked very strong and lively. But with hope for the future, I planted them somewhere in our backyard which could give them enough sunlight. Over the years, because of the poor soil(土壤), three of them died. Only one lived at last.

It grew crooked(不直的) and very slowly. In fact, it looked more like a fat bush than a tree. Later, I noticed that it was starting to die. The branches(树枝) were becoming bare. Only the top third of the tree was still green. I did my best to save it by feeding it a lot of fertilizer, but it didn't work.

Later one morning, I went out and looked at it again. I was thinking if it would be better to just cut it down. It would make the yard look cleaner. As I walked over to take a closer look at it, however, I noticed something moving within the leaves. It was a bird patiently building a nest in the topmost branches. I smiled when I looked at it. I thought maybe this old tree was still useful. It might not be healthy or pretty, but it was still giving a bird a home.

This tree let me know that all of our lives have a purpose. It doesn't matter if we are young and strong or old and sickly. Until our last breath, we have things to do, love to give, and joy to share. We can help to make this world a better and more beautiful place.
