      It was a Christmas night. I was an unlucky nurse who had to work on such a beautiful festival. When I was complaining（抱怨）about it, three people appeared at my desk — a tired woman and two children.

    "Are you all sick?"I asked doubtfully because they seemed all right.

    "Yes,"the woman answered weakly and lowered her head.

    But when they started to present their problems, things became unclear. One child had a fever, but his temperature was OK. The other child had an earache, but she could not tell me which ear hurt. It seemed that the mother was pretending（假装）to cough.

    Something was wrong. But I only explained that it might take a while before a doctor could meet them. "Take your time, please,"said the mother. I checked their charts — no address. Suddenly I knew, they were homeless while the hospital was warm.

The family huddled（蜷缩）together under the Christmas tree, smiling and talking with each other sweetly. Quietly, I went back to the nurses'station and told them what happened in the waiting room. It was just like God sending us a gift on Christmas Day. The nurses' station suddenly came back to life. All the nurses went into action for "a Christmas emergency（急诊）".

    We took out our meals for our Christmas "patients". We also put together oranges and apples as presents. We tried to exceed the needs of a family who only wanted a warm place on Christmas night. Later, the little girl kissed me and said, "Thanks for being our angel（天使）."

    The morning was cold and clear. A yellow bus came around the corner and stopped near a wood (树林). A coach asked the students to get off the bus. Girls began to gather by the starting line. One of them is a young, little girl. She had prepared for this running race for the whole summer. She looked around at the other girls, noticing how she was different.

    There was a break in the silence, and everyone started to run. After about twenty-five minutes, every runner finished the race except the girl. She was still running for the next forty minutes. As she came near the finishing line, she saw her parents, classmates and the coach. They shouted her name and told her not to stop until the end. The sweat (汗水) was flowing down her face.

    She kept on running until she crossed the line. I was that girl, and that was the first time I had finished a cross-country race (越野赛跑). Finishing this race made me realize that I could do anything with my own strength. After that, I took more hard work to practice running. I was not a natural-born runner, but I want to become one. I continued to struggle (努力) with every run. Now I run much faster than before and become more and more confident. I am so thankful for running because it has helped make me who I am today.

    Hi, everyone! My name is Guo Ailun. And my English name is Allen. I come from Liaoning, China. I'm 22 years old, and I look really tall and strong. I'm a basketball player. I love basketball very much and I play it quite well.

    My uncle was a great basketball player in the national team (国家队) in the past and my father loves basketball too. So I started to play basketball early. And I began to play for our country as a player when I was only 14. Basketball is my favourite sport. I play it every day. It makes me happy.

    Tony Parker is my favourite basketball player in NBA. I want to be a member of NBA and play with Parker some day. I hope my dream comes true.

    Do you want to be a basketball player like me? Then you must play it hard.

    Larry is going to be a pilot. He wants to fly an airplane. But Larry is not a rich man. He doesn't have an airplane. He has only a chair. Larry ties 45 big balloons to his chair and then sits in the chair. The chair goes up.

    For a few minutes, everything is fine. The view from the chair is beautiful. Larry can see houses and trees below him. He is happy. He is flying!

    The chair goes up very high. Larry is afraid. “I don't want to go very high,” Larry thinks. “I want to go down a little.” With a small gun, Larry shoots 10 balloons. Then something terrible happens. Larry drops the gun, and it falls to the ground. Larry can't shoot more balloons. The chair goes up and up.

    Larry is three miles above the ground. Airplanes are flying over him. Larry has a small radio. “Help! Help!” he says into the radio. “I'm flying in a chair, and I want to come down!” People hear Larry, but they can't help him.

    Larry flies in the chair for 45 minutes. Then the balloons begin to lose air, slowly the chair comes down, and Larry is back on the ground. He is not hurt.
