    清早，我到公园去玩，一进门就闻到一阵清香。我赶紧往荷花池边跑去。

    荷花已经开了不少了。荷叶挨挨挤挤的，像一个个碧绿的大圆盘。白荷花在这些大圆盘之间冒出来。有的才展开两三片花瓣儿。有的花瓣儿全展开了，露出嫩黄色的小莲蓬。有的还是花骨朵儿，看起来饱胀得马上要破裂似的。

    这么多的白荷花，一朵有一朵的姿势。看看这一朵，很美；看看那一朵，也很美。如果把眼前的一池荷花看作一大幅活的画，那画家的本领可真了不起。

    我忽然觉得自己仿佛就是一朵荷花，穿着雪白的衣裳，站在阳光里。一阵微风吹来，我就翩翩起舞，雪白的衣裳随风飘动。不光是我一朵，一池的荷花都在舞蹈。风过了，我停止了舞蹈，静静地站在那儿。蜻蜓飞过来，告诉我清早飞行的快乐。小鱼在脚下游过，告诉我昨夜做的好梦……

    过了一会儿，我才记起我不是荷花，我是在看荷花呢。

      If you had only three years left to live, how would you spend your time? It's a hard question and few of us would even like to think about it. But 18-year-old Huang Ge has to answer this question and he says, “I want to thank the people who have helped me.”
    At the age of one, Huang's mother left the family. Six years later, he was badly ill. He has been using a wheelchair since 9 years old. Doctors said he would only live to 18.After Huang's story went on TV, hundreds of people sent money to help him. The boy was so moved that he decided to thank every one of them. But he has to be tied to his wheelchair. And the family can only afford a three-wheeled motorcycle(三轮摩托). Since 2003, the father and son have traveled 14,000 kilometers, to 10 provinces, and thanked more than 30 helpers.          
    “I am moved by the story of the boy. We need the courage to face death, and we should also show our gratefulness to those who help us,” says an online post on CCTV. com.
