       窗外下着毛毛细雨，我被一道题难住了。唉！该怎么解呢？我坐不住了，就朝雨里走去。     

       在通往乡间的小路上，我遇到了一个大约六七岁的小男孩，他蹲在一个积满了雨水的小水塘边，细雨不停地飘落在他身上，他的头发梢上不断地滴着雨水，可他好像什么也没觉得，

      “小弟弟，你在干什么呀？”我疑惑地问。 

      “造桥呗。”他连头也没抬，只将手中一叠小木头往水塘里排列开去。

      “造啥桥啊？”我好奇地又问一句。  

      “造大桥。”他边回答，边将一块较大的木头往已造好的“桥墩”上放去。  

      “哦，大桥造好啦！大家可以过桥了！”小男孩高兴得跳了起来，“啪”的一声，一脚踩得泥浆溅了开去，“大桥”倒塌了。  

       男孩抓了抓头皮，不声不响地又蹲下来，心疼地捡起木块，重新搭了起来，嘴里还嘟囔着：“这个木头桥不好，我长大了要造座又大又牢的桥。”     

       我被眼前的一切感动了：木头桥虽然没有搭成，可是男孩的心里已建成了一座理想之桥……他那种坚持不懈、刻苦学造桥的精神深深地感动了我，我不禁自问：“难道我就不能像他一样，去解开难题吗？”

       我转身朝回家的路上走去，离小水塘越来越远了，可当我回过头来，透过蒙蒙细雨，隐隐约约看见小男孩还在认真造着“大桥”呢！     

       是啊，每一个人都应该在心灵上建起一座理想之桥。

    Twenty years ago, I drove a taxi for a living. One night I went to pick up a passenger

at 2:30 a.m.. When I arrived to collect, I found the building was dark except for a single

light in a ground floor window.

    I walked to the door and knocked, "Just a minute," answered a weak, elderly voice.

    After a long pause, the door opened. A small woman in her eighties stood before me.

By her side was a small suitcase.

    I took the suitcase to the car, and then returned to help the woman. She took my arm

and we walked slowly toward the car.

    She kept thanking me for my kindness. "It's nothing," I told her. "I just try to treat

my passengers the way I would want my mother treated."

    "Oh, you're such a good man." She said. When we got into the taxi, she gave me an

address, and then asked, "Could you drive through downtown?"

    "It's not the shortest way," I answered quickly.

    "Oh, I'm in no hurry," she said. "I'm on my way to a hospice (临终医院). I don't have

any family left. The doctor says I don't have very long."

    I quietly reached over and shut off the meter (计价器).

    For the next two hours, we drove through the city. She showed me the building where

she had once worked, the neighborhood where she had lived, and the furniture shop that had

once been a ballroom where she had gone dancing as a girl.

    Sometimes she'd ask me to slow down in front of a particular building and would sit

staring into the darkness, saying nothing.

    At dawn, she suddenly said, "I'm tired. Let's go now."

    We drove in silence to the address she had given me.

    "How much do I owe you?" she asked.

    "Nothing." I said.

    "You have to make a living," she answered. "Oh, there are other passengers," I

answered.

    Almost without thinking, I bent and gave her a hug. She held onto me tightly. Our

hug ended with her remark, "You gave an old woman a little moment of joy."
