面的] comments and felt that the project should be scrapped[抛 弃] since the Roeblings were the only ones who knew how the bridge could be built. In spite of his handicap[身体的不便] Washington was never discouraged and still had a burning desire to complete the bridge and his mind was still as sharp as ever. He tried to inspire and pass on his enthusiasm[激情] to some of his friends, but they were too daunted[气馁的] by the task. As he lay on his bed in his hospital room, with the sunlight streaming through the windows, a gentle breeze blew the flimsy[薄薄的] white curtains apart and he was able to see the sky and the tops of the trees outside for just a moment. It seemed that there was a message for him not to give up. Suddenly an idea hit him. All he could do was move one finger and he decided to make the best use of it. By moving this, he slowly developed a code of communication with his wife. He touched his wife's arm with that finger, indicating to her that he wanted her to call the engineers again. Then he used the same method of tapping her arm to tell the engineers what to do. For 13 years Washington tapped out his instructions with his finger on his wife's arm, until the bridge was finally completed. Today the spectacular Brooklyn Bridge stands in all its glory as a tribute to the triumph of one man's indomitable[不屈不挠的] spirit and his determination[坚定] not to be defeated by circumstances. 〖预览〗 一根鱼竿和一篓鲜活硕大的鱼——哲理故事 从前，有两个饥饿的人得
