In 1883，an engineer named John Roebling intended to build a bridge connecting New York with the Long Island. 36 ，experts throughout the world thought it impossible and not 37 . Roebling couldn’t 38 the vision in his mind of this bridge. He knew deep in his heart it could be done. He just had to 39 the dream with someone else. After much persuasion he managed to 40 his son Washington，a young engineer，that the bridge 41 could be built. Working together，the father and son developed concepts of 42 it could be accomplished and how the difficulties could be 43 . With great 44 and inspiration，they hired their crew and began to build their dream bridge. The project started well，but unfortunately an accident took the life of John. Washington was injured and left with a brain damage， 45 him not being able to walk or talk or even move. Everyone had a 46 comment to make and felt the project should be trashed. In 47 of his disability，Washington still had a burning 48 to complete the bridge and his mind was still as 49 as ever. He tried to pass on his 50 to some of his friends. Suddenly an idea 51 him as he lay in hospital. All he could do was move one finger and he decided to make the best 52 of it. By moving this，he slowly developed a code of communication with his wife. He used the method of tapping her arm to tell the engineers what to do. It seemed foolish 53 the project was under way again. For 13 years Washington tapped out his instructions with his finger on his wife’s arm，until the Brooklyn Bridge was finally completed. Perhaps this is one of the best examples of a never-say-die 54 that overcomes a terrible physical handicap and 55 an impossible goal.
