【题目】 An engineer named John Roebing thought of an idea to build a bridge connecting New York with the Long Island. He shared his idea with building engineers throughout the world, but no one was interested and they asked John to forget about it. According to them, it was a very difficult task and impractical to be done.

However, John could not forget the picture he had in his mind of the bridge. He thought about it day and night and wanted to share it with someone who would believe in his idea. John's son Washington Roebling was a young engineer then. He believed in his father and thought that the bridge could be built.

John and Washington, working together for the first time, developed plans of how the bridge could be built. They hired(雇佣) their workmen and began to build their dream bridge on January 3rd, 1870.

The project started well, but after a year, a terrible accident took John Roebling’s life. After that, Washington began to take charge of the bridge. However, after a few months Washington was seriously hurt, and it caused him brain damage. He was not able to walk or talk. The building of the bridge stopped.

Everyone around him lost hope about the future of the project. “We told them so.” “Crazy men and their crazy dreams.” These words hurt Washington, who still lay in hospital. However, his dream was still alive. He wanted to get up and continue his work, but his poor health did not allow him to. At that time, Washington could move only on finger and this gave him an idea. He tapped(敲打) that finger on his wife Emily’s arm, meaning he wanted her to call back the engineers. Then he used the same method to tell the engineers what to do.

For the next 11years, Washington gave instructions(指示) by tapping on Emily’s arm and she patiently passed on his message to the engineers. The bridge was finally completed and opened with a big celebration in May 1883.

Today, the 5,989 feet Brooklyn Bridge stands over the East River as one of the best examples of human will and love.

1What was Washington Roebling?

2What happens to John Roebling one year after the project started?
