阅读下面短文，从短文后各题所给的四个选项（A、B、C和D）中，选出可以填入空白处的最佳选项。 This is a real life story of the engineers building the Brooklyn Bridge in New York, USA back in 1870. The bridge was completed in 1883, after 13 years. In 1869, a creative engineer named John Roebling was 16 by an idea to build a spectacular bridge 17 New York with the Long Island. 18 , bridge-building experts throughout the world thought that this was impossible and told Roebling to forget the idea. Roebling could not ignore the vision he had in his mind of this bridge. After much discussion and persuasion he 19 to convince his son Washington, an up and coming engineer, that the bridge 20 could be built. The project started well, but when it was only a few months underway, a tragic accident took the life of John Roebling. Washington was also injured and left with a certain amount of brain damage, which 21 him not being able to talk or walk. 22 his handicap, Washington was never discouraged and still had a burning 23 to complete the bridge and his mind was still as 24 as ever. He didn’t want to 25 . Suddenly an idea 26 him. All he could do was move one 27 and he decided to make the best use of it. By moving this, he 28 developed a code of communication with his wife. For 13 years Washington tapped out his 29 with his finger on his wife’s arm, until the bridge was finally completed. Today the spectacular Brooklyn Bridge stands for his determination not to be 30 by circumstances. It stands too as a monument to the love and 31 of his wife who for 13 years long 32 decoded（解码）the messages of her husband and told the engineers what to do. Perhaps this is one of the best examples of a never-say-die attitude that overcomes a terrible physical handicap and achieves a(n) 33 goal. Often when we face obstacles in our day-to-day life, our hurdles(障碍) seem very small in comparison to what many others have to face. The Brooklyn Bridge shows us that 34 that seem impossible can be realized with determination and persistence(坚持), no matter what the 35 are.
