He said that it would be possible to build a platform in the centre of the Channel. This platform would serve as a port and a railway station. The tunnel would be well-ventilated if tall chimneys were built above sea level. In 1860, a better plan was put forward by an Englishman, William Low. He suggested that a double railway-tunnel should be built. This would solve the problem of ventilation, for if a train entered this tunnel, it would draw in fresh air behind it. Forty-two years later a tunnel was actually begun. If, at the time, the British had not feared invasion, it would have been completed. The world had to wait almost another 100 years for the Channel Tunnel. It was officially opened on March 7,1994, finally connecting Britain to the European continent.Expressions1 长21英里的隧道 2 穿越英吉利海峡 3 用作 4 在海平面之上 5 提出 5 一条双轨隧道 6 吸进新鲜空气 在那时 害怕入侵 连接A B under the English Channelserve asabove sea levelput forwarda double railway-tunnel draw in fresh airat the timefeared invasionconnect A to Ba twenty-one-mile tunnelQuestions 1 Who planned to build a tunnel under the English Channel in 1858?
