Lesson64 The Channel Tunnel
In l858, a French engineer, Aime Thome de Gamond, arrived in England with a plan for a twenty-one-mile tunnel under the English Channel. 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.

練習感悟：
音標是需要復習至少一輪的含长，雖然練完音標會形成肌肉的慣性券腔，但是只有記下音標的發(fā)音關鍵，才能在每一次練習時拘泞，立即調整發(fā)音纷纫，形成正確的肌肉慣性。
一句話陪腌，就是干辱魁。
