文档介绍：Once a year a race is held for old cars. A lot of cars entered for this race last year and there was a great deal of excg to discover if this is possible. The spaceship Astra which left the earth a short time ago, will be travelling three hundred miles into space. At a certain point, the Astra will stop for a short time and an astronaut will attempt to leave the stationary spaceship and then return to it. We shall not know whether the experiment has been successful until we have received a radio message. The first message is expected to arrive at 7 o'clock this evening. By that time, the Astra will have been flying through space for seventeen hours and will have circled the earth a great many times. When the first radio messages have been received, the results of the trip will be announced immediately.
Lesson64 The Channel Tunnel 海峡隧道
In l858, a French engineer, Aime Thome de Gamond, arrived in England with a plan for a twenty-one mile tunnel across 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. Recently, there has again been great interest in the idea of a Channel Tunnel. If it is built, it will connect Britain to Europe for the first time in history.
