He, should have known that the police would never allow this sort of thing. A policeman approached Jimmy and told him he ought to have gone along a sidestreet as Jumbo was holding up the traffic. Though Jimmy agreed to go at once, Jumbo refused to move. Fifteen policemen had to push very hard to get him off the main street. The police had a difficult time, but they were most amused. 39。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. Fortytwo years later a tunnel was actually begun. If, at the time, the British had not feared invasion, it would have been pleted. 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.Jumbo must weigh a few tons,39。The Hatheld Puffin is a modern aeroplane, but its designer, Mr John Wimpenny, is finding it difficult to get it off the ground. The reason for this is that this plane is also a bicycle. Its pilot has to pedal hard to get it into the air. After Mr Wimpenny had the plane built, it was tested thoroughly. In 1961, it was the first manpowered aircraft to fly half a mile. While being flown by a champion amateur cyclist in 1963, the plane crashed on an airfield. Since then, Mr Wimpenny has had it rebuilt. He has had the length of the wings increased so that they now measure 93 feetalmost as long as those of a Dakota. Many people have shown interest in this new and unusual sport. But though air cyclists may learn how to fly over short distances, and may, eventually, even get across the English Channel, it is doubtful whether they will ever cycle across the Atlantic.Lesson68 Persistent 糾纏不休Hullo, Elizabeth,39。 I39。but I39。s always plenty to read in the 39。 I continued driving and after some time, the examiner tapped loudly.
