Lesson 66 Sweet as honey! 像蜜一样甜！ - 词汇深度分析报告
课文原文
**Lesson 66: Sweet as honey! 像蜜一样甜！**
**参考译文：**
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 man-powered 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 feet—almost 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.
“哈菲尔德海鹦”号是一架现代飞机，但它的设计者约翰·温佩尼先生发现很难让它离开地面。原因是这架飞机同时也是一辆自行车。它的飞行员必须用力蹬踏才能让它升空。在温佩尼先生让人造好这架飞机后，它经过了彻底的测试。1961年，它成为第一架飞行半英里的人力飞机。1963年，当这架飞机由一位冠军业余自行车手驾驶时，它在机场坠毁了。从那以后，温佩尼先生让人重新建造了它。他让机翼的长度增加了，所以现在它们有93英尺长——几乎和达科他飞机的机翼一样长。许多人对这种新颖而不寻常的运动表现出兴趣。但是，尽管空中自行车手可能学会如何在短距离飞行，最终甚至可能飞越英吉利海峡，但他们是否能骑自行车横渡大西洋还是令人怀疑的。
