That was the length of the first successful flight (飞行) of Orville Wright and Wilbur Wright’s plane. Wilbur was born in 1867 and Orville in 1871.The Wright brothers developed a strong interest in flight from early childhood. They taught themselves maths and engineering. They started their flying experiments with big kites and gliders (滑翔机) and finally decided to make their own plane. The two brothers worked very hard to make a small engine and a propeller (螺旋桨) for their plane. Their first plane weighed 340 kilograms. Its wings were 12 metres wide. On 17 December, 1903, Orville sat in the plane and made the first successful flight at Kitty Hawk, North Carolina. His flight lasted for only 12 seconds and only covered 37 metres, but this was the first time when human beings successfully sent something heavier than the air into the sky with powered flight. Wilbur also flew the plane on the same day. In the last flight of the day, Wilbur flew for 59 seconds and covered a distance of 260 metres. The Wright brothers improved their plane, and by 1909, it could fly for 32 kilometres. The Wright brothers are surely among the most important inventors of the 20th century. 1．What were the Wright brothers very interested in from early childhood _____ 2．When did the first successful flight take place _____ 3．How long did Orville Wright and Wilbur Wright’s first successful flight last _____ Flight. On 17 December, 1903. 12 seconds. 4．What do you think of the invention of the plane Why do you think so Write 30 words or more. _____ _____ _____ _____ I think it is a great invention for human beings. If there wasn’t the invention of the plane, it would not be so easy to travel to very far places. The invention of the plane lets people find a faster way to go far. Ⅱ阅读理解 Did you know that some of the most useful things we use every day were actually invented by accident Accidental inventions have changed our world in surprising ways. Let’s take a look at three of these inventions! In 1928, British scientist Alexander Fleming returned from holiday, and he noticed something unusual about one of the dishes in his experiment. The dish was full of one group of small living things, except for one area. They stopped growing where there was a mold (霉菌) called penicillin (青霉素). This led to the invention of penicillin, one of the most helpful medicines to this day. In 1866, an American named John Pemberton was trying to create a painkiller. He added soda water to his medicine by chance. After tasting it, he decided to make advertisements for this drink as a soft drink instead of medicine, naming it“Coca Cola”. Since then, Coca Cola has turned into one of the most successful companies in the world. Percy LeBaron S ... ...
