Verne's Accurate Previw of the Future
Since the beginning of time,man has been interested in the moon.The Romans designed a special day to show admiration and respect to the moon.They called it“Moonday”,or “Monday”,as we know it today.Later,the great mind of Leonardo da Vinci studied the moon and designed a machine to carry a human to the moon.Leonardo said that one day a great machine bird would take a person to the moon and bring great honor to the home where it was born.
Four and a half centuries later,Leonardo's idea was realized.Apollo Ⅱ took three
Americans一Collins,Aldrin,and Armstrong一to the moon.The mission did fill the whole world with great surprise,as Leonardo had said it would.Numerous essays,articles,and books were written about man's first moon mission.But perhaps the most interesting story was one written before the event一over 100 years ago.
In 1865,French author Jules Verne wrote a story about the first journey to the moon.His story was very similar to the 1969 Apollo Ⅱ mission.
Verne's spacecraft also contained three men一two Americans and a Frenchman.The spacecraft was described as being almost the same size as Apollo Ⅱ .The launch site in Verne's story was also in Florida.The spacecraft in Verne's story was named the“Columbiad”aa.The Apollo Ⅱ command ship was called“Columbia”.His account of sending the space-craft into the space could easily have been written about how Apollo Ⅱ was sent into the space.
Verne's story was the same as the actual event in several other respects.The speed of Verne's spacecraft was 36,000 feet per second；Apollo's was 35,533 feet per second.Verne's spacecraft took 97 hours to reach the moon；Apollo's time was 103 hours.Like Apollo's spacemen,Verne's spacemen took pictures of the moon's surface,relaxed on their seats, cooked with gas,and experienced weightlessness.They also came down in the Pacific and were picked up by an American warship.
What were the reasons for Jules Verne's extreme accuracy in describing an event 100 years or more before it actually occurred?He based his writings on the laws of physics and astronomy（天文学）.Nineteenth-century science and the vivid Verne's imagination gave people an unbelievable accurate preview of the greatest events of the 20th century.
Leonardo da Vinci said that a great machine bird would______.
A.bring great honor to the moon
B.fly toward the sun
C.explore the heavens
D.take people to the moon
