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, Leonardos idea was realized. Apollo II took three Americans, Collins, Aldrin, and Armstrong to the moon. The mission (任务) did fill the whole world with great surprise, as Leonardo had said it would. Numerous essays, articles, and books were written about mans first moon mission. But perhaps the most interesting story was one written before the event over 100 years before. 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. Vernes spacecraft also contained three mentwo Americans and a Frenchman. The spacecraft was described as being almost the same size as Apollo II. The launch (发射) site in Vernes story was also in Florida. The spacecraft in Vernes story was named the “Columbiad”. The Apollo II command ship was called “Columbia”. His account of sending the spacecraft into the space could easily have been written about how Apollo II was sent into the space. 1. Leonardo da Vinci said that a great machine bird would _.
