A few centuries ago, people looked at the birds and wondered what it would be like to fly like them. There were stories of heroes who glued bird feathers on their arms and flew up into the sky. About 500 years ago, some people dreamed a different dream. Instead of flying up to the sky, they dreamed of falling from the sky!
In the 15th century, Italian inventors designed a cone-shaped (锥形的) device that was supposed to bring a man down safely from a great height. The operator held on to a handle with a strap strapped to his waist. This was the first known design for a parachute(降落伞).
Even the great inventor Leonardo da Vinci sketched a type of parachute. His parachute design was in the shape of a pyramid (金字塔). Other inventors also sketched their own designs for a parachute. Unfortunately, these were only designs on paper and no one tested them.
A Croatian inventor named Fausto Veranzio looked at Leonardo da Vinci’ s parachute design and replaced the pyramid shape with one that looked like a sail from a ship. When Veranzio was 65 years old, he fell ill. Thinking he would not live longer, he decided to try out his parachute invention. He built his parachute using wood and cloth. Strapping his invention to his waist, he jumped off the tall bell tower in his city. He landed safely! He was supposedly the first man to successfully use a parachute. However, some other people thought this story was not true. If that was the case, then the first person to successfully use a parachute would go to a Frenchman named Louis-Sebastien Lenormand in 1783.
As for the first man who successfully used a parachute, ______.
选项
A、it was said to be Leonardo da Vinci
B、we know for sure he was Veranzio
C、there were some historical records
D、we don’t know for sure yet
答案
D
解析
根据第四段最后三句可知,Fausto Veranzio原本被认为是第一个成功使 用降落伞的人,但有些人不这样认为,他们认为第一个使用降落伞的人应该是法国人 Louis-Sebastien Lenormand。由此可推知,关于究竟谁是第一个成功使用降落伞的人, 人们对此还没有确定的答案。故选D。
