问题    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) device that was supposed to bring a man down safely from a great height. The operator held on to a handle with straps 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 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. Straping 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 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. [br] 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 推理题。关于谁是第一个成功使用降落伞的人，根据文章第四段最后两句可知，有些人认为法奥斯托-范拉诺的故事不是真的。第一个成功使用降落伞的人可能是一位名叫路易斯-塞巴斯蒂安-勒诺尔芒的法国人。故选项D(我们现在还不能确定)正确。选项A(据说是列奥纳多-达-芬奇)错误，文中第三段只指出了达-芬奇绘制了降落伞的草图。选项B(我们非常确定是法奥斯托·范拉诺)与第四段最后两句意思不符。选项C(有一些历史记录)原文未提及，故本题选D。
