Ask any American who invented the airplane and they would say the Wright brothers, but Brazilians would have a different answer. In the Opening Ceremony of the Olympics on Friday, Brazil continued that claim by honoring Alberto Santos-Dumont, the man they credit with the invention.
In 1906, Santos-Dumont flew his plane on the outskirts of France and was recognized around Europe as the creator of the airplane. But Orville and Wilbur Wright later proved that their first flight came three years earlier in 1903.
The question is whether the Wright brothers’ flight should count.
The opinion of many Brazilians is that the Wrights used a catapult and simply created a glider that could maintain a prolonged fall. In 2003, CNN looked into the conflicting claims.
Aviation experts in Brazil claim that the Wright brothers needed strong and steady winds to get the "Kitty Hawk" off the ground, leaving no proof that it was able to take off on its own.
American experts disagree with that claim and say the Wrights’ plane had to have been self-sustaining,
"Even in 1903 the airplane sustained itself in the air for nearly one minute. If it’s not sustaining itself under its own power, it’s not going to stay up that long," Peter Jakab of the National Air and Space Museum told CNN.
Which country really invented the airplane depends plenty on the definition and on the circumstances that the Wright brothers used to get off the ground. The country of Brazil made it clear which side of the debate it is on early in the Opening Ceremony.
Questions 12 to 15 are based on the passage you have just heard.
12.What can we learn about Santos-Dumont?
13.What hinders the confirmation of the creator of the airplane according to the speaker?
14.Why do Brazilians think that the Wright brothers’ flight don’t count as the first one?
15.What was the justification that American experts argued for the Wright brothers’ flight?
选项
A、Because the Wright brothers’ flight could fly only one minute.
B、Because the Wright brothers’ flight didn’t use a catapult.
C、Because the Wright brothers’ flight was self-sustaining.
D、Because the Wright brothers’ flight needed suitable winds to take off.
答案
D
解析
短文中提到,许多巴西人认为怀特兄弟使用了飞机弹射器,而且只是创造了一种滑行,这种滑行呈持续下降的态势。巴西的航空专家认为,怀特兄弟需要强大而稳定的风才能从地面起飞,这就没办法证明他们的飞机可以依靠自己的力量起飞。因此答案为D)。
