Unit 5 Great inventions
一、阅读理解，本大题共5小题，每小题4分，共20分。阅读下列短文，根据短文内容选择最佳选项。
“Run, run, run!” your instructor shouts in your car. You try your best and keep your balance as you run fast across the grass. The wind fills your paragliding （滑翔伞） wing. Soon, you jump off the ground and start flying. This is your first paragliding trip!
Paragliding is a kind of human flight （飞行） that starts with your feet and lets you fly like a bird. The idea of human flight goes back to Leonardo da Vinci, but modern paragliding got its start from NASA．Back in the 1960s, NASA needed to find a way to help spacecraft （航天器） return to Earth safely. A pilot named David Barish created a lightweight parachute （降落伞）。 NASA didn’t use it at last, but Barish’s design helped start the sport of modern paragliding.
Now, paragliding wings are stronger, safer and easier to use. People keep setting new paragliding records. In fact, the latest world record for the farthest flight is over 600 km!
Paragliders can put everything they need into one bag that usually weighs between 10 and 25 kilograms. But if you are a beginner, it’s best to fly with a coach. A coach can help you manage some difficult situations. This way, you can relax and enjoy the ride.
Does it sound fun Don’t just dream about flying freely. Get ready, run, lift off and discover the fun of paragliding!

【导语】本文是一篇说明文，主要介绍了滑翔伞运动，包括其起源、发展、装备以及初学者注意事项等内容。
1.第一段描述了“你”在教练的呼喊下，尽力保持平衡在草地上快速奔跑，随后借助滑翔伞起飞的刺激经历，直接说明作者是通过描述一个令人兴奋的经历来开始文章的。
2.第二段提到“A pilot named David Barish created a lightweight parachute （降落伞）。 NASA didn’t use it at last, but Barish’s design helped start the sport of modern paragliding.”，这里“it”所在句子表示NASA最后没有使用它，结合前文可知“it”指代的是David Barish设计的轻型降落伞，即David Barish’s design。
3.第三段提到“People keep setting new paragliding records. In fact, the latest world record for the farthest flight is over 600 km！”，人们不断创造新的滑翔伞记录，最新的最远飞行世界纪录超过600公里，由此可以推断出滑翔伞运动员正在取得惊人的成就。
4.第四段提到“But if you are a beginner, it’s best to fly with a coach. A coach can help you manage some difficult situations.”，说明初学者最好和教练一起飞，因为教练可以帮助处理飞行中的一些困难情况，即教练可以在飞行中解决难题。
5.第一段通过描述滑翔伞的刺激体验引入主题；第二段讲述滑翔伞的起源；第三、四段介绍滑翔伞的发展、装备以及初学者注意事项；第五段总结鼓励人们去体验滑翔伞的乐趣。所以文章结构是①/②/③④⑤。
