Question

The Coolest Inventions

An Oceans Vacuum

There’s a collection of plastic trash in the middle of the Pacific Ocean. It’s bigger than Texas and growing. The way to clean it up now is to catch it with nets. That is both costly and slow. Instead, the Ocean Cleanup Project proposes a 62-mile-long floating barrier that would use natural currents to trap trash. If next year’s trials succeed, a full cleanup operation would aim to start in 2020. It could reduce the trash by 42% over 10 years.

Easy-On Shoes

In 2012, Matthew Walzer, a high school student with a disability, sent a note to Nike. “My dream is to go to college,” he wrote, “without having to worry about someone coming to tie my shoes every day.” Nike assigned a design team to the challenge. This year, they came out with their solution: the FlyEase. The basketball shoe can be fastened with one hand. A pair of Nike FlyEase shoes sells for $130.

An Airport for Drones (无人机)

As Amazon, Google, and others get ready for drone delivery service, there is one big question: What kinds of home bases will their drones have? Rwanda, in Africa, may have the answer. There, workers will soon start work on three “drone ports”. The goals is to make it easier to transport food, medical supplies, electronics, and other goods through the hilly countryside. Construction is set to be completed in 2020.

1.What’s the advantage of the Oceans Vacuum?

A. It can be a money-saver.    B. It can grow year by year.

C. It can tear plastic into pieces.    D. It can be put into wide use soon.

2.What do we know about Nike?

A. It offers free shoes to the disabled.    B. It is designing new shoes frequently.

C. It provides customer-friendly services.    D. It responded to Matthew’s request passively.

3.Why is Rwanda setting up “drone ports”？

A. Because road travel there is rough.    B. Because there are too many drones.

C. Because they’re easier to construct than roads.    D. Because they are receptive to new technology.

【解析】

这是一篇说明文。短文介绍了清理海洋垃圾的新项目，适合残疾人的新产品和新建设的无人机机场。

1.推理判断题。由第一段That is both costly and slow. Instead, the Ocean Cleanup Project proposes a 62-mile-long floating barrier that would use natural currents to trap trash.可知，传统的海洋垃圾清理方式速度慢，成本高。而新的海洋垃圾清理项目利用自然水流捕捉海洋垃圾，这自然会节省资金。故A选项正确。

2.推理判断题。由第二段Nike assigned a design team to the challenge. This year, they came out with their solution: the FlyEase.可知，Nike公司在收到信后，马上组织设计团队解决此问题，并设计出了the FlyEase，解决了问题。由此推断出Nike公司提供方便客户的服务。故C选项正确。

3.推理判断题。由第三段The goals is to make it easier to transport food, medical supplies, electronics, and other goods through the hilly countryside可知，建立无人机机场，是因为这是个多山的国家，陆路交通不便利。故A选项正确。
