The American company Otherlab has built a new drone (无人机) which the company calls “Sky Machine”.

Compared with other unmanned aircraft (无人机), the drone is very different. It is made almost completely out of cardboard. It can be packed with materials and sealed (密封) up with tape.

The drone looks like a big paper airplane that we used to make as kids. But this light flyer is not a toy, it was designed to be dropped from airplanes. Hundreds of drones could be launched at once and then they are guided to where they are supposed to go to complete deliveries (递送) to different places over an area covering hundreds of kilometers.

The company says it can travel about 150 kilometers at speeds up to 88 kilometers an hour. Now it can carry materials weighing up to one kilogram, but future ones are expected to carry heavier loads (负荷).

One of the drone’s main advantages is that it does not have a heavy motor or large battery. This provides more room for materials and makes the drone cost less to build and work.

The technology that guides the drone can make it land within 10 meters of its target, according to Otherlab. And once the drone completes its delivery,  ▲  and the cardboard material will decompose (分解) within a few months.

Otherlab says the drones can also be reused. Otherlab has received money from the U.S. Department of Defense to carry out research on the drones. The U.S. military has a need for delivery drones. But the delivery drones they usually use can be stolen and studied by others if found after use. Before they can truly disappear, the electronic materials inside the drones must also somehow disappear. Otherlab’s Sky Machine is an attempt to fill that need. Researchers are still working on ways to get the technology itself to selfdestruct (自毁).

15. What makes the new drone very different from other unmanned airplanes?

A. It will drop things while flying.

B. It can be played as a toy.

C. Its main material is cardboard.

D. It was made by Otherlab.

16. Having no heavy motor or large battery can _______.

A. make the drone fly faster

B. make it difficult for the drone to land

C. make the drone cost more to build

D. provide more space for carrying materials

17. Which of the following can be put in    ▲   ?

A. it can be thrown away

B. it will go to the next place

C. it can fly back where it lands

D. it will land within 10 meters of its target

18. From the last paragraph, we can learn that _______.

A. the U.S. military is using Otherlab’s Sky Machines

B. the delivery drones the U.S. military uses are always stolen

C. the U.S. Department of Defense supports Otherlab’s research

D. the electronic materials inside a military drone can disappear easily

 

【答案】15. C 16. D 17. A 18. C

【解析】短文介绍了美国的一家Otherlab公司研发了一款叫做“天空机”的无人机。这款无人机与其他无人机非常不同，它几乎完全由纸板制成，没有电机，可以用材料打包并用胶带密封。纸质无人机强行着陆也是可以的，因为它是一次性的。公司表示，无人机也可以重复使用。美国国防部支持Otherlab对无人机的研究，美国军队需要这款无人机，来提高运输的效率。

15. 细节理解题。根据短文中的句子“Compared with other unmanned aircraft (无人机), the drone is very different. It is made almost completely out of cardboard.”可知，这种新型的无人机的主要材料为纸板。故答案为C。

16. 细节理解题。根据短文中的句子“One of the drone’s main advantages is that it does not have a heavy motor or large battery. This provides more room for materials and makes the drone cost less to build and work.”可知，没有重型电机或大型电池，这使得更多的空间可以用于材料，答案为D。

17. 语境理解题。根据下面的句子“and the cardboard material will decompose (分解) within a few months.” (纸板材料会在几个月内分解 )判断，无人机完成它的运输后会被丢弃，答案为A。

18. 细节理解题。根据短文中的句子“Otherlab has received money from the U.S. Department of Defense to carry out research on the drones. The U.S. military has a need for delivery drones.”( Otherlab已接受了美国国防部的投资，对无人机进行研究 )可知，美国国防部支持Otherlab对无人机的研究，答案为C。
