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).
1.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.
2.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
3.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
4.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

Small drones（无人机）can help carry packages to your home. For two years, Google has been working hard in their secret research lab. They have made great progress. Their latest project is called Project Wing. Project Wing is Google’s invention of a drone delivery service. It is half plane and half helicopter（直升机）and is slightly bigger than a seagull. It can deliver packages to customers’ doors.
The first drone test was made on a farm in Warwick, Australia. It sent sweets and dog treats to a farmer. The drone flew to the farm, hovered（盘旋）, and released the package with a wire. Delivery is here!
The best thing about drone delivery services is that delivery times will be greatly cut down. You’ll be able to order online in the morning. And by noon, the delivery drone will deliver you package.
Throughout history, there have been a series of inventions that have helped people move things around, said Astro Teller, lead scientist of Google Wing, to CNN. Teller thinks Google drones will be the next big step in the series.
Interestingly, drones are not that young. The USA has been using armed（武装）drones since 2002. But drones may also get another use. Film companies have asked to use drones to shoot videos from the sky.
Google’s delivery drones won’t be able to fly to customers any time soon. However, Google has proved that drone delivery is possible. And with Amazon announcing their drone delivery service last year, the heat is on to make safe and suitable drones to fly the skies for customers.
1.Paragraph 2 of the reading is mainly about ______.
A.what a drone is B.how a drone works
C.how a drone is produced D.how a drone is designed
2.According to the reading, Project Wing ______.
A.flies very high B.releases the package without a wire
C.is not big in size D.flies faster than birds
3.According to the passage, drones have been in use in the following fields except______?
A.military (军事) B.films C.delivery D.education

A.The new invention can cut down the time of delivery.
B.Astro Teller is the lead scientist of Project Wing.
C.Google drones are the next big step in helping people move things around.
D.Drones will take a long time to deliver a package.

It can help nurses do non-patient-facing tasks so that they have more time for patient care. | B Around the world, 300 million tons of plastic are created each year, and about 10% ends up in the sea. Over 100 million animals in the ocean die each year from being hurt by plastic. | C Scientists has made the “smartest” prosthetic(假体的）hand.The hand uses AI to help it “learn” from users. It’s cheaper than other prosthetic hands, because it uses 3D printing. Each hand is printed based on the users’ needs. |
| D Have you ever seen the watermelon snow？People found the snow was red and smelt like watermelon in the Antarctic(南极)area.The snow has changed its color which caused by a kind of ice-loving algae(雪衣藻). Because of the global warming, the Antarctic is experiencing the very warm temperatures. More algae hold more heat into the snow, which creates more melting(融化). And because the red color of the algae doesn’t reflect back light well, the snow appears red. | E Some rich land becomes desert. We call this process “desertification (沙漠化)”. Desertification affects about 70 percent of all dry land in the world. Over 1 billion people are affected by desertification around the world. That’s about one-sixth of the world’s population. | F Lenovo has introduced a new kind of laptop(手提电脑)called the ThinkPad X1Foldable in 2019.
