Question

An American company has built a new drone（无人机）that could improve the speed of deliveries（送交的货）.

The drone is very different from other unmanned aircraft.It is made almost completely out of cardboard and has no motor.It can be packed with materials and sealed up with tape.

Because the drones do not have a motor,they are designed to be dropped from airplanes.Hundreds of drones could be sent out at once.Then they could be automatically guided to where they are supposed to go.The company says these drones could then complete deliveries to different places over an area covering hundreds of kilometers. The drones look bigger than the paper airplanes we used to make as kids.But this light flyer is not a toy.It is aerodynamically designed and equipped with a small computer,a battery and sensors to guide it to the ground.

The drones are being developed by Otherlab—a technology research company in San Francisco,California.It calls the drone a "Sky Machine."

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 models are expected to carry larger loads.

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

The Otherlab development team has called its invention the "Ikea of drones."This is because it is packaged similarly to products from the Swedish furniture maker Ikea.The drone arrives as flat pieces of pre-cut cardboard that can be quickly and easily put together.

The technology that guides the drone can make it land within 10 meters of its target,according to Otherlab. Unlike other drones,even a crash landing is acceptable.The company says the drones can also be reused.

Once the drone completes its delivery,it can be thrown away and the cardboard material will likely break down within a few months.

The company has received money from the U.S. Department of Defense to carry out research on the drones.The money came from the Defense Advanced Research Projects Agency.The agency is attempting to find the best delivery vehicles that can disappear after their missions are complete.The U.S. military has a need for delivery drones.But it wants to simplify and lower the cost of using them.Otherlab's Sky Machines are an attempt to fill that need.

Military drones can also be stolen and studied by others if found after use.Before they can truly disappear,the electronic materials inside must also somehow disappear.Researchers are still working on ways to get the technology itself to self-destruct.

1.What does Paragraph 3 mainly talk about?

A. Why the new drone is invented.

B. What the new drone is equipped with.

C. How can the new drone get to the ground.

D. Why the new drone is designed like paper airplanes.

2.Why is the invention called the "Ikea of drone"?

A. Because it's a product made by Ikea.

B. Because it uses the idea from Ikea.

C. Because it's built at a low cost like furniture of Ikea.

D. Because it's made up of pre-cut cardboard.

3.Which of the following statements is the advantage of the new drone?

A. It can land near its target.

B. It has a light motor inside.

C. A crash landing is not acceptable.

D. Its load weighs far more than one kilo.

4.What about Otherlab's Sky Machines can be inferred from the last two paragraphs?

A. They have been built by the US military.

B. Research is being carried out on their improvement.

C. They are now often stolen and studied by others after deliveries.

D. The electronic materials inside will destroy themselves after use.

Answer

1.C

2.B

3.A

4.B

【解析】本文主要讲的是一家美国公司已经建立了一个新的无人机，可以提高交货的速度，这架无人机与其他无人驾驶飞机非常不同。无人机还可以重复使用，研究人员仍在研究如何使这项技术自我毁灭。

1.主旨大意题。本文的第三段主要讲的是因为无人机没有马达，所以它们被设计用来从飞机上掉下来，他们可以被自动引导到他们应该去的地方。故选C。

2.细节理解题。根据“The Otherlab development team has called its invention the "Ikea of drones."This is because it is packaged similarly to products from the Swedish furniture maker Ikea.”可知，它被用于宜家。故选B。

3.细节理解题。根据“The technology that guides the drone can make it land within 10 meters of its target,according to Otherlab.”可知，无人机可在目标的10米范围内着陆。故选A。

4.推理判断题。根据“The U.S. military has a need for delivery drones.But it wants to simplify and lower the cost of using them.Researchers are still working on ways to get the technology itself to self-destruct.”可知，研究人员正在实施他们的技术。故选B。

【名师点睛】

推理判断题，求在理解原文表面文字信息的基础上，做出一定的推理判断，从而得到文章的隐含意义和深层意义。推理判断题的题干中一般有infer，suggest，imply，conclude，indicate等标志性词语。如本题的（4）小题。

4. What about Otherlab's Sky Machines can be inferred from the last two paragraphs?

A. They have been built by the US military.

B. Research is being carried out on their improvement.

C. They are now often stolen and studied by others after deliveries.

D. The electronic materials inside will destroy themselves after use.

根据“The U.S. military has a need for delivery drones.But it wants to simplify and lower the cost of using them. Researchers are still working on ways to get the technology itself to self-destruct.”可知，研究人员正在实施他们的技术。故选B。
