题目内容
18.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.
63.What does Paragraph 3 mainly talk about?C
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.
64.Why is the invention called the"Ikea of drone"?B
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.
65Which of the following statements is the advantage of the new drone?A
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.
66.What about Otherlab's Sky Machines can be inferred from the last two paragraphs?B
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.
分析 本文是一篇新闻报道类阅读.文章主要介绍了无人机.无人机叫做Ikea of drone是因为它使用了宜家的创意,文章还简单介绍了无人机的优点,它可以接近目标,而且对无人机改进的研究正在进行.
解答 63-66 CBAB
63.C.段落大意题.根据"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."可知第三段主要讨论了新的无人机怎么到达地面.故选C.
64.B.细节理解题.根据"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."可知无人机之所以叫做Ikea of drone是因为它使用了宜家的创意.故选B.
65.A.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"可知无人机的一个优点是它可以接近目标.故选A.
66.B.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.Otherlab's Sky Machines are an attempt to fill that need."可知研究正在改进.故选B.
点评 本文是一篇新闻报道类阅读.文章主要介绍了无人机.此类题型主要考查学生的细节理解和推理判断能力.细节理解题是针对文中某个细节、某句话或某部分具体内容设置问题,所以在做细节理解题时要结合原文和提干有针对性的找出相关语句进行仔细分析,再结合选项选出正确答案.在做推理判断题时不要以个人的主观想象代替文章的事实,要联系上下文根据文章事实进行合乎逻辑的推理判断.在做段落大意题时考生首先要仔细阅读短文,完整了解信息,准确把握作者观点,确定段落大意.
