15、t in a video. “What we really want is a threedimensional charging experience where you walk into your living room or office and your cell phone is charged simply by walking in.”The process uses magnetic fields to send power to specially designed receivers.Researchers built a 54cubicmeter room in whi

16、ch the walls，floor and ceiling were covered with metal panels.They placed a long metal pipe in the middle of the room.Electrical currents travel up and down this pole about 1.3 million times per second.These currents also move through the ceiling，walls and floor，before flowing again up the pole.Smal

17、l devices inside the pole set the level of electromagnetic waves.These waves continuously move around the room to send power to receiving devices.The Disney researchers said repeated experiments led to successful wireless power transfers to many devices running at the same time.One of the concerns o

18、f electric fields is that they can be harmful to humans.But associate research scientist Matt Chabalko said the level of power being produced inside the room is not dangerous.“Our simulations show that we can transmit 1.9 kilowatts of power while meeting federal safety guidelines.This means its comp

21、 a room is built for wireless charge.BWhat is needed to charge wirelessly.CWhat devices can be charged in the room.DHow wireless charge functions in the room.解析：段落大意题。根据本段的内容可知，本段主要介绍了无线充电的原理，就是把电流转化成磁场，由磁场给电器充电。故选D。答案：D7Why did the author mention the danger of wireless charge?ATo get rid of peoples

22、 worry.BTo remind people of its existence.CTo show the way to solve it.DTo explain how harmful it is.解析：推理判断题。根据第五段的第一句“One of the concerns of electric fields is that they can be harmful to humans.”可知，对电场的担忧之一是电场对人体有害，而后文的“.the level of power.is not dangerous.its completely safe for people”解释说明其无危险并

23、且安全，就是为了消除人们的担心。故选A。答案：A8What benefit might Disneyland bring to its visitors in the future?AVisitors charge their devices cheaply.BVisitors can stay in a safer environment.CTheir cell phones can be charged by themselves.DThe parks can brighten visitors without wires.解析：细节理解题。根据最后一段“One of Disneys li

24、kely uses for wireless power will be to create areas at its parks where visitors can charge their devices.”可知，迪士尼可能会利用无线充电的方法在其公园内创建一个可供游客充电的区域，由此判断出即将来游客走进迪士尼乐园时，他们的手机会自行充电。故选C。答案：CC(2020山西六校二次质检)In elementary school，Glenn Cameron was very aware of the challenges faced by his friend，Roger，who had l

25、ost a hand.Now he has built an artificial helper for him.The robotic hand is called “Dexi”Each of its fingers can move independently.The strength and speed of the hands “muscles” can be controlled.Hes also created a digital version of this hand，which responds on a computer screen.Through a special h

26、eadset，the system takes electrical signals from a human brain，sends them to a computer，and then the computer “tells” the hand what to do.For example，to make the hand close，you “see” a fist in your head.In fact，Camerons first robotic hand was 3D printed online.Realizing the hand was too limited，he de

27、cided to build his own.It was quite a challenge，but his new version was better.It was also cheap，compared to many other robotic hand projects.Cameron says designing and building the hand was hard，but he went on.Then came the one Roger is using.Cameron is working on a hand that can actually be used b

28、y a person whos lost a hand at present.He says the new hand will be simpler，because there wont be as much space.To make up for this，hes adding a mini camera and trying to make the hand smarter.Cameron encourages young people who think they might want to do something demanding and similar，“You just b

29、egin working towards it.Take one little step at a time，purposeful and steadfast，sooner or later youre going to get to the place you long for.”语篇解读在小学的时候，Glenn Cameron看到朋友缺少一只手，内心很受触动，他现在已经制造出了可以由人脑控制的机械手来帮助朋友。9Which version of the artificial hand does Dexi belong to?AThe first. BThe second.CThe thir

30、d. DThe fourth.解析：推理判断题。Dexi出现在第二段，但本题要结合上下文内容来推理才能得到答案。根据第一段的尾句和第二段的开头可知，Dexi是Roger现在使用的机械手版本。第三段谈到Cameron制作的第一个机械手是3D打印出来的，但他不满意。于是，他花费时间制造了第二个版本的机械手，这个版本比第一个要好。但他继续研发，于是便有了第三代机械手Roger现在使用的Dexi。答案：C10How could a user of the digital version of Dexi control the robotic hand?ABy operating the compute

31、r.BBy thinking.CBy sending electrical signals to the hand.DBy speaking.解析：细节理解题。根据第二段的“Through a special headset，the system takes electrical signals from a human brain，sends them to a computer，and then the computer tells the hand what to do.For example，to make the hand close，you see a fist in your h

32、ead.”可知，Dexi的数字版本通过特殊的头部装置，收集大脑发出的电子信号并发送给电脑，电脑“告诉”机械手要做什么。比如，为了把手握起来，你可以在你的脑海中“看到”一个拳头。由此可推知，这个版本的机械手的使用者可以通过“想”来操作机械手。答案：B11Which saying do Camerons words convey?AWell begun is half done.BThe longest journey begins with the first step.CAll things are difficult before they are easy.DNothing is impo

33、ssible to a willing heart.解析：推理判断题。最后一段谈到Cameron鼓励那些想做类似的费力的事情的年轻人：只要开始朝着它努力，一步一个脚印，坚定信念，迟早你会到达想去的地方，即实现目标。D项“Nothing is impossible to a willing heart.(有志者，事竟成)”与他的话所表达的意思一致。答案：D12What is the text mainly about?ACamerons braincontrolled robotic hands.BCamerons story of success.CThe latest designs of artificial intelligence hands.DA robotic helper for the disabled.解析：主旨大意题。全文主要讲了Cameron为帮助失去手的人而设计和制造的机械手，故选A项。答案：A
