9、 we breathe.Thanks to the laws of thermodynamics(空气热力学),cold air can carry less water vapor before it reaches the “dew point” and falls as rain.So while the weather outside may seem wetter,the air itself is drier as it loses the moisture.And researches in the past few years has shown that these dry

15、”。故选D项。BSince the 1970s,scientists have been searching for ways to link the brain with computers.Brain-computer interface (界面) (BCI) technology could help people with disabilities send commands to machines.Recently,two researchers,Jose Milan and Michele Tavella from the Federal Polytechnic school in

16、 Lausanne,Switzerland,demonstrated(展示) a small robotic wheelchair directed by a persons thoughts.In the laboratory,Tavella operated the wheelchair just by thinking about moving his left or right hand.He could even talk as he watched the vehicle and guided it with his thoughts.“Our brain has billions

17、 of nerve cells.These send signals through the spinal cord (脊髓) to the muscles to give us the ability to move.But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles,”Tavella says.“Our system allows disabled people to communicate with the exte

18、rnal world and also to control devices.”The researchers designed a special cap for the user.This head cover picks up the signals from the scalp(头皮) and sends them to a computer.The computer interprets the signals and commands the motorized wheelchair.The wheelchair also has two cameras that identify

19、 objects in its path.They help the computer react to commands from the brain.Prof.Milan,the team leader,says scientists keep improving the computer software that interprets brain signals and turns them into simple commands.“The practical possibilities that BCI technology offers to disabled people ca

20、n be grouped in two categories:communication,and controlling devices.One example is this wheelchair.”He says his team has set two goals.One is testing with real patients,so as to prove that this is a technology they can benefit from.And the other is to guarantee that they can use the technology over

21、 long periods of time.5.BCI is a technology that can .A.help to update computer systemsB.link the human brain with computersC.help the disabled to recoverD.control a persons thoughts答案B解析细节理解题。根据第一段可知,自20世纪70年代以来,科学家一直寻找途径能将人脑与电脑相连。BCI技术能帮助残疾人向机器发送指令。故此处B项正确。而C项只是部分正确,虽然能帮助残疾人,但却不能帮他们康复。6.How did Ta

22、vella operate the wheelchair in the laboratory?A.By controlling his muscles.B.By talking to the machine.C.By moving his hand.D.By using his mind.答案D解析细节理解题。根据第三段可知Tavella只是思考动他的左右手就能操作这个轮椅。甚至当他观察这台机器时就能进行交流,也能用他的思想指导机器人工作。因此机器人是在人脑的思想支配下进行工作的。故D项正确。7.The team will test with real patients to .A.make

23、profits from themB.prove the technology useful to themC.make them live longerD.learn about their physical condition答案B解析推理判断题。根据最后一段第二句“One is testing with real patients,so as to prove that this is a technology they can benefit from.”可知,在患者身上进行实验是他们团队工作的一个目标,旨在证明这项技术对他们有益。故答案选B项。8.Which of the follo

24、wing would be the best title for the text?A.Switzerland,the BCI Research CentreB.New Findings about How the Human Brain WorksC.BCI Could Mean More Freedom for the DisabledD.Robotic Vehicles Could Help to Cure Brain Injuries答案C解析主旨大意题。本文为科技说明文,开篇点题。介绍科学家研究的这项新技术BCI,对残疾人大有裨益。故答案为C项。四、七选五阅读理解(2020全国)A
