4、predictably,and affects so many of us,that its hard to believe that scientists have had very little idea why cold weather helps germs to spread.Worldwide,up to five million people catch the illness each flu season,and around a quarter of a million die from it.Part of its power comes from the fact th

5、at the virus changes so quickly that the body is hardly prepared.“The antibodies weve built up no longer recognize the virusso we lose our immunity,” says Jane Metz at the University of Bristol.It also makes it harder to develop effective vaccines,and even if one comes out,governments often fail to

6、persuade enough people to take it up.The hope is that by understanding better why flu spreads in winter,but naturally fades in summer,doctors could find simple measures to stop its spread.Previous theories had centred on our behaviour.We spend more time indoors in the winter,meaning that were in clo

7、ser contact with other people who may be carrying germs.Another popular idea concerned our physiology(生理机制):the cold weather weakens our bodies defenses against infection.In winter,without much sunlight,we may run low on Vitamin D,which helps power the bodys immune system.Moreover,when we breathe in

8、 cold air,the blood vessels in our nose shrink,which affects the normal function of white blood cells,allowing viruses to slip past our defenses unnoticed.While such factors both play some role,analyses suggested another ignored cause may have been lying invisible in the air that we breathe.Thanks t

9、o 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 conditions seem to o

10、ffer the perfect environment for the flu virus to flourish.In wetter air,the epidemic struggles to build strength,while in drier conditions it spreads like wildfire.And comparing 30 years climate records with health records,Jeffrey Shaman at Columbia University found that flu epidemics almost always

11、 followed a drop in air humidity.1.What can we infer from the second paragraph?A.We lose immunity due to the absence of our antibodies.B.The antibodies fail to function due to variation of virus.C.Government should come up with better ways to persuade people.D.One in four of the infected die from th

15、70s,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 Lausanne,Switzerlan

16、d,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 of nerve cells.Thes

17、e 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 external world and also

18、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 objects in its path

19、.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 can be grouped in two

20、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 long periods of tim

21、e.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 Tavella operate the wh

22、eelchair 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 profits from themB.p

23、rove 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“Oneistestingwithrealpatients,soastoprovethatthisisatechnologytheycanbenefitfrom.”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 following would be the best title for the
