But those devices have been firstly designed to help those with disabilities, and are very expensive.“After a while, we figured out that probably the best way is to go for a mass－market way,”says Gaze's Sune Alstrup Johansen. “Where everybody would have this available. ”Johansen and some of his colleagues have formed a new company, the Eye Tribe, which is hoping to develop the technology on a mass commercial level.The technology works with the help of the computing device toward the user's face. After making sure of the user's eye movements, the technology is then able to easily find where a person's eyes are moving, and then allow the eyes to control a cursor(光标)．“Our software can then determine the location of the eyes and know where you're loo king on the screen to make sure what you're looking at, ”reads an explanation on the Eye Tribe site.There has been a gradual change toward hands－free technology in recent years, particularly in the gaming (电玩游戏)world. Recently Xbox released (发布) the Kinect device, which lets users control their Xbox and play certain games using only their hands, legs and voices. But still, most of these devices have been more of a gimmick than a practical way to use one's hands to control a mobile device. Johansen said a replaceable filter(滤光器) would be a cheap, convenient way for most consumers.And even as companies like The Eye Tribe work to create such a product for the average user, making the eye－controlled technology more available and less expensive will have similar benefits for physically disabled users.For more articles on modern science,please CLICK here.文章大意：这篇短文主要介绍了未来社会的一种科技发明,用眼睛操作手机或者电脑.一直致力于研究帮助残障人士用眼睛控制电脑技术的公司Gaze Group打算将该技术应用于适合普通用户使用的领域,这样不但能惠及更多人,同时还能明显降低此类技术的使用费用.1. Which of the following is the main idea of the passage?_C__A. An introduction of a new device.B．An introduction of smart－phones.C．An introduction of eye－controlling technology.D．An introduction of a new technology for the disabled.解析：主旨大意题.根据第一段首句“In thenear future,we may be using our eyes to operate our smart－phones and tablets,”及下文描述,可知本文主要介绍了一种用眼睛操作手机或者电脑的技术.2．The underlined word “gimmick” probably means_A__.A. a trick B．a wayC. a lie D．a dream解析：词义猜测题.联系下文“more...than a practical way to use one's hands to control a mobile device.”可知此处指的是大部分这些装置都是一种噱头(即骗人的把戏).3．According to the passage,we can learn that_C__.A．the eye－controlled technology was first developed for the blindB．the present development of the technology will bring no goodC．there is no such phone as we can use only with our eyes at presentD．the eye－controlled technology is only intended for the disabled people解析：细节理解题.A选项与第二段中的句子“Butthose devices have been firstly designed to help those with disabilities,”不符,“这些设备最早是为残疾人设计的”；而根据倒数第三、四段可知用眼睛操作的电脑不可能是为盲人设计的.根据短文第一段“In the near future,we may be using our eyes to operate our smart－phones and tablets,”可知目前我们还没有这样一部用眼睛控制的电话.4．Thispassageisprobablytakenfrom_D__.A．an experiment B．a science fictionC．a school textbook D．a science website解析：推理判断题.这篇短文主要介绍了未来社会的一种科技发明,用眼睛操作手机或者电脑.根据短文最后一段“For more articles on modern science,please CLICK here.”,CLICK意为“点击”,可知这是一篇网络上的文章,故有可能来自一家网站.B导学号 49152235 What will people die of 100 years from now? If you think that is a simplequestion,you have not been paying attention to the revolution that is takingplace in biotechnology (生物科技). With the help of new medicine,the humanbody will last a very long time. Death will come mainly from accidents,murderand war. Today's leading killers, such as heart disease, cancer, and agingitself,will become distant memories.In discussion of technological changes, the Internet gets most of attention these days. But the change in medicine can be the real technological event of our times. How long can humans live? Human brains were known to decide the final death. Cells are the basic units of all living things,and until recently,scientists were sure that the life of cells could not go much beyond 120 years because the basic materials of cells, such as those of brain cells, would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100,medicine will have advanced to the point at which every 10 years or so,people will be able to take medicine to repair their organs. The medicine, made up of the basic building materials of life,will build new brain cells,heart cells and so on, in much the same way our bodies make new skin cells to take the place of old ones.It is exciting to imagine that the advance in technology may be changing the most basic condition of human existence, but many technical problems still must be cleared up on the way to this wonderful future.文章大意：在未来的100年,人类的生命由于生物科技的发展可以无限期延长的愿望有可能成为现实.5．According to the passage,human death is now mainly caused by _A__.A．diseases and agingB．accidents and warC．accidents and agingD．heart disease and war解析：细节理解题.由文章第一段最后一句可知,当今生命的主要杀手有心脏病、癌症和衰老.6．In the author's opinion,today's most important advance in technology lies in _A__.A．medicine B．the InternetC．brain cells D．human organs解析：细节理解题.第二段前两句的意思是“在讨论技术变化时,人们往往注意到的是网络.然而药学方面的变化可能是当今技术方面的真正事件”,故选A.7．Humans may live longer in the future because _D__.A．heart disease will be far away from usB．human brains can decide the final deathC．the basic materials of cells will last foreverD．human organs can be repaired by new medicine解析：推理判断题.由第二段的后半部分可知,在2050～2100年间,每隔10年左右,人们可以通过服药来修复生病或衰老的器官,这是未来生命延长的原因.8．How long can humans live in the future according to the passage?_D__A．Over 100 years.B．More than 120 years.C．About 150 years.D．The passage doesn't tell us.解析：细节理解题.阅读全文可知,文章没有具体告诉我们人们将来能活多少年.Ⅴ.七选五导学号 49152236根据短文内容,从短文后的选项中选出能填入空白处的最佳选项.选项中有两项为多余选项.Futurologists(未来学家) predict that life will probably be very different in 2050.TV channels will have disappeared._1.G__Today, we can use the World Wide Web to read newspaper stories and see pictures on a computer thousands of kilometers away. By 2050, music,films, programs, newspapers and books will come to us by computer._2.D__Cars will have computers to control the speed and there won't be any accidents. Today,many cars have computers that tell drivers exactly where they are. By 2050, the computer will control the car and drive it to your destination._3.A__Many factories already use robots. Big companies prefer robots—they don't ask for pay rises or go on strike, and they work 24 hours a day. By 2050, we will see robots everywhere—in factories, schools, offices, hospitals, shops and homes._4.C__Today, there are devices(设备) that connect directly to the brain to help people hear. By 2050, we will be able to help blind and deaf people to see and hear again with the help of new technology.Scientists will have discovered how to control genes._5.B__By 2050, scientists will be able to produce clones of people, and decide how they look, how they behave and how clever they are.Scientists will be able to do these things, but should they?A．Robots will have replaced people in factories.B. Scientists have already produced clones of animals.C. Medical technology will have controlled many diseases.D. Cars will run on new, clean fuels and they will go very fast.E. No one can predict what our world will look like in the near future.F. So many changes have taken place in this planet that there will be no life existing on it.G. Instead, people will choose a program from a “menu”and a computer will send the program directly to the television.文章大意：本文主要对2050年人们的生活将会发生哪些变化进行了预测.解析：1．上一句中提到电视频道将会消失,该空应紧承上文,介绍在没有电视频道的情况下人们如何选择电视节目,故选G项.2．第三段主要介绍了2050年的交通,中心词是car.只有D项与这一话题有关.3．第四段主要是围绕机器人的普遍应用展开的,故A项(在工厂里机器人将代替人们来工作)符合该段的语境.4．根据第五段可知,到2050年,盲人和聋人将能在医疗技术的帮助下恢复视力和听力,而不需要像现在一样只能借助某些辅助设备,故用C项(医疗技术将会战胜很多疾病)总领本段.5．最后一段主要是围绕克隆技术展开的.只有B项与该话题有关.。
