1.（2011•山东卷）D Since the 1970s, scientists have been searching for ways to link the brain with computers. Brain-computer interface(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, Switzerland, demonstrated（展示）a small robotic wheelchair directed by a person’s thoughts. In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right band. He could even talk as he watched the vehicle and guided it with his thoughts. “our brain has billions of nerve ceils. 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 external 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 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 can 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 long periods of time. A. help to update computer systems B. link the human brain with computers C. help the disabled to recover D. control a person's thoughts 72. How did Tavella 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. 73. Which of the following shows the path of the signals described in Paragraph 5? A. scalp→computer→cap→wheelchair B. computer→cap→scalp→wheelchair C. scalp→cap→computer→wheelchair D. cap→computer→scalp→wheelchair 74. The team will test with real patients to A. make profits from them B. prove the technology useful to them C. make them live longer D. learn about their physical condition 75. Which of the following would be the best title for the text? A. Switzerland, the BCI Research Center B. New Findings About How the Human Brain Works C. BCI Could Mean More Freedom for the Disabled D. Robotic Vehicles Could Help to Cure Brain Injuries 【解析】：71-75:BDCBC 【语篇解读】本文是一则新闻报道，介绍了Brain-computer interface(BCI)技术的发明，原理和对残疾人带来的益处。 71.

Edinburgh is faced with the problem of dssposing of(处理)about250,000 Million tons of waster a year . Despite different ways to dispose of much of it in a green manner---largely through encouraging tecycling---its aging facilities such as the Powderhall landfill do not have the ability to deal with it. The European Union(EU) has issued a new policy, regulating how such mountains of waster are to hr disposed of. The five councils (Edinburgh. East Lothian. West Lothian. Midlethian and Borders) face fine around $18million a year from 2013 it they don’t inerease recycling levels and rely less on landfill. With this in mind, the coumlls got together with the idea of building a lage incinerator plant (垃圾焚烧厂)to burn half of the waste produced in their districts. But the plan fell apart after the change of target levels by a new UK government waste policy which required that no more than 25% of the city’s waste should be disposed of in this way by 2025. After the plan was abandoned, a private company which already transported millions of tons of the city’s wast by train to a landfill site near Dunbar, offered an alternative soution when it suggested opening a huge waste site near Portobello. Since Powderhall is supposed to close in 2015, it seemed necessary for the members of the Edinburgh Council to accept the suggestion. But soon they turned it down—after 700 local objections reached them—because it would have meant hundreds of lorries a day making loud noise through heavily populated areas. That still leaves eth council with a problem. By 2013,only50%of 1995 levels of waste will benllewed to be sent to landfill. Even if recveling large are met, there will still be a large amount of rubbish to be burnt up. Due build an Edinburgh and Midlothian councils have
