    题目列表(包括答案和解析)

    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 Millan 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 hand. He could even talk as he watched the vehicle and guided it with his thoughts.

    　　“Our brain has billions 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 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. Millan, 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.

    46. BCI is a technology that can ________.

    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

    47 .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.

    48.Which of the following shows the path of the signals described in Paragraph 5?

    A. scalp → computer → cap →wheelchair

    B. compute → cap → scalp →wheelchair

    C. scalp → cap → computer →wheelchair

    D. cap → computer → scalp →wheelchair

    49.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

    50.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

    　　The research carried out by the University of Bari in Italy could help prove hospitals who are accused of wasting money on art and decoration as it suggests a pleasant environment helps patients ease discomfort and pain．

    　　A team headed by Professor Marina de Tommaso at the Neurophysiopathology Pain Unit asked a group of men and women to pick the 20 paintings they considered most ugly and most beautiful from a selection of 300 works by artists such as Leonardo da Vinci and Sandro Botticelli．They were then asked to look at either the beautiful paintings, or the ugly painting, or a blank panel(板)while the team put a short laser pulse at their hand, creating a sensation as if they had been stuck by a pin．The subjects rated the pain as being a third less intense(剧烈的)while they were viewing the beautiful paintings, compared with when looking at the ugly paintings or the blank panel．Electrodes(电极)measuring the brain's electrical activity also confirmed a reduced response to the pain when the subject looked at beautiful paintings．

    　　While distractions, such as music, are known to reduce pain in hospital patients, Prof de Tommaso says this is the first result to show that beauty plays a part．

    　　The findings, reported in New Scientist, also go a long way to show that beautiful surroundings could aid the healing process．

    　　"Hospitals have been designed to be functional, but we think that their artistic aspects should be taken into account too," said the neurologist．"Beauty obviously offers a distraction that ugly paintings do not．But at least there is no suggestion that ugly surroundings make the pain worse．I think these results show that more research is needed into the field how a beautiful environment can alleviate suffering．"

    　　Pictures they liked included Starry Night by Vincent Van Gogh and Botticellis Birth of Venus．Pictures they found ugly included works by Pablo Picasso, the Italian 20th century artist Anonio Bueno and Columbian Fernando Botero．"These people were not art experts so some of the pictures they found ugly would be considered masterpieces by the art world," said Prof de Tommaso．
