【简答题】
Since the 1970s, scientists have been searching for ways to connect the brain with computers. Braincomputer interface(BCI) technology could help people with disabilities send commands to machines. Recently, two scientists, Jose Millan and Michele Tavella from the Federal Polytehnic School in Lausanne, Switzerland, show 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 body cells(细胞). These send signals through the spinal cord(脊髓) to the body part to give us the ability to move. But spinal cord injuries(脊柱受伤) or other conditions can prevent these weak electrical signals from reaching the body part.” Tavella says. “Our system allows disabled people to communicate with outer world and also to control machines.” The scientists 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 finds meanings of the signals and commands the wheelchair with an engine. The wheelchair also has two cameras that tell 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 finds meanings of brain signals and turns them into simple commands.” The practical possibilities that BCI technology offers to disabled people can be grouped in two kinds: communication, and controlling objects. 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 get advantages from. And the other is sure that they can use the technology for long. 小题1:BCI is a technology that can________. A.help to make computer systems more modern B.connect the human brain with computers C.help the disabled to be healthier D.control a person’s thoughts 小题2: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 小题3:The team will test with real patients to_________. A.make money from them B.prove the technology useful to them C.make them live longer D.learn about their physical condition 小题4: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 Sickness
