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 to send orders to machines.
Recently,two researchers,Jose Milan and Michele Tavella from the Federal Polytechnic school in Lausanne,Switzerland,showed 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 cases can prevent these weak signals from reaching the muscles,"Tavella says."Our system allows disabled people to communicate with the outside world and also to control machines."
The researchers designed a special cap for the user.This cap picks up the signals from the scalp(头皮) and sends them to a computer.The computer interprets the signals and commands the robotic 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 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.
32.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.
33.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
34.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
35.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.

答案和解析
32.D 细节理解题.根据第三段第一行Tavella operated the wheelchair just by thinking about moving his left or right hand.说明他只是在思考在想,故选D.
33.C 推理判断题.由倒数第二段The researchers designed a special cap for the user.This cap picks up the signals from the scalp(头皮) and sends them to a computer.The computer interprets the signals and commands the robotic wheelchair.The wheelchair also has two cameras that identify objects in its path.They help the computer react to commands from the brain.可知,信号从头皮传到帽子,再由电脑控制轮椅.故选C.
34.B 细节理解题.根据文章倒数第二段The practical possibilities that BCI technology offers to disabled people can be grouped in two categories说明,团队将对真正的病人测试,证明该技术对他们有用的.故选B.
35.C 主旨大意题.文章讲述的是这种技术可以让人用意念来控制自己的行动,这对于那些残疾人是很都帮助的.故选C.
