16．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．
12．How did Tavella operate the wheelchair in the laboratory？D
A．By controlling his muscles．
B．By talking to the machine．
C．By moving his hand．
D．By using his mind．
13．Which of the following shows the path of the signals described in Paragraph 5？C
A．scalp→computer→cap→wheelchair
B．computer→cap→scalp→wheelchair
C．scalp→cap→computer→wheelchair
D．cap→computer→scalp→wheelchair
14．The team will test with real patients toB．
A．make profits from them
B．prove the technology useful to them
C．make them live longer
D．learn about their physical condition
15．Which of the following would be the best title for the text？C
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． 试题答案
分析 本文是一则新闻报道，科学家寻找到了一种方法，把人脑与电脑连接起来，进而发明了Brain-computer interface（BCI）技术的发明，文中介绍了它的原理和对残疾人带来的益处．
解答 12．D．细节理解题．根据第二段"Tavellaoperated the wheelchair just by thinking about moving his left or right band．"可知Tavella是用他的头脑在实验室操作的轮椅．故选D．
13．C．细节理解题．根据第五段The researchersdesigned a special cap for the user．This head cover picks up the signals fromthe scalp（头皮） and sends them to a computer．Thecomputer interprets the signals and commands the motorized wheelchair．Thewheelchair also has two cameras that identify objects in its path．They helpthe computer react to commands from the brain可知信号的路径是头皮→帽→计算机→轮椅．故选C．
14．B．细节理解题．根据最后一段"to prove thatthis is a technology they can benefit from．"，证明他们可以从中获得的好处．故选B．
15．C．主旨大意题．本文是新闻文体，因此要关注首段的中心，由首段的第二句话"Brain-computer interface（BCI） technology could help people withdisabilities send commands to machines．"可知bci可能意味着残疾人更多的自由；故选C．
点评 考察学生的细节理解和推理判断能力，做细节理解题时一定要找到文章中的原句，和题干进行比较，再做出正确的选择．在做推理判断题不要以个人的主观想象代替文章的事实，要根据文章事实进行合乎逻辑的推理判断．
