     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 hand.

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.

1. BCI is a technology that can ________.

A. help to update computer systems

2. How did Tavella operate the wheelchair in the laboratory?

A. By controlling his muscles.

B. By talking to the machine.

C. By using his mind

3. 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. cap→computer→scalp→wheelchair

D. scalp→cap→computer→wheelchair

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. Robotic Vehicles Could Help to Cure Brain Injuries

D. BCI Could Mean More Freedom for the Disabled

飞机设计师曾经在设计飞机时遇到一个难题，即如何保证飞机的飞行不会偏离航向呢为此，科学家们研究出一种振动陀螺仪。它的主要部件像只音叉，是通过一个中柱固定在基座上的。装在音叉两臂四周的电磁铁使音叉产生固定振幅和频率的振动。当飞机偏离正确航向时，音叉基座和中柱会发生旋转，中柱上的弹性杆就会将这一振动转变成一定的电信号，传给转向舵，于是航向便被纠正了。科学家的这一研究灵感来自苍蝇的翅膀，由振动陀螺仪的工作原理可以推知苍蝇在飞行中保持航向的方法应该是( )。

A．翅膀粗糙的上表面形成空气涡旋，同时产生的一个反作用力使得苍蝇可以平稳升起

B．翅膀关节极有弹性，直接伸人身体并同强有力的肌肉纤维连接，能承受巨大的作用力，并将力量传送到翅膀末端

C．每个翅膀前部的上方都有一块深色的角质加厚区，被称为翼眼或称翅痣，以减少振动

D．后翅以每秒钟330次的频率不停地振动，当苍蝇身体倾斜时后翅振动频率的变化能够被其基部的感受器所感觉，传达给“大脑”
