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 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 band. 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. 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.

2.How" did Tavella operate the wheelchair in the laboratory?
A. By controlling his muscles.
B. By talking to the machine.

A. scalp→computer→cap→wheelchair
B. computer→cap→scalp→wheelchair
C. scalp→cap→computer→wheelchair
D. cap→computer→scalp→wheelchair
4. 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
5.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

Mr. Johnson, aged twenty-three, battled for half an hour to escape from his trapped car yesterday when it landed upside down in three feet of water. Mr. Johnson took the only escape route—through the boot (行李箱).
Mr. Johnson’s car had finished up in a ditch (沟渠) at Romney Marsin, Kent after skidding on ice and hitting a bank. “Fortunately, the water began to come in only slowly,” Mr. Johnson said, “I couldn’t force the doors because they were jammed against the walls of the ditch and dared not open the windows because I knew water would come flooding in.”
Mr. Johnson, a sweet salesman of Sitting Home, Kent, first tried to attract the attention of other motorists by sounding the horn and hammering on the roof and boot (汽车行李箱). Then he began his struggle to escape.
Later he said, “It was really a half penny that saved my life. It was the only coin I had in my pocket and I used it to unscrew(拧开…的螺丝) the back seat to get into the boot. I hammered desperately with a hammer trying to make someone hear, but no help came.”
It took ten minutes to unscrew the seat, and a further five minutes to clear the sweet samples from the boot. Then Mr. Johnson found a wrench(扳钳) and began to work on the boot lock. Fifteen minutes passed by. “It was the only chance I had. Finally it gave, but as soon as I moved the boot lid, the water and mud poured in. I forced the lid down into the mud and scrambled (move with difficulty) as the car filled up.”
His hands and arms were cut and bruised (擦伤). Mr. Johnson got to Beckett Farm nearby, where he was looked after by the farmer’s wife, Mrs. Lucy Bates. Huddled in a blanket, he said, “The thirty minutes seemed like hours.” Only the tips of the car wheels were visible(can be seen), police said last night. The vehicle had sunk into two feet of mud at the bottom of the ditch.

Good health is the most valuable thing a person can have, but one cannot take good health for granted. It is important to remember that the body needs proper care in order to be healthy. There are three things that a person can do to help stay in good shape: eat right food, get enough sleep, and exercise regularly.
Proper nutrition is important for good health. Your body cannot work well unless it receives the proper kind of “fuel”(燃料).Don't eat too much food with lots of sugar and fat. Eat plenty of foods high in protein, like meat, fish, eggs and nuts. Vegetables and fruits are very important because they provide necessary vitamins and minerals. However, don't overeat. It is not helpful to be overweight.
Getting the proper amount of sleep is also important. If you don't get enough sleep, you feel tired and easily get angry. You have no energy. Over a long period of time a little amount of sleep may even result in a change of personality .Be sure to allow yourself from seven to nine hours of sleep each night. If you do, your body will feel strong and refreshed, and your mind will be sharp.
Finally, get plenty of exercise. Exercise firms the body, strengthens the muscles, and prevents you from gaining weight. It also improves your heart and lungs. If you follow a regular exercise program, you will probably increase your life-span (寿命).Any kind of exercise is good. Most sports are excellent for keeping the body in good shapes: basketball, swimming, bicycling, running and so on are good examples. Sports are not only good for your body, but they are enjoyable and interesting, too.
If everybody were to eat the right foods, get plenty of sleep and exercise regularly, the world would be a happier and healthier place. We would all live to be much older and wiser.
