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.

1.BCI is a technology that can________.

A. help to make computer systems more modern

D. cap→computer→scalp→wheelchair

3.The team will test with real patients to_________.

A. make money from them

B. prove the technology useful to them

4.Which of the following would be the best title for the text?

A. Switzerland, the BCI research Center

Once there was a forest where all the animals lived happily together. One day a family went to spend the day in the forest, and the son left his socks there. After the family left, a bear came by, found the socks, and decided to try them on. They fit so well, and he liked them so much that he wouldn't take them off.

All the animals talked about the bear's new look. Soon, in that forest, there began appearing squirrels in shirts, rabbits in shoes, and even rats (老鼠) wearing hats! The forest doctor shook his head, telling animals, "This can't be good. Animals don't need clothes!" But no one listened to him. They said he was just out of fashion.

However, it wasn't long before the first results of fashion-fever came. Several times the squirrel caught his shirt on trees, stopping him in mid-jump and sending him falling to the ground from a tree. The rat couldn't go into his hole without taking off his hat first. Even the bear, because of his socks, slipped（滑到） from the river rock and almost killed himself.

When the animals came to see the doctor, he gave them all the same advice, "Take off those clothes before one day they're going to kill you." Those who listened to the doctor's advice stopped having accidents. And the animals realized that they didn't need clothes at all. Starting to wear them had been very dangerous, and they had only done it to make others admire them, and to get attention.
