Since the 1970s, scientists have been searching for ways to link the brain with computers. Brain-computer interface (界面) (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 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.

1. BCI is a technology that can _________________.

A. help to update computer systems

B. link the human brain with computers

C. help the disabled to recover

D. control a person's thoughts

2.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.

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. scalp→cap→computer→wheelchair

D. cap→computer→scalp→wheelchair

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

A. BCI Could Mean More Freedom for the Disabled

For many years, machines have been doing work that people once did， including some difficult jobs. Search and rescue operations in dangerous environments are often seen as the first areas that will employ high technology robots. But there is another area where they may soon take jobs traditionally held by human beings： the restaurant industry.

Teams from around the world competed in early June at the DARPA Robotic Challenge Finals in California. A team from South Korea and its robot called DRC-Hubo，won the first place in the competition. The second and third place winners were from the United States. The robots were required to drive a vehicle, climb up steps and do mechanical work. Such ac­tivities are easy for humans to perform，but more difficult for machines. Not all of the com­petitors were successful. The failures showed how difficuit it is to design effective walking machines.

Akihiro Suzuki works at Yaskawa Electric，a company that develops robots. He says ro­bots cannot do everything a human can，but they are able to work without becoming tired. He says robots cannot taste food，change heating levels or seasonings to get the best flavor (风 味）.But he says if a food can be easily prepared，a robot can repeat the same movement to re­produce the same meal.

One Japanese woman who saw the robots working wanted to bring them home. Masayo Mori says she would like to have a husband who could work like a robot. Suzumo Machinery showed its sushi (寿司）maker robot. It performs the often difficult work of wrapping the popular Japanese food. Hiroshi Monden is an official with the company. He says people all o­ver the world now eat sushi，but there are not enough skilled workers to prepare it. He says his machine can help anyone make sushi.

For some reason Dodger did not want to enter London during daylight, so it was nearly eleven o'clock at night when they got near the centre. Oliver had never seen a dirtier or more miserable place. The streets in this district were narrow and muddy, and there were terrible smells everywhere. Children wandered around even at this time of night, in and out of the many shops, playing and screaming. The pubs were full of people fighting, and big, evil-looking men stood in the doorways or at dark corners. Oliver almost wanted to run away, but just then Dodger pushed open a door and pulled Oliver into a dark hall.

“Who's there?” a voice cried out.

“It's me,” said Dodger. The faint light of a candle appeared in the hall.

“Who's the other one?”

“A new friend.”

They went up some dark and broken stairs. Oliver could hardly see where he was going, but Dodger seemed to know the way, and helped Oliver up. They entered a room with walls that were black with age and dirt. In front of the fire was a table with a candle stuck into a bottle of beer, and an old man, with a horribly ugly face and red hair, stood next to the fire cooking. He was wearing a dirty old coat and seemed to divide his attention between his cooking and a number of silk handkerchiefs, which were hanging near the fire. There were several rough beds in the room. Four or five boys, about the same age as Dodger, sat round the table, smoking and drinking like middle-aged men. They all looked up when Dodger and Oliver entered.

“This is him, Fagin,” Dodger said to the old man. “My friend Oliver Twist.”

Fagin smiled and shook Oliver's hand. Then all the young gentlemen came up to him and shook both his hands very hard, especially the hand which held his few possessions. One of the boys was particularly kind. He even put his hands in Oliver's pockets so that Oliver would not have to empty them himself when he went to bed. The boys would probably have been even more helpful, but Fagin hit them on their heads and shoulders until they left Oliver alone.

“We're very glad to see you, Oliver,” said Fagin. “I see you're staring at the handkerchiefs, my dear. Aren't there a lot? We've just taken them all out to wash them, that's all! Ha! Ha! Ha!”

This seemed to be a joke, as the old gentleman and all his young friends gave loud shouts of laughter. Then supper began. Oliver ate his share of the food and was then given a glass of gin-and-water. Fagin told him to drink it fast. Immediately afterwards, Oliver felt himself lifted onto one of the beds and he sank into a deep sleep.

1.Why did all the young gentlemen come up to Oliver and shake his hands very hard?

A. Because they were of the same age.

B. Because they liked Oliver at the first sight.

C. Because they were required to do so.

D. Because they wanted to steal something from Oliver.

2.Why did Dodger enter London late at night?

A. Because Dodger was too weak to walk until.

B. Because Dodger was afraid of being seen by others.

C. Because Dodger and Oliver wanted to play in the countryside.

D. Because Dodger was afraid of Fagin and did not want to go home.

3.According to the passage, we can infer from the passage that _____.

A. Oliver was killed by a glass of gin-and-water

B. all of them are thieves except Oliver

C. most boys felt pity for Oliver

D. most boys wanted to make friends with Oliver

Shyness equals (等于) losing opportunities, less pleasure and fewer social connections, but there are ways to make it a thing of the past.

When I was fifteen, I was shy. I remember an attractive girl trying to talk with me. My shyness made me focus on me instead of her. I heard my own voice but not hers and I thought about what I was trying to say instead of what she was trying to say.

To overcome shyness you need to learn to relax. This gives you the space to practice certain conversational skills. Relaxed socializing (社交) is so pleasurable. To start reducing your own shyness, I want you to absorb the following tips and ideas and start to put them into practice.

Focus your attention away from yourself. Notice what other people are wearing and make a mental note, listen to their conversation, imagine where they might live, and make a point of remembering names. Not only does this give you more to talk about, it also reduces social anxiety, leaving you feeling calmer.

Ask people open questions. Many people like to talk about themselves and will find you interesting if you find them interesting. Ask questions that require more than a “yes” or “no” response such as “What do you like about this place?’ rather than “Do you like this place?” Once they have answered, you can use add-on (追加) questions connected with the first such as “What other places do you like in this city?” Next you can express your views. This is a great way to get the conversation going.

Now I love meeting new people and suspect that my current social confidence would be unrecognizable to my fifteen-year-old self.
