Mark and his brother Jason both were looking at the shining new computer enviously. Jason was determined not to go against their father’s wishes but Mark was more adventurous than his brother. He loves experimenting and his aim was to become a scientist like his father.
“Dad will be really mad if he finds out you’ve been playing with his new computer” Jason said, “He told us not to touch it.”
“He won’t find out,” Mark said, “I’ll just have a quick look and shut it down.”
Mark had been scolded before for touching his father’s equipment. But his curiosity was difficult to control and this new computer really puzzled him.
It was a strange-looking machine — one his dad had brought home from the laboratory where he worked. “It’s an experimental model,” his father had explained, so don’t touch it under any circumstances.” But his father’s warning only served to make Mark more curious. Without any further thought, Mark turned on the power switch. The computer burst into life and seconds later, the screen turned into colours, shifting and changing, and then two big white words appeared in the centre of the screen: “SPACE TRANSPORTER.”
“Yes!” Mark cried excitedly, “It’s a computer game. I knew it! Dad’s only been pretending to work. He’s really been playing games instead!” A new message appeared on the screen:
“ENTER NAMES
VOYAGE　１
VOYAGE　２
Mark’s finger flew across the keyboard as he typed in both of their names.
“INPUT ACCEPTED.
START  TRANSPORT  PROGRAM.
AUTO-RETRIEVE  INITIATED(自动回收程序已启动).”
The screen turn even brighter and a noise suddenly rose in volume.
“I think we’d better shut it off, Mark,” Jason yelled out in terror, reaching for the power switch. A beam(光束) of dazzling white light burst out of the computer screen, wrapping the boys in its glow(光芒)，until they themselves seemed to be glowing. Then it died down just as suddenly as it had burst into life. And the boys were no longer there. On the screen, the letters changed：
“TRANSPORT SUCCESSFUL．
DESTINATION:  MARS.
RETRIEVE DATE:  2025
【小题1】Why did Mark touch the computer against his father’s warning?

But his hand never reached the switch. A single beam of dazzling white light burst out of the computer screen, wrapping the boys in its glow (光芒), until they themselves seemed to be glowing. Then it died down just as suddenly as it had burst into life. And the boys were no longer there. On the screen, the letters changed.

【小题1】Why did Mark touch the computer against his father’s warning?

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 Millan 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. Millan, 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 make sure that they can use the technology over long periods of time.
