Since the 1970s,scientists have been searching for ways to link the brain with computers. Braincomputer interface (BCD 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 by a person's thoughts.
"Our brain has billions of nerve cells. They 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 pre?vent 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 re?ceives brain signals and turns them into simple commands. "The practical possibilities that BCI technology offers to disabled people can be grouped into two categories,communication and controlling devices. One example is this wheelchair."
He says his team 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 technolo?gy over long periods of time.
( ) 5. BCI is a technology that can .
A. help to update computer systems B. link the human brain with computer
C. help the disabled to recover D. control a person's thoughts
( ) 6. 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.
( ) 7. Which of the following shows the path of the signals described in Paragraph 4?
A. scalp—computer—cap—wheelchair B. computer—cap—scalp—wheelchair
C. scalp—cap—computer—wheelchair D. cap—computer—scalp—wheelchair
( ) 8. 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
( ) 9. Which of the following would be the best title for the test?
A. Switzerland,the BCI Research Center
B. New Findings about How the Brain Works
C. BCI Could Mean More Freedom for the Disabled
D. Robotic Vehicles Could Help to Cure Brain Injuries

Astronauts' meals have come a long way from the freezedried powders and semiliquid pastes of decades ago：now US scientists want to grow vegetables in minigreenhouses on the moon.
Scientists say they are looking forward to a time when residents of future lunar or even Mar?tian outposts will be able to dine on fresh vegetables. Paragon Space Development Corporation has unveiled what it called the first step toward growing flowers―and eventually food―on the moon.
Paragon,which has partnered with NASA in previous experiments on the Space Shuttle and the International Space Station,calls it a "Lunar Oasis".
This is a sealed greenhouse that looks like a bell jar encased in a 46 cm triangular aluminum frame. It is designed to safely land a laboratory plant on the lunar surface,and protect it while it grows.
The miniature greenhouse is to be launched into space by Odyssey Moon Ltd.，a participant in the Google Lunar X Prize. This competition offers $ 20 million to any entrant who can launch,land and operate a rover on the lunar surface.
Paragon officials say future testing of the " Lunar Oasis" will be driven by Odyssey's flight schedule,which will not happen until 2012 at the earliest.
When it does lift off the greenhouse will contain the seeds of Brassica,a hardy plant related to Brussels sprouts and cabbage. Because Brassica goes from seed to flower in just 14 days,it can complete its life cycle in a single lunar night.
"Colonizing the Moon or Mars seems so far away,but it is important that we do this re?search now," Paragon president Jane Poynter said.
"It takes a long time to get a lot of research,and to get integrated,reliable efficient sys?tems before colonists move in ," she said.
( ) 5. What can we know from the text?
A. American astronauts have eaten fresh vegetables on the moon:
B. Astronauts' meals have been the freezedried powers and semiliquid pastes so far.
C. The sealed greenhouse looks like a semicircle jar.
D. It won't take long before colonists move in to get a lot of research.
( ) 6. The article implies that .
A. astronauts can grow flowers in space at present
B. Paragon and NASA will carry out the test separately
C. Lunar Oasis is a series of experiments carried out in space
D. the earliest testing of the Lunar Oasis may be in 2012
( ) 7. The underlined word "colonists" in the last paragraph probably has the meaning of
A. plants B. wild beasts C. human beings D. scientists
( ) 8. The seeds of Brassica will be contained in the greenhouse mainly because .
A. their life cycle is much shorter
B. they are more nutritious than other food
C. they are related to Brussels sprouts and cabbage
D. they are very delicious

Something roared like thunder. The earth shook a little and we heard the rat-a-tattat of gunfire. "Father!" Hassan cried. We sprung to our feet and raced out of the living room.
"Father!What's that sound?" Hassan screamed,his hands outstretched toward Ali. Ali wrapped his arms around us. A white light flashed and lit the sky in silver. It flashed again and was followed by rapid sharp sounds of gunfire.
"They're hunting ducks, ”Ali said in a hoarse voice. "They hunt ducks at night,you know. Don't be afraid."
A siren (警报声) went off in the distance. Somewhere glass broke and someone shouted. I heard people on the street,awakened from sleep. Hassan was crying. Ali pulled him close and held him with tenderness.
We stayed huddled (蜷缩) that way until the early hours of the morning. The shootings and explosions had lasted less than an hour,but they had frightened us badly,because none of us had ever heard gunshots in the streets. They were foreign sounds to us then. The generations of Afghan children whose ears would know nothing but the sounds of the bombs and gunfire were not yet born. Huddled together in the dining room and waiting for the sun to rise,none of us had any idea that a way of life had ended. The end came when Russian tanks were rolling into the very same streets where Hassan and I played,bringing the death of the Afghanistan I knew and marking the start of a still ongoing era of bloodletting.
Just before the sunrise,Baba's car pulled into the driveway. His door slammed shut and his running footsteps pounded the stairs. Then he appeared in the doorway and I saw something on his face. Something I didn't recognize right away because I'd never seen it before：fear. "Amir!Hassan！" He cried as he ran to us,opening his arms wide. "They blocked all the roads and the telephone didn't work. I was so worried！"
We let him wrap us in his arms and,for a brief moment,I was glad about whatever had happened that night.
( ) 1. Who is the author of this passage?
