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 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. 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 guarantee that they can use the technology over long periods of time.
1.BCI is a technology that can ________.
A. help the disabled to recover
B. control a person's thoughts
C. help to update computer systems
D. link the human brain with computers
2.How did Tavella operate the wheelchair in the laboratory?
A. By talking to the machine.
B. By controlling his muscles.
C. By using his mind.
D. By moving his hand.
3.Which of the following would be the best title for the text?
A. Robotic Vehicles Could Help to Cure Brain Injuries
B. BCI Could Mean More Freedom for the Disabled
C. New Findings About How the Human Brain Works
D. Switzerland, the BCI Research Center

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 orders to machines.
Recently, two researchers, Jose Millan and Michele Tavella from the Federal Polytechnic School in Lausanne, Switzerland, showed 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 wheelchair and guided it with his thoughts.
“Our brain has billions of nerve cells(神经细胞). These send signals through the spinal cord (脊髓)to the muscles(肌肉) 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 outside world and also to control the machine.”
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 understands the signals and directs the motorized wheelchair. The wheelchair also has two cameras that recognize objects in its path. They help the computer react to orders from the brain.
Prof. Millan, the team leader, says scientists keep improving the computer software that understands brain signals and turns them into simple orders. “The practical possibilities that BCI technology offers to disabled people can be divided into two kinds: communication, and controlling the machine.

For years scientists have been worried about the effects of air pollution on the earth’s natural conditions.Some believe the air inside many houses may be more dangerous than the air outside.It may be one hundred times worse.
Indoor air pollution can cause a person to feel tired,to suffer eye pain,headache and other problems.Some pollutants(污染物质) can cause breathing disorders,diseases of blood and even cancer.Most scientists agree that every modern house has some kind of indoor pollution.
People have paid more attention to the problem now.It is said that when builders began making houses and offices,they did not waste energy.To do this they built buildings that limited the flow of air between inside and outside.They also began using man-made building materials.These materials are now known to let out harmful gases.
As the problem became more serious,scientists began searching for a way to deal with it.They discovered a natural pollution control system for buildinggreen plants.Scientists do not really know how plants control air pollution.They believe that a plant’s leaves absorb(吸收;吸引) or take in the pollutants.In exchange the plant lets out oxygen through its leaves and small organizations on its roots.Scientists suggest that all buildings should have one large plant or several small plants inside for every nine square meters of space.Studies of different plants show that each absorbs different chemicals.So the most effective(有效的) way to clean the air is to use different kinds of plants.Having green plants inside your house can make it prettier and more healthy place.
1.Generally speaking,indoor air pollution may be more harmful than that outside because _______.
A. indoor air pollution can often make people seriously ill
B. man-made building materials give off dangerous gases
C. there may be more harmful gases outside the buildings
D. the flow of air indoors is limited,which is very harmful
2.Some kind of indoor pollution can be found in _______.
A. every modern house B. every old house
C. all kinds of houses D. all kinds of offices
3.The indoor air pollution is caused by _______.
A. the limit of the flow of air between inside and outside
B. the building way that the builders want to save energy
C. the building things that are made of man-made materials
D. the man-made building materials and the limit of air-flow
4.The reason why we should use different kinds of plants to clean the air is that _______.
A. plants can let out all kinds of pollutants indoors
B. plants may take in more oxygen which people need
C. plants can absorb some kinds of harmful indoor chemicals
D. plants can make our houses prettier and more healthy
