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 (頭皮) 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

The United States government wants to know what the public thinks about its findings on the safety of cloned animals.
The Food and Drug Administration says meat and milk from clones of adult cattle,pigs and goats are safe to eat. An F. D. A. official called them "as safe to eat as the food we eat every day. " And when those clones reproduce sexually,the agency says,their offspring (后代) are safe to eat as well. But research on cloned sheep is limited. So the F. D. A. proposes that sheep clones not be used for human food.
The United States this year could become the first country to approve the sale of foods from cloned animals. First,however,the public will have ninety days to comment on three proposed documents. On December 28th the F. D. A. released a long report,called a draft risk assess?ment,along with two policy documents.
The agency says it must receive comments by April second. The F. D. A. seemed ready to act several years ago,but an advisory committee called for more research.
For now,the government will continue to ask producers to honor a request that they not sell foods from cloned animals.
Clones are still rare. They cost a lot and are difficult to produce.
The F. D. A. says most food from cloning is expected to come not from clones themselves,but from their sexually reproduced offspring. It says clones are expected to be used mostly as breeding animals to spread good qualities.
Public opinion studies show most Americans do not like the idea of food from cloned ani?mals. But this research also shows the public knows little about cloning.
Cloning differs from genetic engineering. A cell taken from a socalled donor animals is grown into an embryo (胚胎) in the laboratory. Next,the embryo is placed into the uterus (子宮) of a female animal. If the process is successful,the pregnancy reaches full term and a genetic copy of the donor animal is born.
( ) 1. From the passage we know that .
A. foods from cloned animals are popular in America
B. cloned adult animals are safe to eat except sheep
C. cloned animals will be easy to produce
D. most foods from cloning are expected to take place of other foods
( ) 2. The main purpose of the text is to .
A. tell an interesting story B. give some advice on foods
C. give a report D. compare different opinions
( ) 3. Who believes that foods from cloning are safe to eat?
A. Most Americans. B. An advisory committee.
C. Critics. D. The F. D. A.
( ) 4. It can be inferred from the last paragraph that .
A. cloning has much in common with genetic
B. not every cell taken from a donor animal can grow into a genetic copy
C. the donor animal should be a female one
D. cloned animals grow faster than normal ones
