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.”
2.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
1.Which of the following is TRUE accnternet connections have been popular everywhere.
B．Internet service providers are willing to care about rural customers.
Some companies have delivered the Internet over standard power lines.Advancements in cheaper and more efficient fiberoptic cables(光缆)promise to bring extremely fast Internet connections to more users.Still, the “last mile” problem remains hard to deal with.There will always be somewhere that doesn't have an affordable broadband connection. But someday that might not matter. If the rapid progress in cellphone technology has any indication, it may not be too long before an Internet connection simply follows you wherever you go.
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.”
C．The problem of Internet access hasn't been completely dealt with.
D．Computers can't become popular in developing countries.
2.Paragraph 4 mainly tells us that technological advancements ________.
A．make TV and telephone available everywhere
B．bring great change to people's everyday life
C．bring faster Internet connections to users
D．make it possible for more people to use the Internet
1.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.
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.
Technology experts often talk about the “last mile” problem, which refers to the difficulty of bringing Internet access to remote locations. In cities and suburbs(郊区), it's relatively easy to provide access for everyone. It is much more difficult to deliver access to those living far from cities，especially in developing countries. Internet service providers，for their part，have been reluctant to provide access to sparsely (稀疏地) populated areas. The handful of Internet users they would reach wouldn't cover the expense.
But every year，technological advancements allow of more and more Internet users.Most broadband connections today run over existing cable TV and telephone lines although these technologies aren't available everywhere.
C．Progress in Internet Connections
D．Internet Connections Today

Since the 1970s, scientists have been searching for ways to link the brain with computers.Braincomputer interface (BCI) technology could help people with disabilities send commands to machines.
D．More and more Internet users.
4.The best title for this passage may be “________”．
A．Internet Connection Problems
B．Internet Connections Need Improving
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.
3.What may eventually settle the “last mile” problem?
A．The broadband connection's getting faster.
B．The rapid progress in cellphone technology.
C．More and more Internet connections.

In a computer age, a broadband Internet connection is very popular now.Whether cable or mobile broadband, today's connections are many times faster than those in the early days.Videos play smoothly, complex websites load quickly, and files download much faster than ten years ago. And the files are much bigger too.
There's a hidden problem：you have to live near enough to a major city to get broadband Internet. If you don't, it's slow dialup access for you. And for those living really far away，there may be no Internet access at all.
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.
“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.”
