Some of the computer experiments now going inspire imagination of the future. For example, scientists are working in devices that can electronically perform. some sight and hearing functions, which could make easier for the blind and deaf. They are also working on artificial arms and legs that respond to the electric impulses (脉冲) produced by the human brain. Scientists hope that someday a person who has lost an arm could still have near-normal brain control over an artificial arm.
Video games, computerized effects in movies, and real-life training machines now being used by the U. S. Army are causing some people to predict new educational uses for computers. Computers could someday be used to imitate travel to other planets, to explore the ocean floor or to look inside an atom.
Experiment with electronic banking and shopping inspire predictions that these activities will soon be done from home computer terminals (终端) . Cars, too, might be equipped with computers to help drivers find their way around or to communicate with home and office computers.
Many people, including handicapped (残废的) workers with limited ability to move around, already are working at home using computer terminals. Each terminal is connected to a system at a company's main office. Some futurists say the day may come when few people will have to leave home to go to work—they'll just turn on a terminal.
Which of the following would be the most appropriate title for the passage？
A．Futurists and Computers
B．A Look at Future Uses of Computers
C．Computer Experiments
D．Scientists and Computers
Some of the computer experiments now going on inspire exciting visions of the future. For example, scientists are working on devices that can electronically perform. some sight and hearing functions, which could make life easier for the blind and deaf. They're also working on artificial arms and legs that respond to the electric impulses produced by the human brain. Scientists hope that some day a person who's lost an arm could still have near-normal brain control over an artificial arm.
Video games, computerized special effects in movies, and real-life training machines now being used by the US Army are causing some people to predict new educational uses for computers. Computers could some day be used to simulate travel to other planets, to explore the ocean floor, or to look inside an atom.
Experiments with electronic banking and shopping inspire predictions that these activities will soon be done from home computer terminals. Cars, too, might be equipped with computers to help drivers find their way around (Honda has one in an experimental car) or to communicate with home and office computers. Many people, including handicapped workers with limited ability to move around, already are working at home using computer terminals. Each terminal is connected to a system at a company's main office. Some futurists say the day may come when few people will have to leave home to go to work -- they'll just turn on a terminal
A growing number of factories such as the General Motors Plant in Newark, Delaware, "hire" computerized robots to perform. tasks such as spot welding. Some executives get a gleam in their eyes as they envision the spread of these "perfect workers" -- no coffee breaks, no strikes, and no vacations or sick days.
These modern and potential computer uses are possible because of the silicon microchip.
These chips, which have become increasingly complex since their beginning in 1959, contain a network of information pathways. Electronic impulses travel along the paths. The plans for a chip look much like a city street plan and can be as large as a football field. It can take as long as three months to complete a new chip design. Chips are used to store information, too. An entire "computer" can be put onto one chip -- called a microprocessor.
As chips become even more complex, easier to make, and less costly, futurists predict limitless possibilities. A group of Japanese scientists is working on a new generation of computers, which they hope will be able to understand vocal instructions, talk back to their users, and automatically try out alternate solutions to a problem to come up with the best answer.
Some people say that the humans of the future will never be without their companion -- computers. Predicting the future can be tricky, of course. In 1948 an IBM study predicted that there would never be enough demand for computers to justify going into the business!
What is the purpose of the passage？
A．To tell the readers what computers will look like in the future.
B．To show the close relations between man and computers.
C．To tell the readers how important silicon microchips are.
D．To talk about the possible future uses of computers.

C.All authorised employees must swipe an officially issued, personal identity card at the entrance to the department before they can gain access
D.All hard copies of confidential information must be shredded at the end of each day or locked overnight in a safe if needed again
West lake College in Virginia will start a laptop computer program that allows students to do school work anywhere they want. Within five years,each of the 1,500 students at the college will receive a laptop. The laptops are a part of a $10 million computer program at West lake, a 110-year-old college. The students with laptops will also have access to the Internet. In addition, they will be able to use e-mail to “speak”with their teachers, their classmates, and their families. However, the most important part of the laptop program is that students will be able to use computers without going to computer labs. They can work with it at home, in a fast-food restaurant or under the trees-anywhere at all!
Because of the many changes in computer technology, laptop use in higher education, such as colleges and universities, is workable. As laptops become more powerful, they become more similar to desktop computers. In addition, the portable computers can connect students to not only Internet, but also libraries and other resources. State higher-education officials are studying how laptops can help students.
State Officials also are testing laptop programs at other universities,too.
At West lake College, more than 60 percent of the staff use the computers. The laptops will allow all teachers to use computers in their lessons. As one West lake teacher said, “Here we are in the middle of Virginia and we’re giving students a window on the world. They can see everything and do everything.”
1.The main purpose of the laptop program is to give each student a laptop to ____.
A、access the Internet
B、work at home

When computer servers operate a complex program, they can get very hot. Cooling the servers can be costly. So researchers asked what would happen if the heat created by the servers could be captured and used？
Data centers of large Internet companies such as Google and Microsoft have thousands of computer servers. As these servers process information, they create large amounts of heat, so they need huge cooling systems. These systems send the heat into the air. The Dutch company Nerdalize thinks paying for electricity to operate the servers and then paying again to cool them is a waste of energy. So it developed a device called the e-Radiator. It is a computer server that also works as a heating source. Boaz Leupe is the chief executive officer of Nerdalize. He says the e-Radiator saves money because companies don't have to pay to cool their servers.
"The kilowatt(千瓦)hour you are using is used twice -- once to heat the home and once to compute the client's task without the cooling overhead." He says five homeowners in the Netherlands are testing the heating device in their homes. "We reimburse the electricity the server uses, and that we can do because of the computer clients on the other side, and, in that way, homeowners actually get heating for free, and computer users don't have to pay for the overhead of the data center.
Jan Visser is one of the participants in the year-long experiment. He says the amount of heat produced by the e-Radiator depends on the work being done by the computer server. He says it cannot be used as the primary source of heat. But he is ready to try it.
He says if it provides enough warmth, he will be able to use his home's heating system less, which will save him money. Nerdalize says e-Radiators create heat temperatures of up to 55℃. It says the devices could save users up to $440 in heating costs a year.

"State of the art" is something that is as modem as possible. It is a product that is based on the very latest methods and technology. Something that is "state of the art" is the newest possible design or product of a business or industry. A state of the art television set, for example, uses the modernest electronic design and parts. It is the best that one can buy.
"State of the art" is not a new expression. Engineers have used it for years, to describe the best and most modem way of doing something. Millions of Americans began to use the expression in the late 1970 ' s. The reason was the computer revolution. Every computer company claimed that its computers were "state of the art".
Computer technology changed so fast that a state of the art computer today might be old tomorrow. (80) The expression "state of the art" became as common and popular as computers themselves. Now all kinds of products are said to be "state of the art".
