There comes a point with a technological process when the world wakes up to the possib

ilities of what can be achieved. A decade ago, the cellphone was a bulky item of limited range, high cost and minority interest. Now it is everywhere.

The personal computer (PC) has been around for decades. But it was only in the mid-1990s, with the explosive growth of the Internet and the World Wide Web, that it was first recognized that the technology can be used to do business. It is now fully recognized that shopping in cyberspace, the name given to this world wide electronic network, is the way of the future.

A recent study by the Department of Trade and Industry (the DTI) provides some impressive data. In the United States, the world' s largest consumer of goods， about 21% of the population is now online. Europe is still behind, with only 10% in Britain,for example. But, as we've seen before, when it comes to technology, nothing stays the same for long. The number of people online is rising dramatically throughout the world.

1.According to the passage, how was the cellphone like. a decade ago？

A.It interested few people

B.It cost a lot but was used everywhere

C.It had small size with bad connection

22.People realized that the technology can help do business when

A.the cellphone was everywhere

B.the Internet began to be widely used

C.the personal computer was more and more popular

2.According to the passage, what is the way of the future？

A.Use of personal computers throughout the world

B.Buying or selling via the Internet and the World Wide Web

C.The explosive growth of the Internet and the World Wide Web

3.According to the passage, which of the following statements is NOT true？

A.America consumes more goods than other countries

B.The population online in Britain is smaller than that in the Unites States

C.The number of people online is rising slowly throughout the world

Wide World of Robots

Engineers who build and program robots have fascinating jobs. These researchers tinker(修补) with machines in the lab and write computer software to control these devices. “They’re the best toys out there,” says Howle Choset at Carnegie Mellon University in Pittsburgh. Choset is a roboticist, a person who designs, builds or programs robots.

When Choset was a kid, he was interested in anything that moved — cars, trains, animals. He put motors on Tinkertoy cars to make them move. Later, in high school, he built mobile robots similar to small cars.

Hoping to continue working on robots, he studied computer science in college. But when he got to graduate school at the California Institute of Technology in Pasadena, Choset’s labmates were working on something even cooler than remotely controlled cars: robotic snakes. Some robots can move only forward, backward, left and right. But snakes can twist(扭曲) in many directions and travel over a lot of different types of terrain(地形). “Snakes are far more interesting than the cars,” Choset concluded.

After he started working at Carnegie Mellon, Choset and his colleagues there began developing their own snake robots. Choset’s team programmed robots to perform. the same movements as real snakes, such as sliding and inching forward. The robots also moved in ways that snakes usually don’t, such as rolling. Choset’s snake robots could crawl(爬行) through the grass, swim in a pond and even climb a flagpole.

But Choset wondered if his snakes might be useful for medicine as well. For some heart surgeries, the doctor has to open a patient’s chest, cutting through the breastbone. Recovering from these surgeries can be very painful. What if the doctor could perform. the operation by instead making a small hole in the body and sending in a thin robotic snake？

Choset teamed up with Marco Zenati, a heart surgeon now at Harvard Medical School, to investigate the idea. Zenati practiced using the robot on a plastic model of the chest and they tested the robot in pigs.

A company called Medrobotics in Boston is now adapting the technology to surgeries on people. Even after 15 years of working with his team’s creations, “I still don’t get bored of watching the motion of my robots,” Choset says.

16. Choset began to build robots in high school.

A. Right

B. Wrong

C. Not mentioned

第10题

In 1950 it was predicted that eight or ten electronic computers would be sufficient to han

dle all the scientific and business needs of the United States. Likewise, the chief executive officer of IBM advised the company not to invest time or money in developing computers because he foresaw a limited commercial market. But these predictions were proved totally inaccurate as the computer industry developed into a multibilliondollar business. Today the computer plays a vital role in the lives of many Americans and is seen as one of the greatest technological developments of all times.

Since computers can handle large amount of data rapidly and efficiently, categorize, process, and report information for a variety of business operations, they, in fact, have a virtually unlimited capacity for producing business data. However, computers can't think, their role in business is limited to those areas in which they can process information more efficiently and effectively than human being. At the administrative level, managers decide how computers and humans can be used most effectively to perform. a particular business task.

Computers have become an integral part of day-to-day business transactions as well as analytic tools for long range planning, research, and development. Even a small business can utilize computers by either purchasing a small unit known as a minicomputer, leasing one, or by timesharing. In a timesharing system, each user is regularly scheduled for time to use the computer system. A wide variety of businesses and individuals participate in timesharing computer system.

By performing data processing tasks such as accounting and billing, computers are playing an increasingly important role in businesses. Currently, business are developing overall management information systems in which computers function as essential tools in solving problem and decisionmaking at all administrative levels.

Since 1950s, the computer industry has ______.

A．declined

B．remained about the same

C．increased tremendously

D．increased slightly
