Third-generation mobile phones, known as 3G, are the next big step for the telecom(电信) industry. Data speed in 3G networks is much quicker than that in present technology. This means users can have high-speed Internet access(上网) and enjoy video and CD-quality music on their phones.
"Mobile data is not a dream; it's not an option(选择) but a requirement" said Len Lauer, head of a US communications company, Sprint PCS, at a 3G conference in Bangkok earlier this month.
With 3G, you can forget about text messages telling you yesterday's news; a 3G phone can receive video news programs, updated(更新) four times a day. Internet access will also be much quicker, making it easier to surf the Web on your phone than on your computer at home.
Don't worry about getting lost. 3G phones offer map services so you can find a new restaurant just by pressing a few keys on your handset(手持机).
However, the most impressive part of 3G technology is video calling. With live two-way video communication, you can have face-to-face talks with friends and family on your mobile phone.
Many European countries have already launched the service. In May 2000 the US Government issued five licenses(许可证) to run 3G wireless services, while the first 3G phones arrived in Italy in March this year.
International telecom companies can't wait to sell 3G in China, the world's largest mobile telecommunications market. But they will have to be patient. At the moment, China is busy testing its 3G-based technologies, networks and services. This will be followed by a trial period before the phones can finally hit the shops.
“We need to create a pool of 3G customers before the large-scale commercial launch(开始) of the service,” said Fan Yunjun, marketing manager for Beijing Mobile. “We expect that the 3G licenses will be issued(发行) late next year.”
We'll also see 3G services enter our daily lives in all-sorts of new ways, from shopping and banking to playing interactive computer games over the net. It won't be long before we think nothing of sitting on a train using a mobile palmtop(掌上型电脑) to check our bank accounts or pay bills. You might even click on an icon(图标) on the screen to set up an immediate video-conference with your bank clerk.

Among the most popular books being written today are those which are usually classified as science fiction. Hundreds of titles are published every year and are read by all kinds of people. Furthermore, some of the most successful films of recent years have been based on science fiction stories.
It is often thought that science fiction is a fairly new development in literature, but its ancestors can be found in books written hundreds of years ago. These books were often concerned with the presentation of some form of ideal society, a theme which is still often found in modern stories.
Most of the classics of science fiction, however, have been written within the last one hundred years. Books by writers such as Jules Verne and H. G. Wells, to mention just two well-known authors, have been translated in many languages. Modern science fiction writers don't write about men from Mars or space adventure stories. They are more interested in predicting the results of technical developments on society and the human mind, or in imagining future worlds which are a reflection of the world which we live in now. Because of this their writing has obvious political undertones.
In an age where science fact frequently over-takes science fiction, the writers may find it difficult to keep ahead of scientific advances. Those who are sufficiently clear-sighted to see the way we are going, however, may provide a valuable lesson on how to deal with the problems which society will inevitably face as it tries to master its new technology and come to terms with a continually changing view of the world. Most of the classics of science fiction have been written within __________.
| A．the last few hundred years |
| B．the last one hundred years |
| C．the last two hundred years |
| D．the last three hundred years |
Modern science fiction writers are interested in __________
| A．writing about men from Mars |
| B．writing about everything but politics |
| C．forecasting the results of technical develop-ments and imagining the future world |
| D．writing space adventure stories |
Science fiction writers may provide a valuable les-son on how to deal with the problems of __________
| A．conflict used by different political theories |
| B．adopting new technology and adapting quickly to its effects on society |
| C．conflict caused by different religious beliefs |
| D．space adventure |

An underwater robot that can hear the calls of whales, and to help ships to avoid them, has just been successfully tested in the Bahamas.
The scheme relies on a fish-shaped glider that moves freely through the ocean. It can dive down as far as 200 meters below the surface and direct itself by shifting a weight from fore to aft. A microphone attached to the bottom of the glider can pick up calls from all whales, including the high frequency call of the beaked whale, which until now has been difficult to detect. The glider returns periodically to the surface to radio its data back to base, or if that's too far away, it can call a satellite phone and send its information anywhere in the world.
"We are entering a new era of underwater sensing' says Jim Theriault of Defence Research and Development Canada, in Dartmouth, Nova Scotia who ran the trial. "We can put a glider in the Bahamas and monitor it in Nova Scotia. ”
The hope is that naval or other ocean-going operations that use sonar (声呐）will be able to more easily track where whales are, and so avoid using their noisy equipment when they are close by. There is circumstantial evidence that sonar can upset whales and a number of strandings (搁浅）have been seen shortly after naval sonar operations. “We're trying to lower the potential risk by knowing the animals are there，” says Theriault. The shape of the underwater robot is like __________
| A．a man |
| B．a fish |
| C．a snake |
| D．a turtle |
The underwater robot is built to __________.
| A．help whales move to the Bahamas |

To radio its data back to base, the robot has to __________
| A．dive down as far as 200 meters below the surface |
| B．stay deep in the water |

Scientists are racing to build the world's first thinking robot. This is not science fiction： some say they will have made it by the year 2020，Carol Packer reports.
Machines that walk, speak and feel are no longer science fiction. Kismet is the name of an android (人形机器人）which scientists have built at the Massa-chusetts Institute of Technology (MIT). Kismet is different from the traditional robot because it can show human emotions. Its eyes, ears and lips move to show when it feels happy, sad or bored. Kismet is one of the first of a new generation of androids—robots that look like human beings—which can imitate human feelings. Cog, another android invented by the MIT, imitates the action of a mother. However, scientists admit that so far Cog has the mental ability of a two-year-old.
The optimists (乐观主义者） say that by the year2020 we will have created humanoids (人形机器人） with brains similar to those of all adult human beings. These robots will be designed to look like people to make them more attractive and easier to sell to the public. What kind of jobs will they do? In the future, robots like Robonaut , a humanoid invented by NASA, will be doing dangerous jobs, like repairing space stations. They will also be doing more and more of the household work for us. In Japan, scientists are designing androids that will entertain us by dancing and playing the piano.
Some people worry about what the future holds：Will robots become monsters(怪物）？ Will people themselves become increasingly like robots? Experts predict that more and more people will be wearing micro-computers，connected to the Internet, in the future. People will have micro-chips in various parts of their body, which will connect them to a wide variety of gadgets (小装置）. Perhaps we should not exaggerate (夸大）the importance of technology, but one wonders whether, in years to come，we will still be falling in love, and whether we will still feel pain. Who knows? Kismet is different from traditional robots because __________.
| A．it thinks for itself |
| B．it is not like science fiction |
| C．it can look after two-year-old children |
| D．it seems to have human feelings |
What makes Cog special?
| A．It looks like a mother. |
| B．It behaves like a child. |
| C．It can imitate the behavior of a mother. |
| D．It has a huge brain. |
In about 10 years' time from now, robots __________
| A．will become space designers |
| B．will look like monsters |
| C．will behave like animals |
| D．will think like humans |
In the future robots will also __________.
| A．explore space |
| B．entertain people |
| C．move much faster |
| D．do all of the housework |
What is the writer's attitude to robots in the future?
| A．Critical. |
| B．Hostile. |
| C．Objective. |
| D．Enthusiastic. |
