Wherever you went in the large hall, people were talking about the same thing. The PT/ Wireless and Networks Comm. China（中国国际通信设备技术博览会）held in Beijing last year was the biggest telecom exhibition in Asia．There were 400 representatives from 21 countries. But everyone was speaking the language of technology and there was only one word on their lips-3G.
Third-generation mobile phones, known as 3G, are the next big step for the telecom industry Data speeds in 3G networks are much quicker than present technology. This means users can have high-speed Internet access and enjoy video and CD-quality music on their phones.
“Mobile data is not a dream; it’s not an option—it’s a requirement,” said Len Lauer, head of 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 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.
Face-to-face video calls
And 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.
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 UK Government awarded five licenses to run 3G wireless services, while the first 3G phones arrived in Italy four years later.
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 phase before the phones can finally hit the shops.
“We need to create a pool of 3G customers before the large-scale commercial launch of the service,”said Fan Yunjun, marketing manager for Beijing Mobile.“We expect that the 3G licenses will be given out late next year.”

When Paul was a boy growing up in Utah, he happened to live near a copper smelter（炼铜厂），and the chemicals that poured out had made a wasteland out of what used to be a beautiful forest．One day a young visitor looked at this wasteland and called it an awful area．Paul knocked him down．From then on, something happened inside him.
Years later Paul was back in the area, and he went to the smelter office．He asked if they had any plans or if they would let him try to bring the trees back．The answer from that big industry was “No”.
Paul then went to college to study the science of plants．Unfortunately, his teachers said there weren't any birds or squirrels to spread the seeds．It would be a waste of his life to try to do it．Everyone knew that, he was told．Even if he was knowledgeable as he had expected, he wouldn’t get his idea accepted．
Paul later got married and had some kids．But his dream would not die．And then one night he did what he could with what he had．As Samuel Johnson wrote, “It is common to overlook what is near by keeping the eye fixed on something remote．Attainable good is often ignored by minds busied in wide ranges.” Under the cover of darkness, he went secretly into the wasteland and started planting.
And every week, he made his secret journey into the wasteland and planted trees and grass．For fifteen years he did this against the plain common sense．Slowly rabbits appeared．Later, as there was legal pressure to clean up the environment, the company actually hired Paul to do what he was already doing.
Now the place is fourteen thousand acres of trees and grass and bushes, and Paul has received almost every environmental award Utah has．It took him until his hair turned white, but he managed to keep that impossible vow he made to himself as a child.
When Paul was a boy，______________.
A．he had decided never to leave his hometown
B．the economy of Utah depended wholly on the copper smelter
C．no laws were made to protect the environment against pollution
D．he had determined to stop the copper smelter polluting the area

A．Because he wanted to find out the best way to save the area himself.
B．Because he was interested in planting trees since he was young.
C．Because he wanted to get more knowledgeable people to help him.
D．Because he thought his knowledge would make his advice more persuasive.
What does the underlined phrase “the plain common sense” probably refer to?
A．That it was impossible for trees to grow on the wasteland.
B．That his normal work and life would be greatly affected.
C．That no one would like to join him in the efforts.
