5、Third-generation mobile phones, known as 3G, are the next big step for the telecom industry. Data speed in 3G networks is much quicker than that in 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 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 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.
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 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 of the service,” said Fan Yunjun, marketing manager for Beijing Mobile. “We expect that the 3G licenses will be issued late next year.”
We'll also see 3G services enter our day-to-clay 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 to check our bank accounts or pay bills. You might even click on an icon on the screen to set up an instant video-conference with your bank clerk.

4、Small discoveries in Indonesia are causing a stir in the science world. Researchers have unearthed(挖掘) tiny bones that they believe belong to an entire new human species. If that's true, it will change how we think about our ancestors.
Clues that the little people may have lived long ago were first revealed last year in the scientific journal Nature. Scientists said that they had found the bones of a three-foot-tall female on the island of Flores, in Indonesia. When they looked more closely, they saw that the nearly complete skeleton(骨骼) belonged to a full-grown adult Researchers named her Hobbit, after the tiny heroes of the Lord of the Rings books.
Now the team is saying it has unearthed even more pieces of the puzzle, including a jawbone and parts of arms, legs and hands from several individuals, as well as stone tools. They reported their find in Nature this month. “The new evidence makes it very clear that these people are a new species, distinct from modern humans,” Peter Brown, a scientist on the team, said．They named these ancient humans Homo floresiensis.
Brown says that these little people lived as recently as 12,000 years ago. If Homo floresiensis was a different species from modern humans, that would make our family tree bigger than we knew. It means, says Brown, that “until recently, a relative shared the planet with us.”
Many scientists think a new species is unlikely. Some argue that the bones must have belonged to modern humans whose small size was the result of a genetic problem.
Daniel E. Lieberman, a scientist at Harvard University, thinks that the debate over the discovery is healthy. He believes that the questions and arguments raised by critics will help us learn more about these unusual skeletons. “Disagreement is an important part of the scientific process,” Lieberman said. “As far as I'm concerned, the story's only just begun.”

3．According to Daniel E. Lieberman ________.
A．Homo floresiensis doesn't exist
B．Disagreement leads to further research
C．The investigation hasn't begun yet
D．Our family tree is bigger than we knew
