Teens don’t understand the big fuss. As the first generation to grow up in a wired world, they hardly know a time when computers weren’t around, and they eagerly catch the chance to spend hours online, chatting with friends. So what?

But researchers nationwide are increasingly worried that teens are becoming isolated, less skillful at person-to-person relationships, and perhaps numb to the cheatings that are so much a part of the e-mail world. “and a teen’s sense of self and values may be changed in a world where personal connections can be limitless,” said Sherry Turkle.

Another researcher, Robert Kraut, said he’s worried about the “opportunity costs” of so much online time for youths. He found that teens who used computers, even just a few hours a week, showed increased signs of loneliness and social isolation. “Chatting onine may be better than watching television, but it’s worse than hanging out with real friends,” he said.

Today’s teens, however, don’t see anything strange in the fact that the computer takes up a central place in their social lives, “School is busy and full of pressure. There’s almost no time to just hang out.” said Parker Rice, 17. “Talking online is just catch up time.”

Teens say they feel good about what they say online or taking the time to think about a reply. Some teens admit that asking someone for a date, or breaking up, can be easier in message form, though they don’t want to do so. But they insist there’s no harm.

Watching bison up close is fascinating, like watching a grass fire about to leap out of control. With their huge, wedge-shaped heads and silver-dollar-size brown eyes, the 2,000-pound animals are symbols of another place and time. More than 100 bison now roam the 30,000-acre American Prairie Reserve in eastern Montana — the first time they’ve inhabited that region in a century. Direct descendants of the tens of millions of bison that once populated the Western plains, they represent an epic effort： to restore a piece of America’s prairie to the national grandeur that Lewis and Clark extolled two centuries ago. During that famous expedition across the Western states to the Pacific, the two explorers encountered so many bison that they had to wait hours for one herd to pass.

In order to protect what’s here and reintroduce long-gone wildlife (something the World Wildlife Fund is helping with), the American Prairie Foundation began purchasing land from local ranchers in 2004. It now owns 30,000 acres and has grazing privileges on another 57,000. Its goal over the next 25 years is to assemble three million acres, the largest area of land devoted to wildlife management in the continental United States.

Already, herds of elk, deer, and pronghorn antelope roam the grasslands, where visitors can camp, hike, and bike. Cottonwoods and willows are thriving along streams, creating habitats for bobcats, beavers, and other animals.

Not everyone shares APF’s vision. Some residents of Phillips County (pop. 3,904) worry that the area could become a prairie Disneyland, overcrowded with tourists. But the biggest obstacle is the ranchers themselves, whose cattle compete with prairie dogs and bison for grass and space.

“People like me have no intention of selling their ranches,”says Dale Veseth, who heads the Ranchers Stewardship Alliance of 35 families in Phillips County and whose family has been ranching here since 1886.“They’ve been a labor of love through the generations.”Instead, he wants APF to pay or subsidize ranchers to raise bison. This would be far less costly for the foundation, he argues, than buying the land directly.

63．If you go to the American Prairie Reserve in eastern Montana, you will see ________.

       A．the burning fire moving across the grassland

       B．hundreds of bison travelling through the prairie

       C．tens of millions of bison occupying the farmland

       D．groups of experts examining the dead bison

64．What measures have been taken to protect the wildlife by APF?

       A．They have borrowed much money and developed new habitat.

       B．They have hired many farmers to raise bison on their farms.

       C．They have turned grassland into Disneyland to attract tourists.

       D．They have bought large land from farmers for bison to live on.

65．The underlined word“subsidize”in this passage means ________.

C．provide land to     D．exchange land with

66．Which would be the best title for this passage?

Dangerous creatures

Some beach creatures are wonderful—like dolphins, but others are dangerous. Find out more about the dangerous ones –puffer fish, blue ringed octopus, and stingrays.

The blue ringed octopus

The blue ringed octopus is not a very big creature but it is very dangerous.

These octopuses are found all around the coast of Australia. They often lie in rock pools close to shore.

The blue ringed octopus is usually a dull colour but it shows its bright blue rings when it is in danger. If it is taken out of the water by someone, it is able to bite him and poison him.

If this creature bites someone, he will feel numbness (麻木) around the mouth, face and neck, Puffer Fish

Puffer Fish are found in all Australian seas. They are very easy to catch but must not be eaten because their flesh contains a poison.

Anyone who does eat the flesh can become sick very quickly. They may even stop breathing.

The Blue Bottle

The Blue Bottle is found in most Australian waters. Blue Bottles float lightly on the surface of the water but their tentacles(觸角)can be as long as 10 meters.

Blue Bottles are much less dangerous than some other jellyfish, but they can give a swimmer a bad sting(刺) if the swimmer accidentally touches them.

Stingrays

There are many different kinds of stingrays in Australian waters. They usually swim and feed on the bottom of the sea. Accidents can happen if people stand on them or try to pick them up.

Stingrays have a sting on their tail. These stings have poison on them. If someone is stung, the wound can easily become infected.

If you swim in Australian waters, you will probably             .

       A．be bitten by the blue ringed octopus

       B．stop breathing because of Puffer Fish

       C．get a bad sting by the Blue Bottle

       D．become infected by stingrays

       A．a(chǎn)ll creatures along the coast of Australia are dangerous

       B．poisonous creatures change the body color when in danger

       C．no accident will happen unless people touch these creatures

       D．if people stand on the beach, accidents can happen because of creatures

       C．wild creatures in Australia seas       D．different creatures in Australian waters

In a few years, you might be able to speak Chinese, Korean, Japanese, French, and English -- and all at the same time. This sounds incredible, but Alex Waibel, a computer science professor at US' s Carnegie Mellon University (CMU) and Germany' s University of Karlsruhe, announced last week that it may soon be reality. He and his team have invented software and hardware that could make it far easier for people who speak different languages to understand each other.

One application, called Lecture Translation, can easily translate a speech from one language into another. Current translation technologies typically limit speakers to certain topics or a limited vocabulary. Users also have to be trained how to use the programme.

Another prototype (雛形機(jī)) can send translations of a speech to different listeners depending on what language they speak. "It is like having a simultaneous translator right next to you but without disturbing the person next to you," Waibel said.

Prefer to read? So-called Translation Glasses transcribe (轉(zhuǎn)錄) the translations on a tiny liquid-crystal(液晶) display (LCD) screen.

Then there' s the Muscle Translator. Electrodes (電極) capture the electrical signals from facial muscle movements made naturally when a person is mouthing words. The signals are then translated into speech. The electrodes could be replaced with wireless chips implanted (植入) in a person' s face, according to researchers.

During a demonstration (演示) held last Thursday in CMU' s Pittsburgh campus, a Chinese student named Stan Jou had 11 tiny electrodes attached to the muscles of his cheeks, neck and throat. Then he mouthed -- without speaking aloud -- a few words in Mandarin(普通話) to the audience. A few seconds later, the phrase was displayed on a computer screen and spoken out by the computer in English and Spanish: "Let me introduce our new prototype".

This particular gadget (器械), when fully developed, might allow anyone to speak in any number of languages or, as Waibel put it, "to switch your mouth to a foreign language". "The idea behind the university' s prototypes is to create 'good enough' bridges for cross-cultural exchanges that are becoming more common in the world," Waibel said.

With spontaneous (自發(fā)的) translators, foreign drivers in Germany could listen to traffic warnings on the radio, tourists in China could read all the signs and talk with local people, and leaders of different countries could have secret talks without any interpreters there.

What kind of prototype did the Chinese student named Stan Jou try?

A. Lecture Translation.            B. Translation Glasses.

C. Muscle Translator.             D. We don' t know.

What is the purpose of inventing the translators?

    A. To help students to learn English.

    B. To help people to watch foreign TV programs.

    C. To help people travel in foreign countries.

    D. To promote cultural exchanges between countries.

What is the best title of this text?

    A. Speak different languages at the same time?

    B. Flow to learn to speak foreign languages?

    C. New ways to learn foreign languages

D. You' re welcome to learn foreign languages
