American black bears appear in a variety of colors despite their name. In the eastern part of their range(地理分布区), most of these bears have shiny black fur, but in the west they grow brown, red or even yellow coats. To the north, the black bear is actually gray or white. Even in the same litter(窝), both brown and black furred bears may be born.

Black bears are the smallest of all American bears, ranging in length from 5 to 6 feet, weighing from 300 to 500 pounds. Their eyes and ears are small and their eyesight and hearing are not as good as their sense of smell. Like all bears, the black bear is shy, clumsy(笨拙的) and rarely dangerous. However, if cornered, me black bear can become a fearful enemy.

Black bears feed on leaves, roots, fruit, insects, fish and even larger animals. One of the most interesting characteristics of bears, including the black bear, is their winter sleep. Unlike many other animals, bears do not actually hibernate(冬眠). Although the bear does not eat during the winter months, its temperature remains almost normal, and it breathes regularly four or five times per minute.

Most black bears live alone, except during the mating season (交配李节). A litter of one to four cubs is born in January or February and they remain with their mother until they are fully grown or about one and a half years old. Black bears can live as long as thirty years in the wild, and even longer in game preserves set aside for them.

A British-designed electronic newspaper which is made of plastic and no larger than a table mat(垫子) is to enter the market next year. The new newspaper was conceived(想出) by Cambridge University scientists. They came up with the idea of replacing silicon chips (硅片) with plastic ones. it is being developed by Plastic Logic, a company based in Dresden, Germany.

"It looks just like a table mat, and is as light as a magazine. But you can download hundreds of newspapers at the touch of a button, and read them quite safely," the BBC reported on its website.

The plastic paper is produced in a safe "clean room" at the Plastic Logic factory, which opened last month as the world's first plastic-electronics factory. Every part of the product, from the screen to the electronics, is made of plastic. And it is described by engineer Dean Baker as "top quality". Baker says the plastic newspaper could help solve the problem of waste material associated with traditlional newspapers.

"There's a huge amount of waste . We have paper distributed(分发) all over the country each day and then thrown into the bin. This doesn't need to happen any more. All of the copies could be made electronically and stored on a single e-reader with the appearance of paper." he says.

I'm not so sure I like my friends any more. I used to like them-to be honest. We'd have lunch, talk on the phone or exchange e-mails, and they all seemed normal enough. But then came Facebook and I was introduced to a sad fact: many of my friends have dark sides that they had kept from me.

Today my friends show off the unpleasant aspects of their personalities via Facebook. No longer hidden, they're thrown in my face like TV commercials—unavoidable and endless advertisements for the worst of their personalities.

Take Fred. If you were to have lunch with him, you'd find him warm, and down-to-earth. Read his Facebook and you realize he's an unbearable, food-obsessed bore. He'd pause to have a cup of coffee on his way to save a drowning man—and then write about it.

Take Andy. You won't find a smarter CEO anywhere, but now he's a CEO without a company to run. So he plays “Mafia Wars” on Facebook. He's doing well-level 731.Thanks to Facebook, I know he's playing about 18 hours a day. Andy, you've run four companies—and this is how you spend your downtime? What happened to golf? What happened to getting another job?

Take Liz. She is positive that the H1N1 vaccine will kill us all and that we should avoid it. And then comes Chris who likes to post at least 20 times a day on every website he can find, so I get to read his thoughts twice, once on Facebook and once on Twitter.

In real life, I don't see these sides of people. Face to face, my friends show me their best. They're nice, smart people. But facing Facebook, my friends are like a blind date which goes horribly wrong.

I'm left with a dilemma. Who is my real friend? Is it the Liz I have lunch with or the anti-vaccine lunatic(狂人) on Facebook? Is it the Fred I can grab a sandwich with or the Fred who weeps if he's at a party and the wine isn't up to his standards?

1.Who is opposed to the H1N1 vaccine in the text?

A. Fred. B. Andy. C. Liz. D. Chris.

2.According to the text, Facebook tends to ________.

A. present another side of people

B. offer some food for free

C. show endless advertisements

D. get you to attend more parties

3.The text is developed mainly by ________.

A. giving examples B. following the time order

C. listing figures D. raising questions

4.The author focuses on the question of “________”.

A. what is Facebook? B. what happened to golf?

C. who is my real friend? D. who can help me?
