Facebook users may feel socially successful in the web world but they are more likely to perform poorly in exams. The majority of students who use Facebook every day are doing badly compared with those who don’t. About 83% of British 16 to 24-year-old people are using social networking site such as Facebook and MySpace, to keep in touch with friends and organize their social activities.

“Our study shows people who spend more time on Facebook spend less time studying,” said Aryn Karpinski, a researcher. “Every generation has its distractions(娱乐), but I think Facebook is a unique phenomenon.” Karpinski and a colleague questioned 219 US undergraduates and graduates about their study and general Internet use, as well as their specific use of Facebook. They found 65% of Facebook users accessed their account daily, checking it several times to see if they had received new messages. The amount of time spent on Facebook at each log-in(登录) varied from just a few minutes to more than an hour.

Some UK students have already realized the potential danger. Daisy Jones, 21, an undergraduate, realized the time she was spending on Facebook was threatening her grades, urging her to deactivate(使无效) her account, “I was in the library and tried to write a 2,000-word essay when I realized my Facebook habit had got out of hand,” she said. “I couldn’t resist going online, when thinking about it. Before you know it , a couple of minutes have turned into a couple of hours and you haven’t written a word.”

Jones is among the few to have realized the risks. 79% of the users, however, believed the time they spent on the site had no impact on their work. The CEO of Facebook said, “There is also academic research that shows the benefits of services like Facebook. It’s in the hands of students to decide how to spend their time.”

1.What can we know from Paragraph 1?

2.Facebook users check their account frequently to ____________.

3.Why did Daisy Jones deactivate her account?

4.What’s the best title of the passage ?

BUKHANNON, West Virginia—Two rescue teams slowly moved along a two-mile path on Monday night to the site of a coal mine explosion that trapped 13 miners, who had not been heard from since the early morning accident．
Meanwhile, at a nearby church, more than 250 family members and friends gathered, waiting for updates（最新报道）on the rescuers’ progress．
The miners were trapped at about 6:30 and many families weren’t informed of the accident until about 10 a．m-more than three hours after it happened．“It’s very upsetting, but you’ve got to be patient, I guess,” said John Helms, whose brother, Terry, was trapped in the mine．
The trapped miners were about 260 feet underground and about 10,000 feet from the Sago Mine’s entrance, said Roger Nicholson, general counsel from International Coal Group．
At a late night news conference, Nicholson said one team had advanced about 4, 800 feet in the four hours since entering the mine just before 6 p．m．Another team entered the mine about 30 minutes later．
He said the crew was very experienced, with some members having worked underground for 30 to 35 years．The miners were equipped with about one hour of breathable oxygen each．The company has not released the names of the miners．
The teams test the air about every 500 feet, and have to disconnect （remove） the power to the phones they use to communicate with the surface before doing that．“ We don’t want to be energizing anything if it’s in an atmosphere with burnable gases,” Kips said．
The cause of the explosion was not immediately known．High levels of carbon monoxide were discovered shortly after the explosion, which delayed rescue efforts, but those levels have since subsided（减退）, authorities said．
【小题1】According to the passage, we can infer that ________．

It’s only after three weeks into a new job that I made a serious mistake. My boss called it “extremely embarrassing” in a company-wide e-mail — which, __36__, he wrote because he felt he needed to explain that what I did was something __37__ in the company should ever do.
I wish I __38__ give a good excuse for what I did. At the very least, I wish I could explain it somehow — __39__ it on youth, inexperience or ignorance. Unfortunately, I’m __40__, experienced and I know better.
__41__ I work with some very kind and compassionate(富于同情心的) people. For the past couple of days many of them have taken time to __42__ by my desk and offer comfort, encouragement and support. Some have shared with me similar __43__ they have made. Evidently I’m not the only “ __44__ ” person here.
One of the exchanges I had this week was with Lois, the much-honored, much-respected professional who __45__ the desk right next to mine. Lois was completely __46__ about her work, and to be honest I was a little nervous about how she would __47__ to such an extremely embarrassing incident.
As I expected, Lois didn’t pass over the __48__ when she saw me the next day. She mentioned it directly, __49__ with empathetic(体恤别人感受的) consideration. She listened to my   __ 50__. Just as I was ready to express my regrets, she brought my self-pity partly to a(n)   __51__.
“It happened”, she said, “There’s nothing you can do to __52__ that. It happened. But it’s over now. It’s __53__. It’s in the past. You need to let it go, and move on.” And with that she returned her __54__ to her work, as if to say, “We’re done here.”
I beat myself up for weeks. At such times I need to remember those __55__ words: It’s over. It’s done. Let it go. And mostly, move on.

4.Which of the following shows the position where the miners were trapped?

Pushing children too hard is a really big social problem that seems to be getting worse．Now we have 6-month-olds in music classes and swimming classes．Parents fear that if other children are attending these classes，they will be holding their own children back if they do not enroll，too．

    The other extreme，simply taking a laissez-faire approach and letting children do—or refuse to do—whatever they want，is not the answer either，of course．

    Dr Taylor emphasizes that parents need to push their children based on what is best for the children，not what is best for themselves．If children understand that an activity is in their best interests，then they will accept it, he finds．

    Dr Taylor and other family experts remain pessimistic about the possibilities for widespread social change．“The force of our popular culture，driven by money and superficial（表面上的） values，cannot be resisted，” he says．But change can take place at a“micro-level,” in families and schools．

    When changes do occur，the rewards can benefit everyone in the family．One mother supporting this new approach toward parenting mentions the advantages her family experienced after her children cut back on activities．“The biggest thing is that since we have done this，we are rested,” she says．“Not only are our kids rested，because they're not in a ton of stuff, but my husband and I are rested，because we're not driving them everywhere．We weren’t living in the moment when we were always busy．We were living by the schedule．The return on our investment of spending time together has been enormous．”

One of the reasons why parents push children so hard is that they__________.

   A. believe in early development in children

   B. are too busy to take care of their children

   C. don't want their children to lag behindw(w w.ks&5 u.c*o m

The phrase“a laissez-faire approach”(in Line 1，Paragraph 2)most probably refers to      .

   A. denying them what they need

   B. controlling children in a flexible way

   C. developing a keen interest in children

   D. letting children do whatever they want

The best way to encourage children to work hard is           .

   A. to make them believe it’s in their best interests

   B. to consider the matter from parents' standpointw(w w.ks&5 u.c*o m

   C. to emphasize the importance of hard work from time to time

   D. to make it interesting and enjoyable to them

What the author doesn’t approve of in the essay is _______.

   A. achieving a balance between pushing the children too hard and leaving them alone

   B. going from one extreme of pushing children too hard to the other of leaving them alone

   C. involving children in activity that will probably contribute to their development

   D. enrolling them in music and swimming classes at the very early age

The new approach toward parenting mentioned in the passage most likely refers to _______.

   A. relieving children’s hard work and unnecessary activity

   B. resisting the superficial values of pop culture
