When Gretchen Baxter gets home from work as a New York City book editor, she checks her Blackberry (黑莓手机) at the door. ‘I think we are attached to these devices in a way that is not always positive,’ says Baxter，who’d rather focus at home on her husband and 12-year-old daughter. ‘It’s there and it beckons (召唤). That’s human nature (but)…we kind of get crazy sometimes and we don’t know where it should stop.’
Americans are connected at unprecedented (前所未有的) levels一93% now use cell phones or wireless devices；one third of those are ‘smart phones’ that allow users to browse the Web and check e-mail，among other things. The benefits are obvious: checking messages on the road，staying in touch with friends and family，efficiently using time once spent waiting around. The downside：often，we’re effectively disconnecting from those in the same room.
That's why，despite all the technology that makes communicating easier than ever，2010 was the Year We Stopped Talking to One Another. From texting at dinner to posting on Facebook from work or checking e-mail while on a date，the connectivity revolution is creating a lot of divided attention，not to mention social anxiety. Many analysts say it's time to step back and reassess.
‘What we’re going to see in the future is new opportunities for people to be plugged in and connected like never before,’ says Scott Campbell. ‘It can be a good thing，but I also see new ways the traditional social fabric (社会结构) is getting somewhat torn apart.’
Our days are filled with beeps and pings·----many of which pull us away from tasks at hand or face-to-face conversations. We may feel that the distractions are too much，but we can’t seem to stop posting，texting or surfing.
‘We're going through a period of adjustment and rebalancing,’ says Sherry Turkle and she wants to remind people that technology can be turned off.
‘Our human purposes are to really have connections with people,’ she says. ‘We have to reclaim it. It’s not going to take place by itself.’
【小题1】What can be the best title for the passage?

Generations of Americans have been brought up to believe that a good breakfast is essential to one's life. Eating breakfast at the start of the day, we have been told, and told again, is as necessary as putting gasoline in the family car before starting a trip.
But for many people, the thought of food as the first thing in the morning is never a pleasure. So in spite of all the efforts, they still take no breakfast. Between 1977 and 1983, the latest year for which figures could be obtained, the number of people who didn’t have breakfast increased by 33%—from 8.8 million to 11.7 million—according to the Chicago-based Market Research Corporation of America.
For those who dislike eating breakfast, however, there is some good news. Several studies in the last few years have shown that, for grown-ups especially, there may be nothing wrong with omitting breakfast. “Going without breakfast does not affect work,” said Arnold E. Bender, former professor of nutrition at Queen Elizabeth College in London, “nor does giving people breakfast improve work.”
Scientific evidence linking breakfast to better health or better work is surprisingly inadequate, and most of the recent work involves children, not grown-ups. “The literature,” says one researcher,  Dr Earnest Polite at the University of Texas, “is poor.”

Dear all,
Please read Professor Hume’s email about his next lecture on Rosa I’arks.
Susan Miller
Secretary
Dear Susan,
Please forward this message to students of my history class.
Besides the life story of Bosa Parks in the textbook,the students are also required to read the passage below and some related stories that can be borrowed from the school library.
Ted Hume
The early experiences of Rosa Parks (1913-2005),long known as the “mother of the civil rights movement,”were not different from those of many African-Americans at that time.The black woman,however,turned the course of American history in December 1955 when she refused to give up her seat on a bus to a white man.“By sitting down,”remarked John Lewis,“she was standing up for all Americans.”
Among the numerous awards Parks received in her life were the Presidential Medal of Freedom (1996) and the Congressional Gold Medal(1999).
Parks died on Oct. 24,2005,At St. Paul A.M.E. Church in Montgomery,a large crowd including Secretary of State Condoleezza Rice celebrated her life.Rice said she and others,who grew up when the political activities of Parks held public attention,might not have realized her impact(影响) on their lives,“but I can honestly say that without Mrs. Parks,I probably would not be standing here as Secretary of State.”
After her casket(灵柩) was placed at the Capitol,U.S. President Bush,members of Congress and ordinary Americans paid their respects.In American history Parks is the first woman to lie in state at the Capitol,a very high regard usually reserved for Presidents of the United States.
【小题1】What is the main purpose of Susan’s email?

Online shoppers would rather receive an offer for a product or service than make their own offer ₃ according to a study led by a Michigan State University scholar that has implications for the fast-growing e-commerce industry. The findings may come as a surprise given that shopping online is an anonymous(匿名的）process that seemingly can give consumers more confidence to drive a hard bargain_,said Don Conlon ，Professor of Management in MSU’s Broad College of Business.
But the study found that participants who made their own offers were less successful in sealing the deal and ，when they were successful_? worried they overpaid Many shoppers found the process of researching an offer to be a hassle. “ Americans are very busy，and it’s less time-consuming to be the one receiving the offer rather than the one proposing the offer  ” Conlon said. ^u People tend to be happier when they’re in the receiver role. ”
Online spending in the United States is expected to jump 45 percent in the next four years， from $ 226 billion this year to $ 327 billion in 2017，according to Forrester Research Inc. Nevertheless, researches into this prosperous market remain largely focused on the strategies of companies, rather than those o£ shoppers. Conlon^’s study is ，obviously, a rare exception.
Conlon got the idea for the study after considering the difference between two popular sites for hotels and airline flights, priceline.com, which takes bids, and hotwire.com ，which provides offers. Using these two models ，Conlon and his fellow researchers conducted a series of experiments with more than 850 people who were charged with booking a fictional hotel room and acquiring a fictional antique car. Not only did participants prefer to receive bids, Conlon said ，but they also secured more deals in that receiver role. Further ，when they had to make the bids ，they were left more mentally taxed and regretful.
From an industry perspective，putting customers in the receiver role may help fill more hotel rooms and airplane seats. “If you’re a business with a lot of products₃ ” Conlon said，“you may want to be the one making the offers. ” However, when selling single items, such as an antique car， accepting bids may be a better option since that typically drives up the price, he said.

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

For several years, Americans have enjoyed teleshopping-watching TV and buying things by phone.        In a number of European countries, people can turn on their TVs and shop for clothes, jewelry, food, toys, and many other things.

     For example, the biggest Swedish company sells different kinds of things on TV in 15 European countries, and in one year it made $ 100 million. In France there are two teleshopping channels, and the French spend about $20 million a year to buy things through those channels.

In Germany, until last year teleshopping was only possible on one channel for 1 hour every day. Then the government allowed more teleshopping. Other channels can open for telebusiness, including the largest American teleshopping company and a 24-hour teleshopping company.  .

Some people like teleshopping because it allows them to do their shopping without leaving their homes. With all the problems of traffic in the cities, this is an important reason, but at the same time, other Europeans do not like this new way of shopping.   Many Europeans usually worry about the quality of the things for sale on TV. Good quality is important to them, and they believe they cannot be sure about the quality of the things on TV.

   They will have to be more careful about the quality of the things they sell. They will also have to work harder to sell things that the buyers cannot touch or see in person.

       A. Now teleshopping is starting in European

       B. They call teleshopping “Junk on the air”
