Each time I make a purchase on my credit card, the amount Ive spent and the name of the place Ive spent it automatically pop up on this weird new site.

2、Why would any sane person volunteer to publicize that information? Philip Kaplan, a technology entrepreneur and one of Blippys co-founders, hazards a guess: To tell peoplefriends acquaintances, maybe even strangersa little bit more about you. I had a different theory. If large numbers of people coul

3、d see and comment on what I was buying, maybe I would be shamed into spending less. Could there be a practical use for the exhibitionism and groupthink of social networking? Location-centric sites like Foursquare encourage people to blast where they are and what theyre buying. But Blippy takes thing

4、s to a new level, since information goes straight from point of purchase to website. You dont have to push a single button; just agree to let Blippy broadcast the details that end up on your credit-card statement. Marketers are constantly mining all sorts of consumer data, and Blippywhich has receiv

5、ed seed money from big-name investors like Sequoia Capital and Twitter CEO Evan Williamswants to help individuals start harnessing this kind of information too. Conversations on Blippy occasionally revolve around how people should spend less for things. If you pay more than $29.99 a month for a gym

6、membership, expect to hear about it. But more often the comments are pro-purchase. Thats especially true when people choose to specify what theyre buying on sites such as Amazon, iTunes and Netflix. During my first month on Blippy, which was in beta (测试) until Jan. 14, my inclination for eating at M

7、exican restaurants quickly became a topic of conversation among the strangers who started following me on the site. As I scrolled through other users purchases, I was reminded that most people sometimes go to grocery stores instead of eating out every night. I noticed another Blippy member joking ab

8、out how often charges showed up from a particular bar. He said that to avoid the appearance of a drinking problem, maybe he should switch to cash. I ran my cost-control theory by Kaplan, and he said it was interestingbut that he had witnessed his spending habits being swayed in the other direction.

9、On a recent trip to Bali, he battled with a friend over who would get to pay for dinner. He wasnt being gracious. He simply wanted the Blippy community to see that he was in a cool place. I, too, eventually found that sharing details about what I was buying only made me want to spend more. With frie

10、nds on New Years Eve, I asked to be the one to purchase a bottle of champagne. In an odd way, I felt I would be ringing in the New Year with my Blippy peers. And that made me realize Blippy isnt primarily about spending habits. Like any other social-networking site, its mostly about feeling as if yo

Im waiting for two girls I met on the Internet to show up and take me to their apartmen

16、t, so my friend Harry and I can stay there for free for a few nights. Having been on flights for the past 24 hours, I am worn out and nervous when they dont arrive on time. But my faith is restored when I hear a thick Chinese accent asking, Are you Cody? Even though Jess and Jin are as much stranger

17、s to me as anyone else in the bar, I trust them. It seems as natural as being set up by a mutual friend, and, in a sense, that is exactly what is happening. I first learned about CouchS last fall from my moms friend, who was planning on hosting travelers in her home to add a little excitement to lif

18、e after her oldest son went to college. She recommended I use it for an upcoming trip to Europe. Thats how I became one of the millions of surfers who search hosts profiles and send requeststypically as much as a week or as little as a day before arriving in the hosts cityto sleep on those peoples c

19、ouches or on their floor or in a spare bedroom. CouchSurfing requests are not always accepted, as my friend and I learned about seven hours before arriving at the bar in Hong Kong. During our stay in Tokyo, I found out via e-mail that the requests I had submitted that morning to two potential hosts

20、had both been politely declined. One host, had relatives visiting, and the other, was in Macau for the weekend. So, I quickly joined the forum Last Minute Couch Requests: Hong Kong and posted a message, which Jess saw. She got in touch with her friend Jin, who had room in her apartment to accommodat

21、e two guests. Jess sent us an e-mail, which we received after landing in Hong Kong, offering directions to a meeting place and a phone number. Harry and I could have dug through Jesss list of friends to read up on Jin, but instead we trusted that Jess would not lead us astray (走上邪路). After the girls

22、 get to the bar, the four of us go to a rooftop bar, then a club, and finally head back to Jins apartment. Over the next three days, the girls teach us how to use the public-transportation system and give us directions to popular tourist destinations. To outsiders like, say, my parents, it may be ha

23、rd to understand why Jin would agree to have two strangers stay at her place, or why we are even trying to couch-surf when hostels are cheap and plentiful in this part of the world. It is because couch surfing isnt just a means of accommodation; it is an entirely new way to travel. You get to see th

24、e world through local residents, not hotel gatekeepers or guidebooks. You get to step outside your comfort zones. But what is most profound about the whole experience is the trust that naturally exists. Jin, for instance, gives us a key to her place upon arrival, a common CouchSurfing custom that he

25、lps explain why sociologists at Stanford University are now studying the site and its ability to efficiently create trust. While cultural enrichment and adventure are almost a CouchSurfing guarantee, comfort is not. Jins guest mattress is not quite a quarter of an inch thick, the shower is too compl

26、icated for Harry or me to figure out, and the apartment is an eighth-floor walk-up. But its a tradeoff surfers like me are happy to make.（分数：12.50）(1).Which of the following is true about the friend of the authors mother?（分数：2.50）A.She got much help from CouchS for her last trip.B.She needed company

31、ss eight countries. The trend for late nights and early mornings was described as a ticking time bomb by the researchers at the University of Warwick who linked a lack of sleep to a range of disorders which often result in early death. Chronic short sleep produce hormones and chemicals in the body,

32、which increases the risk of developing heart disease, strokes and other conditions, according to Dr Michelle Miller of the University of Warwick. She and Professor Francesco Cappuccio, who co-authored a report published in the European Heart Journal , followed up evidence spanning seven to 25 years

33、from more than 470,000 participants across eight countries, including Japan, the US, Sweden and the UK. Professor Francesco Cappuccio said: If you sleep less than six hours per night and have disturbed sleep you stand a 48% greater chance of developing or dying from heart disease and a 15% greater c

34、hance of developing or dying from a stroke. The trend for late nights and early mornings is actually a ticking time bomb for our health so you need to act now to reduce your risk of developing these life-threatening conditions. Professor Cappuccio added: There is an expectation in todays society to

35、fit more into our lives. The whole work/life balance struggle is causing too many of us to trade in precious sleeping time to ensure we complete all the jobs we believe are expected of us. But in doing so, we are significantly increasing the risk of suffering a stroke or developing cardiovascular (心

36、血管的) disease resulting in, for example, heart attacks. He also warned of the implications of sleeping too much, more than nine hours at a stretch, which may be an indicator of illness, such as cardiovascular disease. He said: By ensuring you have about seven hours sleep a night, you are protecting y

37、our future health, and reducing the risk of developing chronic illnesses. The link is clear from our research: get the sleep you need to stay healthy and live longer. Ellen Mason, senior cardiac nurse at the British Heart Foundation, said: We know sleep is essential for staying healthy and this rese

38、arch adds further evidence about the possible consequences for our health if we dont get enough. Although there appears to be an association between heart and circulatory disease and lack of sleep, it is not yet fully understood. There seem to be some hormonal and chemical changes in the body when l

39、ack of sleep occurs, so over a period of time these may have some impact on the heart and circulatory system. There are plenty of reasons why sleep deprivation is a problem. Easy Internet access, a growing number of TV channels, financial worries and longer working hours all distract us from going t

40、o bed. But its important more of us make sleep a priority and get our restorative six to eight hours a night.（分数：12.50）(1).The phrase a ticking time bomb in the second paragraph is used to stress _.（分数：2.50）A.the risk of sleep deprivationB.our concern about good healthC.one possible cause of early d

44、between sleep and heart diseasesC.the hormones and chemicals changes in the bodyD.the importance of sleep for good healthDavid Fajgenbaum remembers the exact date: July 17, 2003. It was a warm evening in Washington, D.C., and the 18-year-old freshman had just finished his first football practice at

45、Georgetown University. It was awesome, the former quarter back recalls. He called his parents to let them know how well things were going. Davids dad, an orthopedic (整形手术的) surgeon, was oddly subdued. Finally, in a soft voice, he said, Son, your mom has brain cancer. I went from being happier than I

46、d ever been to total shock, says David. Rushing home, he announced he was dropping out of college to support his mother through her illness. But Anna Marie Fajgenbaum, just 52 years old and diagnosed with stage 4 brain cancer, was insistent that her son return to Georgetown. David threw himself into

47、 his studies and grew increasingly isolated. I felt I was the only person on campus with a sick parent. When everyones sitting around laughing and talking, you dont bring up your mothers latest MRI (磁共振) or say youve been crying. One October evening when David was home visiting, Anna Marie woke up w

48、eeping. She was worried about David and his two sisters. Mom, Im going to be okay, David assured her. Then, out of the blue, he said, And Im going to help other kids cope with loss. A smile spread across his mothers face. He decided on a support group called Ailing Mothers and Fathersbased on his moms initials, AMF. When Anna Marie died later that month, David started hearing from friends whod never even known his morn
