l without your permission or scan the Websites youve visited. Orperhaps someone will casually glance through your credit card purchases or cell phone bills to find out yourshopping preferences or calling habits. In fact, its likely some of these things have already happened to you. Who would watch you without yourpermission？ It might be a spouse, a girlfriend, a marketing company, a boss, a cop or a criminal. Whoever it is, theywill see you in a way you never intended to be seen--the 21st century equivalent of being caught naked. Psychologists tell us boundaries are healthy, that its important to reveal yourself to friends, family and loversin stages, at appropriate times. But few boundaries remain. The digital bread crumbs (碎屑) you leave everywhere make it easy for strangers to reconstruct who you are, where you are and what you like. In somecases, a simple Google search can reveal what you think. Like it or not, increasingly we live in a world where yousimply cannot keep a secret. The key question is: Does that matter？ For many Americans, the answer apparently is "no." When opinion polls ask Americans about privacy, most say they are concerned about losing it. A survey foundan overwhelming pessimism about privacy, with 60 percent of respondents saying they feel their privacy is"slipping away, and that bothers me." But people say one thing and do another. Only a tiny fraction of Americans change any behaviors in an effortto preserve their privacy. Few people turn down a discount at tollbooths (收费站) to avoid using the EZ-Pass system that can track automobile movements. And few turn down supermarket loyalty cards. Privacyeconomist Alessandro Acquisti has run a series of tests that reveal people will surrender personal information likeSocial Security numbers just to get their hands on a pitiful 50-cents-offcoupon(优惠劵). But privacy does matter--at least sometimes. Its like health: When you have it, you dont notice it. Only when its gone do you wish youd done more to protect it.

been halved. No, youre not an investor in one of those hedge funds that failed completely. With the dollar slumping to a 26-year low against the pound, already- expensive London has become quite unaffordable. A coffee at Starbucks, just as unavoidable in England as it is in the United States, runs about $8. The once all-powerful dollar isnt doing a Titanic against just the pound. It is sitting at a record low against the euro and at a 30-year low against the Canadian dollar. Even the Argentine peso and Brazilian real are thriving against the dollar. The weak dollar is a source of humiliation (屈辱), for a nations self-esteem rests in part on the strength of its currency. Its also a potential economic problem, since a declining dollar makes imported food more expensive and exerts upward pressure on interest rates. And yet there are substantial sectors of the vast U.S. economy--from giant companies like Coca-Cola to morn-and-pop restaurant operators in Miami--for which the weak dollar is most excellent news. Many Europeans may view the U.S. as an arrogant superpower that has become hostile to foreigners. But nothing makes people think more warmly of the U.S. than a weak dollar. Through April, the total number of visitors from abroad was up 6.8 percent from last year. Should the trend continue, the number of tourists this year will finally top the 2000 peak. Many Europeans now apparently view the U.S. the way many Americans view Mexico--as a cheap place to vacation, shop and party, all while ignoring the fact that the poorer locals cant afford to join the merrymaking. The money tourists spend helps decrease our chronic trade deficit. So do exports, which, thanks in part to the weak dollar, soared 11 percent between May 2006 and May 2007. For the first five months of 2007, the trade deficit actually fell 7 percent from 2006. If you own shares in large American corporations, youre a winner in the weak-dollsr gamble. Last week Coca-Colas stock bubbled to a five-year high after it reported a fantastic quarter. Foreign sales accounted for 65 percent of Cokes beverage (饮料) business. Other American companies profiting from this trend include McDonalds and IBM. American tourists, however, shouldnt expect any relief soon. The dollar lost strength the way many marriages break up--slowly, and then all at once. And currencies dont turn on a dime. So if you want to avoid the pain inflicted by the increasingly pathetic dollar, cancel that summer vacation to England and look to New England. There, the dollar is still treated with a little respect. Why do Americans feel humiliated？

A.Their economy is plunging.

B.Their currency has slumped.

C.They cant afford trips to Europe.

D.They have lost half of their assets.
