The practical conclusion is that if global warming is a potential disaster, the only solution is new technology.

Passage Two Someday a stranger will read your without your permission or scan the websites you39。 ve visited. Or perhaps someone will casually glance through your credit card purchases or cell phone bills to find out your shopping preferences or calling habits. In fact, it39。 s likely some of these things have already happened to you. Who would watch you without your permission? It might be a spouse, a girlfriend, a marketing pany, a boss, a cop or a criminal. Whoever it is, they will 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 it39。 s important to reveal yourself to friends, family and lovers in 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 some cases, a simple Google search can reveal what you think. Like it or not, increasingly we live in a world where you simply 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 found an 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 effort to preserve their privacy. Few people turn down a discount at tollbooths(收费站 ) to avoid using the EZPass system that can track automobile movements. And few turn down supermarket loyalty cards. Privacy economist Alessandro Acquisti has run a series of tests that reveal people will surrender personal information like Social Security numbers just to get their hands on a pitiful 50centsoff coupon(优惠券 ) • But privacy does matter — at least sometimes. It39。 s like health； when you have it, you don39。 t notice it. Only when it39。 s gone do you wish you39。 d done more to protect it. 62. What does the author mean by saying “ the 21st century equivalent of being caught naked(Lines 34, Para. 2)。 A) People39。 s personal information is easily accessed without their knowledge. B) In the 21st century people try every means to look into others39。 secrets. C) People tend to be more, frank with each other in the information age. D) Criminals are easily caught on the spot with advanced technology. 63. What would psychologists advise on the relationships between friends。 A) Friends should open their hearts to each other. B) Friends should always be faithful to each other. C) There should be a distance even between friends. D) There should be fewer disputes between friends. 64. Why does the author say “ we live in a world where you simply cannot keep a secret” (Line 5, Para. 3)。 A) Modern society has finally evolved into an open society. B) People leave traces around when using modern technology. C) There are always people who are curious about others39。 affairs. D) Many search engines profit by revealing people39。 s identities. 65.
