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, its 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 company, 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 its important to reveal yourself to friends, family and lovers in stages, at appropriate times. But few boundaries remain. The digital bread crumbs ( ) 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 ( ) to avoid using the EZ-Pass 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 50-cents-off coupon ( ) . 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.1. What does the author mean by saying “ the 21st century equivalent of being caught naked” (Lines 4, Para. 2)?A. Peoples personal information is easily accessed without their knowledge.B.

Criminals are easily caught on the spot with advanced technology.2. 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.3. 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 others affairs.D. Many search engines profit by revealing peoples identities.4.

In 2040 it will not matter. They will turn themselves off- and on again when you return. You will choose the temperature for each room , the lighting and the humidity. A sensor will detect the presence of a human (and, with lich, ignore the dog!) and turn the systems on, and when the humans leave, it will turn them off again. The sensors will work through the central home computer, and they will do much more than just turn the fires and lights on and off for you. They will detect faulty electrical appliances, plugs or switches, isolate them so that they cannot harm anyone, and then warn you that they need repair. They will detect fire and if you are out of the house, the computer will call the faire brigade. It will also call the police should the sensors detect an intruder. This will not be very difficult because the locks on the outside doors will be electronic. Youll open them using your personal card- the one you use for shopping- maybe using a number known only to you. It will be impossible to lose the key, and a house breaker will have to tamper( ) with the lock or with a window. It is not very difficult to make such tampering send a signal to the computer. The computer will be more than a fireman-policeman-servant. It will be an entertainer, and most of your entertainment will come right into your home. It does now, of course, but by 2040 “entertainment” will mean much more. For on e thing, you will be able to take part actively, rather than just waiting.6.
