For computer users, there is no bigger excitement than tossing out your old PC and upgrading to a newer, faster and cleaner machine. With hardware designers like Intel, pushing newer, faster products every year, and new software requiring even more powerful machines, companies and consumers have little choice but to go along.
But this rapid turnover is having a serious effect on the planet. Producing a personal computer consumes large quantities of natural resources. A recent study by the United Nations estimates the energy required to produce a single new computer is equivalent to nearly two barrels of oil. And that doesn't include the 22 kg of chemicals or the 1,500 kg of water used in the manufacturing process.
In fact, pound for pound(均等地), the process for making a car is about 500% more efficient than that for making a computer. That doesn't matter so much 20 years ago when personal computers were few and far between, but times have changed. These days, computers are found nearly everywhere and sales continue to grow. The number of PCs in use topped one billion in 2002.
Waste in production is only half the problem. Old computers, especially the monitors, are full of dangerous substances, which need to be carefully recycled. The problem is sure to expand over the coming years as users replace their boxy CRT monitors with LCD flat displays.
Europe now requires that 70% of parts from old computers be recycled, but the study’s authors say that’s also part of the problem. The solution, they insist, is for governments and companies to encourage people to use their computers longer, and upgrade rather than replace. But considering that much of the world’s recent economic growth has come from spending on computers and information technology, that advice may sound like wishful thinking.

How would you like an easy way to earn $2,500? All you have to do is to sit around and wait for your meals. There's a catch however. You have to stay in a chicken cage with a stranger for a whole week. There are no books or television or radio for amusement. You can't leave until the week is up. And a camera will be recording your every move.
Two people actually took the job. The idea came from Rob Thompson, a video artist. He wanted to make a film about the way animals are treated. His goal was to raise people's awareness of the living conditions of animals that are raised for food.
He decided to pay $5,000 out of his own savings to two people who were willing to live like chickens for a week.
To Rob’s surprise, quite a few people answered his advertisement. He had interviewed and selected Eric, a 24-year-old restaurant worker, and Para, a 24-year-old chemist. The plan was for them to spend seven days together in a chicken cage that was six feet long and three feet wide. A camera would record their experiences, which would take place in an art museum.
The week was long and difficult. They slept on a hard wooden floor. They couldn't stand up without hanging their heads. They ate vegetables and drank water from a garden hosepipe. Their only privacy was a toilet surrounded by a curtain. There were no sinks, mirrors, or toothbrushes in the cage. Their only inspiration was the two framed checks that hung on the wall outside the cage. Visitors who came here were warned, “Do not feed the humans.”
Finally it was over, and Para and Eric appeared from their cage. They had survived the week, and they each had a $2,500 check in their hands. When Rob Thompson opened the cage, Eric came out, changed into clean clothes, and ate a chocolate bar right away. “It's great to be able to stand up,” he said. Para just changed her clothes and left. After a week of visitors and reporters watching her, she
didn't want to talk to anyone.
1.What kind of person is Rob Thompson?
A. He is curious about people's personal life.
B. He is kind-hearted to animals.
C. He hates people around.
D. He likes to help poor people.
2.The underlined word “catch” probably means _____.
A. unsolved problem B. surprising wonder
C. unbelievable fact D. hidden difficulty
3.Rob offered the money because he wanted _____ .
A. to see if there were any people who would like to live in a cage
B. to show the public how terrible animals' life could be
C. to make more money by publishing the recorded videotapes
D. to improve housing conditions of working people like Eric
