Everywhere you look, large quantities of information in the world are pouring. This data flood is already starting to transform business, government, science and everyday life. It has great potential for good — as long as consumers, companies and governments make the right choices about when to restrict the flow of data, and when to encourage it.
A few industries have led the way in their ability to gather and take advantage of the data. Credit-card companies monitor every purchase and can identify cheats with a high degree of accuracy. Stolen credit cards are more likely to be used to buy hard liquor than wine, for example, because it is easier to overlook. Insurance firms are also good at combining clues to spot doubtful claims: dishonest claims are more likely to be made on a Monday than a Tuesday, since policyholders (保险客户) who stage accidents tend to assemble friends as false witnesses over the weekend. By combining many such rules, it is possible to work out which cards are likeliest to have been stolen, and which claims are untrue. By analyzing “basket data”, supermarkets can make promotions to appeal to particular customers’ preferences. The oil industry uses supercomputers to help them before drilling wells.
But the data flood also poses risks. There are many examples of databases being stolen: disks full of social-security data go missing, laptops loaded with tax records are left in taxis, credit-card numbers are stolen by online purchase. The result can be privacy made public, identity stolen and cheats permitted large space. Rather than owning and controlling their own personal data, they very often find that they have lost control of it.
The best way to deal with the data flood is to make more data available in the right way, by requiring greater transparency in several areas. First, users should be given greater access to and control over the information held about them, including whom it is shared with. Google allows users to see what information it holds about them, and lets them delete their search histories or modify the targeting of advertising, for example. Second, organizations should be required to disclose details of security breaches (安全漏洞), as is already the case in some parts of the world, to encourage bosses to take information security more seriously. Third, organizations should be subject to an annual security check, with the resulting grade made public (though details of any problems exposed would not be). This would encourage companies to keep their security measures up to date.

We were on tour a few summers ago, driving through Chicago, when right outside of the city, we got pulled over. A middle-aged policeman came up to the car and was really being troublesome at first. Lecturing us, he said, “You were speeding. Where are you going in such a hurry?” Our guitarist, Tim, told him that we were on our way to Wisconsin to play a show. His way towards us totally changed. He asked, “Oh, so you boys are in a band(乐队)?” We told him that we were. He then asked all the usual band questions about the type of music we played, and how long we had been at it. Suddenly, he stopped and said, “Tim, you want to get out of this ticket, don’t you?” Tim said, “Yes.” So the officer asked him to step out of the car. The rest of us, inside the car, didn’t know what to think as we watched the policeman talk to Tim. Next thing we knew, the policeman was putting Tim in the back of the police car he had parked in front of us. With that, he threw the car into reverse(倒车),stopping a few feet in back of our car. Now we suddenly felt frightened. We didn’t know if we were all going to prison, or if the policeman was going to sell Tim on the black market or something. All of a sudden, the policeman’s voice came over his loudspeaker. He said, “Ladies and gentlemen, for the first time ever, we have Tim here singing on Route 90.” Turns out, the policeman had told Tim that the only way he was getting out of the ticket was if he sang part of one of our songs over the loudspeaker in the police car. Seconds later, Tim started screaming into the receiver. The policeman enjoyed the performance, and sent us on our way without a ticket. The policeman stopped the boys to.

Some of the planet’s most precious animals and plants are disappearing, according to the World Conservation Union (IUCN). The group, based in Switzerland, works with governments and experts to protect threatened species. On September 12, the IUCN released its Red List, a list of species at greatest risk of extinction.
The list includes 41,415 animals and plants. The IUCN says that habitat destruction, hunting and other causes threaten one in four mammals, one in eight birds and one in three amphibians(两栖动物).
Who is to blame?
Scientists believe that 99 percent of threatened species are at risk because of human activity. “We are losing animals and plants at a high rate,” says Julia Marton-LefEevre, director general of the IUCN. “We need to change our behavior.” Warmer oceans and over-fishing are changing sea life. This year for the first time corals(珊瑚) made their appearance on the list. The gharial, a crocodile living in India and Nepal, has lost almost 60 percent of its population in the last 10 years. It is a victim(受害者)of habitat destruction.
Still, the news is not all bad. Thanks to efforts made to protect it, the Mauritius echo parakeet, a bird once endangered, has seen an increase in its population. “This shows that protection methods can work,” says Marton-LefEevre. “That’s the message we want to send to young people.”
In China the new reserve(保护区)itself is part of green efforts that have seen more than 2,400 nature reserves of various kinds being set up, covering more than 15 percent of the nation's land area, official figures showed.
"The country's natural resources(资源) have benefited from conservation," said Lei Guangchun, director of the nature reserve department of Beijing Forestry University. "It is a big increase nowadays compared with other countries." Lei said.
The total areas of China’s natural reserves have covered 1.38 million km2, which accounts for 15.4% of China’s area, higher than both the world average(平均水平) of 11% and the rate in most developed countries.
Li Zhong, an official in charge of the nature reserves office with the State Forestry Administration, thought it was important to increase investment(投资) in such reserves at all levels. What do we know about the IUCN?
A.A union for listing animals and plants on the earth |
B.A group of volunteers who are interested in wildlife |
C.An organization concerning the protection of rare species' survival |
D.A government made up officials, scientists and experts |
What can be concluded from the passage?
A.All the protection methods can’t work. |
B.The IUCN does most of the protection. |
C.The efforts China makes has paid off. |
D.Enough is done in wildlife protection. |
Which of the following is not the cause of the disappearance of the animals?
A.Bad weather | B.Over-hunting | C.Warmer oceans | D.Habitat destruction |
Which of the sentence is NOT true?
A.China has been paying great attention to protecting the natural resources. |
B.China has set up a lot of natural reserves. |
C.The natural reserves in China cover more than 15 percent of the nation's land area. |
D.The rate of China's natural reserves is lower than the average of the world. |
Try and see inside your mind a wide open blue sky and a wide green sea far away. Breathe in as you circle your hands high above your head, then bend back a little. Breathe out as you circle your arms back down to your sides..."
Following the yoga teacher's gentle instructions, Bai Yunuo,15, from the High School attached to Beijing Normal University tried to get each of her poses correct.
Bai's school offered 24 elective courses (选修课) for Senor 1 students this term and she chose two. It was her first yoga class.
"I'm happy that I can learn yoga at school. I love dancing but I had some injuries on my knees when I was a kid. So I decide to try something soft. Simply stretching into different poses makes me feel free and quiet. And the music is quite comforting. The class is relaxing after a whole day's work," Bai said.
Liu Zehao,15, found his interest was Junior Achievement (企业经营模拟). The course brought students into the real world of business. In their first class, Liu and his group members named their company "Vision". Liu was elected as CEO of the company.
"Here we learn to think like an adult. We have to make our company get more money. It's new and different from other courses," he said.
Liu and Bai take their elective courses twice a week with students from other classes who share the same interest. The students will get two credits (学分) from each course at the end of this term. They have to achieve eight credit points from electives to graduate from high school.
