题目内容
In the early days of the Internet, the idea that it represented an entirely new and separate field distinct from the real world was seized upon by both supporters and critics of the new technology.Supporters liked the idea that the virtual (虚拟的) world was a placeless datasphere, liberated from constraints and restrictions of the real world, and an opportunity for a fresh start.For instance, John Perry Barlow, an internet activist, issued the "Declaration of the Independence of Cyberspace" in February 1996.He thundered, "Governments of the industrial world, I come from cyberspace, the new home of mind.Cyberspace does not lie within your borders.We are creating a world that all may enter without privilege or prejudice accorded by race, economic power, military force, or station of birth.
Where Mr.Barlow found the separation between the real and virtual worlds exciting, however, critics regarded it as a cause for concern.They worried that people were spending too much time online, communicating with people they had never even met in person in chat rooms, virtual game worlds and, more recently, on social - networking sites such as MySpace and Facebook.A study carried out by the Stanford Institute for the Quantitative Study of Society in 2000, for example, found that heavy internet users spent less time talking to friends and family, and warned that the Internet could be "the ultimate isolating( 隔离) technology".
Both groups were wrong, of course.The Internet has not turned out to be a thing apart.Unpleasant aspects of the real world, such as taxes, crime and cheating are now characteristics of the virtual world, too.C'amers who make real money selling swords, gold and other things in virtual game worlds may now find that the tax man wants to know about it.Designers of virtual objects in Second Life, an online virtual world, are seeking to real -world lawsuits (诉讼) in order to protect their intellectual property.
At the same time, however, some of the most exciting uses of the Internet rely on combining it with the real world.Social networking allows people to stay in touch with their friends online, and plan social activities in the real world.The distinction between online and offline chatters does not matter any more.
All these approaches treat the Internet as an extension or an attachment to the physical world, not a separate space.Rather than seeing the real and virtual fields as distinct and conflicting, in short, it makes sense to see them as complementary and connected.

Parties, iPods, concerts, movies, TV shows, video games, traffic. All of these things of the modern world make life entertaining and enjoyable. But our 21st-century lifestyle is also loud and, if we don’t take notice, it can have an effect on our hearing.
Most teenagers don’t think about hearing loss. But if you experience any of the following symptoms(症状), you may already be hearing damaged: you make efforts to hear normal talk, you have to turn up the TV or radio so high that others complain, you watch other people’s expressions to understand what they are saying, you ask people to repeat themselves, you misunderstand what people are saying or you hear ringing in your ears.
iPods and other MP3 players are as common as the clothes you wear, and just as fashionable. But if you turn up an iPod to more than 60 percent of its maximum volume(最大音量), and listen to music for more than an hour, you are asking for trouble. And, it does not matter if the music you play is classical, rock or heavy metal.
Some researchers find that young people who break the so-called 60-percent/60-minute rule in listening to iPods are at the risk of suffering hearing loss.
Why is an iPod dangerous? With ear buds placed directly in the ear canal and high-volume music played over a long period of time, it’s like working in a loud factory all day, being a maintenance(修理)person under a jet airplane or using a jackhammer(手提钻)on a building site.
Similarly, iPod music can cause a short time or permanent(永久的)hearing damage. A loud iPod can cause a ruptured(破裂的)eardrum and, over time, may cause permanent damage to the tiny hairs in the inner ear. If these tiny hairs are damaged, they cannot effectively send sounds to the auditory nerves(听觉神经)that connect to the brain. If this happens, hearing loss becomes permanent.

| A.You are interested to listen to others’ talking. |
| B.You have to read others’ expressions to understand them. |
| C.You can only understand others over the phone. |

d. Ear buds are placed directly in the ear canal.

| A.d-a-c-b-e | B.e-c-a-b-d | C.b-c-a-d-e | D.d-e-a-c-b |
