PRE-READING TASK

Exercise 1
Before reading the passage, try to answer the questions.

1. How much do you know about the Internet?
2. What do people usually do on the Internet?
3. What has made the Internet possible?

Modern Communication:
The Laser and Fiber1-Optic Revolution

1. In April 1995, a young Chinese chemistry student at Beijing University lay dying in a Beijing hospital. She was in a coma2, and although her doctors had performed numerous tests, they could not discover what was killing3 her. In desperation, a student friend posted an SOS describing her symptoms to several medical bulletin boards and mailing lists on the Internet. Around the world, doctors who regularly checked these electronic bulletin boards and lists responded immediately.
2. In Washington, D.C., Dr. John Aldis, a physician with the U.S. Department of State, saw the message from China. Using the Internet, he forwarded the message to colleagues in America. Soon an international group of doctors joined the e-mail discussion. A diagnosis4 emerged -- the woman might have been poisoned with thallium, a metal resembling lead. A Beijing laboratory confirmed this diagnosis -- the thallium concentration in her body was as much as 1000 times normal. More e-mail communication followed, as treatment was suggested and then adjusted. The woman slowly began to recover. Well over a year later, the international medical community was still keeping tabs on her condition through the electronic medium that saved her life.
3. It's 11:30 p.m., you're in San Francisco on business, and you want to check for messages at your office in Virginia. First you dial in and get your voice mail. Next you plug your portable computer into the hotel-room telephone jack6, hit a few keys, and pick up e-mail from a potential client in South Africa, your sister in London, and a business associate in Detroit. Before writing your responses, you do a quick bit of search on the Internet, tracking down the name of the online news group you had mentioned to the man in Detroit and the title of a book you wanted to recommend to your sister. A few more keystrokes and in moments your electronic letters have reached London and Detroit. Then, knowing that the time difference means the next workday has begun in South Africa, you call there without a second thought.
4. These stories reflect society's increasing reliance on a system of global communication that can link you equally easily with someone in the next town or halfway7 around the world. The expanded telephone-line capacity that has allowed the growth of these forms of communication is a recent phenomenon. The United States has enjoyed domestic telephone service for more than a century, but overseas telephone calls were difficult until relatively8 recently. For a number of years after World War II, calls to Europe or Asia relied on short-wave radio signals. It sometimes took an operator hours to set up a 3-minute call, and if you got through, the connection was often noisy.
5. In 1956, the first transatlantic copper9 wire cable allowed simultaneous transmission of 36 telephone conversations -- a cause for celebration then, a small number today. Other cables followed; by the early 1960s, overseas telephone calls had reached 5 million per year. Then came satellite communication in the middle 1960s, and by 1980, the telephone system carried some 200 million overseas calls per year. But as demands on the telecommunication10 system continued to increase, the limitations of current technology became apparent. Then, in 1988, the first transatlantic fiber-optic cable was laid, and the "information superhighway" was on its way to becoming reality.
6. Optical fibers11 form the backbone12 of the global telecommunication system today. These remarkable13 strands15 of glass -- each thinner than a human hair, yet stronger, length for length, than steel -- were designed to carry the vast amounts of data that can be transmitted via a relatively new form of light -- tightly focused laser beams. Together, lasers and optical fibers have dramatically increased the capacity of the international telephone system. A typical fiber-optic cable made up of 100 or more such fibers can carry more than 40000 voice channels. With equally striking improvements in computing16, the new communication technology has fueled the exponential growth of the phenomenon known as the Internet.
