ЗАДАНИЯ ПО vocabulary science and technology words. Lesson 7 Science in the News: Avoiding Potholes on the Information Highway
Jean Armour Polly, a former librarian, has been working with computers and modems for 20 years. In a 1992 magazine article, she coined the term “surfing the Internet.” Today, she is a best-selling author. Her book, The Internet Kids and Family Yellow Pages, has helped hundreds of thousands of young people learn to navigate the Net safely, comfortably, and productively. The book has recently come out in its fifth edition. Mrs. Polly says that the best Web sites for young people should meet certain criteria: They should have authority, currency, and an acceptable “signal-to-noise ratio.” No less importantly, the sites should be age-appropriate. Specifically, the author gives this advice: •Authority Ask yourself who is behind the site. Is it a reputable source such as National Geographic or someone you never heard of? Make sure the information comes from a source you can trust.

•Currency Some pages have been on the Web for years without being updated. Look for the “last update” notation on the site’s front page. •Age-appropriate To learn about how the heart works, middle school students don’t need a lengthy article from a professional medical journal. Instead, find a well-illustrated article written at a lower level. •Acceptable mix of signal to noise Avoid too many distractions. Things such as ads, pop-up windows, and music that can’t be turned off soon become annoying. They detract from the value of the site.
