6、Increasingly, Americans are becoming their own
doctors, by going online to diagnose their symptoms, order home health tests or
medical devices, or even self-treat their illnesses with drugs from Internet
pharmacies(药店). Some avoid doctors because of the high
cost of medical care, especially if they lack health insurance. Or they may
stay because they find it embarrassing to discuss their weight, alcohol
consumption or couch potato habits. Patients may also fear what they might
learn about their health, or they distrust physicians because of negative
experiences in the past. But playing doctor can also be a deadly game.
Every day, more than six million Americans turn to the
Internet for medical answers - most of them aren’t
nearly skeptical enough of what they find. A 2002 survey by the Pew Internet
& American Life Project found that 72 percent of those surveyed believe all
or most of what they read on health websites. They shouldn’t. Look up “headache”, and the chances of finding reliable and complete information, free
from a motivation for commercial gain, are only one in ten, reports an April
2005 Brown Medical School study. Of the 169 websites the researchers rated,
only 16 scored as “high quality”. Recent studies found faulty facts about all sorts of other
disorders, causing one research team to warn that a large amount of incomplete,
inaccurate and even dangerous information exists on the Internet.
The problem is most people don’t know the safe way to surf the Web. “They use a search engine like Google, get 18 trillion choices and start clicking. But that’s risky, because almost anybody can put up a site that looks authoritative(权威的), so it’d hard to know if what you’re reading is reasonable or not,” says Dr. Sarah Bass from the National Cancer Institute.
1. According to the text, an increasing number of American _____.
