     Increasingly, Americans are becoming their own doctors, by going online to diagnose(诊断) 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 medical care(忧虑),

especially if they lack health insurance(保险). Or they may stay because they find it embarrassing to

discuss their weight, alcohol consumption(消耗) or couch(睡椅) 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 American thru to the Internet for medical answers-most of

them aren't nearly skeptical(怀疑的) 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 warm that a large amount of incomplete, inaccurate(错误的) and even dangerous

information exists on the Internet.

     The problem is that most people don't know the safe way to surf the web. "They use a search

engine(工具) like Google, get 18 trillion choices and start clicking. But that's risky, because almost

anybody can put up a site that looks authoritative (有权威的), so it's hard to know whether what

you're reading is reasonable or not," says Dr. Sarah Bass from the National Cancer Institute.
