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 away because they find it embarrassing to discuss their weight, smoking, 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—and most of them aren’t nearly sceptical 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’s hard to know if what you’re reading is reasonable or not，”says Dr．Sarah Bass from the National Cancer Institute．

PITTSBURGH—For most people, snakes seem unpleasant or even threatening．But Howie Choset sees in their delicate movements a way to save lives．

The 37-year-old Carnegie Mellon University professor has spent years developing snake-like robots he hopes will eventually slide through fallen buildings in search of victims trapped after natural disasters．

Dan Kara is president of Robotics Trends, a Northboro, Mass-based company that publishes an online industry magazine and runs robotics trade shows．He said there are other snake-like robots being developed, mainly at universities, but didn’t know of one that could climb pipes．

The Carnegie Mellon machines are designed to carry cameras and electronic sensors and can be controlled with a joystick（操纵杆）．They move smoothly with the help of small electric motors, or servos, commonly used by hobbyists in model airplanes．

Built from lightweight materials, the robots are about the size of human arm or smaller．They can sense which way is up, but are only as good as their human operators, Choset added．

Sam Stover, a search team manager with the Federal Emergency Management Agency based in Indiana, said snake-type robots would offer greater mobility than equipment currently available, such as cameras attached to extendable poles．

“It just allows us to do something we’ve not been able to do before．”Stover said,“We needed them yesterday．”

He said sniffer dogs are still the best search tool for rescue workers．but that they can only be used effectively when workers have access to damaged buildings．

Stover, among the rescue workers who handled the aftermatch（后果）of Hurricane Katrina, said snake robots would have helped rescuers search flooded houses in that disaster．

Choset said the robots may not be ready for use for another five to ten years．depending on funding．

1．Which institution is responsible for the development of Choset’s robots?

       A．Robotics Trends．

       B．Pittsburgh City Council．

       C．Carnegie Mellon University．

       D．Federal Emergency Management Agency．

2．Choset believes that his invention          ．

       A．can be attached to an electronic arm

       B．can be used by hobbyists in model airplanes

       C．can find victims more quickly than a sniffer dog

       D．can sense its way no better than it operators

3．By saying “We needed them yesterday”（paragraph 7）, Stover means that snake-like robots         ．

       A．could help handle the aftermath of Hurricane Katrina

       B．would have been put to use in past rescue work

       C．helped rescuers search flooded houses yesterday

       D．were in greater need yesterday than today

4．What is the text mainly about?

       A．Snake-like robots used in industries．

       B．Snake-like robots made to aid in rescues．

       C．The development of snake-like robots．

       D．The working principles of snake-like robots．
