Want a glance of the future of health care? Take a look at the way the various networks of people about patient care are being connected to one another, and how this new connectivity is being exploited to deliver medicine to the patient - no matter where he or she may be.
Online doctors offering advice based on norman symptoms(症状)are the most obvious example. Increasingly, however, remote diagnosis(远程诊断)will be based on real physiological data(生理数据)from the actual patient. A group from the University of Kentucky has shown that by using personal data assistance plus a mobile phone ,it is perfectly practical to send a patient’s important signs over the telephone. With this kind of equipement, the cry asking whether there was a doctor in the house could well be a thing of the past.
Other medical technology groups are working on applying telemedicine to rural (countryside) care. And at least one team wants to use telemedicine as a tool for disaster need - especially after earthquakes. On the whole, the trend is towards providing global access to medical data and experts’ opinions.
But there is one problem. Bandwidth(宽带) is the limiting factor for sending complex (复 杂 )medical pictures around the world,—CU photos being one of the biggest bandwidth users. Communication satellites say be able to deal with the short - term needs during disasters such as earthquakes or wars. But medicine is looking towards both the second - generation Internet and third generation mobile phones for the future of remote medical service.
Doctors have met to discuss computer - based tools for medical diagnosis, training and telemedicine. With the falling price of broadband communications, the new technologies should start a new time when telemedicine and the sharing of medical information, experts’opinions and diagnosis are common.
The writer chiefly talks about ________ .
A. the use of telemedicine
B. the on -lined doctors
C. medical care and treatment
D. communication improvement
Which of the following statements is true according to the text?
A. Patients don’t need doctors in hospitals any more.
B. It is impossible to send a patient’s signs over the telephone.
C. Many teams use telemedicine dealing with disasters now.
D. Broadband communications will become cheaper in the future.
The“problem”in the fourth paragraph refers to the fact that ________ .
A. bandwidth isn’t big enough to send complex medical pictures
B. the second - generation of Internet has not become popular yet
C. communication satellites can only deal with short - term needs
D. there is not enough equipment for spreading the medical care

查看习题详情和答案>>Thirty-two people watched kitty Genovese being killed right beneath their windows. She was their neighbor. Yet none of the 32 helped her. Not one even called the police. Was this in gunman cruelty? Was it lack of feeling about one’s fellow man?
Not so, say scientists John Barley and Bib Fatane. These men went beyond the headlines to probe(探查) the reasons why people didn’t act. They found that a person has to go through two steps before he can help. First he has to notice that is an emergency(紧急情况).
Suppose you see a middle-aged man fall to the side-walk. Is he having a heart attack? Is he in a coma (昏迷) from diabetes(糖尿病)? Or is he about to sleep off a drunk?
Is the smoke coming into the room from a leak in the air conditioning? Is it steam pipes? Or is it really smoke from a fire? It’s not always easy to tell if you are faced with a real emergency.
Second, and more important, the person faced with an emergency must feel personally responsible. He must feel that he must help, or the person won’t get the help he needs.
The researchers found that a lot depends on how many people are around. They had college students in to be tested. Some came alone. Some came with one or two others. And some came in large groups. The receptionist started them off on the tests. Then she went into the next room. A curtain divided the testing room and the room into which she went. Soon the students heard a scream, the noise of file cabinets falling and a cry for help. All of this had been pre-recorded on a tape-recorder.
Eight out of ten of the students taking the test alone acted to help. Of the students in pairs, only two out of ten helped. Of the students in groups, none helped.
In other words, in a group, Americans often fail to act. They feel that others will act. They, themselves, needn’t. They do not feel any direct responsibility.
Are people bothered by situations where people are in trouble? Yes. Scientists found that the people were emotional, they sweated, they had trembling hands. They felt the other person’s trouble. But they did not act. They were in a group. Their actions were shaped by the actions of those they were with.
