Passage 2

　　Want a glimpse of the future of health care? Take a look at the way the various networks of people involved in patient care are being connected to one another, and how this new connectivity is being exp1oited to deliver medicine to the patient -- no matter where he or she may be.

　　Online doctors offering advice based on standardized symptoms are the most obvious example. Increasingly, however, remote diagnosis (telemedicine) will be based on real physiological data from the actual patient. A group from the University of Kentucky has shown that by using an off--the-shelf (现成的) PDA (personal data assistance) such as a Palm Pilot plus a mobile phone, it is perfectly feasible to transmit a patient’s vital signs over the telephone. With this kind of equipment in a first-aid kit (急救包), the cry asking whether there was a doctor in the house cou1d well be a thing of the past.

　　Other medical technology groups are working on applying telemedicine to rural care. And at least one team wants to use telemedicine as a tool for disaster response -especially after earthquakes. Overall, the trend is towards providing global access to medical data and expertise.

　　But there is one problem. Bandwidth is the limiting factor for transmitting complex medical images around the world - CT scans being one of the biggest bandwidth consumers. Communications satellites may be able to cope with the short-term needs during disasters such as earthquakes, wars or famines. But medicine is looking towards both the second-generation Internet and third-generation mobile phones for the future of distributed medical intelligence.

　　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 usher in（迎来）an era when telemedicine and the sharing of medical information, expert opinion and diagnosis are common.

　　51. The basis of remote diagnosis will be ______.

　　A. standardized symptoms of a patient           B. personal data assistance

　　C. transmitted complex medical images          D. real physiological data from a patient

　　52. The sentence "the cry asking whether there was a doctor in the house could well be a thing of the past" means ______.

　　A. now people probably would not ask if there is a doctor in the house

　　B. patients used to cry and ask if there was a doctor in the house

　　C. in the past people often cried and asked if there was a doctor in the house

　　D. patients are now still asking if there is a doctor in the house

　　53. All the following statements are true EXCEPT that ______.

　　A. it is now feasible to transmit a patient's vital signs over telephone

　　B. flood is not among the disasters mentioned in the passage

　　C. the trend in applying telemedicine is toward providing global access to medical data

　　D. telemedicine is being used by many medical teams as a tool for disaster response

　　54. The word "problem" in the fourth paragraph refers to the fact that ______.

　　A. there are not enough mobile phones for distributing medical intelligence

　　B. CT scans are one of the biggest bandwidth consumers

　　C. bandwidth is not adequate to transmit complex medical images around the world

　　D. communications satellites can only cope with the short-term needs during disasters

　　55. A proper title for the passage may be ______.

　　A. Improvement in Communications               B. The Online Doctor Is In

　　C. Application of Telemedicine                       D. How to Make Remote Diagnosis
