13．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 normal symptoms（癥狀） are the most obvious example．Increasingly，however，remote diagnosis（遠程診斷） will be based on real physiological data（生理數(shù)據(jù)） 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 equipment，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（寬帶） is the limiting factor for sending complex（復(fù)雜的） medical pictures around the world-CT photos being one of the biggest bandwidth users．Communication satellites may 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．
59．The writer chiefly talks aboutA
A．the use of telemedicine                 
B．the on-lined doctors
C．medical care and treatment        
D．communication improvement
60．The basis of remote diagnosis will beC．
A．personal data assistance 
B．some words of a patient
C．real physiological information
D．medical pictures from the Internet
61．Which of the following statements is true according to the text？D
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．
62．The"problem"in the fourth paragraph refers to the fact thatA．
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．

14．Facebook is the world's biggest social networkingsite．People are being tricked into Facebook with the promise of a fun，freeservice without realizing they're paying for it by giving up loads of personal information．
Most Facebook users don't realize this is happening．Even if they know what the company is up to，they still have no idea what they're paying for Facebook because people don't really know what their personal data is worth．
The biggest problem，however，is that the company keeps changing the rules．Early you could keep everything private．That was the greatthing about Facebook-You could create your own little private network．Last year，the company changed its privacy rules so that many things-your city，your photo，your friends'names-were set，by default （默認），to be shared with everyone on the Internet．
According to Facebook's vice-president Elliot Schrage，the company is simply making changes to improve its service，and if people don't share information，they have a"less satisfying experience"．
Some critics（批評家） think this is more about Facebook looking to make more money．In original business model，which involved selling ads and putting them in the side of the pages totally，who wants to look at ads when they're online connecting with their friends？
The privacy issue has already landed Facebook in hot water in Washington．In April，Senator Charles Schumer called on Facebook to change its privacy policy．He also urged（催促） the Federal Trade Commission to set guidelines for social networking sites．"I think the senator rightly communicated that we had not been clear about what the new products were and how people could choose to use them or not to use them，"Schrage admits．
I suspect that whatever Facebook has done so far to invade our privacy，it's only the beginning，which is why I'm considering cancelling（取消）my account．Facebook is a handy site，but I'm upset by the idea that my information is in the hands of people I don't know．That's too high a price to pay．
28．What do we learn about Facebook from the first paragraph？D
A．It is a website that sends messages to users who want to get married
B．It earns money by putting on advertisements
C．It provides loads of personal information to its users
D．It makes money by selling its users'personal data
29．What does the author say about most Facebook users？D
A．They are unwilling to give up their personal information
B．They care very little about their personal information
C．They don't identify themselves when using the website
D．They don't know their personal data enriches Facebook
30．Why does Facebook make changes to its rules according to Elliot Schrage？B
A．To obey the Federal guidelines
B．To provide better service to its users
C．To improve its users'connection
D．To expand its business
31．Why does the author plan to cancel his Facebook account？A
A．He doesn't want his personal data badly used
B．He finds many of its users untrustworthy
C．He is dissatisfied with its present service
D．He is upset by its frequent rule changes．
