听力原文： No one is sure how many Americans belong to reading groups called book clubs. Yet publishers and bookstores report that more and more people throughout the United States are joining them.
(32)Most of the clubs work the same way. Members read the same book at the same time. Then they meet to talk about the book. Members may be friends or people who live near each other. Or, they may be people who work together. Some book clubs develop from other organizations. Religious and community groups often establish book clubs. Some Americans belong to reading groups on the computer service known as the Internet. These groups include people around the world who communicate about books they read. (33)These people send electronic mail instead of meeting to discuss books. Book clubs may be for only women or only men. Or, they can be for husbands and wives together. Some are family groups where parents attend with their children. Children may belong to book clubs of their own. (34)Most reading groups study books by a number of writers. However, some groups read the work of a single writer, usually one that has been famous for a while. (35) Other groups may be named for an important person in the work of the write, like a Sherlock Holmes Club. Holmes is the great British crime investigator created by Sir Arthur Conan Doyle. Members of these book clubs often are experts about their chosen reading materials. For example, one member of a Holmes reading group can identify almost every person in every Sherlock Holmes story.

Online doctors offering advice based on normal symptoms are the most obvious example. Increasingly, however, remote diagnosis will be based on real physiological data 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 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 is the limiting factor for sending complex 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.
The writer chiefly talks about ______.
A．the use of telemedicine
B．the on-line doctors
C．medical care and treatment
D．communication improvement

Food and Cancer
Medical Experts have suspected for many years that there is a strong link between what a person eats and cancer. They say a new study provides the first evidence that vitamins could reduce a person's chance of developing cancer. A team of Chinese and American scientists did the study. They are from American National Cancer Institute and the Cancer Institute of the Chinese Academy of Medical sciences in Beijing. The Journal of the National Cancer Institute published the results of the study. About thirty thousand people between the ages of 40 to 69 took part in the study. They were form. the northern central Chinese area of Linxian. Most of them took vitamins and minerals every day for five years.
Linxian was chosen because the people there have an extremely high rate of cancer of stomach and esophagus. Researchers believe that fungus and molds in local foods may be partly responsible for the high cancer rate. Researchers divided those into eight groups. Seven of the groups received different mixtures of vitamins and minerals daily. The amounts of the vitamins and minerals were 1 to 2 times greater than what American health officials say is needed. The eighth group received sugar pills that had no effect. Those who seemed to fain the most received a mixture of a form. of vitamin A called B-carotene, vitamin E and the mineral selenium. The vitamin and mineral are believed to prevent damage to cells caused by cancer-causing substances. Researchers reported a 13 percent drop in cancer rates in those who took B-carotene, vitamin E and selenium. They also found a 10 percent drop in the number of deaths caused by strokes from bursting blood vessels.
Scientists warn that it is too soon to know if the effect, would be the same among people in other countries. They note that the people in Linxian eat foods that lack necessary vitamins and minerals. Chinese officials will continue to record the health records of the people in Linxian for many years. For now officials reportedly are considering using the results of the study. They want to find a way to improved the health of people in Linxian and other small towns in China.
The results of the new study are unexpected.
A．Right
B．Wrong
C．Not Mentioned

听力原文： Scientists in many developing nations are studying a way to protect and control the use of forests, fishing water, grasslands and other resources. They call the system "common property". It means that people join together to abate and protect the resources. Scientists say that increased population is damaging the world resources. Too many trees are cut; grasslands and croplands are destroyed. Too many fish are taken from the fishing area. There are two traditional ways to deal with this situation. One is public: the government agency decides who may use the resources and when; or the property can be private: the owner decides how to protect the resources. Experts say these two methods often are not effective, however. They believe there is a third possibility that is neither completely governmental nor completely private. It is communal or joint control of the resources.
Scientists know that this idea of common property is not new. The system has been believed successful for a long time by groups in many countries. In South Asia, some villagers have governing systems to protect everyone's right to irrigation water. In part of Central Africa, there are traditional rules that banned the killing of some wild animals. Farmers in Syria have a system to share grasslands and fisherman in Turkey have a system to make sure no one takes too many fish. Scientists say such systems usually were developed by small groups to deal with limited problems. Rules are simple and the enforcement is based on traditional value and ways of doing things. Scientists believe such systems also would be effective in other situations. They are studying how it might produce more cooking rules for people in Indian villages. The scientific group in Costa Rice is studying common property to control land area. And a government group in Zimbabwe is studying the system to protect wild animals. Scientists do not say the common property system will solve all resource needs in developing nations, buy they believe it provides one important way to deal with the problem.

A．Property owned by a group of people.
B．Privately-owned property.
C．Government-owned property.
D．People's joint effort to share and protect natural resources.
