题目内容
| A．Governments should regulate the real value of water． B．Measures should be taken to centralize the management of water resources． C．It’s advisable to build small and cheap irrigation systems in some hot and dry areas． D．Humanity hasn’t placed efficient value on water resources． E．The world population is increasing faster and faster． F．The water problem is already serious in certain parts of the world． |
1．_______
Humanity uses a little less than half the water available worldwide．Yet occurrences of shortages and droughts are causing famine and distress in some areas, and industrial and agricultural by-products are polluting water supplies．Since the world’s population is expected to double in the next 50 years, many experts think we are on the edge of a widespread water crisis．
2．_______
But that doesn’t have to be the outcome．Water shortages do not have to trouble the world----if we start valuing water more than we have in the past．Just as we began to appreciate petroleum more after the 1970s oil crisis, today we must start looking at water from a fresh economic perspective．We can no longer afford to consider water a virtually free resource of which we can use as much as we like in any way we want．
3．_______
Instead, for all uses except the domestic demand of the poor, governments should price water to reflect its actual value．This means charging a fee for the water itself as well as for the supply costs．
4．_______
Governments should also protect this resource by providing water in more economically and environmentally sound ways．For example, often the cheapest way to provide irrigation water in the dry tropics is through small-scale projects, such as gathering rainfall in depressions（凹地） and pumping it to nearby cropland．
5．________
No matter what steps governments take to provide water more efficiently, they must change their institutional and legal approaches to water use．Rather than spread control among hundreds of even thousands of local, regional, and national agencies that watch various aspects of water use, countries should set up central authorities to coordinate water policy．

欣语文化快乐暑假沈阳出版社系列答案When people talk of a virus these days, chances are that they are talking about computer virus that have the power wipe out all the valuable work people may have stored in their computers. Imagine, the virus has the power to make military systems, giant banks, airports, hospitals and traffic system come to stop!
What does a computer virus do? It targets electronic objects that are programmed. The virus spreads through connections between these electronic objects. For virus spreading experts, e-mail is a favorite method of sending their destructive (破坏性的) weapon.
But scientists warn that this is not the worst that can happen. There is more. People are also connected through phones. The next virus may actually target mobile phones, especially those that are programmed to do many tasks apart from just communicating. It would then be easy for a virus to infect those programs and create major disorder.
For example, these virus may have the power to record your phone conversations and make others hear them. They create problems with your electronic money accounts, or they could create a mountain of telephone bills for calls you never made. And that would be a disaster. A report on this was published in the New Scientist recently.
One way out would be to have simpler phones with not so many different functions. This would mean there would mean there would be fewer programs for the virus to attack. But mobile phone producers are in a fix. People on longer want an electronic item to perform just one task. They want more and more functions added. That would mean more software programs to make the mobile phone perform all those functions. And that means the possibility of more viruses.

| B．people should be careful when receiving e-mails |

| A．Mobile phone producers have made no progress. |
| B．Mobile phone producers are proud of their products. |
| C．Mobile phone producers are faced with a difficult situation. |
| D．Mobile phone producers refused to fight against virus. |
| A．Government officials | B．Virus spreading experts |
| C．Electronic scientists | D．Mobile phone users |
Self-employed private physicians who charge a fee for each patient visit are the foundation of medical practice in the United States. Most physicians have a contract relationship with one or more hospitals in the community. They send their patients to this hospital, which usually charges patients according to the number of days they stay and the facilities(operating room, tests, medicines that they use). Some hospitals belong to a city, a state or, in the case of veteran's hospitals, a federal government agency. Others are operated by religious orders(教会) or other non-profit groups.
Some medical doctors are on salary. Salaried physicians may work as hospital staff members, or residents, who are often still in training. They may teach in medical schools, be hired by corporations to care for their workers or work for the federal government's Public Health Service.
Physicians are among the best paid professionals in the United States. In the 1980s, it was not uncommon for medical doctors to earn incomes of more than $ 100 000 a year. Specialists, particularly surgeons, might earn several times that amount. Physicians list many reasons why they deserve to be so well rewarded for their work. One reason is the long and expensive preparation required to become a physician in the United States. Most would-be physicians first attend college for four years, which can cost nearly $ 20 000 a year at one of the best private institutions. Prospective physicians then attend medical school for four years. Tuition alone can exceed $ 10 000 a year. By the time they have obtained their medical degrees, many young physicians are deeply in debt. They still face three to five years of residency(实习阶段) in a hospital, the first year as an apprentice physician. The hours are long and the pay is relatively low.
Setting up a medical practice is expensive, too. Sometimes several physicians will decide to establish a group practice, so they can share the expense of maintaining an office and buying equipment. These physicians also take care of each other's patients in emergencies.
Physicians work long hours and must accept a great deal of responsibility. Many medical procedures, even quite routine ones, involve risk. It is understandable that physicians want to be well rewarded for making decisions which can mean the difference between life and death.

| B．It is reasonable for physicians to have a large income because their work is very dangerous. |
| C．Physicians should be better paid because they work long hours under bad conditions. |
| D．Physicians have great responsibility, so it is understandable that they should be well rewarded. |
