Does a drink a day keep heart attacks away? Over the past 20 years, numerous studies have found that moderate alcohol consumption, s ay, one or two beers, glasses of wine or cocktails daily helps to prevent coronary heart disease. Last week a report in the New England Journal of Medicine added strong new evidence in suport of that theory. More important, the work provided the first solid indiction of how alcohol works to protect the heart.In the study, researchers from Boston’s Brigham and Women’s Hospital and Harvard Medical School compared the drinking habits of 340 men and women who had suffered recent heart attack with those of healthy people of the same age and sex. The scientists found that people who sip one to three drinks a day are about half as likely to suffer heart attacks as nondrinkers are. The apparent source of the protection: those who drank alcohol had higher blood levels of highdensity lipoproteins, the socalled good cholesterol, which is known to prevent heart disease.
As evidence has mounted, some doctors have begun recommending a daily drink for patients of heart diseases. But most physicians are not ready to reommend a regular happy hour for everyone. The risks of teetotalling(绝对戒酒) are nothing compared with the dangers of too much alcohol, including high blood pressure, strokes and liver troubles—not to mention violent behaviour and traffic accidents. Moreover, some studies suggest that even moderate drinking may increase the incidence of breast and colon cancer. Until there is evidence that the benefits of a daily dose of alcohol outweigh the risks, most people won’t be able to take a doctor’s prescription to the neighbourhood bar or liquor store.

A scientist who developed a way to calculate how much water is used in the production of anything from a cup of coffee to a hamburger was awarded the 2008 Stockholm Water Prize.
Professor John Anthony Allan of the University of London in Britain won the award for introducing the idea of “virtual water (虚拟水)”, a calculation method that has changed the nature of trade policy and research.
Allan has written seven books and published more than 100 papers.
The Stockholm International Water Institute said this idea is now embedded (埋藏) in the production of foods and industrial products. The institute said Allan’s work had made a big effect on global trade policy and research, especially in water-scarce (缺水的) regions.
“The improved understanding of trade and water management issues on local, regional and global scales are of the highest value for the successful and sustainable (可持续的) use of water resources,” it said.
“People do not only use water when they drink it or take a shower,” the institute said. “Behind the morning cup of coffee, there are 140 liters of water that was used to grow, produce, package and ship the beans.” That is about as much water as a person in England uses on average for all daily drinking and household needs.
“For a single hamburger, about 2,400 liters of water are needed. In the USA, the average person uses nearly 7,000 liters of virtual water every day.” It said that was more than three times the average use of a Chinese person.Allan was awarded the prize because _______.
| A．he wrote seven books on trade policy |
| B．he published more than 100 papers on water management |
| C．he found a new kind of water in water-scarce areas |
| D．he came up with the idea of virtual water |
Which of the following is TRUE according to the passage?
| A．The average American uses about 7,000 liters of water a day. |
| B．The average Chinese uses nearly 2,300 liters of virtual water a day. |
| C．An Englishman usually drinks about 140 liters of coffee a day. |
| D．A hamburger usually contains about 2,400 liters of water. |

Everyone knows that the French are romantic, the Italian are fashionable and the Germans are serious. Or do they? Are these just stereotypes or is there really such a thing as national character? And if there is, can it affect how a nation succeed or fail?
At least one group of people is certain that it can. A recent survey of the top 500 entrepreneurs (实业家) in the UK found that 70 percent felt that their efforts were not appreciated by the B
ritish public .
Britain is hostile to success, they said. It has a culture of jealousy (嫉妒) . As a result, the survey said, entrepreneurs were “unloved, unwanted and misunderstood”. Jealousy is sometimes known as the “green-eyed monster” and the UK is its home. Scientists at Warwich University in the UK recently tested this idea. They gathered a group of people together and gave each an imaginary amount of money. Some were given a little, others a great deal. Those given a little money were given the chance to destroy the large amounts of money given to others—but at the cost of losing their own. Two thirds of the people tested agreed to do this.
This seems to prove the entrepreneurs were right to complain. But there is also conflicting evidence. The Organization for Economic Cooperation and Development (OECD) recently reported that the UK was now the world’s fourth largest economy .That is not bad for people who are supposed to hate success. People in the UK also work longer hours than anyone else in Europe. So the British people are not lazy , either .
“It’s not really success that the British dislike,” says Carey Cooper, a Professor of management at the University of Manchester Institute of Science and Technology. “It’s people using their success in
a way that seems arrogant (傲慢) or unfair or which separates them from their roots .”
Perhaps it is the entrepreneurs who are the problem. They set out to do things in their way. They work long hours. By their own efforts they become millionaires. But instead of being happy they complain that nobody loves them. It hardly seems worth following their example. If they were more friendly, people would like them more. And more people want to be like them.What does the underlined “it” in the second paragraph refer to?
| A．One group of people | B．A great survey |
| C．National character | D．A nation |
Most entrepreneurs surveyed believe that
| A．they are not popular simply because they are successful |
| B．the British public are hardworking |
| C．love of success is Britain’s national character |
| D．they are considered as “green-eyed monsters” |
What does the result of the Warwich University test show?
| A．Two thirds of the people tested didn’t love money |
| B．Most people would rather fail than see others succeed |
| C．An imaginary amount of money does not attract people |
| D．Most people are willing to enjoy success with others |
The writer of the passage seems to suggest that .
A．Jealousy is Brit ain’s national character |
| B．British entrepreneurs are not fairly treated |
| C．the scientists are Warwich University did a successful test |
| D．the British dislike the entrepreneurs because they do not behave properly |
Work is a part of living —my grandparents understood that. They lived and worked on a farm that has been in my family for 150 years. They raised chickens for eggs , pigs and cattle for meat . Cows were kept for milk and the cream, from which Grandma made butter and cheese. What little yard they had became a garden.
The Depression, therefore, didn’t make much change in their lives. But it did bring an unending flow of men out of work, drifting from job to job, to the farm. The first to show up at the door of the kitchen was a man in rags. He took off his hat and quietly explained that he hadn’t eaten for a while. Grandpa stood watching him a bit , then said , “There’s a stack of firewood against the fence behind the barn (谷仓). I’ve been needing to get it moved to the other si
de of the fence . You have just about enough time to finish the job before lunch .”
Grandma said a surprising thing happened. The man got a shine in his eyes and he hurried to the barn at once. She set another place at the table and made an apple pie. During lunch, the stranger didn’t say much, but when he left, his shoulders had straightened. “Nothing ruins a man like losing his self-respect,” Grandpa later told me.
Soon after, another man showed up asking for a meal. This one was dressed in a suit and carried a small old suitcase. Grandpa came out when he heard voices. He looked at the man and then offered a handshake.” There is a stack of firewood along the fence down behind the barn I’ve been meaning to get it moved. It’d sure be a help to me . And we’d be pleased to have you stay for lunch.” The fellow set his suitcase aside and neatly laid his coat on top. Then he set off to work.
Grandma says she doesn’t remember how many strangers they shared a meal with during those Depression days-or how many times that stack of wood got moved.When he was asked to move a stack of firewood, the first man who asked for a meal got a shine in his eyes for he was glad that .
| A．he had found a good job |
| B．he would have something to eat |
| C．he would no longer suffer from the Depression |
| D．he would get what he wanted without losing his self-respect |
The writer’s grandfather asked those jobless men to move the stack of firewood because .
| A．he didn’t want them to have a meal free of charge |
| B．he had been needing to get it moved |
| C．he wanted to help them in his own way |
D．he wanted to show them his kindness and  respect |
The writer’s grandfather was all of the following but .
| A．kind | B．thoughtful | C．wealthy | D．sympathetic |
The best title for the story would be .
A．The Depression B．The Pleasure of Helping Others
C
．No Pains , No Gains D．Work-A Part of Living
Water problems in the future will become more intense and more complex. Our increasing population will tremendously increase urban wastes, primarily sewage. On the other hand, increasing demands for water will decrease substantially the amount of water available for diluting wastes. Rapidly expanding industries which inv
olve more and more complex chemical processes will produce larger volumes of liquid wastes, and many of these will contain chemicals which are noxious. To feed our rapidly expanding population, agriculture wil
l have to be intensified. This will involve ever - increasing quantities of agricultural chemicals. From this, it is apparent that drastic steps must be taken immediately to develop corrective measures for the pollution problem.
There are two ways by which this pollution problem can be dwindled(减少). The first relates to the treatment of wastes to decrease their pollution hazard . This involves the processing of solid wastes "prior to" disposal and the treatment of liquid wastes, or effluents, to permit the reuse of the water or minimize pollution upon final disposal .
A second approach is to develop an economic use for all or a part of the wastes. Farm manure is spread in fields as a nutrient or organic supplement. Effluents from sewage disposal plants are used in some areas both for irrigation and for the nutrients contained. Effluents from other processing plants may also be used as a supplemental source of water. Many industries, such as meat and poultry processing plants, are currently converting former waste products into marketable byproducts. Other industries are potential economic uses for waste products. The purpose of this passage is ________.
| A．to alert the reader to the dwindling water supply |
B．to explain industrial uses of water |
| C．to acquaint the reader with water pollution problems |
| D．to demonstrate various measures to solve the pollution problem |
Which of the following points is NOT included in the passage?
| A．Industrial development includes the simplification of complex chemical processes. |
| B．Diluting wastes needs certain amount of water. |
| C．Demands for water will go up along with the expanding population . |
| D．Intensive cultivation of land require more and more chemicals. |
The reader can conclude that _________.
| A．countries of the world will work together on pollution problems |
| B．byproducts from wastes lead to a more prosperous marketplace |
| C．science is making great progress in increasing water supplies |
| D．some industries are now making economic use of wastes |
The author gives substance to the passage through the use of________.
| A．interviews with authorities in the field of water controls |
| B．opinions and personal observations |
| C．definitions which clarify important terms |
| D．strong arguments and persuasions |
The underlined words "prior to"(para. 2)probably man________.
