英译汉1. Li Na Li Na made history at the French Open on Saturday when she became the first Chinese player to win a grand slam singles title. Her 6-4, 7-6 victory over last year's champion, Francesca Schiavone of Italy, was a performance full of maturity, class and guts and when the pressure came late in the second set, she held firm.1 If this does not spark a new wave of Chinese players in the years to come then probably nothing will. An estimated audience of 65 million watched the final on television and online in China but the 29-year-old, who pocketed a cool will have to wait until after Wimbledon before she has time to fly home. "If I don't do well at Wimbledon maybe people will forget me already," she said. "But if a Chinese player can win a grand slam maybe it proves a lot for Chinese tennis. I believe Chinese tennis will get bigger and bigger." Having reached the final of the Australian Open in January, it looked as if Li's second opportunity for glory might be slipping away when, leading by a set and 4-2, she became tight.2 Perhaps it was the pressure of those watching at home, perhaps it was simply the occasion, but as she faltered, Schiavone moved to within two points of forcing it into a decider. But as the crowd roared for the Italian, Li showed her mettle and held firm. Twice she held serve to stay in the set and she then played a flawless tie-break3 to win in 7-0. As a Schiavone backhand drifted over the baseline, a disbelieving Li fell to the clay and put her hands to her face.4 "At 6-0 in the tie-break, I was thinking 'OK, don't do anything stupid,' because many times I have had match point and not won the match." she said. "When I was a young player, I wanted to be a grand slam champion and now I am. Someone said the other day that I'm getting old, so the old woman's dream has come true." Schiavone, whose victory last year was one of the most remarkable performances in Roland Garros history, embraced her opponent at the net and was equally kind-hearted afterwards. "Today was a really tough day but I have to congratulate Li Na because5 she's really grown up this year and she played really well. Enjoy this moment because5 it's fantastic." There is no histrionics, no climbing through the stands to greet her family and friends. Instead, Li sat calmly on her chair and let it all sink in. Though three Chinese pairs have tasted grand slam doubles glory before, she is the first to do it in singles. For a country of 1.3 billion, if only the tiniest fraction of the population pick up a racket rather than play another sport, the future will be bright.6

英译汉1. Modified Agricultural Practices Since agriculture accounts for nearly 70 percent of the world's fresh water withdrawn from rivers, lakes, and underground aquifers for human use, the greatest potential for conservation lies with increasing irrigation efficiency.1 By reducing irrigation by 10 percent, we could double the amount available for domestic water worldwide. This can be done by converting to water-conserving irrigation systems; taking the poorest and steepest lands out of production2; switching to less-thirsty crops (which may require changes to government subsidies for certain crops); implementing proper agricultural land drainage and soil management practices, and reducing fertilizer and pesticide use. Typically, governments provide water to large commercial farmers at greatly subsidized rates, decreasing the need for conservation and promoting wasteful practices3. This has led to widespread use of wasteful irrigation systems. Studies show that just 35-50 percent of water withdrawn for irrigated agriculture actually reaches the crops. Most soaks into the ground through unlined canals, leaks out of pipes, or evaporates before reaching fields. Although some of the water lost in inefficient irrigation systems returns to streams or aquifers where it can be tapped again, water quality is invariably degraded by pesticides, fertilizers and salts.4 This is in fact another way that commercial agriculture "uses" water: by polluting it so that it is no longer safe to drink. In areas where commercial agriculture is prevalent, runoff5 from farms has poisoned water supply with dangerous levels of toxics. Poorly planned and poorly built irrigation systems not only harm water quality, but can also irreparably6 harm the crop-growing capability of the land through salinization. Especially in arid areas, salts that occur naturally accumulate in irrigated soils. Poorly drained irrigation water can pollute water supply, and raise the groundwater table until it reaches the root zone, waterlogging and drowning crops. Globally, some 80 million hectares of farmland have been degraded by a combination of salinization and waterlogging. Switching to conserving irrigation systems has the biggest potential to save water used for agriculture (experts say drip irrigation could potentially save 40-60 percent of water now used for agriculture). The most common water-conserving irrigation systems are some form7 of drip irrigation (also called micro-irrigation). Conventional sprinklers spray water over crops, not only irrigating more land than is needed to grow the crop but also losing much8 to evaporation. Drip irrigation, however, supplies water directly to the crop's root system in small doses, where it can be used by the plant's roots. Water is delivered through emitters9 that drip water at each plant, or perforated piping, installed on the surface or below ground. This keeps evaporation losses low, at an efficiency rate of 95 percent. Although by 1991 some 1.6 million hectares were using drip irrigation worldwide, this is still less than one percent of all irrigated land worldwide. Some countries have made drip irrigation a serious national priority, such as Israel, which uses drip irrigation on 50 percent of its total irrigated area. But clearly it is the exception, and most dry countries have a long way to go.

英译汉10. The Supernote Kelly was stunned when the bills were presented to him. Two of them did not appear to be fraudulent. "I've done counterfeiting cases, and I know what a counterfeit bill looks like," he says. "These bills looked genuine. They felt genuine. I said, 'If these are counterfeit, this is a serious problem for the United States.'" Kelly immediately called the Boston office of the United States Secret Service, a branch of the Treasury.1 "I said, 'We have some outstanding-looking bills, and they came from Lebanon,'" he recalls. "Secret Service was at our door in three and a half minutes. They knew exactly what I was talking about.2" Kelly, it turned out, had obtained samples of a counterfeit3 hundred-dollar bill that had been dubbed the Supernote. It had surfaced around 1990 and originated in the Middle East, and, the agents told Kelly, as far as they could determine between two and three billion dollars' worth had been printed in two years. It was indeed no ordinary counterfeit. Most fake currency is printed on an offset press4—the type used for books and magazines—and it tends to look and feel flat. The Supernote, however, was being manufactured by the same industrial process used to make authentic United States currency, known as intaglio printing, in which an etched plate meets paper with tremendous force, giving the note a distinctive, embossed feel. The paper used for the Supernote was an uncanny replica of the currency stock produced exclusively for the United States government since 1879 by Crane Company of Dalton, Massachusetts—seventy-five percent cotton, twenty-five percent linen, with embedded red and blue fibres. The workmanship of the Supernote was extraordinary. It had sequential serial numbers, and the printing plates continued to be refined. A Secret Service agent identified Kelly's two samples as Supernotes by three minuscule imperfections. Even when the flaws were pointed out, Kelly says, "I frankly couldn't see the damn imperfections." (A former employee of the Secret Service's forensic division says that when a sample of the Supernote first arrived at the agency's5 laboratory, in Washington, a top technical analyst "examined it the way he has every other counterfeit note in the world, and called it genuine.") Most alarming of all, the Supernote was so well engineered that it could fool currency scanners at the nation's twelve Federal Reserve banks. The black ink on the front of American currency contains ferrous oxide, which is magnetic, and the Fed's scanners read the magnetic field down the center line of the portrait with such precision that a thousand genuine hundred-dollar bills are rejected for every one that is later found to be counterfeit. Yet, Kelly recalls, "Secret Service told me the bills went through those machines." The Supernote, Kelly learned, had been circulating in Europe, the Far East, the Middle East, and the former Soviet Union, but only a limited supply had reached the United States. This was not reassuring. Of the almost three hundred and ninety billion dollars in American paper money now in existence, some two-thirds, or more than two hundred and fifty billion, is in foreign hands. The worldwide popularity of the dollar is a tremendous boon to the United States. As the Federal Reserve is fond of pointing out, every bill in circulation is in effect an interest-free loan; an equivalent amount in government securities would cost the United States more than twenty-five billion dollars in annual interest payments. The beauty of bills stuffed in a mattress in Kazakhstan, for instance, is the good chance that the notes will never be called in. The Supernote was by no means the first foreign-made or foreign-distributed counterfeit of American currency, but because of its frightening and unprecedented quality it seemed singularly poised to damage world confidence in the dollar.

英译汉1. The World's Heaviest Drinking Countries1 People in the UK are among the most prolific drinkers in the world, according to a report released by the World Health Organization (WHO). Britons over the age of 15 on average drink 11.6 litres of pure alcohol a year, according to the "Global status report on alcohol and health 2014". The report provides country profiles for alcohol consumption in the 194 WHO member states, looking at the resulting impact on public health and policy responses. And it reveals that the harmful use of alcohol causes 3.3 million deaths a year worldwide.2 Europe is the region with the highest consumption of alcohol per person, making up the entire top 10. Belarus takes the top spot, with people on average drinking 17.5 litres of pure alcohol a year, followed by the Republic of Moldova where the figure is 16. 8 litres. Australia and Canada also have high levels of alcohol consumption, with people on average drinking 12.2 and 10.2 litres a year respectively. In the United States the figure is marginally lower at 9.2 litres. But in northern Africa and the Middle East, the average figure is less than 2.5 litres of alcohol per person, with many countries having figures below one litre. The average figure globally is 6.2 litres of pure alcohol per person per year. But as less than half the world population (38.3 per cent) actually drinks alcohol, this means that those who do drink consume on average 17 litres of pure alcohol annually, the report said. The WHO warned that alcohol consumption increases the risk of developing more than 200 diseases, including liver cirrhosis and some cancers. Dr. Oleg Chestnov, WHO assistant director-general for non-communicable diseases and mental health3, said: "More needs to be done to protect populations from the negative health consequences of alcohol consumption.4 "The report clearly shows that there is no room for complacency when it comes to reducing the harmful use of alcohol." The report also points out that a higher percentage of deaths among men than among women are from alcohol-related causes—7.6 percent of men's deaths and four per cent of women's deaths—though there is evidence that women may be more vulnerable to some alcohol-related health conditions compared to men. Dr. Shekhar Saxena, director for mental health and substance abuse at WHO, said. "We found that worldwide about 16 per cent of drinkers engage in heavy episodic drinking—often referred to as ' binge-drinking'—which is the most harmful to health. "Lower-income groups are more affected by the social and health consequences of alcohol. They often lack quality health care and are less protected by functional family or community networks. 5" The report also highlights the need for action by countries including national leadership to develop policies to reduce harmful use of alcohol, national awareness-raising activities and health services to deliver prevention and treatment services6, in particular increasing prevention, treatment and care for patients and their families, and supporting initiatives7 for screening and brief interventions. The figures represent the average amount of pure alcohol consumed per capita in each country between 2008 and 2010.

英译汉1. Biotech Crops Biotech crops bring higher yields with solid environmental benefits: less use of energy, better soil conservation, less fertilizer employed and therefore less polluting runoff into groundwater. But the voices opposed are also loud. Prof. Bruce Chassy, an American expert in the field, was recently in Beijing for an international conference; our journalist took the opportunity to interview him on the subject. Q: The people who denounce biotechnological crops say they are worried about the possibility of the alien genes in genetically modified crops spreading to other species. For example, suppose herbicide-tolerant cotton transmits its genes to weeds—then the weeds could become "superweeds". Do you think this concern is justified? A: Before a new biotech crop can be grown in the USA, it must be approved by the US Department of Agriculture and the Environmental Protection Agency. They require developers to provide evidence that there will be no unexpected or damaging environmental consequences if the crop is planted. The questions require an examination of the potential for gene flow and any consequences that would ensue, including issues such as superweeds and the impact on a variety of non-target species such as birds, butterflies, earthworms and frogs. Resistance to the herbicides used in conventional agriculture does occur from time to time, and there is no reason to believe that biotech crops will produce any different kind of herbicide-resistant weeds than we already see in agriculture. In fact, after six years of planting herbicide-resistant crops in the US, we have not seen the emergence of herbicide-resistant weeds. Q: In the US what percentage of people support biotech crops? And do those who support biotech crops also eat biotech crops? What percentage of food on the market has genetically modified ingredients? A: US consumers have been subjected to a very effective anti-biotechnology propaganda campaign for the last few years, but according to polls over 70% support biotechnology. For example, in a recent referendum in Oregon, voters rejected a proposal to require special labels on all products containing biotech ingredients by an overwhelming 73% to 27%. That's probably because consumers know that we have an effective regulatory system. Many may also know that 70% -80% of the processed food products on supermarket shelves contain one or more ingredients derived from biotech crops. All Americans eat biotech crops unless they deliberately seek out products that are labeled otherwise. Evidence suggests that this is less than 5% of consumers.
