That far (28) the old records. The magnitude of how unusual the year has been in

    18、the U.S. has alarmed some climate scientists who have (29) global warming. One climate scientist said its the weather equivalent of a baseball player on steroids, with old wiped out.“Everybody has this uneasy feeling. This is weird. This is not good,“ said Jerry Meehl, a climate scientist who (30) e

Youre out enjoying this nice March weather, but you know its not a good thing. “Its not just March. “Its been ongoing for several months,“ said Jake Crouch, a climate scientist at NOAAs Nationa

    20、l Climatic Data Center in Ashville, North Carolina.Climate scientists say an (32) confluence of several weather patterns, (33) La Nina, Was the direct cause of the warm start to 2012. While individual events cant be blamed on global warming, Crouch said this is like the extremes that (34) get more f

    21、requent because of man-made climate change from the burning of fossil fuels such as coal and oil. (35) March averages 42.5 degrees across the country. This year, the average was 51.1, which is closer to the average for April. Only one other time was the country as a whole that much hotter than norma

At a recent festival of pop-music in the Isle of Wight, crowds

    23、of teenagers (36) to listen to their favourite singers and musicians. They went with single railway tickets and slept in the open, a very (37) thing to do in the climate of Britain, even in August. They were (38) together like sardines (沙丁鱼) for four days. There were innumerable thieves; a gang of r

    24、oughs tried several times to break things up, and police were everywhere. At the end of the festival many young fans found themselves (39) , with no money left, and they had difficulty in getting back home. Most people would consider these conditions a (40) of discomfort; the fans appeared to enjoy

    25、it all (41) .Even in the overcrowded United Kingdom there are large tracts of open unspoiled country, where people with more (42) tastes can go for quiet, and for the sense of freedom they (43) from contact with nature. In the national parks especially, modem development of housing and industry is s

    26、trictly controlled. Visitors may walk for miles through landscape of the greatest beauty and wildness, and often of (44) historic or scientific interest. Along the coasts of some of the maritime (近海的) counties, public pathways have been created; these paths (45) for many miles along cliffs that look

    27、 out on the Atlantic Ocean or the English Channel. Another path, lying inland, goes along the range of mountains in the north of England. It is called the Pennine Way, Here, the long-distance walker and the nature-lover can find much to enjoy, without feeling disturbed by large numbers of their fell

    29、e U.S. Centers for Disease Control and Prevention released a stunning report on the impact of resistant bacteria. According to the analysis, which CDC officials said was conservative, more than 2 million people are infected in the United States each year by bacteria that are resistant to a wide arra

    30、y of the safest and most effective antibiotics. Of those, at least 23,000 die. The illnesses and deaths cost society some 55 billion annually-S20 billion from additional health-care spending and 35 billion from lost productivity. “If we are not careful, we will soon be in a post-antibiotic era,“ sai

    31、d Dr. Tom Frieden, the director of the CDC. “And for some patients and for some microbes, we are already there.“BResistant bacteria spread not only with cross-contamination from people who are already sick or unknowingly carrying the microbes; they also come from food Americans eat. Indeed, a curren

    32、t multistate outbreak of a multi-drug-resistant strain called Salmonella Heidelberg(海德堡沙门氏菌) was traced to Foster Farms brand chicken. As of October 11, the microbe had infected 317 people in 20 states and Puerto Rico; 133 of them required hospitalization.CIn the past, drug-resistant bacteria were r

    33、elatively easy to confront, with pharmaceutical (制药的) companies pumping out ever-more sophisticated antibiotics. Big Pharma isnt investing much time or effort in these lines of treatment these days-why commit hundreds of millions of dollars to research and develop a new antibiotic that will only be

    34、taken by a patient for a few days, when a breakthrough drug for, say, diabetes could be both unique and used by people for a lifetime?D“We have an increasing antimicrobial resistance across the world and we have a decreasing pipeline of new antibiotics,“ said Dr. Ed Septimus, a professor of internal

    35、 medicine at Texas AM Health Science Center and Medical Director for the Infection Prevention and Epidemiology Clinical Services Group at HCA Healthcare System. “It is a perfect storm in which, for some patients, it will feel like we are going back to the preantibiotic era.“ What would it be like li

    36、ving in a world without antibiotics? You can say goodbye to many lifesaving procedures we now consider commonplace.ETake heart transplants-they can be performed only because surgeons are confident the antibiotics they give patients before the procedure will prevent a postoperative infection. The sam

    37、e holds true for other complex surgeries. Chemotherapy (化疗) severely inhibits the immune system, which is why chemo patients require antibiotics. “So many of these medical miracles that we take for gianted are only possible because we have been able to deal with infectious complications,“ said Ruth

    38、Lynfield, the state epidemiologist and medical director at the Minnesota Department of Health. “If we cant do that, those areas of medicine-surgery, transplants, intensive care, neonatal care-could be lost. “FAnd it could be even worse. Several medical experts noted that while a virus caused the inf

    39、luenza pandemic of 1918, most of the tens of millions of people who perished from the disease died of a bacterial infection in the lungs. With effective antibiotics, that complication can be treated. Given the scarcity of viral vaccines in much of the world, if a resistant bacteria takes hold, all a

    40、nyone could do is find an effective way to dispose of the bodies. Given the stakes, it is astonishing to realize the causes of this threat are well-understood and the ways to attack it well-known. Even as far back as 1945, Alexander Fleming, a pioneer in antibiotics, said, “the misuse of penicillin(

    41、青霉素) could be the propagation of mutant forms of bacteria that would resist the new miracle drug.“GIn essence, this crisis is looming because the world consumes too many antibiotics. In the United States, doctors prescribe them too often, many times because patients demand them for illnesses that ar

    42、e not bacterial and thus cannot be treated with antibiotics, such as colds and other sicknesses caused by viruses. The CDC found that the greatest use of antibiotics for humans occurs in the Southern states, a fact that medical experts struggle to explain. One thing the data and studies indicate, th

    43、ough, is that the areas with the highest use are most likely to experience the most resistant bacteria.HBut the amount of antibiotics used by humans for medical purposes pales in comparison to the quantities fed to American livestock-pigs, cattle, and the like. According to the Food and Drug Adminis

    44、tration, about 80 percent of all antibiotics sold in 2011 were used on animals, primarily for spurring growth.IWhat makes the use of antibiotics for growth in meat and poultry production particularly troublesome, experts say, is the low dosages. Using small amounts of antibiotics is more likely to c

    45、reate resistant bugs, the experts said, because the microbes are not wiped out. Instead, the bacteria are essentially trained to resist the drugs. “It creates a reservoir of drug-resistant genes,“ said Dr. Henry Chambers, a professor of medicine at University of California San Francisco.JAntibiotics

    46、 are also used for animals in the United States as a prophylactic (预防品), to prevent infections likely to spread because of the meat and poultry production process. These so-called “production diseases“ are the result of a system which places ever larger numbers of animals into ever smaller containme

    47、nt areas, exposing them to each others feces, urine and-as a result-bacteria. “We need to change the animal production system, where animals are healthier and infections become the exception and not the norm,“ said Price. “We should prevent infections in animals by not overcrowding them, not packing

    48、 them in together and not exposing them to easy contamination.“KThe connection between antibiotic usage in animals and the development of resistant bacteria has long been recognized in Europe, which banned the use of the drugs as growth promoters in 2006. In the United States, the FDA only imposed vo
