A deadly strain of avian flu may have passed between people for the first time,
题型：不详难度：来源：
The findings provide the strongest evidence yet of H7N9 transmission between humans since its discover in February, but its ability to transmit itself was deemed "limited and non-sustainable" by the Chinese researchers behind the study.At the end of June 133 cases had been reported, including 43 deaths. Most infections have been among people visiting markets, selling live birds or among those who had contact with live poultry（家禽） in the seven to 10 days before becoming ill.
The latest study examined the case of a 60-year-old father who regularly visited a live poultry market and became ill five to six days after his last visit in March. He was admitted to hospital with fever, cough and shortness of breath. Despite intensive care treatment he died of multiple organ failure on 4 May. His 32-year-old daughter, who was previously healthy, looked after him at his bedside before he was admitted to intensive care. She had no known exposure to live poultry before falling ill with a very high temperature, cough and fever. The daughter developed symptoms six days after her last contact with her father and was admitted to hospital where she died of multiple organ failure on 24 April.
Follow-up investigations(调查) uncovered almost genetically identical virus strains from each patient, suggesting transmission from father to daughter. Another 43 people were also tested who had had close contact with the father, daughter or both.
Dr Peter Horby, senior clinical research fellow at the Oxford University Clinical Research Unit in Hanoi, Vietnam, said of the study: "The most likely source of infection for the daughter was her father, during the period that she cared for him while he was ill. "He said “limited person to person transmission had been reported for other strains like H5N1 , H7N7, and the pig origin flu virus H3N2. Those strains had been around for more than a decade but have not progressed any further down the path towards a world-wide virus.” “Limited human-to-human transmission of H7N9 virus is therefore not surprising, but strengthening to monitor it was still needed,” Dr Horby added.

小题4:B
小题5:D
解析
试题分析：本文是一篇关于H7N9禽流感在人际间传播的一篇报道。研究人员通过对因患H7N9禽流感而死亡的一对父女的病例研究认为H7N9禽流感存在人与人之间传播的可能，但是指出H7N9禽流感这种人传人的效力很低，公众没有必要恐慌。
小题1:B主旨大意题。本文为科学研究类文章，开头亮明主题，本文首句A deadly strain of avian flu may have passed between people for the first time, experts believe。然后围绕这一话题叙述具体研究过程和发现，所以文章中心是：(H7N9) virus可能在人与人之间传播。故B选项正确。
小题2:C推理判断题。从文章最后一段The most likely source of infection for the daughter was her father, during the period that she cared for him while he was ill.可知32岁的女儿没有接触过活禽，但是在照顾父亲六天后出现发烧等禽流感症状。所以她死亡的病因是和患禽流感的父亲的密切接触。故C选项正确。
小题3:D细节理解题。从末段Those strains had been around for more than a decade but have not progressed any further down the path towards a world-wide virus.”可知目前H7N9禽流感病毒大规模人传人可能性不大。所以D选项正确。
小题4:B词义猜测题。A被减少；B被认为；C被想起；D被发展。"limited and non-sustainable" 是H7N9病毒的特点，根据语境此处应该是指研究人员认为H7N9病毒传播的能力是有限的，非持续性的。故B选项正确。
小题5:D推理判断题。从文章内容我们可知这是一篇关于H7N9流感病毒的报道，所以文章应该属于医学发现类文章。所以D选项正确。

On January 15th 2013 food inspectors discovered 30 % horsemeat in a certain brand of frozen beefburgers that were mostly sold by Tesco in the UK and Ireland.
In times of social media like Facebook and Twitter the news has spread fast and customers have been very concerned about what the food they buy actually contains. Tesco said it had taken away the burgers from the shop shelves immediately, and apologized to their customers. They also promised that they would find out what exactly happened and that they would work harder than ever so this would never happen again. Customers are also able to return the beefburgers and get a refund, that is, their money back.
However, it will be hard for Tesco to get the people’s trust back. Just imagine buying lovely beefburgers that you fry at home and suddenly you find out that you have actually eaten horsemeat! In this case not only horse lovers will be upset!
By the way, why are British people so shocked about eating horsemeat? In history, horses have played great roles as working animals and as an important means of transport. When Britons of today think of horses, they think of majestic animals or cute pets rather than meat.
But this is not the only reason for the protest: Customers also want to be sure that the products they buy contain what it says on the label. Hopefully, supermarkets can avoid mistakes like that in the future. Maybe there should be stricter regulations and more controls of our food? Otherwise we will soon find ourselves eating panda meat instead of pork and parrot instead of chicken. So the next time you are in a supermarket maybe check the ingredients of your food before you buy it or you could get a nasty surprise …

| A．Tesco’s products were much more expensive than they are supposed to be. |
| B．Tesco didn’t react immediately to a food quality issue. |
| C．Tesco sold expired food. |
| D．Horsemeat was found in burgers sold in Tesco. |
| A．It withdrew the beefburgers. |
| B．It made an apology to the public. |
| C．It investigated and found out the cause and effect of the scandal. |
| D．It returned money to customers who bought the beefburgers. |
| A．People trusted Tesco so much that they never expected a scandal like this. |
| B．Everyone can call himself or herself a horse lover in the UK. |
| C．Sellers shouldn’t cheat customers. |
| D．The horse is humans’ friend. |
After a month of feeling upset, Thomas decided he’d better find a way to fight back．He left Canton, Michigan for New York, got a job waiting tables, nicknamed himself the Diabetic Rockstar, and created diabeticrockstar.com, a free online community for diabetics(糖尿病患者) and their loved ones ---- a place where over 1,100 people share personal stories, information, and resources．
Jason Swencki’s son, Kody, was diagnosed with type diabetes at six．Father and son visit the online children’s forums（论坛） together most evenings．“Kody gets so excited, writing to kids from all over,” says Swencki, one of the site’s volunteers. “They know what he’s going through, so he doesn"t feel alone.”
Kody is anything but alone. Diabetes is now the seventh leading cause of death in the United States, with 24 million diagnosed cases．And more people are being diagnosed at younger ages．
These days, Thomas’s main focus is his charity, Fight It, which provides medicines and supplies to people ---- 225 to date ---- who can’t afford a diabetic’s huge expenses．Fight-it org has raised about $23,000 ---- in products and in cash．In May, Thomas will hold the first annual Diabetic Rockstar Festival in the Caribbean．
Even with a staff of 22 volunteers, Thomas often devotes up to 50 hours a week to his cause, while still doing his full-time job waiting tables．“Of the diabetes charities out there, most are putting money into finding a cure,” says Bentley Gubar, one of Rockstar’s original members. “But Christopher is the only person I know saying people need help now.”

The islands in dispute are called the Senkaku chain by Japan, the Diaoyu islands by China, and the Diaoyutai by Taiwan. All three claim the islands, which are really just five small islands and three barren rocks northeast of Taiwan, 200 miles off the Chinese coast.
The latest conflict occurred when a Chinese fishing boat collided(碰撞) with two Japanese naval ships trying to stop it near the islands. The Japanese prevented the Chinese captain from leaving the place for questioning and the two countries have been exchanging angry protests.
The reason to worry is that nationalists in both China and Taiwan see the islands as unquestionably theirs and think that their government has been weak in claiming this authority.
So far, wiser heads have generally won the argument on each side, but at some point a weakened Chinese leader might try to gain the legal right with the public by pushing the issue and recovering the islands. It would be a dangerous game and would have a disastrous impact on China-Japan relations, but if successful it would raise the popularity of the Chinese government.
In reality, of course, there is zero chance that the U.S. will honor its treaty(条约) with Japan over a few barren rocks. We"re not going to risk a nuclear conflict with China over some islands that may well be China"s. But if we don"t help, our security relationship with Japan will be at the breaking point.
So which country has a better claim to the islands? My feeling is that it"s China, although the answer isn"t clear-cut. Chinese navigational records show the islands as Chinese for many centuries, and a 1783 Japanese map shows them as Chinese as well. Japan purported to “discover” the islands only in 1884 and took control of them by force only in 1895 when it also grabbed Taiwan.
The best approach would be for China and Japan to agree to refer the dispute to the International Court of Justice, but realistically that won"t happen. And since some believe that the area is rich with oil and gas reserves, the claims from each side have become more insistent.
As Chinese nationalism grows, as China"s navy and ability to project power in the ocean gains, we could see some military conflicts over the islands.

A polar bear"s dead body found on the Arctic island of Svalbard, the northernmost part of Norway, has shocked experts who say climate change may be to blame for the animal’s death.The starved polar bear in Norway was said to be in good health in April when the Norwegian Polar Institute examined and labeled it． However, the animal was reduced to skin and bones by the time a group of explorers came across its body in July．
The bear is thought to have been heading north in a desperate search for sea ice that would allow it to hunt for seals.
"From his lying position in death the bear appears to simply have starved and died where he dropped," polar bear expert Dr. Ian Stirling, a professor at the University of Alberta said, "He had external suggestion of any remaining fat, having been reduced to little more than skin and bone．"
Stirling believes the bear starved to death as a result of a lack of sea ice which the animals use as a platform for hunting seals． That may also explain why the 16-year-old male bear was found about 155 miles north of where it was seen in April．
Arctic sea ice reached a record low in 2012, according to a report released this week by the National Oceanic and Atmospheric Administration that pointed to continued signs of climate change．
The International Union for Conservation of Nature currently classifies polar bears as vulnerable on its Red List of Threatened Species．
小题1:How did Stirling know the reason for the death of the polar bear?

| B．By doing further experiments |
| C．By observing other polar bears |
| D．By his lying position in death |

| C．Doubtful． | D．Concerned |
| A．A novel． | B．A guidebook |
