But in May 2003, veterinary officials in Alberta confirmed that a sick cow sent to a slaughterhouse in January of that year had been inspec

3、ted, found to be substandard, and removed so that it would not end up as food for humans or other animals. The carcass was, however, sent to a processing plant for rendering into oils. Its head was kept for testing. Samples were sent to the world testing laboratories in the U. K. , which confirmed t

4、he case of mad cow. “What is important is that the system worked,“ said Shirley McClellan, Albertas agriculture minister at the time. “We have a very thorough and respected inspection system.“ She was insistent to remind the public that the disease is not contagious within a herd. But McClellans ass

5、urances didnt stop the U. S. , Japan, South Korea, Australia and other countries from imposing temporary import bans of Canadian beef. Quick Facts Canada has close to 13.5 million cows and calves. About 5.7 million (or 42 percent) are in Alberta. Canadas total beef exports amount to $ 2.2 billion an

6、nually, and have risen sharply in recent years. Since 1991, beef exports have risen from 100,000 tons to about 500,000 tons. Growth in exports has been greatest to Japan, South Korea and Mexico. Albertas share of total beef exports is 39 percent (worth about $ 860 million a year). In an investigatio

7、n into the source of the infection, 1,400 cows were slaughtered and tested for the disease. No other cows were found to have BSE until late December 2004. Western premiers demanded $ 360 million compensation from the federal government for losses to the beef industry because of the mad cow scare. Ot

8、tawa would later offer $190 million. Over the summer of 2003, cattle ranchers held barbeques across Canada to help pro mote Canadian beef. In August, the U. S. reopened its borders to some Canadian beef, but the border was still closed to live cattle. By this time, a cow that would have normally sol

9、d for $1,300 was selling for $15. Canadian beef producers asked Ottawa to approve a mass slaughter of 620, 000 cattle to reduce the size of the herd and prevent further damage to the industry. In October, it was reported that the border would reopen to live cattle in December 2003. But on Dec. 23, 2

10、003, the U. S. announced that it had discovered its first apparent case of BSE in a cow in Washington State. Several countries banned beef from the U. S. soon after the announcement, but Canada restricted imports only on some products made from cattle and other ruminants. It still allowed the import

11、 of cattle destined for immediate slaughter, boneless beef from cattle under 30 months of age and dairy products. DNA evidence later revealed that the cow was born in Canada, and the U.S. kept its border shut to live Canadian cattle. On Dec. 29, 2004, The USDA announced that it recognized Canada as

12、a “minimal-risk region“ for BSE and imports of young Canadian cattle would resume March 7, 2005. The new classification means the U. S. will not again close its borders to Canadian beef unless there are two or more cases of BSE per one million cattle older than 24 months of age in each of four conse

13、cutive years. Simply put, Canada can have up to 11 cases of BSE and still be considered a safe country for cattle exports. The move came less than a month after U. S. President George W. Bush made his first official visit to Canada and said the process for reopening the border was underway. However,

14、 five days before the ban was to be lifted, a U. Sjudge granted a temporary injunction to stop the reopening of the border. The ban came at the request of a group of American ranchers called R-CAI.F, who filed a lawsuit saying reopening the border would cause irreparable damage to the U. S. beef mar

15、ket. In June 2005, the U. S. Department of Agriculture confirmed the countrys second known case of BSE, in a Texas-born cow. On July 14, 2005, a three-judge panel of the U. S. Ninth Circuit Court of Appeals overturned a temporary injunction that banned importation of Canadian cattle. U.S. Agricultur

16、e Secretary Mike Johanns announced that day that the U. S. border was “immediately“ open to live Canadian cattle. The British connection Previously, Canada had only one case of a cow infected with BSE. The animal, reported on a farm near Red Deer, Alberta. , in December of 1993, was imported from Br

17、itain. Agriculture Canada opted to destroy the animal and its five herd mates. Mexico, one of the largest importers of Canadian beef at the time, temporarily banned imports of Canadian cattle after the incident. The United States, another major consumer of Canadian beef, sent observers to Canada to

18、see how the incident was handled. As a result, and because of the rumors of possible human health implications circulating in Britain, the Ministry of Agriculture decided to destroy any animal imported from Britain between 1982 and 1990, the year a ban was placed on British beef imports to Canada. T

19、his slaughter also included the offspring of any of those animals. All told, 363 animals were destroyed and their owners compensated. Some said the destruction was unnecessary, especially the farms whose cattle were killed, but the ministry said it was better to err on the side of caution after seei

20、ng what was happening in Britain. As of January 2005, 148 Britons had died of CJD and five others were infected but still living. During the summer of 1995, the disease surfaced again. The Canadian Red Cross Society revealed two of its donors had died of Creutzfeldt-Jakob disease, CJD. Two years lat

21、er, concern over blood was raised again after a man was found to be a carrier of a gene linked to a hereditary form of CJD. In August 2002, doctors confirmed a man in Saskatchewan died from new variant CJD - the human counterpart to mad cow disease. He had spent some time in the United Kingdom and i

22、t appeared he acquired the disease while he was there, doctors said. The man had an endoscopic examination before he died and that equipment was then used on other patients. However, because of disinfection and cleaning procedures, the risk of cross contamination is minute. Public health officials p

23、honed patients who had received examinations with the endoscope to inform them. Its still not known if the disease can be transmitted through blood products. （分数：71.00）(1).The passage gives an overview of how Mad Cow Disease has affected the world in recent years. （分数：7.10）A.YB.NC.NG(2).Shirley McCl

He had heard about the revolution taking place in America. He w

40、anted to go and help. He was only eighteen years old. He was tall, handsome, and a familiar (38) 3 in the high society of Paris. His family tried to stop him. They asked the King of France to throw him into jail in order to stop him, but the young had already (39) 4 his own ship and (40) 5 some youn

44、tioned by the way we are brought up. Our values are determined by our parents, and in a larger sense, by the culture in which we live. The Chinese, for example, are not accustomed to the drinking of milk, and may actually become sick if they are compelled to drink a glassful of the beverage. America

45、ns, on the other hand, thrive on milk, although they have many taboos of their own. Some years ago I gave a dinner party during which I served a delicious hors doeuvre filled with a meat that tasted somewhat like chicken. My guests wondered what the meat was, but I refused to tell them until they ha

46、d eaten their fill. I then explained that they had just dined on the flesh of freshly killed rattlesnake. The reaction was nausea-and in some cases violent vomiting. If I had served rattlesnake to a Chinese, he would doubtless had requested a second helping, for in China the dish is considered a del

47、icacy. Another interesting case is the young man I met recently in New York City. An American by birth, he had been removed from his native state of Oregon at the age of six months when his parents went to Japan as missionaries. Orphaned before his first birthday, he was reared by a Japanese family in a remote village. The young man was unmistakably American in appearance, with blond hair and blue eyes. But he had a Japanese style of walking, Japanese facial expressions, and he thought like a Japanese. Though he had learned to speak English fluently, he
