　　HANOT－A 15-month-old girl and a man are the latest suspected cases of bird flu(流感) infection(感染) in Vietnam, a senior health official said on Wednesday as attention turned to pigs as possible carriers for the illness. Both patients are suspected of contracting avian influenza(禽流感) strain A, also known as H5NI, Dau Ngoc Hao, deputy director of the Agriculture Ministry's Veterinary Department in Hanoi, said. They were among 15 people who fell ill with influenza in Hanoi and surrounding provinces. Twelve, most of them children, have died. The World Health Organization said on Tuesday tests conducted by a Hong Kong laboratory had confirmed that bird flu killed three of the 15.

　　Hao suspected pigs were playing a role in the transmission of bird flu to humans. “It is possible that the bird flu virus spreads from chickens to pigs before jumping to humans,” he said, but did not laborate(详细描述). Local officials said ducks and pigs were also dying in southern provinces. By Wednesday, the virus has killed nearly 1.4 million chickens in the southern provinces of Long An and Tien Giang. “The situation in southern Vietnam is still very complicated,” Hao said. Peter Cordingley, a spokesman for the WHO'S Western Pacific headquarters in Manila, said:“We're worried that the virus will latch on to a normal human influenza virus, which is extremely contagious(传染性的) and then we'll have a big problem.” Cordingley stressed there was “no evidence of human-to-human transmission” among the Vietnam flu victims. “While there are people falling sick inside families, it's more likely that the transmission-if it comes from anywhere-comes from the chickens,” he said. Hanoi declared last week that it had been struck by a fast-spreading bird flu that has hit other countries nearby, which have a vast poultry(家禽) industry.

　　South Korea, which has already killed nearly 2 million chickens and ducks, reported last Tuesday the first new case of avian flu in more than a week, dashing hopes that the outbread was subsiding(平息). Hundreds of people living in affected areas have been given blood tests, although a health official said no one had shown symptoms of the disease. Japan reported its first bird flu outbread in years on Monday.

Answer 1

答案：A;B;B;A
解析：

1．A　　此文为新闻报道，主要报道了越南和其他一些亚洲国家禽流感的疫情状况。文中说：“they were among 15 people who fell ill with influenza in Hanoi and surrounding provinces. Twelve, most of them children, have died.”在15个患禽流感的人当中已有2人死亡，可见这种病死亡率极高，对人的生命危害极大，故选A。 　　2．B　　短文提到的Vietnam，South Korea，Japan国家都是亚洲国家，故可推断亚洲国家受禽流感之害最深。 　　3．B　　文中提到：pigs as possible carriers for the illness. “…pigs were playing a role in the transmission of bird flu to humans.”…no evidence of human-to-human transmission“可见科学家们认为人患禽流感极有可能是从猪身上传过来的，而非人与人之间的直接接触而传播。故B的说法是错误的。 　　4．A　　前题说到人患禽流感主要途径是猪，故可断定人吃了这种含有禽流感病毒的猪肉很可能患病。故A项最佳。
