[解析] Health authorities in many countries are taking urgent steps to control the spreading swine flu crisis which is now on the brink of a full-blown pandemic. Since it was identified as a serious public health issue, the new swine flu virus has been blamed for making thousands of people ill. Health authorities in the Asia-Pacific region have swiftly responded to the situation. Hong Kong, the Philippines and Australia activated swine flu hotlines Thursday as part of stepped-up efforts to prevent an outbreak. Authorities have also urged the public to maintain good hygiene to prevent the spread of the virus. In the Asia-Pacific, only New Zealand has confirmed cases of swine flu. Philippine health officials went on television Thursday to alert the public of the threat of a pandemic as described by the World Health Organization. Health Secretary Francisco Duque said personal hygiene is the first line of defense against swine flu. (9) "Wash your hands regularly with soap and water, especially after you cough or sneeze. Alcohol-based hand cleaners are also effective. Please avoid close contact with sick people." (10) In Australia, Prime Minister Kevin Rudd says the government has stepped up surveillance at borders. Japan said Thursday it will tighten quarantine checks. [解析] 辨别题。新闻中直接提到：Health Secretary Francisco Duque said personal hygiene is the first line of defense against swine flu. 可见要预防禽流感，个人卫生是关键，因此答案为B。新闻中还提到：Health authorities in many countries are taking urgent steps to control the spreading swine flu crisis which is now on the brink of a full-blown pandemic. 即禽流感已蔓延到大规模流行的边缘，这表明尚未大规模流行，可以排除A，同时新闻也提到只有新西兰报告确定感染病例，澳大利亚提升边境监控等级，由此可以排除C和D，所以答案为B。 document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
