问题     The outbreak of swine flu that was first detected in Mexico was declared a global epidemic on June 11 , 2009. It is the first worldwide epidemic【B1】______by the World Health Organization in 41 years.
    The heightened alert【B2】______an emergency meeting with flu experts in Geneva that assembled after a sharp rise in cases in Australia, and rising【B3】______in Britain, Japan, Chile and elsewhere.
    But the epidemic is"【B4】______"in severity, according to Margaret Chan, the organization’s director general ,【B5】______the overwhelming majority of patients experiencing only mild symptoms and a full recovery, often in the【B6】______of any medical treatment.
    The outbreak came to global【B7】______in late April 2009, when Mexican authorities noted an unusually large number of hospitalizations and deaths【B8】______healthy adults. As much of Mexico City shut down at the height of a panic, cases began to【B9】______in New York City, the southwestern United States and around the world.
    In the United States, new cases seemed to fade【B10】______warmer weather arrived. But in late September 2009, officials reported there was【B11】______flu activity in almost every state and that virtually all the【B12】______tested are the new swine flu, also known as (A) H1N1 , not seasonal flu. In the U. S. , it has【B13】______more than one million people, and caused more than 600 deaths and more than 6, 000 hospitalizations.
    Federal health officials【B14】______Tamiflu for children from the national stockpile and began【B15】______orders from the slates for the new swine flu vaccine. The new vaccine, which is different from the annual flu vaccine, is【B16】______ahead of expectations. More than three million doses were to be made available in early October 2009, though most of those【B17】______doses were of the FluMist nasal spray type, which is not【B18】______for pregnant women, people over 50 or those with breathing difficulties, heart disease or several other【B19】______. But it was still possible to vaccinate people in other high-risk groups; health care workers, people【B20】______infants and healthy young people.
【B2】
选项 A、proceeded
B、activated
C、followed
D、prompted
答案C
解析 本题考查考生对句间逻辑关系和词汇用法的掌握。本句主语为“警觉性提高”，宾语为“各 国出现高发病例后在日内瓦召开的流感专家紧急会议”，这里需填入体现两者逻辑上先后关系的谓 语。选项[B]activated与[D]prompted词义分别为“启动、触动”、“引起、促使”，虽可以和“emergency meeting”搭配，但是不符合逻辑常识，应是流感专家紧急会议造成公众对此问题的警觉性提高。选项[A]proceeded可以表示“继续”，但一般要和“to”或“with”连用。因此选项[C]followed(在……后发生)为正确答案。
