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【C1】________by the World Health Organization in 41 years.
    The heightened alert【C2】________an emergency meeting with flu experts in Geneva that convened after a sharp rise in cases in Australia, and rising【C3】________in Britain, Japan, Chile and elsewhere.
    But the epidemic is "【C4】________" in severity, according to Margaret Chan, the organization’s director general,【C5】________the overwhelming majority of patients experiencing only mild symptoms and a full recovery, often in the【C6】________of any medical treatment.
    The outbreak came to global【C7】________in late April 2009, when Mexican authorities noticed an unusually large number of hospitalizations and deaths【C8】________healthy adults. As much of Mexico City shut down at the height of a panic, cases began to【C9】________in New York City, the southwestern United States and around the world.
    In the United States, new cases seemed to fade【C10】________warmer weather arrived. But in late September 2009, officials reported there was【C11】________flu activity in almost every state and that virtually all the【C12】________ tested are the new swine flu, also known as (A) H1N1, not seasonal flu. In the U.S., it has【C13】________more than one million people, and caused more than 600 deaths and more than 6,000 hospitalizations.
    Federal health officials【C14】________Tamiflu for children from the national stockpile and began【C15】________ orders from the states for the new swine flu vaccine. The new vaccine, which is different from the annual flu vaccine, is【C16】________ahead of expectations. More than three million doses were to be made available in early October 2009, though most of those【C17】________doses were of the FluMist nasal spray type, which is not 【C18】________for pregnant women, people over 50 or those with breathing difficulties, heart disease or several other【C19】________. But it was still possible to vaccinate people in other high-risk group: health care workers, people【C20】________infants and healthy young people.
【C2】

选项 A、proceeded
B、activated
C、followed
D、prompted

答案C

解析 本填空考查动词。动词的主语是The heightened alert,宾语是an emergency meeting with flu experts in Geneva,并且之后出现了that引导的定语从句来修饰先行词flu experts(流感专家),这说明这些流感专家是在澳大利亚的病例数激增以及英国、日本、智利和其他地方的感染人数上升之后在日内瓦开的会。把握了这些原文信息就很容易定位本填空的动词两边的主语与宾语之间的关系,即肯定是先要由流感专家在日内瓦开会(an emergency meeting with flu experts in Geneva),会议之后才会加强警戒(The heightened alert),这是唯一合理的关系。四个选项中能正确表达这个关系的只有C项followed(随后)。其他选项例如B项activated(激活)和D项prompted (促使)表达的意思是“提升和加强警戒级别(The heightened alert)”造成了“流感专家在日内瓦开会(an emergency meeting with flu experts in Geneva)”,这是明显错误的。A项proceeded(继续)是不及物动词,不能直接接宾语,在语法上和意义上均属错误。
