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.
【C17】
选项 A、prevalent
B、principal
C、innovative
D、initial
答案D
解析 本题考查形容词辨析。本形容词的被修饰成分是doses，特别要注意本填空还受此前的代词those的限定，通过指代关系判断those指代的就是之前的More than three million doses，而More than three million doses指的则是再之前的The new vaccine，因此本填空的形容词与new属于同义复现；同时本填空之后的句子也提示了这种疫苗对pregnant women，people over 50 or those with breathing difficulties，heart disease等等这些人似乎不太好。综合这些线索确定四个选项中最合适的是D项initial(初始的，初期的)，即这些“新”疫苗是初始的，初期的，因此有些不完善的地方，D项initial把疫苗定义得最为准确。其他选项例如A项prevalent(流行的)和B项principal(主要的)属于原文没有线索支持的选项，故与题意无关。而C项innovative(创新的)具有干扰性，因为The new vaccine也可以理解为创新的疫苗，但同时考虑到本填空所在句子后面的信息已经明确指出这些疫苗对某些人群不好，说明这些疫苗并不完善，而C项innovative是正面的修饰，含有褒义色彩，表达不了不完善的概念，没有D项initial(初始的，初期的)定义得准确。
