Have you ever wondered why winter is flu season—why people never seem to catch the disease in July and August? A group of microbiologists at New York’s Mount Sinai School of Medicine says it has found the answer.
One of the microbiologists, Peter Palese, discovered by chance the【R6】______to the answer while reading an old scientific article about the 1918 flu pandemic(大流行病). A pandemic is a【R7】______outbreak of a disease. The 1918 flu pandemic, which began in the United States, killed about 25 million people around the【R8】______.
In the article, which appeared in the Journal of the American Medical Association in 1919, researchers in New York noted that their guinea pigs(天竺鼠)got sick and died when the pandemic【R9】______through the state. That was the first time Palese had heard that guinea pigs are likely to suffer from the disease. Other animals that might be used for influenza experiments either do not【R10】______the influenza virus or are too difficult to work with.
Palese bought some guinea pigs and【R11】______them to the virus under different environmental conditions. He and his colleagues discovered that the rodents(啮齿动物)were most likely to transmit the virus under winter conditions—low temperatures and low moisture. By【R12】______, the virus was not transmitted at all in summer conditions—high temperatures and high【R13】______.
The flu virus, which moves from person to person through the air, is most stable in【R14】______air, says Palese. Low humidity helps the virus remain airborne because the water droplets that the virus travels on are smaller then,【R15】______becoming too heavy to remain in the air.
A. rarely B. contrast C. transmit D. moisture E. comparison
F. frequently G. worldwide H. track I. cold J. globe
K. transfer L. path M. widespread N. exposed O. swept
【R14】
选项
答案
I
解析
此处应填形容词,来修饰其后的名词air。文章意思是:流感病毒在冷空气中最稳当。它正是通过空气从一个人传播到另一个人身上。故I正确。
