问题    Finally, some good news about airplane travel. If you are on a plane with a sick passenger, you are unlikely to get sick. That is the【C1】______of a new study that looked at how respiratory (呼吸道) viruses【C2】______on airplanes. Researchers found that only people who were seated in the same row as a passenger with the flu, for example—or one row in front of or behind that individual—had a high risk of catching the illness. All other passengers had only a very【C3】______chance of getting sick, according to the findings. Media reports have not necessarily presented【C4】______information about the risk of getting infected on an airplane in the past. Therefore, these new findings should help airplane passengers to feel less【C5】______to catching respiratory infections while traveling by air.
   Prior to the new study, little was known about the risks of getting【C6】______infected by common respiratory viruses, such as the flu or common cold, on an airplane, the researchers said. So, to【C7】______the risks of infection, the study team flew on 10 different【C8】______in the U. S. during the flu season. The researchers found that passengers sitting within two seats on【C9】______side of a person infected with the flu, as well as those sitting one row in front of or behind this individual, had about an 80 percent chance of getting sick. But other passengers were【C10】______safe from infection. They had a less than 3 percent chance of catching the flu.
   A) accurate F) explorations K) slim
   B) conclusion G) flights L) spread
   C) directly H) largely M) summit
   D) either I) nearby N) vividly
   E) evaluate J) respond O) vulnerable
【C5】
选项
答案O
解析 [语法判断]空格前有系动词feel，且有比较级形式less，因此应填入形容词。[语义判断]所给形容词中，能与to搭配的只有vulnerable，将vulnerable带入句中，句意为：因此，这些新发现应该可以帮助飞机乘客在飞行时感到不那么容易感染呼吸道疾病。因此，本题答案为O)vulnerable。
