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.

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.

选项

答案 E

解析 [语法判断]空格所在部分是目的状语，to是动词不定式的标志，因此空格处应填入动词原形。[语义判断]前一句提到，人们对在飞机上被普通呼吸道病毒传染的风险知之甚少。由此可知，研究团队此举是为了研究传染风险，因此应填入含有“研究，评估”意义的动词，故本题答案为E)evaluate。
