问题     Until recently, the medical community believed that most hearing loss was caused by hear cells in the ear degrading as we age. But evidence is emerging that sound levels at sporting events, concerts, nightclubs and on personal devices can cause lasting damage to the connections between hear cells in the ear and the nerves that【C1】______sounds to the brain. Over 1. 1 billion teenagers and young adults worldwide could be at risk of hearing loss as a result of【C2】______to unsafe levels of recreational noise, according to a recent World Health Organization report. To make matters worse, this kind of hearing loss doesn’t show up on【C3】______tests. Researchers are calling it a hidden epidemic. " We think this problem is【C4】______prevalent, but it’s difficult to measure because the tools we have available today are not sensitive enough," says Konstantina Stankovic, an auditory neuroscientist and surgeon at Massachusetts Eye and Ear, and Harvard Medical School, in Boston.
    Stankovic is now working with colleagues at the Swiss Federal Institute of Technology in Lausanne to develop imaging【C5】______that would allow us to see this kind of neural damage in living brains. This could help with early diagnosis. Others are developing drugs that could help【C6】______the connections between the ear and the brain.
    To properly【C7】______our ears, loud noises should be banned in many public places just as smoking is now, says Stankovic. Some countries have laws in place to protect【C8】______in bars and clubs by monitoring noise levels. Last year, Minneapolis City Council made it【C9】______for bars and clubs to offer free ear buds to patrons. Stankovic thinks more will need to be done to change【C10】______accepted norms around recreational noise. " I think it will require a public health effort similar to the efforts for limiting smoking, because of the peer pressure associated with loud music and noisy environments," she says.
A)compulsory I)socially
B)condense J)standard
C)exposure K)techniques
D)incredibly L)transmit
E)independently M)treat
F)protection N)uneasy
G)restore O)workers
H)safeguard
【C4】
选项
答案D
解析 该空格位于系动词之后，其后形容词prevalent充当句子的表语，由此推断应该填入副词，充当状语，修饰形容词。本句引用了听觉神经科学家及医生Stankovic的话，说明由于娱乐环境噪音所导致的听力损伤问题已经普遍到惊人的程度，故答案为D)incredibly“难以置信地”。备选项中，E)independently“独立地，自立地”和I)socially“社会地，社交地”与上下文语义不符，故均可排除。
