Many people who fly at least occasionally have come down with a cold or the flu shortly after disembarking. Is the air in airborne commercial jets【C1】______? The Association of Flight Attendants (AFA),【C2】______which 42, 000 flight attendants with 7 airlines are represented, evidently thinks so. The organization claims that the incidence of air-quality-related diseases has【C3】______among its members and demands that prompt actions be【C4】______to improve the conditions in the airplane cabin.
A study the AFA【C5】______in 1997 uncovered about 1, 000 self-reported incidents of headaches, dizziness and memory loss【C6】______flight attendants and passengers. Some flight attendants were too ill to【C7】______their safety duties, while others have been permanently disabled.
Because of airlines’ efforts to【C8】______their expenses, cabin-air filters are not cleaned【C9】______. The complaints of flight attendants do not always give【C10】______to correct maintenance. Airlines turned to recycled air,【C11】______that they would reduce some of their costs. They are not required to put filters in. Airlines are【C12】______great pressure to get their flights out【C13】______. So they do not pay as much attention to systems that are not as【C14】______to flight schedule and safety.
Recent research findings emphasize the concern that filters can【C15】______engine chemicals into the cabin air. This may not happen【C16】______every flight, but it is a persistent problem.
In a study published in October 1998 an investigation was made【C17】______complaints of crew members【C18】______air quality and health. More than half of the 200 subjects reported health problems they【C19】______to cabin air. It was concluded that these health problems were consistent with【C20】______harmful gases and substances.

选项
A、exposure to
B、exploration of
C、formation of
D、compensation for
答案
A
解析
exposure意为“显露,暴露”,可与介词“to”搭配,如:Exposure of the body to strong sunlight can be harmful.根据句意,这些健康问题是与长期暴露于有害气体及物质当中相关,A项符合文意;exploration意为“勘探,探索”;formation意为“组成,形成”;compensation意为“补偿,赔偿”,均不符合文意。
