The Association of Flight Attendants (AFA), 【22】______which 42, 000 flight attendants with 27 airlines are represented, evidently thinks so. The organization claims that the incidence of air-quality-related diseases has【23】______among its members and demands that prompt actions be【24】______to improve the conditions in the airplane cabin.
A study the AFA【25】______in 1997 uncovered about 1, 000 self-reported incidents of headaches, dizziness and memory loss【26】______flight attendants and passengers. Some flight attendants were too ill to【27】______their safety duties, while others have been permanently disabled.
Because of airlines’ efforts to【28】______their expenses, cabin-air filters are not cleaned【29】______. The complaints of flight attendants do not always give【30】______to correct maintenance. Airlines turned to recycled air, 【31】______that they would reduce some of their costs. They are not required to put filters in. Airlines are【32】______great pressure to get their flights out【33】______. So they do not pay as much attention to systems that are not as【34】______to flight schedule and safety.
Recent research findings emphasize the concern that filters can【35】______engine chemicals into the cabin air. This may not happen【36】______every flight, but it is a persistent problem.

选项
A、concerning
B、including
C、relating
D、attaching
答案
A
解析
including包括…在内,表示前面所提事物包括后面出现的事物,两者属于同一范畴,且是隶属关系,而“complaints”与“air quality and health”不属于同一范畴,故排除B;relating与attaching均须与介词“to”连用来表示“关于,与…相关联”,故排除C、D;concerning关于,涉及,后面可以直接跟名词,如:the official documents concerning the sale of this land,故选A。
