【答案及詳解】

　　　　　　　答案：
　　1.A)Its excessive use of air-conditiong對應原文Today most Americans need to take air-conditioning for granted to homes, offices, factories, theatres, shops, studios, schools, hotels, and restaurants.
　　take sth for granted認為某事理所當然　
　　2.B)the reduction of social communications of neighborhood life對應原文forced families into retreating into families with closed doors and shut windows, reducing the interactions of neighborhood life
　　neighborhood life社區生活
　　選項A并未對應題干中的According to the author　而是對應原文中的some medical experts suggest that
　　3.標準答案是C)brings more benefits than damage to its users，但我認為應該選D)does harm as well as good to its users，對應原文最后一句If so, air-conditioning is only like many other greatly useful technical developments(positive words)that liberate man from nature by increasing his productivity and power in some way - while indirectly weakening him in others(negative words)，于是does harm as well as good to its users.
　　4.D)Consumers是最精確的。原文直接批判空調的一句話是forced families into retreating into families with closed doors and shut windows, reducing the interactions of neighborhood life，顯然according to the author，consumers為從空調中受益最少的。而ABC三個選項，BC可以作為by increasing his productivity的受益者，A的工作性質則完全與空調無關，ABC甚至也都可以成為D的一種。
　　5.C)Critical對應原文It has, at will, forced，聽起來很像批判。
　　at will隨意　任意
