问题    Disposing (处理) of waste has been a problem since humans started producing it. As more and more people choose to live close together in cities, the waste-disposal problem becomes increasingly difficult.
   During the eighteenth century, it was usual for several neighboring towns to get together to select a faraway spot as a dumpsite. Residents or trash haulers (垃圾托运者) would transport household rubbish, rotted wood, and old possessions to the site. Periodically (定期的) some of the trash was burned and the rest was buried. The unpleasant sights and smells caused no problem because nobody lived close by.
   Factories, mills, and other industrial sites also had waste to be disposed of. Those located on rivers often just dumped the unwanted remains into the water. Others built huge burners with chimneys to deal with the problem.
   Several facts make these choices unacceptable to modem society. The first problem is space. Dumps, which are now called landfills, are most needed in heavily populated areas. Such areas rarely have empty land suitable for this purpose. Property is either too expensive or too close to residential (住宅区的)neighborhoods Long-distance trash hauling has been a common practice, but once farm areas are refusing to accept rubbish from elsewhere, cheap land within trucking distance of major city areas is almost nonexistent.
   Awareness of pollution dangers has resulted in more strict rules of waste disposal. Pollution of rivers, ground water, land and air is a price people can no longer pay to get rid of waste. The amount of waste, however, continues to grow.
   Recycling efforts have become commonplace in recent years, and many towns require their people to take part. Even the most efficient recycling programs, however, can hope to deal with only about 50 percent of a city’s reusable waste.
During the 18th century, people disposed their waste in many Ways EXCEPT for______.
选项 A、burying it
B、recycling it
C、burning it
D、throwing it into rivers
答案B
解析 细节题。recycle“循环利用”。根据最后一段第一句对于垃圾的循环利用是最近才开始的一项技术，18世纪的时候是没有的，故答案为B。其他选项文中都被提及。
