8.How to deal with 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(處理)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 dump site(垃圾填埋場).Residents or trash haulers(垃圾拖運者)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 modern society.The first problem is space.Dumps,which are now called landfills,are most needed in heavily populated areas.Such areas seldom have empty land suitable for this purpose.Land is either too expensive or too close to residential(住宅區(qū)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 led to 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,and many towns require their people to take part.Even the most efficient recycling programs,however,can hope to deal with only about 50per cent of a city's reusable waste.

分析 文章主要討論垃圾處理的問題,現(xiàn)代社會人們所使用的垃圾處理方法還和以前一樣,很難找到垃圾掩埋的地方.
解答 27-30 BACD
27 B 主旨大意題.根據(jù)文章第一段How to deal with waste has been a problem since humans started producing it.,可知自從人類開始產(chǎn)生垃圾,如何處理垃圾就成為了一個問題.所以文章最好的題目應該是"垃圾處理問題".
28 A 細節(jié)理解題.根據(jù)文章第二段倒數(shù)第二句"Periodically some of the trash was burned and the rest was buried"以及第三段第二句"Those located on rivers often just dumped the unwanted remains into the water"可知18世紀人們會通過燃燒垃圾、埋葬垃圾、投進河里的方式來處理垃圾.
29 C 推理判斷題.根據(jù)文章第四段Several facts make these choices unacceptable to modern society.可推斷處理垃圾的方法在現(xiàn)代社會保持不變.
30 D 推理判斷題.根據(jù)文章最后一段Even the most efficient recycling programs,however,can hope to deal with only about 50per cent of a city's reusable waste.
可知本文是對關于垃圾處理問題的探討,可推斷出作者寫這篇文章的目的是引起人們對垃圾管理的注意.
點評 學生需要認真閱讀原文,把握文章大意,對文章脈絡有整體的了解,能仔細查找文中細節(jié),并能根據(jù)文章內(nèi)容進行合理的推測判斷.
