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 dump site．Residents or trash haulers（垃圾拖运者）would transport household rubbish,rotted wood,and old possessions to the site．Periodically 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 rarely have empty land suitable for this purpose．Property is either too expensive or too close to residential 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,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．
The most suitable title for this passage would be ______．
A．Places for Disposing Waste B．Waste Pollution Dangers
C．Ways of Getting Rid of Waste D．Waste Disposal Problem
During the 18th century,people disposed their waste in many ways EXCEPT for ______．
A．burying it B．recycling it
C．burning it D．throwing it into rivers

A．Farm areas accept waste from the city in modern society．
B．There is cheap land to bury waste in modern society．
C．It is difficult to find space to bury waste in modern society．
D．Ways to deal with waste in modern society stay the same．

Disposing of the garbage we produce every day is a major problem in cities around the world. In the United States, over 160 million tons of garbage is produced every year. Ten percent is recycled, ten percent is burned, and the rest is put in landfills. But finding land for new landfills is becoming more difficult.
A city that has solved this problem in an unusual way is Machida in Tokyo. They have developed a totally new way of dealing with garbage. The key to the operation is that people should work together. Families must divide their garbage into six groups:
|
1. garbage that can be easily burned, such as kitchen and garden trash 2. garbage that doesn’t burn easily, such as plastic tools and plastic toys 3. products that are poisonous or that cause pollution, such as batteries 4. bottles and glass containers that can be recycled 5. metal containers that can be recycled 6. large items, such as furniture and bicycles |
The items in Groups 1 to 5 are collected on different days. Large items are only collected upon request. Then the garbage is taken to a centre that looks like a clean new office building or hospital. Inside the centre, special equipment is used to sort and deal with garbage. Almost everything can be reused: garden or kitchen trash becomes fertilizer; garbage that can burn is burned to produce electricity; metal containers and bottles are recycled; and old furniture, clothing, and other useful items are cleaned, repaired, and resold cheaply or given away. The work provides employment for the disabled and gives them a chance to learn new skills.
Nowadays, officials from cities around the world visit Machida to see whether they can use some of these ideas and techniques to solve their own garbage problems.
