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 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(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, 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.
1.The most suitable title for this passage would be ______.
A. Waste Disposal Problem B. Waste Pollution Dangers
C. Ways of Getting Rid of Waste D. Places for Disposing Waste
2.During the 18th century, people disposed their waste in many ways EXCEPT for ______.
A. burying it B. burning it
C. recycling it D. throwing it into rivers
3.What can be inferred from the fourth paragraph?
A. Farm areas accept waste from the city in modern society.
B. There is cheap land to bury waste in modem society.
C. Ways to deal with waste in modem society stay the same.
D. It is difficult to find space to bury waste in modem society.
心算口算巧算一课一练系列答案What is waste and why does it matter?
Waste or rubbish is something that people throw away because they no longer need it or want it. Almost everything we do creates waste and as a society we are currently producing more waste than ever before. We do this at home and at work. The fact that we produce waste, and get rid of it, matters for the following reasons.
When something is thrown away we lose the natural resources, the energy and the time which have been used to make the product. The vast majority of resources that we use in manufacturing products and providing services cannot be replaced. The use of these resources cannot go on indefinitely— we would run out.
When something is thrown away, we are putting pressure on the environment's ability to cope— in terms of the additional environmental impacts associated with extracting the new resources, manufacturing and distributing the goods, and in terms of the environmental impacts associated with getting rid of our rubbish.
When something is thrown away, we are not able to see it as a resource. It is well understood that what is waste to one person may not be viewed as waste by another. A good example of this is scrap metal（金属废料）which has been recycled for many years. Increasingly people are realizing that it makes economic sense as well as environmental sense to use "waste" rather than just throw it away.
The process of using up the earth's natural resources to make products which we then throw away, sometimes a very short time later, is not "sustainable" — in other words, it cannot continue indefinitely.
The way we consume materials will affect whether we have a sustainable society that leaves resources available for future generations to use. As consumers and producers, we are central to the concept of sustainability. We need to think about how we can get more out of less, how we can use less and throw away less and how we can do better things with our so-called "waste" than throw it away. We need to see "waste" as a "resource".
