How can we get rid of garbage? Do we have enough energy sources to meet our future energy needs?
These are two important questions that many people are asking today. Some people think that man might be able to solve both problems at the same time. They suggest using garbage as an energy source, and at the same time it can save the land to hold garbage.
For a long time, people buried garbage or dumped(倾倒)it on empty land. Now, empty land is scarce. But more and more garbage is produced each year. However, garbage can be a good fuel to use. The things in garbage do not look like coal, petroleum, or natural gas: but they are chemically similar to these fossil(化石)fuels. As we use up our fossil fuel supplies, we might be able to use garbage as an energy source.
Burning garbage is not a new idea. Some cities in Europe and the United States have been burning garbage for years. The heat that is produced by burning garbage is used to boil water. The steam that is produced is used to make electricity or to heat nearby buildings. In Paris, France, some power plants burn almost 2 million metric tons of the city garbage each year. The amount of energy produced is about the same as would be produced by burning almost a half million barrels of oil.
Our fossil fuel supplies are limited. Burning garbage might be one kind of energy source that we can use to help meet our energy needs. This method could also reduce the amount of garbage piling up on the earth. [br] The best title for the passage may be "______".
选项
A、Garbage and the Earth
B、Fossil Fuel and Garbage
C、Land and Garbage
D、Garbage—Energy Source
答案
D
解析
主旨题。本文在一开始通过问题的方式引起我们对垃圾和能源问题的关注,然后提出有人建议用垃圾作为能源,接着举例说明这种做法在有的地方已经付诸实践,最后指出把垃圾作为能源的好处。所以本文核心思想是垃圾焚烧与能源之间的关系,所以选项D(垃圾——能源)符合题意。选项A(垃圾与地球)、选项B(化石燃料和垃圾)和选项C(土地和垃圾)虽然都涉及核心词垃圾,但是不符合文章的中心思想,故本题选D。
