问题    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.
Which of the following is NOT true according to the passage?
选项 A、About 2 million metric tons of garbage is burned in some power plants in Paris, France each year.
B、In modern society, more and more garbage is produced each year.
C、Using garbage is a good way to solve the problem of energy shortage.
D、It will be too expensive to use garbage as an energy source.
答案D
解析 细节题。根据文章第四段第五句可知，在法国巴黎，一些发电厂每年焚烧近200万吨城市垃圾，选项A(法国巴黎的一些电厂每年焚烧大约200万吨的城市垃圾)正确。根据第三段第三句可知，选项B(在现代社会，每年人们制造的垃圾越来越多)正确。根据第四段可知，选项C(焚烧垃圾是解决能源问题的一个好方法)正确。选项D(把垃圾作为能源太贵)文中未提及，故本题选D。
