Passage Four 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 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 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 cities 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 if garbage piling up on the earth． What two problems can man solve by burning garbage?
A、The shortage of energy and air pollutio
B、The shortage of energy and the land to hold garbag
C、Air pollution and the shortage of fossil fue
D、Air pollution and the shortage of land to hold garbag
【正确答案】：B
【题目解析】：题目询问的是通过焚烧垃圾可以解决的两个问题。 从文章中我们可以找到以下信息： * 第一段提到了两个问题：“我们如何处理垃圾？”和“我们是否有足够的能源来满足未来的能源需求？”。 * 文章随后讨论了使用垃圾作为能源来源的建议，并指出这样做可以同时解决这两个问题：能源短缺和垃圾存放用地的问题。 * 文章明确指出：“They suggest using garbage as an energy source, and at the same time it can save the land to hold garbage.” 这意味着使用垃圾作为能源可以同时解决能源短缺和垃圾存放用地的问题。 接下来我们来看选项： A. 能源短缺和空气污染 —— 文章没有提到焚烧垃圾可以解决空气污染问题。 B. 能源短缺和存放垃圾的土地 —— 这与文章中的描述相符。 C. 空气污染和化石燃料的短缺 —— 文章没有提到空气污染或化石燃料的短缺可以通过焚烧垃圾来解决。 D. 空气污染和存放垃圾的土地的短缺 —— 文章没有提到空气污染。 因此，正确答案是B，即焚烧垃圾可以解决能源短缺和存放垃圾的土地的问题。
