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． The best title for the passage may be______
A、Garbage and the Earth
B、Fossil Fuel and Garbage
C、Land and Garbage
D、Garbage?Energy Source
【正确答案】：D
【题目解析】：首先，我们需要理解文章的主要内容。文章首先提出了两个问题：如何处理垃圾以及我们是否有足够的能源来满足未来的需求。随后，文章主要围绕将垃圾作为能源源的可能性进行了讨论，提到了垃圾在化学上与化石燃料相似，可以作为一种能源使用，并列举了一些城市将垃圾作为能源使用的例子。 现在，我们来看各个选项： A. Garbage and the Earth - 这个标题更侧重于垃圾和地球的关系，但文章主要讨论的是垃圾作为能源的可能性，所以这个标题不够准确。 B. Fossil Fuel and Garbage - 这个标题提到了化石燃料和垃圾，但文章并没有深入讨论两者之间的关系，而是专注于垃圾作为能源的可能性，所以这个标题也不合适。 C. Land and Garbage - 这个标题主要关注的是土地和垃圾的关系，但文章的主要焦点并不在此。 D. Garbage?Energy Source - 这个标题明确指出了文章的主题，即垃圾作为一种可能的能源源。这与文章的主要内容高度一致。 综上所述，最佳标题应为D：Garbage?Energy Source。
