Today I want to discuss fossil fuels such as coat, oil, and natural gas. The term "fossil fuel" refers to the trapped remains of plants and animals in sedimentary rock. You see, living plants trap energy from the sun by the process of photosynthesis, and they store the erergy in their chemical compounds. Most of that energy is released when the plant dies and decays. However, sometimes organic matter is buried before it decays completely. In this way some of the solar energy becomes trapped in rocks— hence the name fossil fuel. Although the amount of organic matter trapped in any one growing season is snail, the accumulated remains from millions of years are considerable. Because the accumulation rate is so slow—millions of times slower than the rate at which we now dig uo this organic matter and burn it for energy—we must consider fossil fuels as nonrenewable resources. Tomorrow we’ll be discussing alternatives to fossil fuels that can be renewed.
1. What is the main topic of this talk?
2. What does the speaker say about the accumulation of fossil fuels?
3. Why does the speaker refer to fossil fuels as nonrenewable?
选项
A、The process involved in the creation of fossil fuels.
B、The uses for different types of fossil fuels.
C、The methods for finding fossil fuels.
D、The measures taken to protect fossil fuels.
答案
A
解析
六级长篇听力题中常常会有一篇是有关科学的,并且里面难免出现一些生僻的词语。考生在解答与之相关的试题时,应该先浏览一下几个问题,在听时牢记里面的关键词,这样就能做到有的放矢了。在解答第1至第3题时,考生需要把握住“accumulation”(累积),“fossil fuel”(矿物燃料)和“nonrenewable”(不可更新的)这三个词。这篇文章主要是在谈论矿物燃料的形成过程,符合这一主题的只有A。
