W: What does the term "alternative energy source" mean?
M: When we think of energy or fuel for our homes and cars, we think of petroleum—a fossil fuel processed from oil removed from the ground, of which there is a limited supply. But alternative fuels can be many things. Wind, sun and water can all be used to create fuel.
W: Is the threat of running out of petroleum real?
M: It has taken thousands of years to create the natural stores of petroleum we have now. We are using what is available at a much faster rate than it has been produced over time. The real controversy surrounding the amounts of petroleum we have is how much we need to keep in reserve for future use. Most experts agree that by around 2025, the amount of petroleum we use will reach a peak. Then production and availability will begin to seriously decline. This is not to say there will be no petroleum at this point. But it’ll become very difficult and therefore expensive to extract.
W: Is that the most important reason to develop alternative fuel and energy sources?
M: There’re two very clear reasons to do so. One is that whether we have 60 or 600 years of fossil fuels left, we have to find other fuel sources eventually. So the sooner we start, the better off we will be. The other big argument is that when you burn fossil fuels, you release substances trapped in the ground for a long time, which leads to some long-term negative effects, like global warming and greenhouse effect.
5.What do we usually refer to when we talk about energy according to the man?
6.What do most experts agree on according to the man?
7.What does the man think we should do now?
8. How do fossil fuels affect the environment?
选项
A、Oil will soon be replaced by alternative energy sources.
B、Oil reserves in the world will be exhausted in a decade.
C、Oil consumption has given rise to many global problems.
D、Oil production will begin to decline worldwide by 2025.
答案
D
解析
在对话中,男士说目前的石油自然储备经历了数千年的时间才形成,人们使用现有石油资源的速度远远超过它在历史中的形成速度。大多数专家认为到2025年左右,人类所使用的石油量将达到顶峰,在那之后石油的产量和可用量将开始大大减少。故D项正确。A、B两项对话中未提及,C项对话中虽有提到,但不是大多数专家们同意的内容,故三项都可排除。
