问题 We are in an energy crisis and we will have to do something quickly. The world’s energy resources are limited, and fuels are rapidly running out. Nobody knows exactly how much fuel is left, but experts say that there is only enough coal for 450 years, enough natural gas for 50 years and that oil might run out in 30 years. The tragedy is that fuels are too valuable to waste on the production of electricity. If we don’t start conserving these things now, it will be too late. And nuclear power is the only real alternative.

选项

答案我们正处在能源危机之中,我们必须尽快采取一些措施。世界上的能源资源非常有限,并且很快就要用完。没有人准确地知道还剩多少燃料,但专家说煤只够用450年,天然气50年,石油可能只有30年。悲剧在于燃料太珍贵了不能浪费在发电上。如果我们现在不开始保护这些燃料的话,将来就来不及了。而核能是惟一真正的选择。
