【正确答案】
B
【答案解析】[听力原文] Those who use solar energy help us save our precious fuel. As you know, our supplies of oil and gas are very limited. There is just not enough on hand to meet all our future energy needs. And when Mother Nature says that's all, that's all. The only way we can delay hearing those words is by starting to save energy now and by using other sources, such as the sun. We won't have to worry about the sun's running out of energy for another several billion years or so. Besides being an endless source of energy, the use of the sun has other advantages as well. For example, the sun does not offer pollution as other energy sources. Furthermore, owners of solar homes will have extra protection against rising fuel costs. They will also have some protection against fuel shortage. When utility costs go up, owners of solar homes won't have to face the burdens brought about by increased costs. With all these good points, why don't we see more of solar power? There are many reasons for this. The biggest reason is money. Until now, it was just not practical for a home owner to put in a solar unit. There were cheaper sources of energy around. Solar costs are starting to equal the costs of oil and electricity. And experts say that gas will triple in cost in the next few years. In fact, gas is in such short supply right now that, in some places, it is not sold to new customers. Some customers are even having their supplies cut back. What is the only way to delay hearing Mother Nature's words about energy shortage? 短文提到，我们可以推迟听到那些话的唯一的方法就是，现在开始节省能源，并使用其他能源，如太阳能。B符合文意。 符合“语义突出之处常出题”的命题原则，听到the only way时要格外留意。此外，从常识的角度也可知，“节省能源并使用其他能源”是最合适的答案。C是对protection against rising fuel costs的胡乱改写，两者说的不是同一件事。
