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.
12 What is the only way to delay hearing Mother Nature’s words about energy shortage?
13 What will owners of solar homes not worry about?
14 What is the biggest reason for not using more solar power now?
15 How will the price of gas most be likely to change in the next few years according to experts?

选项 A、It will go up.
B、It will come down.
C、It will go up and down.
D、It will stay the same.

答案 A

解析 ①由选项可知,本题问It在未来的发展趋势。It在此处指代的是the price of gas。②短文提到,专家们说在接下来的这些年里gas的价格会增至三倍(triple)之高。即其价格将上涨,因此本题选A。
