上一題
Many of us have come to expect the traditional and reliable sources of energy will be available forever. But, what is the source of all this energy that we have used so carelessly? In most of the world, energy is created by burning fossil fuel— coal, natural gas, and oil. However, there is a problem. These resources are finite. And, at our current rate of use, by the year 2080, the world＇s supply of oil will almost be gone. Afterwards, the day will probably come when we will not have enough gasoline for our cars or electricity for our appliances. The three most commonly proposed solutions to this worldwide problem are increasing the efficiency of appliances and vehicles, improving conservation efforts, and finding alternative energy sources. Manufacturers have been working on the first solution for three decades. However, the overall consumption of appliances and vehicles continues to rise. The second solution is to improve our conservation like installing high-efficiency light bulbs in our homes, offices, and schools, and remember to turn off the lights in locations that we do not intend to use. Unfortunately, such strategies are only temporary solutions. Currently, the leading alternatives to fossil fuels are fusion and solar energy. The former is a nuclear reaction that results in a massive release of energy and is practically pollution-free. The latter can be utilized to heat water and buildings and to generate electricity and also purify fuels for automobiles.

(A)After 2080, all appliances and vehicles will not use traditional energy.
(B)Nuclear energy will probably become one of the alternative fuels in our future.
(C)Scientists＇ efforts to solve energy problems did not prove successful until 1999.
