　　If the sun has enough power to warm and light the whole earth, it must have enough power to do other things, too．Can we use the sun's abundant energy to supply electricity, or at least to perform the functions which electricity or other types of power usually perform?The answer is yes．

　　For example, people have for many years been using the reflected heat of the sun to cook．Solar cookers have been built with several curved(弯曲的)mirrors reflecting the sun and focusing its heat on the cooking component．This equipment can be used just like a gas or electric stove; it is more expensive to make but it does not need any fuel, and so costs nothing to use．Another possibility of using solar energy is in house heating．

　　The form of energy we use most is electricity, and every day more is needed．But electricity has to be made, too, and to make it, ____________ are required－oil, gas and nowadays even uranium(铀)．

　　The question which worries everyone today is ： how long will these fuels last?Nobody knows it for sure, but most experts think it will soon be difficult to obtain sufficient electricity from these sources．It is possible that the sun can make a contribution here, too．

　　Solar energy has already been used to produce terrific heat．In southern France a solar furnace has been built, where temperatures reach more than 3,000℃．This furnace is only used for experiments at present, but could be used to produce steam for a power station．
