There are different ways in which people try to deal with the problem of energy. One way is greater production of common energy sources(能源), such as coal, oil and gas. The trouble with these sources, however, is that they are not renewable.
Another way is energy conservation(节能), which means using energy more efficiently. In some very cold countries people build
special houses
to save energy. They place materials between the inside and the outside of the walls of the house to keep the cold out and the warmth in. The house is heated by the lights, the body heat of people and the other equipment in it.
Finally, renewable energy sources are used even though they are often expensive to develop. One form of these is
geothermal energy
. In certain parts of the world the temperature of the earth increases thirty degrees centigrade with each kilometer down. At six kilometers, therefore, it rises to nearly two hundred degrees. To get the heat, water is pumped(压, 抽)down into the rocks and back up to the surface. Heat from the earth is already used in certain countries.
At a place where the surface temperature is 15 ° C, how deep do you have to dig so as to get a temperature of 75° C?( )
选项
A、One km.
B、Twokm.
C、Threekm
D、Fourkm.
答案
B
解析
推断题。地表温度为15度,每下降一公里温度上升30度,要想到75度,至少要挖到2.公里处。因此B选项正确。
