Passage Twenty-three

（K4 level）

1.There are different ways in which people try to deal with the problem of energy.

2.One way is the greater production of common energy sources, such as coal, oil and gas.

3.The trouble with these sources, however, is that they are not renewable.

4.Another way is energy conservation, which means using energy more efficiently.

5.In some very cold countries, people build special houses to save energy.

6.They put materials between the inside and the outside of the walls of the house to keep the cold out and the warmth in.

7.The house is heated by the lights, the body heat of the people and the other equipment in it.

8.Finally, renewable energy sources are used even though they are often expensive to develop.

9.One form of these is geothermal energy.

10.In some parts of the world the temperature of the earth increases thirty degrees centigrade with each kilometre down.

11.At six kilometres, therefore, it rises to nearly two hundred degrees.

12.To get the heat, water is pumped down into the rocks and back up to the surface.

13.Heat from the earth is already used in some countries.

1. 人们尝试用不同的方式来解决能源问题。

2. 一种方式是增加常见能源来源的生产，比如煤、石油和天然气。

3. 然而，这些能源来源的问题在于它们不可再生。

4. 另一种方式是节约能源，这意味着更高效地使用能源。

5. 在一些非常寒冷的国家，人们建造特殊的房屋来节约能源。

6. 他们在房屋内外墙之间放置材料，以阻挡寒冷进入并保持室内温暖。

7. 房屋由灯光、人们的体温以及其中的其他设备来供暖。

8. 最后，尽管开发成本较高，人们仍然使用可再生能源来源。

9. 其中一种形式是地热能。

10. 在世界上的某些地方，地表以下每下降一公里，温度会升高30摄氏度。

11. 因此，在六公里处，温度接近200摄氏度。

12. 为了获取热量，人们将水泵入岩石层中，然后再抽回地面。

13. 一些国家已经在利用地球内部的热量。
