Question

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

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(有效地).

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 the 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 kilometre down. At six kilometres， 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.

1.The writer tells about the "special houses" because they __________

A. show the excellent skills of the builders

B. serve as an example of energy conservation

C. are heated by different sources of energy

D. are warmer than other types of houses

2.The underlined words geothermal energy in the third paragraph mean________

A. renewable source         B. underground source

C. heat inside the earth    D. temperature of the earth

3.At a place where the surface temperature is 15℃， how deep do you have to dig so as to get a temperature of 75℃?

A. One km.     B. Two km.

C. Three km.    D. Four km.

Answer

1.B

2.C

3.B

【解析】

试题分析：短文大意：人们有很多种方法来解决能源问题：一种是提高能源产量，像煤，石油，天然气。但问题在于它们都是不可再生资源，另一种方法是节约能源，也就是说更加高效地利用。

1.B推理判断题。根据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.说明她们提出这个话题是用这个例子说明自己的观点。故B正确。

2.C词义猜测题。根据.In certain parts of the world the temperature of the earth increases thirty degrees centigrate with each kilometer down.说明这里的提及的geothermal energy就是指地热资源，故C正确。

3.1公里，温度上升30度。那么挖了2公里上升60度，原来还有15度，一共是75度，故B正确。
