Question

【題目】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(節(jié)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(壓；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

【答案】

【1】B

【2】C

【3】B

【解析】

試題分析：短文大意：人們有很多種方法來解決能源問題：一種是提高能源產(chǎn)量，像煤，石油，天然氣。但問題在于它們都是不可再生資源，另一種方法是節(jié)約能源，也就是說更加高效地利用。

【1】B推理判斷題。根據(jù)Another way is energy conservation(節(jié)能)，which means using energy more efficiently.In some very cold countries people build special houses to save energy.說明她們提出這個話題是用這個例子說明自己的觀點。故B正確。

【2】C詞義猜測題。根據(jù).In certain parts of the world the temperature of the earth increases thirty degrees centigrate with each kilometer down.說明這里的提及的geothermal energy就是指地熱資源，故C正確。

【3】B計算題。根據(jù)In certain parts of the world the temperature of the earth increases thirty degrees centigrate with each kilometer說明每向下1公里，溫度上升30度。那么挖了2公里上升60度，原來還有15度，一共是75度，故B正確。
