Question

Ways to Deal with the Problem of Energy
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,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 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 centigrate with each kilometer down.At six kilometers,therefore,it rises to nearly 200degrees.To get the heat,water is pumped down into the rocks and back up to the surface.Heat from the earth is already used in certain countries

1. 1.
   The writer tells about “the special houses”because they______
   1. A.
      show the excellent skills of the builders
   2. B.
      serve as an example of the energy conservation
   3. C.
      are heated by different sources of energy
   4. D.
      are warmer than other types of energy
2. 2.
   The underlaned words”geothermal energy”in the third paragraph mean____
   1. A.
      renewable source
   2. B.
      underground source
   3. C.
      heat inside the earth
   4. D.
      temperature of the earth
3. 3.
   At a place where the surface temperature is 15degrees centigrade,how deep do you have to dig so as to get a temperature of 75 degrees centigrade?
   1. A.
      One km
   2. B.
      Two km
   3. C.
      Three km
   4. D.
      Four km

Answer 1

BCB
试题分析：本文介绍了人们为了保护环境而节约能源，使用多种资源的故事。
1.B 推理题。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 推理题。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.B 计算题。根据In certain parts of the world the temperature of the earth increases thirty degrees centigrate with each kilometer说明每向下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。
