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(節(jié)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

   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

試題分析：本文介紹了人們?yōu)榱吮Ｗo(hù)環(huán)境而節(jié)約能源，使用多種資源的故事。
1.B 推理題。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(gè)話題是用這個(gè)例子說明自己的觀點(diǎn)。故B正確。
2.C 推理題。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?zé)豳Y源，故C正確。
3.B 計(jì)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。
考點(diǎn)：考查自然知識(shí)類短文
點(diǎn)評(píng)：文章基本上是考查細(xì)節(jié)題，對(duì)此類題型考生可以首先從問題中找到關(guān)鍵詞，然后以此為線索，運(yùn)用略讀及查閱的技巧在文中迅速尋找這一細(xì)節(jié)，找到后再把這一部分內(nèi)容仔細(xì)閱讀一遍，仔細(xì)比較所給選項(xiàng)與文中細(xì)節(jié)的細(xì)微區(qū)別，在準(zhǔn)確理解細(xì)節(jié)的前提下，最后確定最佳答案。
