When building houses, people used to think about not only the climate of the areas but also the building materials and the fashions for their houses. However, since electricity became more and more expensive, people began to pay much more attention to the energy they could get for their houses and the new ways they could find to protect their houses from both cold and heat.
Now, houses of an old yet new type have been widely built. In some parts of the world, people share their houses with their livestock(家畜).During cold weather, they gather their cows, goats, or other animals and keep them on the first floor of their houses. The reasons are that the animals can be protected from the cold and that they can help to heat the houses as well. The body heat given off by the animals rises to the second floor of the houses, where people live. By sharing their houses with their livestock, people gain a source of heat.
People who live in or near cities do not usually keep livestock. However, home builders use the fact that heat rises. This natural law can be used in building houses in these areas. Instead of keeping livestock on the first floor, builders fill it with large rocks. As they are open to the sun’s rays during cold weather, these rocks take in heat. They also give off the heat, and, of course, the warm air rises into the living areas of the houses. So these houses are energy-saving.
House-building bees a great challenge to building designers and energy engineers. They try to meet this challenge by learning from old traditions and by using modern technology. And someday in the future, people will be able to live in more energy-saving houses.

(答案→)B 
解析: 因电能能越来越贵,为了使房屋达到住房保暖驱寒的效果,人们越来越注重研究新的保存能量方式
【小题1】B细节理解题。第一段第二句说明人们为了使房屋达到保暖驱寒的效果,更加注重新的保存能量的方式。
【小题2】A细节理解题。第二段第二、三句及尾句可知
【小题3】B词义理解题。由划线词所在句的上一句可知,that 引导同位语从句指代热量上升的原理。
【小题4】B推断判断题。由第一段前两句知人们在房屋建设时依然需要考虑建筑材料。从第三段可知利用岩石吸热随后放热的方法只是针对生活在城市及城市郊区的人们,且只是其中的一种方法
