Question

【题目】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 becomes a great challenge（挑战）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.

【1】What did people begin to consider as electricity was no longer cheap?

A. The climate of their areas. B. The energy for their houses.

C. The fashions for their houses. D. The building materials for their houses.

【2】People in some areas gain a source of heat by _________.

A. keeping their livestock downstairs

B. protecting their livestock from the cold

C. sharing their houses only with their cows

D. living on the second floor with their livestock

【3】The underlined words “natural law” in the third paragraph refer to the fact that ________.

A. heat raises the temperature in the houses

B. heat goes in the upward direction

C. heat goes up if temperature is raised

D. heat increases the temperature of rocks

【4】From the passage, we can conclude that __________.

A. people will no longer consider building materials in the future

B. energy-saving buildings will become more popular in the future

C. almost all people will move into the houses heated by large rocks

D. energy engineers will devote themselves only to modern technology

Answer 1

【答案】

【1】B

【2】A

【3】B

【4】B

【解析】试题分析：人们修建房屋的时候，不仅考虑当地的气候，还要考虑建筑材料和时尚。未来，节能型房屋会越来越受欢迎。

【1】B细节理解题。根据第一段最后一句people began to pay much more attention to the energy they could get for their houses人们开始关注房子的能量问题。故选B项。

【2】A细节理解题。根据第二段第一句people share their houses with their livestock (家畜)人们与家畜同住和下一句they can help to heat the houses家畜可以帮助抵御寒冷，可知一些地方的人们通过与家畜共同居住来获取热量。故选A项。

【3】D推理判断题。根据第三段内容，natural law应指代上句的 the fact that heat rises热量上升这一事实，故选D项。

【4】B推理判断题。根据最后一段内容：房屋设计师和能量工程师们不断借鉴传统技术和使用新技术，努力满足人们修建房屋的新需求。也许不久的将来，人们能够住进更节能的房子。可以推断出节能房屋将会越来越受欢迎。故选B项。
