17.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.
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 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.

分析 本文是一篇社會文化類閱讀,人們在建造房屋時,不僅考慮到地區(qū)的氣候,還有建筑材料及房屋的風(fēng)格.然而,隨著電越來越貴,人們?yōu)榱耸狗课葸_到保暖驅(qū)寒的效果,更加注重新的保存能量的方式.本文以此展開,講述了人們一些保存能量的方法.
解答 32.答案:B.細節(jié)理解題.根據(jù)第一段第二句"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 house from both cold and heat."說明人們?yōu)榱耸狗课葸_到保暖驅(qū)寒的效果,更加注重新的保存能量的方式.故選B.
33.答案:A.細節(jié)理解題.根據(jù)第二段"In some parts of the world,people share their houses with their livestock (家禽).During cold weather,they gather their cows,goats,or other animals and keep them on the first floor of their houses."可知,他們讓家禽住在樓下來獲取熱量.故選A.
34.答案:D.詞意猜測題.由劃線詞所在句的上一句"However,home builders use the fact that heat rises."可知,that 引導(dǎo)同位語從句指代熱量上升的原理,故"natural law"指代的也是熱量上升的原理.故選D.
35.答案:B.推理判斷題.根據(jù)第一段前兩句知人們在房屋建設(shè)時依然需要考慮建筑材料.從第三段可知利用巖石吸熱隨后放熱的方法只是針對生活在城市及城市郊區(qū)的人們,且只是其中的一種方法.故選B.
點評 本文是一篇社會文化類閱讀,題目涉及多道細節(jié)理解題,推理判斷題,詞意猜測題,做題時學(xué)生應(yīng)仔細閱讀原文,把握文章主要內(nèi)容,聯(lián)系文章上下文內(nèi)容并結(jié)合所給選項含義,從中選出正確答案,一定要做到有理有據(jù),切忌胡亂猜測.
