分析 本文是科普說明文,講新型的建筑東門大廈在哈拉雷,津巴布韋的首都,據(jù)說是世界上唯一一個(gè)使用與白蟻堆相同原理的制冷和制熱的建筑.它不需要裝空調(diào),幾乎沒有加熱系統(tǒng),而是利用天井和風(fēng)扇把外面新鮮空氣吸到辦公室里面,這樣空氣即新鮮又經(jīng)濟(jì).這一切之所以可能是因?yàn)楣滋囟ǖ臍夂蚝铜h(huán)境,在紐約不能做到這一點(diǎn).
解答 29-32 BADB
29.B.細(xì)節(jié)題:從第二段的句子:The Eastgate's owners saved 3.5millionona36 million building because an air-conditioning equipment didn't have to be imported.可知Eastgate比傳統(tǒng)的建筑便宜,因?yàn)樗恍枰b空調(diào),所以選B.
30.A.指代題.從第三段的句子:Fans suck fresh air in from the atrium,blow it upstairs through hollow spaces under the floors and from there into each office through baseboard vents(通風(fēng)口).可知風(fēng)扇把新鮮空氣天井吸入,把它(新鮮空氣)從地板下的中空的空間往上吹;最后從通風(fēng)口送進(jìn)辦公室,所以這里的it指"新鮮空氣",答案選A.
31.D.細(xì)節(jié)理解題.根據(jù)倒數(shù)第二段提到這種建造的一個(gè)條件是"…rapid temperature swings-days as warm as 31℃commonly drop to 14℃at night.(快速的氣溫變化--白天的氣溫31度而夜晚氣溫14度)";但是"You couldn't do this in New York,with its fantastically hot summers and fantastically cold winters,在紐約你無法這么做,因?yàn)榧~約夏天很熱冬天很冷,即紐約的天氣是季節(jié)變化而不是每天變化"得知答案選D
32.B.細(xì)節(jié)理解題.根據(jù)最后一段提到It is found that the temperature of the building has generally stayed between 23℃and 25℃,with the exception of ( 除了) the annual hot period just before the summer rains in October and three days in November,得知建筑物內(nèi)的溫度保持在23到25度,除10月與11月之外.所以這個(gè)系統(tǒng)一年的大部分時(shí)間都能用,因此答案選B.
點(diǎn)評 做閱讀理解時(shí)要快速的瀏覽全文,把握文章主旨大意,帶著問題回到原文,尋找細(xì)節(jié)或概括相應(yīng)的答案,最后要理清作者寫作思路.
