　　Part IV Reading Comprehension (Reading in Depth) (25 minutes)

　　Section A

　　Directions: In this section, there is a passage with ten blanks. You are required to select oneword for each blank from a list of choices given in a word bank following the passage. Read thepassage through carefully before making your choices. Each choice in the bank is identified bya letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single linethrough the centre. You may not use any of the words in the bank more than once.

　　Questions 47 to 56 are based on the following passage.

　　When we think of green buildings, we tend to think of new ones – the kind of high-tech,solar-paneled masterpieces that make the covers of architecture magazines. But the U.S. hasmore than 100 million existing homes, and it would be __47__ wasteful to tear them all downand __48__ them with greener versions. An enormous amount of energy and resources wentinto the construction of those houses. And it would take an average of 65 years for the__49__ carbon emissions from a new energy-efficient home to make up for the resources lostby destroying an old one. So in the broadest __50__, the greenest home is the one that hasalready been built. But at the same time, nearly half of U. S. carbon emissions come fromheating, cooling and __51__ our homes, offices and other buildings. "You can't deal with climatechange without dealing with existing buildings," says Richard Moe, the president of the NationalTrust.

　　With some __52__, the oldest homes tend to be the least energy-efficient. Houses builtbefore 1939 use about 50% more energy per square foot than those built after 2000, mainlydue to the tiny cracks and gaps that __53__ over time and let in more outside air.

　　Fortunately, there are a __54__ number of relatively simple changes that can green olderhomes, from __55__ ones like Lincoln's Cottage to your own postwar home. And efficiencyupgrades (升级) can save more than just the earth; they can help __56__ property ownersfrom rising power costs.

　　section A

　　文章大意：本文关注的是绿色建筑与对待现存房屋的问题。根据文意，所谓绿色建筑即为节能减排的建筑。绿色建筑在节能减排方面意义重大，但是将所有现存房屋替换成绿色建筑是否可行呢?文章给出的答案是不可行的，因为推倒这些房屋进行重建也需要大量能量。那么，如何处理这些能耗大的旧房屋呢?文末给出的建议是对它们进行整修和升级。

　　47. G incredibly

　　首先这里需要的是一个副词。根据文意，将这些房屋推倒代之以绿色建筑是极度浪费的。因此选incredibly.

　　48. K replace

　　replace A with B, 意思是用B 替换A. 这里是用绿色建筑取代现存房屋。

　　49. J reduced

　　这一句话较难理解，翻译成中文即：绿色建筑带来的碳排放量的减少平均需要65年才能够补偿推倒房屋所用掉的能量。reduced, 这里用作形容词，指减少了的。

　　50. L sense

　　in the broadest sense, 在最广义上，这里是一个固定搭配。

　　51. H powering

　　这里的and 引导的是平行结构，因此横线上需要填入一个动词的ing形式。在根据句意可知这里选powering，指为某物提供动力，使某物得以运行。

　　52. D exceptions

　　联系下文可知本段意思是老房子基本上是最不节能的。但话不能说得这么绝对，因此用 with someexceptions, 指除一些特殊情况外。

　　53. E expand

　　tiny cracks and gaps 指的是小的缝隙和缺口。小的缝隙和缺口随着时间流逝，会扩大，从而使得外面空气流入，因而加大了能耗。这里选expand表示扩展，增大。

　　54. O vast

　　a number of 表示大量的，number前面可加一些形容词，如great等，表示数量极大的。这里填入vast，意为数量巨大的。

　　55. F historic

　　句中有from……to……, 从什么到什么，联系整句话，意思是从一些历史上的古老建筑到你自己的战后的房子。postwar 指二战后，是一个较近的时间，与之对应的则是historic.

　　56. I protect

　　首先，从句意判断，可知这一分句仍是陈述为老房屋进行升级的好处。此外，后半句中有介词from. 据此我们可以判断，此处应填入的词是protect.
