原创完型填空(1篇,15题,附解析)

When we think of green buildings, we tend to think of new ones—the kind of modern, solar-paneled masterpieces that make the covers of architecture magazines.

But the US has more than 100 million existing homes, and it would be incredibly 1 to tear them all down and 2 them with greener versions.

An enormous amount of energy and resources went into the construction of those houses. And it would take an average of 65 years for the 3 carbon emissions(排放)from a(an) __4 _ energy-efficient(节能)home to make up for the resources lost by destroying an old one.

So in the broadest sense, the greenest home is the one that has 5 been built. But at the same time, 6 half of US carbon emissions come from heating, cooling and powering our homes, offices and other 7 . “You can’t deal with climate 8 without dealing with existing buildings,” says Richard Moe, the president of the National Trust.

With some exceptions, the oldest homes tend to be the 9 energy-efficient. Houses built before 1939 use about 50% more energy per square foot than those built after 2000, 10 due to the tiny cracks and gaps that 11 over time and let in more outside air.

12 , there are a vast number of relatively simple changes that can green older homes, from

13 ones like Lincoln’s Cottage to your own postwar home. And efficiency upgrades(升级)can save more than just the earth; they can help 14 property owners from rising power 15 .

答案解析：

1.B 本句提到tear them all down“把它们全部推倒”，结合文章大意可知，推倒这些房子是很浪费的，故本题选B项。

2.C 根据前半句中的tear them all down“把它们全部推倒”可知，此处是说把旧房子换成更节能的房子，所以本题选C项。

3.A 本段讲的是关于节能房子，所以此处肯定是减少的排放，故选A项reduced。

4.C 根据本段中的energy-efficient home“节能房子”可知，此处说的房子肯定是新的，因

为新房子才是节能的，所以本题选C项。

5.D 根据本段可知，房子已经建好了，所以本题选D项already“已经”。

6.A 根据四个选项可以选出答案，A项nearly“将近”；B项hardly“几乎不”；C项rarely “很少地”；mostly“主要地”。四个选项中只有A项符合文意。

7.C 空格前的our homes, offices都是建筑物，所以此处选C项buildings。

8.D 根据全文可知，建节能房子是为了解决气候变化的问题，所以本题选D项。climate change表示“气候变化”。

9.D 根据前两段可知，旧房子不节能，所以本题选D项least。

10.B 根据本段可知，空格后提到的the tiny cracks“小裂缝”是旧房子需要消耗更多能源的主要原因，所以本题选B项。

11.A 根据本句中的let in more outside air“使外面的空气进来”可知，裂缝是变大了，所以本题选A项expand“张开”。

12.C 根据空格后的there are a vast number of relatively simple changes that can be green older homes可知，这是一件好事，所以此处选C项。

13.A 空格后给出的例子Lincoln’s Cottage 和your own postwar home都是比较古老的，历史上有重大意义的房子，所以本题选A项。

14.B 本题考查固定搭配。根据空格前后的单词，结合上下文语境可知，B项符合文意。protect…from…表示“保护……免受……”。

15.B 根据本句中的save more than just the earth和rising power可知，节能房子可以减少开支，所以本题选B项。
