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 to tear them all down and 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 carbon emissions (排放) from a(an) __ _ energy-efficient (節(jié)能) home to make up for the lost by destroying an old one.
So in the broadest sense, the greenest home is the one that has already been built.But at the same time, half of US carbon emissions come from heating, cooling and powering our , offices and other buildings."You can't deal with climate without dealing with existing buildings," says Richard Moe, the president of the National Trust.
With some exceptions, the oldest homes tend to be the energy-efficient.Houses built before 1939 use about 50% more energy per square foot than those built after 2000, mainly due to the tiny cracks and gaps that over time and let in more outside .
,there are a vast number of relatively simple changes that can green older homes, from ones like Lincoln's Cottage to your own postwar home.And efficiency upgrades (升級) can save more than just the earth; they can help property owners from rising power .

試題分析:
本文試圖說明,全部拆除老舊房屋代之以新的節(jié)能型房屋是不劃算的,因?yàn)樾滦头课菟鶞p少的排放需要幾十年才能補(bǔ)償拆除舊房屋所損失的資源。對于老舊房屋做一些簡單的改變,既能拯救地球,也可讓房主免受資源成本攀升之累。
1.下文提到:那些老舊房屋建造時(shí)投入了大量的能源和資源,新型綠色房屋減少的排放量平均需要65年才能補(bǔ)償拆除老舊房屋損失的資源。所以全部拆除老舊房屋是一種“浪費(fèi)”。故B項(xiàng)正確。
2.拆除老舊房屋,“代之以”相對綠色的房屋。replace A with B: 用B替代A. 故C項(xiàng)正確。
3.新型節(jié)能型房屋應(yīng)該能夠“減少”碳排放。故答案為A。
4.“新型”節(jié)能型房屋,與“老舊”房屋相對。故C項(xiàng)正確。
5.文章第二段提到:建造那些老舊房屋投入了大量的energy和resources。而綠色房屋所減少的排放量平均需要65年才能抵充拆除老舊房屋損失的“資源”,包括建筑材料(materials)等有形資源,也包括投入的勞動等無形資源。故答案為D。
6.“幾乎”一半的碳排放來自家居等處的取暖、制冷以及用電。mostly: in most cases. 多數(shù)情況下。用以修飾動詞。nearly: 接近、差不多。程度副詞,修飾形容詞或副詞。故A項(xiàng)正確。
7.第二段提到“新型節(jié)能型home”;常理也告訴我們,居家是人們待的時(shí)間最長的處所。學(xué)校、圖書館、商店等以”other buildings”概括。故C項(xiàng)最佳。
8.不處理現(xiàn)有建筑帶來的問題就不能處理氣候“變化”問題。故D項(xiàng)正確。improvement: 改善、改良。appearance: 外貌、樣貌;出現(xiàn)。stability: 穩(wěn)定性。不合題意!案纳茪夂颉笔切枰覀?nèi)ネ瓿傻娜蝿?wù),不是一個(gè)需要處理的“問題”。“氣候穩(wěn)定”更不是“問題”。
9.下文提到,39年之前建造的房屋比2000年后建造的房屋每平方英尺要多耗費(fèi)50%能源。這是由于老舊房屋縫隙擴(kuò)大,需要更多能源來保暖或制冷。所以,年代越是久遠(yuǎn)的房屋,能源使用效率越低。 最老舊的房子當(dāng)然是能源利用效率最低的。故D項(xiàng)正確。least efficient: 效率最低。
10.老舊房屋時(shí)間久遠(yuǎn),故而縫隙“擴(kuò)大”。expand: 擴(kuò)大、擴(kuò)張。A項(xiàng)正確。
11.縫隙擴(kuò)大,密封程度差,外面的“空氣”就會進(jìn)來。故答案為B.
12.拆除浪費(fèi);不拆也浪費(fèi)。“幸運(yùn)的是”,有許多相對簡單的改造方法可以使老舊房屋綠化。A. 相反。B. 不幸的是。C. 幸運(yùn)的是。D. 坦率講。故C項(xiàng)正確。
13.Lincoln’s cottage (林肯的小屋)提示此處選擇historic(有歷史意義的)。故答案為A。
14.對于老舊房屋能源利用效率的提升,可以使房主免受成本不斷攀升之累。protect sb. from sth. 使某人免受……之苦。charge: 收。ㄙM(fèi)用);punish: 懲罰;warn: 警告。均不合題意。B項(xiàng)正確。
15.對于老舊房屋能源利用效率的提升,可以使房主免受“成本”不斷攀升之累。cost指必須付出的代價(jià);price指價(jià)格。“價(jià)格”上升,并不必然意為著“成本”上升,這要根據(jù)“收入與支出比”來確定。故B項(xiàng)正確。

科目:高中英語 來源: 題型:閱讀理解
Tuesday was the eighth day of the 12 th month on the Chinese lunar calendar. I first became aware of the day as a traditional festival called laba, or the eighth day of the winter month – when I was working in a factory 30 years ago.
At lunch time,some elder co-workers opened their lunch boxes, and out came the sweet smell of well-cooked rice porridge mixed with beans,nuts and dates(棗)and they talked excitedly. Then, I wondered why there should be such an unnecessary excitement over the laba festival. Growing up during the “cultural revolution” (1966-1976), when almost all traditional things were considered out-of-date,I had scarcely become aware of most of the traditional festivals.
I really started to value and celebrate these traditional festivals when I began to write about Chinese culture. It is really encouraging that, despite the dramatic changes and modernization that our country has experienced over the past three decades, people have come to treasure many of our traditions more. Some people may have a complaint against the extreme commercialization(商業(yè)化)of these traditional festivals, but I believe the business promotions have at least worked to increase people’s awareness.
Most of the traditional Chinese festivals are celebrated with feasts. No wonder that on Tuesday a lot of people were buying rice,nuts,dry fruit, and beans from supermarkets and stores. A few thousand went to the Yonghegong Lama Temple to make prays for peace and happiness.
Now that we have celebrated laba festival,we are now looking forward to the Lunar New Year, when we are supposed to have a lot more feasts. In fact, it is reported that almost all popular restaurants have been booked out for the Lunar New Year Eve dinner in major cities across the country.
1.As a whole,the passage is mainly organized by_________.
A.space B.examples C.time D.comparison
2.What is the writer’s attitude toward Chinese Festivals?
A.He takes them seriously all the time.
B.He values them more than before.
C.He expects only the Lunar New Year.
D.He thinks Chinese Festival are too commercialized.
3.The common ways to celebrate traditional Chinese festivals in the passage are to________.
① stop working in the factory ② enjoy some special delicious food
③ have feasts with the family or friends ④ pray for peace in temples
⑤ buy rice,nuts,fruits and beans ⑥ write about Chinese culture
A.①③⑤ B.②⑤⑥ C.①④⑥ D.②③④
4.From the last paragraph it can be inferred that now_________.
A.people are eager to show their richer life
B.people have become tired of laba festival
C.people are living a better life than before
D.people are always active in celebrating festivals
