　　Ⅳ.阅读理解

　　A

　　Several years ago, the mayor of Chicago, Illinois, visited Germany, a leader in green roof design. Mayor Richard Daley later decided to have vegetation planted on Chicago City Hall. Today, the tops of many other buildings also look like parks. In Canada, the Coast Plaza Hotel in Vancouver has a forest on its roof. New York City has an unusual demonstration farm for hydroponics. The farm is on a boat called the Science Barge. Rainwater and purified river water are used to grow lettuce, tomatoes, cucumbers and peppers. The farm shows the possibilities for designing rooftop systems.

　　Green roofs are designed to save energy and capture rainwater. Rooftops covered with plants help keep buildings cool. They can extend the life of a roof. And they can reduce water running off into streets and storming water systems.

　　Experts say green roofs usually do not get much above twenty­seven degrees Celsius. So temperatures might not be a problem for growing. But rooftop gardeners have to be careful not to put too much weight on the roof. This is true whether plants are grown in soil or water.

　　Earlier in 2008, researchers in Texas reported that green roofs can reduce a building's air conditioning costs by about one­fifth compared to black­top roofs. But they also reported that not all green roofs perform equally well. They found that designs differ in their ability to keep buildings cool and to capture rainwater. The researchers put experimental roofs on top of metal insulated boxes, to recreate green roof conditions. The study compared products from six companies to help businesses understand how to improve their designs.Each rooftop had sixteen different kinds of plants native to Texas. The researchers say the presence of native plants likely helped all the green roofs capture water better compared to sedums. Sedums are plants that need little water and often are used on green roofs.The native plants could take in more water and release more of it to the atmosphere.

　　【语篇解读】 本文主要介绍了一种新的环保模式——绿色屋顶。

　　1．The author gave Paragraph 1 to________.

　　A．tell us what is green roof design

　　B．tell us Germany is the country that leads or guides the green roof design

　　C．introduce some famous hotels in the world

　　D．lead to the topic of the passage

　　答案　D　[推理判断。根据全文内容可知，第一段通过举例引出“绿色屋顶”的话题，为进一步阐述该话题作准备。]

　　2．The underlined word“storming”in Paragraph 2 can be replaced by________.　

　　A．attacking

　　B．controlling

　　C．attracting

　　D．managing

　　答案　A　[词义猜测题。根据句子结构分析，and连接两个并列成分，前面的running off into stress可知这里的storming也用作动词，意为“侵袭”。]

　　3．The advantages of green roofs are mentioned in the passage EXCEPT________.

　　A．changing the local weather

　　B．prolonging the roof's life

　　C．keeping the house cool

　　D．reducing the house's air conditioning costs

　　答案　A　[细节理解题。根据第二段中的Rooftops covered with plants help keep buildings cool. They can extend the life of a roof可知 B、C两项正确；根据最后一段首句可知D项正确。A项文中未提及。]

　　4．According to the passage，which conclusion is WRONG?

　　A．Sometimes green roofs may break down the house.

　　B．Not all the green roofs can reduce the building's air conditioning costs equally.

　　C．Different designs of green roofs have different effects on buildings.

　　D．Sedums are a kind of plants of native to Texas.

　　答案　D　[细节理解题。根据第三段中的rooftop gardeners have to be careful not to put too much weight on the roof可推出A项正确；根据最后一段中的But they also reported that not all green roofs perform equally well可知 B项正确；根据最后一段中的They found that designs differ in their ability to keep buildings cool and to capture rainwater可知C项正确；根据最后一段倒数第二、三句可知sedums不是Texas当地的植被。]

　　B

　　More than three billion people are at risk from indoor air pollution because of the heating or cooking fuels they use. Most live in Africa, India and China. They use biomass fuels like wood, crop waste, animal waste or coal. These solid fuels may be the least costly fuels available. But they are also a major cause of health problems and death.

　　The Aprovecho Research Center has been designing cooking stoves for the developing world. People having less money use wood or biomass for cooking;

　　the richer people use oil and gas. It's been estimated that wood is running out more quickly than oil and gas.

　　The group has made stoves using mud, bricks, sheet metal, clay, ceramics and old oil drums. Most of the stoves look like large, deep cooking pots. They have an opening at the bottom for the fire and a place on top to put a pot.

　　In the late nineteen seventies, Aprovecho produced a popular stove called the Lorena. The Lorena was very good at reducing smoke and warming homes. But new tests years later found that it was not very efficient. The Lorena used twice as much wood as an open fire, and took much longer to heat food. Since then, they have experimented with countless other designs.

　　Their goal is to make a very inexpensive stove－let's say five dollars－that makes very, very little smoke, so it's safe for health and global warming and deforestation(采伐森林).

　　Aprovecho has now partnered with a stove manufacturer in China. The company is making Aprovecho's first mass produced stoves. They are said to use forty to fifty percent less wood than an open fire, and produce fifty to seventy­five percent less smoke. A company called StoveTec is selling them through its Web site for less than ten dollars. Dean still says that more than one hundred thousand have been sold so far.

　　【语篇解读】 本文介绍了Aprovecho研究中心卓有成效的设计——一种价格优廉、效率高、低碳、清洁的炉子。

　　5．The underlined word“biomass”in Paragraph 2 refers to________.

　　A．oil and gas

　　B．wood

　　C．coal

　　D．crop waste or animal waste

　　答案　D　[词义猜测题。根据the richer people use oil and gas可以排除A选项。第一段中介绍发展中国家的人们使用wood，crop waste, animal waste or coal，而biomass所在的句子为People having less money use wood or biomass for cooking，故可排除B选项，煤炭也是需要花钱的，因此最便宜的燃料除了木头就是crop waste, animal waste。]

　　6．The following sentence is taken from the passage, it should be placed at the end of________.

　　The World Health Organization estimates that over 1,500,000 people a year die from breathing smoke from solid fuels.

　　A．Paragraph l

　　B．Paragraph 2

　　C．Paragraph 3

　　D．Paragraph 4

　　答案　A　[推理判断题。由第一段最后一句But they are also a major cause of health problems and death可知这些燃料会产生很多健康问题甚至造成死亡，而题干中的句子是以具体举例来说明这些燃料的危害的，所以选A项。]

　　7．Which of the following about the Lorena mentioned in Paragraph 4 is WRONG?

　　A．It was a popular stove which began to be produced in 1970.

　　B．It was able to be used with less smoke.

　　C．It was good at heating houses.

　　D．It needed more fuels than an open fire.

　　答案　A　[细节理解题。根据第四段中的In the late 1970s, Aprovecho produced a popular stove called the Lorena可知，A项表述错误。也可以运用排除法得出答案。]

　　8．Stoves designed by the Aprovecho Research Center should be________.

　　①luxurious　②costly　③efficient　④low­carbon　⑤cleaner

　　A．①②④

　　B．③④⑤

　　C．②③⑤

　　D．①③④

　　答案　B　[推理判断题。根据文章第五段内容可知，该研究中心设计的炉子应该具有价格优廉、效率高、低碳、清洁的特点。]
