Question

【题目】 Fresh green grass, hundreds of colorful wild flowers, water running into little pools, birds making their homes in boxes, the 9,500-square-meter Augustenborg Botanical Garden may look just like any other well-organized park, but there’s a difference. It lies on the roofs (屋顶) of industrial and office buildings in the city of Malmo in Sweden.

Green roofs are not a new invention. And now they are getting popular again. The common roofs of a modern city have endless black surfaces with no life or water. Perhaps that’s why a garden on a roof becomes such a perfect choice for more and more people.

Green roofs are not just pretty. They also help to moderate the city temperature. The high temperatures on common roofs in the summer can make top floor flats uncomfortably hot. What is more, they play a part in making the cities hotter than the countryside around them, causing the “urban heat-island effect”. On a green roof, however, with its plants and water, temperatures change only a little, as they do in a park. Rooftops covered with plants help keep buildings cool. Green roofs take in rain water and protect the city drainage (排水) system. They can reduce water runoff into streets and storm water systems. This can greatly cut the costs of heating and cooling in the building below.

Also, _______. Small animals and birds can make their homes on it. Thanks to this, the city may become part of nature, rather than something completely separate from it. Though they won’t directly replace ground environments, they’re perfect for attracting birds and other wildlife to create a eco-friendly habitat (栖息地).

A green roof helps to improve the overall air quality, too. According to a study, green roofs help reduce (减少) up to:

37% of sulfur dioxide

21% of nitrous acid

0.2kg of dust particles / square meter each year

While the cost of building such a roof can still be higher, it can be cheaper in the long term as a result of energy savings. And wouldn’t it be wonderful to be able to walk out into a garden high above the city’s noise and traffic, whether you’re at school or in an office or just at home in a ten-floor block?

【1】With the example of Augustenborg Botanical Garden, the writer wants to explain ________.

A.how wildlife is protectedB.what a green roof is like

C.how to organize a good parkD.what to do with a spare roof

【2】The word “moderate” in Paragraph 3 probably means “________”.

A.raiseB.checkC.recordD.control

【3】Which of the following is the best sentence to fill in the blank in Paragraph 4?

A.a green roof is aliveB.a green roof protects animals

C.a green roof is perfectD.a green roof helps the environment

Answer 1

【答案】

【1】B

【2】D

【3】A

【解析】

本文以奥古斯登植物园为例，介绍了什么是绿色屋顶及其好处。它不止漂亮也有助于调节城市温度。此外，绿色屋顶吸收雨水，保护城市排水系统。绿色屋顶充满生机，使这座城市成为自然的一部分。

【1】细节理解题。根据第一段内容可知，作者此处以奥古斯登植物园为例，解释绿色屋顶是什么样子的。故选B。

【2】词句猜测题。raise升高；check检查；record记录；control控制，调节。根据“The high temperatures on common roofs in the summer can make top floor flats uncomfortably hot…Rooftops covered with plants help keep buildings cool.”可知，夏天普通屋顶的高温会让顶层公寓热得不舒服，但是绿色屋顶有助于保持建筑物的凉爽，所以此处moderate表示“控制，调节”的含义。故选D。

【3】推理判断题。根据下文“Small animals and birds can make their homes on it.”可知，动物和小鸟可以在上面安家，所以绿色屋顶是充满生机的。故选A。
