Question

【題目】 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 (屋頂) 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 (棲息地).

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

Answer 1

【答案】

【1】B

【2】D

【3】A

【解析】

本文以奧古斯登植物園為例，介紹了什么是綠色屋頂及其好處。它不止漂亮也有助于調(diào)節(jié)城市溫度。此外，綠色屋頂吸收雨水，保護城市排水系統(tǒng)。綠色屋頂充滿生機，使這座城市成為自然的一部分。

【1】細節(jié)理解題。根據(jù)第一段內(nèi)容可知，作者此處以奧古斯登植物園為例，解釋綠色屋頂是什么樣子的。故選B。

【2】詞句猜測題。raise升高；check檢查；record記錄；control控制，調(diào)節(jié)。根據(jù)“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，夏天普通屋頂?shù)母邷貢�讓頂層公寓熱得不舒服，但是綠色屋頂有助于保持建筑物的涼爽，所以此處moderate表示“控制，調(diào)節(jié)”的含義。故選D。

【3】推理判斷題。根據(jù)下文“Small animals and birds can make their homes on it.”可知，動物和小鳥可以在上面安家，所以綠色屋頂是充滿生機的。故選A。
