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-metre 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 modem 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. This can greatly cut the costs of heating and cooling in the building below.

Also, a green roof takes in rain water, and protects the city drainage(排水) system. ____ And 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.

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.

本文以奥古斯登堡植物园为例介绍了什么是绿色屋顶以及绿色屋顶的好处。绿色屋顶不只是漂亮。它们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】考查细节理解。根据第一段的描述“新鲜的青草。数百朵五颜六色的野花水流入小水池。鸟在盒子里安家。这座面积为9500平方米的奥古斯登堡植物园看起来可能和其他组织良好的公园一样，但也有不同之处。它位于瑞典马尔默市工业和办公楼的屋顶上。”可知“以奥古斯登堡植物园为例，作者想解释一下绿色屋顶是什么样的。”故选B。

【3】考查细节理解。根据下文And small animals and birds can make their homes on it.（小动物和小鸟可以在上面安家。）可知此句是：绿色屋顶充满生机。故选A。
