Several years ago, the mayor of Chicago, Illinois decided to have vegetation planted on Chicago City Hall after he visited Germany, a leader in green roof design.

Green roofs are designed to save energy and collect rainwater. Roofs covered with plants help keep buildings cool. Earlier in 2008, researchers in Texas reported that green roofs can reduce a building's air conditioning costs by about one-fifth compared to blacktop roofs. Besides, vegetation on roofs helps stop water running off into streets and makes the life of a roof longer.
Researchers say green roofs usually do not get much above $27°\mathrm{C}$, so temperatures might not be a problem for growing. However, green roof 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.
“Not all green roofs perform well,” Mark Simmons, one of the researchers said. “Designs are different in keeping buildings cool and collecting rainwater. They have to be done right.” In order to improve green roof's conditions, researchers did many experiments. They compared products from different companies to help them understand how to make their designs work better. Researchers also found some native plants such as sedums which need little water. Therefore, they can help the green roofs take in more water and help keep buildings cool.
Today, the tops of some buildings in America look like farms as well as parks. Rainwater is used to grow lettuce, tomatoes, cucumbers, peppers and many other kinds of plants.

【分析】这是一篇关于绿色屋顶的英语阅读理解题，包含主旨大意题、细节理解题、词义指代题三类题型。解题思路：1. 主旨题需通读全文把握核心话题，排除片面选项；2. 细节题需定位原文对应段落，匹配题干关键词的相关表述；3. 指代题需定位代词所在句子，向前查找最近的名词短语确定指代对象。
【解析】1. 主旨大意题：通读全文，文章围绕“绿色屋顶（green roofs）”展开，介绍其作用、研究情况等。A选项仅提及芝加哥市长，过于片面；B选项“节能”只是绿色屋顶的作用之一，非核心；C选项“屋顶植物”仅为部分内容；D选项“关于绿色屋顶的一些内容”概括全面，故选D。2. 细节理解题：根据原文第二段“Besides, vegetation on roofs helps stop water running off into streets”及第四段“they can help the green roofs take in more water”，可知屋顶植物能帮助吸收更多水，A正确；B选项“使屋顶更高”原文未提及；C选项原文是“keep buildings cool（使建筑凉爽）”而非“cold（寒冷）”；D选项原文提到绿色屋顶减少空调成本，而非增加，故选A。3. 细节理解题：定位第四段，第一句“Not all green roofs perform well”后提到“Designs are different in keeping buildings cool and collecting rainwater”，说明不同绿色屋顶表现不同，C正确；A选项“省钱”是第二段内容，不属于第四段；B选项“设计困难”原文未提及；D选项“温度”是第三段内容，故选C。4. 词义指代题：定位第四段最后一句，向前查找最近的名词短语是“some native plants such as sedums”，因此“they”指代本土植物，B正确，故选B。
