阅读理解 These days a green building means more than just the color of the paint. Green buildings can also refer to environmentally friendly houses, factories, and offices. Buildings account for 65 percent of total U.S. electricity use. But green buildings can reduce energy and water use. Also, the buildings are often located near public transportation such as buses and subways, so that people can drive their cars less. That could be good for the environment, because cars use lots of natural resources such as gasoline, and give off pollution. Green buildings are often built on previously developed land, so that the buildings don''t destroy forests or other wild habitats (栖息地). Marty Dettling is project manager for a building that puts these ideas into action. The Solaire has been called the country''s first green residential high-rise building. According to Dettling, "We''ve reduced our energy consumption by one-third and our water by 50 percent." Not everyone is leaping to move into a green building, however. Some people think that features such as solar panels cost more money than more traditional energy sources. Despite this, Dettling hopes that green buildings will become common in the future. "It''s going to be big," she said.

单选题 What do green buildings refer to nowadays?

【正确答案】 A

【答案解析】本题与做所有阅读理解题的思路一致，即首先要找到文章中该道题所依据的句子，然后与其他选项进行比较，确定与依据句意思相同的选项为正确答案。本题中，文中的第二句话就是依据句。据此可以判断出B、C两项不正确，因其选择的信息文章中没有出现；D项不正确，因其缺少“green”一词的概念。因此本题的正确答案为A。

单选题 The word "Also" (Line 2, Para. 2) is used to______.

【正确答案】 B

【答案解析】要想解答本题，首先要弄清“also”的用法。“also”的词性为连词，用来引导一个并列的概念，与前面的句子相对应。本文中“also”连接的两个句子的意思为：绿色建筑能够节能省水。此外，绿色建筑紧挨公共汽车或地铁之类的公共交通线，住户可以少用自己的汽车。选项A、C、D不正确，因上述的两个句子都是有关节能绿色建筑的不同方面，都与环境保护有关系，而这三项与“also”所引导的句子没有呼应关系。因此正确答案为B。

单选题 Why are some people NOT so enthusiastic about green buildings?

【正确答案】 D

【答案解析】文章最后一段的第二个句子是本题的依据句，意思是：有些人认为，像太阳能电池板这样的设施，其费用大大超过了传统的能源设施。据此，A、B选项不正确，因其选择的内容没有在文章中出现，属于无关信息。C项不正确，它强调的是太阳能电池板的费用高，但这只是诸多因素的一个方面。D项选择的意思强调绿色建筑的运行成本高。这一观点依据是：绿色环保的前期费用大大高于传统的节能方式，正好是本句话的意思。因此正确答案为D。

单选题 What did Marry Dettling mean when she said "It's going to be big"?

【正确答案】 C

【答案解析】本题的支持信息和线索在文章的最后一个句子中。通过分析可以看出，green buildings will become common in the future与it's going to be big为同义句子。据此，A、B、D三项不正确，因为这三项的信息在文章中没有出现。正确答案为C，因为“绿色建筑具有很大潜力”最接近依据句的意思。
