Question

    Pollution's serious effects on the environment have become more obvious in recent years. Most scientists agree that efforts are necessary to protect our environment from further harm. As we know, the construction industry consumes a large quantity of energy and resources and creates a huge amount of pollution. So green buildings are in great need.

The environmental benefits of building green include the protection of ecosystems and biodiversity（生物多样性）, improved air and water quality, less waste flowing into streams and the protection of natural resources. Green buildings can also result in lower operating costs because they typically use less energy and fewer materials and improve indoor air quality, improving the health of people who live there.

The process of building green includes technical and artistic planning with nature protection in mind. Building designs often reflect the surrounding environment and natural resources and use renewable building materials such as bamboo and straw. In addition, recycled resources found locally are used for green buildings, reducing the cost and air pollution associated with transporting materials long distances.

Careful site selection is important to minimize（最小化）human effect on the surrounding environment. For example, placing a structure in an area that allows it to take advantage of cool breezes（微风）and sunlight can reduce energy use and expenses. More energy and expense are needed for larger buildings as well, so it is important to build small.

Green roofs are another feature of green houses that reduce energy use and cost. These roofs are partially or completely covered with plants, which helps to keep heating and cooling costs low, prevent water running off and deal with pollutants.

Other features of green buildings often include energy and water protection, recycling and waste reduction. In addition, renewable energy sources such as solar power, water power and wind power are used for heat and electricity, which greatly reduces costs and decreases the influence on the environment.

1.Which advantage is not included about the building green?

A.To upgrade the quality of air and water.

B.To reduce the waste flowing into streams.

C.To protect the ecosystems and biodiversity.

D.To enhance our human being's life quality.

2.What is a green building probably like according to paragraph 4?

A.Small B.Large.

C.Warm. D.Cool.

3.Why do we choose to use green roofs?

A.To fit the environment, B.To lower expenses

C.To collect nature water. D.To keep warm or cool.

4.What is the text mainly about?

A.Environmental benefits. B.Building green.

C.Promoting energy efficiency. D.Ecosystems and biodiversity.

【解析】

本文是一篇说明文。介绍了绿色建筑的各种特点能够更加有效的改善空气和水的质量，减少废物流入河流，使自然资源得到保护。

1.

细节理解题。根据第二段The environmental benefits of building green include the protection of ecosystems and biodiversity （生物多样性）,improved air and water quality, less waste flowing into streams and the protection of natural resources. 建造绿色建筑的环境效益包括保护生态系统和生物多样性，改善空气和水质，减少流入河流的废物以及保护自然资源。D项“提高人类的生活质量”未提及。故选D 项。

2.

推理判断题。根据第四段More energy and expense are needed for larger buildings as well, so it is important to build small.大型建筑物也需要更多的能源和费用，因此建造小型建筑物很重要。因此，绿色建筑最有可能是小型建筑。故选A项。

3.

细节理解题。根据第五段Green roofs are another feature of green houses that reduce energy use and cost.屋顶绿化是温室的另一个特点，可以减少能源消耗和成本。因此，选择使用绿色屋顶是为了降低开支。故选择B项。

4.

主旨大意题。文章主要讲述了绿色建筑的各种特点能够有效的改善空气和水的质量，减少废物流入河流，进而使自然资源得到保护，及结合第一段中的“So green buildings are in great need.” 因此，非常需要绿色建筑。B项“建造绿色建筑”符合文章主要内容。故选B项。
