                                   Cloning

                                     李仕才
 一、阅读理解

    Pollution’s great effects on the environment have become more obvious in 

recent years, leading to a movement to promote energy efficiency(效率),less 

reliance on fossil(化石) fuels, and a reduction in air and water pollution. Most 

scientists agree that such changes are necessary to protect our environment from 

further harm.

    The construction industry consumes a large quantity of energy and resources 

and creates a huge amount of pollution. In the United States, building and 

development account for 39% of the country’s total energy use, 12% of total 

water consumption,68% of total electricity consumption and 38% of carbon dioxide 

emissions(二氧化碳排放), according to the Environment Protection Agency.

    Green buildings use less energy, water, create less waste, and are healthier 

to live, work, and go to school in than standard buildings. Builders of green 

buildings use techniques that use resources more efficiently during the entire 

building cycle—construction, restoration, operation, maintenance(维护)and 

demolition(拆毁)—than those who construct more regular buildings.

    The environmental benefits of building green include the protection of 

ecosystems(生态系统)and biodiversity, 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 in such buildings.

    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 over long distances.

    Careful site selection is important to minimize(最小化)human impact 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 partly or completely covered with plants, which helps to 

keep heating and cooling costs, prevent water running off and deal with 

pollutants.

    Other features of green buildings often include energy and water conservation, 

recycling, and waste reduction. In addition, renewable energy sources such as 

solar power, hydropower(水能)and wind power are used for heat and electricity, 

which greatly reduces costs and decreases the impact on the environment.

1.What is the text mainly about?

  A. The necessity of promoting energy efficiency.

  B. The process of building green buildings.

  C. The benefits and features of green buildings.

  D. Green buildings effects on the environment.

2.According to the text, green buildings refer to the buildings that______.

  A. produce no waste

  B. only use clean energy

  C. are made of recycled materials

  D. use energy and resources more efficiently

3.Which of the following statements is TRUE about green buildings?

  A. They rely on fossil fuels and solar power for heat and electricity.

  B. Small buildings are less efficient in energy use than larger ones.

  C. The ecosystem has to be considered when building a green building.

  D. They are difficult to maintain and thus need more operating costs.

4.Why are green roofs used ?

  A. They fit the surrounding environment well
                   中国现代教育网     www.30edu.com  全国最大教师交流平台

  B. They are cheaper than other kinds of roofs

  C. They can keep natural water for use in everyday life

  D. They can help to control the temperature in the building well

    【文章大意】在本文中作者主要分析了                 green building 的诸多好处和对环境的巨大的保

护作用,呼吁人们多建设这样的绿色的建筑。

1.C  【解析】主旨大意题。本文第三段中                Green buildings use less energy, water, 

      create less waste, and are healthier to live, work, or go to school in than 

      standard buildings. Green buildings use resources more properly during the 

      entire building cycle than traditional building.和倒数第二段第一句        Green 

      roofs are another feature of green houses that reduce energy use and 

      cost.倒数第一段第一句        Other features of green buildings often include 

      energy and water conservation, recycling, and waste reduction.可知本文主要

      讲述的是    Green buildings 的很多的好处和特征。故          C 正确。


3.C 【解析】推理判断题。根据第四段第一句                  The environmental benefits of building 

      green include the protection of ecosystems(生态系统)and biodiversity, 

      improved air and water quality, less waste flowing into streams, and the 

      protection of natural resources.由此可知,建造绿色建筑时必须考虑生态系统。

      故选  C。

4.D 【解析】细节理解题。根据倒数第二段                 These roofs are partly or completely 

      covered with plants, which helps to keep heating and cooling costs, prevent 

      water running off and deal with pollutants.可知,他们可以帮助控制大楼里的温

      度。故选    D。
