Cloning 一、閱讀理解 Pollution’s great effects on the environment have bee 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（維護）and demolition（拆毀）—than those who construct more regular buildings. The environmental benefits of building green include the protection of ecosystems（生態(tài)系統(tǒng)）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（微風）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 pletely 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 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的諸多好處和對環(huán)境的巨大的保護作用，呼吁人們多建設這樣的綠色的建筑。 1.C 【解析】主旨大意題。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.和倒數(shù)第二段第一句Green roofs are another feature of green houses that reduce energy use and cost.倒數(shù)第一段第一句Other features of green buildings often include energy and water conservation, recycling, and waste reduction.可知本文主要講述的是Green buildings的很多的好處和特征。故C正確。 3.C 【解析】推理判斷題。根據(jù)第四段第一句The environmental benefits of building green include the protection of ecosystems（生態(tài)系統(tǒng)）and biodiversity, improved air and water quality, less waste flowing into streams, and the protection of natural resources.由此可知，建造綠色建筑時必須考慮生態(tài)系統(tǒng)。故選C。 4.D 【解析】細節(jié)理解題。根據(jù)倒數(shù)第二段These roofs are partly or pletely covered with plants, which helps to keep heating and cooling costs, prevent water running off and deal with pollutants.可知，他們可以幫助控制大樓里的溫度。故選D。 二、教材與語法填空 根據(jù)教材課文內容，在空白處填入1個適當?shù)膯卧~或括號內單詞的正確形式。 Cloning is a way of making an exact copy of another animal or plant.
