    The success of green energy depend upon the ability to extract harmful by-products from______.
    A:global warming
    B:carbon emission
    C:lower waste output
    D:a green energy source
    E:fossil fuels
    F: clean fuels

    答案：E
    解析：
    文中第一段第一句中Green energy is energy that is…这种表述方法符合科学说明文的记叙方式，首先对一个名词进行科学定义，所以本题答案为D。
    文中第二段第二句：Every form of energy collection will result in some pollution, but those that are green are known to cause less than those that are not．任何形式的能源收集都会产生一定程度的污染，但是绿色能源比其他能源造成的污染要少。可以推测出这一段是在讲绿色能源的优点，也就是说为什么要发展绿色能源，所以选择A。
    文中第三段第一句：It is not completely necessary for green energy sources to come from places like solar or wind fields．可以得出，本段主要讲述了我们传统认为的新能源，还有其他种类的新能源，所以选择F。
    文中第四段第一句：One of the goals of green energy technology is to take existing fossil fuel energy technology and clean it up so it is produced more cleanly．可以得出，该段主要是在讲新能源的目标和意义。
    第一段最后一句：There are several more, even including nuclear energy, that is sometimes considered a green energy source because of its lower waste output relative to energy sources such as coal or oil．可知，核能经常被视作绿色能源，因为相比煤和石油，它的能源输出效率更高。由此可以得出选项C正确。
    文中第二段最后一句：Greenhouse gases, a by-product of traditional sources of energy such as fossil fuels are thought to be causing global warming,or the process of the Earth heating up at an accelerated pace.温室气体，一种诸如化石能源的传统能源产生的副产品被认为会导致全球变暖，甚至使地球自转速度加快。因此可以得出A选项正确。
    第三段最后两句：The conservation of energy through architectural design becomes,itself,a green energy source .Similarly,many sources of green energy can come directly from the area in which the energy is needed rather than from an outside source．通过自身的建筑设计来保存能源本身就是一种绿色能源的来源。同样道理，许多绿色能源可以直接来源于有能源需求的地区内部而不是外部。由此可以得出D选项正确。
    最后一段最后两句：The success of such these types of green energy depend upon the ability to extract harmful by-products from fossil fuels while not only being energy efficient, but by being cost efficient as well．这些清洁能源技术的成功取决于人们从化石燃料中排除有害副产品、高效利用能源、同时降低成本的能力。由此可以得出E选项正确。
