Clean energy has been given greater prominence than ever before; it is seen as a new industrial【C3】______and【C4】______of economic growth for the new century. The time for clean energy has come.
    In China, clean energy is moving ahead at full speed. Take wind power as an example: China had【C5】______wind power generating capacity of 12.21 GW, making China the largest wind power generator in Asia and fourth in the world. But according to the research, one-third of wind power capacity is running【C6】______due to an inability to get the power to the national【C7】______.
    India-like China—relies【C8】______on coal for its energy needs. This will only change if the funds and technology to develop clean energy, such as wind and nuclear power, are【C9】______. India will not choose clean energy【C10】______. Nuclear power is currently the most【C11】______of clean energy sources.【C12】______, if it is to be【C13】______on a large scale by developing nations, technological advances will be needed to make it competitive with coal.
    Compared【C14】______developed countries, developing countries have more【C15】______choices when it comes to energy structure. Promoting economic growth requires【C16】______energy—and coal, the cheapest and most【C17】______source of energy for many countries—is the【C18】______choice. Cheap coal means cheap electricity and a competitive economy. Rising electricity prices would cause public【C19】______and impact on standards of【C20】______.
【C4】
选项 A、resource
B、reason
C、root
D、source
答案D
解析 resource“资源、资料”；reason“原因”，表示“…的原因”时，用介词for，比如，She gave no reasons for her decision．她没有对她的决定做出任何解释。root主要指一个问题的根源、起因，比如，What lies at the root of his troubles is a sense of insecurity．他的一切忧虑源于一种不安全感。source“起源、源头、根源、原因”。本句的意思是清洁能源成为新世界经济增长的源头，选项A。B和C均不适合。所以，本题选择D。
