Passage 1 Solar energy（太阳能）
Solar energy is lauded as an inexhaustible fuel source that is pollution and often noise free. The technology is 
also versatile. For example, solar cells generate energy for far-out places 41.like satellites in Earth orbit  and
 cabins deep in the Rocky Mountains as easily as they can power downtown 42.buildings and futuristic cars. 
But solar energy doesn't work at night without a storage device 43.such as batteries, and cloudy weather can make the technology unreliable during the day. Solar technologies are also very expensive and require a lot of land area 44.to collect the sun's energy at rates useful to lots of people. 
Despite the drawbacks, solar energy use has surged at about 20 percent a year over the past 15 years, thanks to rapidly falling prices and gains in efficiency. Japan, Germany, and the 45.United States are major markets for 
solar cells. With tax incentives, solar electricity can often pay for itself in five to ten years. 
（41） C. like satellites in Earth orbit 像地球轨道上旳卫星
（42） A. buildings and futuristic cars 建筑和未来旳汽车
（43） B. such as batteries 例如电池
（44） D. to collect the sun's energy 搜集太阳旳能量
（45） E. United States 美国

Passage 2 According to the mode of energy conversion根据能量转换模式
According to the mode of energy conversion, power pants can be classified into fossil-fired, hydraulic, 46nuclear, wind, solar, geothermal, tide power plants, and so on.
A power plant transforms primary energy source into electric power and 47supplies power to users.
A co-generation plant is the power plant that not only generates electricity but also 48supplies steam to the user.
Normally, in selecting the site of a new power plant, following factors should
