答案     Wind Energy
    People have been exploiting the wind’s power for a long time. / Today, we capture the wind’s energy with modern windmills. / Such a windmill consists of a tall tower with several blades at the top, / which are caused to spin by the wind. / Then the blades turn a generator located inside the tower to create electricity. /
    Groups of modern windmills are known as wind farms. / They can be found near farmland, in narrow mountain passes, and even in the ocean, / where there are steadier and stronger winds. / They can create electricity for nearby homes, schools, and other buildings. /
    Wind power is very efficient / and it is a clean form of energy. / But the wind is not always a steady source of energy. / Wind speed changes constantly, / depending on the time of day, weather, and geographic location. / Thus it has not yet been used to provide electricity for all our power needs. /

解析     风能
   人们利用风能已经有很长一段时间了。如今,我们利用现代风车来获取风能。这样的风车由一个顶部带有几块叶片的高塔构成,风会引起叶片转动,然后叶片带动塔内的发电机发电。成批运作的现代风车被称为风力发电场。在农田附近、在狭窄的山道里甚至在海洋中都能看到它们。这些风力发电场能为附近的家庭、学校和其他建筑发电。
