The Windmill 风车

　　In the Netherlands, we see a lot of buildings with huge wings. 在荷兰，我们会看到很多有巨大风翼的建筑。

　　What are they? They are not houses, they're windmills. 它们是什么？它们不是房子，而是风车。

　　The Netherlands and many other countries build windmills. 荷兰和许多其他国家都有风车。

　　Most windmills have four wings. 大多数风车有四个风翼。

　　These wings are called blades. 这些风翼叫做风叶。

　　When the wind blows, the four blades on a windmill move around. 刮风时，风车上的四个风叶会转动。

　　With the machine in the windmill, people can light up their houses and do a lot of things. 人们利用风车的这个装置来照明和做许多其他的事。

　　The machine works better if the weather is windy. 如果是有风的天气，风车会工作得更好。

　　So you see windmills often in a windy city. 所以你在有风的城市经常能见到风车。
