一、田野里的大风车是干嘛用的？
田野的风车通常是风力发电，为把风的动能转为电能。风能是一种清洁无公害的的可再生能源能源，很早就被人们利用，主要是通过风车来抽水、磨面等。风力发电非常环保，且风能蕴量巨大，因此日益受到世界各国的重视。
风车可用于发电和磨麦子，利用风车驱动机械装置，便能把小麦磨成粉，把玉米磨成玉米片
二、风车的寓意 风车相关介绍
1、风车象征着自由与幸福。
2、在中国来传统文化里，又名吉祥轮、八卦风轮、四季平安符。在很多地方都有类似于风车的建筑，也成为了一道亮丽的风景线，在现代企业里风车也代表了事业蒸蒸日上的寓意。
3、风车是风力机将风能转换为机械功的动力机械，它是一种以太阳为热源、大气为工作介质的热能利用发动机；设置地点灵活、成本低，使区域性调节电力输出成为了可能；风电效益相当大程度上取决于安装地点的风力状态，通过气象测量可得到安装地点。
三、风车磨坊的介绍
2000多年前，中国、巴比伦、波斯等国就已利用古老的风车提水灌溉、碾磨谷物，风车的作用主要是将风力转化为桨轮转动得来的动力，从而通过风车利用风能提水、供暖、制冷、航运、发电等，公元8世纪时在中亚已经出现了研磨谷物的风车磨坊。
四、急!!求救一篇介绍荷兰风车的英文!
WINDMILL (MOLEN DE ROOS)
Originally there were 15 windmills within the old defensive walls of Delft, but only one survives today. This is called Molen De Roos (The Rose Windmill). It is located a short walk from the Oude Kerk (Old Church). It was used for grinding grain for bakers and barley, oats and corn for farmers. It needed extensive restoration work between 1988 and 1990, but is now back in full working order. When it is open to visitors a blue flag flies from the top of the windmill. There is no entrance charge, but voluntary donations help the Vereniging De Hollandsche Molen (The Dutch Windmill Association) to maintain the building.
Take a Virtual Windmill Tour of Windmills - by by Peter Melville
Holland is famous for its windmills, so no one will be surprised to learn that the world’s tallest windmills are to be found here. However, few Dutch, let alone tourists, will be able to tell you where they stand. And people might not even believe it when told that they are not out in the fields, but in heart of the most densely populated areas on the globe, near the second largest port in the world.
Schiedam lies to the west of Rotterdam, from where it is easily reached by public transport. Surrounded by 20th-century commercial and residential areas is the small yet charming 18th century town center, looking like a pocket-size Amsterdam. At the western edge of Schiedam’s old center, lined up along the former outer canal, stand the world’s five tallest windmills.
Their location explains their height.
When the windmills were built, between 1770 and 1803, they stood in what was then the edge of town and the industrial area. They were built for the grinding of grain needed for the distillation of gin, then Schiedam’s main industry. To catch as much wind as possible, they were made to stand high above the city, which came to lie at their feet.
In those days the canal was a moat, and the other side of the moat only flat farmland. That area started being built early in the 20th century, and now it is a semi-urban area of little architectural distinction. The result of this development for the windmills is that they are now surrounded by buildings and are part of the urban landscape. The highest windmills in the world stand in the middle of town.
These five windmills are what remain of an original twenty, the others having been made redundant by steam engines. In 1880, those twenty mills ground grain for the nearly 400 distilleries that made the famous jenever of Schiedam, where more gin was produced than in any other city in the world. Schiedam can no longer make that claim, but two of the five remaining windmills do still grind grain for the jenever industry. The blades of the other three windmills still turn as well, but only for show. Three of the five can be visited to see the interior: one houses a shop, one a museum and the third a restaurant.
In 1981 the Schiedam Windmills Society was founded. The Society’s aim is to assist in the operation and maintenance of these unique windmills, which had previously been badly neglected. In celebration of the Society’s 25th anniversary, on April 28 and 29 the blades of all five windmills will turn non-stop for 25 hours.
Let’s take a walk along the five windmills in Schiedam. Join us for the World's Tallest Windmills Virtual Tour.

荷兰座落在地球的盛行西风带，一年四季盛吹西风。同时它濒临大西洋，又是典型的海洋性气候国家，海陆风长年不息。这就给缺乏水力、动力资源的荷兰，提供了利用风力的优厚补偿。
荷兰的风车，最早从德国引进。开始时，风车仅用于磨粉之类。到了十六、七世纪，风车对荷兰的经济有着特别重大的意义。当时，荷兰在世界的商业中，占首要地位的各种原料，从各路水道运往风车加工，其中包括：北欧各国和波罗的海沿岸各国的木材，德国的大麻子和亚麻子，印度和东南亚的肉桂和胡椒。在荷兰的大港--鹿特丹和阿姆斯特丹的近郊，有很多风车的磨坊、锯木厂和造纸厂。
随着荷兰人民围海造陆工程的大规模开展，风车在这项艰巨的工程中发挥了巨大的作用。根据当地的湿润多雨、风向多变的气候特点，他们对风车进行了改革。首先是给风车配上活动的顶篷。此外，为了能四面迎风，他们又把风车的顶篷安装在滚轮上。这种风车，被称为荷兰式风车(如左图)。
荷兰风车，最大的有好几层楼高，风翼长达20米。有的风车，由整块大柞木做成。十八世纪末，荷兰全国的风车约有一万二千架，每台拥有6000匹马力。这些风车用来碾谷物、粗盐、烟叶、榨油，压滚毛呢、毛毡、造纸，以及排除沼泽地的积水。正是这些风车不停地吸水、排水，保障了全国三分之二的土地免受沉沦和人为鱼鳖的威胁。
二十世纪以来，由于蒸气机、内燃机、涡轮机的发展，依靠风力的古老风车曾一度变得暗淡无光，几乎被人遗忘了。但是，因为风车利用的是自然风力，没有污染、耗尽之虞，所以它不仅被荷兰人民一直沿用至今，而且也成为今日新能源的一种，深深地吸引着人们。
目前，荷兰大约有两千多架各式各样的风车。荷兰人很喜爱他们的风车，在民歌和谚语中常常赞美风车。风车的建筑物，总是尽量打扮得漂漂亮亮的。每逢盛大节日，风车上围上花环，悬挂着国旗和硬纸板做的太阳和星星。
