荷兰传统风车四叶扇,其他都是三叶

A windmill is a machine that is powered by the energy of the wind.It is designed to convert the energy of the wind into more useful forms using rotating blades or sails.The term also refers to the structure it is commonly built on.In much of Europe,windmills served originally to grind grain,though later applications included pumping water and,more recently,generation of electricity.Recent electricity-generating versions are referred to as wind turbines.
Windmills have always played a great part in the life of Holland and its inhabitants.While at first they served to grind corn,to remove excess water from the low-lying districts,and to saw timber,thus making the country fit for human habitation and adding to habitable area,they developed - especially in the seventeenth century - into a most important factor in the social structure of those days.It is with increasing interest that one learns about this.
Although it can be said that windmills which can be compared with the Dutch windmills are to be found in other European countries as well (England,Belgium,France,Denmark,Germany,Finland),it has to be observed that their number is relatively small there.It is only in Holland that so many windmills are present in so small an area.These windmills moreover are in very reasonable,many of them even in excellent,condition and a considerable number of them are working regularly.There are windmills of the most varied types:drainage mills,corn mills,and industrial mills for all sorts of purposes.
Windmills form an important element in the Dutch landscape with its wide horizons,its glittering waters and big clouds floating overhead; without them we can hardly imagine this landscape,which is unique in the world.
The following pages will show these windmills from the aesthetic,the historical,and the technical point of view.We hope they may help to deepen the fascination which windmills exert on the spectator,and to add to the pleasure of seeing them in their own natural surroundings.
'The wind bloweth where it listeth,and thou hearest the sound thereof,but canst not tell whence it cometh,and wither it goeth:so is every one that is born of the Spirit.'
