标题:风车的历史和功能
风车是一种古老而有趣的工程装置,具有丰富的历史和多种功能。在过去的几个世纪里,风车已经成为了人们生活中不可或缺的一部分。本文将探讨风车的历史和功能。
首先,风车的历史可以追溯到几千年前。早在公元前2000年左右,中国就已经开始使用风车来灌溉农田。随着时间的推移,风车传播到了欧洲和其他地方,被用于磨面粉、提供动力等各种用途。通过使用风能,人们能够更高效地完成各种任务,提高生产力和生活质量。
其次,风车有多种功能。最常见的是风车被用来发电。通过将风的动能转化为机械能,然后再转化为电能,风车成为了一种可再生能源的重要来源。在如今的世界,越来越多的国家和地区使用风力发电来减少对传统能源的依赖,保护环境。此外,风车还可以用于水泵、排水和空气循环等方面。在农村地区,风车常常被用来提供给水和发电,满足基本的生活需求。
最后,风车在旅游业中也扮演着重要的角色。许多国家和地区都有著名的风车景点,吸引着大量的游客。例如,荷兰的风车村景区和西班牙的拉曼恰风车公园都是备受游客喜爱的旅游胜地。这些风车不仅展示了传统的建筑风格,还向游客展示了风车的工作原理和历史背景。
总之,风车作为一种古老而有趣的工程装置,具有丰富的历史和多种功能。它不仅在发电领域发挥着重要作用,也成为旅游业中的热门景点。无论是过去还是现在,风车一直在为人类的生活和发展做出贡献。

标题:风车的环保意义
随着全球气候变化和环境污染的加剧,可持续发展和环保已经成为当今社会的重要议题。在这方面,风车作为一种可再生能源装置,具有重要的环保意义。本文将探讨风车的环保意义和影响。
首先,风车是一种清洁能源的重要来源。与传统能源相比,如煤炭和石油,风能是一种无污染的能源形式。通过将风的动能转化为电能,风车不会产生任何二氧化碳和其他有害气体的排放。这对于减少温室气体的排放,缓解气候变化非常重要。
其次,风车有助于减少对传统能源的依赖。传统能源的开采和使用对环境造成了严重的破坏,如空气和水污染、土地破坏等。通过广泛使用风力发电,我们可以减少对煤炭、石油等有限资源的需求,降低对环境的负面影响。
此外,风车的建设和使用也能够创造就业机会,促进经济发展。风力发电产业的兴起为创造大量的工作岗位提供了机会,如风车制造、安装和维护等。这不仅有助于提高就业率,还为经济带来了新的增长点。
最后,风车的环保意义还体现在其可持续性上。与化石燃料相比,风能是一种永无止境的能源形式。风永远不会枯竭,而且在许多地方都很充足。因此,通过利用风能,我们可以实现能源的可持续利用,为未来的世代提供清洁的能源来源。
总之,风车作为一种可再生能源装置,具有重要的环保意义。通过利用风能发电,我们可以减少对传统能源的依赖,降低温室气体的排放,促进经济发展和创造就业机会。同时,风能也是一种可持续的能源形式,为未来的能源需求提供了可靠的解决方案。因此,风车在环保领域的作用不可忽视。

The chart below shows the total number of Olympic medals won by twelve different countries.
The bar chart compares twelve countries in terms of the overall number of medals that they have won at the Olympic Games.
It is clear that the USA is by far the most successful Olympic medal winning nation. It is also noticeable that the figures for gold, silver and bronze medals won by any particular country tend to be fairly similar.
The USA has won a total of around 2,300 Olympic medals, including approximately 900 gold medals, 750 silver and 650 bronze. In second place on the all-time medals chart is the Soviet Union, with just over 1,000 medals. Again, the number of gold medals won by this country is slightly higher than the number of silver or bronze medals.
Only four other countries - the UK, France, Germany and Italy - have won more than 500 Olympic medals, all with similar proportions of each medal colour. Apart from the USA and the Soviet Union, China is the only other country with a noticeably higher proportion of gold medals (about 200) compared to silver and bronze (about 100 each).

The diagram below shows how solar panels can be used to provide electricity for domestic use.
The picture illustrates the process of producing electricity in a home using solar panels.
It is clear that there are five distinct stages in this process, beginning with the capture of energy from sunlight. The final two steps show how domestic electricity is connected to the external power supply.
At the first stage in the process, solar panels on the roof of a normal house take energy from the sun and convert it into DC current. Next, this current is passed to an inverter, which changes it to AC current and regulates the supply of electricity. At stage three, electricity is supplied to the home from an electrical panel.
At the fourth step shown on the diagram, a utility meter in the home is responsible for sending any extra electric power outside the house into the grid. Finally, if the solar panels do not provide enough energy for the household, electricity will flow from the utility grid into the home through the meter.

I am writing to inform you that the microwave oven in your kitchen is broken. I am so sorry and it was all my fault.
This morning, when I was cooking my breakfast, I put the utensil which is made from metal into the machine. Unfortunately, after few seconds, I saw sparks flying off and heard two or three loud bangs. I was too scared to cut off the electricity immediately. While I opened the oven, there were some holes in the internal surface and the bulb was smashed. Obviously, it can not work any longer.
I was so hurry for work at that time that I forgot the notice of how to use the microwave oven appropriately. I made a sincere apology to you for my mistake and hope you could contact with the workers who can repair the damage. I promise I would pay for the maintenance costs.

The maps given compare the current layout of a college with its plan in 2015.
At present, to the north of the rectangular campus there is a garden opposite to the entrance. Along the west wall lie a footpath and a car park and the south a bus stop. Inside, two classrooms in the south and a bigger one in the northeastern corner can be found, on the south of which the reception and the library are sited. Not mentioned are the seemingly open area for lunch in the northwestern and the toilets in the south.
The college in 2015 is expected to demonstrate many differences including its extended length, along with which the car park will also expand its size. The garden and the footpath will vanish while a shop will be introduced inside. Noticeably, the entrance and the toilets will exchange their places, with the former directly leading to an oval reception. Likewise, the library of a shrunk size will be moved to the southwestern corner where a classroom lies now. Along the east wall four classrooms will be located.
Despite the differences, that all the facilities are built immediately adjacent to each other and against the wall will remain consistent.
