The table demonstrates the features of the underground railway systems in 6 cities in threedifferent aspects.
First, the subway systems in the six cities were opened in time sequence with Londonbeing the earliest (in 1863) and Los Angeles the latest ( in 2001 ). The underground railwaysystem had their prime time in the 20th century, which saw the construction of 4underground railway systems respectively in Paris (1900), in Tokyo (1927), in Washington DC(1976), and in Los Angeles (1981).
学习啦在线学习网 Second, seen from London to Los Angeles, which happened to be in chronological orderof subway construction, the above-mentioned six cities roughly revealed a trend of sharpdecrease in the length of the subway route. London ranked No. 1 in this respect, with a lengthof 394km; Paris came next with 199km; Tokyo was No. 3 with 155km; Washington DC rankedNo. 4 with 126 km. Kyoto and Los Angeles were the most interesting, with merely 11km and28km respectively, nothing comparable with the top 4 cities.

Tokyo took the lead with 1.927 billion; Paris camenext with 1.191 billion; London was No. 3 with 775 million; Washington DC was No. 4 with 144million. Los Angeles and Kyoto had 50 million and 45 million respectively. Therefore, we can seethe big difference as compared with other cities.

学习啦在线学习网 Nowadays, the maps of cities are updatedfrequently. With the development of city, more andmore suburbs become parts of the city. When thecities in the world are amplifying constantly, peoplediscuss the topic hotly, the causes andconsequence of the enormous cities. Different people have different answers by theirrespective views.
In my opinion, the evolution of society and the development of economy result in thegrowth of the vast size of cities. Since the number of population in every city is increasingcontinually, people need a large amount of space to live in. With the progress of the technology,the output of crops rises sharply. Fewer and fewer farmers are required, as a result, more andmore villages urbanize. The growth of the cities brings us many huge changes.
There are more job opportunities in the cities. For instance, China will hold the OlympicGames in Beijing in 2008. The government is amplifying the size of Beijing to build new gyms inorder to hold it excellently. Obviously, people in the cities could gain a lot of new jobs.
Of course, the enormous size of cities also has bad effects. Pollution is becoming more andmore serious all over the world with the amplification of the cities. For example, thepoisonous gas sent off by factories and automobiles has made the air unhealthy for people tobreathe. Water waste keeps pouring into rivers and lakes; as a result, many water species aredying out. Furthermore, more people the city have, more rubbish we can find.
In a word, since each coin has two sides, we should be acquainted clearly with the reasonswhy the size of the cities has grown enormously and what it will bring us. Thus, we could makefull use of the positive effects and overcome the negative effects.
雅思大作文范文：城市扩张相关介绍
It has been argued that urban sprawl is the rootof many environmental problems. Today, I amoffering my viewpoint on this issue and reasons tosupport my position. What is urban sprawl? Urbansprawl is defined as "the increased use of urbanizedland by fewer people than in the past" .In the past, cities were compact and efficient butrecently the density of land utilized per person hasseen a major decline in the United States. From 1982-1997, the United States population hadgrown by about 17 percent, while the urbanized land had increased by about 47 percent duringthe same period in time. Developed land per person has just about doubled in thelast two decades and the sizes of housing lots larger than ten acres can account for over half ofthe land that was developed since 1994.This drastic change in urbanized areashas been met by both environmental impacts, as well as financial and time burdens on thepeople.
One of the most affected environments would be America's farmlands. Farmlands are beinglost due to the creation of new highways, fringe industrial parks, and new sprawled housingdevelopments.The loss of farmlands reduces our ability to produce food, fiber,and timber. Further, the higher tax rates and costs that are associated with urban sprawl areforcing many farmers to close down business and sell their farms to companies seeking todevelop new housing areas, as a means to secure their financial security.Thisproblem has highly affected the state of Wisconsin. In 1950, Wisconsin had roughly about23.6 million acres of farmland and as of 2002 only had about 16 million acres. Along with thisreduction in farmland area, the number of farms in Wisconsin decreased from 178,000 to77,000 from 1910 to 2002.This decrease in farmland is not only seen inWisconsin but also the rest of the country. Between 1992 and 1997, the nation converted morethan 13.7 million acres of farmland to urbanized areas.
学习啦在线学习网 Along with the loss of farmland, there is a loss of wildlife habitats that are disappearing dueto urban sprawl. These forests, meadows, and wetlands are disappearing and beingsubstituted with pavement, buildings, and sterile urban landscaping. This loss of wildlifehabitats make it hard for species to survive and makes it difficult for them to find suitablebreeding ponds, hibernation sites, feeding locations, and to create practical nesting areas. The urban sprawl has been so bad in some places that species of plants arebecoming nearly extinct. For example, the Oak Savannas and the Oak and Pine Barrens bothhave been degraded to the point that there is less than 1 percent of the original species stillaround .
Urban sprawl has contributed greatly to air and water pollution as well as increased waterand energy consumption. Since urban sprawl places people outside of walking distance toshopping areas and work areas, they are forced to rely heavily on cars to get from point A topoint B. This over reliance on vehicles has contributed significantly to air pollution andgreenhouse gases.Pollution from vehicles is usually the number one cause ofpollution in many urbanized cities, such as Los Angeles. Another thing to think about would bethe recent heat waves that have been experienced in the past month across the nation. Peoplefail to realize that urban sprawl and pollution, which is a by-product of urban sprawl, havecontributed significantly to the high temperatures this summer.Urban sprawlincreases the amount of concrete and asphalt, thus holding in the heat and making it evenwarmer than it would have been had sprawl not occurred. Another part of this would be thatthe pollution leads to higher levels of humidity in the air and in turn exaggerates the effects ofgreenhouse gases.
雅思大作文范文：摩天大楼
学习啦在线学习网 Nowadays, with a growing number of high-tech buildings that look alike, cities across the planetare becoming more and more similar. Apparently for better rather than for worse, theseskyscrapers may be seen as a reflection of the a single architectural culture in the making in aworld increasingly being globalized. The sameness, however monotonous or boring, must beregarded as inevitable since most designs of those high-rises are functionally oriented totackle the reality of the increasingly dynamic societies.
Why do urban buildings have to grow in height and why are most of them having almostidentical outlooks which are not very unlike cardboard boxes? Ironically, an easy answer is:'why not'? To begin with, in many booming cities there are not only urgent needs ofconstructing tall buildings to meet the demand of expanding urban populations, but also high-tech ways and means to do it. Further, many old buildings , which used to be out of orders atbest and dangerous at worst, had necessarily to be demolished, thus making room forskyscraper constructions. This is a good thing, considering that modern buildings canfunction more efficiently and effectively, and at the same time can house more people forworking or living. Likes or dislikes, tall towers that look awfully similar will be the future in bigcities.
Nevertheless, what could be wrong about cities becoming more and more similar? Onedisadvantage is that, when people travel beyond borders, they are probably not expected toexperience differences between one place and another because the landscapes of modern citiesmay look very much alike over the horizons. And so what? On the one hand, these same peoplealso eat out in standardized fast-food outlets, such as MacDonald's, Kentucky Fried Chicken orPizza Hut, but do not seriously complain about being bored by the same food. Strangely, whyon the other hand they should disagree with new buildings getting tall in similar fashions? Is itnot as if they might think that today's new buildings should look old enough to becomedifferent?
After all, the modern-age reality in cities is dynamic, so the space people work or live in oughtto be dynamic as well. New buildings, particularly skyscrapers, are designed and constructedto adjust to the continuous change in the right direction, and to follow the nature of newsocieties. In short, when cities are becoming more and more alike, they are also becoming morealive.
