范文：Nowadays, the maps of cities are updated frequently. With thedevelopment of city, more and more suburbs become parts of the city. When thecities in the world are amplifying constantly, people discuss the topic hotly,the causes and consequence of the enormous cities. Different people havedifferent answers by their respective views.

In my opinion, the evolution of society and the development of economyresult in the growth of the vast size of cities. Since the number of populationin every city is increasing continually, people need a large amount of space tolive in. With the progress of the technology, the output of crops rises sharply.Fewer and fewer farmers are required, as a result, more and more villagesurbanize. The growth of the cities brings us many huge changes.

There are more job opportunities in the cities. For instance, China willhold the Olympic Games in Beijing in 1008. The government is amplifying the sizeof Beijing to build new gyms in order to hold it excellently. Obviously, peoplein the cities could gain a lot of new jobs.

Of course, the enormous size of cities also has bad effects. Pollution isbecoming more and more serious all over the world with the amplification of thecities. For example, the poisonous gas sent off by factories and automobiles hasmade the air unhealthy for people to breathe. Water waste keeps pouring intorivers and lakes; as a result, many water species are dying 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 clearlywith the reasons why the size of the cities has grown enormously and what itwill bring us. Thus, we could make full use of the positive effects and overcomethe negative effects.
