¡¡¡¡Nowadays£¬ the maps of cities are updated frequently. With the development of city£¬ more and more suburbs become parts of the city. When the cities in the world are amplifying constantly£¬ people discuss the topic hotly£¬ the causes and consequence of the enormous cities. Different people have different answers by their respective views.
¡¡¡¡In my opinion£¬ the evolution of society and the development of economy result in the growth of the vast size of cities. Since the number of population in every city is increasing continually£¬ 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 and more 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 Olympic Games in Beijing in 2008. The government is amplifying the size of Beijing to build new gyms in order 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 and more serious all over the world with the amplification of the cities. For example£¬ the poisonous gas sent off by factories and automobiles has made the air unhealthy for people to breathe. Water waste keeps pouring into rivers 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 clearly with the reasons why the size of the cities has grown enormously and what it will bring us. Thus£¬ we could make full use of the positive effects and overcome the negative effects.£¨ÒÔÉÏ·¶ÎÄÓÉÉϺ£Ð¶«·½ÃûʦÕųÛÐÂÌṩ£©
