                                                         Make the benefits most,

                                                 reduce the drawbacks (缺点) least

     Hosting the Olympics successfully is, perhaps, the greatest glory for a city. However, before turning the

dream into reality, the benefits and drawbacks of hosting the Olympics should be considered carefully.

     Hosting the Olympics surely would bring about much gain to a city. Boom (繁荣) of the local economy,

more jobs, and the possibrlity ofmore income all sound very attractive to the govemment. At the same time,

better infrastructure (基础设施), cleaner environment, enjoying the wonderful game with hundreds of sports

elites (精英)and entertainment stars, and the chance of contacting people from all over the world also seem

exciting to the citizens. Besides, the hosting will certainly promote the patriotic (爱国的) emotion and pride,

as well as the moral behavior in local people. In most cases, hosting the Olympics is well supported by both

the pubiic and the central government.

     But this is not the entire view of the pretty picture. If we look from another angle, the Olympic hosting

might bring about some side-effects to a city.

     First, the environmental impacts, including the increasing exhaust (排气) smoke of cars, more pressure

on water resources, huge amount of wasted leaflets and other materials used for public activities, are most

probably neglected. In order to broaden the streets, some trees may have to be cut. Near the construction

site, the tiny dust may float in the air for a long time. Reduction of farmland may be caused by the need of

setting up new sports centre or accommodation facilities. These environmental consequences (后果) can be

especially serious in a resource-limited and thickly-populated city in a third-world country. Second, if we talk

about the economic benefit, it should not be forgotten that a quick increase may lead to bubble (泡沫) growth,

which may easily crash. If not well managed and organized, the big event may not be so profitable, and the

new facilities may be forever empty after the games. Yes, there have been cases that host cities ended up with

enormous debts.

     No one stops eating merely because too much food might hurt his stomach and make him ill. Since we

have bid for it,what we can do is to make the benefits most and reduce the drawbacks least.

                              Title: Make the benefits most, reduce the drawbacks least
