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.
