However, the author's argument relies on a series of unsubstantiated assumptions, and is
therefore unpersuasive as it stands.
One problem with the argument is that it assumes that the nationwide statistics about the
incidence of sports injuries among youngsters applies equally to Parkville's children. Yet this
might not be the case, for a variety of possible reasons. Perhaps Parkville maintains more
241
stringent safety standards than the national norm; or perhaps children's sporting events in
Parkville are better supervised by adults, or supervised by more adults. Without ruling out such
possibilities, the author cannot justifiably conclude that Parkville has a sports-injury problem to
begin with.
A second problem with the argument is that it unjustifiably assumes that in Parkville parents
and coaches unduly pressure youngsters to win organized athletic competitions. The only
evidence the author provides to substantiate this assumption are the reports from "big city"
children. We are not informed whether ParkviUe is a big city. Perhaps people who live in big
dries are generally more competitive than other people. If so, and if Parkville is not a big city,
then the author cannot justifiably rely on these reports to conclude that the proposed course of
action is necessary.
A third problem with the argument is that it unfairly assumes that children do not benefit
academically from participating in competitive sports. It is entirely possible that such sports
provide children with the sort of break from academics that helps them to be more productive
academically. It is also possible that the competitive drive that these sports might instill in
young children carries over to their academics and spurs them on to perform well in school.
Without considering such potential academic benefits, the author cannot reasonably conclude
that for young children the disadvantages of participating in athletic competition outweigh the
benefits.
In conclusion, the argument is unconvincing as it stands. To better evaluate the argument
we would need more information about the incidence of sports injuries among young children
in Parkville. To strengthen the argument the author must demonstrate that ParkviUe's parents
and coaches exert the kind of pressure on their children reported by "big city" children and, if
so, that this pressure in fact contributes to the sort of problems with which the author is
concerned.
Argument 92
It is known that in recent years, industrial pollution has caused the Earth's ozone layer to thin,
allowing an increase in the amount of ultraviolet radiation that reaches the Earth's surface. At
the same time, scientists have discovered, the population of a species of salamander that lays
its eggs in mountain lakes has declined. Since ultraviolet radiation is known to be damaging to
delicate tissues and since salamander eggs have no protective shells, it must be the case that
the increase in ultraviolet radiation has damaged many salamander eggs and prevented them
from hatching. This process will no doubt cause population declines in other species, just as it
has in the salamander species. 感谢您阅读《GRE作文范文大全(137) 》一文,出国留学网(liuxue86.com)编辑部希望本文能帮助到您。
