帮我SAT作文评分谢谢!Do you agree that progress is always positive?
Everything has its second fold.Progress is not an exception.We define progress as a process of development,with overcomes,victories and milestones on the road behind.However,the value of progress is assessed by the impacts made from the road.Such impacts involve both positiveness and negativeness.The following context will be discussing two negative examples that are influenced by progress.
The Industrial Revolution is widely confirmed to be a dramatic turning point in human history,setting up ample scientific and manufacturing milestones during the 18th and 19th centuries.Factories with smokestacks were established everywhere,thus accelerated the productivity with more efficiency.It was also significant that the progress of railway transportation connected people and business together.Nevertheless,judging from another angle,the revolution saw the severe pollution in industrial cities.Moreover,continuously exhausting carbon dioxide into the atmosphere caused the threat to the eco-system-the Greenhouse Effect.Therefore,to some extent,the progress turned to drawback in some areas.
The second example is about overpopulation.The population has increased rapidly over the last 50 years.Since 1950s,the growing rate has already risen to 1.8%per year.What impulsed the boom was the developing of advanced medical techniques that lowered the mortality rate.This is a trememdous progress,leading to longevity of human beings.Notwithstanding we all embrace the highly-developed world,the fact of overpopulation let us to mitigate the rate and cease the boom.Overpopulation is a generally undesirable condition where human beings exceed the carrying capacity of the habitat.If this keeps up,there will appear the depletion of natural resources,the changes in atmosphere composition turning to consequent global warming,and the starvation,malnutrition or poor diet in poor countries.The progress of one thing has a link-reaction with a series of other things.Hence,it is too arbitrary to proclaim that all progresses are completely positive.
In conclusion,afer analysing the above examples of twofold progress,can we say progress is always positive?No.But,the ambition to improve cannot be thrown away.Progress is still very essential.
