大作文：Young people are leaving their homes from rural areas to study or work in the cities.What are the reasons?Do the advantages of this development outweigh its disadvantages?
It is true that young generation tends to choose the big cities to be settled instead of living in their houses from remote areas. There are a variety of reasons to explain this problem, in my opinion, these are outweighed by the drawbacks of this trend.
There are two prime causes that lead to urban migration of young adults. Firstly, they have countless opportunities to seek a good job in the city, especially the developing cities where new-established companies would recruit a huge number of employees. Thus, migrated workers could reach a higher standard of living to fulfill their families’ needs. Secondly, most of the universities are located in the cities and these universities attract the ambitious students who want to earn higher degrees. And there are numerous universities for students to choose in terms of many fields of study like banking, technology, and economy. Plus, today’s youngsters would be much maturer to live independently through the vital soft skills stressed during their growth.
However, I believe that there are great disadvantages to be gained. One reason is that the developed cities would deal with harmful problems such as traffic jam, population explosion, and pressure on infrastructure and services. In a densely populated city, if commuters drive out at peak hours, pollution cannot be alleviated by overusing private vehicles, which also hits the cities’ infrastructure severely. In addition, a widening gap between urban areas and countryside makes people living in rural areas feel dissatisfied and unfair. This migration leaves the rural dwellers abandoned and demotes some necessary professions such as farming.
In conclusion, it is no doubt that living in a big city is a good chance for young people in regard to educational opportunities and personal life, I would argue that this tendency has more negative impact on society than positive effects.
