In recent years, more and more migrant workers have moved into big cities and they have been making great contributions to the development of cities. New buildings need them, roads can't be repaired without them, and the planting and protecting of trees and flowers depend on them. Indeed, they play an important role in the construction of cities in China today.
近年来，越来越多的农民工已经搬到大城市，他们为城市的发展做出了巨大的贡献。新的建筑物需要他们，没有他们道路无法修复，种植保护树木、花草依靠他们。事实上，在今天中国的城市建设中他们发挥了重要的作用。
However, they have brought about some problems. The biggest one is the increase of the city population. The once crowded cities have now become more crowded. And their arrival may cause a serious crisis in housing, water and other resources. In addition, they have taken so many jobs that the labor market in cities has become even weaker. What's more, some of the farmland is left uncultivated as a result of the farmers' emigration.
然而，他们也带来了一些问题。最大的一个是城市人口的增加。曾经拥挤的城市现在已经变得更拥挤。他们的到来可能会引起严重的房屋，水和其他资源危机。此外，他们已经接管了很多的工作，使得城市劳动力市场变得更弱。更重要的是，由于农民移民一些耕地被荒废了。
In my opinion, migrant workers' contributions outweigh the inconveniences they bring us. On the whole, they have become an important part of our socialist builders. Nevertheless, the government should work out new policies to control the emigration of farmers on the one hand and to protect migrant workers' rights and interests on the other hand.
在我看来，农民工的贡献大于他们给我们带来的不便。总体上，他们已经成为我国社会主义建设者的重要组成部分。然而，一方面政府应该制定新政策来控制农民移民和另一方面保护农民工的利益。
