英語(yǔ)四級(jí)命題作文：農(nóng)民工的作用

The Role of Migrant Workers
　　As is known to all, migrant workers have made great contributions to the prosperity of cities. They are an indispensable part of our workforce. There is no doubt that many construction projects would be lack of manpower without them. In addition, a large number of migrant workers stimulate the consumption of food and daily items. All these are positive aspects of migrant workers in cities.
　　However, as a popular saying goes, "Everything has two sides". The same is the case with migrant workers. First, they have trouble getting their children into child care centers and schools because they are unregistered residents in the city. Second, most of the migrant workers swarm into big cities just to make money. Being not well-educated and incompetent, they are a potential threat to the peace and stability of the society.
　　In my opinion, in the appraisal of migrant workers, it is one-sided to affirm everything or to negate everything. We should appreciate the great contribution made by them, and at the same time pay enough attention to the problems caused by them.                (178 words)
