3. 规定情景式作文：
Directions: Migrant workers (外地民工) have made a great contribution to the prosperity of cities. In this part, you are to write an essay of 200 words entitled "The Role of Migrant Workers". You can agree and/or disagree, completely or partially to above statement. But no matter which position you take, you should give sound supporting reasons.
As is known to all, migrant workers have made a great contribution to the prosperity of cities. They are an indispensable part of our work force. Most of them work on construction sites. There is no doubt that without migrant workers many of the construction projects would have to be held up for lack of manpower. In addition, a large number of migrant workers are a beneficial factor, which enhances the consumption of food and daily items. This in turn helps to develop food industry and service trades in cities. 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. Firstly, most of them are not well educated and professionally trained. Some of them have had very little schooling. As you know, illiterate people, who are usually ignorant of the law, tend to disturb the peace, endangering social order. Secondly, most of the migrant workers swarm into big cities just to make money. Being illiterate or unskilled, some of them would stop at nothing to get what they are ambitious for. Therefore, they are a potential threat to the peace and stability of 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. (244 words)
注：disturb the peace 扰乱治安。would stop at nothing to do sth. 不择手段做某事。
