gre写作例子：GRE作文argument210详解

【题目】210 The following is a letter to the editor of a news magazine.
"Clearly, the successful use of robots on missions to explore outer space in the past 20 years demonstrates that robots could be increasingly used to perform factory work more effectively, efficiently, and profitably than human factory workers. The use of robots in factories would offer several advantages. First, robots never get sick, so absenteeism would be reduced. Second, robots do not make mistakes, so factories would increase their output. Finally, the use of robots would also improve the morale of factory workers, since factory work can be so boring that many workers would be glad to shift to more interesting kinds of tasks."

【翻译】显然，过去20年中机器人在探索外层空间任务中的成功使用证明，机器人可以比人类工作人员更有效、更有益地用于进行很多工作。工厂中机器人的使用将带来若干好处。首先，机器人从不生病，从而旷工将会减少。其次，机器人不会出错，因此工厂产量将会增加。最后，使用机器人同样也会提高工厂工人的精神状态，因为工厂工作有时如此枯燥以至于很多工人将会乐于转换到更有趣的任务。

【题目拆析】
论点： Clearly, the successful use of robots on missions to explore outer space in the past 20 years demonstrates that robots could be increasingly used to perform factory work more effectively, efficiently, and profitably than human factory workers. The use of robots in factories would offer several advantages.

论据：
1。First, robots never get sick, so absenteeism would be reduced. 首先，机器人从不生病，从而旷工将会减少。
2。Second, robots do not make mistakes, so factories would increase their output. 其次，机器人不会出错，因此工厂产量将会增加。
3。Finally, the use of robots would also improve the morale of factory workers, since factory work can so boring that many workers would be glad to shift to more interesting kinds of tasks. 最后，使用机器人同样也会提高工厂工人的精神状态，因为工厂工作有时如此枯燥以至于很多工人将会乐于转换到更有趣的任务。

【攻击分析】
论据1:虽然机器人不会生病，但是它也会产生机械故障，停止工作，阻碍生产。错误类比

论据2:
A.机器人也会出错，因为它是有由直接或者间接控制的。EG.控制机器人的程序出现问题，“千年虫”
B.机器人出错与否和产量增加没有必然联系。产量的提升是由诸多因素构成的。

论据3:机器人的大量使用必然代替了工人的劳动岗位，致使工人焦虑，大量的事业肯定不会让工人们有很高的精神状态。

对于论据1。2。3。而言：只提机器人的优点而对其缺点闭口不谈 一面之词

结论: 机器人在外层空间里的成功并不能说明它能在实际的工厂生产中起到它相应的作用。
