大家都吃过奥利奥的饼干吧，是不是特别的好吃？我就特别爱吃：）
其实奥利奥的英文名称OREO，也同样适用于书写议论文的基本步骤哦！是不是很不可思议，让我们一起来看一看吧：）
如： I (strongly/honestly) believe that ......
第二步：阐述理由（reason）
The reasons are as follows:
1, ......
2, ......
3, ......
或者One thing is ......, and another thing is ......
第三步：举例说明（example）
举例说明时，最好跟第二步阐述的理由是对应的。可以用到的句子有：
A friend of mine says ......
How would you feel if ......
If these plans go ahead ......
If you continue to think this way ......
第四步：重申观点（opinion）
Therefore, my opinion is ......
为了让大家更加清晰了解这个OREO原则怎么使用，我特意给大家找了一篇persuasive letter（比如投诉信，也是议论文的一种形式）来给大家做范例。
请先看一下写persuasive letter的步骤：
1，书写日期
2，称呼对方
3，积极的开场（给人留下好印象，以便把信读完）
4，阐述遇到的问题（此时可以运用OREO原则）
5，建议的计划和方案
6，积极的收尾
详细例子请见：
October 31, 2016 ---书写日期
Dear Crispy Bite Potato Chip Company, ---称呼对方
Thank you for continuing to produce delicious potato chips. Whenever I am hungry for a snack, I always choose Crispy Bite Potato chips. The barbecue flavor is my favorite. ---积极的开场
However, I feel that your small snack-size bags do not contain enough chips. ---表达自己的观点（O)
I am always very excited to open a new bag and then disappointed when I find that it is barely half full. I don't feel like I am getting my money's worth. Could you fill the bags a little more or make the size of the package smaller?
Maybe a smaller package could enable you to lower the price. ---阐明理由并举例，同时还给了建议的计划和方案。(RE)
Your company has always produced a high-quality product that all of my friends and I enjoy. I thought you would want to know about our problem with the amount of chips in your bags because I am sure you are interested in your customers' opinions.---重申自己的观点(O)
Thanks for your attention and your delicious chips.---积极地收尾
Sincerely,
Allen
这样是不是更加清楚了呢？希望对大家有帮助：）
