大家都吃過奧利奧的餅干吧，是不是特別的好吃？我就特別愛吃：）
其實奧利奧的英文名稱OREO，也同樣適用于書寫議論文的基本步驟哦！是不是很不可思議，讓我們一起來看一看吧：）
如： I (strongly/honestly) believe that ......
第二步：闡述理由（reason）
The reasons are as follows:
1, ......
2, ......
3, ......
或者One thing is ......, and another thing is ......
第三步：舉例說明（example）
舉例說明時，最好跟第二步闡述的理由是對應的。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：重申觀點（opinion）
Therefore, my opinion is ......
為了讓大家更加清晰了解這個OREO原則怎么使用，我特意給大家找了一篇persuasive letter（比如投訴信，也是議論文的一種形式）來給大家做范例。
請先看一下寫persuasive letter的步驟：
1，書寫日期
2，稱呼對方
3，積極的開場（給人留下好印象，以便把信讀完）
4，闡述遇到的問題（此時可以運用OREO原則）
5，建議的計劃和方案
6，積極的收尾
詳細例子請見：
October 31, 2016 ---書寫日期
Dear Crispy Bite Potato Chip Company, ---稱呼對方
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. ---積極的開場
However, I feel that your small snack-size bags do not contain enough chips. ---表達自己的觀點（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. ---闡明理由并舉例，同時還給了建議的計劃和方案。(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.---重申自己的觀點(O)
Thanks for your attention and your delicious chips.---積極地收尾
Sincerely,
Allen
這樣是不是更加清楚了呢？希望對大家有幫助：）
