题目：
Your university plans to open a café inside the campus library. Do you think this is a good idea? Explain why or why not.(TPO34)
范文：
Well, if you ask me whether it is a good idea to open a café inside the campus library, I would like to say definitely yes. I have two reasons to name.
First, it’s a good place for us to take a break and get refreshment. We go to the library to do research or study for finals, which are quite intense and complex work. ① Sometimes my head gets a little dizzy from staring at the books for too long. In that case I would like to get a cup of coffee and clear my mind for a while.
What’s more, it’ll also be more convenient for us to grab something to eat.
② I mean, sometimes when we are in a hurry, we go to the library without having breakfast, especially during the final week. ③ So it’ll be fantastic if we can order a muffin and a cup of Capo-chino inside the library.
论证方法分析：
其中①为举例论证方法，②为解释论证方法。
③处出现了表示结果的标志词so，作者说如果我们能够在图书馆内享用a muffin(玛芬蛋糕) and a cup of Capo-chino (卡布基诺)，那么这将是令人非常愉悦分事情, 属于因果论证，这是对分论点it’ll also be more convenient for us to grab something to eat. 的展开论证。
