心涛：早上好，洋洋!昨晚睡得好吗?今天早上路上没堵车吧?吃早饭了吗?

洋洋：早上好，心涛!奇怪!你每天早上都睡眼惺忪的，怎么今天一反常态，这么精神呀。连珠炮似的问我这么多问题。

心涛：嘿，为了早点写完老师布置的论文，我一宿没睡觉。

洋洋：这么努力啊，可你看上去一点也不像一宿没睡的，你看你，面色红润，气色很好呢!

心涛：这个嘛，我有秘密武器啊。我从昨晚开始就不停的喝咖啡和各种提神的饮料，估计现在身体里还有好多咖啡因呢，不精神才怪。

洋洋：原来是这样啊。那你论文写完了吗?

心涛：嗯，来学校前刚刚完成。

洋洋：现在离上课还有一个小时呢，你要不先睡一会儿?

心涛：睡觉?!你开什么玩笑，我现在这么亢奋，怎么可能睡得着?

X: Good morning, Yangyang. How was your sleep last night? Was there a traffic jam this morning? Have you had your breakfast?

Y: Morning, Xintao. That’s so weird. You look sleepy every morning in the past. But today you behave uncharacteristically. Why are you so energetic that ask me so many questions without a stop?

X: I stayed up all night to finish the paper work assigned by the teacher more early.

Y: Great. But you don’t look like someone who stayed up all night. Look at you, you are in the pink.

X: Well, I got a secret weapon. I kept drinking coffee and other kinds of refresh drinks from last night. My body may still contain a lot of caffeine by now. I am energetic for a reason.

Y: Oh, I see. Have you finished your paper?

X: Yeah, I finished it just a moment before I came to school.

Y: It is one hour from now to class time. Would you like to take a nap?

X: Take a nap? Are you kidding me? With so much caffeine, I am too excited to fall asleep.
