Joan: Hi, how are you? What are you doing? What is this?
Roberto: Whoa! You're very high- strung this morning.
Joan: Am I? I am a little wired. I've been up all night trying to finish an assignment for one of my classes.
琼：有吗？我只是有点焦虑 。昨天我一整夜都在赶着完成课堂作业 。
Roberto: You don't seem tired at all for having been up all night. In fact, you seem to be bouncing off the walls.
罗伯托：你看起来一点都不像忙了一整夜的样子 。事实上，你显得无比兴奋 。
Joan: What are trying to imply? Sorry, I didn't mean to snap at you. I've been drinking a lot of coffee and energy drinks. I still have a lot of caffeine in my system.
琼：你在暗示什么？对不起，我不是故意咬你的 。我喝了太多的咖啡和能量饮料 。我身体里仍残留着许多咖啡因 。
Roberto: That's for sure. You seem agitated from too many stimulants.
罗伯托：那是肯定的 。你这么激动，像吃了兴奋剂似的 。
Joan: Well, I needed to stay awake, so as soon as I felt drowsy, I'd have another dose of caffeine. It gave me an instant jolt!
琼：额，我要保持头脑清醒，所以一打瞌睡，我就再摄入一个剂量的咖啡因 。就像安了即时震动似的 。
Roberto: But you're done with your assignment now, right?
Roberto: And you have a few hours before your class, so why don't you get some sleep?
Joan: Sleep? Sleep?! I don't know the meaning of the word!
