Weird Butterfly Ceremony

課文：

Sarah and Rachel are roommates at their university.

Sarah：I’m going to stay up late again tonight. I have a big history paper due tomorrow.

Rachel：I have one to finish, too, but I’m tired. I think I’ll go to bed now and get up early to finish it.

Sarah：Well, whatever floats your boat. I’d be exhausted if I got up as early as you do.

Rachel：That’s because you go to bed so late.

Sarah：I like going to bed late. I can concentrate better when there are fewer distractions.

Rachel：I was about to say the same thing about getting up early. Besides, it’s easier for me to make time for things like exercise and planning then, before I get busy.

Sarah：I’ve tried waking up early, but I just don’t have the willpower.

Rachel：If you can make a habit of getting up early, it’s easy. And speaking of willpower, I read that people have more willpower early in the day. Making decisions tires you out, so you make better choices in the morning.

Sarah：Maybe. But I also read an interesting study. It said people who stay up late get a surge of energy later in the day. Early risers don’t.
