Well, to be honest, working overtime is the last thing that I would like to do in the world. Can you believe sometimes we have to work around the clock without any break? No bragging. Seriously!
注释：
working overtime 加班
Work around the clock 工作12小时
without any break 没有任何的休息
No bragging. Seriously! 不夸张，讲真！
Um, You know we usually study against the clock before the final exam. It’s a harsh time but we have to admit that we do learn a lot, especially in a short time. It feels like that our brains work better.

our brains work better 我们的大脑运转的地更好了
