对话
L: Hi Mary, how is your summer holiday?
M: Just so so, go nowhere.
L: How about the homework?
M: half done. I really don't want to do homework in the beginning of the holiday.
L: It is the first step that costs troublesome.
M: Sure, I am really lazy and don't want to do anything except relaxing.
L: Yes, I still trust a good beginning makes a good ending. I make a plan before I start.
M: You are right. Experience teaches. Last year, I almost didn't finish my holiday work.
L: Anyway, better later than never. Only if you want to go, just go.
M: I always think you are a perfect student, our teachers like you. You study hard and take part in many activities in school.
L: Every bean has its black. Like me, I have my black. Such as sometimes I have lazy time and I feel running out of energy. I am short of management capability and so on.
M: But it doesn't affect your school.
L: Well, we should know how to adjust and control ourselves. Enough is better than too much.
M: I got it. You study hard and you win.
L: Hahaha… Exactly. As a man sows, so he shall reap.
M: It's sink or swim.
L: Yep. So let’s study hard together and we will make it.
M: Go. I couldn’t wait to finish my holiday work now!
L: Let’s do it together.
