You kept asking me what  I am going to do during this vacation.
Here it is.
I am going to do part of my homework first.
Because I have the textbooks,
I can finish the upcoming units first.
There are three main merits.
First of all,
it can save time in the next semester.
Second,
I can preview the content.
Third,
I can have something to do during my vacation.

So,
quite a bargain, right?
