I Must Finish My Homework 我一定要完成作业

Every time when the holiday comes, I will be very excited and forget about all the things. I always finish my homework in the last minute, which annoys my parents. So I decide to change this bad habit and finish my homework first. Then I can go out to play with my friends. Only in this way can I be responsible to myself. 
每次假期到来时，我都会非常兴奋，忘记了所有的事情。我总是在最后一刻才完成作业，这一点让我的父母感到烦恼。因此我决定改变我的这个坏习惯。先完成家庭作业，然后再和我朋友出去打球。只有这样我才可以对自己负责。
