Please make good use of your life
Dear leaders teachers and schoolmates.Good morning!
Today,my topic is“take care of your life,please.”
A great person have said:Either you make good use of your life,or your life makes use of you.a good heart is significant,it depends on who is hourse,who is hero.New term begins,you I and everyone else starts a new.This time is different from before.Maybe you haven’t found how hard it is,but there are more and more difficulties.Junior three is here.
Maybe we had successed yesterday,but that has been a good memery.Maybe we were in trouble,but that is the past.Forget it.
Dear schoolmates,study is hard,but don’t complain about the expection who cares of you.We need teaching.The most important thing is wherever we are,we should go ahead.We should dare to show our disadvangtages,make good use of our life.An Amerian president got the bad illness when he was a baby,nobody could understand his words,but he didn’t give up his dream.His activities made him win.
Perfect depends on drops.Education depends on drops.Life also depends on drops.Perfect,education,life will make up the most fascinating song.
As Xingling students we should treasure everyday to study.Let’s make good use of our life.Let’s fight for our bright future!
That’s all.Thank you!
