When you wake up every day, once again to see this beautiful world, when your parents, teachers and friends give you help, will you know how to be （71）grateful? And when you feel unlucky and make mistakes, will you still be thankful?
Yu Dan, a professor at the Beijing Normal University, made a report about Gratitude Education（感恩教育）．It will affect Chinese people, especially the teenagers．
Nowadays, some teenagers only care about things outside．They often behave badly．For example, they fight each other, use phones in class, be rude to their parents and teachers and so on．Most of them don’t know love, respect and gratefulness．
Being grateful or thankful is very important．（73） It is impossible for anyone to be lucky and successful all the time as long as he lives in the world．We should learn how to face failure or bad luck bravely and to try to deal with it．As we know, “Life is a mirror．When you smile in front of it, it will also smile and so will it when you cry to it．” If you are grateful to life, it will bring you shining sunlight．If you always complain about everything, you may own nothing in the end．
I think the teenagers should be grateful to life even when we are unsuccessful or unlucky．We have many reasons for being grateful．For example, being grateful is a way to communicate with adults．And it is a way to sing for our life which comes just from our love and hope．
If each of us has an attitude of being grateful, we’ll lead a better and more beautiful life．So remember, being grateful forever．
