假设你参加所在年级的英文写作比赛，请按下面文字中的道理完成一篇短文：

　　A drop of water +two drops +many drops =sea

　　A tree +two trees +many trees = forest

　　One person +two persons +many persons =society

　　范文： The picture shows a simple truth : If too many drops of water are put together ,they will become a sea. Many trees standing together form a forest and many people make up a society . It conveys a message to us : A whole is made up of many small parts that are closely related .Nothing or no one could exist alone .

　　The picture sets us thinking deeply : our society is made up of many people who have different personality and characters . If we want to create a harmonious society ,we must live in harmony with others . On the other hand , since everybody is related to others , we should be responsible for what we say and what we do so that we can develop a pleasant relationship with others , which makes it possible for us to enjoy life to the fullest .
