Once, I read a story in a book, it told about an old man was on the train, he lost one of his shoes on the window, to everyone’s surprise, he dropped his another shoe out of window quickly. People asked why he was doing that, he said that if the person picked up one of his shoes, it was useless, but a pair of shoes could be valuable. The old man is so general and he has the positive attitude towards life. The positive attitude is very important, when we meet difficulties, we will get over them. If we feel frustrated all the time, then we will not be happy. We can’t change bad things, but we can change our attitude.

曾经，我在一本书上读到一个故事，讲述了在火车上一位老人，他在窗口弄丢了一只鞋子，令大家感到吃惊的是，他立刻把另外一只鞋子也扔出窗外。人们问他为什么这样做，他说如果有人捡到他的一只鞋子，是没有用处的，但是一双鞋子就有价值。老人家是慷慨的，他对生活有着乐观的态度。乐观的态度是很重要的，当我们遇到困难了，就能克服。如果我们总是觉得沮丧，就不会开心。我们无法改变坏事情，但是可以改变我们的态度。
