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.

　　曾經(jīng)，我在一本書上讀到一個故事，講述了在火車上一位老人，他在窗口弄丟了一只鞋子，令大家感到吃驚的是，他立刻把另外一只鞋子也扔出窗外。人們問他為什么這樣做，他說如果有人撿到他的一只鞋子，是沒有用處的，但是一雙鞋子就有價值。老人家是慷慨的，他對生活有著樂觀的態(tài)度。樂觀的態(tài)度是很重要的，當(dāng)我們遇到困難了，就能克服。如果我們總是覺得沮喪，就不會開心。我們無法改變壞事情，但是可以改變我們的態(tài)度。
