dear teachers and students,

    this title remends me of something,however,these things are likely  tiny.you can see a little girl who is washing bowls with her mother,then her mother says to heryou are really my good daughter!we all think that little girl must be happy to do something when other people who need help.we can say a world that changes the world.in fact ,we need each other! if you want win the competition,the encourage of teammates is very important for us,so we gain the victory in the last! then i will give different example to you.we all know chairman mao who is a great man.we must remeber his wordchinese is up from now on!when he stand in the tain an men square!we can say a word that changes the world.no matter how small or great the things are,sometime ,a word that changes the world when we   know it or not.翻译：这个标题，让我想起了一些事情，尽管这些事情看起来有些微小。我们看到一个小女孩正在认真和她的妈妈洗碗，她的妈妈对她说，你真是我的好女儿，那我们都会认为那个小女孩也会很开心帮助那些需要帮助的人。我们可以说，一句话改变了一个世界。事实上，我们彼此需要。如果你想赢得一场比赛，队友的鼓励对我们来说很重要，所以最后我们会赢得胜利。我将给大家举另外一个不同的例子，我们都知道毛主席，一定记得他站在天安门广场上的一句中国人民站起来了，我们可以说，一句话改变了世界。不管事情是大或小，有时候在我们不知道或知道的时候，一句话改变了世界。希望能帮到你，可以保存之后，再完善下！个人的见解！
