1.儿童节的简介
国际儿童节（又称儿童节，International Children’s Day）定于每年的6月1日。为了悼念1942年6月10日的利迪策惨案和全世界所有在战争中死难的儿童，反对虐杀和毒害儿童，以及保障儿童权利。
1949年11月，国际民主妇女联合会在莫斯科举行理事会议，中国和其他国家的代表愤怒地揭露了帝国主义分子和各国反动派残杀、毒害儿童的罪行。会议决定以每年的6月1日为国际儿童节。它是为了保障世界各国儿童的生存权、保健权和受教育权，抚养权，为了改善儿童的生活，为了反对虐杀儿童和毒害儿童而设立的节日。世界上许多国家都将6月1日定为儿童的节日。
2.中国庆祝儿童节的方式
首先，组织各种各样的儿童活动是庆祝儿童节的主要形式之一。在学校和社区中，会有文艺表演、游戏和亲子活动等多种活动，以满足孩子们对于庆祝儿童节的期待。比如，在学校里，老师们通常会向孩子们介绍儿童节的由来和意义，并且会根据孩子们的兴趣爱好，设计一些有趣的课堂活动，例如：绘画、手工制作、唱歌跳舞等等。
其次，在儿童节这一天，许多家长也会给自己的孩子买礼物或者带他们去游乐场等地方玩耍，让孩子们感受到对他们的关爱与呵护。在中国，很多商家会在儿童节期间推出特别促销，销售各种有趣的玩具、游戏和书籍，为孩子们创造一个美好而难忘的节日体验。
此外，在中国儿童节期间，还有许多机构会给孩子们发放礼物和奖励，以表彰他们在学习和生活中所取得的进步。例如：在一些社区或者公共场合，会设立“最可爱的儿童”评选，选出表现优异的孩子，并且颁发证书和奖状等荣誉证明。这种形式不仅鼓励了孩子们做出更加积极向上的努力，同时也让孩子们感受到来自家庭和社会的温暖与关爱。
最后，为了庆祝儿童节，许多家长会为孩子们准备特别的餐点和甜品。这些美食通常是孩子们喜欢吃的，如巧克力蛋糕、水果沙拉、薯片等，让孩子们在这一天可以吃到自己喜欢的食品，增加庆祝儿童节的乐趣。
总之，中国庆祝儿童节的方式是多种多样的，无论是在家庭、学校还是社区，都会有不同形式的庆祝活动。这些活动不仅可以让孩子们度过一个快乐的节日，同时也向他们传递了积极向上、健康快乐的生活态度，为他们未来的成长打下坚实的基础。

要在文件所在位置创建一个名为img的文件夹
在文件夹中放入一下内容：
1.命名为moon
2.命名为city
