一、活动目的

圣诞节是基督教徒纪念耶稣的诞生的节日，是一个西方的节日，但是近年来，它却为越来越多的中国人所接受，并且渐渐被赋予了许多中国式的特色和内容。为了丰富同学们的课余生活，了解和体验圣诞节的气氛，结交新朋友促进沟通，增进彼此的感情，故策划了此次活动。

二、活动主题：圣诞节之夜

三、活动内容

1、时间：2014.12.25

2、对象：110班全体同学

3、活动步骤

A、19：00之前的等待时间，播放圣诞节歌曲，营造圣诞节气氛。如《叮叮当，叮叮当》《平安夜》，活动要求每位参与者携带一张平安夜贺卡，在入场时交给负责人员。B、19:00准时开始。

C、19:00-19:10首先由主持人致辞。内容为圣诞祝福，圣诞由来，以及世界各地的圣诞风俗。D、19:10-19-30，进行第一个活动“拍七令”，目的是为了炒活现场的气氛，让所有人参与到其中来。

活动规则如下：多人参加，从1-99报数，但有人数到“7”的数字或“7”的倍数时，不许报数。在所有到场者中循环2-5次，如果有人报错或拍错人给予一定的处罚。

处罚方式：每循环一次，所以有出错者一起出一个表演，可一起合作，也可选派代表。E：第二个活动，“椅上功夫”。先不宣布活动内容，邀请多名到场者参与，并把参与者按人数分为多组，然后进行比赛，若比赛中人数不够，可再邀请人加入。方法：

1、各组互相商量要如何才能站上最多的人。

2、依照号令比赛，哪一张椅子上站最多的人。

3、可以限定一个时间，如3分钟。惩罚方式：对于人数最多并且站到椅子上人给予一份小礼物，对于人数最少的一组且站到椅子上的人，则给予相应惩罚。

四：奖品设置：笔记本10元/本x10本=100元或杯子15元/个x10=150元
