If a traffic accident happens and someone is injured, the following steps can be used to treat the injured.In the first place, we should make sure that the accident scene is safe so that we won’t get hurt. We should ask the injured person if he is OK, and see if he is breathing. What’s more, we should check for cuts and wounds. If he is bleeding badly, it is vital that we should try to stop the bleeding by applying pressure to the injury. This is because if a person loses too much blood, he may die.

    第十二周国旗下讲话稿:友爱,班级和谐的纽带

    友爱,是温暖的火苗,融化了人与人之间的冰冷;友爱,是甘甜的清泉,滋润着人与人之间的心灵;友爱,是和谐的纽带,联系着人与人时间的温情。有了它,班级才能像一个家,一个温暖的家,一个充满爱的家。在我们的班级生活中,其实处处见友爱:当同学摔倒,我们帮忙搀扶,这就是友爱;当同学的成绩在下降时,我们主动帮助,这就是友爱;当同学忘带了文具,我们大方借给他,这也是友爱……不过,在我们校园生活中,也时常有一些不和谐事情的发生。多半都是为了些小矛盾而产生纠纷,大家有时明明知道是谁对谁错,可彼此为了面子都不愿拉下赔礼道歉的脸。有时小小的冲动,会带来不小的麻烦!近年来,校园暴力事件在网上频频出现,这些冲动与暴力给自己与他人都带来了无法挽回的伤痛。这些,都在向我们警示:友爱的可贵。

    第九周国旗下讲话稿:增强安全意识,学会自我保护

    同学们,老师们:大家早上好!今天我国旗下讲话的题目是《增强安全意识,学会自我保护》。同学们,安全无小事,事事须小心。增强安全意识,学会自我保护,是杜绝安全事故发生的最好法宝。然而,我们许多同学思想上、心理上和行为上都忽视了安全工作的重要性。据中国青少年研究中心的全国性大型调查发现,安全事故已经成为14岁以下少年儿童的第一死因,并有逐年增加的趋势;全国每年约有1.6万名中小学生非正常死亡,平均每天有40多人,就是说几乎每天有一个班的学生从我们这个世界“消失”!一个个触目惊心、血泪交织的悲剧叫人扼腕叹息、心有余悸,更对我们敲响了安全的警钟。安全关系着我们的生命与健康,切不可麻痹大意。因此,我们一定要增强安全防范意识,提高自我保护能力。首先,要充分认识安全的重要性,树立高度的安全意识。在对待安全问题的态度上,有一种思想特别要不得!那就是认为提高安全意识,实施安全行为,是胆小怕事;而胆大妄为,敢于冒险是勇敢!这种思想是完全错误的!存在这种思想的人往往好出风头,不听教导,也最容易发生安全事故。比如,在公路上飞车的大多会发生交通事故,手持鞭炮燃放的大多会被炸伤,喜欢追逐打闹的大多会发生碰撞事故,喜欢舞刀弄枪的往往会造成伤害……
