    4月份国旗下讲话:牢固树立生命安全意识

    老师们、同学们!今天我讲话的题目是:牢固树立生命安全意识。百善文明为先,万思安全是重。确保学生的安全健康,不仅关系到每个家庭的生活幸福,更关系到整个社会的稳定与祥和,保护学生安全,是学校、家庭和社会的共同责任。1996年国家教委、劳动部、公安部、交通部、铁道部、国家体委、卫生部联合发出通知,决定每年3月份的最后一周的星期一为全国中小学生安全教育日,每年确定一个主题。XX年3月30日是全国中小学生第十四个安全教育日,主题是“加强防灾减灾,创建和谐校园”。11年汶川地震的灾难让我们再次明白,生命的脆弱竟有如一只芦苇,稍不注意,它便会从你手中悄悄溜走。一位老师曾经对我讲述过这样一则交通安全事故:那是一个晴朗的日子,一个男孩骑着自行车,由于他骑得太快了,差一点儿就撞上了斑马路上的行人。行人劝他不要骑得那么快,可他毫不在意,继续骑他的“飞车”,在一个拐弯的地方,“飞车”男孩,倒在血泊中……其实我们要树立的生命安全意识并非只有交通安全,它还包括很多方面,如课间活动的安全、食品安全、交友安全、网络安全,等等。专家指出,通过安全教育,提高中小学生的自我保护能力,80%的意外伤害将可以避免。可见,关爱生命,创建和谐校园,最重要的是树立安全意识,加强安全防范。

    3、重要语句的理解“可是一个人并不是生来要给打败的,你尽可把它消灭掉,可就是打不败他。”解析:这是老人第一次回合之后的内心独白,也是此小说的核心精神,充分体现了老人桑地亚哥的生命理念。整句话可以分为两部分来理解,前句告诉我们,人生活在自然与社会当中,必不可少要面临一些坎坷、磨难,这些磨难、坎坷完全可以造成躯体的消灭、消亡,这是人生命的脆弱性。后句,面对挫折,只要保持一种乐观的精神,拥有一颗坚强的心灵,那么,人类执着奋斗的精神将永不磨灭。4、象征主义题目是《老人与海》,而表明上,小说是写一位老人及其在海上的经历,但实际上,老人的形象极具概括性,他已经超越了一个人的存在,而成为了人生的一种象征。老人桑地亚哥就是“硬汉子”的代表,大海则是生命旅途的象征,鲨鱼则是我们行走中的“强物”,厄运的象征。人的一生不可能一帆风顺,不经历风雨,怎能见彩虹,走在人生路途中,不可避免我们都要遇到挫折,被厄运所阻挠,只有经历与“鲨鱼”的较量,才能成为强者,唱出最美的歌。
