自救是人的天性，很多人在遇到危险时都会有自救的意识，我也有过这样的经历。
有一次，爸爸带着我一起去海边游泳。来到海边，我遇到了我的朋友，一位小哥哥，我们俩吃了点东西就匆匆下海游泳去了。
小哥哥提议来场比赛，看看谁游得快游得远，我连声叫好，爽快地答应了。一开始，我飞快地向前游去，眼看着把小哥哥甩在了后面。心里正暗暗得意，我的右腿却突然抽筋不能动了。我在原地划水，小哥哥趁机游了过来，嘲笑道：“呦，怎么游不动了？我先走一步了。”
眼睁睁看着他要游走了，而我一条腿根本不能动，只好求救：“小哥哥，帮我一把，我快不行了。”他以为我在开玩笑，游得更远了。我的力气渐渐耗尽，感觉马上就要沉下去了，这时我急中生智，屏住呼吸，浮在了水面上。直到小哥哥回来，他才发现我真的坚持不住了，奋力把我拉回岸边。
虽然这场游泳比赛我输了，但是我学会了在海上自救的方法。当然，从那以后，我再也不敢向海的深处游了。同时，我也懂得了：遇到危险的时候千万不要慌张，要有战胜困难的勇气和信心，努力想办法使自己摆脱困境。

在雷雨季节里，常会出现强烈的光和声，这就是人们常见的雷电。带有电荷的雷云与地面的突起物接近时，它们之间就发生激烈的`放电。由于雷云电压高电量多，并且放电时间很短，放电电流大，因而雷击电能很大。虽然放电作用时间短，但对建筑群中高耸的建筑物及尖形物、空旷区内的建筑以及特别潮湿的建筑物、屋顶内金属结构的建筑物及露天放置的金属设备等有很大威胁，可能引起倒塌、起火等危险事故。
俗话说：水火无情，地震无情。只要我们把安全牢记在心。那我们的生活就会变得多姿多彩。

每个人都会有独自在家而感到害怕的时候，你又是怎样解决的呢？
有一次，我一个在家写作业。这时，突然门铃响了起来，我的神经一下子绷紧了起来，我拿起家里打蚊子用的电蚊拍轻手轻脚地向门口走去，我踮起脚尖趴在门镜上向外看。只见门外站着两个个子差不多高的陌生人，穿着蓝色的工作服，在他们中间还放着个大箱子。我想难道他们是来抢劫的？我刚想问找谁，就想起爸爸的叮嘱：一个人在家，不管谁敲门都不要开门，也不要理会。万一外面来的是坏人，知道家里只有一个小孩子闯进来怎么办。于是，我又蹑手蹑脚地走回了房间，任凭他们怎么敲门，我都不理会。
过了一会儿，我又听见了钥匙开门和爸爸的声音，我心里的石头终于落地了。原来是虚惊一场，门外的那两个人是来给我们家送新电视的。
电视安装完了，送走了两位安装工人，爸爸对我说：“今天表现不错，没有因为好奇心而开门，要是外面是坏人，你既保护了自己，又保护了全家。”
我想，每个孩子都应该有自我保护的意识。不让自己受到伤害。
