生活急救知识作文【一】
俗话说：“小震不用跑，大震跑不了。”地震发生时，最重要的是要有清醒的头脑，镇定自若的态度。只有镇定，才有可能运用平时学到的防震小知识。有些人对防震小知识还不够了解，所以我今天专收集了一些防震小知识。
如果你在家里遇上地震，一定要躲到易于形成三角空间的地方，如坚固家具下，厨房厕所等开间小的地方。躲藏的时候，身体应采取相应的姿势：伏靠待定，蹲下或坐下，尽量卷缩身体，降低身体重心。手要抓住桌腿等牢固的物体，保护头部、眼睛、掩住口鼻。
如果你在户外遇上地震，应该蹲下或趴下，以免摔倒，注意不要乱跑，避开人多的地方，不要随便跑回室内。避开高大的建筑物或构筑物，特别是有玻璃幕墙的建筑，避开高耸的物体，如电线杆、广告牌等，跑向空阔的地方。
每次地震时，都有层出不穷的次生灾害并发，因此每个人都应根据不同情况，审时度势，采取灵活的应急对策。

一次，福特公司的大型电机发生了故障，工程师们会诊三个月都没能找出问题的症结所在，只得请来权威斯坦因梅茨，这位权威及时挽救了电机，而有人却嫉妒地说他向公司要一万元简直就是勒索。这一万美元究竟是不是勒索呢？斯坦因梅茨写在付款单上的说明便是最好的回答：“画一条线——1美元；知道在什么地方画线——9999美元。多么有力的回击！画一条线几乎是每个人都会的，然而并不是每个人都知道应该画在什么地方的，这正显示了知识的价值。而且，你看到的仅仅是那一万元吗？斯坦因梅茨挽救了一台电机，让这台电机继续顺利工作，那他便间接创造了几百个、几千个的一万元。这才是知识的真正价值。
高尔基说过：知识是我们这个社会的绝对价值。特别是在21世纪的'今天，各国的经济类型正从劳动密集型过渡到技术密集型，社会求之若渴的不再是单纯的体力劳动者，而是智力劳动者。知识型经济正在以绝对的优势创造着社会的价值。物竟天择，适者生存。面对着数以万计的失业大军，我亲爱的朋友，每天面对着单调而枯燥的课本的你，是否已经找到一个坚持下去的理由呢？富兰克林说过：如果一个将钱倒进他的脑袋里，就没人把他偷走，知识的投资有着丰厚的利润。
朋友，也许你正承受着生活的煎熬，面对茫茫前路，我只有一句赠言：知识改变命运。说了这么多，也许您会觉得我过于浅薄，但是请接受我最美好的祝愿——如果有一天，我们祖国，这台大机器出问题的时候，但愿你会是那位权威，你会是另一个斯坦因梅茨。
