如何保护粮食安全英语作文500词【五】
随着暑假的到来，越来越多的学生都选择了游泳，来作为自己暑假里的娱乐方式，这本是非常好的，可是，却有很多人，没有到正规的地方游泳，甚至去池塘，河流等危险的地方游泳。
目前全国每年有1。6万名中学生非正常死亡，溺水和交通事故死亡居前两名。
江河湖泊往往装出一副平静、温柔的样子，让人忽视了温柔的背后是多深的地狱。有多少人落入了这无底的漩涡、这可怕的魔爪。
身边，也许这些沉重的画面时常可见，就在我们身边，悲剧正在上演着。
当你看见朋友要私自去河里游泳时，你会阻拦吗?
当你看见有人在水中挣扎时，你会张皇失措吗?
当你在没有家长陪同，有炎热难耐时，你还会任性的往水中跳吗?
一些学生因为逞强好胜，不知水深，潜入水中，还做出各种各样的姿势，导致体力不支。碰到这种情况的学生，有的被救了，但另外的学生呢，则再也无法重新开始了。这难道是天意吗?难道活下来只能靠运气吗?
离去的学生或许很后悔，但再也来不及改正了，只留下在世的亲人悲痛不已;死里逃生的学生，带着侥幸心理，但恐怕再也不会有第二次了吧;对于那些从没有遇到过这件事的人，趁来得及，更加珍惜自己的生命。
溺水时可以避免的，只是学生缺乏“游泳安全”的意识以及防溺水知识。
身边的河流只便于用来欣赏，享受游泳的乐趣还是留给那些有和准备的人吧，他们总是预料到一些可能发生的事情，准备好应对的方法。
在不知水深的情况下，绝对不可以以身试险;在有障碍物或有漩涡的激流中，也不可以轻易下水。游泳之前一定要做好安全措施，如救生圈，必须要有懂水性的家长陪同，还要做一些准备活动，否则有可能会导致头晕、恶心、心慌等不适应的现象。若在水中大腿抽筋，应立即上岸，在无人时，也要学会自救的\'方法：先吸一口气，仰浮在水上，用抽筋肢体对侧的手握住抽筋肢体的脚趾，并用力向身体方向拉，同时用同侧的手掌，压在抽筋肢体的膝盖上，帮助抽筋的腿伸直。
生活中世事难料，我们要好好把握自己的生命，对自己的生命负责，不能因为一时大意而让自己身处险境。看着身边一个个生命就这样在世界上消失，请记住这一个个教训。
预防溺水，珍爱生命，希望我们每个人都能够重视这些问题，不要为了一时的快乐，而让自己的生命陷入危险之中。
