——读《金冠的秘密》有感
前几天，我读了一则故事。其内容是，古希腊的一位科学家叫阿基米徳，他在一次洗澡时发现了水的浮力原理。据此，他解开了金冠的秘密。原理是：拿两只大小都相等的罐子，把金冠和一个与它同样重的金块，分别放入装满水的罐子里。水从罐子溢出时，用两个盘子接着，再把两盘水称一下。若放金冠的罐子溢出的水多，说明金冠不是纯金的。这个故事给我的启示是：处处留心皆学问。
世界上的万事万物，都有它自身存在和运行的规律。这些规律有许多我们并不知道。要认识世界，掌握规律，学到知识，就要去留心观察。如果不留心，知识永远不会自动跑到我们的头脑中来。有一次，我家的窗户上结了冰。爸爸问我是怎么回事。我随口说道：“不就是热胀冷缩嘛！”爸爸告诉我要注意观察。经过一次次的观察思考，我才发现了其中的秘密。原来，暧空气遇到冷玻璃形成了水珠，晚上气温下降就结了冰。
我们许多人都洗过澡，为什么阿基米德洗澡的时候，就知道怎么解开金冠的迷呢？阿基米德并不比我们多长一个脑袋，也不多长一只胳膊。他发现水的浮力，是因为他留心观察，才得出结论。如果不留心，他洗一万次澡也不会知道什么是水的浮力。有的同学可能会说:“书本上学到的知识我们没有留心观察，不也掌握了，你说的处处留心皆学问不全对。”其实，书本上的知识也是前人留心观察的结果。就说我们学的地球引力吧，它就是牛顿留心观察发现的。有一次，牛顿坐在苹果树下看书，一只苹果掉在了他的头上，他想为什么苹果不往上掉呢？他留心了这个问题，才知道了地球的引力。
没有一项发明是睡觉睡出来的。我想：一个人只要勤于观察、 勤于思考、勤于试验，不怕失败，就一定能取得成功。
写这种没有约束的“自由”的读后感，不少人比写的读后感要生动、实在，原因就在于“自由”二字，如果你在考试作文时，也保持这种轻松自由的心态，恐怕写出来的作文要多得不少分。仅从这一点分析，经常写一些“自由”的读后感，是不是可以减少你在考试时的紧张的不正常的心理压力，使作文写得更好呢？
