——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？

Dear Admission Committee:
Miss Pan Bei requested a letter of recommendation from me to support her application for graduate program at your university. As her teacher, I am pleased to comply with her request.
I first got to know Miss Pan when she enrolled at university and I was the assistant director of her class at that time. Being a professor for several years, I noticed that due to the lack of self-learning ability, it is really challenging for students, even those performing excellent in senior school, to keep up with the college speed. However, as a diligent girl without any solid background in Computer Science before college, she adapted quickly to the especially competitive environment in our department. At the end of the first year, she earned the 5th rank in her class, while ranking 1st among the girls. I was fairly impressed by her self-learning technique and exceptional efforts. Hence, I believe, goal-oriented, not afraid of inchoateness and with persistence, she has the quality to make achievements.
What distinguished her among her classmates, I think, was that she went far beyond acquiring excellent scores in the exams and instead got her range of knowledge enlarged. In spring, 2006, Miss Pan took the course I taught named Algebraic Structures and Combinatorial Mathematics. This inquisitive and assiduous young woman was sometimes the last to leave after my class, raising novel questions related to the subject. I found that she understood the knowledge in depth and detail. Furthermore, I still remember during the spring vocation in May, due to the break-down of my mail box, I missed her mails to discussing some questions. But the following week during the course time, she asked me directly. Her zeal for knowledge and the spirit to explore answers really leave me a deep impression. Finally, she was among the few students who got almost full marks in every test in class which showed her exceeding grasp of every chapter. Thus, I gave her 98/100 for the excellent performance in my course.
In summary, I have every reason to believe that Miss. Pan will make outstanding performance at your university as a graduate. I would appreciate greatly if you give her a favorable consideration. Please feel free to contact me directly if more assistance is needed. Faithfully yours,
Wanling Qu, Professor
Department of Computer Science and technology Peking University

我家养了一雌一雄两只孔雀鱼，那只雄孔雀鱼小巧玲珑，桔红色的尾巴上点辍着蓝黑色小圆斑，像孔雀的尾翎。游动的时候，他的尾巴徐徐飘动，像一位优雅的舞蹈家，在水中翩翩起舞。那只雌孔雀鱼尾巴短身体长，全身银灰色，透明的尾巴上虽然有一些花纹，但比起雄鱼就要逊色得多，它性格内向，像一位高傲的公主。
他们吃鱼食时十分有趣，总是先把身上竖起，张开小嘴向鱼食扑去，将鱼食吐出又吞进去，然后又将食物吐出。就这样反反复复，多好玩啊!吃饱后，他们就在自己的小天地里快活地玩耍，好像一对恩爱的夫妻。妈妈曾经对我说过：“它们不能分开，如果把他们分开他们就会因为孤独而死去。”
有一天晚上，妈妈赶紧把我叫来，只见雌鱼一动不动的躲在水草中，妈妈说“快看快看她在生小宝宝了!”我发现水果中有几条透明的小鱼在轻轻的游来游去。不一会，鱼妈妈又产下了几只小鱼。我仔细观察发现，刚刚产下的'小鱼盘着身体，被透明的薄薄的水泡泡包裹着，接着小鱼舒展开全身，水泡破开，鱼宝宝拼命地游向水底。
“为什么一生下来就是小鱼呢?”我好奇的追问。
原来孔雀鱼属于卵胎生鱼类，大多数鱼在毓时把卵产在水中，让卵发育成鱼，孔雀鱼则先在母体中发育成幼鱼，然后再生下来。
我爱色彩斑斓，婀娜多姿的孔雀鱼，因为他们给我带来了无穷的乐趣。

读书笔记分为摘录笔记、提纲笔记、评注笔记、心得笔记四种。
摘录笔记就是把所读文章的好句子、好材料摘录下来的笔记。这种笔记有的同学小学时就做过，但是坚持下来的人很少。摘录笔记做多了，经常读一读，对于提高我们的语言表达能力很有帮助，在时可以参考、模仿，有的甚至可以直接引用。
提纲笔记就是把所读文章的要点归纳记录下来的笔记。它对于我们阅读分析很有帮助，也有助于我们提高作文的构思能力。
如果所读的书是自己的书，还可以在书的空白处写下自己看法、疑问、评论等，也可以做一些记号。这就是评注笔记。它会加强我们对文章的理解、记忆，作文时如果要参考、模仿渡过的文章，有没有做过评注的，效果大不一样。
心得笔记简单的就是扼要地写一写读书的心得，可以不过多考虑格式，把心得记下来即可。上一讲我们说找文章的“眼睛”，实际就是一种心得，你把它记录下来，不用过多地展开议论，这就是心得笔记。
广义地讲，读后感也是心得笔记之一，但人们一般都把读后感独立地提出来讲解和练习。我们也这样做。
