在阅读时，我先要选择一本适合自己的书，不然就会发生太幼稚看不下去或太深奥看不明白的可能。读书时最好顺手准备两支笔，一支黑笔和一支水彩笔。水彩笔用来画好词好句，黑笔则用来做适当的批注。一定要注意，不能为了批注而批注，请铭记，你批注的地方是你真心觉得好的地方，不然画了就没有意义。在阅读时，你难免会遇到一两个生字词。这时，请千万不要草草了事，而是要耐心查字典，不然，下次看了还不认识；如果你有足够时间的话，那就把生字词记在本子上吧！

如果遇到一本好书，那请你反复读几遍，上次看不懂的段落，没准儿这一次你就看懂了。

阅读不等于完整的读书。假如，读书这个整体为百分之百时，此时的阅读也只能占百分之三十五左右，而剩下的百分之六十五，是学以致用，写、填阅读题，甚至课外拓展，都含有你平时阅读积累的知识点。这时，你的百分之六十五就派上用场了，它会给你画上圆满的百分之百。此时，你一本书的阅读任务就完成了。这种心态是要持之以恒的。

同学们，阅读不是件简单的事儿，正所谓“事半功倍”，当你掌握阅读的技巧时，你也能从中体验无限的乐趣，加油吧！

书籍是人类进步的阶梯，这句话是高尔基说的，同时也是我的座右铭。他一直激励着我奋斗，无论是学习上，还是生活上，书一直在无私地帮助我。学习上遇到困难，我懂得在书中寻找答案。因为在平时看得书多，大人们平常出题来考我的时候，我也懂得用书中的的知识进行修改来进行回答，书在我的生活中是不可缺少的一部分，是我的良师益友。

最初，记得我认识书的时候还很小，那时候的我还不知道书对于我们是很重要的。我因为一件事而爱上了读书。有一次，我无意中看了几页书。而刚好有一位同乡人来到我家，问了我几个问题，我便想起了刚才几页书中有答案，便回答出来了。那个同乡人拍手叫好，此刻我心里乐滋滋的，想到原来可以从书中可以从书中得到这么多知识，以后得多看一些书。

就这样我爱上了读书，但那时候的我还有一个缺点：囫囵吞枣的读。因为我那时候不知道应该怎样去读。上了三年级，我在电脑上浏览时，看到有一个网页上看到从书中获得的知识占人体总知识的70%，看到这个数字，我想：“书里的知识有那么多，如果我不看不就变成一个傻瓜了？”我下了决心：一定要多读书，要认真的读，甚至还可以做笔记。

莎士比亚曾今说过：“生活里没有书籍，就好像没有阳光；智慧力没有书籍，就好像鸟儿没有翅膀。”书，一个多么神奇的东西呀！它能让一个人发生巨大变化，从懵懂中无知到充满智慧。热爱读书吧，这是知识的源泉。
