评论式笔记不单是摘录，而且要把自己对读物内容的主要观点、材料的看法写出来。其中还可表达出笔记作者的感情。评论式笔记有下列几种：
1．书头批注
书头批注是一种最简易的笔记作法。就是在读书时，把书中重要的地方或自己最深的地方，用笔在字句旁边的空白处打上个符号，或者在空白处加批注。如***在读<伦理学原理>一书时，用朱墨两种色笔在书中作了不少的圈圈点点，遇到他认为观点正确、文字优美的地方，就批上“此论颇精”、“此言甚合我意"，认为不对的地方就画‘‘×”，或批上“不通¨、“荒谬”之类词句。
这种笔记方法只能在自己的书上用，这是应当注意的。
2．评注
评注笔记，是读完读物后对它的得失加以评论，或对疑难之点加以注解。例如顾维桢(捕风提影说思维>中的一段文字：哥德尔的不完整定理。是数学史里的一个里程碑。原来在严谨的.数学堡垒之中，竞有一大漏洞，而且这漏洞是无可填的。本来严谨的数学架构，以少数的公理为基础，以明确的推演为方法，导出七层宝塔似备辉煌威果来，真是美不胜收。而且高妙的数学架构，严谨之外，兼具普及性：貌似不同的事物，透过抽象表达，往往可以归纳在同一种数学描述范围之内，看来真是放诸四海而皆；隹了。哥德尔却证明，凡是普及性高的正式逻辑系统，其中必有某些命题，是无法以这系统的逻辑去辨别其是非的。这毛病多半出在“只缘身在此山中”。

要根据收信人的.身份，写表示祝愿的话，以示礼貌。
一般性的“此致”“敬礼”，格式是另起一行空两格写“此致”，“敬礼”下一行顶格写。 给长者的信往往写“祝您健康长寿”，给朋友写“祝工作顺利”，给晚辈写“祝你学习进步”。
祝
学习更上一层楼。
