【点评范文】
1. 内容：文章内容全面，作者介绍了新发明的名称、发明时间、用途、构造、工作原理及价格。由于此文的写作目的是推销一项新发明，若在文章开头点明该发明适合的目标群体、潜在用户会更有利于销售(将you改为 those who need to look for their glasses from time to time)。
2. 语言：在介绍该发明的工作原理时，作者使用了表示顺序的词first和then，使得听众容易明白如何操作。如果将文章的最后一句话If you hate it, please come to me and buy one改为If so, please come to me and buy one，文章的语言会显得地道而精练。
