有照为证时间随着爬在墙上的暖阳一寸一寸地走过,快下班了,我整理好桌上的一切,坐等着下课铃的响起。无聊之际,我随手翻起邻桌的几本作文本,竟看到了这几个片断——(见图1、图2、图3)想想,我班的小家伙似乎也犯过类似的错误。这“精密”“周密”和“严密”中都含有“密”字,而且彼此的意思很相近。因此在平时的学习、使用过程中,很多同学难以准确地区分它们。其实,只要我们真正走近它们,深入地了解它们,就会发现这三个词语之间还是有一定区别的! As the evidence for the time climbed with the warm sun on the wall inch by inch walked fast work, I finished everything on the table, waiting for the bell rang.

This “precision ” “close ” and “tight ” contains “secret ” word, and each other’s meaning is very similar. Therefore, in the usual learning and using process, many students find it difficult to distinguish them accurately. In fact, as long as we really approached them, in-depth understanding of them, we will find that there is a certain difference between these three terms!
