1. Some students interpret the postscript of the paper as a thank-you letter, and the whole article is a thank-you letter, which loses its original meaning; It is unreasonable to write too lyrical, which leads to the whole postscript becoming lyric poetry, even in the form of poetry; The content of thanks is not properly written, which will make the thanked person feel embarrassed. Therefore, when we write the postscript, we should praise it moderately and appropriately.
2. Some students always like to pull the tiger skin and pull the banner when writing their graduation thesis, which will attract the support of many academic experts. Others like to tell what they have seen and heard during their travels, and forcibly connect them in the postscript. What's more, I can't understand the overall structure of the article, such as postscript, beginning, thanks and so on. They like to suddenly become lyrical "Time flies, time flies" in the last two paragraphs.
As a positive postscript, don't make some low-level mistakes to make people laugh, and don't be too serious and casual. The content of the postscript should not be too short, otherwise you can't explain clearly what you want to express; Not too long, too long will make people feel embarrassed, and it is best to condense it into a meaningful sentence.
The conclusion, as the end of the paper, expresses some unfinished feelings in implicit language, which will arouse readers' thinking and singing, rather than moaning without illness, and appropriately express their true feelings. Finally, remind the students to check the paper again after writing it, and don't let your efforts be in vain!
