When writing a composition, students often quote some other people's words and examples as the basis, or introduce some famous sayings, idioms and allusions to illustrate things. How to use punctuation correctly when quoting? First, whenever the quoted words are used independently, the punctuation at the end is put in quotation marks. Xiaodong said, "You are my bosom friend." This is a character dialogue written by Zhang Wei, a student in my class. In addition to changing the period that Zhang Wei kept outside the quotation marks in the composition book, I also told the students in class: "Punctuation marks are an inseparable part of a sentence, just like the tail of a sentence. Where the sentence moves, it follows. " It's wrong to shut your tail out of the door. "The whole class will laugh. Second, take the quoted words as part of the author's own words, and there is no need to add punctuation at the end of quotation marks. "Young people don't work hard, and the elderly are sad. "This is very reasonable. This is a sentence written by Zhang Wei in a later composition. I put "young people are pathetic." I first affirmed his hard work and good thinking, and then explained to him, "Yes,' Young people don't work hard, but the old people are sad' is a complete sentence, and there should be a full stop.
