Especially those who come down from the internet, use it less. Some teachers will paste and copy directly and search for similar paragraphs.
It is best to write more and copy less in the opening report. In fact, the teacher doesn't have that much time to finish reading your paper, so the opening report is the focus of review.
As for the content of the text, I suggest buying one or two less famous books. Just typing a few more words to copy the whole paragraph will make it difficult for the teacher to catch it.
Moreover, it is best to make some small mistakes in obvious places and let the teacher "play" the place. After all, it is impossible for paper not to be changed. Anyway, the teacher has to give some advice. You find a few places to point out, and you don't pay much attention to the rest.
Come on, everything will be fine after writing the paper!
