The tendency of writers who paraphrase is to keep certain keywords in the same position within a paragraph intact.
Only bad writers (and students) exhibit that tendency. While I always prefer to write all of my projects from scratch, I don't
refuse to rewrite a project if the client insists on that instead of a brand new paper. On those occasions, I don't retain
any of the original wording at all, let alone in its original place within any sentence or paragraph. My vocabulary, grammar, and sentence structure will always be much better than the writing in the original paper, so in addition to just being entirely
different -- and, therefore, unidentifiable as the original paper -- the new paper that I provide is also, invariably, written much better than the original. Once the citations and references are changed to appropriate alternate citations and references, it is completely unrecognizable, whether to software or to any human eye. To a reader, the new paper is nothing more than a totally different project on the same topic as the original and not any more connected to the original than projects authored by different students on the same topic in different semesters, which occurs routinely, especially at the undergraduate level.
