It depends, there are people that cut and paste from wikipedia and that makes up 80 percent of their article. A reference is a reference or perhaps a short paragraph, not a page. I am sure that there are work arounds with references but I do not run into these problems myself as I create essentially all content personally. I am not the best person therefore to ask about what constitutes plagiarism and theft.
In my opinion, write a lot, cut and paste very little, if at all.
Thank you very much Sir @tarazkp, your opinion is very helpful for me, sometimes I also thought like that, but I do not know to whom to ask how the solution. Kareana coincidence you give the posting about it so I was immediately asked to you Sir. Maybe in the future I should be more careful in taking the quote. As you say the quote that's just sentence rather than the page. Thank you so much for your response Sir.
