There are generally two ways to mark the page number of references, namely "starting page number-ending page number" and "total page number". Which method you choose depends on the citation method you use or the requirements of academic journals.

1. Starting Page Number-Ending Page Number: This method refers to the specific page number range in the cited documents, and is generally used to quote articles, books, papers and other specific documents. When marking, you can use "pp." or "p." to indicate the page number, such as "pp. 35-40" or "p. 25-30".

2. Total number of pages: This method refers to the total number of pages of cited documents, which is generally used to quote the whole book or periodical. When marking, you can use "vol." or "No."to indicate the volume number or issue number of the journal, and "p." or "pp." to indicate the total number of pages, such as "vol. 25, no.2, pp. 200-220" or "p.100-6544".

It should be noted that when marking the page number of references, it needs to be adjusted and revised according to the actual situation, and follow the academic norms and requirements, correctly list the literature information and indicate the source. At the same time, when using quotation, we should also pay attention to the correctness of quotation format and punctuation, as well as the cohesion and logical relationship between quotation and text.
