Not necessarily. Only those that must appear in your argument need to be quoted. ? References generally have two purposes, one is to learn from the methods it uses, and the other is to support opinions. If you only use the methods used in other people's papers for reference, or give some enlightening information, you don't need to quote them. Of course, if the paper needs to explain the method, then quote it. And if the literature is used to support your point of view (the literature in the current research situation is also used to support your point of view and prove that your research has not been studied), it must be added to the paper.

Format of references in papers I. Types of references

The type of reference (i.e. citation) is identified by a single letter, as follows:

M monograph c paper n newspaper article

Journal paper D paper R report

For files that do not belong to the above types, use the letter "z" to identify them.

For English references, we should also pay attention to the following two points:

① The author's name adopts the principle of "surname comes first, surname comes last", and the specific format is: surname, initials of first name, such as Malcolm.

Richard Cowley should be: Cowley, M.R., if there are two authors, the way of the first author remains the same,&; After that, the first letter of the second author's first name is put in front, and the last name is put behind. For example, Frank Norris and Owen Gordon should be: Norris, F.&;

L. Gordon;

(2) Titles of books and newspapers are in italics, such as Mastering English Literature and English Weekly.
