Finally,I would like to remind you that there are about two kinds of references,one is APA format and the other is Harvard format.The specific reference format has different regulations according to different schools.In general,students can find their own writing methods in the library,which are not very different.Reference is generally divided into two types:one is to directly reference quotation;One is the indirect reference citing.The direct reference needs to write the specific number of pages in the in text reference,but the indirect reference does not have to write the number of pages.Many students often ask why there are no pages in the in text reference,which means that the reference is an indirect reference,which expresses and summarizes the quoted theory in their own words.As for the number of references,generally speaking,a 1000 word paper needs 5-6 references,a 1500 word paper needs 8-10 references,and a 2000-3000 word paper needs 10-15 references.The more words,the more references.However,it should be noted that in general,the quotation part can only account for 25%-30%of the content of the whole article.However,trunitin is an anti plagiarism software commonly used by universities in Australia.The similarity allowed by a paper is less than 10%,so the part directly quoted can only account for less than 10%of the content of the whole article.
