If the quotation comes from multiple volumes, the author's surname and page number should be indicated in addition to the volume number. 1 in brackets is the volume number, and lowercase Roman numeral I is the page number, indicating that the quotation comes from the preface of volume 1. If two or more articles by the same author are cited in an English paper, the author and page number of the original text should be indicated, and the name of the cited work should also be indicated, which is generally expressed by numbers.
Some teachers will assign some homework to appreciate English poems, and this kind of paper will definitely quote the original poems, so these quoted poems must be separated by slashes, and there must be spaces between slashes and letters and punctuation marks before and after; If you quote more than three lines in your English paper, you should still separate the quoted lines from the original English paper.
