First, the difference in meaning between the two "complete reference" and "incomplete reference" belong to direct reference, but their reference contents are different, which are divided into complete reference and incomplete reference.
The so-called complete quotation means that the quoted content has a complete meaning, at least a single sentence, a complex sentence or even a paragraph that expresses a complete meaning. In a word, the quoted content must express the complete meaning. For example, a famous person once said, "Reading makes people progress." Here is a famous saying, "Reading makes people progress", which is a complete sentence and expresses a complete meaning. So the quotation sheet here belongs to "complete quotation".
The so-called incomplete quotation means that the quoted content is not a complete sentence, and the meaning expressed is only a part of others' content. For example, Mr. Lu Xun called Sima Qian's Historical Records "a masterpiece of historians, and Li Sao has no rhyme." Mr. Lu Xun's words quoted here are partial quotations and belong to "incomplete quotations"
Second, the difference between the two in use "complete quotation" needs to quote the complete meaning of other people's words in use, which belongs to the quotation method in argumentative writing and is a quotation in descriptive writing, and can play the role of making the finishing point in narrative. For example, in argumentative writing, in order to prove the view that "people should be modest", famous aphorisms can be introduced. It can be quoted as follows: There are many famous sayings about "modesty" in ancient and modern China and abroad. The ancients said, "Being full will hurt, and modesty will benefit." Here, the ancient famous sayings are completely introduced to illustrate the importance of modesty, and compared with "all bets are off", the necessity of modesty is further illustrated. This is the meaning of direct quotation, which can be used as an argument.
"Incomplete reference" only needs to use part of the content, that is, only part of the content is quoted, and other content is omitted. Take "modesty" for example. If you only need to quote "moderate benefit" and omit "full recruitment loss", it is an incomplete citation. For example, the ancients said that "modesty is beneficial", which shows the importance of modesty.
Third, the difference between the two in the use of punctuation marks Generally speaking, the period at the end of a fully quoted sentence is placed in quotation marks; After an incomplete quotation mark, such as a period, put it outside the quotation mark. For example, when we want to discuss the importance of people's experience in writing articles, we can quote Cao Xueqin's famous saying: "Everything is learned when things are clear, and articles are written when people are clear." The quotation here is a complete quotation, which leads to the contents of two poems. So use a colon in front and a period in the back.
However, if you only quote part of the content without a complete reference, you should put the period outside the quotation marks, and do not put the quotation marks in front of it. For example, because the complete content is placed in the middle of the sentence and is not quoted by a colon, after the quotation ends, the period is not placed in quotation marks, but outside quotation marks. For example, Cao Xueqin's famous saying about "the world" said, "Be sensible and learn everything."
All the above are examples of direct quotation, all in quotation marks. If it is an indirect reference, whether it is a complete reference or a partial reference, no quotation marks are used.
