When quoting, you need to insert quotation marks in the paper and list the relevant information in the reference list. Generally speaking, a 200-word citation can be marked in the following format:

1. Direct reference

Direct quotation refers to completely copying some sentences or paragraphs from the original text into your own paper. When quoting these contents, you need to enclose them in quotation marks, followed by the author's name, publication year and page number.

For example, according to Smith (20 10), "…" (page 45).

2. Indirect quotation

Indirect quotation refers to the restatement of some contents in the original text, rather than direct copying. When quoting these contents, you need to add the author's name and publication year at the end of the sentence.

For example, according to Smith's research (20 10).

3. Cite multiple authors

When there are multiple authors in the original text, it is necessary to list the surnames of all authors in the reference mark and separate the last two authors with the "&"symbol.

For example, according to the research of Jones, Smith and Johnson (20 12).

4. Reference network resources

If you cite network resources in your paper, you need to include the title of the page, the author's name (if any), the website name, the publication date and the website address in the citation label.

For example, according to the report of xxx website (20 19), ...

The above are some commonly used citation formats, but the specific formats need to be determined according to the requirements of schools or periodicals. After marking, please carefully check whether each reference mark is consistent with the contents in the reference list, and ensure that there is no omission or repetition.
