When quoting documents in a paper, you can use different annotation formats, among which the following formats are more common:

1, author-publication year system (APA format): indicate the author's surname and publication year in brackets in the quotation part, for example: (Smith, 20 10). If there are multiple authors, use the "&"symbol to connect them, for example: (Smith &；; Johnson, 20 15). If the quotation directly refers to the contents of the document, it is necessary to put quotation marks in the text and indicate the page number at the same time, for example, (Smith, 20 10, page 23).

2. Numeric system: the number of the document is indicated in brackets in the reference part, such as [1], [2], etc. Generally speaking, these figures are arranged in the order in which the literature first appeared.

3. Author-page number system: indicate the author's surname and the page number of the cited page in brackets, for example: (Smith, page 23).

It should be noted that the annotation format used in the paper should follow the requirements of academic journals or tutors to ensure the standardization and rationality of the paper.

Matters needing attention in writing a paper include:

1. Clarify the research questions and objectives, and determine the theme and structure of the paper;

2. Read the relevant literature deeply and carefully sort out and quote the existing research results;

3. Carry out empirical research rigorously and scientifically, and collect, sort out and analyze data;

4. Pay attention to the language and format of the paper to ensure that the article is clear and easy to understand, and the typesetting is neat and standardized;

5. Abide by academic integrity and do not copy or tamper with other people's research results;

6. Revise the paper in time, review and polish it repeatedly to ensure the excellent quality of the paper;

7. Respect the opinions of the evaluation experts, seriously answer the evaluation opinions and make necessary modifications.

In short, writing a good thesis requires a serious, rigorous and meticulous attitude, and at the same time, you need to have enough understanding and cognition of your own research field.
