It is the most concise summary of an applied linguistics paper and the essence of a research paper. In the overall format of applied linguistics papers, the abstract is in front of the paper, but it must be noted that the abstract is the summary after the paper is completed.

There are two main points in the importance of writing: (1) It is convenient for readers to know the main contents of the paper, what the author is studying, what research methods and means have been adopted, what major achievements or progress have been made, whether it is creative or innovative, and so on. They often judge whether it is necessary or worthwhile to spend time reading the full text carefully by reading the abstract; (2) It provides convenience for other researchers to search, so that readers can understand the basic content and main points of the paper before reading the full text, which plays a role in prompting and guiding.

The classification of abstract mainly includes informative abstract, indicative abstract, critical abstract and descriptive abstract, among which informative abstract and indicative abstract are the most common. Information summary, also known as report summary, mainly introduces the main purpose, main methods, main achievements and analysis of the research topic, and gives a more comprehensive hint to the content of the paper. Provide readers with as much qualitative or quantitative information as possible within a limited number of words, which fully reflects the innovation of this study; The so-called indicative abstract is a concise description of one's own research results (including data, opinions, opinions, results, conclusions, etc.). ), and often only a few words or nothing about the research methods, means and processes involved, in order to let readers have a general understanding of the main contents of the research.
