The community of scholars has rules that govern how dissertations, theses and other academic papers are composed and formatted. Academic convention has established what is acceptable and what is not.
The three structural parts of a well-constructed paper 完整文章结构三段式
Having researched a subject and obtained some mastery of the language, an academic writer can begin to write. The writer's pre-writing activities are the foundation and the framework for the paper. Without the advance work, a paper will be rickety in its presentation and weak in its material content. No successful academic writer ever writes a paper based on shaky knowledge.
Academic papers share a three-part structure with other conventional written media. Essentially, the paper should have a beginning, a middle, and an end, which usually are referred to as introduction, body, and conclusion. These are fundamental to any attempt at communication. Literature sometimes departs from this model, but academic literature has no such license.
The introduction should accomplish two tasks: (1) Present the paper's general subject and (2) present the writer's distinguishing proposition or thesis on the subject. An example: Were the subject William Shakespeare, the Bard would be introduced with enough detail to fully identify his work. This would be followed by the proposition that Shakespeare was, let's say, a fraud.
At once, the reader knows where the paper is headed. Its longitude and latitude are yet to be revealed, but its direction is set. In the body of the paper that follows, the writer then presents the rich lode of material supporting the thesis. This main content should flow naturally from a rough outline developed during the research process, in which both mind and materials are organized.
Having effectively presented in the body of the paper the researched and original material, the writer then must conclude. This is not an insignificant section of the paper. It brings together the paper's key elements in a few sentences, giving the reader a capsule account. This summary and restatement should affirm all that went before and impart confidence in the integrity of the paper.
The structure of an academic paper is progressive, yet it is circular, too. After reading the conclusion, a reader should be able to look back to the introduction and consider the paper a promise kept. While each section has a separate function, the three sections are interconnected in their purpose and conviction. An irresolute paper is a failure of scholarship and of structure.
