1. Give example and explain of shape of research article or thesis.

After you have spent some time finding your sources and absorbing the information, you should then be able to come up with a thesis statement that tells the reader how you will interpret the significance of the subject matter. This statement is a road map for the research paper, telling the reader what to expect.

The body is the largest part of a research paper; in it you collect and arrange evidence that will persuade the reader of your argument. It should, therefore, have a logical organization. If the paper is long, it is a good idea to partition the body into sections using headings and sub-headings. This includes using parenthetical citations when referencing another author's work in the body of your text.

When you write your scientific article,you may start your Introduction by describing the problem you are trying to solve, or the aim of your work, but as you will see when you examine published work, this is not how most research papers begin — and therefore it is not the best way for you to begin.

The introduction typically describes the scope of the document and gives the brief explanation or summary of the document. It may also explain certain elements that are important to the essay if explanations are not part of the main text. The readers can have an idea about the following text before they actually start reading it.

2. Give a definition of introduction section in a research article or thesis.

In an essay, article, or book, an introduction (also known as a prolegomenon) is a beginning section which states the purpose and goals of the following writing. This is generally followed by the body and conclusion.

The introduction typically describes the scope of the document and gives the brief explanation or summary of the document. It may also explain certain elements that are important to the essay if explanations are not part of the main text. The readers can have an idea about the following text before they actually start reading it.

The introduction should capture our readers’ interest, making them want to read the rest of your paper. Opening with a compelling story, an interesting question, or a stirring example can get your readers to see why our topic matters and serve as an invitation for them to join us for an engaging intellectual conversation (remember, though, that these strategies may not be suitable for all papers and disciplines)

Our introduction conveys a lot of information to our readers. We can let them know what our topic is, why it is important, and how we plan to proceed with our discussion. In most academic disciplines, introduction should contain a thesis that will assert our main argument. It should also, ideally, give the reader a sense of the kinds of information we will use to make that argument and the general organization of the paragraphs and pages that will follow. After reading your introduction, your readers should not have any major surprises in store when they read the main body of your paper.

Grammar and writing skills are the important part in the Introduction. We should use the Present Simple and the Present Continuous tenses in Introduction, also we can use Active and Passive voice in our sentences.
