The language style of expository essays is divided into plain expository essays and vivid expository essays. Supplements: 1

Plain expository essays: Plain expository essays are often straightforward about the object. No description, no exaggeration, no overtones, like mathematics, physics, biology and other textbooks.

Expository essays that use plain explanations are generally articles that explain scientific principles, explain the production process and steps, or introduce buildings, etc. It is suitable for expository essays with scientific and strong coherent explanations, and it is more to give readers a rational understanding. 2.

Showing up and using life feelings can make the article more authentic and interesting to life on the basis of accuracy, which is easy for people to accept; 3 Proper use of narration and description can bring the things that are illustrated to life rather than boring. Most of the expository essays that use vivid language are literary sketches and popular science books, which not only give people knowledge, but also emphasize the vividness of the article.

3.The difference between the two: the plain expository text is purely explanatory in the way of explanation, the language is simple and concise, the content is specific, and it can be understood by people after reading.

Such as all kinds of textbooks, technical information materials, experimental reports, manuals of natural science, etc. The vivid expository essay is mainly illustrative, supplemented by narration, description, lyricism and other expressions, and often uses some rhetorical methods to visually introduce things or explain things, so that readers can get the enjoyment of art while gaining knowledge. According to the different characteristics of the explanatory language and the different use of expressions, the expository text is divided into two types: plain expository text and vivid expository text.

A vivid expository essay is also called a literary expository essay.
