How to write scientific discourses and sci-fi compositions ~?

Scientific expository writing is expository writing first, so it must first meet the requirements of expository writing and be rigorous and accurate.

Material data are required to be true and reliable, and the text is rigorous and accurate.

Taking "explanation" as the main expression can be dull or vivid.

Explanatory articles are not papers, but generally popular science. Language is easy to understand, and there are few abstruse terms.

Science fiction is generally a novel, so we should grasp the three elements of the novel: characters, plot and environment.

Because it is fantasy, imagination is very important. It needs certain scientific knowledge and elements, but it doesn't need to be accurate and true, as long as it can be justified without violating the existing scientific system.

Generally speaking, it is the thinking and expression of the influence of advanced science and technology at present or in the future, and the prospect and imagination of the future should be logical, so it can show the thinking ability well.

In order to express the scientific elements, description is also essential, but it must be skillfully integrated into the description of the plot and environment, and it is forbidden to give a long explanation.

Science fiction may also appear in other genres, such as expositions, reports and letters ... No matter how you write it, you should pay attention to the requirements of the genre itself.
