Short commentary belongs to news commentary, which is essentially an argumentative style. When writing, you should follow the general argumentative writing style, with clear views, sufficient arguments, refined language and reasonable argumentation, that is, strict logic.
Therefore, the most important information we get from the original text is the viewpoint. Generally speaking, investigation is a more positive topic. For example, take "the craftsman spirit is imperative" as an example and write a short comment. In essence, I hope you can strengthen this view through argument, that is, make it clear with reasons and examples-the craftsman spirit is really important, and that is to explain the meaning of the craftsman spirit.
This kind of topic, the general practice is to sort out the original text, summarize the original text into three or four benefits of craftsman spirit, and then find data and examples from the original text to supplement your argument (one of the benefits). The structure of the last article is as follows:
Craftsmanship is imperative at the beginning: simple paving and craftsmanship are imperative (central argument).
The second paragraph: the advantage of craftsmanship is 1 (fill in some examples from the original text).
The third paragraph: the advantage of craftsmanship is 1 (fill in some examples from the original text).
Paragraph 4: The advantage of craftsmanship is 1 (fill in some examples from the original text).
End: simple paving+re-emphasizing the importance of craftsmanship.
