Generally speaking, English argumentative essays tend to get to the point, that is, they should state their positions in the opening paragraph.

However, the specific situation is analyzed. If you give the topic, it is a choice. It is usually written like this: the first paragraph shows your own point of view, the second paragraph discusses the opposite or opposing point of view, the third paragraph is on your own point of view, and then ends.

On the other hand, in IELTS writing, there are often such topics as discussing the views of both sides and giving your own views. At this time, the opening paragraph doesn't need to make a position immediately. You can rewrite the title first, the second paragraph discusses one point, the third paragraph discusses another point, and the fourth paragraph gives your own point of view (which can also be used as the ending paragraph).
