Argumentative writing is to discuss problems, of course, there must be ideas, that is, there must be inevitable internal relations between all parts of argumentative writing. As we all know, argumentative writing is an argument. After you make an argumentative argument, you should put facts and reasons, so that your argument can be convincingly established. Therefore, there should be a causal relationship between the central argument and the sub-argument, that is, the central argument is "fruit" and the sub-argument is "cause". This causal connection is the "case" of argumentative writing thinking.

As an argumentative composition of senior high school students, there should be a causal relationship between at least the central argument and the sub-argument, and between the arguments.

After students put forward the central argument, they can find the direction of putting forward the sub-argument as long as they ask a "why" around the central argument. For example, the central argument is that "only persistence can sublimate people's ideology and morality and achieve something." After a little analysis, we can find that this view is talking about the importance of persistence, so the argument should answer the question of why persistence is important, so we can demonstrate it from two dimensions: why and what results. For example, "persistence is a kind of persistence, turning despair into hope", "persistence is a kind of belief, making the ordinary noble" and "persistence is a duty, making the ordinary great". If we want to test whether these three sub-arguments and the central argument are necessarily related, we just need to add "because" before these three sub-arguments and "so" before "persistence is very important" and read them together.

Similarly, there should be a causal link between arguments and argumentative essays. For example, after the sub-argument that "persistence is the duty to make ordinary and great", it can be discussed as follows: "The persistence of border guards makes the country stable and peaceful; The persistence of the people's teachers has made peaches and plums all over the world; Angels in white's insistence made the disease yield. " Another example is the argument that "freedom is the flight of ideas": "Action can be subject to objective reality, but ideas will always enjoy absolute freedom. With this freedom of thought, Li Bai, a poet, was born. This is Li Yu, who is still in prison and lamenting that' the old country is unbearable to look back on the moon'; Haizi, a talented poet, yearns for' facing the sea and blooming in spring'. In short, because of this freedom of thought, society will continue to make progress under its traction and create a human miracle that will never go down in history. "
