The structure of the article refers to the relationship between the components of the article.

Common ones are: parallel type, progressive type (step by step) and total score type.

Let's say it in the vernacular. What are coordinates? For example, if you want to write an article about your three good friends, if you write Zhang San, Li Si and Wang Wu respectively, these three paragraphs are called juxtaposition;

What is progress? In the first paragraph, these three friends often play with me. In the second paragraph, these three friends usually study with me to help me improve my grades. In the third paragraph, I wrote that these three friends saved my life. The relationship here, the description of "good friends" is getting deeper and deeper, which is called progressive;

What is the total score formula? You came up to write a paragraph saying that these friends are very good with me at ordinary times, not only playing with me, but also studying with me, which saved my life. Then you describe these three things separately. Because there is a summary, this is the total score structure, and the similar total score structure is needless to say.

We can also make an analogy with your familiar scientific thinking: (triangle, square, circle) This is called juxtaposition; (triangle, isosceles triangle, equilateral triangle) This is called progression; (shape: triangle, square, circle ...) This is called total score.

What are language features? It refers to the expression style of an article that is different from other articles.

For example, if you tell the teacher that you want to go to the bathroom:

"Report teacher, I want to go to the toilet": the language style is accurate, concise and simple.

"Teacher, I ate a rotten banana this morning, and now I have a thread in my stomach, which makes me feel terrible. You see, the sweat on my head is rolling down, and I, I want to go out. " The language style is vivid.

"Teacher, I feel sick to my stomach. Can I go out? " : The language style is implicit.

"Hey, teacher, I want to shit"; The language style is vulgar and rude;

"Tell the teacher that my ass wants to vomit": humorous language style.

In short: this is the way of speaking.

Expression: refers to the special sentence structure used to express meaning, for example, if you want to say that an apple is delicious.

This apple tastes sweet and crisp: the technique of positive description

As soon as my father took a bite of this apple, he couldn't wait to take another bite: the technique of profile description.

Sugar is sweet, nuts are crisp, and chocolate smells delicious, but when I see apples, I will throw them aside: the way of contrast.

That bitter gourd made me almost cry. After eating this apple, I forgot all about eating bitter gourd.

This apple looks wrinkled, but after a bite, I found it really sweet: the way to raise it first and then suppress it.

The sweetness of this apple dances on the tip of my tongue, tempting me: rhetoric (personification)

This apple is probably the first delicious apple in ancient and modern times, and the emperor has never eaten it. Rhetoric (exaggeration) skill

……

There are many ways of expression. According to these examples, you can easily understand the concept.
