7. How to describe the details of the high school essayFirst, choose the best point of the details of the description (a) Comprehensive description, the first step is to select the point of selection point of selection point of the "point" should be to the center of the "point". "should be the center of the role of the" point "only" point "in place, so as not to run away from the topic and bias.
For example, to "mother's love" as the topic, we can choose the point of mom to add a coat to their own action point, it can be the mother to watch the state of their own appearance point, can be to tell themselves how to behave in the language of the point, etc., in fact, the point of the selection in a sense and the selection of material related, but no matter which point, should be The expression of "mother's love" theme.
Because "if the skin does not exist, the hair will not be attached?" The most expressive of the theme of the "point" is that we need to write close-up and colorful rendering of the place. So, what kind of point to choose the details of the description is the best? Lao She said: "The most difficult place to describe the character is to make the character can stand up.
We all know that the use of occupation, class, ethnicity and other characteristics, to help form a unique personality; but these things do not necessarily make the character active. We must always show him in action.
Each action clearly and forcefully show him a little, he is more and more lively, the more real. In this way, the character's sensibility can be deep and vast."
The meaning of Lao She's passage is - only successful description of the character's movements, in order to make the reader really feel that the author's pen is a vivid character, his spiritual world can be fully demonstrated, the image can really stand up. See the wonderful action description for the important role of showing the character image.
Action description is one of the important methods of characterization. Every action of a character is constrained by his own thoughts and personality.
The successful description of the characteristic actions of the characters can explain the identity and status of the characters, can reflect the process of the psychological activities of the characters, can show the character traits of the characters, and sometimes can promote the development of the plot. Thus, we believe that in the narrative essay should choose the most expressive theme of the "action point" to action detail description, supplemented by portrait detail description, language detail description, psychological detail description and environmental detail description, etc. for a comprehensive description.
Choose the most important thing in the process of an action point to describe, supplemented by other methods of description, other perspectives, in order to focus the power of the language to a place to maximize the performance of the text. If the action occurs before, in the process of occurrence, after the end of the situation and so on all the original record, the article has no focus, we can only know the characters of each step of the content; and easy to form a running account, the length of the long, ink and ink, boring and bland.
This is the students in the recounting of things, the most likely problem. Action in the process must have a wonderful highlights, grasp the highlights of the specific description, not only can highlight the key parts of the matter, showing the character traits, inner activities, attitude, quality of thought, etc., but also to the reader to leave a strong and deep impression.
Details to "fine", to see the big picture. The description should be closely linked to the whole text, so that the details of the description and the plot of the whole story closely together.
Of course, the details of the description can be said to be a writing skill, different articles, different subjects, different genres, which should be seized in the details of the description, but also need to practice writing, the guidance of the exercise, the appreciation of the beauty of the article. More importantly, in the usual work, we have to "detail description" to evaluate the students' work, enriching the students' work evaluation system.
In this way, students in the work will be thinking about this, this to conceptualize, to achieve "twice the result with half the effort" effect. (b) Selected examples and comments on the fragment a day, we have a geography class, a student and the teacher backtalk.
This matter somehow reached the ears of the classroom teacher, only to see her pace into the classroom, scanning everyone, asked: "Who did it? Stand up! You can be sentenced to a lighter punishment." There were only four sounds in the classroom: the teacher's footsteps, our breathing, our heartbeats, and the ticking of the clock.
"Stand up! Don't hold everyone up!" Since it was time for class to end, everyone floored it. "Exactly!" The class responded.
He stood up, his face red. The teacher first praised him for his honesty, then took him calmly to the office.
Comment: This clip is a common "point" in the school classroom, and it's not a big deal, but it's very real and concrete. There are the actions and words of the class teacher, the actions and reactions of the class, and the actions and performance of "him".
It can be seen, in the choice of a comprehensive description of the "point", do not have to choose those earth-shattering big "point", as long as in line with the theme, can play a small to see the effect of the big. And write a real thing, true feelings and true feelings.
And this "point", in our life is not abound? The world is clear all the article ah. The second fragment of the "Come on! Come on!"
He swung his body back and forth, as if building up his strength, and when he was moving forward again, he shouted, "Hey!"

The author observes very carefully and sees Isamu's movements in turn - "swinging," "yoyoing," "pulling," "moving," and "pulling." "moving," "straining," "approaching," "exceeding" the bar, etc.; he heard him shouting "Hey!" ; observed his demeanor -.
