What is the idea of explaining writing?

What are the writing ideas of scientific and technological exposition?

Scientific exposition has been puzzling the majority of candidates. How can we break through the bottleneck and get the ideal score? Based on my own teaching experience, the author discusses the problem-solving ideas of this kind of topic with you. As soon as candidates come into contact with the article, they should browse the full text as quickly as possible, and quickly summarize what the article mainly says, what aspects it talks about, what main viewpoints it has, what research results the author has demonstrated, and so on. It is necessary to generate questions from the text and then form preset knowledge points. The scientific and technological expository text mainly conveys information, which requires us to screen out important concepts and sentences from the text and understand them, so as to establish a purposeful screening consciousness. For important concepts, we should pay attention to analyze the relationship between first and later, phenomenon and essence, possibility and reality, condition and result, part and whole, affirmation and negation, and this concept and other concepts. For important sentences, we should step up processing, extract the trunk and grasp the main meaning. 1. There are always several paragraphs in this article. What is the center and what kind of topics are around it? 2. The general content of each paragraph should be summarized in just a few seconds. 3. While skimming, sketch out the terms that appear in each paragraph, which can be used as marks to pave the way for finding answers.

What is the center and what kind of topics are around it? 2. The general content of each paragraph should be summarized in just a few seconds. 3. While skimming, sketch out the terms that appear in each paragraph, which can be used as marks to pave the way for finding answers. For example, No.5 of Science and Technology Description Volume 1 in 2006: From the original text, the following explanations of the relevant contents of the "Argos" plan are correct: (a) a) A global ocean observation network consisting of 3,000 buoys floating up and down with ocean currents is used to monitor sea water changes. B. Collect relevant information of deep-sea current with buoys equipped with seawater temperature and salinity sensors. Zheng Deyang C, official website of Harbin Normal University, used the information collected by the on-orbit satellite to control the whole working process of the buoy. D. Analyze and study the heat capacity information of deep seawater verified by buoys, and draw a "marine meteorological map". The correct answer is item B. This question examines students' ability to understand the meaning of words in the text and their ability to discriminate and screen important information in the text. Item A "Buoy constitutes a global ocean observation network" is not properly expressed; Item C "Control of the whole process of buoy work" does not contain this information; The original words of item D in the material are "I hope to draw a marine meteorological map". Carefully analyze the topic, grasp the key words, make clear the direction of the question, and then go back to the text to find the answer. ; Finding the answer you need or the basis for judging the options in the text is the first step. Important information includes basic concepts, new ideas, words with special reference significance, and important sentences that explain concepts, indicate writing intentions or the main idea of the article. The key is to find the original text corresponding to the option. Some may find several places, but generally only one place meets the requirements. It is necessary to distinguish and compare and extract the required content. For example, the stem of the question mainly asks the meaning of a technical term. Candidates should quickly find out which paragraph the term appears in, and then make a summary according to the context to see which one is closest to the answer. In addition, if the question is the understanding of a sentence or a paragraph, the examinee will return to the text. When skimming the text, the content of each paragraph has been summarized. Therefore, further intensive reading is needed, that is, summarizing the main points of this paragraph, and finally extracting it, and then comparing it with the narrative in the title, so the answer is obvious. In 2004, the national college entrance examination Chinese exam questions explained the seventh question, examining the understanding of the concept of "human embryonic stem cells". The first sentence of the first paragraph explains the concept of "human embryonic stem cells". To understand a concept, we should grasp its most essential feature, that is, pay attention to the essential feature that distinguishes it from other things. To understand "human embryonic stem cells", we should grasp "blastocyst", "inner" and "inner cell group" in the early stage of human embryonic development. The "flat cells on the surface of blastocyst" in item A is the supporting tissue of embryo and is not included in it. Item C is the solution of "human embryonic stem cell" differentiation ... >; & gt

Induction of Basic Knowledge Points of Chinese in Junior Middle School

first part

Two common narrative clues: object line and emotional line.

Two language types: spoken and written.

Two ways of argumentation: argumentation and refutation.

Two explanatory languages: plain and vivid.

There are two types of expositions: expositions about things and expositions about things.

Two kinds of environmental descriptions: the description of natural environment-contrast the emotions of characters and render the atmosphere.

Description of social environment-explain the background of the times.

Two types of argumentation: factual argumentation and rational argumentation.

the second part

Three kinds of people: the first person, the second person and the third person.

Three senses: positive, negative and neutral.

The novel has three elements: the characters (the main characters depend on whether the theme of the novel can be expressed), the plot (beginning/development/* * */ending) and the environment (natural environment/social environment). )

Characters mainly master the reading skills of depicting characters through appropriate description methods and angles and reflecting their thoughts and personalities.

Plot mainly understands the basic content of each part and the methods and skills to understand and analyze the plot of the novel.

Begin to explain the background and pave the way for the following.

For example, at the beginning of Kong Yiji, the layout of Xianheng Hotel and the scenes of two different identities and positions of drinkers (short coat gang and long coat customers) were described, which explained the social background of the disparity between the rich and the poor and class opposition at that time, paving the way for the emergence of this special figure, Kong Yiji.

Develop the characters' personalities and embody their individuality.

Example: The development part of Kong Yiji tells the scene that Kong Yiji was laughed at for drinking at Xianheng Hotel for the first time. Through the description of Kong Yiji's image, manners, movements and language, this paper reveals his ideological character of poverty, self-deception, pedantry, pride and laziness.

* * * Show the conflict and reveal the theme.

For example, the * * part of Kong Yiji tells the scene that Kong Yiji was laughed at for drinking at Xianheng Hotel for the last time. It reflects Ding's bullying, ruthless and positive description of Kong Yiji's physical disability, and shows his tragic experience, thus profoundly exposing the evils of the feudal imperial examination system.

The ending deepens the theme and leaves some thoughts.

For example, in the ending of Kong Yiji, a group of meaningful words such as "about" and "indeed" not only add tragic meaning to Kong Yiji's tragic fate, but also leave readers with endless thoughts.

Environment mainly understands the role of natural environment and social environment.

The natural environment describes the natural landscape, exaggerates the atmosphere, sets off emotions, predicts the fate of characters, reveals the essence of society and promotes the development of plots.

Example 1: The * * part of "Kong Yiji" depicts a bleak atmosphere by describing the sad scene of autumn, which indicates the tragic ending of Kong Yiji's imminent death.

Example 2: My Uncle Yule * * and the ending part set off the cheerful, frustrated and depressed mood of the characters by describing two contrasting sea scenes ... >>

Looking for clues: title; Repetition of words or things; Lyric argument sentence 15. The appreciation of sentence paragraphs is considered from three aspects: content (unique writing style and material selection); Form (words, language features, rhetoric); Love (cultural value, significance, function, etc.). ) Summary of basic knowledge points of Chinese Part II: Narrative clue: object line and emotional line: oral and written language: argumentation and refutation: plain, simple and explanatory text: explaining things, explaining things: self-describing environment-describing social environment by comparing things-explaining background: factual argumentation. The second part of the argument has three names: the first name, the second name and the third name. There are three elements: positive meaning, negative meaning and sex theory. Things (determine the main things according to whether the theme can be expressed) plot (ending/development/* * */ending) environment (own environment/social environment) things mainly grasp the general description, and describe the image of things from the perspective of reflecting their ideological character. Analyze the plot and finally explain the background. Example: At the end of "Kong Yi", two identities of Xianheng Hotel are described, and two drinkers (customers of shorts and shirts) explain the disparity between the rich and the poor and the background of class establishment. Kong Yi's special field paved the way for the development of characterization. Example: The Development Department of Kong Yi described the scene of drinking in Xianheng Hotel in Kong Yi, revealing its portrait, manners, works and language. * * * Theme conflicts. For example, the * * part of "Kong Yi" describes the scene where drinking in Kong Yi Xianheng Hotel was laughed at. On the whole, it reflects Ding Ju's bullying and harsh description of Kong Yi's physical disability, shows his tragic experience, profoundly exposes the evil ending of the feudal imperial examination system, and deepens the theme. For example, the ending of "Kong Yi" is about that the truly meaningful words only add tragic significance to Kong Yi's tragic fate, leaving readers with a poor thinking environment, mainly to understand the self-environment social environment, self-environment description, self-landscape rendering atmosphere, contrast feelings, predict the fate of things, reveal the social essence and promote the development of the plot. Example 1: Kong Yi * * describes the sad scene in autumn, exaggerates the sad atmosphere and foretells the tragic ending of Kong Yi's death. Example 2: My Uncle Yule's ending generally describes two things that are more cheerful, lost and depressed than the bright seascape. Example 3: The full text of "The Storm" strongly describes the storm, but only advances the plot step by step, showing the tragic fate of pulling the cart and lamar, revealing the social environment and describing the social situation more deeply, explaining the background of the story and revealing the essence of society. Example 3: At the end of Kong Yi, the layout of Xianheng Hotel and the situation of drinkers are described. Three elements of argumentative writing: argument, argument and argumentation The structure of argumentative writing: asking questions (introduction), analyzing questions (paper) and solving problems (conclusion): three principles of indirect order, spatial order and logical order: conciseness, coherence and narrative: direct narrative, flashback and insertion (supplementary narrative belongs to insertion type) The third part has four literary genres: narrative and narrative. Four usages: declarative sentence, interrogative sentence, imperative sentence and sigh sentence; The fourth part tells the story: end, development, * * *, ending; There are five arguments in the fourth part: demonstration with examples, ... >>
