the second part

Three emotional colors: positive, negative and neutral.

Part VII

Eight common rhetorical methods:

(1) Metaphor-makes the language vivid and adds color to the language. 2 personification-writing things into adults makes the language vivid.

3 exaggeration-highlight something or emphasize a feeling. 4 parallelism-enhance the language momentum and enhance the expression effect.

⑤ Duality-make the language concise and neat. ⑥ Quote-enhance the persuasiveness of language.

⑦ Ask questions-arouse readers' attention and thinking. ⑧ rhetorical question-plays an emphasis role and enhances the positive (negative) tone.

Part VIII

First, master the explanation method. What explanation methods are used? What's the role?

Mode: Method+Effect+Features

? Explain the characteristics of (the object of explanation) by means of explanation. ?

1 classification: explain separately to make it clear.

2 Citation: Citation highlights both persuasiveness and interest.

3 analogy: vivid image, indicating that the article is more interesting.

Interpretation: further explanation, so that readers have a further understanding.

5 examples: explain the characteristics of the explanation in detail to make the explanation more specific and convincing.

6 Definition: It accurately and concisely reveals the essential characteristics of "the" and makes the explanation more rigorous.

Compare: To compare and highlight the characteristics of.

Eight columns of figures: explain with specific data to make the explanation more accurate and convincing.

9. List the chart: explain the characteristics in detail to make the explanation more concise and intuitive.

10. Imitation: Vividly illustrates vividness.

Second, realize explanatory language.

Can modified and restrictive words (such as basic, approximate, comparative, general, few, most, more, maybe, often, then, most, major, almost) be deleted or replaced? Why?

Language accuracy class answer method:

1. What's so good about words?

★ Answer method: Illustrate the characteristics of things vividly (accurately) with words, which can stimulate readers' interest (in line with the actual situation, scientific).

2. Can the words added in the article be deleted? This topic is divided into four steps:

A: Judging, generally speaking, it cannot be deleted.

B: Explain the meaning of this word in this sentence and limit it in degree, state, nature and scope.

C comparison: it is to compare the difference between deleting and not deleting this word, and it must be analyzed in combination with specific sentences. Not in line with reality, original intention, etc.

There must be a sentence at the end of d: this reflects the rigor, accuracy and scientificity of the interpretation language.

★ Answer method: cannot be deleted. Because the word means that after deletion, the meaning of the sentence becomes? This is inconsistent with the meaning of the text. It embodies the rigor, accuracy and scientificity of the explanation language.

Combined with the content of the article, give examples, make suggestions, express opinions or imagine the future.

1, common writing methods and expression skills

Association, imagination, symbolism (expressing meaning through objects), comparison, contrast, contrast, seeing the big from the small, expressing emotion through scenery (blending scenes), paving the way and foreshadowing, taking care of before and after (echoing), describing directly (indirectly), promoting and restraining (promoting first and then restraining).

(1) Symbol: Lyrics are expressed by chanting things, and the author's feelings are often expressed tactfully with the help of certain characteristics of certain plants, animals and objects.

Function: First of all, it shows abstract things as concrete and perceptible images. Secondly, you can make the article more subtle and give it profound meaning with what is in front of you.

(2) Set off: Set off the body from the front and back. Function: Highlight the characteristics of ontology.

(3) Contrast: Compare two opposite things or two opposite aspects of a thing.

Function: clearly highlight the characteristics of the main thing or the main aspect of the thing.

(4) Lyricism through scenery: express the author's sincere thoughts and feelings by describing concrete and vivid natural scenery or life scenes.

Function: Blend the scenes to make the article poetic.

(5) First suppress and then promote: first deny or belittle the image of things, then dig deep into the characteristics and inner meaning of things, and then affirm and praise things. Function: Highlight the characteristics of things (people).

(6) Side (indirect) description: The side highlights the character, conduct and skills of the characters, making the structure of the article more concentrated and compact, and the expression more concise and concise.

The combination of direct description and indirect description can make the characteristics of the characters or scenery described more distinct and prominent.

(7) bedding: function: the content is both before and after, and the plot is seamless.

(8) Care: Narrative: Make the article seamless, with a strong sense of integrity and highlight the theme.

Argumentative essay: strengthen the argument. Prose: Expressing emotions repeatedly, increasing the depth of emotions.

(9) Lenovo: the psychological process of thinking of another thing from one thing.

Function: enrich the content of the article, make the characters fuller, the personality more distinct and prominent, and the plot more vivid and touching.

(10) Imagination: the psychological process of creating a new image on the basis of the original perceptual image.

Function: Serve for shaping image and expressing theme. Make readers accept the influence of beauty.
