How to write an expository essay Be fast! I have an urgent 20

If it is an item, write about the shape, characteristics, structure, purpose, and process of use.

Animals: appearances, impressions.

Fruits and vegetables: shape, color, taste, type, origin, yield, nutrition.

People only pay attention to the reading of expository essays, and the writing of expository essays is often ignored by everyone, teachers do not pay attention to it, students are not interested in it, and the probability of asking you to write an expository essay during the exam is not high, therefore, the writing of expository essays has become a weak link in middle school Chinese teaching. In my opinion, the writing of expository essays should attract everyone's attention. Among expressions, description is one of the most basic expressions.

Think about it, if a person can't even understand the words, how can he discuss and lyrical? The new curriculum standards also explicitly stipulate that "simple expository essays should be written and clearly understood". Expository essay is a kind of practical style, the writing rules of this style are easy to grasp, grasp the characteristics of things, determine a reasonable writing order, use appropriate explanatory methods, pay attention to the accuracy of language use, etc., you can write a good expository essay.

Narrative and discussion** are difficult to teach you an effective way to write, and even if they are taught to you, they may not work. That being the case, I'm going to talk about how to write an expository essay.

First of all, the purpose of the writing should be clearly stated.

The purpose of expository writing is to introduce objective things and introduce scientific knowledge, so that readers can understand and understand it. This requires that the language of the explanation should be easy to understand. The purpose of writing a narrative essay is to move people with emotion and move people, and the purpose of writing a narrative is to convince people with reason and convince people.

They are very different in terms of the purpose of writing.

Second, write around the characteristics of things.

The characteristics of things are the unique properties of the things themselves, the different characteristics of this thing from other things, and the differences between individuals and classes. Only by grasping the characteristics of things can we explain things in detail and concretely. For example, if you want to explain "spider", you need to understand the characteristics of spiders, the most prominent feature of spiders is that they can secrete a kind of mucus, form silk, and use it to prey on insects, which is also the most different point between spiders and other small animals.

To explain spiders, you have to focus on this, otherwise, it will be difficult to understand. In order to explain things around their characteristics, it is necessary to carefully observe and study things, find the difference and connection between this thing and other things, and make vertical and horizontal comparisons between the things themselves. This is true of expository texts that illustrate things, and so is expository texts that illustrate things.

For example, the article "The Dead Sea Does Not Die" is an explanatory essay that first introduces people to the difference between the Dead Sea and other lakes in that life cannot survive in the Dead Sea, and the waters of the Dead Sea cannot drown people. Why these situations occur requires us to get to the bottom of the matter, find out the causes, and explain these phenomena.

If we find the cause, we will also find the essential characteristics and essential properties of things, and introduce things from phenomena to essences, which requires the writer not only to know what it is, but also to know why it is so. From this point of view, grasping the characteristics of the object of explanation is the key to writing an expository essay.

That's all there is to it.

How to write a good expository essay?

1. It is necessary to grasp the characteristics of the description object.

What are the characteristics of things? Characteristics are the symbols and signs that distinguish this thing from others. It often expresses the color, texture, spatial location, shape, temperature, cause, principle, change process, internal structure, habits, performance, style, etc. of things.

How do you grasp the characteristics of things? First, we must observe carefully. Use sensory organs such as eyes, ears, mouth, nose, body, and skin to see, hear, taste, smell, and touch the things to be explained, so as to accurately and comprehensively grasp the characteristics of things.

Second, we must think deeply. By comparing the object of explanation with similar things in many aspects, analyzing their similarities and differences in depth, and grasping their "differences", we can grasp the characteristics of the thing and grasp the key points of the explanation.

2. Arrange the order of explanation reasonably.

There are three common order of description: chronological, spatial, and logical. If it is to illustrate the process of development and change of things, the order of "time" is adopted, which can be from ancient to modern or from modern to ancient.

If you want to explain the orientation and shape of things, you should use the order of "space". It can be from near to far, from far to near, from left to right, from south to north, from low to high. If it is to clarify certain operating processes, it is explained in the order of "procedures", that is, according to the sequence of operation behaviors.

If the purpose of the explanation is to explain the facts, it is necessary to use a "logical" order: the order is generally arranged according to cause and effect, primary and secondary relationships. For example, the description of Zhaozhou Bridge and Lugou Bridge in "Chinese Stone Arch Bridge" adopts the logical order of geographical location, construction time and structural characteristics, the description of the buildings of the Forbidden City in "The Palace Museum" adopts the spatial order, the description of the phenological landscape of the four seasons in "The Language of Nature" adopts the chronological order, and the description of the factors affecting the occurrence of phenological phenomena adopts the logical order from primary to secondary, from large to small.

3. Appropriate explanation methods should be adopted.

Common methods of explanation include: examples, column data, analogy, categorization, diagramming, comparison, interpretation, imitation, quotation, definition, etc. For example, to illustrate the long hours of sunshine in desert areas

There are 3,000 hours of sunshine a year, compared to 1,500 hours in the Yangtze River basin and 2,500 hours in northern China. "By listing the data and making comparisons, it vividly highlights the characteristics of long sunshine hours in desert areas. For example, to show that water is not white, you can compare water with soy milk.

Compared with soy milk, the white color is soy milk instead of water. Water, no color.

4. The language should be accurate, concise and popular.

The representation of time, space, quantity, scope, degree, nature, procedure, etc., all require accuracy. The language of the expository text is accurate, and it is not necessary to use exact numbers, but also approximate numbers. For example, "approximately", "around", "maybe" and "estimate" can also reflect the accuracy of the explanatory language.

On the premise that the language of the expository essay is accurate, the language style can be both plain and lively. For example, the use of metaphors, personifications, dialogues, self-descriptions, storytelling, and other explanatory methods in writing can enhance the vividness of explanatory language.

Write it yourself, I'm sure you've already written it.

Go straight to the topic and describe it. Start with the appearance, and then start with its history, its internal structure. It's better to take a look at similar articles.

The pen is an indispensable part of our life Teachers work, students do homework, etc., we have to use the pen all the time, but there are still many inconveniences in the pen in real life, for example, when writing a fountain pen, it is often inked, and it is still very cold to write a fountain pen in winter, so I want to invent a magic pen

The pen of the future is a cylindrical banquet blind, and the function of the pen can be dora The pen of the future is equipped with an automatic controller and an ink reservoir When your ink is finished, the ink will automatically be added to the nib of the pen This pen is equipped with a miniature air conditioner in the middle As long as you press the green button on the pen, it will be very cool You will not feel hot when writing in the summer In winter, it will be very cold when writing in the air, so you press the red button, and there will be heat coming out immediately, which is particularly comfortable when writing There are four sensor lights at the upper end of the nib It will illuminate normally when it is twenty centimeters away from the book, and if it is too close to the book, it will emit a dazzling light, so that you can't see the words you write clearly With the sensor light, you don't have to worry about your eyes being myopic In addition, there is a typo discriminator in the pen, if you write a wrong word, it will make a "beep" sound to remind you, so that you will not write a typo There is a small *** installed on the top of the pen to relax by listening to songs when you are writing homework.

This pen can not only allow us not to make typos, but also improve our interest in learning, so that we can learn in a relaxed and happy way.

You can use the appropriate technique:

1.The bridge hole of the stone arch bridge is arc-shaped, like a rainbow.

For example, you can make the image of the object you want to illustrate palpable. ）

2.Zhang Jiazhen of the Tang Dynasty said that it was "peculiar, and people don't know what it does".

Citations can add to the persuasiveness of the article).

3.The Zhaozhou Bridge is very majestic, with a total length of meters, a width of meters at both ends, and a slight narrowness in the middle, with a width of 9 meters.

Column numbers to reflect accuracy).

4.When the Yongding River is watered, it is very violent, and the embankments on both sides of the river are often washed out in the past, but this bridge has never had an accident, which shows its solidity.

For comparison, it is easy to highlight the characteristics of the object being illified. ）

5.These stone carved stone lions, some mother and child hug each other, some turn heads and ears, some like listening to the sound of water, some like watching pedestrians, thousands of forms, vivid. ( facsimile appearance, so that the object to be illustrated is more specific and more vivid.) ）

6.According to the construction materials of the screen and the magnificence of decoration, it is divided into gold screen, silver screen, brocade screen, painting screen, stone screen, wooden screen, bamboo screen, etc., so there is a difference between elegance and vulgarity in art, and it also reveals the different economic and cultural levels of users.

Divide into categories so that readers can understand the types of screens. ）

7.Suzhou gardens pay attention to the beauty of pictures in every corner. A few bunches of books and grass are planted next to the steps. (For example, increase the credibility of the article).

8.The god of the big arch touched the shoulders of each with two small arches. This creative design not only saves stone and reduces the weight of the bridge, but also increases the amount of water passing through the bridge and reduces the impact of floods on the bridge when the river swims and swells.

At the same time, the arch is added to the arch, and the bridge body is also more beautiful.

to make the reader understand the ingenuity of the design. ）

9.Carbon dioxide is a carbon atom and two oxygen atoms are burned as carbon dioxide.

You can also add anthropomorphic files, metaphors, comparisons and other methods.

Not enough, ask me again! Remember to give extra points!
