Based on the text Termite Kingdom , it is rewritten into a plain expository essay with a word count

As the saying goes: "A thousand miles of embankment collapses in an anthill". In 1998, the Yangtze River basin was hit by a catastrophic flood, and some dikes "gushing" were caused by ant infestation.

Of course, the "ants" mentioned here are not ordinary ants, but soil termites. Soil termites are secretive and hidden. It is likely that some of the earthen dams that appear to be intact have been severely damaged.

The small jeep speeding on the Jingjiang embankment actually fell into the earthen dam, and it is even more common for pedestrians and buffaloes to fall into the "trap" of the dam. So, why can tiny termites hollow out thousands of miles of embankments and destroy them in one fell swoop?

The results of scientific research tell us that termites in China can be roughly divided into three categories: wood-dwelling termites, earth-dwelling termites and civil amphibian termites. The termites that break the levee are mainly soil-dwelling termites, a type of termite that specializes in nesting in the soil.

Millions of termites in an adult nest live together in "organized, disciplined" groups. The society of termites has a strict division of labor: the queen ant and queen ant specialize in reproducing offspring; Soldier ants are responsible for security; Worker ants are the most abundant and are engaged in basic labor such as nesting and foraging.

The white nest can be up to two meters deep underground, the main nest is about 1 2 cubic meters, and there are more than 100 secondary nests around the main nest, and there are ant roads connecting the nests in all directions. Because soil termites continue to colonize, encroach and build nests in the embankment, the ant nests in the embankment are scattered. Once the flood season comes, the water level rises and the water overflows into the antway and anthill, there will be dangerous situations such as dike pipe surges, leakage and landslides; If it is not eliminated in time, the embankment will collapse and the consequences will be catastrophic.

Soil termites are a harmful insect to humans. Soil termite colonies are huge, multiplying rapidly, concealed habits, and destructive, and it is not easy to completely eliminate its damage. In recent years, scientists have made a number of research achievements in this field, and the vision of "a thousand miles of embankment, impregnable as gold" will surely become a reality.

Do you think anyone would be stupid enough to do something like this?

The rigor of the content, the coherence of the explanation, and the accuracy of the language.

The rigor of the content: truthfully reflect the objective things, grasp the characteristics, essence and laws of things, and give readers a correct understanding.

Explanation is organized: written chronologically similar to a narrative; Write in spatial order to pay attention to the observation points, pay attention to the position and direction of the surface and the inside, the size, up and down, front and back, left and right, southeast and northwest, etc.; When writing in a logical order, we should pay attention to finding out the internal relationship between each part, from the surface to the inside, from the shallow to the deep, from the phenomenon to the essence.

Accuracy of language: the expression of time, space, quantity, scope, degree, character, nature, procedure, etc., all require accuracy. The language is concise and the explanations are rigorous.

The center of the expository essay is clear and prominent, the essay is scientific, organized, and the language is precise and vivid. It illustrates the characteristics, essence, and regularity of things by revealing concepts. Expository essays generally introduce the shape, structure, category, relationship, and function of things, and explain the principles, meanings, characteristics, and evolution of things.

Expository essays are very practical, and they include advertisements, instructions, synopses, tips, rules, bylaws, explanations, etc. Some expository texts are chronological, some are spatially ordered; Some are written from phenomena to essence, and some are written from primary to secondary; Some are explained in the order of the technological process, and some are explained in the order of the nature, function, and principle of things.

What is expository writing: Expository writing is a style of writing that uses explanation as the main expression to introduce and explain things and facts;

The three elements of an expository essay: 1the characteristics of the object being described;

2.the order in which the descriptions are made;

3.Illustrate the method.

Features of the expository text:1scientific content;

2.structurally organized;

3.Accuracy of language.

Ha ha! It's an abbreviation, just make do with it

1. Three elements.

Scientific nature of the content:

Truthfully reflect objective things, grasp the characteristics, essence and laws of things, and give readers a correct understanding.

Organized Instructions:

Writing chronologically is similar to a narrative; Write in spatial order to pay attention to the observation points, pay attention to the position and direction of the surface and the inside, the size, up and down, front and back, left and right, southeast and northwest, etc.; When writing in a logical order, we should pay attention to finding out the internal relationship between each part, from the surface to the inside, from the shallow to the deep, from the phenomenon to the essence.

Accuracy of language.

The representation of time, space, quantity, scope, degree, characteristics, nature, procedure, etc., all require accuracy. The language is concise and the explanations are rigorous.

2. Examples. 1) As you know, our life is inseparable from the light and heat given by the sun, and the sun can also provide normal heating for human beings for another 4 billion years, and after 4 billion years, the sun will continue to expand until it engulfs the earth. And the sun has no problem providing heat to the earth for 40 million years, because these 40 million years provide less than 1% of the sun's total heat. So, one can set 40 million years as a time goal to live on Earth.

2) If the industrial revolution 200 years ago was a qualitative leap in human science and technology, then the natural resources consumed in these 200 years were n times the total amount of resources consumed in the previous 4 million years. Industry, agriculture, life, everywhere is waste, everywhere is destruction. If we continue in this direction, within 400 years, the earth will be unrecognizable.

column numbers).

One: Describe the object.

2. Explain the method.

Three: Explain the order.

It's all here, and there's all the essays.

1. Find out the object of the explanation.

To read an article, in order to accurately grasp the object of explanation, it is necessary to analyze it from two aspects, one is to look at what the article explains from the whole, and the other is to look at which aspect of the thing is explained from the part, that is, the specific object of the article.

2. Grasp the characteristics of the object.

In order to accurately understand the content of the expository text, it is not enough to find the object of the explanation, but also to accurately grasp the characteristics of the object of explanation. The key to whether an expository essay achieves the purpose of explanation lies in whether it explains the characteristics of things.

3. Clarify the order of explanations.

The expository essay should have a clear and reasonable structure, which is the order of explanation. There are generally three types of explanation order, namely spatial order, temporal order, and logical order. When reading an article or passage, pay attention to these three aspects.

The spatial order is generally from top to bottom, from left to right, from front to back, from far to near, first middle and then both sides. The chronological order is generally from ancient to modern, from the past to the present, and so on.

The logical order is from phenomenon to essence, from cause to effect, from major to secondary, from characteristic to use, from whole to part, from general to particular, from general to concrete, from known to unknown, from surface to inside, and from this and there.

4. Master the method of explanation.

Common illustration methods include examples, comparisons, numbers, categories, analogies, definitions, interpretations, quotations, charts, etc.

5. Understand the structure of the description.

There are four common structural relationships in expository texts.

1) Juxtaposition: The relationship between the levels is equal and juxtaposed.

2) Progressive: The following instructions are further explanations on the basis of the previous ones. The relationship between the various levels is from shallow to deep, from the surface to the inside, and the layers are deep.

3) Total fraction: This structural form can be derived from three cases, namely total fraction, total fraction and total fraction.

4) Contrast: After the central argument is proposed, the central argument is demonstrated from both positive and negative aspects. The purpose of using the contrast formula is to highlight the correctness of one of the aspects through the comparison of the two aspects, and the other aspect only plays the role of foil and foil.

The easiest way is to write about an object first, and write about its appearance and specific functions.

After reading the text, it's about how much you can say, and it's about what you're trying to say. It's simple
