I urgently need an expository essay on the scenery in the second year of junior high school

The main role of scene description has four aspects.

In the second year of junior high school Chinese composition, the description of scenery is a very important part. As a learner, you should master the writing skills of this section.

We need to clearly understand the purpose of scene description: to let readers feel the whole scene to give people visual, hail, auditory, smelly, tactile and other feelings, so that the scene is more real and vivid. Don't limit yourself to one aspect, but describe it all.

For example, in an autumn park, in addition to the fallen leaves, there are also the shape and color of the trees, the sound of the leaves blowing in the wind, the smell of the breeze, and the feeling of walking on the fallen leaves.

We need to pay attention to the structure of the sentence and use modifiers and figures of speech wisely to make the essay more expressive. For example: use adjectives and adverbs to describe the scene; Use ranking ratios to make the article more rhythmic; Use figures of speech such as metaphor and personification to give readers a deeper understanding of the scene described.

In the composition, it is necessary to pay attention not only to the description of the scenery, but also to the description of emotions. For example, describing a piece of grass can express one's own expansive and open-minded emotions; Describing a stream can express one's deep, clear thoughts, etc.

If you want to write a good composition on the description of scenery, you need to read and practice more, and improve your observation and expression skills. Using more advanced vocabulary, sentence structures, and figures of speech can make your essay more exciting. Pay attention to the layout and word count limit, segment it reasonably, don't appear too long paragraphs, and don't write too much content, so as not to affect the quality and score of the article.

The earth is the only home of human beings, and in the vast universe, in addition to the earth, no other planet suitable for human existence has been found at present. The earth is the only home for us human beings. In this homeland, man is the master of the earth.

In addition to us humans, there are many living substances, such as flowers and trees, insects, fish, birds and beasts. These creatures live in the same environment as us and together make up this big family. Water is the source of life, and human life is inseparable from water.

The human body contains about 65% of body weight, and if the body loses more than 10% of its water, it can lead to death. Air is a necessary condition for human survival, and people breathe air all the time. Oxygen** is used in the photosynthesis of plants, and all kinds of plants are oxygen processing plants.

If there were no plants on earth, we humans and other life would cease to exist. Wildlife depends on plants and can also protect them. Take birds as an example, 90% of birds feed on insect attacks, and many beneficial birds are the guardians of crops and trees, and are natural enemies of pests.

100 tree insects can eat the leaves of a large pine tree in ten days, while a pair of large can eat more than 400 insects a day. Without these beneficial birds, pests would be infested. On Earth, human plants and animals are actually one and the same"Biosphere"、"Circle of friends", no one can do without anyone.

The reason why human beings can survive on the earth is because of ecological balance. The earth provides us humans and all forms of life with a life support system – air, water, proper light and heat, and energy, among others. In fact, this pristine ecological balance is extremely rare on a global scale, and we may only see it today in places where humans have not set foot in it.

While the natural environment provides environmental resources for human survival and development, it has been destroyed by human machines. The prospects for humanity are optimistic only when the natural environment is in harmony with an ecological balance. So, please protect the environment and be kind to your home, only in this way can we make our home a better place.
