The sun shines on the earth, how beautiful the world is! The streets and alleys are clean and bright, with lush trees and flowers, which makes people feel relaxed and happy. When dark clouds covered the sun, the world became dim, birds disappeared, songs stopped, and flowers hung their heads.

The sun is the source of light and heat and the source of our life. If there were no sun, there would be no flowers, trees and insects, and there would be no life on the earth.

It belongs to all of us and to the children. Children need sunshine. With sunshine, they can grow up, enjoy the opportunity of life and understand the laws of nature. Man's wisdom is passed down from generation to generation by the sun.

However, some evil people want to steal the sun.

There are two kinds of dark clouds that can cover the sun. A cloud can bring life-giving drizzle and crystal snowflakes to the world, and there is no harm in such a cloud temporarily covering the sun. Everything on the earth needs not only light and heat, but also water to grow and bloom. Dark clouds can give water to the earth, and sunshine will give us a kind smile and smile at a clean and fresh world.

But there is another kind of cloud that can cover the sun forever. These dark clouds are terrible and destructive. They are like giant mushroom clouds. This kind of cloud will steal our sun forever one day. Such clouds will not only steal the sun, but also take away life. They will destroy all life on this beautiful planet.

We will never allow these terrible dark clouds to steal our sun. The sun is life. It belongs to all of us and no one can steal it. The sun belongs to children. May it shine on all of us forever and make the earth shine like gold forever!

Today is cloudy, so is my mood. In class, I open the paper with a nervous heart. The paper was covered with crosses, and the score broke my lowest record. I shook my head with a wry smile. The score was as expected.

Self-study class, shall I take that out? Terrible? Paper, began to change the subject. Look at those wrong questions. I really want to laugh, laugh that I am not serious and laugh that I am confused. In anger, I looked at the law and the circuit diagram, stuffed the paper into the desk and sat in front of it.

Look out the window. Hey! What about the sun? Say to yourself, yes! Today is cloudy, how can there be a sun? The dark clouds outside the window, like snails, creep slowly in the sky, forming strange patterns. I like these patterns on my desk.

The clouds passed, the sun appeared, the wind dispersed the clouds, and the light penetrated the clouds. ? Ah! The sun is out again? Looking at the sun shining again after the clouds. I'm glad, I'm happy, and I can't help thinking of myself. Repeated setbacks left my heart scarred, but I survived. Why can't I stand it this time? I asked myself, can't I get through this time? No? A voice rang in my heart. Maybe setbacks will make your heart scarred, but look at the sun outside the window. It is covered by clouds again and again, but it never sets. ?

? Frustration makes your heart scarred, but don't forget that these scars are the commemoration of success and the spoils of your victory after challenging all difficulties. Don't give up, its test will make you stronger and you will learn to be patient. It brings you closer to success. ?

The sun went down, I smiled at Xia Hong, and I knew it would rise again tomorrow!

Sun and I are close friends. I slept at home in primary school and didn't want to get up in the morning. At this moment, the sun shines on my bed, so bright. The sun seemed to say, good friend, it's time to get up, so I got out of bed, and it seemed very satisfied. ?

I am on my way to school, and the sun will accompany me to school. When I get home at night, the sun always shines weakly on my windowsill, hoping to let me study and review for a while, so my academic performance has improved rapidly. I really appreciate my good friend.

But good friends sometimes have contradictions.

Once, in summer, the teacher will hold a quiz. I also want to know how much knowledge I have mastered during this time, so I do it seriously. The sun is like an invigilator sitting in the sky, watching us take exams. But just as I was doing my best, the sun

According to the sharp rise of the earth's temperature, the students can't stand it. The teacher had to say no to the exam. I'm disappointed. I don't know how much knowledge I have learned during this time. I looked up in anger and angrily accused the sun. The sun knew his mistake and covered his face with a cloud.

Going home from school, still angry at the sun's fault. But who knows that the sun has entered my room with a faint light, as if to explain the mistake just now. He also said that the next exam will definitely give us a sunny, lukewarm weather. I was so happy that I forgave my good friend, and I decided not to be angry with my friend anymore.

At this time, my good friend said goodbye happily and hid down the mountain. The sun and I will always be inseparable friends.

The sun is a celestial body that can emit light and heat by itself, and its volume must be 130 earths to match a sun. There are raging fires inside and outside the sun, with flames as high as tens of thousands to hundreds of thousands of kilometers. It is far from the earth, about 1. 500 million kilometers.

The teacher told us to do the experiment. First, we take out a piece of tissue paper and put a magnifying glass on it. A golden dot will appear on the paper. Gradually, gradually, the paper will be slowly burned by the sun. Why? It turns out that the heat of the sun is very high, and its surface temperature is as high as150,000℃, and even steel will turn into a pile of steam when it touches it. The sunlight is so strong and dazzling that it is invisible to the naked eye. Its light makes people unable to open their eyes, and sometimes even leads to blindness when facing each other. However, the light on our earth is what it brings us. Without the sun, there would be no light. Even the light of the moon comes from the sun. In fact, the true face of the moon is just a non-luminous uneven sphere. At night, we see it so bright because it reflects sunlight.

The light and heat emitted by the sun are a kind of energy, which we all call solar energy. Solar energy can dry clothes, wet clothes are easier to dry, and solar energy can prevent quilt clothes from becoming moldy. She can also dry food and salt. The sun contains a lot of energy, and the energy emitted per second is equivalent to 65.438+0 billion times of the total energy consumed by people on the earth now. Solar energy is inexhaustible, clean and pollution-free, and has many functions. Solar energy provides indispensable light and heat for the survival of plants, animals and humans. If there is no solar energy, there will be no life on the earth, and there will be no good life.

The sun tomorrow.

The life span of the sun is several billion years. People have written fairy tales for you. Is what people long for.

Whenever I get up in the morning, I always hope that today is a sunny day. The sun! The sun! You can bring happiness and joy to many people, but you are also wrong. In the arid and wide desert, instead of thinking about their difficulty of having no water to drink, you should bask in them and punish them. Did they do something wrong? In anyone's heart, your position will be different.

When it rains, the rain douses the heat in your heart. Isn't it your sun? Play with people at will. In this way, we began to hate you, hate you heartless.

Everybody, resist! Just set up a factory to resist the sun. Now this abnormal climate is all thanks to it. Normal March is about 15 degrees, but he! But he raised the temperature by more than ten degrees. It's so hot here. :? Since it is so kind to us, it resists and destroys its lovely earth so that it can't laugh! ?

The sun! Oh, my God! Do you hate us so much? Are you going to sun us into dried meat? All this is meaningless! Let's all lay down our weapons and fight each other. Such meaningless struggle will only make us all miserable.

People, compatriots! In this environment, don't fight against nature! Drop your weapon and surrender! Close all factories. Let nature give us a better life!

That's it.

Will bring a better life to tomorrow, and tomorrow's sun will be brighter and more beautiful!
