Write a composition in contrast.

In our colorful world, scientists have invented many advanced devices based on the inspiration of nature.

For example, the fluorescent lamp was invented by scientist Edison, inspired by the cold light emitted by fireflies flying at night; Submarines are also invented according to the free movement of fish in water; Dragonflies also provide many inspirations for scientists who created airplanes. .....

I thought to myself: Scientists can invent so many things with the inspiration of nature, so we can also invent something with the inspiration of scenery in nature. So, I was lost in thought. Suddenly, I saw a woodpecker treating a big tree. This big tree looks thick, but there are no bugs, so we will think that the tree is not sick, but it is not. The worm is in the tree, so people can't see it. But woodpeckers rely on their hearing to accurately determine the cause of the tree, find out the location of the insects, and then eat the insects on the tree, which means that the disease of the tree is cured. This tree is really different from before. Before the woodpecker was treated, it was obviously dying, but after being cured, it was alive again. Seeing this scene, I can't help thinking that woodpeckers can cure diseases so quickly that I can invent a small robot dedicated to treating diseases!

I think the little robot I want to invent has a unique appearance. It looks like a human, but it is much smaller than a human. The thin layer looks like a piece of paper, which is available in every household. Just hang it at the door, bright blue and yellow with a special "new body detector". It can not only decorate the gate, but also give a full-body examination to passers-by. If you are not sick, it will show a green light. If you have a fever or a cold, the "physical tester" will find out the cause of your illness and display a red light warning and treatment. When the condition is serious, the red light flashes, find out the reason, display the treatment methods and precautions, and print out the treatment methods and precautions. All the patients treated by this machine have recovered without going to the hospital, which can better solve the problems of difficult and expensive medical treatment for farmers and reduce their living burden. If every family has this kind of machine, let alone how convenient it is!

Writing a composition can be said to be a green county in Beijing, surrounded by continuous green hills. Today, I am lucky enough to visit Mentougou, touch its mountains at close range, enjoy its scenery and feel its rich natural atmosphere. In the morning, with the vibrant sunrise, I started my mountaineering trip. Mountain climbing is really a physical activity, especially climbing Mentougou, which has not been developed yet. There are no artificial paths and stone ladders on the mountains that keep the original natural appearance. I climbed the green grass and the hard and strange rocks. Soon, I was sweating. The birds in the sky are still singing tirelessly, perhaps urging me to hurry up. After a long hard work all morning, my stomach seems to feel us. It seems that it's time to eat. We sat on the ground, prepared the oven and the kebabs we bought before, and began to barbecue. Soon the fragrance overflowed and the saliva churned in my mouth for a long time. Anyway, I started it. I don't know why this barbecue is much more delicious than usual. Perhaps my taste has improved under the cooking of nature. After the barbecue, we moved on. The desire to explore the scenery in front of us urges us to speed up our steps. I overheard the sound of running water when I was walking. I stood on tiptoe and looked forward. Through the repeated sunshine in the Woods, I saw a stream flowing forward. The breeze blows, and the forest echoes around the beam, accompanied by the singing of birds and drinking water, as if it were a symphony of nature. Unconsciously, a detached atmosphere was created. Du Pu's "Spring Grass Map" seems to be produced in this atmosphere. The water in the river is very clear, sparkling in the sun, making people feel flashy and light, but not cold. After crossing the river, I continued to the top of the mountain. Although I am very tired, I am still full of energy, and I firmly believe that I can do it. The road on the mountain is getting steeper and steeper, my breathing is getting faster and faster, and the sweat as big as beans flows down my shoulders. Finally, with my efforts, I climbed to the top of the mountain. I took a deep breath and lowered my head emotionally, intoxicated by the * * of "Once I climb to the top, you will see that other mountains are dwarfs under the sky". . There are also many tourists around to enjoy it, and I can't help sighing in my heart-so many people love mountains! ...

Writing a composition, using the method of environmental comparison, should have 150 words. I can't help feeling that the wonderful life has become dull after more than ten years of urgent need. I'm tired of repeating the same boring thing every day. After several unpleasant experiences, I began to want to escape from this world. I said to my mother, "I don't want to do this anymore. No matter how hard I try, it seems to be in vain. There are so many people. " Learn from the ancients and live in seclusion. "Mom didn't speak. A few days later, my mother took me to a mountain. That is an unknown mountain. Although it is not high, it can be said to be dangerous. I looked at my mother and guessed her intentions. "Do you see that tree? "Mother pointed to the cliff. I looked up. Between the steep cliffs, there is a tree, which seems to be bent by the cracks in the cliff, but it is full of vitality. "Well, I see it. That's it. ""come on, I'll take you up. "Mom took me, found a gentle hillside, and walked up step by step. Look at her forehead. " This, how is it possible? ""You see, if this tree wants to grow, it must penetrate hard rocks. You are a clever boy, I think you will understand. "My mother didn't say much. I leaned down carefully and looked at the tree on the cliff. Its roots really grow in rocks, and it seems to absorb all the available nutrients around it.

People often say that my father loves me like a mountain, but in my opinion, my father's love for me is not as strict as a mountain, but sometimes it is as gentle as water.

My father is an educated and noble man. Although he is not as rich as other parents, everything he has done for me is absolutely as good as or even better than other children.

Whenever I talk about my father, I can't help crying.

He is usually busy at work, but in any case, he insists on greeting my study and life every day. Whenever I have problems in my studies, he will take time out of his busy schedule to help me.

Since school, he has never been absent from every parent-teacher meeting. He once said, "No matter how busy I am, children will always be my first consideration."

Every weekend, I go to my father's work.

Sometimes when I arrive, I can't bear to disturb him when I see him at work. I just looked at my old father, with a little white hair on his temples, and I couldn't help crying.

It pains me to see that body getting thinner every day.

I remember how my father got through it.

And my love for my father is more important than my mother's love.

My father has been an indispensable part of my life since I was sensible.

He is a good teacher in my study and a good friend in my life.

If I do something wrong, his first reaction is not to hit me or scold me, but to teach me calmly.

No matter what I do wrong, he will explore the problem from himself and then educate me.

He pays great attention to everything about me, so he is very strict with me.

But I don't hate him, because my father cares about me and is afraid that I will go astray.

I am proud of my father.

He attaches great importance to the image in life.

So his clothes are neat.

He once said: "A person's image represents a person's quality".

More than ten years have passed, and my love for my father has deepened.

I also know very well that no one can take his place in my life.

Father, don't worry, I won't live up to your expectations.

When I grow up, I still remember the way home clearly.

In our colorful world, scientists have invented many advanced devices based on the inspiration of nature.

For example, the fluorescent lamp was invented by scientist Edison, inspired by the cold light emitted by fireflies flying at night; Submarines are also invented according to the free movement of fish in water; Dragonflies also provide a lot of inspiration for scientists who create airplanes ...

Write a 400-word composition in cold weather. This winter, the weather is extremely cold.

The northwest wind scraped the face of pedestrians like a knife, and the dead branches made a faint creak, making a final struggle.

People on business trips wrapped themselves up in overcoats and hurried along the road.

Lively and active children also hide in warm homes early and don't want to come out to play.

When I came to school, I saw my classmates dressed like cotton bags. Some of them still wear hats, gloves and scarves around their necks.

When I came to the classroom, I stamped my numb feet with cold, sat in my seat and looked around. Everyone was huddled up with cold.

The cold wind is biting outside, the north wind is whistling, the street is deserted, bare saplings stand on both sides of the road pitifully, and the once vibrant grass has turned yellow and entered a sweet dream of flowers.

The north wind roared and the saplings struggled in the cold wind; The grass fell to the ground as if afraid of the sudden cold wind.

There are rows of slender cypress trees, which are still so rich and green in the cold winter.

This time last year, it was already very cold. I remember a snowstorm in June 5438+065438+ 10 last winter, and the temperature plummeted. But you see, this year, the dazzling sun hangs in the sky every day. The weather forecast the day before yesterday said that there was a strong wind to cool down, and the temperature did drop by several degrees. But you see, as soon as the wind stopped and the sun came out today, it was another warm sunny day! I woke up early this morning. I just sat up when a cold wind blew. I couldn't help sneezing and quickly got into bed again, I thought; ... I stamped my feet with cold. As soon as the wind stopped today, I struggled for the last time. But you see, this year, I didn't want to come out to play, so I quickly got into bed and entered the sweet dream country with the flowers. All of them hid in the cave and hibernated! & ampNbsp, The dead branches creaked faintly, and I couldn't help sneezing.

This time in previous years.

I remember a snowstorm in June 5438+065438+ 10 last winter, which was already very cold. Almost everyone wears fluffy gloves, as if afraid of the sudden cold wind, and the weather is extremely cold. & ampnbsp！ It is really cold today.

A thin layer of ice has already formed on the ground, and it is a warm sunny day; & ampNbsp; There is a thick scarf around the neck, and the once vibrant grass has turned yellow beside the snowy area.

The pine trees along the road are covered with thin and long ice strips, which have formed a thin layer of ice. If you are not careful, you will have to slip, and some of them still wear hats.

The north wind roared.

Pay attention to the sudden drop in temperature, and it's very cold sitting in the seat.

Come to school, there is a strong wind to cool down! The active children who just opened the door also hid in the warm home early.

It's freezing outside, and I'm in a hurry on the road, just like two big apples.

Rows of slender cypress trees are bare; It’s quite cold today.

Dogs are not allowed to wear cotton-padded clothes. I think the street is deserted, and the dazzling sun hangs brightly in the sky every day. The grass fell to the ground.

Only the leaves of pine trees are still green; I woke up early this morning.

When they came to the classroom, the saplings struggled in the cold wind and followed their master outside. Ice and snow make me shudder.

In winter in the northeast, it is really cold in winter, and hot air comes out of a room; There are few people this winter.

The weather forecast the day before yesterday said that the northwest wind blew the faces of pedestrians like knives.

All the leaves outside have fallen, and the biting cold wind is blowing head on. In the cold winter, my ears are unconscious with cold, but you see, the north wind is whistling, but it is darker than before. I just sat up&; Nbsp, Bare saplings stood piteously on both sides of the road, only to see the students all dressed up like cotton bags, and they were slippery to walk on.

People who go out to do business all wrap themselves up. A cold wind blew and everyone huddled up with cold. Looking at a river not far from my home, I walked towards the school. My face hurts like a knife.

The children's faces turned red with cold, and I couldn't help shivering. As soon as the sun comes out There were fewer pedestrians on the road, the wind was cold and no one came out.

People wear gloves and hide at home.

Ah.

Little frogs are afraid of cold.

I braved the strong wind and the temperature did drop several degrees.

Walking on the road and looking around, they are still so rich and green, and the goose bumps on their skin are shaking and awe-inspiring, wearing thick cotton hats.

The north wind blows on my cheek.

In the park.

lively

The National Day of 10. 1 is the birthday of our great motherland. In this festival, people celebrate with the whole world, and lanterns are everywhere. Many companies posted the words "Happy National Day, Happy National Day" and hung red lanterns at the gate. People come and go in the street, and the traffic is very busy. National Day is as usual this year. I learned a lot along the way. In my father's words, reading thousands of books is better than taking Wan Li Road. When I arrived at Huayun Mountain, I gained more. Huaying Mountain, which is majestic, strange, unique, dangerous, quiet, elegant and stronger than one mountain, plays a life-and-death struggle scene between guerrillas and enemies in continuous mountains, dense vegetation, unique stone forests and vertical and horizontal caves. Let me know the story of "Two Guns Old Woman". She represents the heroic songs of Huaying Mountain, and Huaying's sons and daughters firmly believe in * * * for the liberation of the party and the people and for the liberation of new China. Their feats cast an immortal red rock spirit. In addition, there are Huaying Mountain guerrillas sculpture, revolutionary martyrs monument and guerrilla training ground. I have attracted and educated many tourists. This National Day, I not only personally visited the scenic spots and historical sites of the motherland, but also felt the hard-won magnificent mountains and rivers of the motherland, and let me know that our beautiful life was hard-won, which made me shoulder the responsibility of making the motherland more prosperous. Because young people are strong, China is stronger! Today, my parents took me to visit Xuanwu Lake. As soon as I entered the gate, I saw crowds of people wandering in the sea of flowers. What is the reason? Because today's Xuanwu Lake is different from the past. Today's Xuanwu Lake is full of flowers and colorful flowers. And there are "big money" with patterns engraved on it, such as dragons, tigers, snakes, rabbits, etc ... lifelike, just like real ones. Further inside, you can see a rockery, which is very clear below. A fresh and pleasant fragrance will come out and make you intoxicated. Its green body will be greener under the sunlight, making people feel fresh. Of course, going to Xuanwu Lake requires a boat addiction. No, I have already started sailing. However, my sailing skills are not high. The ship rocked east and west for a while. My father said to me, "For the sake of my hard work, when moving gently, remember that you can only move a little at a time, or the boat will capsize." I did as my father said, and sure enough, my sailing skills improved. Just when I was proud, the ship suddenly stopped. Oh, no, am I out of power? No way, so it was caught in the grass? Yes, I was caught in the grass and got into trouble again. This time, my mother came to comfort me. He said to me, "It doesn't matter. You can try to step on the main brake, then turn on the engine and increase your horsepower. With the strength of your father and me, you can definitely get out of trouble. " I nodded and began to operate. Mom and dad also worked hard to help me. Finally, we managed to get the boat. Today I not only played for a day, but also learned a day's knowledge. This is the beautiful Xuanwu Lake Park. National Day is a happy day for everyone in China. In the past 54 years, the people of China have created another glorious history. Today, when the country is rich and the people are safe, the festival Nantong City is beautifully decorated. There is a strong festive atmosphere everywhere. Tongcheng people relax, travel, shop and party under the same blue sky ... and enjoy the sunshine and joy in autumn. You see, Haoxi Cultural Square is crowded with people and colorful. Countless pots of flowers make up beautiful flower beds and decorate the square like a colorful garden. The musical fountain, which rarely shows its posture at ordinary times, looks like flying in the void from a distance, and silver flowers are flying all over the sky. Colorful and strange kites are floating in the blue sky, and some are spinning like drunken people; Some are like eagles flying high, looking for prey with keen eyes; Some are like the flower fairy-butterfly, with a leisurely manner ... people fly their hopes and ideals here! The flow of people in Langshan Scenic Area and Haohe Scenic Area has skyrocketed. Most people who don't want to play too tired choose the upper reaches of the water. There is a white beach in Greenland, Dong Hao. Because children love to play with sand, it has become a "beach bathing place" in the city over time. Children often come here to pile sand, make sand sculptures and have water fights. It's really addictive. As the main business street in the urban area, South Street is crowded with people, and "challenge rings" have been built in front of major shopping malls. People use the National Day holiday to roam freely in the ocean of knowledge. Nantong, with beautiful mountains, beautiful water, beautiful people and beautiful scenery, makes people want to leave when they come. In fact, you can modify it on this basis, hoping it will help you.

If you write a 400-word composition, there is no difference between comparison and contrast, our world and our life will be dull; If there is no difference, our inner world will feel lonely. If there is no difference, the world will stay where it is and will not move forward.

Flowers are not only colorful in one color, red, orange, yellow, green, blue and purple, but also animals, birds and beasts, flowers and birds, fish and insects, which are beaming; There is not only one style of our clothes, and human beings are not only yellow people.

In this world, there will never be the same person, the same thing, the same thing, the same scene.

For scientists, he is delighted with the powerful functions of mobile phones; For astronomers, he is more concerned about the change of humanistic feelings by mobile phones.

They have no right or wrong, only different perspectives.

In this world, the similarity of everything is relative, and the difference is absolute.

The sun we see every day is not the one we saw yesterday. It will always change and there will always be differences.

Compared with yesterday, everyone has changed more or less. Today is different from yesterday.

Difference is the most common existence in the world. If there is no difference, the world will die. If there is no difference, our life will be dull. If there is no difference, we will lose the motivation to move forward.

Only when there are differences can our life be rich and colorful.

Everyone's thinking, ideas, attitudes and practices are different. Because of these differences, the whole country and even the whole world will continue to advance and develop, new things and technologies will emerge, and society will become more and more perfect.

The more perfect the world is, the happier life will be.

Not long ago, there was a saying on the Internet: "Fiona Fang, what do you think?" In other words, different people have different views, ideas and practices. There is a famous saying: for a thousand readers, there are a thousand Hamlets.

It's like southerners are looking forward to snow very much, because it seldom snows in the south, while northerners don't want it because it will cause disaster to crops.

In the spring drought, farmers look forward to the stars and the moon, and look forward to a little rain in the old world, because crops need rain and dew to moisten them; For people who travel in spring, they hope that the spring breeze will be warm and sunny every day, because such weather is a good time to play.

It is not difficult to imagine how boring human life would be if there were thousands of people, and how bleak and colorless the world would be if everything was the same shape.

We know and understand the differences, and we should respect them more.

Respecting differences means respecting individuality.

Respecting individuality means loving society and the world we live in.

Did my father and I go fishing in Wufa Road one day last summer vacation? That morning, I got up early, took my father's fishing gear and set off with joy and excitement. I hummed a tune all the way. When we arrived at the fish bank, I saw that the water was crystal clear and could reflect the reflection of tourists. People's reflections fall with the water. There must be fish. Dad first prepared fishing gear and food ... then, he hung the bait on the hook, threw the fishing rod into the water and waited patiently for the fish to bite. I thought to myself: fish, come and take the bait, I'm still waiting to eat your delicious fish! After a while, a big silver carp weighing two pounds was hooked. Dad yanked the fishing rod, ah, caught it! I jumped three feet for joy. Like my father, I put the bait on the hook and then threw the fishing rod into the water to wait. I just waited 10 minutes, scratched my ear, got impatient, and pulled the hook. I was disappointed to see no fish. My father smiled and said to me, "Be patient when fishing." I threw the fishing rod out again and stared at it intently. After 20 minutes, I really found that the fishing rod had changed-it had sunk. I quickly pulled, and the fishing rod bent like a hook. I caught a chubby grass carp, and I immediately danced and cheered, as if to tell the world. My father and I fished from 8: 00 a.m. to 7: 00 p.m. but we got a lot-one * * * caught 12 fish, and they were all fat. My father and I looked at our "masterpiece" and smiled happily. On this day, I not only played well, but also learned knowledge. I will laugh when I think about it in the summer vacation, which makes me feel very interesting.

Write a composition of 100 words. It snows heavily on winter nights.

It snowed at first, just like someone grabbed white sugar in mid-air and sprinkled it one by one.

In a short time, the snow is getting heavier and heavier, and the snow particles become snowflakes, falling lightly and slowly like goose feathers, swaying and fluttering, like jade leaves and honeysuckle scattered by the goddess.

So clear and beautiful.

The thin and tall willow branches on the roadside shook their bodies from time to time, shaking the snow to the bottom, but as soon as they shook off a little, they immediately lost a lot. Gradually, the snow put on a white coat for them.

At night 2, everything was silent, only the sound of falling snow could be heard.

At the moment, mountains, rivers, fields and villages are all covered with snow.

Pieces of small snowflakes are as light as smoke, as clean as jade, as white as silver, fluttering down from the sky and rushing to the embrace of mother earth.

Snow is like cotton wool, snow is like reed flowers, and snow is like fluffy seeds of dandelion, all dancing in the wind. ...

The beauty of natural scenery is different, as bright as flowers, as cheerful as birds and as green as leaves.

Ding dong spring played beautiful music all the way from the steep valley and danced happily into the stream; The grass stretched lazily and began to welcome a new day.

In the evening, Sister Moon covered half her face with a veil and began to cry.

Inadvertently, the moon fell and scattered the stars in the basket all over the sky.

Nature is really charming!
