1. How to write a 600-word composition in the micro world?

Yuting Wu Tao Zhuang Primary School Class 6 (2)

Desire is a ray of sunshine, shining deep in the soul; Wish is a sailboat, sailing in the boundless sea; My wish is a paper crane, flying far away with my wish! My wish is to witness the World Expo with my own eyes! An accidental opportunity brought me closer to the Expo and my wish. ...

On this day, I embarked on a dream-seeking journey.

Blowing the slow spring breeze, watching the magnificent scenery. After two hours of turbulence, we finally arrived at the high-profile World Expo. Here, we walked around the maze-like passage, passed the "annoying" complicated security check, and finally entered the long-awaited Expo Park! "Wow, it's beautiful. It won't be a mirage, will it? " Accompanied by praise, the Expo tour began!

The first pavilion you see is the USA Pavilion, which looks like an eagle with its wings spread. Welcome guests from afar! There are also roof gardens and waterfalls, which add a bit of mystery to the exhibition hall! Everyone can't help but exclaim, "Hey, the fun is yet to come!" A male student pointed to the Danish Pavilion "far away" behind him. "Let's go there next!" In this way, our next destination is the Danish Pavilion.

With a brisk pace, the Danish Pavilion came into view. Really worthy of the phrase "happy life, fairy tale paradise"! The design of the Danish Pavilion consists of two circular tracks. The white curtain wall gives the exhibition hall a symbolic marine temperament, which embodies Denmark's long marine tradition. Seen from the top, the Danish Pavilion is like a spiral body, surpassing the traditional exhibition form. What a refreshing experience!

……

"After walking so much, everyone is tired. Let's get something to eat first, and then we will sprint to the last China Pavilion! " The teacher hoarse voice doing the final "struggle"!

Looking at the "magma-like" hot land erupting everywhere, we set off again and got on the bus to China Pavilion. "Better city, better life is the theme of the Expo and our common dream. Each exhibition hall has its own characteristics, and they show the world a different world. But the most worth mentioning is undoubtedly our China Pavilion! " The teacher told us with relish.

After getting off the bus, we followed our teacher to the long-awaited China Pavilion. As soon as we saw its appearance, we couldn't help but be deeply impressed by its grandeur: the bright red facade, the design of the inverted tower and the decoration of porcelain patterns are really magnificent, just like a towering crown! The exterior is so outstanding, the interior must be magnificent! Look:/kloc-The 0/00-meter-long city wall is covered with the famous Song Dynasty painting "The Riverside Scene at Qingming Festival". Seal script constitutes 24 solar terms for the wall; On the verge of extinction, the folk art of "Three Axes" reappeared ... Along the way, we laughed and let go of pure joy and excitement!

Unconsciously, time flies like a blink of an eye! But we are still happy, because visiting the World Expo is the pride of China people, the wish of generations of China people, and everyone's vision and hope for a better life! We can proudly shout: I'm from China!

2. Write a 600-word composition of animals in the micro-world. In the early morning, somewhere on the grassland, thousands of small creatures are moving ... some insects (ants) are running around on the grassland. Perhaps, this drop of water also represents a flood, a stone is also a mountain, and small trees and grass flowers are equal to big trees.

Ants also carry their own food. Although we picked melon seeds, it was a piece of cake for Zhang Fei to eat bean sprouts, but the ants felt exhausted, but they still stubbornly moved their food.

In another place, another group of life-(bees) is also tenacious. Early in the morning, they flew over the grassland early in the morning, found a place with many flowers and began to collect honey. Who are they really working for?

It was already afternoon after picking honey, and they flew home again. In the evening, the forest cleaner (dung beetle) came.

They struggled to push the dung ball home. Sometimes, a small thorn is a setback. The dung ball was stuck by thorns, and the dung beetle pushed it left and right, but the dung ball still didn't move.

Although the dung ball was stuck, dung beetles pushed it tenaciously, and dung beetles's persistent spirit is worth learning. Although bugs are small, they are also life, and there are always some people who turn a blind eye to these lives.

3. Write a "scaled-down" story about what happened to you in the micro-world. How can I write a good composition? You should write it yourself. Always thinking about plagiarism is not good.

Seeing that you have no idea, I recommend an example for your reference only.

Theme: Entering the Insect World

One night, I fantasized that I had become an insect and came to their world-the microscopic world.

As I walked forward, I suddenly saw a huge figure-a beetle, pushing cow dung forward. This cow dung seems to be beetle food. The beetle pushed forward, but suddenly the cow dung stuck into a branch, and the beetle couldn't push any more. It changed the direction of pushing, pushing the cow dung, and the cow dung turned. After a while, the cow dung was finally liberated, and the beetle continued to push forward until it reached its home, and then buried the cow dung. The beetle seems very happy!

I walked on and saw thousands of ants working. Suddenly a pheasant flew by. It eats ants one by one with its sharp mouth. Many ants climbed onto the pheasant's foot and bit it hard, but it didn't seem to hurt at all. The pheasant ignored them and continued to eat the ants on the ground with relish. I'm worried about their safety. The ant climbed onto the pheasant's stomach again and took a bite. Pheasants can't stand it. It stopped eating ants on the ground and fanned the ants on its stomach with its wings. They ran away at once, and so did the pheasant, losing all their feathers when they flew away. I smiled and smiled for their brave spirit.

I continued to check and saw two beetles fighting for territory. One beetle invaded another beetle's territory. The beetle said, "You didn't buy this place. Why are you the only one here? " I named one beetle Potter, and the other beetle bit people. The Potter beetle immediately rushed to the beetle bit, and the beetle bit rushed to it. The two are equal. Potter the beetle suddenly stabbed the beetle bit with his hidden weapon, and the beetle bit fell off at once. Porter the Beetle said, "Whoever occupies my territory will die."

I'm surprised that there is so much hatred in the insect world that they still fight with each other. The insect world is similar to the human world. If there were less hatred in the human world, the world would be a better place.

4. Micro-world The micro-world in my eyes There are many things in this world that we can't see with our naked eyes. Today, we came into this world in science class.

Last class, the science teacher asked us to observe insects and let us know the habits of aphids. But this time, we will use an optical microscope with a magnification of 100 to observe more subtle things.

The science teacher said, "This time we are going to observe the cells on the surface of onions." I was curious at the time. Does onion skin have cells, too? So I started this experiment with a question.

First of all, everyone assigned their own work. Hu Songyang and I observed other specimens, while Qianzhuang and Wang Qian made onion specimens. I took out the pollen specimen from the specimen and put it under the microscope. I opened my eyes and observed it together. Hu Songyang helped me adjust the mirror.

When there is enough light, I can see a light in front, and I can see a small creature inside. So, should I petrify the cells? I can't believe it. It is even more unusual to change another specimen, especially the mouth of a male mosquito. I was surprised to see something similar to a brain and a beard, but at the same time, the onion skin of the bank was finished. Together, we covered the onion skin with a glass slide and a cover glass and observed it under a microscope. At first, we didn't find it at all, even if we adjusted our position. When we were depressed, the bank shouted, right, right.

As soon as I heard this, I ran to the bank. I walked away in order to keep enough light. Finally, I saw, indeed, the cells of onion skin emerged in front of my eyes, which were silver elves connected one by one.

We quickly told Mr. Cheng our findings, and our findings were recognized. We are very happy. It is this lesson that makes us discover many unknown secrets, such as onion skin.

5. Review of "Micro-world" and review of composition micro-world in Grade One.

The weather has been sultry in recent days, and I feel a little uncomfortable. Bored enough to watch Jigong at home. Yesterday, I used the remote control as a pistol and filmed every boring program. When I turned on the chronicle channel, four words came into my eyes-micro-world. Hehe, I read it when I found it interesting. Oh ~ ~ ~ turns out to be a program similar to the animal world. I usually show the animal world to people I like, just. Hmm ~ ~ It turns out that the micro-world refers to the world of marsupials, and the casual corner may also be the small world of the jungle. All kinds of spiders use their own webs to catch prey, different spiders use different webs to catch different prey, and there are common waiting rabbits. There are also * * * collective hunters who win by number and can catch prey several times larger than themselves. Some spiders that don't weave webs hunt more widely. In order to catch more food and abandon the instinct of weaving webs, they evolved huge bodies and huge fangs, similar to the evolution of cheetahs who sacrificed their physical strength for speed. The team spirit of insects that ants can trample to death carelessly at ordinary times has been fully exerted. The migration and hunting of the group is not the instruction issued by the queen ant or other individuals, but everyone is collective.

Looking back, people have both natural and social attributes. Long-term evolution has reduced the natural attributes of human beings to instinctive behaviors such as breathing, eating and reproduction. In a highly civilized human society with high-rise buildings, there are no natural laws. Of course, nature is still higher than human beings. In human society, there is another set of survival rules. Selfishness replaced most things, and plunder became an act of making money. Disguised as hypocrisy Trade-offs and cooperation seem to be somewhat ineffective in human society. The only constant is the instinct to survive. Macroscopically, human beings are higher than other animals, but in this tiny micro-world, what are the skills and instincts that human beings can control or surpass?

6. A glance at the composition in the canteen, 200 to 300 words. Write the first day of school with macro observation and micro observation. As soon as we arrived at school in the afternoon, E799BE5BA6E4B 893E5B19E3133337623366 talked about the school canteen.

It is said everywhere that the food in the canteen is delicious! Is there any meat, what dishes to fry and so on. In this way, I feel that the three classes in the afternoon are not over.

After the third class, the sound of * * * sounded, just like the whistle at the beginning of the game. The whole class rushed out of the classroom and ran to the canteen. The door under the teaching building seems to be flooded, and the students run out of the teaching building, pushing and screaming.

In our class, classmate A is too active in eating. He took the lead in rushing out of our classroom, pushing left and right in the crowd in the corridor, looking for gaps everywhere in order to get to the canteen quickly. As soon as I came to the canteen, I felt that the temperature inside was several degrees higher than that outside, all because there were too many people inside, and I stayed in it for a short time and then I sweated.

There are so many people in the canteen that it is almost impossible to move. As a result, I squeezed hard and finally squeezed into the cooking queue.

We all stood there, waiting for the arrival of the food, but I suddenly found that there was no chef except a few tables in the cooking window. I don't know what's wrong, but I still stand there and see what's going on, or I'll run away when the meal comes.

I waited and waited, my stomach growled, but I still didn't see anything to eat. Suddenly a teacher came and said that there was no cooking in the kitchen. They misread the notification time.

Hearing the news, we can't wait to tear down this kitchen. Suddenly, another student shouted to buy noodles. When our hearts lit up, hundreds of students sprinted 100 meters in the canteen, rushing from one end of cooking to the other end of the snack bar to buy noodles, and almost knocked over the counter.

Seeing this situation, I immediately used my infinite magic to squeeze and finally grabbed a bowl of noodles. At that time, my heart was filled with emotion: ah! Oh, my god I finally have a meal.

7. A composition about chemistry is about 600 words. Chemistry is all around us.

What do you think of when you hear the word chemistry? Is it a complex reaction between matter and matter? Or those bottles of chemical reagents? Or a dense periodic table of elements? In fact, chemistry is not just these distant things, it is all around us.

Chemistry can be seen everywhere in life. The rust of steel, the digestion of food and the fermentation of yogurt … all these are permeated with the mystery of chemistry. Chemistry is so common, but so ever-changing. We must study it well in order to explore the mysteries of chemistry.

Chemistry gives us a better understanding of life. We can apply chemical principles to explain some common life phenomena, so as to understand the world scientifically. For example, why do green plants have the function of purifying the air? Because it can carry out photosynthesis under light, absorb carbon dioxide and release oxygen. This is a very common and important chemical reaction, which can also be used to show how important chemistry is to us.

We can use chemistry to improve our life. Some chemical reactions that are unfavorable to us can be avoided as far as possible by applying chemical principles, while chemical reactions that are beneficial to us can increase their occurrence rate. Chemistry can also make our life more comfortable. For example, air conditioning is a specific application of endothermic reaction, which can be used to reduce the temperature of air. In hot summer, it plays a great role.

Chemistry is a very useful subject, which attracts us to learn it, study it, explore it and apply it. It's all around us. As long as we observe and experience with our heart, we will definitely feel its beauty.
