Mystical semi proposition essay 300 words

In my happy childhood, there were many discoveries, although not surprising, but always exciting, but there are always some memories that cannot be erased.

One day, the teacher of the Happy Composition Class did an experiment for us, she found a glass, a candle, a stick with a circle of wire, and a paper cup, and then she put the paper cup into a circle surrounded by wire, lit the candle, and put it in the glass. Finally, she hung the paper cup over the candle to heat it.

A few minutes passed, the bottom of the paper cup slowly turned black, but the paper cup never burned, the students were very puzzled, felt incredible, driven by curiosity, the students rushed up, all want to see what is going on.

To our surprise, the paper cup was not broken! The teacher looked at us with a puzzled look on our face, and told us with a smile: "Water has a boiling point, which is 100, and paper has a fire point, which is 110, so it should be that the water boils first, and the water is boiled dry, and the paper cup will be ignited." ”

When we heard this, it dawned on me that I learned something new today. There are many mysteries in this world waiting for us to explore, to discover, to acquire.

Composition is very important for each of us. As a student, composition is a subject and a yardstick to measure language achievement. Stepping into society and participating in work, composition is inseparable from us.

Journalists, writers, etc., this kind of composition elite has to rely on writing essays to eat, and if they can't write essays, they have nothing to eat. For most of us, although it is not a problem of employment, it is also indispensable. For example, thank you letters, proposal reports, inspiration posters, contract conventions, blog text messages, IOU reviews, etc., are proposition essays that we must encounter in our lives.

We know the importance of composition for everyone, but the question is how to write a good composition? Composition is a way for us to express our thoughts, a continuation of our language communication, and an indispensable theme for our life, study and work. Narrative, lyrical, argumentative, expository, and practical are the five genres of composition, and all the essays we write are included in these five genres.

When we need to write an essay, the first thing to do is to review the rules and determine which genre to use to write the essay.

My day on the moon.

The spacecraft landed smoothly on the moon, the hatch slowly opened, and I landed on the moon.

For a moment, I was stunned by what I saw, and I couldn't believe my eyes: water parks, playgrounds, schools, shops, residential buildings, and more. The outermost layer of each building is golden, which can reflect sunlight to a converter, not to mention that this converter is not big, all the energy on the moon comes from it, because it can convert light energy into heat, mechanical energy, chemical energy and other energy, and can be transported to various places through the pipeline.

There is also a place on the moon dedicated to collecting dust from the body, and people can get there and sweep away the dirt from their bodies. Then you must ask: how can there be so many people?

Let me tell you, it only takes two or three seconds to wash a person, and as soon as people walk through the door, the body cleaning is done, and it is very easy.

Everyone knows that there is no air on the moon, how do people live? I also know this very well, and I have to carry an oxygen cylinder on the spaceship. But on the Moon, that's no longer a problem.

People only need a tube, and the oxygen supply base will provide you with oxygen. The tube can be long or short, so it is very convenient to walk without tripping.

As the day's journey drew to a close, I stepped on a spaceship and was reluctant to leave the moon.

Fantastic computer.

I have a computer at home and it's amazing. Everyone in our family needs it. Dad used it to look up information, Mom used it to surf the Internet and watch movies, Grandpa used it to play chess, and I used it to study, play games, and watch cartoons.

Nowadays, children's programs on TV are all programmed, but watching cartoons on the computer is different. You can watch it whenever you want, you can watch which episode you want, pause when you want, rewatch it if you want, and rewatch it whenever you want, very free. The games on the computer are also very fun, such as my favorite games such as Angry Birds, Plants vs. Zombies, and Fantasy Games

Because I love to play games, computer games have become a special reward for my father. Whenever I finished studying, my dad would reward me with a certain amount of playtime. There are still a lot of good songs on the computer, so you can listen to whichever one you want.

If you have any questions that you don't understand during your studies, you can also look up the results on the Internet. For example, the accurate pronunciation of English words and the interpretation of ancient poems. Whenever I find the result, I am as happy as if I have won the lottery.

The computer can also be used as a drawing board to draw beautiful pictures, and now our microcomputer class also teaches us to use "Jinshan Painting King" to draw it. You can also use it to shop online, for example, I picked out a box of Barbie dolls online with my dad that day, and I liked it very much when it arrived at home. And the computer can also be used as a ****, our family and my second aunt's family are not in the same city.

I'm in Benxi, she is rented in Fushun lead, and we can only meet during winter and summer vacations, and now we can chat at any time with a computer, just like sitting face to face. The computer is so interesting, it can become: learning machine, game console, drawing board, TV, and can also become ****.

There are so many features that the list is endless. The computer is like a brain that uses electricity, it has a lot of knowledge in it, it is amazing, I will also learn to use the computer in the future, so that the computer can become my friend, a learning tool, and a good teacher for me.

An ordinary painting may not catch your attention. However, there is another secret in an ordinary painting.

One day, my father bought a painting from out of town. My father said to me mysteriously, "Don't touch this painting, it's magical?"

So, Dad put the painting in his study. I asked my father, "What's so magical about a broken painting?"

Dad said, "Hehe, you don't know that!" Because the painting has different colors during the day and at night.

How is it possible that the same painting has different colors during the day and at night? My heart was filled with curiosity and I decided to watch it again in the evening. In the evening, while my father was not looking, I sneaked into the study.

The results were beyond my expectations. The painting is still bright during the day, why does it turn dark yellow at night? Did any special pigments be used?

I screamed, but my father heard me, and he walked over quickly and boasted, "Look, it's amazing!" Well, it's out!

After watching this magical scene, I pondered and looked for the reason here, but I still couldn't figure it out. So, I went to look up the information. After an hour, my efforts finally paid off.

It turned out that it was all the electric lights that were doing the trick. Because the color of the opaque thing is determined by the color of the light reflected back from his body. During the day it is bright because of the blue light reflected off its body.

The reason why it is dark yellow at night is that the most light in the electric light is red and orange, while the blue light and purple light are pitiful. That's why a painting doesn't have the same color during the day and at night.

I discovered the reason why the color of a painting is different during the day and at night, and I felt beautiful in my heart. At the same time, I also know that there is so much knowledge in an ordinary painting, so how much knowledge in nature is waiting for us to discover! So, we need to be attentive now to learn more about the natural world.

I discovered the unifying power of ants.

I like ants, not only for their hard-working and simple character, but also for their spirit of helping each other and forging ahead in times of crisis.

I remember one time, a few ants were hurrying on the wall. I got up in the moment, poured water from my teacup, and threw it at the ants, who were frightened and ran away. I flooded them with water, and they were all covered in droplets of different sizes.

Although the tenacious little ants are trapped in the water, they still do not give up the opportunity to escape. They spread their calves thinner than a needle and crawled desperately to the dry place, but it was too late, and the bean-sized droplets stuck to them like glue, making it difficult for them to walk. At this juncture, I saw them in a circle, hand in hand, fighting bravely, and finally broke out of the encirclement, exhausted, lying back to back, encouraging each other.

After a while, the long queue was up again.

Their team walked in the direction of the cake crumbs that the rats had eaten, and then, the cake crumbs the size of broad beans were gone, and I moved the cake crumbs to another place, and the ants were not to be outdone, and they immediately found food. At this moment, a swarm of ants came over, and the cake crumbs disappeared from my eyes immediately.

I looked at the group of ants and sighed, it is true that ants with the size of rice grains are sometimes stronger than some people.

Fantastic book.

Although I am active and active, I prefer to swim in the sea of books. In front of the breezy window, as long as I have a book to accompany me, then I don't want to go anywhere.

Book, as much as I am so obsessed with you, I hope you can enter the hearts of more people and become their good friends. So I often thought: how nice it would be if there was a magical book with words printed on it, and it could turn the words into beautiful language!

With such a book, we can still hold the book and study in the dark. This page has been learned, easy to do, turn another page! It will read to you as you ask it to be.

If you give this book to grandpa and grandma, then they don't have to wear reading glasses. The old people sit leisurely on the sofa, as long as they free up a pair of ears! It doesn't matter if you have the back of your ear, there is an adjuster in the book, and the volume can be adjusted!

If you give this book to blind children, they won't have to touch Braille. Look, the blind children are learning attentively and smiling sweetly with their little red faces with their magical books in their hands!

I love books, and I wish there were such magical books!

Once upon a time, there were two countries on Earth - OK and NO. The country of ok lives a self-righteous banana king, while the country of ok lives a learned and humble apple king. The country of OK is very strong and rich in products; But the country is poor and backward.

One morning, a scientist came to OK Country and wanted to meet the banana king. It was noon when the banana king got up. He came to the parlor.

The scientist said, "Hello, King! My name is B. Squirts.

I brought something magical. When the banana king heard this, he immediately said, "Take it out and have a look."

B. Skiss immediately took out a cube and gave it to the banana king, and said, "This is the clock, with which you can control the time and arrange the time reasonably, which is very magical." When the banana king heard this, he became angry:

I thought it was something, it turned out to be such a thing. We don't need time. Let's go!

B. Squirtes came to の country again, and the apple king knew about it and came to greet him immediately. After listening to B. Schis's introduction, the apple king immediately bought all the more than 100 bells of B. Schis, and asked B. Schis to stay in the country as a national teacher.

Time flies, and two years later, the country of NO has changed dramatically. の country is becoming strong imperceptibly, too. The national teacher B. Squies proposed to attack the OK country, and the Apple King was pleased to accept this opinion and personally led his troops into battle.

At this moment, the banana king of the OK country panicked and immediately sent the watermelon general to meet the battle. The battle began, and the soldiers of the country cherished their time and insisted on training every day, so they were all strong, brave and good at fighting, and could defeat one against ten; Although there are many people in the OK country, they are self-righteous and negligent in training. As a result, in just half an hour, the army of the country of NO killed the army of the country of OK without leaving a piece of armor!

Two days later, a battle report came from OK Country: "General Watermelon is defeated and has died on the battlefield." "The banana king was so scared that he had to fight himself, but it was too late.

The NO country eliminated the OK country with a strong offensive.

Since then, the NO country has become stronger and stronger, and it has become a real OK country!
