My newly discovered topic composition

I believe everyone has tried to write a composition, especially the most basic and common topic composition in writing. The theme of topic composition is not extracted from the material, but triggered from the topic. The function of materials is to clarify the topic and inspire students' writing ideas. As far as the material itself is concerned, it can be written or not. What are the characteristics of excellent topic composition? The following is a collection of 400 words (3 general remarks) on my newly discovered topic, for your reference only. Welcome to reading.

My newly discovered topic composition 1 On Saturday, my cousin and I went back to our hometown to play. It was sunny at that time, so I went to my uncle's farm to play.

After I saw the pens of sheep, cows and ducks, I suddenly heard the sound of "giggle" and went to the chicken pen. I suddenly saw a chicken eat some grains of sand after eating its food. I thought to myself: huh? Why do chickens "switch careers" to eat sand? It has teeth? Still like to eat? or ...

These question marks have been spinning in my mind, and curiosity has made me find out. I followed the chicken, but it still didn't eat sand for ten minutes. Now there are several question marks in my mind: Is the chicken full? Or because I read it wrong? I went home and asked my cousin, "Brother, why do chickens eat sand?" Cousin is very helpless.

At noon, after dinner, everyone went to bed. I walked into the kitchen carefully, holding a mask, gloves, scissors and a magnifying glass, holding a chicken's belly and cutting it open with scissors, and found that there was sand in it. I looked at it with a magnifying glass and found some chicken feed stuck next to the sand. I thought again: won't sand grind the stomach of chickens? There were more and more questions. Finally, I decided to go back to my house to wash my hands and look up information on the Internet. Finally, I found out the truth.

It turns out that chickens have no teeth and cannot chew food like people and other animals. But by eating sand or pebbles to grind food, and then these sand or pebbles can be excreted with the ground food! Chicken's stomach is thick and hard, and it will not be worn through by sand or stones.

The truth has finally been discovered, and my new discovery is really interesting!

On that day, the afterglow of the sun dissipated like a gust of wind, replaced by silver moonlight, which gradually filled the sky.

Finally, I finished my homework, packed my schoolbag, put on my shoes as quickly as possible and rushed out of the house. Today I finally don't have to listen to my mother's nagging, yeah!

Out of the yard, my mother and I walked into the road. Silver moonlight, bright moon, how beautiful! There is not a star in the sky, as if shocked by the beauty of the moon and ashamed to show up. Therefore, the moon monopolized the dark sky and sent soft silver light to the earth.

When we were walking in the moonlight, I looked up and the moon was above my head. I took a few steps, but it still didn't move. There was a flicker of doubt in my mind, but this feeling was immediately replaced by happiness.

"Mom, look!" I walked up to my mother and said, "Where I go, the moon goes, which shows that it is my good friend!" " "

I thought my mother would admit it right away, but suddenly she burst into laughter. I said angrily, "Am I wrong? Didn't it always follow me? " "Silly boy, you are too naive. You can go home and check the information and see why. " Mom said.

When I got home, I immediately turned on the computer, looked up information on the Internet, and suddenly realized.

It turns out that the moon is no friend of anyone. Because the moon is too far away from the earth, there is no reference in the air, so we make our own reference, so we think that the moon is moving with us, but in fact it just turns slowly around the earth.

"Oh, I see." After turning off the computer, I sighed: "Moon, you are really a naughty guy. People are really unpredictable!" " "

This is my new discovery.

My new discovery topic composition 3 I have made a new discovery recently, that is, there are more and more private cars in the community.

Cars do bring a lot of convenience to our lives, but with the increasing number of private cars, the taste of traffic jams is really unpleasant. Today, I personally experienced the advantages and disadvantages brought by cars.

Early in the morning, my father drove the family taxi and took our family to visit the grave in Xiaoshushan. We used to go by bus, on the one hand, we had to wait, on the other hand, we had to stand if there were no seats, so tired! At first, the road was quite smooth. While enjoying the scenery, I chatted with Brother Rui. However, as soon as I got on the viaduct on Changjiang West Road, I found that the vehicles in front were driving very slowly, and even the viaduct was blocked like this. Dad sighed and said, "Look, at this rate, I don't know when it will arrive!" "

In this way, the car stops and stops, and the traffic radio in the car broadcasts the latest road information from time to time, as well as the best route for private car owners to go to Xiaoshu Mountain. I was sleepy, and my brother patted me and said, "Jiayi, look, that's our school." Xiaoshan Mountain is just ahead, and we are going to our destination. " I pulled myself together again and looked out, only to see the crowds on the road. Nearly 80% of the traffic is private cars going to Xiaoshushan to sweep graves. Because of the huge body, the bus can only pass through a pile of private cars.

When I came back from sweeping the grave, the road was very smooth, which took only about 30 minutes, but I walked for an hour and twenty minutes.

Students, this is a new discovery in my life. Tell me what you found!
