Five 400-word papers entitled Discovery.

I find that spring has come: bloom is here, the grass is green, the wind is soft, the swallows are home, the weather is warm, and the streets and parks are much more lively? Below I sorted out the composition on the topic of discovery. Welcome to reading.

I find

I find that spring has come: bloom is here, the grass is green, the wind is soft, the swallows are home, the weather is warm, and the streets and parks are much more lively?

I found the environment more and more beautiful: the river in front of our school used to be a smelly river, with nothing on both sides and uneven roads along it. Everyone must have seen what it has become. The river is clear and green. There are several beautiful bridges on the river, and the path to school is clean and flat. This river has become a beautiful park and a paradise for our children.

I found the road wider and more crowded: Buchang Street used to be a very crowded side street. It turned into a river when it rained, so my mother had to roll up her trouser legs and carry me on her back. I don't know when it became so wide, so clean, so crowded and more lively than before.

From the first grade, I found myself suddenly growing up: my parents used to help me dress and wash my socks. Now I not only do these things myself, but also help them serve food, clean tables and sweep the floor. I also help teachers do their homework, clean the classroom and become a small student on duty. I know more and more words, so I can read books and newspapers by myself. My mother used to tell me stories, haha, now I tell stories to my mother.

Mom said that if you look closely, you will find more?

Discover beauty

A few days ago, some students from other towns and regions came to visit us, and we strolled around huinan town with great interest. They are amazed at the changes here, of course, compared with their last visit. I thought they were talking about tall buildings, widened streets and new pedestrian streets, but they shook their heads. These changes have also taken place in their places. What amazed them in huinan town was the clean streets, clear rivers, orderly traffic and friendly people.

I am silent. Living in this small town every day, coming and going in busy streets and quiet alleys, I actually found that these lovely and beautiful changes are not the only hardware now.

I remember once, on a windy day, the street was full of waste paper and plastic bags. When the wind stopped, the ground was a mess. Garbage rooms and public toilets are even more horrible and smelly, so people have to make a detour.

I remember that once, traffic lights and zebra crossings were useless, and pedestrians especially liked to cross the road.

I remember one time, the bus was crowded, the seat was robbed, the stability in the carriage was pushed, and the desire to stand comfortably was based on bad words.

When did the change begin?

It was found that the tourists all over the street were not messy at all, and everyone consciously threw the scraps of peel paper into the trash cans of different shapes on the roadside. In the garbage room, bags of tightly packed garbage are discharged in an orderly manner, and the outside of the garbage room is also cleaned up. No matter how strong the wind is, it can't afford to blow any garbage.

The discovery of spring

Come, come, I hear the footsteps of spring! Swallows whisper, Yuan Ye is covered with green, the earth bathes in spring, and everything is full of vitality. Hope, hope! Finally, look forward to another green spring.

How light the footsteps of Miss Chun are! She quietly came to the venue. You see, the rape blossoms in Huang Chengcheng have blossomed. Under the spring breeze, layers of Jin Lang surge, emitting a refreshing fragrance. They lifted their lovely smiling faces and looked at the sky innocently. The grass woke up from a sweet sleep, and they broke out of the ground, stretching their delicate arms, as if to show off the love of the spring girl.

Miss Chun came to the farmhouse yard. You see, the gold and silver branches in the yard are covered with star-like buds, and the green and yellow grass grows under the soft branches and dances gently against the blowing spring breeze; Under the eaves, a flock of swallows chirped as if to tell people that spring is coming, spring is coming! ?

Miss Chun came to the river, dressed it in new bright green clothes and sprinkled many wild flowers: white, purple, yellow, pink and blue. How beautiful!

Miss Spring came to the park and kissed the yellow grass. Kiss woke up the bare buttonwood; Kissed the sleeping peach blossom; She kissed the mirror-like lake blue.

Ah! Another beautiful spring, students? Don't be idle, white and sad! ? Don't miss a minute of spring, or you will regret it later! Let's work together!

My discovery

Autumn is crisp, and it is a good time to eat crabs. Dad's friend gave us some Yangcheng Lake hairy crabs. Those crabs are really big, one is only as big as a fist. Their bodies are covered with armor, and two big pliers are held high, just like a mighty general.

Our family ate with relish in the evening, but what about a few left? So, mom put them in the refrigerator. When I opened the refrigerator the next day, I found that the crab was motionless and even the big pliers hung feebly. Did the crab freeze to death? Or suffocate in the refrigerator. Mom said:? Dead crabs can't be eaten. ? I feel very sorry. If only I had eaten it all yesterday. So, my mother took them to the pool and planned to throw them away. After a while, suddenly, a crab's foot moved. ? They're still alive, mom. Come and see! ? I shouted excitedly. Then, other crabs move big pliers, slowly lengthen their bodies and spit out small bubbles. They are back to their original appearance.

What's going on here? So, I turned on the computer and asked Mr. Quan Zhi on the Internet: It turns out that in the low temperature season, crabs don't want to move and like to drill into mud holes to keep out the cold. And the temperature in the refrigerator is so low that the crab thinks that winter is coming and enters? Hibernate? State. So the puzzle was solved.

As long as you carefully observe the things around you in your life, you can find many problems and learn more knowledge.

Interesting discovery

Nature has many mysteries. Let's have a look!

One Saturday afternoon, it was clear in Wan Li, Wan Li. My parents and I went back to our hometown to help your grandparents clean up. While cleaning, I came across a spider web in the corner of the back door. At this time, a small flying insect flew slowly and accidentally bumped into a spider web. The little flying bug struggled desperately, but it was useless. The little flying bug is firmly stuck. Suddenly, a black spider crawled out from the side, came to the little flying insect and ate it with relish. In a short time, the little flying insect was eaten out of its shell. After eating, the spider climbed aside and waited for the arrival of other food. At this time, a question appeared in my mind: Why does a spider web stick to flying insects instead of spiders? With this question, I looked up information on the Internet and finally found the answer.

It turns out that because the spider has a lot of silk pulp in its stomach and small holes in its tail end, when it makes a web, it ejects these silk pulp, which condenses into thin silk when it meets air, so the spider uses these silk threads to weave a web. Spider webs are sticky. No matter what flying insects hit them, they can't run anymore, but spiders often secrete a layer of oil on their bodies and legs. So cobwebs don't stick to spiders, but to flying insects. I suddenly realized this. ? Oh, I see! ? I said with a smile.

I gained a lot of knowledge through this discovery. I must pay attention to observing nature and gain more knowledge in the future.
