Write an essay about the scene of the event you participated in

A big cleaning The big cleaning has begun! The students rushed to their labor positions. Some swept the ground with brooms, some wiped the blackboard with a board, and some placed the tables and chairs neatly.

Step aside! Step aside! I saw Wang Mingming carrying a large dun cloth and walking into the classroom.

He dragged the floor most seriously, waving the wet cloth and wiping the ground clean. Zhang Fang is responsible for setting up the tables and chairs, you see, she sets the tables and chairs horizontally and vertically at a line, and whoever sees it makes a "tsk" exclamation. The health commissioner asked me to clean the glass, and I picked up the rag and climbed onto the windowsill and started wiping it one by one.

It had just rained, and there were many small mud spots on the glass, which was a lot of trouble to wipe. I first wiped it with a damp rag and then wrapped a dry rag around my fingers to wipe the entire area of the window frame. Hey, that mud speck is gone all at once.

Through the bright glass window, I saw the small trees on campus nodding and smiling at me!

The tense cleaning ended with the laughter of the students.

Everyone has special activities, such as cycling competitions, drawing competitions, running competitions, and other activities held by themselves.

The special event I would like to mention is the "Red Scarf Flea Market" that our school hosts on Children's Day. The "Red Scarf Flea Market" was held to commemorate the Wenchuan natural disaster. On this day, all the students took their own things, such as discarded newspapers, books, toys, etc., and put them on the playground, set their own prices, and bought and sold them at will.

Then, donate the money to buy things to the children who have lost their homes in **, so that they can live a better tomorrow.

On that day, the market was crowded with people, and the places in the shade of the trees were full of people, and not a single person was in the sun. Many students have brought a lot of items to sell, and also bought a lot of items, each other's ** is very cheap, most of them are jumping prices, some are discounted, some are 2% off, and some are ,...... discountHowever, my family conditions are not very good, my parents did not give me pocket money, and I did not have much money to bring. So, I brought my favorite books and toys to buy, which were all birthday gifts from my parents before.

When my classmates bought them, I was very upset, but in the end I reluctantly bought them at a low price, because I had no money and I had to donate money. I think this event is very meaningful, everyone is expressing and conveying their hearts in their own way, and this is a special event.

In this event, I learned that as long as the mind is there, it is more valuable than anything else. **Internet.

Fun garden activities.

On June 1st, our school held a garden tour to celebrate "June 1st".

The garden activities include sticking noses, dribbling table tennis (obstacle course), pinballing, basketball dribbling, you shoot and I catch, and guessing riddles.

It's fun to stick the nose, the teacher first draws a clown on paper, and then uses a magnet to stick the paper on which the clown is drawn on the magnetic blackboard. When someone came to play, they covered their eyes with a red scarf and put their nose on the clown. Some people put their noses on the clown's ears, some put their noses on the corners of the clown's mouth, and everyone leaned forward and backwards with laughter.

But the teacher still gave the prize, because the teacher said that it only needs to be put on the face.

Dribbling basketball is also a lot of fun, and this game requires two people to play together. The two of them are back to back, sandwiching the basketball in the middle, walking sideways like crabs, which is more difficult, and if the pace of the two is slightly uncoordinated, the basketball will fall and end in failure.

I decided to play pinch marbles. The marbles were clamped in our classroom. There were a lot of people, but they were in good order, and there were long queues from the podium to the wall at the back. I stood at the end of the line.

When it's not my turn, I just "watch". There was a "match" between Li Tianhao and the first-grade children in our class. I think:

Against such a small classmate, Li Tianhao will definitely win. Who knew that the little classmate was too powerful, I saw him holding chopsticks in his small hands, looking calm, unhurried, and pinching the marbles out of the water one by one. In contrast, Li Tianhao seemed a little scrambling, but lost.

I thought: Li Tianhao, Li Tianhao, what a shame it is for you to be defeated by such a young classmate!

There is also a "battle" that is more fun. It's two big brothers who are competing, one brother picks up a marble and puts it in each other's basin, and then picks up one and puts it in each other's basin. It made us laugh.

Finally, it was my turn to play, and I was in my classmate, Zhou Jiahaobi. Zhou Jiahao is two years older than me and is much more capable than me. Therefore, I was very nervous, not much better than Li Tianhao, my hands were a little shaky, and my heart was like a little rabbit, "pounding" and jumping, and sometimes the bullets that had been clamped fell into the water again due to the shaking of my hands.

So there was a draw with Zhou Jiahao. The teacher gave each of us a jelly strip.

It was so much fun and we had so much fun! (Original Composition).

If the ratio of the mass of the two liquids A and B mixed (excluding heat loss) is Ma:MB=2:3, and the temperature of liquid A increases by 10 and liquid B decreases by 15 after mixing, then the ratio of the specific heat capacity of A and B is?
