200 words composition of Qukou International Convention and Exhi

1. If we say that there must be a 100% and safe method, which does not involve moral issues, and most people can do it, then only gambling, which has skills, can be regarded as a loophole. No matter how much the principal is, we can make a 100% yield of 10, that is, 100 becomes 110, 1000 becomes 1100, 10000 is 11, 000

2. This afternoon, the head teacher led us to the calligraphy classroom on the third floor of the north building to visit the homework exhibition of grade two to grade four

first of all, the hard pen calligraphy works of grade three and grade four come into our eyes. Every piece of work can reflect the students' meticulously and constantly improving spirit. Among them, I think Li Chenxi's works are the best in writing technetium. Every pause and move of her pen reflects the depth of her Kung Fu; Every word is so beautiful. If you look at my handwriting again, it's not bad, but it's a bit inferior to Li Chenxi's

next, we will visit the compositions of grade two to grade four. I'm very good at writing books and doing math homework. Especially in their compositions, the language is vivid, beautiful, neat and elegant, and there are no typos

when I came out of the calligraphy classroom, I was filled with emotion. Why do we study in school the same way and show different abilities? If there is a gap, we should work hard to catch up. I have gained too much today.

4. The annual children's Day is coming, Dad's company&# 173;—— The leaders of Xiamen ZhuZong Property Management Co., Ltd. are concerned about the healthy growth of the children of the grass-roots employees. They are considerate of the employees who are busy at work and have no time to take their children to play. In particular, they organized a play and exploration activity for the children of their families
on the morning of May 30, it was sunny. Dad and I, as well as some of his colleagues with children, went to Song park to take a bus to play. When we got to the park, we were very excited and trotted all the way to the bus. Maybe we came a little late, the bus is almost full, the car is full of children's laughter. After checking the number of people on the bus, the company's aunt drove to the science and technology center
with the bus, we crossed the sea bridge - Xinglin bridge, and soon came to Chengyi science and Technology Exploration Center. The company leaders have welcomed us at the gate. The science and technology center is divided into four floors. We all lined up and got tickets one by one according to the company's arrangement. After entering the second floor, the staff guided us to the second floor. Many people can go to the third and fourth floor first, where there are natural disaster experience area and space exploration area. A few of our children were very happy. We took the elevator to the third floor and listened to the explanation of the staff as we walked, "how terrible the earthquake and debris flow are, how small and helpless people are in front of nature." We came to the fourth floor, where we had the knowledge of human successful exploration of space, such as Tiangong-1, Shenzhou rocket... The staff introced us a lot of knowledge, but I couldn't understand some places, but my father gave me detailed answers one by one, which made me deeply realize that only through careful reading can we discover and explore more useful knowledge for human beings. Today, through the simulation model, let me further understand the great discovery in exploration
after walking on the third and fourth floors, we took the elevator back to the second floor. There is a space-time shuttle on the second floor. I asked my father curiously what time shuttle is. He said that it is a tunnel idea to bring us back to the world before and in the future. We queued up in order and got into a small boat like aircraft. The staff gave us a 3D glasses, saying it would look more real. The aircraft began to move. According to Dr. spaceshuttle's explanation, it put us into a space-time tunnel imitated by 3D technology. It seemed that we were brought back 100 million years ago, back to the age of dinosaurs. The scene was very real. The pile of dinosaur eggs seemed to be around us. We wanted to reach for one, and then there was a terrible scene of dinosaurs eating small dinosaurs. Then a strong wind blew in front of me, and the mouth of the dinosaur "bit" us, as if to eat us. At that moment, I cried out in fear. My father comforted me not to be afraid, so he put his hand on my shoulder to give me courage. I couldn't help sighing: this 3D simulation is too real! After another turn, we entered the virgin forest. After a turn, we entered a future world. We saw airplanes hovering above the building. We ended this wonderful journey, but it gave me a happy and unforgettable real experience
we quickly went to the first floor. There was a natural disaster refuge area on the corner of the first floor. After we entered, the staff explained in detail how to avoid danger, self-protection and safety precautions. After coming out, we went to play some amusement facilities, we were very happy. Through this exploration, I had a long knowledge and happy children's day this year. Because my sister did not come to participate in this exploration, my father's company has a beautiful gift for her
thanks to my father's company for giving me an opportunity to increase my knowledge. I am determined to be a person who studies hard, explores and discovers science. Even my father said, "the leader of the company is so considerate of the employees. There is no reason why he doesn't work hard and seriously. In the future, he will obey the company's arrangement and create better benefits for the company and the society."

5. Water level alarm Wang Huanran, class 4 (2) of Jiyang Experimental Primary School in Zhangjiagang City, Jiangsu Province, once put water into my bath. After I turned on the tap, I read outside with great interest. I forgot to turn off the tap. As a result, the water in the bathtub was almost overflowing. I think: if the water in the bathtub reaches a certain height, it will send out an alarm to remind me that there is too much water. How nice! So, my mother and I went to the Internet to search for relevant information, and really found a small proction called "water level alarm". I found a plastic bottle and a music card. My mother helped me find the wires. We also took out scissors, transparent glue and ribbon... All the materials were ready. We first cut the music card, carefully studied the sound principle of the music card, and carefully connected two wires. I cut off the upper part of the plastic bottle, dig a small hole in the middle of the bottle, insert the two wires into the hole, and then tie the two wires in the middle and lower part with a cow leather band and a color band to make a red "alarm line", and then adjust the height of the wire. The long one extends to the bottom of the bottle, and the short one just extends to the alarm line. I used transparent glue to circle the outside of the bottle for fear that the wires and music cards would fall off. Mother said: "pure water conctivity is not strong." In order to enhance the conctivity of water, we decided to add some "ingredients" to the water supply. I made a small salt bag with a small plastic bag and my small socks, filled with salt and put it into the water level alarm. Finally, I used bows and ribbons to make the water level alarm look beautiful. The water level alarm is ready. We should try it. I slowly poured water into the water level alarm. When the water level rose to the alarm line, the music "diddidi" suddenly sounded and the red light flashed“ WOW! We made it Suddenly, my mother and I cheered up. This water level alarm is just a model. When I grow up, I must make a real water level alarm, so that science can benefit people.

7. Small fair

today, our class held a meaningful activity --- small fair

the students brought a lot of things they didn't use, including books, toys, and daily necessities... The exhibition began, and the classroom became lively. The students ran around and began to look for what they needed, and I was no exception. Just as I was walking around, I suddenly saw a book "complete works of composition". I opened the book, turned to the page of the catalogue, and looked at the content carefully. There were many compositions I wanted to see, and I wanted to get it very much. I deliberately asked calmly, "how much is it?" The student who sold the book held out four fingers and said, "four yuan." I said with a smile: "two yuan and fifty cents is OK?" "At least three yuan," he said I think the price can only be like this, then said: "deal." So I gave him three yuan and he gave me the book. I was very happy to get my favorite book. Soon the fair was over and the students got what they wanted

after this exhibition, students have learned a lot.

8. During the summer vacation, my cousin and I made an appointment to play in Yanqi Lake Park, where there are many amusement projects, including pirate ships, flying saucer chariots, go karts, mini rafting, water speed drop... It really made our brothers addicted
my favorite project is the pirate ship. The rule of the pirate ship's game is to use the bow gun to hit the animal model in the lake. If it hits, it will spray out a spray of water and then disappear into the water Teacher's comments: clear and fluent expression is very valuable for children who have just entered the third grade.) My brother started the boat in the back. Oh, no, the boat hit the animal model. I fired the gun in a hurry, and the animal spurted a spray of water onto us. My brother cried out, "Oh, I'm so cold!" Looking at my brother's embarrassment, I said with a smile: "don't be afraid of cold, it's just a game." Later, I proposed to compete with my brother, and he agreed. I'll shoot, brother will sail; I'll take the boat, brother. Take the gun. Every time I can kill two birds with one stone, my brother is always not sure, so he didn't get a point, and finally had to admit defeat
what a happy and unforgettable trip!
