Looking forward to the day of swimming, we did warm-up exercises first, and then got excited about the groundwater like a flock of ducklings. Wow, the water is so cold! I don't know anything about swimming, but seeing other companions eager to try, I began to learn slowly by taking a breath.
"poof!" After drinking several mouthfuls of water in a row, my nose is sore. I thought angrily, well, what's the big deal? Is it just to catch my breath? Still want to beat this young lady?
With this idea, I learned to breathe and began to slide. Sliding is very important in swimming. It can make you swim quickly and easily. Facing the water of 1.20 cm, I just dare not slip out. That deep water is no joke! After seeing it, the coach said to me calmly, "Overcome the psychological barriers and swim boldly forward."
After listening to this, I learned boldly. He also taught me to play football, which made me make rapid progress and the coach was very happy.
After 10 days of hard training, I finally mastered the skills of breaststroke. This is the result of my efforts since 10 days.
How time flies! 14 passed in a blink of an eye, and I also learned all kinds of swimming postures, ah! This is really a happy summer vacation!
Diary of summer vacation for the fourth grade of primary school 2 got up very late today and kept watching my daily diet in the house. I'm ready to have a good time on the trestle. But dad has something to do. 10 Let's go. I'm rather disappointed. I went to room 509 again to watch TV with Li Yongrui.
It's ten o'clock and it's raining outside. So, we got on the tram 30 1 and left. But I'm carsick again. We wanted to get off, but we didn't get off because I vomited. I suddenly sat down 2 kilometers away from the trestle. Then we eat wonton.
After eating chaos, I walked to the trestle. On the way, we saw 3 meters of crabs, 4 meters of colored lobsters, octopus, marine fish, curry and abalone. And drank delicious abalone soup. It is delicious. We arrived at the trestle and the rain stopped. We caught up with the low tide and had a good time. Ah, it's 5 o'clock! We hurried to a restaurant and had a meal. At 7 o'clock, we arrived at the railway station and slept for an hour. At 8: 03, our train started. We played 1 hour and 59 minutes on the train. 1 1 o'clock, we are home.
Three interesting math problems can exercise children's brains. Here, I would like to share the summer vacation math diary of the fourth grade students in primary school, hoping to help everyone with their study!
Today, my mother gave me a question 3ⅹ3=? I snickered to myself, thinking that my mother had studied for so many years before! I can't believe I asked such a childish question. So I answered absently: "3ⅹ3=9." Mom asked me 33ⅹ33=? I did some calculations on the draft paper with a pen, and I got 1089. I will answer immediately.
Then my mother asked 333ⅹ333=? I got 1 10889 after a stroke of calculation, so I answered my mother's question again. Mom seemed dissatisfied and asked 3333ⅹ3333=? I suddenly froze. This is because my mother stopped asking, but asked me if I found any patterns. I read every answer carefully and finally understood. It turns out that each number is 9, ten numbers are 8, and the highest number is 1. Each occurrence of 1 3, 1 and 8 in the two factors increases by 1 respectively. I immediately got 1 1 108889 from here. We also know that we can use this law to solve many problems. I immediately told my mother about this rule and the bright smile on her face.
At this time, I deeply realized that "nothing is difficult in the world, nothing is impossible to a willing mind". This realizes that as long as we observe carefully, nothing will baffle us.
The above is what math diary, a fourth-grade primary school student, shared with you during the summer vacation. I hope it helps you.
Diary of summer vacation in the fourth grade of primary school: Today is the day to receive report cards. It is also the day before the summer vacation. I don't know whether it is a sunny day or a good day chosen by the teachers. Today is not only the first day, but also the last day!
I'm a little scared when I get to school. According to He Maojun, it is "waiting for death". I gasped, too. It is said that my Chinese exam is not very good. The result is waiting for me: 92 points in the Chinese exam! Shit! Why is it so low? "Death Prophet" Zhao is right! I can only watch my competitor Xi Zhihong show off in an ostentatious manner, and my heart is very unhappy.
There is a prize! I won four prizes and many prizes, so I won't be so miserable when I go back. Well, there are really countless prizes. After all, they are my "salary" for a semester!
There are prizes and homework. What luck this time! Math and English have finished their "summer homework", and others only need oral review. Even Chinese only needs to keep a diary and feel after reading it!
When I got home, my father thought I was too fat and said, "You are going to learn to swim and ride a bike this summer vacation." Although I don't know these two things, I can skate, ski and skateboard. )
This is the day before my summer vacation.
Today is the third day of my trip, and I can finally visit the dinosaur museum I want to go to most. As soon as I entered the gate, it seemed to take me into the distant Jurassic era. We first visited the dinosaur fossil exhibition, and two Mamen Xilong dragons looked into the distance. The other is looking at a little dinosaur and many other models. The tour guide told us that the dinosaurs in Zigong are widely distributed, abundant, well-preserved and rare in the world, which is the essence collection of dinosaur museum. Hearing this, I know that dinosaurs in Zigong have found the most fossils in the world.
Then we visited the dinosaur skull fossils, the crocodile, a close relative of the dinosaur era, and the place where the dinosaur died at that time. There are many bone marks left by dinosaurs after their death in this place. Later, we climbed Longshan again and saw a big dinosaur biting a small dinosaur model. There are four big characters engraved on a big stone next to it: jungle. The tour guide said that there are three possibilities for the extinction of dinosaurs: one is that asteroids hit the earth, the other is that volcanoes erupt, and the third is that the dinosaur food chain is interrupted. Now scientists who hold this view can't convince anyone, because they all have their own basis.
Walking out of the museum, I seem to have just walked a circle from the dinosaur era and returned to my own world.
Summer Diary of Grade Four in Primary School 6 20xx July 7th Wednesday Weather: Cloudy.
After lunch, I picked up the happy composition and reading on my desk and started reading after class as usual. Suddenly, an article titled "Failure with a Prize" came into view. Will there be rewards for failure? I can't wait to read it with full of doubts.
This article is about a little boy. Seeing that his mother has published many articles, he sticks to the Internet all day like a spider and contributes to a children's magazine from time to time. Once or twice, he failed again and again, and finally, he kept an article. However, the article failed to pass the final review. The boy's mood is unusually low. At this time, he got a prize-the comic book he dreamed of. His mother told him, "this is a failure award." Reward him for bravely challenging his mother, diligently practicing calligraphy and making great progress in his composition. Later, the mother often encouraged the boy's failure in the form of "failure award", and the boy's study life gradually became brilliant, and he became more brave and confident in the face of failure. ...
In fact, in our study and life, we often encounter some setbacks and failures. At this time, parents are either furious, severely reprimanded or sarcastically attacked. I really envy the boy in the article. He is lucky to have a wise mother who can see his efforts and progress in failure.
I remember when I was in the third grade of primary school, I participated in a recitation contest organized by Little Rising Star English. Although I know the contents of the contest by heart, I didn't enter the semi-finals in the end. After knowing the result, my mother's reproachful expression, the teacher's disappointed eyes, the classmate's wry smile eyes … Alas! At that time, I really hoped that someone could give me some comfort, affirm my efforts and give me an encouraging word. ...
Not long ago, Little Rising Star English organized a new recitation contest, and both teachers and parents wanted me to participate. Can think of the previous failure, my heart is pounding, and I really have no confidence to participate again.
I must show this article to my mother. When I fail again in the future, maybe my mother can face it with me, at least there will be no more storms.
The summer diary of the seventh grade primary school saw in the Southern Metropolis Daily today that the annual interest rate of the bank was adjusted by 0.27%. The deposits and loans of a bank are as follows: 5.3 1%5.58% deposits 1.98% loans, 2.25% after adjustment.
From this table, I found out why we should adjust 0.27%. The adjusted interest is 2.25 ÷1.98 =1.1.3 times the original interest. If I deposit 100 yuan, the profit of the previous year (given to you by the bank) is 1.98 yuan, and I will give you 2.25 yuan after adjustment. If I save 10,000 yuan, I will have 225 yuan. Now it costs 5.58÷5.3 1= 1.05 times more than before the adjustment. If I borrow 100 yuan, I will pay back 5.3 1 yuan the year before the adjustment and 5.58 yuan after the adjustment. If 1 10,000 is borrowed, 53 1 yuan and 558 yuan will be paid back before and after adjustment.
Today is an important day-I'm going to take the piano band 6 exam. My mother said that I don't have to play the piano today after the exam. I wish I could finish the exam as soon as possible!
Although I am a battle-hardened veteran, I am also nervous. Seeing that other candidates played so well, I was worried that I could not beat them, and my heart was pounding. "Wang, it's your turn!" It's finally my turn to play. I sat on the piano stool and began to play music. The first is the basic exercises-scales and arpeggios. I play F major and E minor, and I am fairly fluent. Then there is the etude, which is relatively simple. I had a good time. Then polyphonic music. I didn't play very well. Fortunately, the teacher stopped it in time, so I didn't trip. The last piece, this is my "masterpiece"-Polka, this is the best piece I have ever played. The grading test is finally over!
It took me six months to pass the exam. Through this exam, I found my own shortcomings, of course, there are advantages, I will correct them next time and do better in the exam!
It doesn't matter if you have a cup and an egg, but adding water and salt has a little secret.
On Sunday morning, there was a power outage at home, so it was deserted and I couldn't watch TV. Playing computer is boring, so I started an experiment in the strong sunlight. I first took a naked egg in the refrigerator, a cup full of water in the kitchen, prepared something, and began to do the experiment. I gently put the egg into a cup filled with water. I watched quietly, and the eggs kept floating on the cup. I wonder if I can make the eggs in the water sink to the bottom. I think carefully with my clever head, and while thinking, I walk around the kitchen leisurely. I glanced at the seasoning with my eyes. In the blink of an eye, a bag of edible salt appeared in front of my eyes, "Oh! Salt has weight. I can put a little salt in the water to make the eggs sink. " I said to myself. Then I picked up a bag of edible salt and put a few spoonfuls in the water. I focused on the cup and saw that the "disobedient" egg finally sank to the bottom of the cup in a short time. Dad came back and I told him my surprise. He praised me for my wit and intelligence.
In fact, science is around you and me. As long as you observe carefully, you will find a lot of happiness and secrets!
Summer Diary of Grade Four in Primary School 10 Care is selfless, and happiness is infinite! Tolerance and forbearance are great!
The playground was crowded and lively. Some are skipping rope; Some are running; Others are playing volleyball.
I sat quietly on the playground and looked up at this beautiful and happy "picture". Suddenly I saw a little brother kick a little sister in grade two or three, and the little sister fell down. My little sister stood up strongly, and I stopped my eyes on this little brother and sister.
"Nothing!" The little sister said kindly to her brother.
My little brother seems to be stunned, and I seem to hear his voice: "What's wrong with this sister?"
The elder sister asked the younger brother again.
The little brother finally spoke: "Nothing, nothing, you were kicked by me. Does your leg still hurt? " "I'm fine!"
After class, my little sister and brother slowly walked to the B teaching building.
Tolerance and forbearance are really great! Can make the injured people care about others! It's incredible! I see! What a man must have is tolerance and forbearance, because with them, life will become more meaningful and happier! Let us all have a pure heart!
