Diary fourth grade composition

In daily study, work or life, everyone has written a composition, which can be divided into narrative, explanatory, practical and argumentative according to different genres. So how to write a general composition? The following are 10 compositions in my fourth grade diary for your reference, hoping to help friends in need.

I found my mother looking for something in my room yesterday. At first, I didn't care. Later, I found my mother looking for a diary in her room. After learning the news, I was extremely anxious, because there were many secrets of myself in my diary, and I didn't want others to see them, including my mother. Where should I hide my diary before my mother finds out? In the library bag? No, hidden in the drawer? Then I can't keep up. Hey, where should I hide? That's right, under the bed. Ha ha! Now mom can't find it.

After hiding, I went out to eat. At the dinner table, I looked at my mother's listlessness and sighed again and again. I was secretly pleased, thinking: Hum! Who wants you to read my diary! Suddenly, my mother looked at me. He said to me, "Son, where did you hide your diary?" Huh? It is too dark to see clearly. What should I say? At that time, I realized that my diary was going to suffer a tragic fate. I stammered, "Yes, under the bed." No sooner had I finished than my mother ran in and put her hand under the bed: "Here it is." Mother let out a cry of surprise, "ah! My poor diary! " I shook my head and said.

Later, I learned that my mother asked me to keep a diary every day to read it. I can't help it I know my mother is good for me, but my mother should also consider my feelings! At this time, I want to say to my mother, no, to my parents in China: "Please don't read our pupils' diaries. We students also have students' secrets. Please don't peek at our little secret. "

A few days ago, the teacher asked us to go home to soak beans and observe the daily changes of beans.

I grabbed a handful of beans from the refrigerator, detected them as bad, and put them in a cup and soaked them in water.

When I changed the water the next day, I found that the beans were swollen, like children who drank enough water. There are some small wrinkles around the radicle.

On the third day, a small bag appeared on the radicle, and the wrinkles around it disappeared and became the head of a little fairy. Under the guidance of my mother, I poured out the water, covered it with a 10% towel and sprinkled some water on it. According to my mother, the towel is covered to keep it moist. If beans are soaked in water for a long time, they will rot easily. After listening to my mother's words, I thought: there is so much knowledge in soaking beans.

After two days, a small bud of one or two millimeters grew on the radicle. Buds are very small, almost as thick as nails, and they get thinner as they go up.

Two days later, palmers grew into four or five millimeters of fine needles, and the dark yellow clothes turned into light yellow. Yale is as curved and beautiful as the moon. My mother told me: "This kind of bean sprouts can be fried and eaten, just like the bean sprouts sold in the market. However, it was reported on the news two days ago that there was something in the bean sprouts sold outside that made people eat badly. You see, the bean sprouts you made are safe to eat! "

The name hamster comes from German, which means storage. Some people are called hamsters, hamsters or hamsters because they know how to hide food in cheek pouches on both sides of their cheeks. Primates such as macaques, rodents, squirrels and squirrels also have such a special pouch structure on both sides of their mouths, namely cheek pouches. Spit out the food in the cheek pouch, store it or eat it in a safe place, which is one of the habits of hamsters.

When feeding hamsters on weekdays, you must not lack energy, because it will feel very uneasy without food, so it is best not to leave its food basin empty. I don't know if you have noticed, but the mouse's cheeks are full of things. Very cute, this is not a very fun thing, maybe something big will happen, especially in the hot summer! As pet owners, we should always pay attention to whether hamster cheek pouches are completed. Hamster cheek pouch has limited capacity. If you haven't finished eating, please don't give any more. If full of food for a long time, the food stinks in the cheek pouch, which is prone to redness and swelling of the cheek pouch, leading to inflammation of the cheek pouch.

During the time when the prince and Xiaohua came to my house, they have been extremely rich luxury goods. There are plenty of foods every day, but they still can't change their living habits of hiding food in their mouths, nests and cages. One day, I casually gave the prince a sunflower seed, which was very small and shriveled, probably half a seed shell after screening. When the prince saw this melon seed, he was not as excited as he usually saw high-quality sunflower seeds. Instead, he stood there and looked, waiting for a while. Then it stood up straight and quickly pinched its cheek with its two front paws. As it squeezed, a lot of food fell out of his mouth. After this action, he glanced at me sideways, as if to show off, and said, "Look! The inventory in my mouth is more than what you fed me, and it is bigger! " Then it lowered its head and squatted on the ground, put the spit food and melon seeds back in its mouth, turned around and left!

After a long period of observation, I finally understood that their original behavior was not to show off at all. They hide food in their mouths layer by layer. Whenever they see new food, they have to rearrange the order of storage, so there is a scene of vomiting first and then swallowing. Sometimes the width of the food stored in its cheek pouch can reach twice the normal body width, so when it passes through a narrow passage, it can only barely spit out a part of the food to pass.

Diary composition 4 "microorganism", a word that was strange to me before, but in this science class, I got to know it again. Under the patient explanation of Teacher Qian, I consolidated my understanding of it!

Microorganisms are such interesting creatures. They are a large group of organisms, including bacteria, viruses, fungi, some small protozoa and microalgae. Although they are small, they are closely related to human life. Covers a variety of beneficial and harmful, covering health, food, medicine, industry and agriculture, environmental protection and other fields.

In this class, the teacher also showed us what kind of cells will appear on the onion skin under the microscope. Before that, let's learn what a microscope is! It is an instrument that produces magnified images of objects by physical methods. It was first invented in the late 6th century of/kloc-0, and has a history of more than 400 years. Now, it has become an extremely important scientific instrument, widely used in biology, chemistry, physics, metallurgy, brewing and other scientific research activities, and has made great and outstanding contributions to human development! Anyway, let's have a look at our onion skins! I saw the onion skin turn into a net under the microscope, neatly. We also saw green onions and garlic. ...

This science class is very important to me, because it really lets me know what microorganisms and cells are!

Fourth grade diary composition 5 20xx year x month x sunny

Today is the solstice of winter, with the shortest day and the longest night.

Grandma said that according to the custom in my hometown, if I don't eat jiaozi on the solstice in winter, my ears will freeze. I woke up earlier yesterday morning. I go to bed at eleven noon. When I woke up, my grandmother had finished eating jiaozi. Get up and play for a while, and eat four big jiaozi in one breath. After eating these four big jiaozi (the jiaozi my mother packed yesterday was bigger, even bigger than the steamed buns sold outside! Hey hey)! It seems that I'm not finished yet, but my mother is afraid that I will eat too much at a time and spoil it. I have no food!

At noon, grandma and mom packed a lot of jiaozi, which were frozen in the refrigerator! At noon, my mother saw that I liked jiaozi very much, so she made me some jiaozi in the evening, and I ate nearly four more! I also ate some noodles!

But there has never been such a good phenomenon! Mom said maybe I bought jiaozi in the store before, but it's not as delicious as my own jiaozi! From then on, we often make jiaozi for ourselves to eat!

Children, I ate well, didn't I? Everyone should learn from me in the future! Only by eating more, the health of family members will be great! Come on, everybody

Diary composition article 6 "Oh, I don't want to run exercises-"Well, we're going to run exercises again!

On Friday morning, we ran and practiced as usual, and the students were as reluctant as before! Of course, so do i. I don't really want to run and exercise! Although that thing can strengthen the body and is really good for us, it is too tired! I don't want to.

The familiar music starts again and starts running! During the running, I kept my mouth open! Otherwise, you can't breathe out at all. I just lost a little heart! "Whoosh, whoosh-"Just after running a lap, I was already stingy, and I couldn't speak at all, and my legs were not willing to take off! If I don't keep up, I will be trampled to pieces, alas! I don't want to run again if I think about it. However, we also lack exercise. If we often run in the morning, we won't find it difficult. Zhang Fei eats bean sprouts instead-a piece of cake! This is the gap, you still have to exercise and keep fit!

Whew, I finally finished running, so tired! When I walk to the classroom, I can still hear a strong heartbeat! "Burst, burst-",but also feel that breathing is not smooth, a little difficult, very uncomfortable, I feel really uncomfortable! Hey, I really don't want to run, but I'd better come back. The school makes us do exercises for our own good. Let's keep healthy. Why not?

Looks like more exercise!

Today, I followed my mother to the market to buy food. Mom said, "I will test you today. Will you buy a dish you like?" My mother gave me 20 yuan to watch my performance. "Make sure the task is completed." I said confidently. So, I walked and watched, and came to the vegetable area. At this moment, I saw an aunt selling white and tender fresh mushrooms. I think: the leftovers at home can be cooked with mushrooms. So, I asked the aunt who sells vegetables: "Aunt, how much is a catty of mushrooms?" Aunt smiled and said to me, "Kid, this mushroom costs 7 yuan a catty. How many Jin do you want to buy? " "Aunt, I only need to buy half a catty." I think: 7 divided by 2 equals 3. 5 yuan, 20 MINUS 3. 5 equals 16. 5 yuan. I thought about it and gave my aunt a note of money from 20 yuan, reminding her to call me at 16. 5 yuan. I went to the meat department again and saw an uncle selling meat, so I asked, "Uncle, how much is a catty of meat?" "10 yuan a catty." "I want to buy a catty of this." On second thought: 16. 5 minus 10 equals 6. 5 yuan. I play 16. 10 yuan in 5 yuan was given to this uncle.

When I came out of the market, my mother saw that I had both meat and vegetarian dishes. When I was in 5 yuan, I smiled and said to me, "Learn to buy food!"

Through this test, I feel that there are many mysteries of mathematics hidden in our lives, and the ability to learn mathematics is really important. Besides, we should not be proud. We should study hard and master more math skills in order to apply what we have learned and solve the problems around us.

Diary Grade 4 Composition 8 20xx April 12 It's sunny on Tuesday.

When the young master and mother put "me" and "my" brothers and sisters in a white basin, "I" knew that I was going to start a new journey, and my heart was full of excitement.

At first, the young master asked me to take a cold bath, which was really comfortable. Then let me soak in a small amount of water to cover me and my brothers and sisters. After a day and a night in it, "I" was really uncomfortable! Why? Because it's too hot. Ah! Heaven and earth! Why was "I" so unlucky that I was caught swimming? And it is hot swimming!

It's really hot. "I" and my brothers and sisters almost drank a lot of water, and quickly started the game to undress. Some people take off their clothes with a bang and feel relaxed. Some are half-covered and half-covered, which is much more comfortable; Others have inflated themselves and spent a lot of effort to get what they want.

Look, young master is coming with a camera. Do you want to take a picture of me? Great! I can finally see my true colors.

Really? Why is "I" white and tender? I have a small horn. Is this ... this ... is this still me? Let's have a look! How did this happen?

We took off our clothes in the game.

Look at the results of my first day of travel! Our horns are about 2 cm long.

It will be fine on Wednesday, April 13, 20xx.

The young master and his mother came again and gave me a cold bath. Almost washed all my clothes away. Oh, I'm sorry. I just stayed naked in the washbasin.

Young master brought the camera again. Why? Have I changed again?

The young master also brought a ruler. Oh, why did you take out "I" and put it gently on the table next to the ruler?

"Mom, look, it's growing again, almost 3 cm." The young master said loudly.

The next day, as a result of my trip, the trumpet grew to 3 cm long.

It will be fine on Thursday, April14th of 20xx.

Such a trip is really too difficult for me. Every day is the most comfortable time to take a cold bath, and then there is a long wait.

We are all very tired. The water in the body is getting less and less, but the small horns are getting longer and longer. Dragging a tired body, I can't walk.

"What do you think, young master?" My brother said.

"One day, we can't stand such a trip." My sisters said.

"Shall we run away?"

"How to run? In this way, do our parents still recognize me? " Everyone was lost in thought.

At this time, the young master came to me excitedly. I suddenly felt that it would be more difficult for me to move my body again, and my head became very, very heavy. The young master carefully invited "me" and the two we just talked about.

"Kaka", the flash flashed. Wow, the horns on my head are getting longer and bigger, alas! If I had hands, I really want to pick up a special kitchen knife and cut off that heavy horn with a click. Then "I" can return to the previous state, although I have no clothes!

That was the result of the third day's trip. Actually, it's "me"

Naked, the young master put on a camera bag.

At this time, the trumpet is about 5 cm long.

It will be fine on Friday, April 15, 20xx.

Ha ha! The young master said, today we can be liberated. In order to leave me a beautiful moment, I took a photo specially. Come and have a look!

Haha, I'm going to show off!

This is me! That horn is so long that new buds have grown on the other side of my body. The angle is 6 cm long.

"Mom, if you flatten the bean sprouts, measure them carefully. They are about 7 cm long! " Said the little master.

What? Did you hear "I" correctly? Why is it called "small bean sprouts"? It turns out that the young master let me travel for so many days just to sprout "me"!

Oh, no big deal. The last journey of "we" was actually put into a boiling pot by the mother of the young master. Is this the reason? After suffering these days, I was finally scalded a few times, which made us dizzy and finally lost consciousness.

"I" loudly announced that such a trip was terrible!

The destination of my trip is this plate. Oh, no, it's the little master's stomach, right?

Self-evaluation: I didn't update my blog these days just to write this observation diary. Write a little a day and revise a little. It's wonderful to see many bloggers telling stories about the growth of bean sprouts! So I also want to write it differently.

In my opinion, nothing is more vivid than the dialogue between bean sprouts. I revised it with my mother. There are still some shortcomings, please ask bloggers to give more valuable advice.

Mom's words: In order to encourage children to keep observation diaries, we observed the whole process of bean sprouts growth with our children. The only regret is that those so-called "green clothes" have not been photographed, leaving children with less room for imagination.

At first, the children wrote very simply. I asked the children to add some dialogue descriptions and "heart" descriptions. I am also a layman in writing. Hehe, please give me some advice from bloggers!

Early this morning, I vaguely heard my mother calling, "Jung, get up quickly, your little vegetables are sprouting!" " "

I got out of bed and ran to the balcony. "Wow, it really sprouted, and there are so many more!" "

I cried in surprise.

After breakfast, I remembered my "little life" again and went to observe it. I looked at it carefully, hoping to find something that suddenly occurred to me: the weather was fine a few days ago and it didn't germinate. Why do you want to sprout on this rainy day today? I immediately looked up the magical plant world and finally found the answer. It turns out that many plants like listening to music, such as small vegetables. What they like best is the sound of running water. It's raining today, and there is running water. Small green vegetables and rape probably broke ground listening to this wonderful "music".

After observing the plant, I feel that its soil is a little yellow, so I need to water it. Just picking up the kettle and preparing to water it, my mother grabbed the kettle and said, "It's raining today, and the tide is very high. If you water it, it can't absorb it, so its roots will rot. " That was close!

Today I learned a new knowledge: in rainy and humid weather, you can't water plants too much.

At noon, we are sleepy, and so are the little vegetables. They closed two leaves, as if they closed their eyes, and its stem hung down, as if to say, "I'm sleepy, I'm going to sleep!" " "

With that, he bowed his head and went to bed.

I hope the small vegetables I grow can grow into strong big vegetables with light green stems, full hearts and big leaves, so that we can enjoy its delicious food!

Diary composition for the fourth grade 10 This morning, we had an interesting lesson in Olympic Mathematics. "Ding ..." The teacher came into the classroom with a big smile on her face. The classroom suddenly became quiet. The teacher said to us, "Let me test you a question first: the quotient obtained by dividing two integers is 12, the remainder is 26, and the sum of dividend, divisor and quotient remainder is equal to 454. What is the divisor? " I read it again, two ... "... after I got the question, I thought: How can I find the divisor of this question without any divisor? But recalling that teachers often say that drawing line segments is a magic weapon to solve application problems. Why don't I try? So, I began to draw: first take the divisor as a multiple, the dividend is 26 times more than the divisor, and then draw the quotient and the remainder. Oh, it turned out to be a matter of doubling. The formula is: (454-12-26) ÷ (12+1) = 390 ÷13 = 30.

I think: we have learned the method of calculating with X. Let me write out the formula of the text first. Divider × quotient+remainder+divisor+quotient+remainder =454, then let the divisor be X, and the formula is: x×12+26+x+12+26 = 454. I subtract 12 and 26 first, then I leave the dividend and divisor, and then because there is a remainder in the dividend. I want to subtract 26, so the dividend is equal to 12. The divisor is 30. Expressed by the formula, it is: x×12+26+x+26+12 = 454.

Today is mom's birthday. Mom went to work in the morning and didn't come back until evening. At 8 o'clock in the evening, my mother came back. While eating the cake, my mother said to me, "Mom will test you. Will you eat a piece of cake if you get it right? " I said "no problem" and began to answer questions.

Mom asked the first question: Mom is 36 years old, and you are 10 years old. How old is mom? Grandma is six times your age. How old is grandma this year? I quickly worked out the result with my mouth. I said, "My mother is 26 years older than me, and my grandmother is 60 years old this year. It's too simple, my cake will be eaten. " Mom smiled and said, "Are you proud?" One more question: Xiaoming is 8 years old and his father is 40 years old. In a few years, will his father be twice as old as Xiaoming? Now I'm stupid, thinking hard, as if my cake can't be eaten. My mother said, "What's the matter?" "Let me think about it. I can't figure it out. I don't eat cake. "

After a while, I thought of a stupid way. I can find out their ages. A year has passed, and both Dad and Xiaoming are one year older. Finally, I figured it out. After 24 years, Dad is just twice as old as Xiaoming. I told my mother the idea. My mother said there was an easier way, and then she told me. Just subtract Xiao Ming's age from his father's age, and a few years later it will be Xiao Ming's age, that is, 32 years, and then 32-8 = 24 years will be the past years. It suddenly dawned on me that it could be so simple.

Mom said: it's good to find a way to get the result by yourself. As a reward, I eat cake. I am both happy and embarrassed. I can't be proud in the future, and children should not learn from me.

Do you know how to solve the formula 9 1+92+93+94+95+96+97? Maybe you think there are only one or two, so let me tell you that there are three solutions to this problem.

Second, because these numbers are close to 100, we regard these seven numbers as the sum of 100, so we add 9+8+7+6+5+4+3, and finally subtract the sum of these numbers from 700.

The third type: among these seven consecutive natural numbers, 94 is in the middle, the first number 9 1 is 6 less than the last number 97, and then 6 is divided equally to 9 1, so 9 1 and 97 become two 94. Similarly, 92 and 96, 93 and 95 can all become 94, so seven numbers become seven 94.

Let's just count the exercise books. How long will it take us to count 100 exercise books? 1 serving, 2 serving, 3 serving ... 100 serving, which takes about 1 10 second. There are 1000 exercise books, 10000 exercise books, 100000 exercise books ...1000000 exercise books? Just do the math and you'll know how big 100 million is.

Calculate, hundreds of millions of exercise books will take about 1 100000000 seconds. Imagine, how many points do you need for hundreds of millions of exercise books? How long? How many days? How many years/about 183333 minutes, 30556 hours, 1273 days, 3 years! I really don't know, hundreds of millions of homework would have taken three years!
