The first volume of the fourth grade unit composition 1 1, exercise requirements
Write down the findings in the form of a diary.
Second, the method of guidance.
As long as we observe carefully, we will find that many things around us have interesting phenomena. For example, fish sleep with their eyes open; As soon as we touched the mimosa, it closed its leaves and seemed very shy. In this exercise, let's write down our observations in the form of a diary. Diary belongs to a kind of practical writing and has a certain format:
On the first line, write down the year, month, day, week and weather conditions. Usually written in the middle of the first line.
The second line, start writing the text.
Diary generally does not write a title, but the first time you write a diary, you can add a title, so you can write around a center.
When writing an observation diary, besides paying attention to the format of the diary, you should also pay attention to the following points:
1. Choose what you are most interested in and observe it in a certain order. For example, when observing the appearance of a thing, you can observe the whole first and then the part; You can observe the development of a thing in chronological order. Observe carefully and accurately.
2. Complete the observation process according to the observation order. I want to write what I am most interested in, and I want to write specifically.
3. When writing, you should highlight the discovery in observation and write clearly what inspiration or feeling it brings to you.
A friend came to my house for a party and saw a big fish tank with few fish in it. She said that someone sent her some fish, but several of them died because the fish tank was too small and there was no oxygen washing equipment. She wanted to give me the remaining three fish.
I put the small fish in the fish tank. Maybe they look very novel and excited in the new home and environment. I saw them swinging their dexterous tails and swimming lightly up and down, left and right, as if observing the familiar environment. At this time, they seemed to find something and stared at the original big fish in my house. Then swim quickly next to it, just like treating a long-lost relative, hitting the back of the chair with your head and hitting a big fish. The big fish also enjoy this enthusiasm, and it is very warm to pull a few aquatic plants for them from time to time.
Oh! I found that these fish are all from koi fish, so they are a family. Look at other different kinds of fish and the new koi fish. It seems that nothing happened between them and they didn't interfere with each other. Do you know any strangers?
In order to verify my judgment, I reached into the water and caught the big fish. Then a miracle happened. I saw these three little fish bite my hand with their mouths or tails. Although it didn't hurt, I already felt the blow of their anger. It's incredible.
I don't understand. People don't attack me, I don't attack. If people attack me, I will attack. What humans show actually happens to animals. Maybe it's an instinct given by nature!
My mother brought back some fish from her colleagues and kept them in a round fish tank on the sideboard. A fish is black with white stripes; There are two small gray fish; There are also two fish, both of which are beautiful pink.
I like these lovely little fish very much. Say hello to them every morning; Every night, I have a good night with them. When I eat, I will watch them lose my mind.
But one morning, at dinner, I looked at the little fish. Suddenly, I was surprised to find that the fish grew up, especially the snakehead fish, which occupied almost one third of the fish tank. I thought strangely, "How did this fish grow so fast and so big?" But when I look at the fish in the fish tank, they become as small as before.
This discovery aroused my strong curiosity. I am determined to find out the answer.
I immediately searched the internet and finally found the answer.
A round fish tank can be approximately regarded as a convex lens, which is the magnifying glass effect. The round fish tank and water form a "convex lens". When a fish swims by, it is equivalent to being within a focal length. According to the law of convex lens imaging (when u < f, an enlarged virtual image is established), what human eyes see is an enlarged virtual image. Besides, from the plane, it looks very comfortable; Round and curved eyes will get tired if you look at them for a long time.
Oh, I see.
I hurried to my parents and told them about it. Mom's eyes widened: "Really? I haven't found this before. " Dad also repeatedly praised me for observing more and thinking more.
There is science everywhere in life. As long as you can find problems and think about them, you will definitely say "?" Become "!" .
Yesterday, after an hour's journey, we arrived at the beautiful Tongxiang Wuzhen, where the scenery is beautiful and the night scene is brightly lit.
Enter the Zhaxi scenic spot, with blue sky and clear water, and ships coming and going on the river. A simple and beautiful scene like an ink painting is presented to me. Wuzhen's alleys are long and narrow, and most of the houses are typical Jiangnan white walls and black tiles. On both sides of the river are old houses carved with beams and painted buildings, with antique reflections in the water.
Along the way, I saw many people carrying small lanterns of different colors and shapes. I really want one, so let my mother help me find out where I bought it. After I found it, my mother bought me a pink one with hollow patterns. So cute!
Then, we came to the outside of the restaurant, where there was a big waterwheel, creaking and turning, which was very old-fashioned!
The bridge in Wuzhen consists of long and wide stone slabs, which are generally arched and engraved with patterns. There are bridges of various shapes and sizes in Wuzhen, the most famous of which is Shuang Yuan Bridge. It is said that it is customary for men and women to walk on Shuangqiao Bridge. If you walk on the bridge once, you have to walk left and right, so you can walk right and left. What a unique flavor!
Sighing that time waits for no one, it's already ten o'clock at night, and it's time for us to go home. On the way back, I saw the colorful lights reflected in the water. The beautiful Wuzhen really made me linger back and forth. I have fallen in love with this place deeply!
Everyone has their own unique world. Do you want to know my little world?
I have three small worlds!
My little world is my bedroom: in the center of the room is a big bed 2 meters long and 1.5 meters wide; There are two "little yellow pigs" and "little red pigs" on the bed. They are chubby and cute. They accompany me to have a good sleep every night. I like them very much! There is a bedside table and wardrobe next to the big bed, where the four seasons clothes arranged by my mother are neatly placed.
My other little world is my study: the study is a four-story bookshelf against the wall, on which many famous Chinese and foreign books are neatly placed, such as One Hundred Thousand Why, Romance of the Three Kingdoms, The Wizard of Oz, Ci Hai and Globe. Next to the bookshelf is a computer, which is usually used to look up information, and sometimes you can use it to play music when you are tired, so as to eliminate the fatigue of the day. On the wall of the study, there is also a calligraphy work that reads "Self-improvement". It won the second prize in this year's China Newspaper primary school calligraphy competition!
I still have a small world, that is, the big desk in the living room: desk lamps, Mickey Mouse clocks, pencil sharpeners, pen containers, reference books and other items are neatly placed on the desk; There is also a photo of my mother and I in the Great Hall of the People in Beijing on the desk. I watch my homework in the soft light after school every day and swim happily in the ocean of knowledge. It was really fun!
These are my three little worlds. Welcome children to my home!
Today, as usual, I turned off the light and got ready for bed. When I lay in bed and closed my eyes, the first time I slept alone six years ago came to my mind.
On this day, my mother took me to the crib I bought a few days ago. I asked doubtfully, "Mom, did you bring me here to be a club?" "Mom smiled and said," This is your bed. Mom specially laid a Snoopy-patterned sheet for you! Do you like it? You can sleep here alone today. " I climbed into bed and said happily, "Really, that's great! "But in the evening, I immediately changed my mind. My mother tucked me in and turned off the light. I saw that the room was empty and I was alone. I closed my eyes, and Otmali's nightmare appeared in my mind. He specializes in catching children. So, I opened my eyes and ran to my mother's room, crying and saying, "Mom, shall I sleep with you first?" "I will sleep alone tomorrow, and I think the nightmare will take me away." I cried even harder. My mother touched my head and said earnestly, "Don't be afraid. Everything in the incus is fake, and the incus are also performed by others. Don't be afraid. You are a brave baby, aren't you? " I dried my tears and nodded reluctantly. So, I opened the door of my room again, lying on the bed carefully, chanting in my heart: monsters are all fake, I am not afraid, I am a brave boy. Finally, I fell asleep peacefully. Later, I never cried because I slept alone.
I overcame my fear of sleeping alone.
After reading this report, I deeply feel that these tourists are so uncivilized that they not only don't protect the environment, but also litter. Think about it, if everyone throws a plastic bag, then the Great Wall will become a garbage dump. Those villagers actually set up ladders on the Great Wall and charged at will, which brought inconvenience to tourists. And those real estate developers, the Great Wall used to be beautiful, but after they built buildings that were not in harmony with the Great Wall, the Great Wall became ugly. Do you know that tourists litter, villagers collect fees at random, and real estate developers build buildings indiscriminately? Your actions will make the Great Wall destroy faster.
I put forward some suggestions to protect the Great Wall: First, don't litter. Second, don't scribble on the stone. Third, farmers should not use the stones of the Great Wall to build their own walls.
Besides the Great Wall, the Leifeng Pagoda was also damaged. There is a long escalator in front of the newly-built Leifeng Tower, and a transparent elevator for people to lift is installed in the tower. But after the construction workers did this, the Leifeng Tower seems to have become a modern thing.
In order to prevent the cultural relics from being destroyed again, you can write a proposal to the museum, let the administrator strictly manage the cultural relics, and don't let the cultural relics dealers do bad things. You can send out some leaflets to tell everyone to cherish cultural relics. You can send out some leaflets that cherish cultural relics in the newspaper.
Let's join hands to protect national cultural relics!
Near my home, there is a locust tree of the same size, and a spider lives in the middle of the tree. It's hard to weave a net.
One day, a strong wind blew. The strong wind messed up the branches and tore the cobwebs. Just when I was worried, I found a miracle. The spider struggled to climb from the trunk to its original place, and then resumed its old job from the broken silk. Round after round, one root after another, in this way, it keeps going back and forth, working hard in a circle countless times bigger than it.
However, it happened that God opposed it. The spider just finished weaving several times and saw a web slowly forming, but a thunderstorm followed. Raindrops are as big as soybeans, and I desperately hit the internet. Suddenly, the net that had just been partially repaired became fragmented and tattered.
After these two heavy blows, it is even more difficult to remedy. However, the spider was not discouraged. As soon as the rain stopped, it appeared on those broken nets again, still so focused. I think it continues to circle on the original net, making the net woven more firmly. What a clever spider! It knows that in the days to come, this net will definitely encounter more storms.
I watched and was suddenly impressed by the indomitable spirit of that spider. In the face of difficulties, spiders can persist and weave broken nets again and again, and they weave more firmly every time. How tenacious.
Facing the spider's unyielding, I can't help thinking to myself: shouldn't we be like it? We will also encounter all kinds of difficulties in life. If we can do everything with such perseverance and perseverance as spiders, will we still worry that we can't do it? The little spider has brought us such great enlightenment. I really appreciate such a strange afternoon and the strange experience I met.
The campus is full of energy and passion. In this warm campus, we study happily and grow up healthily.
Although there are many beautiful places on campus, I still like the plant belt, the crystallization of nature.
The azaleas in the plant belt are cut into delicate flower baskets by the superb hands of gardeners. They are in full bloom against the spring breeze.
From a distance, the whole azalea is like a burning torch. Up close, cuckoo birds are one after another, just like the little red corner. Some just spread one or two delicate petals, and some are fully open, and they are in full bloom and red as fire. Some are still full of flowers, budding and bursting.
Every time I step into the campus in the morning, I see the tall and straight coconut trees in the plant belt. Its branches are so thick and straight, and its leaves are so lush, spreading around like a huge green umbrella, guarding our school.
The leaves of cycads are like saws with teeth on both sides, and like flat and sharp needles. After the leaves grow out of the middle, they will slowly expand their territory-this is a move by the Cycas to protect themselves.
There is also a jade unicorn, unlike the majestic unicorn, like a peacock spreading its wings; Its thorns are all distributed on the stem block one by one, as if telling passers-by: don't look, don't move! How interesting!
This is our plant belt. In my eyes, this plant belt is always the most beautiful.
Unit 10 in the first volume of grade four. Tonight, I ate at my brother's house. After dinner, I told my mother that I wanted to go to the seaside. Mother said, "Go. We haven't been to the seaside this summer. Let's go together! " "
So, I, my mother, my brother, my sister and my second aunt went to the seaside together. On the way, I said to my brother, "Wait a minute, let's go to the seaside to catch crabs." My brother never caught crabs, so he agreed happily. When we arrived at the seaside square, we ran to many big rocks by the sea, but at that intersection, my mother and I suddenly met my aunt and sister (my mother's colleague and her daughter). They haven't seen each other for a long time, so we chatted there and I played with my sister. First we ran around on the gravel road, shouting "massage your feet!" " ! Massage your feet! "Then build a house with stones, mash the grass and leaves with stones and cook them together. Later, we ran down the high slope with stones and asked my aunt and mother to take pictures of us. At this time, I can't see my brother at all. My brother doesn't know them. Where did my brother go? I had a good time, so I didn't think about it.
It's getting dark, and my mother and aunt say, "Well, we're going back to the village!" " "My sister and I had a good time, but I didn't want to. At this moment, I suddenly heard my brother calling me. Looking back, I found that my brother had brought a lot of crabs. It turns out that my brother and sister have gone to catch crabs as planned. So the seven of us went back together and talked about my brother catching crabs while walking, and my sister and I were happy again.
Playing at the seaside, although I didn't catch crabs with my brother today, I still had a good time; Although my brother didn't play with us, he had a good time.
It's fun to play at the seaside!
Unit Composition 65438+20xx 1 Grade Four Book One In a poor village, there lived a Miao grandmother, whom everyone affectionately called Grandma Wang. Grandma Wang is white-haired and wrinkled, and her children are working outside, and there is no news. She is helpless, has no relatives and has no reason. Neighbor Xiaolan is a caring little girl of Han nationality. Knowing that grandma is in trouble, I visit grandma Wang every day. She is ready to help others and will help Grandma Wang do some housework within her power.
With the passage of time, Grandma Wang is getting older and older, and her physical movements are more inconvenient, but she has no relatives and no dependence. When winter came, Grandma Wang took out the clothes she wanted to change and washed a thick cotton-padded jacket under the north wind. The north wind blows grandma Wang's face like a knife in her face, which is very uncomfortable. While washing clothes, Grandma Wang recalled the children's past and looked at herself. Grandma Wang couldn't help crying. Just then, Xiaolan came to visit Grandma Wang.
She saw grandma Wang stop to catch her breath for a while, then her back was bad again, and she wanted to hit her ... Xiaolan went over without saying anything, took the washbasin and sat down. She rolled up her trouser legs, rolled up her cuffs, put down the washbasin, picked up the washboard, and rubbed the clothes on the washboard repeatedly until they were clean. After washing for a while, Xiaolan gradually felt that her hands were very sour, and water droplets splashed on Xiaolan's skirt and trouser legs, making her feel cold.
Grandma Wang saw that the clothes were ready, so she ran up to touch Xiaolan's smooth face. Grandma Wang's hands are covered with cocoons, but they are warm. "You are really closer than my relatives!"
There are true feelings everywhere in the world, and true feelings always warm people's hearts. Xiaolan and Grandma Wang are not a family, but they are better than their relatives!
The grass is not as tall and straight as pine trees, nor as gorgeous as peony, but I love the unknown grass.
Spring is coming. Whenever I come to the small lawn, I will "fly" on the grass, watching the grass turning green and smelling its refreshing fragrance.
The breeze blew, and the grass danced happily, stretched its arms and swayed from side to side.
I remember once, I was walking on the lawn in the afternoon. I squatted down slowly, stroking the grass gently and smelling the fragrance. At this time, a few muffled thunder sounded in the distance. I had to run into the small pavilion, and suddenly it began to rain cats and dogs. After a while, the rain finally stopped. When I look at the grass, I see that it used to be green, but now it has become Wang Yang. After a while, the rain seeped into the soil and the grass stood tenaciously. Crystal beads on the grass sparkled in the sun.
Every time I see grass, it gives me countless inspirations. Grass is so fearless and tenacious, embellishing this beautiful spring with its own wisdom.
Grass, ordinary, quiet and inconspicuous. Not charming or fragrant. For the sky, it has no flattery; To the ground, it is not arrogant. He's an ordinary person. Life is unknown, death is not a decline, but a continuation from generation to generation ... let us feel relaxed and happy!
I love you, Grass!
One night, my mother and I went to Wal-Mart to buy toys.
When I walked into the toy house, I was immediately moved by the warmth there. The white wall is painted light green, and there are many big pillows on the shelf, including strawberries, Doraemons and rainbows. There is also a shelf full of plush toys, or characters from different cartoons! There is a table dedicated to small ornaments, so many pendants dazzle me.
Suddenly, my eyes were attracted by a crystal ball: a flesh-colored rabbit, wearing a red sweater and a blue scarf, leaned back slightly and was pushing a big bamboo basket. The bamboo basket is covered with a layer of pink cloth and contains a big crystal ball. There is a string of apples in the crystal ball, and there is a "for you" among the apples. It's beautiful! I secretly admire this crystal ball in my heart. The workmanship is so exquisite that even the fluff on the rabbit can be seen clearly. I fell in love with it immediately and begged my mother to buy it. My mother happily agreed.
Wow! There are so many exquisite toys here! I immediately found a lovely bear with a big head, round ears and a red button sewn on his chest. The cutest thing is its face! Although the bald head is cute, it is far from its pink face. White with pink fur, black eyes like two black gems embedded in the face, and a white nose and a doodle mouth! I accidentally touched its face, only to find that its face will move! Oh! It turns out that all I saw just now was its blindfold!
Today, we went home happily. Of course, I also got a lot of fun toys!
14, after school, we will go to the central garden next to the kindergarten, where the scenery is pleasant and it is the first choice for us to play when we were young.
The scenery of the central garden in the four seasons makes people linger. This is a paradise surrounded by small forests. There is a peach tree forest on the outermost layer. On the morning of early spring, the first ray of the sun shines on the green leaves of peach trees, which looks very comfortable. At night, the neon lights wrapped around the trees lit up, like thousands of fireflies flying in the night sky of Qian Qian, and like countless half-bright and half-dark stars flashing. In mid-spring, peach blossoms danced in fluffy skirts. I don't know if they knocked over the perfume bottle. When they get close, they will feel a delicious smell. Summer is coming, pink peaches are hanging on peach trees, like the smiling faces of little dolls, which makes people fondle them.
We have a lot of activities there! My favorite thing is hide and seek. There is a big stone altar in the center of the central garden. There is a small stone altar above each stone altar, and there are intermittent low walls next to each stone altar, which is very suitable for hiding.
It's also our secret base. The road to the secret base is very narrow, only children can enter, and adults will get stuck when they enter.
It's really a place that makes people linger and full of memories!
Students, learning is inseparable from writing. We have to bring ballpoint pens, fountain pens, crayons and pencils every day ... These pens are indispensable and make the pencil case heavy, but the pens I designed can solve these problems!
Although its appearance is no different from the current pen, there are many "organs" in it! It has four buttons with different colors: the first button is pink, which allows the pen to change colors randomly. The second button is purple, which can turn pens into ballpoint pens, fountain pens, crayons and pencils ... so you don't have to take a heavy pencil box to school. Students will ask, "Will such a good pen be stolen?" Hey hey! This is the usage of the third yellow button I want to talk about. When you use it, this multifunctional pen has memorized your fingerprints. If it is pressed by someone who is not you, it will automatically call the police, and other functions will be invalid. The fourth button is red. If there is a power failure at home, you can press this button, and a small light bulb will pop up at the top of it, so you can do your homework as usual!
How's it going? Do you like my pen? I firmly believe that one day, with the progress of high-tech technology, this pen will be developed.
