Our holiday composition is 300 words.

Unconsciously, a happy and fulfilling winter vacation has passed. During the winter vacation, although the weather was hot and cold, I still had a good time, because too many interesting and happy things happened, which added a lot of color to this winter vacation. Among them, I think the most unforgettable day is the day when I worked part-time at home.

On that day, my parents went out and gave me a task: just like a part-time job, I cleaned up all the places in my house, washed dishes and prepared dinner. Although I am usually the little princess at home, what's so difficult about it? I will keep my word.

I want to wash the dishes first. I put the "white cat" detergent in the water, let it almost melt, and then put the bowl in. Then, I picked up the rag again and wiped the bowl carefully. Gradually, sparkling bubbles appeared in the water.

The 300-word time of our primary school composition is like an endless river, passing by people in a hurry and quietly. Unconsciously, a memorable 20 years hurried away, ushered in a new year, and began another journey for people.

The new year is coming, and the streets, supermarkets and vegetable markets are crowded with people. Some buy food and go home to cook, and some buy gifts to visit relatives and friends ... all celebrating the arrival of the New Year.

On the morning of New Year's Day, I opened my eyes with firecrackers. Open the calendar, start a new year and start a wonderful story. I lay in bed thinking about the past year. I have sweat, happiness, sadness and gratitude. It all happened as if it were right in front of my eyes.

On the first day of 20**, I did many meaningful things. I learned to cook; Helping my mother wash clothes and tidy the room … These things are trivial, but for me, they are the biggest, because they let me learn to be independent and let me grow.

Saying goodbye to the old year, we entered a new year. There seems to be a new runway before my eyes. Maybe I will fall down on this runway, but I will still stand up stubbornly and challenge many difficulties stubbornly. I firmly believe that there will always be a beautiful rainbow after the storm.

Land is the "stage" of human life and production activities. Land resources are the most basic natural resources for human survival. Without land, people can't carry out economic activities such as industry, agriculture and transportation. Agriculture is the basic industry of the national economy.

Throughout the ages, Mother Earth has raised countless generations of children and grandchildren with sweet milk. It turned out that she was beautifully decorated by junior students. However, now human beings have tortured her to death for their own interests. There is only one earth for mankind; The earth is facing a serious environmental crisis. "Save the Earth" has become the strongest voice of people all over the world.

I feel heartache for the deterioration of the surrounding environment. I think: if teenagers, as future successors, don't understand the composition of human environment and the seriousness of environmental problems, ignore the laws and regulations on environmental protection, don't enhance their awareness of environmental protection, and don't consciously fulfill their obligations to protect the environment, our lives will be destroyed in their own hands, and God will severely punish us. To this end, I am determined to start from myself, protect the environment, protect our homeland and be a guardian of the environment. In the past year, I actively participated in the tree planting activities carried out by the school, led the class cadres of our 602 Squadron to set up a "Green Angel" tree planting and green protection group, encouraged the team members to adopt a small sapling on campus, and used their spare time to decorate it carefully, laying the foundation for it to grow into a towering tree. In the signature activity of "Let the Earth Be Full of Life" organized by the school, I solemnly signed my name on it, writing down my determination and expectation for environmental protection and my vision for a better future. I actively participated in the prize-winning essay-writing activities held by the school in World Environment Day, carefully consulted and collected various materials, conducted social surveys, and wrote articles on environmental governance. I often take part in environmental protection lectures organized by the school, watch environmental protection videos, actively participate in environmental protection knowledge quiz activities, and fill in each question carefully. I participated in the website construction of "Red Scarf Green Team", and posted a lot of environmental protection pictures and knowledge on it, as well as legal knowledge of environmental protection, the development trend of environmental protection in China and the environmental protection situation in various countries around the world; Every month, I use the internet and newspapers to inquire about the latest "environmental information" of different themes and sections to tell you; We also make some publicity boards regularly to publicize environmental protection knowledge and common sense of life. Raise everyone's awareness of environmental protection; Call on students to take care of their homes from different aspects, start from the little things around them and make contributions to the surrounding environment! I actively mobilize people around me to protect and build the same and only home of mankind according to law, promote the sustainable development of economy and society, and make contributions to human civilization. Together with my classmates, I also launched the initiative of "raising a potted flower, adopting a tree, cherishing every green space and making our surroundings full of green" and "replacing foam lunch boxes and disposable chopsticks with small plastic bags to keep us away from white pollution". Let's put down the convenient bag and pick up the vegetable basket. Let's move towards a bright green tomorrow and a brilliant future!

According to a report I collected, "environmental problems are caused by unreasonable development and utilization of natural resources by human beings." Shocking environmental problems mainly include air pollution, water pollution, noise pollution, food pollution and improper development and utilization of natural resources. "Iron facts tell us that they are ruthlessly devouring human life like demons. It threatens the ecological balance, harms human health, restricts the sustainable development of economy and society, and puts human beings in a dilemma. To this end, I issued a declaration: "As long as we humans always have the awareness of protecting the environment and managing the environment according to law, the global village will become a beautiful paradise". The sky in the future must be blue, the water must be clear, the trees are shaded and the flowers are everywhere, so that human beings can enjoy the happiness endowed by nature. " The real test of our contribution to the environment is not words, but actions. "Although what I am doing now is just a small matter, I firmly believe that if we all have the responsibility to protect the environment, starting from ourselves and starting from small things, and working together to protect our homeland, we will naturally give humanity the rewards it deserves. Take a nap in the warm cradle-grassland; Grow up under the kind smiling face-the sky, and bathe in the river, the source of love.

The composition of our hut is 300 words. Today's composition is "Reach Out Our Hands", and I think of my "Reaching Out Hands" today.

This afternoon, Li Yuting returned to her hometown because of her mother-in-law, and her mother went to work. So come to our house first and wait for mom to come home from work.

After returning home, we had a rest and then began to do our homework. When I finished "Knowledge and Ability Training" in Chinese, my mother found that Li Yuting made a mistake in the third question "Look at pictures (adding and subtracting radicals)", but there was nothing wrong with the homework, so my mother asked me to teach Li Yuting.

I soon taught her and corrected my mistake. I feel very happy, and I also learned a truth: "When others need help, we should help them immediately, which not only facilitates others, but also makes us happy." This is not killing two birds with one stone. What else could it be?

Our first exhibition of science and technology consists of 300 words. I am a child who respects my elders.

Once, because grandma was talking to grandpa, grandpa accidentally choked. Hearing grandpa's cough, I immediately poured him a cup of warm water. Grandpa said I really have a good eye and the price is good.

Another time, grandpa was taking medicine, but forgot to pour water. After I saw it, I went to pour water for grandpa, but there was no water. I thought: Let's make some more water. On second thought, no, it's too long. After thinking about it, I finally remembered that there was still some water in my thermos bottle, so I poured it into a cup for grandpa to drink, and grandpa took the medicine. Grandpa said I was a good boy.

Exercise 6 Our honest composition is 300 to 400 words. Today, I can do 35 sit-ups every minute. People praised me: "look at that child, how hard he works!" Can do 35 sit-ups. " After listening to people's praise, I have to tell the truth. No one is born hard. If you know that I am still a child who can't do sit-ups in grade three, you must be confused. But why can I do so many sit-ups now?

On a sunny morning, our classmates in Class Two, Grade Three had a sit-up exam. The first batch of students who took the exam were really fierce. They all had quick brains and got good grades one after another. I, a little girl who can't afford to do sit-ups on weekdays, thought, "Isn't it just doing sit-ups?" If I study hard, I may pass. It's my turn I'm a little nervous. As soon as the whistle sounded, the exam began. As soon as I worked hard, I immediately made two. I thought to myself, I'm sure I can pass. However, something unexpected happened in the sky, but I couldn't sit up when I was in high spirits. I closed my eyes and kept my feet on the ground. I fell down just after I started. Over and over again, my final score was two. This is undoubtedly a huge blow to me. I really want to find a crack in the ground.

When I got home, I cried my eyes out. Dad advised me: "Don't cry. If you practice now, you will definitely do sit-ups. " After finishing my homework, I lay in bed and began to practice. One, two, three, I'm still practicing. Five, six, although I'm exhausted, I can't just give up. Strength seems to be competing with me, but the seventh one won't let me start. I stepped on my foot and looked up. Finally, I made the seventh one. I fell asleep contentedly.

The next day, I practiced in bed again. This time I set myself a goal: I must be 13. The first few went well, but by 1 1, my stomach began to hurt and my hands were sore. No, I want to achieve 13, Yin Qishuo, you can't give up, persistence is victory. Yes, persistence is victory. I go all out to achieve my goal. I fell asleep peacefully again.

Time flies, I changed from the little girl in grade three to an expert in sit-ups. At this time, the school held a sports meeting, and I signed up for the "sit-up pass".

The weather was particularly sunny on the day of the competition, and we all had such a strong feeling in our hearts that Class Two, Grade Four, would win. I have made full preparations before other classes enter the arena. The game started, and I played an important role as the first girl's team member. A loud noise proved everything, that is: Class 4 (2) came first.

Dear friends, do you know? I am not born hard, but I have achieved good results through hard practice. No pains, no gains. No matter what you do, you must work hard to get rich returns!

There are five people in my family, 300 words. I have a warm and happy family. My family members are my mother-in-law, my mother, my father and me.

Mom is the most important member in the family. Her hair is unkempt and a little curly. She is also a responsible person. She always finishes what she should do in the first time and never delays. She writes a lot of speeches every day for four or five hours. It's really hard! Once, I only got more than 80 points in the exam, which was very sad. Tears are not obedient's slowly flowing down. At this time, my kind mother came to comfort me and said, "Baby, it doesn't matter, as long as you try your best." It doesn't matter if it's not good this time, just work hard next time. "Listen to my mother, I smile through tears. As long as I am unhappy, she makes me happy. She is really a good mother, I love her!

My mother-in-law is also an excellent member of our family. She has a strange appearance. She has a red face. Her hair looks like half a chestnut. It's like coming out of a fairy tale book. The color of her hair is black and white, like a black and white painting. Her face is round and big, like a big head doll. The mother-in-law is so cute!

My father is a traveler in our family. Naturally, he has been to many places. He is also very kind. Even if I didn't do well in the exam, he was as happy as seeing me get a hundred points in the exam, and he was not angry at all. I love my father the most!

I am the pistachio of our family. Because when others are unhappy, I can always stay at home and Doby them.

Protecting the earth is our responsibility. If we cut down trees with 300 words, if we don't waste water indiscriminately, if we don't use energy indiscriminately, if ... when these things can be realized! However, this cannot be done by one person, and it requires the joint efforts of people all over the world!

Let's protect the earth together! Don't let her get hurt again! Let's live happily!

Chapter II: Protecting the Earth

The earth makes us the "mother" of the whole world. We should protect and care for her!

Now, with the passage of time and the rapid growth of population, all kinds of bad phenomena are very common. For example: deforestation, chemical abuse ... In order to protect the earth, we should pay more attention to the things around us and do something beneficial to the environment.

With the rapid growth of population, the arable land on the earth's surface is getting less and less, and there is a serious shortage of fresh water. The population is growing rapidly now. If this situation continues, the earth will be overwhelmed and exhausted one day! The rapid growth of population leads to a sharp rise in global temperature, so we should control the population growth and carry out family planning.

However, due to the massive deforestation of human beings, there is little vegetation in some places, which is prone to some major disasters such as floods, sandstorms, mudslides and landslides, so human casualties will definitely be serious. Therefore, we should plant more trees to reduce some avoidable hazards, such as mudslides and landslides. The reduction of trees will increase carbon dioxide and reduce oxygen, so that we can't breathe fresh air. In addition, we should also vigorously publicize the knowledge about protecting the earth and make people pay more attention to this aspect.

However, the abuse of chemical products not only pollutes the air, but also brings inconvenience to people's daily life. If the river is polluted, many fish will lose their precious lives; If the crops in the farmland are polluted, it will greatly reduce the output of that year; If pesticides are used in large quantities, the earth, which is seriously short of fresh water, will be even more overwhelmed.

It is everyone's responsibility to protect the earth. We should vigorously publicize, reduce the disasters that should not happen, and let our "Mother Earth" live forever!

Chapter 3: Protect the environment = Protect the earth = Protect yourself.

Human beings are the product of natural environment, which has nurtured human beings. Like fish and water, human beings are closely related to the environment. But what about the natural environment on a global scale? Due to the population explosion and man-made destruction, a series of problems such as abnormal climate, land desertification and species extinction have emerged. At the same time, in order to survive, we human beings have developed a lot of industrial production, which has caused serious environmental pollution and further affected the quality of the population and human beings.

So how to protect the environment from me? First of all, we should raise awareness of environmental protection, abide by social merits and have good moral character, which is also a kind of morality. When different social systems coexist, all mankind should have a code of conduct. Today, with the deterioration of the global environment, it is everyone's responsibility to care for the global environment. Everyone should have this advantage, but some people will not destroy the environment for their own personal gain. It is a part of building and preserving the two socialist civilizations and protecting the environment. Even the content of material civilization and spiritual civilization, without a certain material foundation, protecting the environment is empty talk. However, if people are uncivilized, even if they invest more, even the best equipment can't protect the environment. Every citizen has this understanding, and with this virtue, he will consciously care for trees, grasslands and forests.

Our class adds about 300 words to the subtitle composition. On a sunny Sunday, I did an interesting experiment at home, named: Let the eggs dance. Because I heard from my classmates, I was curious and decided to practice it myself.

On Sunday, nothing happened. I remembered this experiment, so I prepared a bag of salt, a basin of water and an egg first. First, I scooped up a spoonful of salt and stirred it with chopsticks. White salt particles quickly dissolve in water. I put the egg in carefully, but it didn't move. I thought: there must be too little salt. So, I scooped up another spoonful of salt, and after stirring it evenly, the eggs would not float. That won't do either! Then what should we do! I'm a little impatient and want to give up. So I poured the remaining half a packet of salt in, and a miracle appeared. I saw the eggs wriggle to the surface like dancing. "The eggs are floating!" The eggs are floating! I made it! "I can't help shouting, this is really" you can't find a place to get it, you can get it as easy as blowing off dust "!
