When it comes to eating, everyone will definitely have a lot of experience. Everyone has his own preferences, but how can we form the habit of eating scientifically?
Children must love cold drinks! Eating too many cold drinks can lead to headache and abdominal pain. I remember one time: it was summer and it was very hot. When I came home from school, I had a cold drink. Wow! It's so cold that it won't burn after eating it. When grandma wasn't looking, I secretly drank two more cups, which made me feel so comfortable. But at night, I suddenly had a stomachache. Father looked at it and said, "I must have drunk too many cold drinks!" " "Go to the hospital to hang up the salt water, and the stomach won't hurt. I thought to myself, I will never drink cold drinks again. Dad says boiled water is the best drink.
Eating too much chocolate can also cause abdominal pain. I remember another time: grandma bought some chocolate, because I like chocolate very much, so I was very happy. I can't wait to say to my grandmother, "Grandma, can you give me some chocolate?" Grandma said, "Don't eat too much." I took out my chocolate. As soon as I smelled chocolate, I couldn't control my mouth and ate a lot of chocolate at once. After a while, I felt a terrible stomachache, so I couldn't help having diarrhea. Grandma said, "you greedy bastard, I told you not to eat too much." It's strange to eat too much without diarrhea! " "I dare not eat more chocolate in the future.
In addition to eating less drinks and chocolates, basically all foods should not be eaten desperately because they love to eat. Son, gluttony is a bad eating habit, so we must correct it quickly.

Science is very common in our daily life, and we can't live without it. There are many dietetic sciences, because they are in our life, and we can't understand them without careful observation and thinking. Now, let's walk into the mystery of "science in diet".
There are fierce struggles now, such as exams, competitions and a lot of activities. Everyone should be full, with diverse patterns and a combination of thickness. The food is delicious and full.
Eat some fruits and vegetables, green leafy vegetables containing vitamins and minerals, such as rape, celery, bell pepper, beans, cauliflower, etc. Fruits should be fresh dates, apples, persimmons, papaya, hawthorn, oranges, sweet oranges, kiwis, grapes and so on.
You should also eat some nuts and bacteria, such as peanuts, melon seeds, walnuts, mushrooms, fungus, seaweed, kelp and so on.
Vitamin B 1 is especially helpful to the brain, and cereal oatmeal can play a very good role. Eat less sweets such as sweets, drink less coffee, eat less fat and high-fat foods, and it is best not to eat fried foods.
Don't eat too much, don't study immediately after meals, and exercise properly.
Food science is close at hand.

What is happiness? Some people say that happiness means having a good meal when you are hungry; Some people say that happiness is to finish endless homework and lie on the sofa at home and watch a movie quietly; Others say that happiness is taking, happiness is wealth, happiness is glory ... In fact, happiness is not reflected in earth-shattering, it is on the "puppy's tail". As long as you look forward, happiness will follow.
"Ah-"I yawned and looked up at the clock. It's already night 10.
Sitting in front of the desk, looking at the high homework pile, I dare not slack off, and the pen tip continues to fly.
But the pen only jumped for a while, and then it began to get astringent, and it was no longer so smooth. It seems to want to have a rest, too Although my eyelids fought, I had to work hard, because today's work can only be completed today! "Boom-"I don't know when my lovely little flower cup appeared on the desk.
Gee, isn't that espresso? "Son, I'm sorry! There is no sugar at home, so dad can only let you drink this cup of bitter coffee to cheer you up.
"Suddenly, my eyes were full of tears. I savored it carefully and slowly. Although it tastes bitter, it condenses dad's sweet love.
It turns out that happiness is a warm cup of coffee.
On this day, clear skies in Wan Li, Wan Li. I went for a walk in the nearby park alone.
I felt a little tired after walking around, so I sat in a chair on the side of the road and enjoyed the surrounding scenery while drinking some juice.
Inadvertently, I saw a small and exquisite bird's nest on the tall plane tree.
I took out my telescope and put on yellow glasses to observe it carefully.
There are two chickens lying in the nest. I saw my mother biting insects and feeding the birds bit by bit. At the first sign of trouble, the mother bird will spread her warm wings and cover the whole nest; After eating a delicious meal, the mother bird gently stroked the bird's body with her feathers from time to time, much like a warm little family! It turns out that happiness is lying in the arms of parents and enjoying the care of family members.
Every day when I come home from school, I have to cross a long road. Every time I see a familiar figure-a 9-year-old disabled boy, who can only spend time in a wheelchair because of an unfortunate car accident.
At this time, I will push his wheelchair and help him cross the road smoothly.
Listening to his sweet and cheerful voice, "thank you, brother!" " I feel extremely happy.
It turns out that happiness is the happiness you get after helping others.
Happiness is like this. As long as you feel it with your heart, you can reap unlimited benefits.
If you are satisfied, please accept it.
The composition about the introduction of the article is about 400 words.
My desk My desk is full of messy things: in the upper left corner of the desk, there is a pile of books in the shape of a gyro (first of all, it is "natural" and has not been processed).
At the bottom of the gyro is a thick and narrow English dictionary, which is particularly difficult to look up. The words are small and yellow, which belong to the standard museum display.
There are several textbooks from junior high school to senior high school in the middle of the gyro, which are old and new enough to witness the author's yesterday and the day before yesterday.
At the top of the gyro, there is a jumbled notebook and a CD. Geographically, this is a relatively active plate in the near future, sometimes overlapping and sometimes dislocating. Fortunately, the plate has self-knowledge and knows not to collide with the desk. Therefore, even at the most critical moment, he can always maintain a swaying posture, which is quite statesmanlike.
Near the gyro, there are two boxes of "time bombs" that come out of nowhere-a box of Tongtaixing compound Huonaosu and a box of Jiahe Baifuning. They always warn my body not to force them to explode prematurely.
On the right side of the "bomb" is a desk lamp, a yellow lampshade, a black neck, a yellow lamp holder, a black knob, and the standard color of the leader's hearse, which shines on me every night and reminds me of those great men who died in the West forever. A little further to the right, there is a decoration that I don't know its name.
It has a crystal globe, a clock, a pencil case and a business card case. When I first brought it back, the whole decoration gave off a dazzling metallic luster, resplendent and dazzling, but after a while, except for the globe with a hint of crystal luster, the rest of the gold faded.
Whenever I see it, it always reminds me of the end of those corrupt elements who went from light to darkness, which is very Japanese.
On the right side of the display screen is a pen container, which contains a batch of pens, pencils and ballpoint pens that cannot be written in any color. They are used to throwing things around when they are free. I never worry about whether the pen will fade and leak ink when I fall, so it is very comfortable and comfortable to use.
On the far right side of the desk (which can be represented by coordinate axes), there are a bunch of books that can be read by gyro.
Only the shape is "mountain" instead of top.
There are three CDs on the top of the mountain, which is obviously much more advantageous than the gyro.
After introducing the main items of the desk, there are some minor items, such as transparent adhesive, waste paper, watches, cups, refills, correction fluid, portraits, etc., which also play a role in filling the desk and make a great contribution to its disorder.
Even better, messy is also a kind of beauty. May the beauty of the desk last forever.
Scientific composition (400 words)
So far, one of the most successful animals on earth is dinosaurs.
Dinosaurs ruled the earth for 6,543.8+billion years, and there were many kinds in water, air and land.
Dinosaurs flourished in the Mesozoic era (the Mesozoic era, that is, a geological age from 65438+8 1 10,000 years ago to 63 million years ago), but they became extinct at the end of the Mesozoic era and disappeared from the earth's surface.
Almost at the same time, half of the known animal and plant species on the earth became extinct.
Such a large number of biological extinctions occurred in a very short time, which naturally led to various conjectures and assumptions.
Some people think that the extinction of dinosaurs may be due to their overdevelopment, disproportionate body size and nervous system, which made them slow to respond and difficult to find food. At the same time, they also faced smaller and more flexible mammals at that time.
Some people think that some plants on which dinosaurs lived at that time evolved into flowering plants, and dinosaurs could not adapt and eventually starved to death.
The extinction period of this species happened between Cretaceous and Tertiary in Mesozoic, so it was also called C-T extinction.
Coincidentally, in this ancient time, there was a thick layer of red-brown clay in the rock stratum of the earth.
Geologists can find this kind of fine clay sandwiched between Cretaceous and Tertiary strata in many parts of the world, such as Italian, French, Tunisia, Danish and New Zealand. Judging from the thickness of this kind of clay, it is estimated that this kind of clay has been deposited for a short time, and it took 100 years to form.
The American physicist L.Alvarez and his geologist son assumed that the source of this clay was not deposited by earth materials, but some micrometeorite dust that kept falling to the earth's surface at that time.
If their hypothesis holds, the content of iridium in this red clay should be higher than that in other rocks on earth.
The analysis results show that the content of iridium in this clay is 30~ 160 times higher than that in other geological rocks.
This result supports Averys' hypothesis that this layer of sediment came from space rather than the earth.
The Chinese story composition I know is 400 words.
A cow and a horse are grazing in the same trough.
The cow proudly shows off: Hey, Marco, I found that I am a great cow.
I made a new discovery recently.
The horse quickly asked, Niu Ge, what did you find? Don't keep me in suspense, just say it! Niu said excitedly, now I know why physics is called physics.
Do you know who founded physics? This horse is also very knowledgeable. It said, well, it seems to be a guy named Newton, right? The cow said: Yes, this is the buddy.
Because of his great contribution to physics, in order to commemorate him, people used his ox character in physics. Speaking of physics, it is also a cow science.
Ma smiled: Hey, Niu Ge, I think you only know one thing and nothing else.
How to write "Woods"? It's a cow character here, but there are some other characters.
Doesn't mean anything, okay? It just means no.
In other words, physics is not a cow science.
Cow is furious: Bah, you crazy horse! Get away from me, I'm crazy about you! Hey, I am so great that I can easily understand another idiom!

Growing up, I thought that happiness meant that my mother would buy me whatever I wanted. Now I understand that happiness is to spread love to every corner.
The Chinese New Year is coming, and all the students in our class are discussing this topic noisily. Suddenly, Mr. Zheng came into the classroom with a big smile and a greeting card in his hand. Everyone was curious and just wanted to ask. Mr. Zheng came up to me and said, "Zhang Lu Yi, this is from Zhang Zheheng! Is he your brother? " I quickly replied, "no, no, he is my brother!" " "The students looked at me enviously and said noisily," Wow! My brother never sent it to me. It's very kind of your brother. Open the greeting card and see what it says. "At that moment, I felt so happy that I really wanted to sing a song! Writing here, I can't help but think of the earthquake, and then many touching things happened. Money and materials are donated all over the country, and our school is no exception. I remember that sunny morning, students and teachers came to school with money and materials, ready to give their love. I sent my favorite doll out, hoping to let the children in the disaster area have a happy Children's Day. In the evening, I had a dream that the children in the disaster area were holding their dolls happily again. I laughed out loud from my dream.
Whether you give or be given, you are happy.
The composition about happiness is 400 words "Where is happiness?" Listening to the first song of the first lesson, I also asked myself repeatedly.

For a blind child, it is really hard to be optimistic without seeing how painful this colorful world is.
But this blind child who is only ten years old is so strong and cheerful. After only three years of piano study, I entered the top three of the world series. This is Liu Hao.
Liu Hao also has a good mother. Due to family conditions, her mother brought him 200 yuan to study in Beijing. The rented house has no heating, and sometimes there is no food for days. Liu Hao Jr. can only practice in the piano shop secretly at night.
However, mother and son are very happy.
Liu Hao said that he loved his mother and music. Being able to play the piano is the greatest happiness and also the greatest happiness. What is invisible is just a little sadness. Every time I play the piano, all this disappears.
I think, if I am blind today, I am not sure that I will be as optimistic and strong as Liu Hao.
However, a blind child loves life so much, why don't I cherish the happiness now? What is happiness? Happiness is my mother's words at night: eat more beans! Don't always be picky about food.

What about our happiness? Is to snuggle up in mom's arms
Can happiness be represented by thick money, beautiful silks and satins and delicious food? I don't think so. Even if we eat pickles, drink rice porridge and sleep on straw mats, as long as we have a happy and harmonious family, aren't we afraid of all difficulties? Happiness is the offspring of China and China.
In ancient times, China was one of the four ancient civilizations.
Now, China is a powerful country with developed science and technology, rich resources and rising economy.
I am proud that I am from China! Happiness is that I am the successor of 2 1 century. There is air conditioning when it is hot in summer, heating when it is cold in winter, and internet when it is difficult.
2 1 century has given us a better living environment and learning environment. Should we study harder and harder? I have a qualified father who works hard outside every day for my college education.
I have a hardworking and kind mother who helps me study, cook and wash clothes at home every day ... this is my happiness.
When my mother brought me my favorite meal, I found it full of happiness.

Grade 5, No.2 Central Primary School, Huangcun Town, Daxing District, Beijing: Xu's composition on happiness is 400 words. Many people pin their happiness on the future: when they grow up, they will be happy if they are promoted and made a fortune.
In fact, this is a misunderstanding and misinterpretation of happiness.
We face happiness face to face every day, and happiness is in life.
Scene 1: Warm light comes home from school a little late every day. There is a long, dark and narrow road from the stairs to the door. Every time I can see a lamp lit by my mother, it seems to tell me that someone at home is waiting for me to go home.
From then on, I am no longer afraid of what to do after school, and I am no longer afraid of the dark, narrow and long road.
Because, there is a mother's lamp always on for me.
Seeing the bright light lit by my mother, my eyes were moist, and a kind of sweet happiness came into being.
Scene two, a warm smile. She is a physics teacher who has only taught us for two months. She is neither beautiful nor tall. She just warms every child with the most sincere love.
The teacher's physics class is very interesting, which fills our blank hearts with her unique voice and unique teaching methods.

400-word Terracotta Warriors and Horses
Exam "Students, take a math test tonight and review well." The math teacher told us. Then the Chinese teacher came to take over: "Attention, everyone, we will take the sixth unit of Chinese tomorrow." Then the physics teacher said, "Let me tell you something. We have an exam on Sunday." "wow! How so many exams! " The students are sighing. The chemistry teacher came in. He said, "Listen, I'll tell you ..." Before we finished, we shouted, "Take an exam tomorrow and review well." The chemistry teacher smiled ... then, we reviewed nervously. Before I finished reciting the mathematical theorem, I took out my Chinese book and reviewed it in a hurry. It suddenly occurred to me that there was still a problem in physics that I didn't understand, so I dragged it out again. I feel that chemistry is still a problem ... just after reading a few pages, the class is over. I sighed helplessly: "That's it, so we have to burn the midnight oil." So I picked up the book in a panic and ran. I ran into the dormitory, washed my feet as fast as I could, and then went to bed to read carefully. But after a while, the lights went out again, and there were no lights in the dormitory. The light went out. How time flies. "Wash your face, rinse your mouth, comb your hair and rush into the classroom to read." Doing exercises-"Outside, the teacher on duty shouted with a trumpet. Hey! I stretched myself and joined the sports team. I studied by myself early yesterday morning, so I can read a good book. "Atchoo-"I sneezed loudly. Oh, no, why do I have a cold? The exam is coming soon. What should I do? "The exam is over, sit down quickly," the teacher shouted. I fainted when I got the test paper. This paper became blurred in front of me. I ... Needless to say, my Chinese exam was a mess. Then I didn't do well in chemistry and physics. Almost every subject gave me a blow, and almost every question was very strange. What should I do? Just when I was worried, the history teacher came in with the paper in his arms. I was so scared. After handing out the papers, I did them one by one, which was very easy. I was so happy that the teacher gave me a hundred points at once. I cried happily and jumped! "Xiao Juan zheng, what are you doing? In the middle of the night, what bed "My classmate in the lower bunk said to me," Why, I hit the bed? "I woke up, so I was dreaming. Get up? Oh, my God, there is an exam today.

Mathematics: In the process of doing problems, record the wrong application problems with special white woolen cloth, and find more similar problems to do, so as to consolidate and improve the calculation ability.
After all, I am a physical chemistry student in Grade One. Let me sum it up myself. ) That's all. Anyway, I hope to adopt it. Give me something hard.
Otherwise I typed so many words for nothing.
The composition of Science Makes Life Better is about 400 to 500 words.
Science makes life better. From ancient times to the present, many peerless celebrities have set out for science: Copernicus risked his life to put forward Heliocentrism, Edison discovered tungsten wire and invented electric light through thousands of experiments; From "three people, there must be my teacher" to "scientific development depends on everyone."
"These are all around science.
In ancient times, people were always influenced by theism, did not believe in science, burned incense and worshipped Buddha every day, but in the end they achieved nothing.
Many people worship Buddha, believe in Buddha, and finally suffer the consequences.
But many people believe in science. Although many people were guillotined, they would not give in to death. This spirit is the crystallization of science.
Now, people live a happy life, have all kinds of electrical appliances, make full use of all kinds of resources and apply all kinds of knowledge, which is also the crystallization of science.
Once, I heard such a question: "Are people living well in ancient times or people living well now?" I don't know how the questioner answered. Everyone looks at the question from different angles, but I think science is happiness.
A thousand years ago, people lived a simple life and were riddled with bad karma. Their connection needed to be spread by flying pigeons. It is also a difficult journey from Shanghai to Beijing.
There is no cure for pneumonia, so the whole family can only pray. Over the years, the war has been going on, just for the land, which is pitiful and pathetic.
People nowadays are full and happy.
The medical technology developed at present can cure almost all common diseases in life, and the extended people have more time to expand and enjoy life.
The rapid development of natural science and technology such as biology and chemistry has brought rich and colorful spiritual food to people who were originally curious.
While exploring and inventing, human beings affirmed their self-worth, and while enjoying the benefits brought by science and technology, they also gained happiness.
With such great wisdom, mankind has discovered and created so many "miracles".
The double helix decryption of DNA molecules has benefited the internet of thousands of families, the space shuttle was sent into the universe at cosmic speed for the first time, and the development of cloning technology to help patients with diseases regain their lives was unprecedented in ancient times, and this is the symbol of human science.
Science can make life better because there are a group of good people who make rational use of science and technology.
They apply beautiful science and technology to the construction of social harmony, the enrichment and shaping of human material and spirit, the endless pursuit of truth and the worship of moral quality.
When someone asks you which era you think people are happier, please don't hesitate to tell him now.
Because we live in the cradle of science and enjoy the happiness brought by science and technology.
We also have reason to believe that the rapid development of science and technology will be 100% used to benefit mankind, nature and the world, so that science will bloom with the most beautiful and pure brilliance! Give you a model essay for reference. I hope you can write your composition well. I wish you a step-by-step promotion in your study!
Please indicate the source for reprinting. There are 400 words of scientific composition in the diet.
