A 400-word composition describing computers.

There is an exquisite computer in my small room, which my parents bought for me to study in the summer vacation. My computer is silvery white, and the mainframe is flat and durable. The monitor has bright colors and clear images, and I also equipped it with two small "ears"-stereo. Even my brother, who always thought his computer was the best, envied me more and more. I can't put this computer down. Whenever I open the "window", I can't wait to explore the infinite knowledge and mystery inside, and I feel that I am swimming in the ocean of knowledge, which makes me beautiful. I remember once, at noon, I went online again. At that time, my mother asked me to have dinner. I was too interested in computers to hear it. Then my mother called again ... Finally, my mother got angry and came up to me and shouted, "Li Zhe, hurry up and eat. Do you want to try my hula hoop? " I have to turn off my cell phone when I hear this. But I still thought of an online composition and slowly walked into the canteen. At this time, I only heard the laughter of "Ha ha ……", and I just recovered. So I went to the bedroom. My face suddenly turned red. Laugh when you think about it now. It seems no exaggeration to say that computers are an ocean of knowledge and an invisible teacher. My family's computer Recently, my brother's family bought a new computer. How envious! My father told me that as long as I study hard, he will buy me one with the salary saved. I am very happy to hear the news! So I made up my mind to study hard. Finally, on a weekend, my parents took me to the "Dream Island" Cyberport in Wuxi, saying that they wanted to fulfill his promise to buy me a computer. I don't want to mention how happy I am, because this is my long-awaited ideal, and now it is finally coming true. How can I not get excited? Soon we came to the largest computer city in Wuxi, which is really a "computer city". There are various brands of computers, domestic and imported, as well as various assembly accessories. We are all dazzled and don't know what brand to choose. Finally, my father felt that Lenovo made in China was cheap and good, and it was quite affordable. After choosing it, we will take it with us at home. As soon as I got home, I couldn't wait to urge my father to install the computer quickly and see what it was like. Father was so anxious that he couldn't even eat, and he was busy eating according to the instructions. I was his coolie, too, and took all the parts apart, but my father assembled them soon. I hurried to the computer to see what it looked like, a long LCD screen with a pair of stereos on each side. This is my home computer, and I suddenly feel so proud! After the computer was installed, my father began to turn on the power to install the program and debug it. I am always eager to ask my father, "Are you ready?" My father said "soon". Indeed, in a short time, my father downloaded some programs and installed some small games to learn puzzles, saying let me try. I am very happy to sit in front of the computer and have a good time, but my father told me that I bought the computer mainly for our study. We can use it to learn a lot of new knowledge online, and we can use it as a tool to improve our study. Of course, this requires us to learn computer knowledge well, know how to use it, and it is also possible to relax and entertain occasionally. I remembered my father's words and secretly made up my mind to study computer knowledge hard in the future and let it serve us better! Follow-up: describe the appearance of the computer!

I remember once, the teacher gave us an assignment to find information about rare animals.

I turned on the computer and connected to the Internet. I open Tencent "TT", click "Baidu" and search for "rare animals".

The computer immediately showed many websites about rare animals, and I chose the website "World Rare Animals".

In this website, rare animals are divided into four categories, the first category is rare species of birds, the second category is rare species of reptiles, the third category is rare species of amphibians, and the fourth category is rare species of fish.

I chose the reptile, which first showed the gecko.

I wonder: Gecko is not a rare animal, is it? I opened the webpage and got a fright.

It turns out that this gecko is the largest of all gecko species.

Now the number is less than 20 thousand, which is on the verge of extinction.

Then I saw four-claw tortoises, turtles and so on.

None of these animals exceed 30,000.

Then I read a lot of information about animals, and their existing number shocked me.

I also know that some people kill a lot of rare animals for profiteering.

I'm sorry to see this.

I think animals are our good friends and we shouldn't hurt them.

Computer is not only a good helper in my study, but also a good friend who brings me joy.

Once, my parents were on a business trip and I was alone at home.

After finishing my homework, I turned on my computer and clicked on my music library. Beautiful melodies flowed into my ears. I feel very good.

I opened the "Little Games" folder again and chose the little game "Dog's Gift".

I played a little dog and looked around for my present.

I opened the hole in the tree first, and a squirrel ran out and said, "Why do you disturb my sleep?" Then he took out a pine cone and hit me. I quickly apologized and ran back to my dog house to hide.

After a while, I left the kennel and continued to look for presents.

In order to find a gift, I was drenched by the fountain in the flower bed and laughed at by the mouse by the pool ... but I finally found my gift-a bone in the vegetable field.

Look, with a computer as a friend, a person will not be lonely at home! My grandparents are far away in Shijiazhuang. My mother and I often greet them and chat with them through the computer network.

At first, we communicated by typing. Later, with headphones, we could have a voice chat.

It's more convenient now. After my mother installed a camera, it was like installing a videophone. My grandparents saw me through the video, and they were happy from ear to ear! The computer accompanies me every day, and I feel that my vision is broader and the world is more exciting! I am happy to make friends with computers.

For example, a computer is faster than a calculator, and that is a computer.

Computers can not only calculate mathematics, but also have many other functions.

The computer consists of two parts, one is the main chassis, and the other is the display screen.

If a part is missing, the computer will not work normally.

Among them, the main chassis is the most important, because all files stored in the main chassis are the most important files of the owner.

If the main chassis is taken away, the most important files in the machine will be lost.

The appearance of a computer is basically square. Now the latest night crystal computer is very thin and light. There is also a portable computer, which is relatively small and has no main chassis, but it is more difficult to operate than others. This computer is called "notebook computer", and its colors are white, black and gray, which is the most common.

Computers have many uses and functions.

A computer can store many files, keep a diary, look up information, print information, surf the Internet, chat and so on.

A computer with so many functions must be expensive. Computers with so many "treasures" are naturally so expensive.

Computers have so many functions, but also many shortcomings.

Many college students, primary school students and even adults are attracted by computers and obsessed with the internet, and as a result, they fall into a deep trough and cannot extricate themselves.

So I would like to remind you that computers have both advantages and disadvantages. When using a computer, you must be moderate.

The society is developing, the country is progressing, and the motherland expects us to create better things.

There is an exquisite computer in my small room, which my parents bought for my study in the summer vacation.

My computer is silvery white, and the mainframe is flat and durable.

The monitor has bright colors and clear images, and I also equipped it with two small "ears"-stereo.

Even my brother, who always thought his computer was the best, envied me more and more.

I can't put this computer down.

Whenever I open the "window", I can't wait to explore the infinite knowledge and mystery inside, and I feel that I am swimming in the ocean of knowledge, which makes me beautiful.

I remember once, at noon, I went online again. At that time, my mother asked me to have dinner. I was too interested in computers to hear it. Then my mother called again ... Finally, my mother got angry and came up to me and shouted, "Li Zhe, hurry up and eat. Do you want to try my hula hoop? " I have to turn off my cell phone when I hear this.

But I still thought of an online composition and slowly walked into the canteen.

At this time, I only heard the laughter of "Ha ha ……", and I just recovered. So I went to the bedroom.

My face suddenly turned red.

Laugh when you think about it now.

It seems no exaggeration to say that computers are an ocean of knowledge and an invisible teacher.

My computer composition is 400 words. How about prose? Paper, right? Composition? My home computer 300-word composition My home computer consists of a host, a monitor, a mouse, a keyboard, a printer and a stereo.

The computer monitor is black. It has a crystal clear face and a fat head hidden behind it.

The host's belly is bulging, which must contain a lot of knowledge! This mouse looks like a little mouse with a long tail! We all use computers at home, but for different reasons.

Dad uses the computer to watch the news and learn about national events, such as where a fire broke out and how many people were killed or injured.

The data on the computer is very accurate.

Mother prepares lessons with the computer.

There are many teaching designs and courseware on the computer.

So my mother often uses computers.

Grandpa plays chess on the internet with the computer. Grandpa often has to fight "life and death" with others before he is willing to give way.

I use the computer to look up information. Whenever I have a question, I will ask Baidu for advice. Really like a knowledgeable elder, he always gives me a satisfactory answer.

I love you, my dear friend-computer.

I will cherish you, use you correctly, and let you bring help and convenience to my study and life.

...

Composition: The computer in my mind is about 400 words. In this 2 1 century, when high technology is developing, we must learn a lot of knowledge to keep up with the pace of society.

Now the rule of "illiteracy" is not only to learn what we want to learn, but also to learn computers well.

The computer has brought me into a new world.

Computers have played a great role.

Students often use it in their work. Of course, we also use it in our study.

My English is not good, so I often don't know how to learn English well.

We should learn computers well and know that computers can search the information we want.

I turned on the computer and typed in "How to learn English well". Soon many articles about learning English came out.

You see, it can be found in less than a minute. If you look in the library, you will find it.

Computers help me learn English well and open up a new world for my study! The computer spans the whole world, and it can flow from home to home, and it can learn the governance that is beneficial to home.

You can learn about the customs, culture and views on some things between and.

Middle school students should learn some cultural knowledge.

Every computer is connected.

For example, we can enter the international chat room and stream in English, which can exercise my ability.

I had a cultural exchange with a beautiful girl and let me know that their family is very developed.

Their lives are very rich.

I also know the local customs there, and the computer has made me know many friends! Computers are very advanced, which makes us feel novel.

In the medical field, computers have played a great role.

In medicine, doctors use computers to help them treat diseases.

Some need very delicate surgery, but now they don't need surgery, just a computer can cure the disease.

Many scientists have done many important experiments with computers.

Just like "SARS", it is scientists who use computers to analyze and learn the origin of SARS and extract the essence, which makes many people survive.

Many scientists use computers, and many accurate figures can only be obtained by using computers.

In some developed cities, teachers don't have to give lectures in school classes because they all use computers.

This is also very representative! It brought me into another new world! However, playing computer games takes time. If we play computer games too much, the time we spend studying will be greatly reduced, unless we are geniuses who can learn without watching. As far as we ordinary people are concerned, it is strange that our academic performance will not decline! Secondly, playing computer games, especially for a long time, is very harmful to our eyesight and health. When you indulge in the pleasure brought by computer games, your eyesight will decline day by day unconsciously. When you finally wake up, it's too late! Maybe I can find the healthy body I once had.

Third, playing computer games is especially a waste of money. As primary school students, our pocket money mainly depends on parents' gifts. Imagine, whose parents are willing to give us money to play games online very readily? Therefore, in order to play computer games online in Internet cafes, we are bound to ask our parents for it under various excuses, otherwise we will try our best to make money, and there is no mind to study at all, and some students even go to the point of no return. Why bother? There are many dangers of computer games, so I won't list them one by one.

Some people may not be convinced. You have said so much about the dangers of computer games. Is the computer game not good? At least playing computer games can exercise our body, improve our reaction ability and the rapid coordination ability of our hands and brains, help us understand computers, know computers and learn computers, and let us relax in the intense study. There are still many benefits! Besides, aren't there many adults who are addicted to computer games? Therefore, only by creating a green network world can we enjoy the computer world more harmoniously.

Write a composition about computer supermarket, about 400 words. In 2030, with the rapid development of science and technology, supermarkets are also changing with each passing day: automatic cash registers, vending machines, automatic commodity detectors, automatic cleaning machines, automatic cargo conveyors ... these machines gradually replaced the staff, facilitated our lives, and bought goods home at a fast speed.

There are too many goods in the supermarket.

At this time, the "automatic search machine" has played a role.

It will input the location of any commodity into the computer and never forget it.

When you look for the goods again, you don't have to work hard, because you may be sweating all over, but you still can't find them. At this time, as long as you enter the product name in this "automatic search machine", it will immediately tell you where the product is.

There is a vending machine in the freezer.

When selecting goods, press the label and put the corresponding money into the "coin slot". After hearing the beep, open the temple marked "delivery slot" under the machine, and the goods will be inside.

If someone forcibly takes out the goods, the sensor will light up and notify the security guard.

At the same time, it will accurately throw an "electronic tracker" at the thief, and the security guard only needs to follow the instructions on the palm to find the thief.

The automatic cash register works with the conveyor belt.

After the previous customer has left, you just need to put the items you want to buy on the conveyor belt. The automatic teller will tell you how much money it is and let you put it in the designated place.

If someone is found to have escaped with the goods without paying the money, it will notify the security guard, and at the same time, it will stretch out its big hands on both sides of the hide to catch the thief and wait for the security guard to deal with it.

At the end of the day, there is a lot of rubbish.

But the cleaner can sit in the office with peace of mind.

What replaced them? Haha, that's the magical "automatic cleaning machine".

It has a pair of big eyes and a pair of hands, and the garbage everywhere is put into the trash can by its big hand, so the trash can is bulging every day.

We all know what's in the lamp. Now let me talk about the "automatic cargo plane" in the dark.

It replaced porters.

It will put things in its "belly" and move to the place to be moved through the underground passage.

As long as there is a power failure, the "automatic freight forwarder" will take the self-demand method: first turn on the alarm to inform people.

Second, use your own electricity and continue to work.

Do you think it's practical, son?

Imagine writing an encyclopedia of 400 words. "The more I grow up, the more lonely I am, and the more I grow up, the more uneasy I am.

I had to watch the wings of my dream break, and suddenly realized that the road ahead was not smooth. Is this change inevitable? ..... "Will you miss it? The hazy heartbeat when I was a child: the red tick on the exercise book and the joy of 100 on the report card; The fear of being scolded for doing something wrong … and everyone dreams of becoming an adult as soon as possible.

However, after a long time, I suddenly found that "you are too young to understand" in the large population has become "you are too old to understand" ... These two sentences contain completely different emotions! One is cordial, and the other is angry.

Once, I wanted to have a class reunion.

I'm already in junior high school, and I want to see my primary school classmates again.

So, I looked through the phone book in the room and contacted one by one.

I fought and fought, and I cried.

It turns out that their phone numbers have been changed.

Is this growing up? ! Growing up is a childhood dream; Now, it has become a reason to bear everything.

When you grow up, you will only be lonely! When I grow up, I am very lonely. Is that so? When I just bought it back, I just read the title. I really thought it was the kind of "loneliness equals growing up."

I think this is my autobiography, and Sister Braid will tell her that "the more I grow up, the more lonely I am".

In fact, this book is about a boy named Li Ke. Unlike his peers, he doesn't allow anyone to get close to him. He is still a "traveler".

But the more he is like this, the more people around him are worried: first, there is the "Obasan Girl Trio" composed of Rain Stopping, Thousand Flowers and Pan Am, and then the middle school deskmate, the persistent pursuit of the girl, and the heartache and yearning of the two mothers.

Of course, there is his best friend Li, who can hide everywhere, because he is suffering from blood and is destined to become an island.

At the end of the story, he found a huge secret-the reason why his father left him and his mother: he and his father got the disease that only 2.5% people in the world got, and it was the most serious kind.

This is called facial amnesia.

It is the faces you used to know that disappear in front of you one by one, and the world gradually becomes like an island.

Finally, it is so serious that you will disappear into the mirror.

He was still deeply crushed, and all those who loved him felt that his side, with everyone's weak strength, gathered into a powerful quantity.

Many things have happened, and finally it entered Ke Li's heart and purified his mind.

Finally let him stand up again.

This is the story of a boy's sad wandering secret and a group of girls' stubborn pursuit of truth.

If this is all that travelers have experienced and grown up, I believe that one day such a hard pursuit will not only touch the soul, but also touch the soul.

If he and his stubbornness are condensed into harm, will he continue to be "strong"? If you read the book Lonely Growth carefully, every word will shake your heart.

If you carefully taste this book, it will make people smell the pure fragrance, the fragrance of love and affection, as if it were the coolness of mint and the sweetness of grapefruit ... This shiny book hides dreams and happiness; Hidden kindness and courage; Hidden romance and persistence; Hidden happiness and simplicity.

He is like a pair of invisible wings, giving us strength and letting us fly over despair with hope until all our dreams blossom and bear fruit ... The more we grow up, the more lonely we become. Yes, the more I grow up, the more lonely I get.

When we grow up, we are inevitable, but can't loneliness be eliminated? If everyone still has a pure childlike innocence in their hearts; Everyone is very atmospheric and doesn't haggle with others; No one will be "wily"; Everyone is not hypocritical and does not pretend to be himself ... So, will there be "more and more loneliness"? Definitely not.

Remember: when you grow up and are lonely, don't complain. After all, this is a hurdle in life for everyone. As long as you make up your mind and face it bravely, you will certainly be able to cross this hurdle.

"After many years, you came back to me, feeling insecure and filled with your tired eyes.

Look at me and tell me if you still believe in fairy tales.

You once told me that every heart is lonely, every heart is fragile and eager to be touched.

When your heart is burning bravely, it will never shrink back.

The more you grow up, the more lonely you are, and the more you grow up, the more uneasy you are.

I have to watch the wings of my dream break. I have to take back my words and ask myself, where are your innocent eyes? The more you grow up, the more lonely you are, and the more you grow up, the more uneasy you are.

I want to open your parachute behind me, and suddenly I understand that the road ahead is not smooth. Is this change inevitable? You once told me that every heart is lonely, every heart is fragile and eager to be touched.

Look at me and tell me that your heart is still burning ... "

Excellent history and new knowledge of 400-word plum blossom I praise the faithful pine and cypress, I praise the delicate peony, but I admire the blooming plum blossom.

One year, about the season when plum blossoms are in full bloom, our family went to visit the plum blossom exhibition together.

As soon as we entered the gate, we were attracted by the thick plum blossom aroma and amazed by the refreshing aroma.

Then, we began to look at plum blossoms.

The pink petals are covered with snow, reflecting the breath of winter.

Feel it, soft as snow-white cotton, comfortable, really comfortable! Smell it again, and you will think of a garden full of flowers, as if you were there.

"There are some plums in the corner, and cold ling is alone."

This well-known poem, in this flower show, I finally understood its metaphorical significance.

Plum blossom, in people's minds, is a symbol of being strong and proud of snow.

The color of plum blossoms is gorgeous but not demon; Plum blossom fragrance, quiet and elegant; Meihua's posture is ancient and exquisite.

I picked a plum blossom, smelled it carefully, smelled it ... until the sun set, the song of the red dove called back our hearts. We woke up from a dream, came home, put plum blossoms in my vase, and suddenly the room was full of flowers.

In my opinion, we should not only transplant the fragrance of plum blossom to our home, but also transplant its spirit to our hearts.

Plum blossom, is it not a worker who silently contributes to us? No matter whether it is cold or hot, whether it is windy or rainy, whether it is ice or snow, they are silently sticking to their posts. In this plum blossom exhibition, I not only saw the beautiful appearance of plum blossom, but also saw its unyielding inner world.

Shakespeare said: "Books are the nourishment of the whole world.

"I think this metaphor is very considerate because I have an indissoluble bond with books since I was a child.

When I was two years old, my mother bought me some picture books to show me. In my opinion, those little books full of pictures are more precious than gold.

Later, my mother bought a radio and some tapes and played stories for me every night. I listen to stories and fall asleep quietly every night.

When I was six years old, my father bought me many comic books, including The Journey to the West, Seven Colors Flower and The Story of Rainbow Cat Lan Tu.

Later, my father bought me many story books, such as Grimm's fairy tales, Andersen's fairy tales and so on.

When I was in primary school, none of these stories satisfied me. Suddenly one day, my father put some famous books in front of me and said, "I will take charge of the middle school library this year, and there will be more books in the future."

"Hearing this, I jumped three feet high and went to my father's library as soon as I was free.

I read it quickly and swallowed it, smelling as if I didn't ask for an answer.

Now I'm in grade five, and I've read The Romance of the Three Kingdoms, The Water Margin, A Dream of Red Mansions, The Journey to the West, My Childhood, Education of Love, Old Things in the South of the City and so on.

I have learned a lot from books that I can't learn from texts, and I also know how to write a composition, and I have also learned some famous sayings from ancient and modern times, so I will read more books and be an omnipotent person in the near future.

Please indicate the source? A 400-word composition describing computers.
