At that time, no one in the family knew anything about computers. My mother installed my own "happy house" software step by step according to the instructions, and repeatedly told me not to touch the computer to avoid damage. I still can't help it. I got into trouble by playing computer while my mother was not looking. I can't let my mother know, because I have unloaded all the "happy homes" that my mother took a long time to put in.
I was scolded then. The computer gave me a good impression at first, but suddenly it disappeared without a trace.
I hate computers. I don't like them anywhere It is a monster. I often complain that my mother bought a junk and left it at home. From then on, I ignored the computer.
Until the fifth grade, we set up information technology courses, which made me have a soft spot for computers. You can also contribute. To be honest, I didn't take the information technology course seriously at first, and I won't take the graduation exam anyway.
I don't even read the new book, so I have no choice but to listen in class. After a class, I changed my view on this matter.
Information technology tells me that a computer is a machine for processing information, not a human brain. It also inputs information, remembers information, processes information and outputs information like the human brain, but I haven't mastered these functions yet. Just as people can't observe things with their eyes, remember what they see with their brains, think about what is written in their brains, and even write the results of thinking on paper, isn't this a sad result? With more and more knowledge of information technology, my attitude towards computers has also changed. It doesn't seem so annoying. The ugliness in the eyes of the past has turned into a smart head, and information technology can make it show its functions in front of my eyes.
I can use the information technology I have learned to design a homework schedule for the class, with exquisite patterns inserted in it; I can input all my compositions into a computer to compile a book; Can make simple slides and FLASH；; You can also chat online and play interactive games. Information technology can help me do countless things, which makes me have an indissoluble bond with computers. Although I am very nervous about my study now, I turn on my computer every day no matter how late. One is to review my information technology, and the other is to relax when I am nervous.
Information technology has become a tool for my entertainment. In addition, it is a good helper in my study. I can go online to find answers to questions I don't understand.
Especially after my mother bought me an electronic dictionary, information technology played an important role and made the electronic dictionary my private "teacher". I love information technology, and I hope it can bring happiness and convenience to everyone.
2. Composition on the topic of information This week, under the leadership of the class teacher, we studied the comprehensive study of "Into the Information World", which made me understand that information is everywhere, whether in class or outside class.
In class, what the teacher teaches us is knowledge, not information; On campus, listen to the school leaders, this is information; After class, watching TV, surfing the Internet and chatting with friends are also information. ...
As early as 2700 years ago, our ancestors invented several ways to convey information-bonfires. The bonfire, commonly known as "wolf smoke", is a tool burning with dried wolf dung as fuel, which is mainly used to transmit military information. Another way-the post office, the information transmitted is absolutely accurate. In modern times, science is more developed. In the 1930s, Morse invented the telegraph. Later, Bell invented the telephone, which made information transfer faster. 1984, with the birth of the first multi-coal computer, people embarked on the "information superhighway" from 1993. Nowadays, with the rapid development of computers, there will be a new generation almost every ten years, which makes people transmit information more quickly and conveniently.
2 1 century is an information world. Let's learn knowledge well and create a better tomorrow.
Smoky, dreamy feeling ... this is a world of colors: purple butterflies dance, fragrant, light and soft; Layers of ripples, rippling crystal rain halo, smart, clear; The air will not solidify, and the afterglow of the sunset will pass through the cicada, through the purple crystal cave, break the silence, and flash out seven-color rainbows, all of which are explored from the wonderful and beautiful light world.
Light can be divided into visible light and invisible light. Let's talk about visible light first.
Light lets us see a colorful and beautiful world, and light lets us see beautiful and gorgeous meteors. Meteors are instantaneous sparks, and only light can make us see them. Light not only gives us visual enjoyment, but also has many applications in life. Green plants can use light to carry out photosynthesis and promote plant growth; When we walk on the road at night, the moonlight can illuminate us; Solar cookers can use sunlight to boil water for cooking; Whenever people sweat, they will take a bath with a solar water heater. Medical light also plays a role: doctors in hospitals operate under shadowless lights when performing operations; When the otologist examines the patient's ear canal, he wears a front lens to focus the light in the ear canal. With the rapid development of science and technology, light has been widely used, such as laser ranging, collimation, optical fiber communication and laser surgery; Navigation lights can be used to guide ships and planes. In fact, we ancients were also good at using light. For example, Mozi and his students did the earliest pinhole imaging experiment in the world. We ancient people used ice lenses to draw flames from the sun.
There are also invisible lights, such as infrared rays, ultraviolet rays and x-rays. What are the applications of invisible light? Infrared can be used for remote control and satellite remote sensing photography, and infrared night vision device can be used to see the enemy's activities clearly in the dark; Ultraviolet rays can sterilize us. For example, ultraviolet rays emitted by bask in the quilt, "black light" can trap pests. Baby's sun exposure can make the skin produce vitamin D; X-rays can be used in human perspective. ...
If there were no light in this world, we wouldn't know that light has so many uses. If there is no light in this world, we will live in a dark and colorless dream forever. If there were no light in this world, we wouldn't appreciate the colorful flowers and gorgeous lights on the stage. ...
But light is not beneficial and harmless. If we are overexposed to the sun for a long time, we are prone to skin diseases. Strong light hurts the eyes easily. For example, the light during electric welding is very harmful to people's eyes. In cities, the glass installed on buildings is prone to strong reflection. It is easy to cause all kinds of light pollution. At night, strong light will affect people's sleep and even change the rhythm of living things.
To sum up, we can see that "lightness" has both advantages and disadvantages. We should make full use of the advantages of light and avoid its disadvantages.
In the colorful world, users linger. The colorful life is unforgettable. And "light" is so magical and beautiful. Let's enjoy the beautiful scenery of the world.
-Into the bright world
Let's connect them. I don't know if it is the best answer.
3. Facing abundant information, write 800 words to face abundant information.
2 1 century is the beginning of the information age. Facing the situation of knowledge explosion in today's society, how should we teenagers deal with it?
First of all, we must selectively draw information. Take the mixed network for example, we can use it to raise ourselves to a new height, or it may fall into an endless abyss. Everything depends on whether we can accurately distinguish their nature, avoid the parts that are not conducive to our physical and mental development, and learn the beneficial information instead. The same search website, some people use it to find information and broaden their horizons, some people use its massive information to satisfy their bad hobbies, or abandon real life because they are addicted to it. In the face of massive information, we should have the right to choose and steer in the vast ocean of data.
Secondly, we should treat this information rationally. In this era of knowledge explosion, we tend to get lost in it, lose our own views and go with the flow. At this time, we need to remember that information is an adjunct to support our views, not all of us. Seemingly rigorous scientific conclusions may change every day, not to mention the direction of rumors. A slight change in the narrative of the same thing will show a completely different attitude. Only by putting forward your own opinions from the heart-even if they are proved to be wrong in the end-will you not lose yourself in today's society.
Finally, learn to turn decay into magic. As mentioned above, information is an adjunct to support our views, but this does not mean that it is extremely cheap at any time. Once we have the ability to extract information accurately, we can turn it into a part of our own point of view and give it real value. Modern rich information is like a horde, and a group of counter-revolutionaries may destroy a period of history. Proper command can make a dynasty.
A screen is the epitome of the information age. In the torrent of time, we should integrate into this era and become this era, rather than being controlled by it.
Faced with a lot of information
With the continuous progress of the times and the rapid development of science and technology, the network is more and more integrated into our lives. Buying computers has become a trend. Computers have become an indispensable part of our lives.
I remember when my family bought a computer, I was only in the third grade. At that time, I was still superficial about computers, only knowing that computers could bring us convenience, but I still knew nothing about how to operate computers. Not to mention surfing the internet.
With the growth of my age, under the guidance of my father and the school computer teacher, I began to study with the mouse, then I learned to type, and then I went online. Maybe it's the interest. I'm a quick learner. In less than two weeks, I have been able to operate the computer simply and search things on the Internet freely.
After a period of use, I gradually found that the network is really amazing. You can know what is happening in the world with a key in your hand. No matter whether there is knowledge in the book or not, as long as you want to know, as long as you "Baidu" on the Internet, everything will come out. More importantly, it used to take two or three days or even longer to send a letter, but now with the Internet, all you have to do is send an email. Even if the other party is on the other side of the ocean, it can be done in a few seconds. The internet has so many benefits, of course I won't fall behind.
Now, I find myself inseparable from the Internet. During the holiday, when I encounter problems I don't understand, the first thing I think of is to check online. When I am tired of studying, I will go online to find some games to relax, and of course I will go to QQ to chat with my classmates. At the request of my father, I will often go to Xinhuanet and People's Daily to pay attention to major events at home and abroad. For example, the recent 7. Wenzhou extraordinarily serious railway traffic accident, Norwegian shooting and bombing, and "Jilong" diving into the bottom of the sea to set a new record in history ... I know everything I need to know, and I know everything I shouldn't know, so I can be called the host of my family's News Network. Even my mother will give me three points! The most important thing is-my dad asked me to write a composition or my life feeling every day, and then post it on my blog! He said that writing in this way could arouse my interest in writing. Of course, I will still be lazy. Between writing, I often go to QQ space to sort out the games in my space!
Although the Internet has so many conveniences, not everything on the Internet is good. For example, some bad games, I am determined not to touch. Other children will lose control of themselves, indulge in it, lose control and neglect their studies, which is also undesirable. Therefore, in the face of the network, we must be our own master and master the sense of proportion.
The network has enriched my after-school life and made my life more substantial and colorful!
I know how to get information. When I was a child, I was very naughty and often played pranks. Once I even had cosmetic surgery on one of my white shirts, and made it into a "black and white match" with a brush. My father was very angry and said, "Boy, if you don't clean this shirt today, you won't be able to eat." What should I do now? First I washed it with washing powder, then I washed it with soap, and there was no improvement. I felt hopeless, so I started a new prank. I spilled a handful of salt on my clothes. At this time, my father came, and I pretended to rub my clothes to avoid my father's scolding. Secondly, I expect a miracle. My feet are numb after rubbing my hands for more than half an hour. I took out my clothes and looked, hey! A miracle happened! The ink disappeared and my shirt turned white again. I took my clothes to get my reward, and a table of food was placed in front of me. I wolfed it down, but my father kept staring blankly at his shirt. He wanted to educate me to study hard, so I wiped my clothes clean and his plan fell through. Later, I learned from books that the chemical name of salt is sodium chloride, which is a kind of crystal. It can be used not only for seasoning, but also for removing stains. It can remove stains from clothes. Salt is also a good fire extinguishing agent for home use. Under the high temperature fire source, salt can be quickly decomposed into sodium oxide, which absorbs free radicals in combustion through chemical action, thus inhibiting the combustion process. Granular salt is an effective fire extinguishing agent. Because of its high particle content, it absorbs heat and expands at high temperature, destroying the shape of the flame, and at the same time, endothermic reaction dilutes the oxygen concentration in the combustion zone, so it can quickly extinguish the fire. It seems that there is learning everywhere in life, as long as
5. Write an 800-word composition about information technology for Senior One, and draw up a good bonus topic by yourself.
I am a lucky person, living in the 2 1 century with rapid development of high technology. I walked on the flat asphalt road, shuttling between rows of skyscrapers, and the cars around me flew by, dazzling me. Information technology has brought convenience to our life. I like information technology, and I prefer it to come into my home.
Among many information technologies, computers are obviously the best among all sentient beings, and they are favored by people and have entered thousands of households. I couldn't resist the temptation of high-tech products and invited high-tech to my home with a novel and exciting mood.
This computer has a beautiful appearance and complete functions. It attracts me like a magnet. I can't wait to turn on the computer and enjoy the high-tech addiction. This computer is the latest from Tsinghua Tongfang, and it is easy and quick to boot without any troublesome procedures. The computer started to start, and soon, what was presented to me was the desktop of the computer, on which nearly 20 functions were clearly arranged. All I have to do is move the mouse and click twice, and I can quickly open the windows of various functions. There is also a small "Start" button in the lower left corner of the desktop, after which more programs and functions will appear.
To my great joy, my computer has been connected to the broadband network, and I can browse all kinds of web pages quickly. When I turned on the Inter connection system on the desktop, I immediately entered the website of our school with lightning speed, pressed the Enter key and waited in fear and trembling. 1 sec, the webpage of Wujiang Experimental Primary School immediately appeared on the screen. I am dancing with joy. On this website, I saw a lot of moral education knowledge about our school, the latest news and school profile, which really opened my eyes and made me happy.
Later, I logged on several news websites. I felt extremely proud when I saw the news that Chinese astronaut Yang Liwei had successfully returned to Earth on the Shenzhou 5 spacecraft. Although I have heard this exciting news for a long time, I am still as excited as I just got the news, because this is the first time for me to surf the Internet with my own computer, and it is also the first time for me to get information online. At this moment, this little computer became sacred in my eyes. It is the messenger of information, which makes the originally vast world small and panoramic. It is even better than TV, so that my scholar can know the world events without going out. "What a magical computer!" I can't help sighing.
What makes me most happy is that I have exercised my writing ability online and improved my composition level. In order to stimulate our interest in writing, the editor creatively put forward a scheme on "Creative Writing Network for Primary School Students", which allows us to accumulate points (a kind of online electronic money) by publishing compositions online. Whoever has an excellent composition will get high marks. When you accumulate to 500 points, you can exchange them for a composition magazine. As long as you tell the editor the address, it will be delivered soon. I've got one, and I'm redoubling my efforts to get the second one!
Now, this computer has been in my home for some time. It has brought endless fun to my life and study and benefited me a lot. It is like a diligent correspondent, connecting the whole world and providing me with information transmission at any time; Also like a learned teacher, he is proficient in everything and instills knowledge into me; It is also like an encyclopedia, in which any knowledge can be found. The emergence of this advanced equipment is attributed to information technology, and its birth has brought unparalleled advantages to people's everything. Without information technology, computers can only be a beautiful and illusory dream today. Today, as a new century, I enjoy the convenience brought by information technology. I will better inherit and carry forward information technology and open up a more brilliant new world for future information technology. I can't help shouting:
"Information technology, how wonderful!"
6. Write a composition with "network information", about 400 words. Nowadays, the network has become an indispensable tool for human beings, and it has two sides. Some people make progress for it, while others commit crimes for it.
I watched a lot of videos about the harm of Internet addiction, and listened to the evil deeds of many networks, so I couldn't help shouting for the network. Both sides of the network depend on who uses it. People who use it well have many benefits; Taking advantage of disadvantages can also lead people astray. In my opinion, the network is actually nothing, so you should pay attention to it when using it, and you won't be fascinated easily. I am also addicted to the internet. I don't concentrate in class every day, and I always want to play computer. But once time cooled down, my internet addiction changed unconsciously. If I use it as a learning tool for a long time, I will get tired of the internet and won't want to play. During this time, I wandered between watching TV and playing computer. Once I lose interest, my life will lose interest, but you can always feel happy in my study. Unconsciously out of the network, only to find that there are many things worthy of our attention in life, we can not indulge in one. With these, I am not addicted to the internet and will control it properly.
I hope people who are addicted to the internet can use my method appropriately, which may be helpful to you. I wish all the students who are addicted to the internet in the world can pull back from the brink and get out of the online world as soon as possible!
7. Modern information has changed our lives. Information transmission has changed our lives. Internet is our best friend, our most beloved teacher and most dedicated boss. The internet is a double-faced spy, which will bring us both advantages and disadvantages.
The benefits of the internet
If you are bored at home, you are fine and lonely. You can find your bosom friends online and chat with them, and you will be happy and cheerful in a short time. If you are tired of chatting and typing, you want to relax. Turn on QQ music, play a melodious song and water the plants on the farm. If your academic performance is not good and you are worried about being scolded, you can learn from famous network teachers to save you from "medicine" and "illness". If you can't find a job and sigh all day, you can find a job online ... The Internet has given us happiness, knowledge and work.
Disadvantages of the internet
Although the network has many advantages, it is a veritable eyeball and emotional killer. It is said that 75% of the people in the world are addicted to games every year, and 25 to 30 of the 50 primary and middle school students are nearsighted. People are crying, but they are snickering online! The emotional killer is even more horrible. When you play too much computer, because of radiation, some people's eyes are so stupefied that they forget friendship, family, anything and are not interested in anything. All the joys and sorrows have disappeared, and the whole thing is like a "biochemical robot". Is the internet. There are advantages and disadvantages, just like an Okumo crawling around the earth, but I believe that as long as you believe in it and make good use of it, you won't let the disadvantages climb on you.
