The magical "angel"---Computer2007-12-10 19:46:38 By: Zhu Xiaohe Computer He is a magical guy who can help people do many things and is very efficient! It is an assistant given to us by God. With computers we can do a lot of things! It can help us look up information. If we don’t know anything about study, we can also ask it for advice. It is an "angel". The computer is always with us. It is giving silently instead of asking for it. "Giving" will always be It is more pleasant than "getting". The above sentence was written by Gorky in a letter to his son. The above sentence can completely describe the computer. It is such an "angel"! ~ Let me talk about myself first. Before I touched a computer, I was like a headless fly who didn’t know how to write words. Of course, I knew that looking up a dictionary was a good way, but I felt bored just picking up a dictionary. Ever since I After seeing the computer, many words can be seen by typing their pinyin. I also learned from the computer that looking up the dictionary has many benefits, so I got used to looking up the dictionary! ~ Many adults don’t approve of their children playing with computers. There are only a few reasons. ① They are afraid that their children will have poor eyesight. ② They are afraid that their children will not do their jobs and lose their ambition by playing with them (my mother is also afraid that I will play with a few). But computers are not necessarily It will only bring disadvantages, but there are also advantages, such as: checking information, listening to music, reading news, creating your own web page, and you can buy and sell things on the Internet without going out, and you can also have door-to-door delivery. Remember to do it during the summer vacation. When I didn't know a few English and proverbs, I asked my mother, but what she told me was - my mother couldn't do it either.
At this time, my mother told me to turn on the computer to check... I was only 1 year old at the time, and I didn’t know how to search for information or how to find the most correct information. My mother told me that you You can go to Baidu to find it. Everything is there, but at that time I didn’t know how to write Baidu’s website address, so I asked my sister. After asking, I knew that Baidu’s website address was: As soon as I knew it, I went to look for what I wanted. Information, as expected, my mother found the correct answer. I immediately copied the answer. That day, I checked everything I didn’t know and didn’t know. I also checked the things I didn’t know. .Now I know pretty well! ! The "angel" God gave us is my "good friend" computer. I am very grateful for the convenience it brings to us. The Fuyun Fairy computer from Class 2 (2) of the Computer Teaching and Research Office of Hangzhou City, Zhejiang Province is now with us. We have a close relationship: we need a computer to find information, we need a computer to play games, we need a computer to chat online, we need a computer to understand information... In short, we can no longer live without computers. Computers contain many contents, among which the international Internet has spread all over the world.
It is also called inter, and its original source is a military network of the US Department of Defense. When I originally designed it, I did not think of extending the network to the whole world. I simply hoped that if a nuclear war broke out one day, there would be a network that could still travel around the world after being attacked by a devastating attack and have the ability to quickly restore smooth traffic. .
In the 1970s, the U.S. Department of Defense began the DARPA project and began to build high-speed and flexible networks. The key point was that if the network between the United States and the former Soviet Union was disconnected, data could still be transmitted through other Country detour to reach destination. The result of this project was ARPANET.
Later, as the Cold War thawed, ARPANET was slowly opened to civilian use. However, based on military security considerations, the United States also established the National Science Foundation and established NSFNET, which is responsible for global civilian network exchanges.
This is the INTERNET of the United States.
Although the United States has many rights over the Internet, for the development of science and technology, the United States itself does not charge a large amount of royalties for any behavior on the Internet (because the international Internet was researched and developed with money from the United States), so many Research institutions have been able to participate in the research and development of Internet technology and services at a very low cost, and Internet has thus been able to develop into the world's most extensive network.
Apple and computers are two completely unrelated things. What is the reason that connects Apple and computers? In the early 1970s, microelectronic computers (microcomputers) came out. Because of their complete functions, small size and flexibility, they attracted a large number of teenagers who love electronic technology. Near Silicon Valley, the computer base in California, in the western United States, there are two electronics fans who are only 18 or 19 years old in a small town called Cappatini.
The older man is called Steve Job. He makes a living by helping in the apple orchard on the farm while studying in college. The younger one is named Steve Wozniak. He loves music and plays with various electronic instruments. He is also an amateur in electronic technology.
The two had similar interests and became a pair of good friends who share the same brotherhood. In 1974, some local electronics amateurs voluntarily organized a club to build microcomputers by themselves.
Job and Wozniak participated enthusiastically. They used an abandoned garage owned by Job's father as a studio and began to trial-produce microcomputers.
They first tried to install the microprocessor into a simple microcomputer, and then connected it with a television and keyboard to form a microcomputer system. The operator only needs to press the keys on the keyboard, and text and simple graphics will be displayed on the TV screen. This achievement was welcomed in the club, and then they trial-installed a small batch for public sale. Unexpectedly, it was suddenly popular. Ordered 50 units.
So these two young people started a microcomputer company. In order to commemorate Job's work-study years in the apple orchard, they named this new type of microcomputer "Apple II" (Apple II), and the initial trial microcomputer was called "Apple Type I” (Apple I).
This is the origin of Apple Computer. Later, Apple-type microcomputers quickly became popular all over the world, and the Apple Microcomputer Company, headed by Job and Wozniak, developed into an international enterprise with more than 4,000 people and established many branches around the world.
There are almost no computers today that are not equipped with a mouse. Without this cute little thing like a mouse, it would be impossible to use a large number of various software well. So, where did the mouse come from? The formal name of the mouse should be "display system vertical and horizontal position indicator", and it is also called so in the invention patent. 2. How to write an essay introducing computers
With the development of science and technology, computers have entered the lives of many people. Last year, I also got a computer, which brought me a lot of convenience, increased my knowledge, and broadened my horizons. The computer is divided into three main parts, the monitor, the host and the keyboard. The monitor is a large screen, like a television, that displays a variety of icons. The host is the "heart" of the computer. It has two eyes, one big and one small. One starts the program and the other restarts the program. The keyboard that contributes the most is the keyboard, which contains 26 English letters, 4 direction keys, 10 numbers, and some indispensable function keys. They each stay at their posts and serve their masters. The computer also has a small tail, which is the mouse. The mouse is used to issue instructions, and the monitor will obey its instructions. This is the magical function of the computer.
Computers, also known as electronic computers, were invented by scientists after years of research. After several generations of "multiplication", electronic computers have become "versatile" computers. Computers can access the Internet, and the content on the Internet is even more colorful. You can find your favorite books and articles in the library.
In the chat room, I can chat with netizens at any time, talk about the topics I want to talk about, make more friends, and understand other people's personalities
Don't look at the computer's physical strength, but if you encounter its nemesis - electronics Virus, the consequences will be disastrous. However, you can open 360 anti-virus software and the virus will be eliminated, just like giving medicine to a patient. Regardless of the computer's physical hardness, if it encounters its nemesis - electronic virus, the consequences will be disastrous. However, you can open 360 anti-virus software and the virus will be eliminated, just like giving medicine to a patient.
Just follow this introduction. There are many articles on the Internet. 3. Notebook writing
In my bookcase, there is a small notebook, which is my diary. , in the eyes of others, that book is not rare, but it is very precious to me, because at least I let it record a complete story.
When I was young, no matter whether I was happy or wronged, I would confide in my diary. Only the diary remembered my things. Especially when I am very excited, I want to find it immediately and tell the secret in my heart.
Once I was bullied, and I wanted to write about the situation immediately to vent my dissatisfaction. When I got home, the scene at that time appeared in my mind, and I quickly wrote it down.
After I finished writing, I felt much better, but I also felt that the words were used very dryly, and it didn’t look like a good article. (Wujiang Zhenze Yilong Redwood - Yilong Literature) I believe that no matter what hardships I encounter in the future, I will stand upright and never bow my head. As long as I write, even if it is to keep a running account, I will not Give up the journal.
When I grow up and look back at my childhood diaries, I will definitely feel nostalgic for my current childhood life. 4. How to write an explanatory essay about computers
Getting closer to computers. Computers, which were regarded as mysterious by Chinese people a few decades ago, have gradually unveiled their hazy veil and entered the homes of Chinese people.
Computer is another name for computer. Because of this, people often associate it with addition, subtraction, multiplication and division, which makes us, students who have studied hard for sixteen or seven years, full of expectations for it.
When I was in primary school, computers used written arithmetic. When I was in middle school, I learned abacus and reached the highest level of "seeing a few numbers without dividing them by nine." For speed, we had to use a logarithmic slide rule with poor accuracy. Participants were asked to perform calculations with high precision, and a hand-operated computer was used for multiplication and division calculations.
This kind of hand-cranked computer lives up to its name and is specially used for "calculations" of multiplication and division. Although it was very noisy to use and its speed was far inferior to the calculators that are widely used today, it was a rare "treasure" at the time.
In the spring of 1979, the secretary of the party branch in my hometown saw me using a hand-cranked computer at work. After returning to my hometown, he really praised me and said that I could shake that wheezing foreign thing so well. Whispering, you can calculate a number of hundreds of thousands in the blink of an eye, it's really amazing! The first computer knowledge enlightenment education for me came from relevant magazines in the 1960s and 1970s. In an introductory material about applied computers, I saw an introductory article about using computers to prove the four-color theorem outside the graph.
The four-color theorem is a truth recognized in the geography community. It states that only four colors are needed to draw a map, but the necessary proof was lacking at the time. With the help of computers, it took more than two hours to prove it.
If manual proof is used, it will really require generations of successive generations. In the mid-1980s, computers, with their inherent mystery, entered the doors of some government agencies in provincial capitals. People welcomed the arrival of the first batch of computers like a new daughter-in-law.
At that time, many units stipulated that computers must be installed in special rooms, with wooden floors and appropriate elevation; operators must wear overshoes to enter, and their hands and faces must be clean; etc. At the leadership meeting of a certain unit, there was an oral decision that non-staff members were not allowed to enter the computer room to prevent "virus" infection.
The widespread application of computers is a manifestation of social progress. People's application of it started from general operations such as delivering reports and printing files, and gradually expanded to all aspects of application in the industry. The work efficiency is getting higher and higher, and the magic of computers is more and more displayed.
Our highway industry uses computer graphics, which eliminates many troubles such as base drawings, pencil drawings, tracing, and printing, etc., and is extremely fast. Moreover, computer graphics have high precision and beautiful pages, making them very popular among users.
When people conduct business exchanges now, they no longer need to print and mail materials. They only need to send an email, which is convenient and trouble-free. A USB flash drive weighing tens of grams can record considerable and rich information and become a good helper for the carrier to use at any time.
Learning to use a computer requires hard work, otherwise it will be difficult to uncover its mystery. In 1998, when I was still on the job, my original employer equipped me with a computer, which gave me the opportunity to get in touch with and learn to use computers.
At that time, I was already a clumsy fifty-five years old. In order not to leave lifelong regrets, I started learning computers like a primary school student, and it has been seven years.
In the past seven years, although I have never stopped learning and operating, and I can’t remember how many masters I have “obeised”, I am still not very proficient in fingering, not to mention that there are still many fields that I have not yet explored. Computers will always be a mystery to us if we don't make the effort to explore them in depth.
Only then did I understand why people should "live and learn". Computers store rich knowledge and entertainment content.
There is nothing wrong with using computer games, but it should be done in moderation. There is an old saying that opening a book is beneficial, which means that when you read, you will always gain something.
Nowadays, it is not impossible to say that "turning on the computer is beneficial." In your spare time, when you are bored, it is also a kind of gain to turn on the computer and play, practice your fingering, and stimulate your intelligence.
Before the Spring Festival, I suddenly got two laptops. One was purchased and the other was "gifted" by my naughty little disciple: "Please put a laptop on the table. Then put your chin on the notebook. Okay, this is my Spring Festival gift to Master - notebook pad."
Computers and computer pads both make me happy. I believe that just like the popularization of color TVs, the popularization of computers will not be too far away, and it will be faster than the popularization of color TVs.
2. Possess a large amount of information. Expository texts are mainly used to impart knowledge and communicate situations. The former must understand the relevant knowledge, and the latter must master the situation.
This requires reading more and accumulating more. For example, when writing "Snowflake's Self-Report", the scope of explanation is very wide. You can explain the formation process of snowflakes, you can explain the role and harm of snowflakes to the growth of crops, you can use snowflakes to explain changes in the weather, etc.
Which aspect to focus on mainly depends on which aspect you are most familiar with and have the most information. 3. Grasp the characteristics of things.
To introduce something, we must grasp its main characteristics and explain them in detail, and briefly explain its secondary characteristics. For example, when writing about a frog, it should be briefly described as an amphibian, and its characteristics of being good at catching pests should be described in detail.
4. Arrange the structure reasonably. The structure of expository essays is mostly arranged according to the laws of things themselves, and can also be written according to the laws of people's understanding of things.
Judging from the laws of things themselves: the first is to arrange the levels according to time, such as "The Self-narrative of a book"; the second is to arrange the order according to the spatial position, such as "The Self-narrative of the Oriental Pearl"; the third The first type is a hierarchical explanation based on the category of things, such as "The Self-Description of Bacteria"; the fourth type is to explain things layer by layer from cause to effect or from effect to cause, such as "The Self-Description of a Cigarette". Judging from the rules of people's understanding of things, some more complex or unfamiliar things can be explained by starting with phenomena that people are familiar with and explaining them from the shallower to the deeper.
Any explanatory text that is divided into levels according to time, space, and category is best to summarize first and then divide or divide first and then summarize. There is a complete summary explanation that can facilitate the reader to see the whole picture. 5. Lively explain the language.
This type of expository essay cannot use purely scientific language, but must use a literary and artistic style. Because I am speaking from my own experience, I cannot speak in a rigid manner, but should try to be as harmonious as possible.
To make the language vivid, you can intersperse vivid examples, use metaphors, use inspiring doubts, and quote poems. 5. High school Chinese language accumulation, how to write in a notebook
I am a high school Chinese teacher, let me talk about it based on my work experience:
First of all, we must correctly understand the meaning of Chinese language accumulation. Chinese language accumulation is not, or not all, recorded in a notebook. Accumulation is not an isolated, mechanical memory activity, but the interconnection of memory and understanding, emotion, appreciation and other links, creating a new knowledge structure, a process of reconstruction, and understanding the text. The specific meaning of the content, identifying the specific characteristics of the content, and understanding the specific connections between the content are the prerequisites for effective accumulation. If you ignore students' understanding, perception, and experience and only emphasize recitation, you can only get twice the result with half the effort. The ancients' "emphasis on reading" must also be more "emphasis on understanding."
Secondly, when accumulating in notebooks, you should pay attention to using loose-leaf books, and separate one type of content from another. Organize and categorize after a period of time. For example, the arrangement of words and sentences. You can sort out the new words you usually learn, as well as the words you made mistakes in exams. In addition to words, you can also write down idioms and sentences containing idioms to experience the usage of idioms. This will be very beneficial to your Chinese language accumulation and exams. Then there are the ancient poems and essays, which are mainly for memorizing extracurricular ones, but also for mastering the in-class ones. The extracurricular ancient poems and essays in this book are mainly an expansion. There are also beautiful article paragraphs. For example, if you read an article and think you like it very much, you can excerpt some paragraphs. There are also famous quotes and aphorisms that can also be excerpted.
In particular, I would like to remind you that when you say there is nothing in your mind, I suggest you carefully read "Water Margin" and "Dream of Red Mansions" among the four famous classics, and gain a good understanding of them and read them yourself. This is the most important accumulation method.
I hope you are satisfied! 6. Composition: How to write the computer of the future
The biggest advantage of this kind of laptop is that it integrates digital TV technology and adds various functions such as shopping, learning, and entertainment. As soon as you turn on the computer, icons such as TV, storage, shopping, learning and entertainment will appear on the screen. You can watch TV programs from all over the world by clicking on the TV with the mouse. After clicking Save, just take a photo of the file you want to save on the monitor.

What will the future world look like? What will the computer of the future look like? Let me tell you!
In the near future, there will be a kind of computer. It has strange functions and has seven main characteristics. What are the characteristics? Let me tell you! Its first feature is that it does not operate with hands, just say it; the second feature is that it does not have a bulky body, its shape is just a headset, with computer glasses attached to it, you will be very comfortable wearing it; The third feature is that it can be folded. If it is not in use, it can be folded and stored. It only requires a box of one cubic decimeter. The fourth feature is that it can make phone calls and unlimited Internet access. The fifth feature is that it can be used as a radar. , it can detect what is approaching you, it is launched by satellite; the sixth feature is that when it is adjusted to the in-car state, it can detect all the police and cameras within nearly one kilometer. If you find that it lights up, you Just drive slowly to avoid being fined for speeding by the police or being photographed by the camera. It is also launched by satellite; the seventh feature is that it can watch unlimited channels from all over the world.
With this kind of computer, how colorful life will be! It can bring many conveniences to people. However, it requires people to invent it. Whether it is ten years, twenty years, thirty years... no matter how many years, I believe it will be invented.
Things in the future must be wonderful. Maybe more advanced and more perfect computers will be invented soon. 7. How to write a computer readme
