Write a composition on the topic of mobile phone or computer software.

1. Write a composition around mobile phones and computers. In modern society, computers have become an indispensable part of people's lives.

A computer consists of a host computer and a display screen. The host computer includes CPU, motherboard, hard disk drive, CD-ROM drive and memory card.

The function of the display screen is to display and adjust the picture. Computers also have keyboards, mice and speakers.

Many programs are installed in the computer, including "My Computer", in which files are stored and hard disks are installed.

My Documents contains * * * pictures, * * * music and so on. The recycle bin is used to clean and recycle unnecessary files.

The computer is also equipped with many convenient typing programs, such as "Jinshan characters", which can be mixed with pictures and texts and inserted into tables. Anti-virus software must be installed on the computer to ensure that the computer in the studio is free from viruses.

With a computer, you can query a lot of knowledge online, browse various websites, check all kinds of information and news, send and receive emails, chat online and many other functions. The computer is like a knowledgeable scholar, answering people's doubts about work, life and study.

How inconvenient it would be if there were no computers in people's lives. Computers have brought a lot of convenience and fun to people's lives.

With the development of science and technology, computers have entered many people's lives. Last year, I also had 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 just a big screen, like a TV set, displaying various icons. The mainframe is the "heart" of the computer. It has two eyes, one is big and the other is small. One starts the program and the other restarts it.

The biggest contribution is the keyboard, which contains 26 English letters, 4 direction keys, the number 10 and some indispensable function keys. They stick to their posts and serve the host.

The computer also has a small tail, which is the mouse. The mouse is used to give instructions, and the monitor will listen to 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 "reproduction", electronic computers have become "universal" computers. Computers can surf the Internet, and the content on the Internet is more colorful.

You can find your favorite books and articles on the bookshelf. 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. Although the computer is physically hard, if I encounter its nemesis-electronic virus, the consequences will be unimaginable.

But you can turn on 360 antivirus software, and the virus can be eliminated, just like giving medicine to a patient. At present, science and technology are developing rapidly, and I firmly believe that computers will be one of them in the next few years.

2. Write an article about smart phones. Speaking of smart phones, it is a household name. Smart phones provide convenience for our lives.

For convenience, since it has made such a great contribution, I will introduce the mobile phone to you.

Smart phones provide users with enough screen size and bandwidth, which is not only convenient to carry around, but also

It provides a broad stage for software operation and content services, and many value-added services can be used in this respect.

Expand, such as: stocks, news, weather, transportation, etc. These are most smart phones.

So what other functions do smartphones have? The term smart phone is mainly a needle.

The "feature phone" itself does not mean how "smart" the phone is;

On the other hand, the so-called "smart phone" is a mobile phone that can be installed and installed at will.

Uninstall the "small computer" of the application software. After sorting out and analyzing the survey data, I found wisdom.

The functions of the mobile phone include: normal phone calls, text messages and other mobile phone functions.

4. Write a composition with mobile phone and computer. One day, the host joked with friends on his mobile phone and played games on his computer. In the evening, the host said, "What a happy day!"

Hearing this, the computer proudly said, "Haha, mobile phone, the host is so happy today. I must make the host happy." The mobile phone stared at the computer and said unconvinced, "Do you think this is all your credit?" Not necessarily, I let the host talk and laugh with his friends, so the host will be so happy, and ~ ~ ~ ~. ""Shut up, "the computer is getting impatient." What are you, a mobile phone, trying to compare with me, in ten years. "Unplug the angry mobile phone by hand, ah! The computer screen is gone as soon as it is brushed. At this time, the mobile phone saw it and said, "Haha, what happened to the computer?" The computer said, "Do you care? This is my housework with my mobile phone brother. "

Everyone has his own strengths and weaknesses. We should respect each other and live in harmony.

Write an explanation for your computer or smartphone. The mobile phone that everyone is using now is called smart phone.

So what is a "smart phone"? It refers to a mobile phone with an independent operating system like a personal computer. Users can install programs provided by third-party service providers, such as software and games, and access wireless networks through mobile communication networks. In fact, I think smart phone evolved from PDA, which is a scientific combination and sublimation of traditional mobile phone and personal computer, but it has obvious advantages compared with traditional mobile phone.

Smart phones have brought a lot of convenience to our lives. It can shop online like a computer.

I remember last year, the teacher asked us to buy a book. Dad went to several bookstores nearby and found nothing. He had to drive for half an hour to the Xinhua Bookstore in the west of the city to buy it. It took a whole afternoon to go back and forth. This year, my mother installed Alipay on her smartphone and clicked Taobao several times. Many books are on display in front of us, and the prices are also discounted! I got some brand-new books the next day without leaving home. It's really convenient and affordable! Besides shopping, mobile phones can also show us the way.

This summer vacation, I reported on the Internet that I participated in the freestyle training class in Bao Yugang Swimming Pool, but my mother and I haven't been to the swimming pool yet, and we don't know the location, except that it is near the intersection of Tianmushan College. After we got off at the intersection of College by bus, we walked along College Road for more than ten minutes without the sign of swimming pool. At this time, my mother thought of the mobile phone and took it out to look for the map, only to know that we were going in the wrong direction and going further and further. In fact, it is quite close to the place where we got off. Thanks to this smart phone, it would really be a "world of difference".

Smartphones make our communication more convenient. It can chat online like a computer, but it is more convenient than a computer because it can communicate with each other anytime and anywhere.

In the "hand in hand" activity organized by the school, I met Jiang Dingrou from Fengshuling Primary School in Chun 'an. Usually only through letters, slow, lack of color, because letters only have black handwriting. I learned her QQ number this year and chatted online with my mother's smartphone. We finally saw each other's voices and smiles.

After that, we often talk about the study and interesting things in our class through smart phones in our spare time. Two people are often "moved" by each other and laugh. In June this year, my six-year-old cousin, who is far away from home, participated in the martial arts performance of the District Children's Group and won the Excellence Award. At the moment when she received the award, my mother and I were on the way, and my mother had good news from her on her smartphone.

There will be a video soon. Show it to me in an orderly way. Although hundreds of miles apart, we shared the joy of success together at the first time.

Of course, the development of smart phones will be broader in the future. Not only personal communication, information management, schedule, task arrangement, multimedia application, web browsing, etc. , such as: stock, news, weather, traffic, goods, application download, music picture download, etc.

It will also be an important means of "smart city" and "smart family". Realizing wireless synchronization can release all the functions of smart phones, and make a mobile phone a time management tool, a mobile office platform, and remotely control the TV, rice cooker, air conditioner and washing machine at home.

It's really good to think about trivial things in family life, such as washing and cooking, all done by mobile phone! According to my father, smart phones have been used in the military fields of various countries. Such as taking photos, positioning and tracking, inertial sensing, Bluetooth signal, electronic compass and other functions. Smart phones can be used for wireless remote control, that is, through the wireless signals of smart phones, you can remotely control your own micro drones and robots, and you can also take over other drones and robots to complete reconnaissance and monitoring tasks, and watch the video images taken by drones in real time on the display screen.

It can also be used for battlefield communication and reconnaissance as a battlefield situation awareness terminal.

6. Write a composition on the topic of smart phone. I will also use my super power to cross the white road of time and space and go back to ancient times to see what the diet and daily life of ancient people are like. I'll just look at how dinosaurs died out, so as not to make scientists angry with each other about this problem. More importantly, I have to see what plants and animals grew on the earth before the birth of human beings. I also want to see the incarnation of Confucius. Traveling in space, I also want to go to Huaguo Mountain to meet the Monkey King, and I will also go to Heaven to taste the elixir refined by the old man. Of course, I won't forget to study after I become a superman. I will make use of superman's super memory to achieve my achievements by going up a flight of stairs. Super-edition people love to fight against injustice, draw swords to help each other, learn astronomy, learn geography, travel in space, visit celebrities and come back. I really want to be a superman, a superman with infinite power.

7. Write a 300-word essay on the topic that I like smart phones. The development of modern science and technology is really changing with each passing day. Mobile phones have only been around for decades. Nowadays, mobile phones are no longer just calling and texting.

At present, people's lives are inseparable from mobile phones. The mobile phone that everyone is using now is called smart phone.

It is the product of the development of science and technology, which makes our life more and more beautiful and makes us full of hope for a new life.

At the same time, as the future of the motherland, we should redouble our efforts, study hard, always be ready to build our beautiful home, lead our life with wisdom, and let beauty stay in our home forever.

8. Talk about my understanding of smart phones and computers. Write a composition of 350 words. Nowadays, almost everyone has at least one smart phone or computer, and our life has proved this point well: in the past two years, only smart phones can meet the basic needs of digital life. But a few years ago, this was not the case. Even 20 1 1 and 20 12 smartphones are not powerful enough to meet our requirements for computers.

Due to the enhancement of processing power of mobile devices, the extension of battery life, the improvement of network speed and the increase of screen size, the era of mobile phones is getting closer and closer.

So, will we always need computers? At present, not everyone will always need it, at least some people no longer need it. We can use smart phones to accomplish tasks that used to require computers. Mobile phones can replace computers in a few years, which means that in the near future, most people will give priority to using mobile phones, and with the current development speed of the mobile industry, we will soon usher in the era of smart phones and computers.

At the same time, the global PC industry as a whole showed a downward trend. Some high-tech mobile workers have begun to replace laptops with tablets, but now large-size smartphones are also beginning to replace tablets. For many developing countries, the mobile phone may be their first computer and the only network device. In the next few years, high-end mobile phones will be able to handle 4K video tasks, immersive virtual simulation games, and some seamless docking processing tasks. As consumers, people like mobile phones very much. From a global perspective, mobile phones have basically become the main computing devices, and PCs have become the secondary computing devices.

Although the hardware and software of the mobile phone can technically handle the tasks assigned to the computer in the past, it still needs an adjustment period to change the mode of smart phone+notebook (or desktop computer) into a single mode of smart phone at once. More and more things can be done by smart phones, but for most people, it will not replace large devices equipped with keyboards. Unless smart phones can work like computers, digital cameras, video cameras, GPS navigation devices, MP3 players and DVD players, they will not become the main computing platform for most people. At present, it is not practical to use an external monitor and keyboard at work and a wireless network to connect TV at home, so it is not practical to use a mobile phone to fully meet the daily computing needs.

9. Write a 600-word composition on the topic "Mobile phone is the glory of mankind"-the rapid development of mobile phone information and communication technology after 20 years is amazing. What we think is incredible today may appear in real life tomorrow.

We can think infinitely about future communication. So, how wonderful will the mobile phone be in 20 years? In 20 years, mobile phones will have the function of "fingerprint identification". People should first input your own fingerprint sample into the mobile phone, click OK, and then click OK.

When turning on the phone, just touch the phone screen with your own hands. If someone tries to steal it, it will call the police; While discharging; When the alarm goes off ..... let the thief have no chance.

In 20 years, mobile phones will be as multimedia, light speed and small size as computers. First of all, it can connect to the Internet to watch TV, listen to radio, watch movies and listen to MTV. ..................

Not only that, if you get online, you can use it to study and play, just like a PDA, which is simple and easy to use. It is really "a scholar has a mobile phone and knows everything in the world"! Mobile phones can also shoot DVDs and send them by email. Mobile phones can also replace wallets. The mobile phone will be connected to the bank account, so there will be no need to "swipe the card" and prevent theft ... After 20 years, the mobile phone will be combined with the GPS satellite positioning system. Let you know where you are now and where you are. If you get lost somewhere, you can turn on the global positioning system, which will tell you where to go. Besides, the original things of mobile phones are indispensable. The mobile phone will be equipped with an LCD screen, which can see each other's every move during the assimilation process, and will also be equipped with an alarm. When you need it, it will do its duty, go forward and go forward.

It is also: various shapes, durable, elegant, cheap and magnificent ... Finally, I will tell you a little secret: this mobile phone absorbs carbon dioxide and releases oxygen. I will remind you to save water from time to time! How's it going? Not bad, huh?

10. Write an article and a narrative about mobile phones, with no less than 900 words. In the streets, shops and parks, the use of mobile phones can be seen everywhere. Indeed, with the development of wireless communication technology, more and more people use mobile phones. Mobile phones seem to have become an indispensable tool in people's lives. I selected ten households from my neighbors for investigation, and found that all the adults in these ten households use mobile phones, and some have more than one. Half of the children over the age of ten are equipped with mobile phones, and they all like them very much.

This year, my father also bought me a mobile phone. I am so happy that I take it with me when I go out, but a report in the newspaper the other day makes me nervous. The title of that report is "How Harmful Cell Phone Radiation is to Human Body", and it mentioned the harm of cell phone radiation to brain, eyes, heart and other organs. Foreign experts also suspect that a rare brain tumor and eye disease are also caused by long-term use of mobile phones. They also said that the legacy of electromagnetic radiation will continue to accumulate, and after ten to fifteen years, it is likely that there will be more cancer cases caused by the popularity of mobile phones.

Well, then, if we take our mobile phone with us, isn't it equivalent to taking care of a killer who hurts ourselves? I was so scared that I told my parents that we should stop using mobile phones. It's too dangerous to use a mobile phone. However, they say that as a communication tool, the convenience of mobile phone is unparalleled, and people can't avoid it, but we can find the right way to use it to minimize the harm of electromagnetic radiation to human body.

Since then, I have been surfing the Internet every day to find the right way to use my mobile phone. I really don't know when I look at it. I was shocked at first sight. As everyone knows, many practices that we have long been accustomed to are wrong, and some are even quite dangerous. For example, in summer, Amy's aunt will hang her mobile phone on her chest, and then the radio waves will quietly affect her heart and endocrine system; After dialing, we put the phone to our ear and waited for the call, but we didn't know that its radiation was about three times that of standby; Uncle likes to hang his mobile phone around his waist. After a long time, he may not be a father. Chatting on the mobile phone for a long time, always putting it on the pillow when sleeping at night, waiting for them may be the breeding of brain tumors ... these are chilling.

So, what kind of method is correct and effective? Combining my own feelings and relevant information on the Internet, I put forward the following suggestions:

1, don't hang your mobile phone on your chest, especially for people with cardiac insufficiency and arrhythmia.

Don't put your mobile phone on your waist or in your pocket. Put your mobile phone aside in the office, at home or in the car, and put it in your purse when you go out.

Mobile phone radiation is harmful to people's head. We should try not to put our mobile phones near our heads, and don't put them next to pillows when we sleep. We should put it 1 m away from ourselves.

When making a phone call or answering a phone call, it is best to put the phone away from your body and put it in your ear.

5, it is best to answer the phone with the left ear, because the right ear will directly damage the brain.

6. Don't make a phone call when there is only one battery left, because the radiation at this time is 1000 times as usual.

7. Make as few phone calls as possible, and don't chat on your mobile phone.

8. Headphones, especially Bluetooth headsets, can be used to keep radiation away from the brain.

9, careful choice of mobile phones, such as cdma mobile phones than g *** card mobile phone radiation is smaller.

Mobile phone radiation, the harm can not be underestimated. Cell phone radiation, everywhere, all the time. In addition to expecting advanced technology to eliminate radiation, we should also use mobile phones correctly to keep the radiation of mobile phones as far away from our bodies (especially our brains) as possible, thus effectively protecting our health.
