The mobile phone that everyone is using now is called a smart phone.

then what is a "smart phone"? It refers to a kind of 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 can access wireless networks through mobile communication networks. In fact, I think the smart phone evolved from the PDA, which is the scientific combination and sublimation of the traditional mobile phone and personal computer, but it has obvious advantages compared with the traditional mobile phone.

Smartphones have brought us a lot of convenience. It can shop online like a computer.

I remember last year, our teacher asked us to buy a book, but my father went to several bookstores nearby and found nothing. We had to drive half an hour to the Xinhua Bookstore in the west of the city to buy it, and it took a whole afternoon to go back and forth. This year, my mother installed Alipay on her smartphone, and clicked on Taobao a few times. Many book exhibitions appeared in front of us, and the price was also discounted! I got several brand-new books the next day without leaving home, which is really convenient and affordable! Besides shopping, mobile phones can also show us the way.

This summer, 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 specific location, only know that it is near the intersection of Tianmushan College. After we got off at the intersection of Xueyuan by bus, there was no sign of the swimming pool, and we walked along Xueyuan Road for more than ten minutes. 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 we were getting farther and farther away. In fact, it was quite close to the place where we got off, thanks to this smart phone, otherwise we really became "poles apart".

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, we can only communicate through letters, which are slow and lack of color, because the letters only have black handwriting. This year, I learned her QQ number, and used my mother's smart phone to video chat online. We finally saw each other's voices and smiles.

After that, we often talk about learning and interesting things in our class through our smartphones in our spare time. They are often "moved" by each other, holding their stomachs and laughing incessantly. 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 won the award, my mother and I were on our way, and my mother had good news from her on her smartphone.

we'll have a video soon, and we'll show it to me in an orderly way. Although we are hundreds of miles apart, we shared the joy of success together at the first moment.

of course, the development of smart phones will be broader in the future. Not only personal communication, information management, schedule keeping, task arrangement, multimedia application, web browsing, etc., such as: stocks, news, weather, transportation, commodities, application downloading, music picture downloading, etc.

it will also be an important means of "smart city" and "smart family". To achieve wireless synchronization, it can release all the functions of smart phones, 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 a pleasure to think that household chores, such as washing and cooking, are all handled by mobile phones! According to my father, smart phones have been used in the military field in various countries. For example, the functions of taking photos, positioning and tracking, inertial sensing, Bluetooth signal, electronic compass, etc. of smart phones can be used for wireless remote control, that is, through the wireless signals of smart phones, micro drones and robots launched by themselves can be remotely controlled, and other drones and robots can also be taken over to complete reconnaissance and monitoring tasks and watch the video images shot by drones on the display screen in real time.

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

2. Write an essay about reading mobile phones

Modern devices will have many modern tools.

Electronic tools such as telephone, mobile phone E69DA5E6BA9162616964757A 686964616F31333331376566, TV and computer are becoming more and more popular, which is more and more convenient for people's lives. With the telephone, we can talk to anyone; With a mobile phone, we can put it in our pocket and communicate with others anytime and anywhere, regardless of time, place and other factors. With TV, we can sit at home and travel around the world; With the computer, it is even more important to answer our questions.

but today I decided to focus on the advantages and disadvantages of mobile phones and mobile phones. Mobile phones began to be used in about eight years, but they were only used by wealthy families and people with special needs in some big cities.

in the past nine years, mobile phones began to be universal, heavy and popular, not just limited to individual people. Young people, middle-aged people and the elderly can have their own mobile phones, and even mobile phones have a certain low position among some students and are favored by some students.

With the development of time and the progress of society, the functions of mobile phones have become more and more extensive. At first, it can only be used for talking on the phone and sending text messages. Gradually, we can listen to music and play games on our mobile phones.

Nowadays, besides those simple functions, mobile phones have added modern elements. Besides watching TV, they can also surf the Internet, access QQ and have video conversations with others. This shows the status and needs of mobile phones in people's daily life.

Walking on the street, you will see many people using mobile phones. With mobile phones, no matter how far or near, communication between the mainland and overseas is unimpeded; It is more and more convenient to talk with mobile phones, and the world is getting smaller and smaller; With a mobile phone, others can find you and talk to you wherever you are; With a mobile phone, you don't have to sit at home and wait for other people's calls, so you can communicate outside. Mobile phones make our contact easier, and our communication needs are met with higher standards.

surfing the internet with mobile phones has also met the real needs of many people. With the progress of the times, the modern functions of mobile phones have brought many benefits to people. Although mobile phones have so many advantages, their disadvantages must exist.

Some students use mobile phones too early, which leads to many disadvantages. Benefits: Playing games in mobile phones for a long time will make our eyes tired from lack of rest, and even it will be the culprit of our vision decline. Playing games in mobile phones for a long time is more likely to make us forget our study, which will lead to our study decline. E-books in mobile phones will make us mature prematurely, which is not conducive to our physical and mental development and even to our healthy growth.

If so, the mobile phone will not bring convenience to our life, but will bring resistance to the growth of more people. How can we turn the disadvantages of mobile phones into advantages? I think it depends on people's binding force.

If we manage ourselves reasonably by using mobile phones, instead of being slaves to games, we will become the owners of mobile phones, which mobile phone will definitely bring us endless benefits.

Nowadays, the mobile phone has become an indispensable tool in modern life. Some people use it for work, some people use it for chatting, and some people use it to send short messages ...

Our current mobile phone is really useful and convenient. No matter the ends of the earth, it can be contacted, which is much more convenient than previous letters. It can be said that it is "a short distance away", and the world we live in is surrounded by mobile phone signals. Its powerful function is beyond the reach of a tool at all ...

However, what the mobile phone brings to us is not necessarily good, and sometimes it has disadvantages. Mobile phones have changed many people's ideas, which can also be said to restrict people.

Imagine that when the poet Tao Yuanming was "picking chrysanthemums under the east fence", would there be a cell phone ringing? When Li Bai laments "sinking back again, I thought suddenly of home", will someone call him to visit his home? There must be no! However, they have many classic poems, but now we live in the era of Han Han and Jing M.Guo, and no one appreciates the excellent poems of those famous yakkers anymore.

Some people have mobile phones, and they have never been to the post office again. Do you think there will be a scene of "Hongyan passing books" now? Just make a phone call and it will be OK. At the time of the full moon, will someone think about every word and think about how to write a letter from home? Isn't it good to send a text message? During the Chinese New Year, sending a short message is a New Year greeting. If you write your blessing seriously, put a stamp on it, pass the postman's hand and reach your friend, and you are still full of body temperature! Every word is warm and happy, and your friends will be very happy. And what about the text message you sent? Every word is cold and emotionless. The person who received it, that is, just glance at it casually, reply to it and delete it. My friend once wrote me a letter. When I received it, I was so happy that I went to buy stamps, stationery and envelopes, sat in a chair, picked up a pen and prepared to write a reply. What a taste!

My father is a lawyer. He is very busy every day, like a top that never stops. He makes phone calls during meals, while watching TV, while reading a book, and even when he is woken up, he often says, "My mobile phone is on all day, so call me if you need anything." How busy you are! I don't think it's possible for him to touch his cell phone for a day. It's horrible to think that when I grow up, I may stay in front of my mobile phone every day like my father and never leave!

My cousin, a high school student, also has a mobile phone in her hand. Every day, she has a phone addiction. It takes an hour to talk on the phone, and she can talk to the stars in the east and talk about the singers in the west, which is like the spirit of "how the Yellow River's waters move out of heaven"! To this end, her parents stopped using her mobile phone, "confiscated it", they said, "It's no good for high school students to catch up with their mobile phones every day, which will affect their study!"

I wonder why so many people like to play and use mobile phones. Although the mobile phone is a modern high-tech product, why is it so attractive? I haven't figured it out yet.

It seems that mobile phones have both advantages and disadvantages. We should make proper use of mobile phones instead of indulging in the world of mobile phones.
