Please write a composition on the topic of mobile phone.

1. Write a composition on the topic of "mobile phone" and come to the mobile phone with materials. From this incident, I got a profound enlightenment: when we find other people's things, we must find ways to return them to their owners immediately, and don't be greedy and make the lost people anxious and depressed.

In order to facilitate contact, my father bought me a Nokia mobile phone. I was so happy that I grabbed my mobile phone and watched it happily.

I can't make a phone call when I see that my mobile phone is all in English. I can only play games, and there is an additional function. Dad smiled and said that the SIM card was not plugged in, so it was impossible to make a phone call.

Then help me insert the card neatly, and the English on my mobile phone will be converted into Chinese immediately, and the dial tone will be there. I checked my phone number first, and then clicked on the menu. There are so many functions now: information, communication records, address books, games and so on. Among them, the additional functions are fun, including self-entertainment, stopwatch, computer, unit conversion and so on. The most fun of these functions is self-music, and a song can be played by pressing a few keys.

Computers and unit conversion are also my helpers. Let's forget the game. Anyway, it's fun.

I can also demonstrate the operation method here. I learned it easily soon, and then my father adjusted the time of the mobile phone again, and a mobile phone was perfect. However, early this morning, I found that my mobile phone was missing. I looked in drawers and bookcases, but there was nothing.

I went to the bathroom and kitchen, but there was no sign of my cell phone. I dialed my number in a hurry, but my mobile phone was turned off, but my mobile phone was not turned off. I'm so bored that I'm not even in the mood for breakfast.

Mom and dad let me think about it. I sat on the sofa, trying to remember: Yesterday afternoon, we had dinner in "Old Backbone Castle". I used my cell phone and put it in my pocket.

Later, because the room was as hot as a big steamer, I took off my clothes and put them on the stool. I haven't paid attention to my mobile phone since I got home.

"It may have been lost in that hotel." Mother expressed her opinion.

When we went to the store to explain our purpose, the people in the store refused to admit that they had found it. We had no choice but to leave the hotel in frustration.

I went home at night and searched for it for a long time, but I still couldn't find it. Dad advised me: "Forget it, I'll get your number back, and I'll give you my old mobile phone."

Dad's words finally gave me some comfort. However, I am still using my home phone to keep dialing my mobile phone number, hoping that someone will suddenly connect and let me get my mobile phone back at once.

In fact, it is not good for primary school students to bring mobile phones. If they lose them, they will lose a lot. Now that there are many thieves, we should also guard against the theft of valuables around us. From this incident, I got a profound enlightenment: when we find other people's things, we must find ways to return them to their owners immediately, and don't be greedy and make the lost people anxious and depressed.

2. Write an 800-word composition on the topic of "mobile phone". 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. 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. ...

Smartphones are really amazing! 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. With the development of science and technology, we are more motivated to learn. 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.

3. 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?

Nowadays, mobile phones have become an indispensable tool in modern life. Some people use it to work, some people use it to chat, some people use it to send short messages ... Our current mobile phone is really easy to use and convenient, and it can be contacted no matter the ends of the earth, which is much more convenient than the previous letters.

It can be said that it is "a stone's throw away", and the world we live in is surrounded by cell phone signals. Its powerful function is beyond the reach of a tool ... but what the mobile phone brings us is not necessarily good, and sometimes it has disadvantages.

Mobile phones have changed many people's ideas, which can also be said to limit people. Imagine, when the poet Tao Yuanming is "under the hedge of picking chrysanthemums", will there be a cell phone ringing? When Li Bai lamented that "I sank back, and I suddenly remembered home", would someone ask him to visit his home? Certainly not! 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 the famous yakkers any more. Some people have mobile phones and never go to the post office again. Do you think there will be a scene of "Hongyan passing the book" now? Just make a phone call. At the full moon, will someone think about every word and how to write home? What's wrong with texting? During the Chinese New Year, sending a text message is a New Year greeting. If you carefully write down your blessing, put a stamp on it, pass the postman's hand and reach your friend, you are still full of body temperature! Every sentence is warm and happy, and your friends will be very happy.

What about the text message you sent? Every word is cold and heartless. The person who received it, that is, just take a look at it and delete it after replying.

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. It tastes delicious! My father is a lawyer. He is busy every day, like a never-ending top. He calls while eating, while watching TV, while reading, and even when he sleeps. If someone calls him, he often says, "My mobile phone is on all day. Call me if you need anything." How busy you are! I don't think it's possible for him not to touch his mobile phone for a day.

It's scary to think that when I grow up, I may stay in front of my mobile phone every day like my father, never leaving my feet! My cousin, a high school student, also has a mobile phone in her hand and is addicted to calling every day. It takes an hour to make a phone call, and she can chat with the stars in the East and the singers in the West, like "How the water of the Yellow River moves out of the sky"! To this end, her parents stopped using her mobile phone and "confiscated it". They said, "It's no good for high school students to chase mobile phones every day, which will affect their studies!" I feel very strange about this. Why do 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 use mobile phones reasonably, but we should not indulge in the world of mobile phones.

6. Ask middle school students the advantages and disadvantages of using mobile phones. When we walk into today's middle school campus, we will find that many middle school students have their own mobile phones.

In a sense, mobile phones have become an important part of their lives. To this end, we investigated some students and teachers in our school. According to them, there are about 10 students using mobile phones in each class, and some classes are even more.

According to a class of 60 students, about 16% of middle school students are using mobile phones. In the survey, we found that these students who use mobile phones are divided into fixed and temporary categories.

Fixed ones are bought by parents themselves, and students can control them freely. Temporary ones are given to children by parents when they don't use them for a certain period of time. Small counties are like this. What about big cities? According to the online data, a reporter distributed 500 questionnaires in two middle schools, and conducted a sampling survey on the use of mobile phones by middle school students. The survey results show that there are 258 students with mobile phones, accounting for 5 1.7% of the total number of the survey, among which high school students are the main ones.

In economically developed areas such as Beijing and Shanghai, its proportion has reached an alarming level. Even some foreign teachers from developed countries were surprised.

Should middle school students have mobile phones? The advantages and disadvantages of middle school students using mobile phones have aroused great concern from schools and parents. Parents: Parents who use mobile phones to "remotely control" their children's whereabouts and advocate buying mobile phones for their children all say that the first purpose of buying mobile phones is to find children at critical moments, such as urging children to go home as soon as possible after school.

Second, once the child Lu Yu is a bad person, you can call the police in time. Let's listen to the voices of several parents: a lady claimed that "the mobile phone is not expensive now, and it looks beautiful." It is very convenient to buy one for your child, so that you can't find anyone in a day. "

I just bought a mobile phone for 17-year-old son in the summer vacation. Another parent also said, "After the child has a mobile phone, we have more communication.

I used to feel that when my son grew up, there was a generation gap with my mother. Now, he will send us messages, chat and make jokes from time to time. The atmosphere at home is much better. "

The mobile phone is actually a "rope", which can "tie" children and reassure parents. It seems that parents have good intentions, but in real life, students with mobile phones have also brought endless troubles to their parents.

Mr. Liu also bought a mobile phone for his son who went to middle school this year. Who knows, whenever Mr. Liu needs to find his son immediately, his mobile phone is always "turned off" and he can't be contacted in any hurry. Now, his son still comes home late because his cell phone is dead or he forgot to turn it on. Anyway, he can have a hundred reasons to wait for you.

A parent also said that since he bought a mobile phone for his children, they don't need a home phone at all, and often hide from their parents and use their mobile phones to contact the outside world. Parents also admit that children use mobile phones to talk about learning, mainly by texting, playing games or surfing the Internet.

Some students interpret parents' kindness as: "My parents always call me and monitor my every move, which is particularly annoying." Student: If my classmates have it, I have to have it.

A student saw that many students in the class 10 had mobile phones, and he insisted on getting a mobile phone. The reason is that other parents buy mobile phones for their children, and the children clamor for them every day. Mobile phones cannot be "backward" like bicycles. According to the statistics of a class teacher, eight students in her class have bought new mobile phones since the school started on September 1.

Sometimes, as soon as we have a rest, we will see students "learning" their new mobile phones from each other. Mobile phone is a communication tool, but with it, the initiative to contact parents is in the hands of children. As for how and what to contact, it depends on their purpose.

I once witnessed such a scene: on a bus, I saw seven or eight middle school students in school uniforms chatting happily. One boy suggested "getting together" for dinner, and another boy immediately suggested contacting his parents. I saw him take out his mobile phone and dial the phone and say, "mom, I'm going to make up lessons at night." I'm going to review late and won't go home for dinner. "

After the phone call, he proudly said to his companion, "It's convenient to have a phone." I don't think this is an isolated phenomenon. Mobile phones facilitate their lies.

Teacher: SMS interferes with classroom teaching. Many schools have a firm attitude towards the advantages and disadvantages of students using mobile phones: mobile phones interfere with classes, and yellow text messages hurt children. According to reports, most students use mobile phones to play games and receive short messages, especially yellow short messages, which are obtained from the Internet or other channels.

The interference of mobile phones in the classroom affects the normal teaching, which makes many teachers very headache. A class teacher said that he often heard the sound of mobile phones in class. Although some students turned the mobile phone into mute, the short tone prompt function of the mobile phone still affected the class order. Some students are obsessed with texting in class, which makes teachers more headache.

He said that after the school started, the school organized several special inspections of students playing mobile phones in class and collected some mobile phones on the spot. Judging from the situation of receiving mobile phones, these students mainly send messages quietly in class, of which "yellow paragraphs" account for more than 70%. These contents are undoubtedly harmful to children's physical and mental health.

Students are willing to use mobile phones to send text messages because the "one-on-one" way is relatively hidden, and writing notes is easy for teachers to find and check. Some students are addicted to short messages, and their academic performance has dropped significantly. Finally, we made a summary of the above interview: as a new tool brought by scientific and technological progress, mobile phones have no advantages or disadvantages.

The negative effects of entering the campus, such as affecting study and showing off each other, only further exposed the weakness of students' public awareness. If it is just a simple ban, it can only be covered up on the surface, and it can't solve the problem fundamentally. The key lies in the school, and the most fundamental thing is to improve the moral education level of the school as a whole, so that students have a sense of self-discipline and use mobile phones with a healthy and civilized attitude.

As parents, blindly satisfying students' vanity psychology of blindly pursuing fashion and conniving at their use of mobile phones will cause students' comparison psychology, distinguish their identities by the grade of mobile phones, and cause psychological imbalance of some students, which is not conducive to cultivating students' good quality of diligence and thrift and excellent style of hard work and simplicity. Lang Lang's reading is mixed with one another. Can normal classroom order be guaranteed? Is it harmonious with the quiet campus learning atmosphere?
