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.

After reading the above introduction about smart phones, I believe you have a certain understanding of smart phones.

I see. We should make full use of the advantages of mobile phones to facilitate our lives.

3. 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.

How to move the mobile phone?

With the development of science, people have invented many convenient things, including computers, telephones, public telephones and mobile phones. Nowadays, people use mobile phones the most, because it allows people to talk with others anywhere, unlike the telephone that can only be used at home. Mobile phones also have a nickname called "mobile phones". Many people call it a "mobile phone". Look, my mother also has a "mobile phone".

Mom's mobile phone is a Samsung brand mobile phone. Its appearance is small and exquisite, its color is silver gray, its shape is rectangular, its shape is slightly round, and there is a small screen above it to show the time. When you hold it in your hand, you can feel its exquisiteness and magnificence.

When you open it, there is a big screen flashing a faint light. Here are some keys, such as number subtraction, power-on key and power-off key-the appearance alone is enough for you to enjoy for a while.

This mobile phone has many functions, such as information, multimedia, entertainment, notepad, computer, pictures-my favorite function of information. It has a lot of ink in its belly, such as delete box, outbox and inbox. I remember one time, my pinyin level dropped sharply. If it weren't for this function, I really couldn't get my pinyin ability back! I also want to thank this "mobile phone"!

Mobile phones have brought us convenience. With the development of science, I believe that mobile phones will "go up a storey still higher"!

5. Write an 800-word composition, preferably an argumentative one, entitled "What has the mobile phone brought us". The urgent mobile phone has brought me convenience.

Nowadays, mobile phones have become an indispensable tool in modern life. Some people use it to work, some people use it to chat, and some people use it to send messages. ...

Our current mobile phone is really easy to use and convenient, and it can be contacted regardless of the ends of the earth, which is much more convenient than 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 tools. ...

However, what mobile phones bring 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 "picking chrysanthemums under the hedge", will his cell phone ring? 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. After talking on the phone for an hour, she can talk about the stars in the east and the singers in the west. She is like a "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. A girl refused to give up her seat to an old man on the bus. This behavior was photographed by a passenger with his mobile phone, and the photo spread on the Internet. This has aroused people's controversy. Some people criticize her, and some people think it doesn't matter. I think we should park for the elderly. After all, in the society of the elderly or vulnerable groups, we should not be like girls. We should respect the elderly and take the initiative to go to the elderly park at this time. .

7. What is the most popular way to write a 500-word explanatory article on a smart phone? Buy a smart phone, of course. What's special about it? It is estimated that most people will answer: fun! However, do you know its harm to people?

First of all, talk about its price. This kind of mobile phone is usually around seven or eight thousand yuan, but now the price has gone up, and some smart phones may be around ten thousand yuan. This price often poses a great threat to people who are not rich but want this kind of mobile phone, forcing them to "go bankrupt."

Let's talk about its harm to the family first. Because children nowadays are "overindulgent", there are many phenomena of "smashing fat". Some children will show off to their peers with a smart phone: "Look, I have such a fashionable mobile phone, how rich our family is, and you don't even have such a mobile phone, envy you, poor man!" Those children who listen are often envious on the surface, but they are not convinced psychologically. They will think: What's the big deal with having such a mobile phone? Look, I will bring a "luxury" mobile phone next time! Therefore, they will ask their parents to buy themselves a smart phone. Because of doting, parents will buy them such mobile phones, thus "losing everything" and becoming beggars.

Then talk about its harm to children. According to related reports, in recent years, children's myopia rate is increasing and their physique is declining. What's going on here? Smart phones, of course! Because children often like games on their mobile phones, they will play them when they do their homework and in class. Some children even hide their smartphones under the covers because they can't sleep. This, of course, led to the injury of children's eyes caused by the strong light of mobile phones, and also led to the failure of children to complete their homework because of playing mobile games, and their grades plummeted. Because playing mobile games for a long time, I seldom exercise, which leads to obesity. Running a few steps will make you angry, leading to physical decline and various diseases.

Finally, talk about its harm to human body. As we all know, electronic products have radiation, and mobile phones are no exception. Moreover, the radiation protection ability of children's skulls is not as strong as that of adults, and radiation naturally enters the brain easily. This leads to various intractable diseases such as memory loss and dementia. Friends, is this what you want?

Having said that, everyone knows the harm of smart phones, and it may not be so good. However, as long as we make good use of it and are not stubborn, its harm can also be lost by us. Nothing is perfect!

8. Write an article on mobile phone, with a narrative of at least 900 words. The phenomenon of using mobile phones can be seen everywhere in the streets, shops and parks. 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.

9. Write an explanatory article of about 600 words on the topic of 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.

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

10.& lt& gt The composition is 600 words urgent. Everyone will be surprised to see this topic! How can a mobile phone cause trouble? Alas! Listen to me slowly!

One day, I played games with my father. Usually my father seldom plays with me, so I must have a good time this time. When my father and I were playing again, suddenly, the phone rang. That's my father's cell phone. He immediately picked up the phone and pressed the answer key. "Yi Yi Ya" said. After a while, my father said to me, "It's raining. My father went out to do something. I'll play with you when I come back." I gave a reluctant "Oh". Dad immediately picked up his briefcase and ran out. 10 minutes passed, half an hour passed ... time passed by me, and gradually I fell asleep. I heard my father say, "It's raining. I'm sorry to have kept you waiting so long." Hum, dead mobile phone, broken mobile phone, if it weren't for you, dad wouldn't have left.

Once, my father's PHS was "retired", and under my tenacious beating, my father finally agreed to give it to me.

Yes I am ecstatic, either setting the bell or playing games; Either set a time or listen to music, but I'm so happy. I plan to wake me up with it every day, so I set the time. When I woke up the next day, my cell phone didn't ring. I thought I got up early, so I looked at the time. "ah! It's seven twenty-five! " . I let out a cry, dressed quickly and rushed out of the house without even eating a few mouthfuls of breakfast.

Alas, it's all the fault of the mobile phone!
