Later, color-screen mobile phones appeared, with sticks attached. The screen of this kind of mobile phone is colorful and looks much brighter than before.

Indeed, there are advantages to such development, but the disadvantages cannot be ignored. "The greatest respect for a person is not to use your mobile phone when talking to him."

He has always regarded me as a friend, and of course I do too, but I never imagined that a report would turn my life from heaven to hell. One day, as usual, I was watching TV with my host. A report caught my and my host’s attention: “I believe everyone knows about the dangers of smoking, but if someone tells you, every year because of mobile phones Will you be surprised when more people die than from cigarettes? Recently, a British cancer researcher issued the most serious mobile phone warning to date: more people will die from using mobile phones than from smoking. !

6. "Mobile Phone Readme" 600 words

I am a mobile phone, a very common communication tool in modern society.

In everyone’s eyes, I am not only small in size, easy to carry, but also extremely versatile. In our mobile phone world, there are also “races”: sliders, candy bars, flips, and full touch screens.

The sliding cover is like a drawer, which can be pushed forward and pulled back. A candy bar and a full touch screen are somewhat similar, except that the former relies on buttons, while the latter can be clicked with a pen or hand.

Compared with the previous categories, the clamshell is quite special. It can be said that its body is the longest and consists of two parts. The upper part is the screen and the lower part is the keyboard. How about it? It’s a little surprising. In addition, our colors are also colorful, and the main colors are comparable to the rainbow in the sky.

With the development of the times, human beings have more and more needs, and our colors have become richer. Now let’s talk about my body.

Although I am not big, I have a lot of parts. From the outside to the inside, there is the metal body first, followed by the important parts: the screen and keyboard.

When you open the back cover, you can see a square battery. This is my energy source, equivalent to your human stomach. When you take off the battery, you can see the memory card, which is my brain.

Next to it is the SIM card. Haha, it is equivalent to a bank card. All expenditures depend on it. Well, that’s roughly what I’m made of.

After talking about the body, it’s time to talk about the functions I’m proud of. I divide them into two categories: one is communication function, and the other is entertainment function.

Let’s talk about communication first. Communication includes making and receiving phone calls and sending and receiving messages. Comparing the two, making and receiving calls is naturally simple and convenient, and the expression effect is slightly better than the latter.

In ancient times, people communicating over long distances relied on writing letters, which took too long, was laborious, and wasted paper. Sending messages greatly improves efficiency, saves time, and is very convenient.

In fact, what attracts people’s attention more is my entertainment function. Some small games and music can effectively reduce the stress caused by modern fast-paced life.

Not only that, I also integrated camera, DV, audio recorder and other functions into one. Calculator and alarm clock are my basic tools.

The most special thing is e-books, which are easier to carry than ordinary books. With just one click, your favorite content will come into view. I also have another important function, which is the indispensable network application.

It can not only chat online and search for information, but also download songs and make videos... In short, I am a treasure chest of human life. Okay, let’s stop here. How about it? Do you understand me? I hope you will like me more and more, and I hope our development can provide you with more convenience and fun. 7.

From this incident, I got a profound inspiration: when we pick up other people’s things, we must find a way to return them to their original owners immediately. , Don't be greedy and make the person who lost the property anxious and depressed.

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

I saw that everything on the phone was in English, and I couldn’t make calls. I could only play games, and there was an additional function. Dad smiled and said that there was no way to make calls since the SIM card was not inserted.

Then he quickly inserted the card for me, and the English on the phone was immediately converted to Chinese, and the dial tone was also available. I checked my phone number first, and then clicked on the menu. There are now a dazzling number of functions: messages, communication records, address books, games, etc. The additional functions are fun, including self-composed ***, stopwatch, Computers, unit conversion, etc. The most interesting of these functions is the self-composed ***, where you can play a song with just a few clicks of a button.

Computers and unit conversion are also my helpers. I won’t mention the game, but it’s fun anyway.

The operation method can also be demonstrated here, and I quickly learned it easily. Then my father adjusted the time of the mobile phone correctly, and the mobile phone became perfect. However, early this morning, I found that my phone was missing. I went through the drawers and bookcases, but there was nothing there.

I went to the bathroom and kitchen, but there was no sign of my cell phone. I was anxious and hurriedly called my number. Unexpectedly, my cell phone was turned off, but my cell phone was not turned off. Now I am so bored that I am not even in the mood to have breakfast.

Mom and Dad asked me to think about it carefully. I sat on the sofa and tried to remember: Yesterday afternoon, we had dinner at the "Laohuitou Bone Castle". At that time, I used my mobile phone and kept 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 didn’t pay attention to my phone after I got home.

"It might have been thrown into that restaurant." Mom expressed her opinion.

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

When I got home in the evening, I searched for it at home for a long time, but still couldn't find it. My father advised me: "Forget it, I will help you get your number back when the time comes, and I will give you my old mobile phone to use."

My father's words finally gave me some comfort. However, I kept calling my cell phone number from my home phone, hoping that someone would suddenly turn on the phone and tell me to get it right away.

In fact, it is not good for primary school students to bring mobile phones. If they lose them, they will suffer big losses. There are many thieves nowadays, and we must also be careful about the valuables around us being stolen. From this incident, I got a profound inspiration: when we pick up something from others, we must find a way to return it to the original owner immediately, and don't be greedy and make the person who lost the property anxious and depressed.
