The earliest mobile phones can talk wirelessly and are easy to carry. If you want to make a phone call, just press the button and you can talk to the other party. It has provided great help for you to communicate with the world. But as far as I know, only ten years ago, my mother was still using a mobile phone with a thickness of about 4 cm. Even the screen is less than half the size of my current mobile phone, and it is not a color screen. Only some basic functions, such as making phone calls and sending text messages.

Let's take a look at the current mobile phone. We can get a lot of fun from it, such as watching TV, chatting on QQ, playing games, listening to music and chatting online. Take my mobile phone, for example. My first mobile phone is a mobile phone worth more than 300 yuan. The screen of that mobile phone is not as big as my watch! Anyway, the mobile phone I use now is twice as big as the old one, and its functions are much richer than before, such as watching TV, taking photos, chatting on QQ, handwriting input method, playing games, recording videos, listening to music, chatting online and so on, which are all things that I didn't have in my old one.

The most important thing is the camera function in the mobile phone, which is convenient for us to use when traveling or going out. With it, we can photograph the beautiful scenery we meet. For example, at the seaside, others take out their mobile phones and digital cameras to take pictures of beautiful scenery. Not to be outdone, we immediately took out our mobile phones to take pictures.

With the wide application of mobile phone, it has become an increasingly indispensable part of people's daily life. The extensive functions of mobile phones make some people almost inseparable from them.

Mobile phone is the main invention of modern science and technology. If we look at our society, they are a happy part of our daily life. We can see that all kinds of people are using mobile phones. Maybe they have many advantages, but they also have shortcomings. The main advantage of mobile phone is that people can use it anytime and anywhere, so they can use it in an emergency. In addition, people can use their mobile phones to surf the Internet at any time, so business people can use their mobile phones to get information from the Internet more conveniently at work. Besides, it's easy to send messages to friends. Mobile phones can keep people close, even though they are far away. Mobile phones are turning the world into a village where we can communicate with each other easily and simply. Finally, another point of supporting mobile phones is that you can avoid disturbing anyone when he is sleeping or working, because in this case, people usually turn off their mobile phones. On the other hand, there are some shortcomings. First of all, the most important disadvantage is the unknown impact of excessive use on health. Scientists have found that cell phones can cause brain cancer. If you talk on the phone for a long time, you will have headaches and ear problems. Second, mobile phones stimulate the high communication costs of families. If you are a family of three, you will spend a lot of money on your mobile phone. Because there are two or three families, it takes about 150-200D a month. In addition, improper use of mobile phones may bring trouble. For example, in a formal conversation, class, library or cinema, cell phone ringing is very inappropriate. Finally, mobile phones waste too much time. An American survey shows that teenagers spend an average of two hours sending messages every day. In a word, mobile phones have advantages and disadvantages. Personally, I don't like mobile phones very much, but I need to use them. In my opinion, a mobile phone is good only when you use it correctly and politely, because in this case, all technologies are beneficial.

With the development of science, people have invented many convenient and quick things, including computers, telephones, public telephones and mobile phones-now people use mobile phones the most, because it allows people to talk with others anywhere, unlike telephones that can only be used at home. Many people call it a "mobile phone". My mother also has a "mobile phone", which is small and exquisite, silver-gray, rectangular and slightly round. There is a small screen on it that shows 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"!

These are the common features of most smart phones.

So what other functions do smartphones have? The word "smart phone" is mainly aimed at "feature phone", which itself does not mean how "smart" the phone is; From another perspective, the so-called "smart phone" is a "small computer" that can install and uninstall application software at will.

After sorting out and analyzing the survey data, I found that the functions of smart phones include: normal phone calls, text messages and other mobile phone applications; Can connect to the wireless network; Able to browse web pages and multimedia applications; Humanization, can expand the machine function according to personal needs; Open; Powerful, supported by third-party software.

For smart phones, it is not enough to know only the features and functions. We must be clear about the maintenance methods of smart phones.

First of all, we should pay attention to the storage method, keep the mobile phone away from the magnet environment, pay attention to the use environment and protect the shell.

Secondly, for the battery, we should grasp the charging time, choose the charger carefully, and don't charge it too frequently.

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

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

I opened my sleepy eyes and glanced at my watch absently. It's only half past three, and it's still early to get up. I fell asleep again ... I fell into a laboratory. Oh! What a big laboratory! Where is the doctor busy? I glanced at the calendar. In 2060! It's amazing! How did I get here? Forget it, let's see.

I saw a large group of people studying a mobile phone.

The doctor told me that the name of this mobile phone is "silly girl" and "silly girl!" Isn't this a magic mobile phone? I saw it on TV! It's a mobile phone that can travel through time and space. It has many functions, such as video communication, stealth function and function transfer ... it's great to see this mobile phone! After the doctors finished their research, they were looking for someone who could control the silly girl. All eyes turned to me. I'm a little surprised. I said, "I'm kidding, I can't do it." But everyone unanimously recommended me that I have this ability, and finally I agreed.

I actually have a magical mobile phone! I turned on my mobile phone, and the silly girl said, "Please enter the power-on password." I said, "I love you!" "The secret security input is correct, please enter the mode options, real-life mode and mobile phone mode" and "real-life mode, OK". When the mobile phone is turned on, suddenly the silly girl says "Call the police, there is a disaster on the second ring" and the function is transferred. I flew to the scene of the accident and three people were seriously injured. I quickly said, "medical function", but silly girl warned that "the operation could not be completed" I

From then on, people called me flying man. As long as there is danger, I will appear.

One day, the silly girl sent out again: "Call the police. Two adults robbed an old man of his money. Do you want to start the social order function?" "Yes!" I rushed to the scene, caught the two adults and handed them over to the police, who gave them corresponding punishment.

Silly girl and I are happier every day.

I don't know how long it took. One day, I suddenly thought of my mother. I miss them so much that I decided to take the silly girl home to have a look.

However, in the time tunnel, there is a dangerous situation that the silly girl lacks energy. "This service ends at 10, 9, 8, 7, 6, 5, 4, 3, 2, 1." Silly girl is reminding me that we are sinking fast. I was so anxious that I shouted, "Silly girl! Help me! " Get up. What time is it? Time for school! "alas! This is a dream! I think: when I grow up, I will learn from a silly girl and make contributions to the motherland.

Our first impression of introducing the 600-word smart phone composition to the elderly is that it was a sunny Saturday morning, and we were lecturing in the theater, and the teachers showed their talents. We can't underestimate their strength, but I'm sure our class will survive.

In the end, our class won a small game, which also led to the later games.

Other classes are not easily convinced, which challenges our class.

Challenge can make our class teacher bother to prepare for us. At this time, we also organized a "charge guerrilla" to wipe out a thousand troops on the battlefield of the challenge.

The first time I played with the second grade, although they were young, they were still tough.

At first, we always had a lot of trouble, either because of the time error or because someone forgot the lyrics. At the last minute, we finally narrowly beat each other.

Hey, I'm really lucky to get through this! In the second and fourth grade competitions, our level has been deadlocked and evenly matched. Finally, we challenged the "king battlefield" of the fifth grade finals together.

At that time, we were still in the third grade, giving full play to our strengths and showing our elegance.

When grading, our hearts beat like rabbits, and when we finally announced the first place in our class, we jumped with excitement.

Another time, the teacher wanted to talk about the lesson "The Taste of Love", and many teachers from other schools came to attend the class one after another, which really packed our classroom. Some teachers also copied our tutoring plan. With the previous experience, everyone was calm and extraordinary, the class went smoothly, and the teacher was particularly happy.

I didn't say it twice, but I experienced too many challenges. Tomorrow, there will be more difficulties waiting for us.

I miss the struggle in our class. The past is old wine. Let's work harder and move towards the sunrise tomorrow.

I miss the lecture in the theater, gallants three times, and the storms our class experienced. I want to challenge the difficulties in the future.

Introduce the word 100. As we all know, mobile phones play an important role in our daily life. But in my opinion, they have both advantages and disadvantages. First of all, mobile phones make it convenient for people to keep in touch no matter where they are. Especially when they have something important, mobile phones can help people avoid travelling long distances to know things for themselves. Secondly, we can send information by mobile phone with little money, and each short message only needs 0.0 1 yuan. Thirdly, we can also play games, take photos or listen to music on our mobile phones. However, mobile phones also have many disadvantages. We have to pay for the wrong number that does not belong to us. Radioactive substances may be harmful to our health. Sometimes, in public places or meetings, the bell may affect others. So we should be careful to turn off the mobile phone in some cases.
