Smart phones provide users with a large enough screen size and support for 4G high-speed network access, which is not only convenient to carry around, but also provides basic hardware performance support for software operation and content services. At present, the smart phone system can support the operation of many third-party software, further expanding the scope of use of smart phones, which are the same characteristics of most smart phones at present; So what other functions do smartphones have?

The mobile phone system is independent of the mobile phone hardware, and can be updated by updating and OTA upgrading.

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

4. What is the most popular way to write a 500-word expository essay on the topic of 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 "overindulged by E799Be5Bae6E58685E5EB9313339653638", there are many phenomena of "getting 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.

6. Write a composition with the phone number, modern number and modern number as the topic.

Fixed telephone is very convenient. Today, national life, national life, national life and telephone.

それととにろなもてきたまずがぃ𞇅.

Scientists are highly likely to get sick or carry telephones. With the development of science, people have invented many convenient and quick things, such as computers, telephones, public telephones and mobile phones. 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"! ばされてぃるとそのはたちが See らればば.

さらにほをぅのはなもぁる, inappropriate place. For example, ぇばのでみんなんだり, Ben をんだり.

そのぁるはほをかってきなをしてて. I should think about it.

ぃろぃろなにしてほをやよぅとぃほ𞓘

On the road of human science, on the road, on the road, at the same time, on the road.

7. Write an explanatory article of about 600 words on the topic "The mobile phone is really smart", introducing that the mobile phone you know everyone is using now is called a 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!

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, make a mobile phone a time management tool, a mobile platform for work, and remotely control the TV at home. Such as taking photos, positioning and tracking, inertial sensing, Bluetooth signal, electronic compass and other functions. You can use the wireless remote control of smart phones, that is, you can remotely control your own micro drones and robots through the wireless signals of smart phones, and you can also take over other drones and robots to complete reconnaissance and monitoring tasks and watch the video images taken by drones on the display screen in real time. Of course, we still need to find out for ourselves.
