Advantages and Disadvantages of Mobile Phone Hello, Advantages and Disadvantages of Mobile Phone With the development of the times, a convenient and fast communication tool-mobile phone has entered thousands of households, and people can see the scene of a mobile phone in the street. There are many middle school students. With the increasing popularity of mobile phones, mobile phones have also entered the campus that is closely related to us. In each class, there are not a few students with mobile phones. According to the results of our questionnaire survey,

Middle school students should pay more attention to using mobile phones.

Middle school students use mobile phones at school. For example, if they find that they have forgotten their homework, they should call home after class and ask their parents to send it.

Of course, some students brought their mobile phones into the classroom, set them to vibrate and secretly played under the table.

Some send text messages on their mobile phones after lights out in the dormitory.

Middle school students' mobile phones are used to send and receive short messages, play games and surf the Internet.

More than 70% middle school students no longer use mobile phones as a tool to communicate with people, but a "mini" computer, which can send and receive information, play games, surf the Internet, listen to music and send pictures like a computer. Compared with the laptop on the desk, the mobile phone certainly has many advantages.

Some students feel that contact is convenient, easy to use and very light. No matter whether middle school students own or use mobile phones, it can be said that using mobile phone email news has become the main purpose of mobile phones. Even the students who make phone calls mainly chat and ask homework, and seldom contact their parents.

With the mobile phone entering the classroom, it will inevitably bring some disadvantages. Many students are addicted to short messages, sending all kinds of short messages to each other, and even whispering to each other to exchange interesting information they receive. They didn't study hard, which seriously affected the students around them. Bringing a mobile phone into the classroom will affect the normal classroom order. Some students even brought their mobile phones into the examination room and cheated by SMS. Several such cheating incidents can be found in every midterm and final exam, and mobile phones are used.

Some students who live in the dormitory play games, surf the Internet, listen to music and send text messages late into the night, which leads to lack of sleep, poor spirits the next day and greatly reduces their learning efficiency, which not only affects themselves, but also interferes with others' rest.

Based on the current situation of students using mobile phones, we have drawn the following advantages and disadvantages.

Advantages: 1 As a high-tech product, mobile phone can really bring a lot of convenience to our life. Students can contact their parents in time through their mobile phones, or they can report their study to their teachers.

2. communicate with former classmates more, which can maintain the original friendship, and communicate with current classmates more, which can enhance friendship. You can use your mobile phone to discuss problems.

The shooting function of some mobile phones can take some meaningful and valuable things at any time.

The alarm clock in the mobile phone can be used at any time.

The mobile phone itself is small and exquisite, covering a small area and can be carried around.

6. Students can ask their parents, teachers or police for help in time when they go out to play or encounter danger in other places.

Disadvantages: 1 Sending text messages to chat affects rest and delays study. Most parents report that their children use their mobile phones to chat and study less, and use their mobile phones to communicate with their classmates or send text messages more. Mobile phones have a great negative impact on their studies.

2. Bad information defiles the mind.

3. Encourage students to keep up with the joneses. Every time after school, students will get together to "learn from each other" about the styles and functions of mobile phones. There are more and more mobile phones on campus, and their grades are getting higher and higher. For those students who don't have mobile phones, it is easy to cause psychological imbalance. Under the influence of comparison psychology, some students began to chase blindly, because mobile phones are updated very quickly.

Appearance and function are changing with each passing day.

Students with brand-name mobile phones will show off their hometown and parents' status, which will make students regard their parents as their backers and not make progress.

4. Add extra burden to parents. The survey results show that all the money for students to buy mobile phones comes from their parents, and the monthly phone bill is also paid by their parents. For families with poor families, buying a mobile phone for their children is equivalent to adding a new burden to the family.

Mobile phones provide conditions for cheating in exams and form an unhealthy style of study.

6. Affecting campus security, mobile phones are valuables, and theft often occurs. In addition, the adverse effects brought by mobile phones are more prominent, which leads to crimes committed by middle school students, and middle school students with mobile phones have also become the targets of some criminals to cheat and rob.

7. Middle school students' use of mobile phones will hinder the teaching order of the school. Some students don't turn off their cell phones in class, and sudden calls will affect all students' attendance and bring unpleasant emotions to the whole classroom.

8. Mobile phones are radioactive to people. Many advertisements only say how many advanced functions the mobile phone has, and never mention the harm to the human body.

Teenagers are in the golden stage of growth and development. If they are harmed by mobile phones, they will not regret it.

As a new tool brought by scientific and technological progress, mobile phone is a new thing, which conforms to the law of social development and the fundamental interests of the people, and there is no right or wrong in itself.

The negative influence after entering the campus further exposes the "old problems" of school moral education such as students' weak sense of rules.

Banning school paper can only cover up the superficial problems, and middle school students should be divided into two if they have mobile phones.

Nowadays, middle school students in the information age are no longer nerds who "don't listen to things outside the window, just read idle books".

Therefore, owning a mobile phone as one of the main communication tools in modern society is inevitable for social development and progress. With the improvement of living standards, it is not too much burden for many parents to equip students with a mobile phone. With mobile phones, parents can better supervise their children.

Of course, we can't ignore the new problems brought by mobile phones entering the campus. The most fundamental thing to achieve "for-profit" is to improve the overall moral education level of the school, so that students have a sense of self-discipline and use mobile phones with a healthy attitude.

In the information age, mobile phone has become the main information contact tool.

For students, mobile phones can be used as watches, and functional mobile phones can be used as learning machines, microcomputers and cameras, which reduces expenses. They can also be used to surf the Internet, learn and inquire about all kinds of knowledge. They can also be used as dictionaries, dictionaries and good assistants for learning Chinese and English. ...

However, mobile phones can also bring problems to people. The most serious is radio wave radiation, which is considered harmful to the user's brain. Another problem is that when people are in a meeting, having a class or listening to a concert, cell phone ringtones may disturb others. So I think children should use their mobile phones as little as possible, and they should turn off their mobile phones when they attend important meetings or classes. (2) Mobile phones have many advantages. First of all, it is much more convenient than ordinary telephone. No matter where you are, you can call. If you are sick or see an accident, you need an ambulance to arrive at once. Cell phones can save your life. Secondly, texting is much cheaper than calling.

They can chat with several people at the same time through their mobile phones, but they can't perform well in face-to-face meetings. Some students abuse mobile phones. They use them to play games, which is not good for their eyes and will waste a lot of time. Obviously, carrying will interfere with classroom teaching and lead to students' prejudice.
