Let's take a look at the computer, not to mention the wide-screen LCD monitor, the intelligent photoelectric mouse and the compact new chassis. Even the small noise (sound) is a bit like it. Everyone in the family loves computers.
But when we are happy, the troubles brought by computers are also uninterrupted.
One day, I had a lot of homework and it took me a long time to finish it. I saw my father sitting in front of the computer and said to him, "Dad, check my homework." Dad said helplessly, "I see." Then he came lazily to check his homework. While dad was checking his homework, I quietly went to the computer to check the information I wanted to know. Who wants to sit still, my father said to me, "You have finished your homework." When I went back, my father just glanced at it and didn't even recognize right or wrong. I fell in love with the computer psychologically, which made my father's homework check not serious.
Sometimes, our family is not "happy". My father will use the computer to write reports, my mother will use the computer to make reports, and I will use the computer to find study materials. Everyone needs to use it, and our family will do its best.
This is my family's computer, which can bring convenience to our family's life and study, but also bring countless troubles!
2. The composition of computer hazards Now technology is more and more developed, from the initial position to
Later, the telegram arrived at today's telephone and mobile phone, and now
Now computers have been invented. Computers have many uses, when
However, these uses are both good and bad. First, we can board the plane.
Record QQ, chat with friends online,
As long as you click the mouse, the message you send is very different from the other party.
It will be received soon. We can also send emails online.
Not only that, with the internet, we can know without leaving home.
Know what is happening in the world. On the Internet, we are light.
You can order your favorite goods conveniently and quickly.
This is the advantage of computers. Let many people work for computers.
The culprit is computer games, Xu.
In order to play computer games, many students' studies plummeted.
Parents can't stop, and some even take risks.
Taking the road of crime is even more serious on the spot.
Death eventually leads to the destruction of the family. Computers are a pair.
Sword, it can make you learn well, and it can also make you learn badly.
I hope you can control yourself.
On the advantages and disadvantages of computers On the advantages and disadvantages of surfing the Internet, all technologies are double-edged swords, and the Internet is no exception.
Inter originated from ARPA, the predecessor of the Advanced Research Projects Agency of the US Department of Defense. The network was put into use on 1969. At first, it was only used in the military. Later, through the improvement of Joseph, the father of the Internet, the Internet constantly entered our lives, making our lives rich and colorful.
Internet makes information browsing faster and more convenient. If it's at 1990, we should look up all kinds of information about America, go to the library or make long-distance calls to ask our relatives and friends in America.
It's different now. With the internet, you can find all kinds of information about "America" with a click of the mouse, and it doesn't take ten seconds. Internet makes the communication between people closer and faster.
In ancient times, if you lived in Dongguan and wanted to write to your relatives and friends in Beijing, you had to send the letter by horse, and the time ranged from one month to one year. Modern can make long-distance calls, but it is very expensive, and you can't send documents or pictures; Now with Inter, we can communicate with friends and relatives in distant places and contact American customers through QQ and E-mail. It only takes about 1 yuan to talk for an hour, and you can also use videophone, so the distance between people is getting closer and closer. However, the Internet also has many shortcomings. It has become the best weapon for criminals.
Criminals use the internet, a virtual and vast world, to carry out criminal activities. They wear the protective clothing of the internet, so that people can't see their ugly hearts.
Newspapers often report that "a woman in XX was cheated to death because of QQ", which is an ironclad fact. In addition, there are many "hackers" who spread viruses everywhere, greatly reducing the speed of the Internet and seriously blocking the Internet highway.
To make matters worse, some illegal websites actually provide pornographic, violent and other pictures and words on the Internet, which seriously poisons people's minds. In today's society, the Internet provides us with an infinitely vast land. Dear netizens who grew up in this land, don't let this land be abandoned, use it to cultivate rich fruits.
4. Composition: About the advantages and disadvantages of computers today, we had a unique discussion class entitled
Advantages and disadvantages of computers. When the teacher wrote the topic on the blackboard, the students cheered and were eager to try. It seems that students have a lot to say!
First of all, Zhang stood up and said, "With a computer, you can know the anecdotes all over the world. I know from the computer that there is a smallest country in the world, and you can kick football out of the country with one foot. " Some people say that it can also help teachers make courseware, help us learn the order of strokes and draw pictures. For example, if the stroke order of the word "smoked" is not good, turning on the computer will teach me to write. Zhang Fan Ying said: "We can also use computers to collect the information we need, consult the knowledge we don't know and make our own cartoons, so that I can enjoy unlimited happiness." ..... The students scrambled to speak.
When the students were in full swing, Xiaohong got up and said loudly, "Please pay attention to the students. Although the computer is good, it still has shortcomings! At this time, I thought to myself, the computer is so good, how can it be harmful? I don't know. Then the teacher said, "Xiaohong, you reminded me very well!" "Classmates, computers have both advantages and disadvantages. We shouldn't watch computers or play online games for a long time, otherwise we will be nearsighted and addicted. "
Just then, Wang Xiwei replied, "We shouldn't be obsessed with computers for a long time. If we are addicted to computers, our study will decline and even break the law. I saw in the TV newspaper that a person killed someone in an Internet cafe because he was addicted to online games, which broke the law. "
The end of a heated discussion class not only made me know more about computers, but also made me understand that computers should serve us, not be our masters.

6. Write a composition. The disadvantages of primary school students playing computer are not less than 250 words. First of all, playing computer games takes time. If we play computer games too much, the time we spend studying will be greatly reduced, unless we are geniuses who can study without studying. As far as we ordinary people are concerned, it is strange that our academic performance will not decline! Secondly, playing computer games, especially for a long time, is very harmful to our eyesight and health. When you indulge in the pleasure brought by computer games, your eyesight will decline day by day unconsciously. When you finally wake up, it's too late! Maybe I can find the healthy body I once had.
Third, playing computer games is especially a waste of money. As primary school students, our pocket money mainly depends on parents' gifts. Imagine, whose parents are willing to give us money to play games online very readily? Therefore, in order to play computer games online in Internet cafes, we are bound to ask our parents for it under various excuses, otherwise we will try our best to make money, and there is no mind to study at all, and some students even go to the point of no return. Why bother? There are many dangers of computer games, so I won't list them one by one. Some people may not be convinced. You have said so much about the dangers of computer games. Is the computer game not good? At least playing computer games can exercise our body, improve our reaction ability and the rapid coordination ability of our hands and brains, help us understand computers, know computers and learn computers, and let us relax in the intense study. There are still many benefits! Besides, aren't there many adults who are addicted to computer games? Playing computer games may have some advantages in one way or another, but when the advantages and disadvantages are weighed together, I think the disadvantages of playing computer games far outweigh the advantages, so I still firmly believe that for our own future, students, please stay away from computer games.
