s="" use="" of="" computers="" show="" that="" there="" are="" possible="" negative="" effects.="" this="" essay="" will="" explain="" the="" effects="" computer="" on="" children,="" focusing="" family="" and="" peer="" relationships="" increased="" tendency="" towards="" violent="" behavior.Computer use may negatively affect the social relationship between children and their parents. Because children spend so much time on computers, they often know more about advanced computer use than their parents. According to Subrahmanyam and his colleagues (2001) this often leads to a role reversal, where the child becomes a teacher to the parent. In other words, it is often the case that a highly computer literate teenager will teach their parents how to use the more complex functions of computer technology. This can lead to a reduction in parental authority. Moreover, with the anonymity of online communication ,computer users do not know if they are talking to a child or an adult, so all users are treated equally (Subrahmanyam et al, 2001). Children may then expect the same equality in real life, further contributing to a breakdown in the parent-children relationship (Subrahmanyam et al, 2001).Children’s peer relationships can also be negatively affected by extensive computer use. Since computers are more likely to be used in isolation by children, they spend little time interacting with their peers (Shields & Behrman, 2001). As a result, children may not develop the social skills they need, or be able to maintain friendships in the real world ( Subrahmanyam et al, 2001). With the very extended computer use, this isolation from the real world can lead to loneliness and even depression (Shields & Behrman, 2001).A disturbing possible effect of computer use on children is the link between computer games and violence. Current research has already documented a strong link between violent films and television and aggressive behavior in children, so it is reasonable to believe that a similar link will be found between violent behavior in children and violence in computer games (Subrahmanyam et al, 2001). However, as Shields Behrman (2001) points out, it is important to note that although the games may affect all children, children who prefer violent games could be most affected.In conclusion, using a computer, particularly for extended periods, may affect the parent-children relationship in families. It could also result in children not learning the social skills they need to interact with peers and maintain friendships. Moreover, it seems likely that playing violent computer games is linked to violence in children. Although the research is not conclusive, it appears that extended use of computers could have a negative effect on children’s social development.1.From the very beginning, the author is trying to draw out attention to ( ).2.Which is the best reason for the reduction of parental authority according to the passage?3.What does Shield Behrman imply in the passage?4.Which of the following is NOT mentioned as the negative result of playing computer games in the passage?5.Where the passage might be taken from?'>

Children are spending an increasing amount of time using computers. Computers are now found in most classrooms, and in the majority of homes, almost always with internet access. However, many studies of children's use of computers show that there are possible negative effects. This essay will explain the possible negative effects of computer use on children, focusing on the effects on family and peer relationships and the increased tendency towards violent behavior.Computer use may negatively affect the social relationship between children and their parents. Because children spend so much time on computers, they often know more about advanced computer use than their parents. According to Subrahmanyam and his colleagues (2001) this often leads to a role reversal, where the child becomes a teacher to the parent.

That shabby unknown bundle of neglect and despair that was dropped off by the police six weeks ago—later to be identified by his mother, who turns up occasionally—is now a driving force on the infants’ ward. Once he was bathed a few times and his rashes were treated, he turned out to be a 14-month-old boy named Vergil, still recovering from premature birth——birth weight, 2.5 pounds, it came obvious he had never received any real attention, and practical no solid food, and it was never very clear who assumed responsibility for him in his family, if anyone. Miraculously he survived, with almost no outside help.At first he just lay there, withdrawn, sucking on an empty bottle as he had been used to doing at home. After a few days it became clear he was ravenously hungry and he downed bottle after bottle of milk. Slowly he began to respond to the ward staff around him who hung over the side of his crib, tempting him back to life.He started by cautiously chewing on people, sniffing and tasting them warily like a little wild creature. Gradually he climbed to a standing position, pulling himself up on the bars of his crib. Then he began to discover noise——that came from himself. When he learned that it was acceptable, in this place, to scream when enraged, he filled his corner of the room with garbled speech-like sounds, and loud baby-bellows of demand. If nobody responded he would fix each passerby with a coy look that evolved into a seductive grin, revealing four widely space little teeth. Someone always stopped, grinning back at this adorable creature, then picking him up and cuddling him. We on the staff took personal pride and delight in his steady progress.During the day we moved his crib from the infants' ward to the playroom where there are people coming and going. He loved it, standing and cruising in his crib, commenting happily on the scene, crowing and babbling. One afternoon, when his crib was moved adjacent to the wall, he became unusually quiet, deep in concentration. With the stealth of a cat, using his little fingers like tiny screwdrivers, he had taken apart the wall oxygen unit. Our delight in his progress turned to real respect. Perhaps we could steer him toward the right path before it was too late.Vergil definitely had a future.1.In the infants’ ward, Vergil ( ).2.The ward staff must have been marveled at Vergil's( ).3.How did Vergil begin to respond to people?4.
