My task:

Nowadays, youngsters have a massive explosion of interest in electronic games. While some parents believe that this situation have a debilitating effect on their offspring, others consider it a positive trend. This trend would introduce both pros and cons, but I am of the opinion that the drawbacks do outweigh the benefits. To begin with, playing computer games for a long period of time can have a negative effect on the overall well-being. Electronic games make teenagers have a sedentary lifestyle, which is the chief cause of cardiovascular disease. Besides, seeing the computer's screen also impair our vision and causes loss of memory because the radiation from computers is harmful to our brain and our eyes. Second, teenagers are easily addicted to video games, which results in a bad impact on their study's results. Despite these disadvantages, children can also reap great benefits in playing video games. The main advantage is that teenagers can reduce stress after hard work day, but we ought to play them rationally. In conclusion, it seems to me that video games do us more harm than good.
