The 21 century has brought with it a variety of recreational activities.Reading is a welcome leisure activities though an extrovert is more possibly to prefer outdoor sports.Apart from that,one could spend free time shopping,watching a film and so on.There are still plenty of alternatives else,ranging from Karaoke or dancing to all kinds of online ones. However,recreational activities may be beneficial,or,quite the opposite,be harmful.We can broaden our horizons by the activities such as reading books,but then,some activities may seriously affect one’s normal life if he is addicted to it.For example,people getting into the habit of playing computer games will indulge in illusions and have a disability in social contact with the passage of time. As a college student,I think we should treat the subject fairly.Recreational activities have no fault.On the contrary,it is the addicted people who are to blame.The conclusion is clear that we can profit a lot by recreational activities so long as we make a proper arrangement .
