(C)-|||-Each summer,no matter how pressing my work schedule,I take off one day exclusively-|||-for my son.We call it dad-son day.This year our third stop was the amusement park,where he-|||-discovered that he was tall enough to ride one of the fastest roller coasters in the world. We-|||-blasted through face stretching turns and loops for ninety seconds. Then,as we stepped off the-|||-ride,he shrugged and,in a distressingly calm voice,remarked that it was not as exciting as-|||-other rides he`d been on.As I listened,I began to sense something seriously out of balance.-|||-Throughout the season,I noticed similar events all around me.Parents seemed hard pressed-|||-to find new thrills for indifferent kids.Surrounded by ever-greater stimulation,their young faces-|||-were looking disappointed and bored.-|||-Facing their children`s complaints of "nothing to do",parents were spending large numbers-|||-of dollars for various forms of entertainment.In many cases the money seemed to do little more-|||-than buy transient(短暂的)relief from the terrible moans of their bored children. This set me-|||-thinking the obvious question:"How can it be so hard for kids to find something to do when-|||-there`s never been such a range of stimulating entertainm available to them?"-|||-Why do children immersed in this much excitement seems starved for more?That was,I-|||-realized,the point. I discovered during my own reckless adolescence that what creates-|||-excitement is not going fast,but going faster. Thrills have less to do with speed than changes-|||-in speed.-|||-I`m concerned about the cumulative effect of years at these levels of excitable activity.It is-|||-no mystery to me why many teenagers appear apatheri麻木的)and burned out,with a "been-|||-there,done that"air of indifference toward much of life. As increasing numbers of friends`-|||-children are prescribed medications-stimulants to deal with inattentiveness at school or anti--|||-depressants to help with the loss of interest and joy in their lives - I question the role of kids`-|||-boredom in some of the diagnoses.-|||-My own work is focused on the chemical imbalances and biological factors related to-|||-behavioural and emotional disorders. These are complex problems. Yet I`ve been reflecting-|||-more and more on how the pace of life and the intensity of stimulation may be contributing to-|||-the rising rates of psychiatric problems among children and adolescents in our society.-|||-() 63.The author tells surprised in the amusement park at fact that __-|||-A.his son was not as thrilled by the roller coasters ride as expected-|||-B.his son blasted through the turns and loops with his face stretched-|||-C.his son appeared distressed but calm while riding the roller coasters-|||-D.his son could keep his balance so well on the fast moving roller coasters-|||-() 64.According to the author,children are bored __-|||-A.unless their parents can find new thrills for them-|||-B.when they don`t have any access to stimulating fun games-|||-C.when they are left alone at weekends by their working parents-|||-D.even if they are exposed to more and more kinds of entertainment-|||-() 65.From his own experience, the author came to the conclusion that children seem to-|||-expect __ _。-|||-A.a much wider variety of sports facilities-|||-B.activities that require complex skills-|||-C.ever-changing thrilling forms of recreation-|||-D.physical exercises that are more challenging-|||-() 66.In Paragraph 6 the author expresses his doubt about the effectiveness of trying to-|||-change children`s indiffe toward much of life by __ _.-|||-A.diverting their interest from electronic visual games-|||-B.prescribing medications for their temporary relief-|||-C.creating more stimulating activities fo them-|||-D.spending more money on their entertainment
