30、n the Jonesboro, Ark. schoolyard shooting case were convicted and sentenced. Two boys, 7 and 8, were charged in the murder of an 11-year-old girl in Chicago.

Thats why politicians cries for adult treatment of youthful criminals ultimately miss the point. But the moral void (真空 ) that

34、invites violence has many sources. Family instability contributes. So does economic stress. That void, however, can be filled. The work starts with parents, who have to ask themselves whether theyre doing enough to give their children a firm sense of right and wrong. Are they really monitoring their

35、 activities and their developing processes of thought? Schools, too, have a role in building character. So do youth organizations. So do law enforcement agencies, which can do more to inform the young about laws, their meaning, and their observance (遵守 ). The goal, ultimately, is to allow all childr

36、en a normal passage from childhood to adulthood (成年 ), so that tragic gaps in moral judgement are less likely to occur. The relative few who fill such gaps with acts of violence hint at many others who dont go that far, but who lack the moral foundations childhood should provide and which progressiv

42、d hacker (黑客 ) is worse than a thief entering your house.

The virus copies itself at lightning speed, jamming the entire network thousands of academic, commercial and government computer systems. Such disastrous cases have already occ

46、urred. Now exists the possibility of terrorism by computer. Spoiling a system responsible for air-traffic control at a busy airport, or knocking out the telephones of a major city, is a relatively easy way to spread panic. Yet neither business nor government has done enough to toughen its defenses a

47、gainst attack.
