第一篇 Valuing Childhood
The value of childhood is easily blurred(变得模糊不清)in today's world．Consider some recent developments：The child．murderers in 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．
Children who commit horrible crimes appear to act of their own will．Yet，as legal proceedings in Jonesboro showed，the one boy who was able to address the court couldn't begin to explain his acts．though he tried to apologize．There may have been a motive-youthful jealousy(妒忌)and resentment．But a deeper question remains：Why did these boys and others in similar trouble apparently lack any inner,moral restraint?
That question echoes for the accused in Chicago．young as they are．They wanted the girl's bicycle,a selfish impulse common enough among kids．
Redemption(拯救)is a practical necessity．How can value be restored to young lives distorted by acts of violence?The boys in Jonesboro and in Chicago will be confined in institutions for a relatively short time．Despite horror at what was done，children are not-cannot be-dealt with as adults．not if a people wants to consider jtself civilized．That's why politicians'cries for adult treatment of youthful criminals ultimately miss the point．
But the moral void(真空)that invites violence has many sources．Family instability contributes：So does economic stress．That void．however,can be filled．The work starts wifh
parents，who have to ask themselves whether they're doing enough to give their children a firm sense of right and wrong．Are they really monitoring their activities and their developing processes of thought?
Schools．too,have a role in building character．So do youth organizations．So do law enfomement 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 children 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 don't go that far,but who 1ack the moral foundations childhood should provide-and which progressive human society relies on．

第二篇 Hacking
People tend to think of computers as isolated machines，working away all by themselves.Some do-personal computer without an outside link，like Someone's hideaway(隐蔽的)cabin in the woods．But just as most homes are tied to a community by streets，bus routes and electric lines．computers that exchange intelligence are part of a community-local，national and even global network joined by telephone connections．
The computer network is a creation of the electric age，but it is based on old-fashioned trust. It cannot work without trust．A rogue loose(为所欲为的无赖)in a computer system called hacker (黑客) is worse than a thief entering your house．He could go through anyone's electronic mail or add to，change，distort or delete anything in the information stored in the computer's memory．He could even take control of the entire system by placing his own instructions in the software that runs it．He could shut the computer down whenever he wished，and no one could stop him．Then he could program the computer to erase any sign of his ever having been there.
Hacking，our electronic-age term for computer break-in，is more and more in the news-brainy kids vandalizing university records，even pranking(胡闹)about in supposedlyline14
safeguarded systems．To those who understand how computer networks are increasingly regulating life in the late 20th century,these are not laughing matters．A potential for disaster is
building：A dissatisfied former insurance-company employee wipes out information trom payroll (工资表) files．A student sends out a"virus"，a secret and destructive command，over a national network．The virus copies itself at lightning speed，jamming the entire network-thousands of academic，commercial and govemment computer systems．Such disastrous cases have already occurred．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 against attack．For one thing，such defenses are expensive；for another,they may interrupt communication -the main reason for using computers in the first place.
