1、The US military has blocked public access to nearly all its web sites after its servers were attacked by a new computer virus. Late last week, the US Space Command, which provides security for military computers, instructed all military organizations to block public access after a number of sites ha

2、d contracted the virus, called the Code Red bug, according to an official.The virus is known as a denial of service bug, because it replicates (自我复制) itself by reading the data files on a network server and sending copies to other serversthereby multiplying and sometimes crashing a systemand denying

3、 access to legitimate (合法的) users of the site.The Code Red worm did in fact show up in some DoD (Department of Defense) web sites and were working to contain that, Command Spokesman Army Maj. Barry Venable said. Ways were going about that include blocking public access to the Web sites, because that

4、s the way this worm works, to prevent it from using our networks to propagate (繁殖) itself.The virus exploits a security flaw (缺陷) in certain Microsoft network servers. The flaw was announced last month when a patch was released to fix it.To protect our DoD web sites from being compromised, DoD organ

5、izations have been told to review the status of the Internet information servers. to make sure that all the patches that were previously installed had been installed, says Venable.Only a handful of the major Defense Department sites, with the suffix .mil, appear currently accessible to the public, i

6、ncluding the central public affairs site DefenseLink and the military services main homepages. Public access is blocked to information connected to those sites, and others such as the National Missile Defense site and the US Air Forces European site. Registered Department of Defense personnel contin

It may make a computer system stop working.C. Its included in a patch released by Microsoft.D. It may destroy

9、the connection between legitimate users and the sites.4.Public access is blocked to most DoD web sites so that _.A. the Code Red worm cant use the web site to replicates itself and send copiesB.

11、. Having necessary patches installed.Questions 6 to 10 are based on the same passage or dialog.For an increasing number of students at American universities, old is suddenly in. The reason is obvious: the graying of America means jobs. Coupled with the aging of the baby-boom (生育高峰) generation, a lon

12、ger life span means that the nations elderly population is bound to expand significantly over the next 50 years. By 2050, 25 percent of all Americans will be older than 65, up from 14 percent in 1995. The change poses serious questions for government and society, of course. But it also creates caree

13、r opportunities in medicine and health professions, and in law and business as well. In addition to the doctors, were going to need more sociologists, biologists (生物学家), city planners and specialized lawyers, says Professor Edward Schneider of the University of Southern Californias (USC) School of G

14、erontology (老年学). Lawyers can specialize in elder law, which covers everything from trusts and estates to nursing-home abuse and age discrimination (歧视). Businessmen see huge opportunities in the elder market because the baby boomers, 74 million strong, are likely to be the wealthiest group of retir

15、ees in human history. Any student who combines an expert knowledge in gerontology with, say, an MBA or law degree will have a license to print money, one professor says.Margarite Santos is a 21-year-old senior at USC. She began college as a biology major but found she was really bored with bacteria.

16、 So she took a class in gerontology and discovered that she liked it. She says, I did volunteer work in retirement homes and it was very satisfying.6.The words . old is suddenly in (Para. 1) most probably means _.A. America has suddenly become a nation of old peopleB. gerontology has suddenly become

17、 popularC. more elderly professors are found on American campusesD. American colleges have realized the need of enrolling older students7.With the aging of America, lawyers can benefit _.A. from the adoption of the elder lawB. from rendering special services to the elderlyC. by enriching their profe

18、ssional knowledgeD. by winning the trust of the elderly to promote their own interests8.Why can businessmen make money in the emerging elder market?A. Retirees are more generous in spending money.B. They can employ more gerontologists.C. The elderly possess an enormous purchasing power.D. There are

19、more elderly people working than before.9.Who can make big money in the new century according to the passage?A. Retirees who are business-minded.B. The volunteer workers in retirement homes.C. College graduates with an MBA or law degree.D. Professionals with a good knowledge of gerontology.10.It can

20、 be seen from the passage that the expansion of Americas elderly population _.A. will provide good job opportunities in many areasB. will impose an unbearable burden on societyC. may lead to nursing home abuse and age discriminationD. will create new fields of study in universitiesQuestions 11 to 15

21、 are based on the same passage or dialog.The decline in moral standardswhich has long concerned social analystshas at last captured the attention of average Americans. And Jean Bethke Elshtain, for one, is glad. The fact that ordinary citizens are now starting to think seriously about the nations mo

22、ral climate, says this ethics (伦理学) professor at the University of Chicago, is reason to hope that new ideas will come forward to improve it.But the challenge is not to be underestimated. Materialism and individualism in American society are the biggest obstacles. The thought that Im in it for me ha

23、s become deeply rooted in the national consciousness, Ms. Elshtain says.Some of this can be attributed to the decay of traditional communities, in which neighbors looked out for one another, she says. With todays greater mobility and with so many couples working, those bonds have been weakened, repl

24、aced by a greater emphasis on self.In a 1996 poll of Americans, loss of morality topped the list of the biggest problems facing the US. And Elshtain says the public is correct to sense that: Data show that Americans are struggling with problems unheard of in the 1950s, such as classroom violence and

25、 a high rate of births to unmarried mothers.The desire for a higher moral standard is not a lament (挽歌) for some nonexistent golden age, Elshtain says, nor is it a wishful (一厢情愿的 ) longing for a time that denied opportunities to women and minorities. Most people, in fact, favor a decrease in prejudi

26、ce.Moral decline will not be reversed until people find ways to counter the materialism in society, she says. Slowly, you recognize that the things that matter are those that cant be bought.11.Professor Elshtain is pleased to see that Americans _.A. have adapted to a new set of moral standardsB. are

27、 longing for the return of the good old daysC. have realized the importance of material thingsD. are awakening to the lowering of their moral standards12.The moral decline of American society is caused mainly by _.A. its growing wealthB. the self-centeredness of individualsC. underestimating the imp

28、act of social changesD. the prejudice against women and minorities13.Which of the following characterizes the traditional communities?A. Great mobility. B. Emphasis on individual effort.C. Concern for ones neighbors. D. Ever-weakening social bonds.14.In the 1950s, classroom violence _.A. was somethi

29、ng unheard ofB. attracted a lot of public attentionC. was by no means a rare occurrenceD. began to appear in analysts data15.According to Elshtain, the current moral decline may be reversed _.A. if people can return to the golden ageB. when women and men enjoy equal rightsC. when people rid themselv

30、es of prejudiceD. if less emphasis is laid on material thingsLocked Away ForeverThe Sad Case of Rebecca FalconOne night when she was just 15, Rebecca Falcon got drunk and made the decision that ruined her entire life. Now, she is serving a life sentence without chance of parole (假释) at the Lowell Co

31、rrectional Institution in Ocala, Florida. Looking back, Falcon faults her choice of friends.I was like a magnet for the wrong crowd, she says.At the time, Falcon was living with her grandmother in Panama City, Florida. On November 19, 1997, upset over an ex-boyfriend, she downed a large amount of al

32、cohol and hailed a taxi with an 18-year-old friend. Her friend had a gun and, within minutes, the taxi driver was shot in the head. The driver, Richard Todd Phillips, 25, died several days later. Each of the teenagers later said the other had done the shooting.In Falcons case, she was found guilty o

33、f murder, though it was never known precisely what happened. It broke my heart, says Steven Sharp, one of the people who made the decision to send Falcon to prison. Tough as it is, based on the crime, I think its appropriate. Still, its terrible to put a 15-year-old behind bars forever.Falcons case

34、is not so uncommon in the US, but it is rare around the world. About 9,700 American prisoners are serving life sentences for crimes they committed before age 18. More than a fifth have no chance for parole. Life without parole is available for young criminals in about a dozen countries, but a recent

35、 report by Human Rights Watch and Amnesty International found only 12 young criminalsin Israel, South Africa, and Tanzaniaserving such sentences. In the U.S., more than 2,200 people are serving life without parole for crimes they committed before turning 18. More than 350 are 15 or younger.Cruel & U

36、nusual?Young criminals are serving life terms (with or without the possibility of parole) in at least 48 states, according to a survey by The New York Times, and their numbers have increased sharply in the past decade. Of those imprisoned in 2001, 95 percent were male and 55 percent were black.Is su

37、ch punishment fair for young offenders? In March 2005, the Supreme Court ruled that the death penalty for crimes committed by people under 18 violates the Eighth Amendment to the Constitution, which prohibits cruel and unusual punishments. That might have surprised the people who agreed to the Amend

38、ment in 1791, many of whom found such executions neither cruel nor unusual. But the Court said that the meaning of the Amendment changes with evolving standards of decency. Their decision has convinced lawyers and activists that the next legal battleground in the US will be over life sentences for y

39、oung criminals.Unformed PersonalitiesThe Supreme Court ruled that youths under 18 who commit terrible crimes are less blameworthy than adults, at least for purposes of the death penalty: They are less mature, more willing to give in to peer pressure, and their personalities are unformed. Even a terr

40、ible crime committed by a young person, Justice Anthony M. Kennedy concluded, is not evidence of a hopelessly evil character.Most of those youthful qualities were evident in Falcon, who had trouble fitting in at school. She is in prison for murder, meaning she participated in a crime that led to a k

41、illing but was not proved to have killed anyone.Jim Appleman, the lawyer that tried to put Falcon in jail, says she does not ever deserve to be free. He is convinced that she shot Phillips. If she were a 29-year-old or a 22-year-old, he says, I have no doubt she would have gotten the death penalty.A

42、lthough Falcon believes her sentence is unfair, she says her eight years in prison have changed her. A certain amount of time being in jail was what I needed, she says. But the law I fell under is for people who have no hope of being changed for the better, career criminals who habitually break the

43、law, and theres just no hope for them in society. Im a completely different case.This can be hardThe case of another Florida teenager, Timothy Kane, shows how youths can be sent away for life, even when they were not central figures in a crime. (Florida is among the states with the largest number of

44、 young offendersabout 600serving life sentences, about 270 without parole.)On Jan. 26, 1992, Kane, then 14, was playing video games at a friends house in Hudson, Florida, while some older boys planned a robbery. That night, five youths rode their bikes over to a neighbors home. Two backed out, but K

45、ane followed Alvin Morton, 19, and Bobby Garner, 17, into the house. He did not want others to think he was scared, he recalls. This is the decision that shaped my life since, says Kane.He says he thought the house would be empty. But Madeline Weisser, 75, and her son, John Bowers, 55, were home. Wh

46、ile Kane hid behind a dining-room table, Morton shot and killed Bowers. He then stuck a knife in Weissers neck; Garner stepped on the knife, nearly cutting off her head.Morton was sentenced to death. Garner, like Kane, a young offender, was given a life sentence with no possibility of parole for 50

47、years. Kane was also sentenced to life, but he may be able to get parole after serving 25 years. He doubts that the parole board will ever let him out.Kane grows emotional when talking about that January night. I witnessed two people die, he says. I regret that every day of my life, being any part o

48、f that and seeing that. He does not dispute that he deserved punishment but says his sentence is harsh. His days at Sumter Correctional Institution in Bushnell, Florida, are spent in the prison print shop making 55 cents an hour. You have no hope of getting out, Kane says. You have no family. You have no moral support here. This
