[单选题]There was a river with a small town on either side of it.The towns were linked by a bridge.
One day,a hole appeared in the bridge.Both towns agreed that the hole should be mended.However,disagreement came up as to who should mend it.Each town thought that it had a better?reason for the other to mend the hole.The town on the right bank said that it was at the end of the road,so the left-bank town should mend the hole.The town on the left bank,on the other hand,insisted that?all the traffic came to the right-bank town,so it was in their interest to mend the bridge.
The quarrel went on and on,and so did the hole.The more it went on,the more the hostility?between the two towns grew.
One day a man fell into the hole and broke his leg.People from both towns questioned him?closely about whether he was walking from the right bank to the left or from the left bank to the?right,in order to decide which town should be blamed for the accident.But he could not remember,since he got drunk that night.
Some time later.,a car was crossing the bridge and broke an axle(轴)because of the hole.Neither town paid any attention to the accident,as the traveler was not going from one to the other,but?was merely passing through.The angry traveler got out of the car and asked why the hole was not?mended.
On hearing the reason,he declared,"I′11 buy this hole.Who′s the owner?"
Both towns at once declared that they owned the hole.
"One or the other,whoever owns the hole must prove it."
"How shall we prove it?"asked both sides.
"That′s simple.Only the owner of the hole has the right to mend it.I′11 buy the hole from?whoever mends the bridge."
People from both towns rushed to do the job while the traveler smoked a cigar and his driver?changed the axle.They mended the bridge in no time and asked for the money for the hole.
"What hole?"The traveler looked surprised."I can′t see any hole.I′ve been looking for a?hole for several years now.I′m prepared to pay a good price for it,but there′s no hole here.Are?you pulling my leg or what?"
He got into his car and drove off.

Any organization can use an address out of this set withoutpermission from the Internet authorities. Everyone knows that these reserved addresses are for private networks.They are （） inside the organization, but they are not unique globally. No router will （） a packet that has one of these addresses as the destination address.The site must have only one single connection to the global Internet through a router that runs the NAT software.

[单选题]The Internet affords anonymity to its users,a blessing to privacy and freedom of speech.But that very anonymity is also behind the explosion of cyber-crime that has 1 across the Web.Can privacy be preserved 2 bringing safety and security to a world that seems increasingly 3?Last month,Howard Schmidt,the nation’s cyber-czar,offered the federal government a 4 to make the Web a safer place-a“voluntary trusted identity”system that would be the high-tech 5 of a physical key,a fingerprint and a photo ID card,all rolled 6 one.The system might use a smart identity card,or a digital credential 7 to a specific computer.and would authenticate users at a range of online services.The idea is to 8 a federation of private online identity systems.User could 9 which system to join,and only registered users whose identities have been authenticated could navigate those systems.The approach contrasts with one that would require an Internet driver’s license 10 by the government.Google and Microsoft are among companies that already have these“single sign-on”systems that make it possible for users to 11 just once but use many different services.12.the approach would create a“walled garden”n cyberspace,with safe“neighborhoods”and bright“streetlights”to establish a sense of a 13 community.Mr.Schmidt described it as a“voluntary ecosystem”in which“individuals and organizations can complete online transactions with 14,trusting the identities of each other and the identities of the infrastructure 15 which the transaction runs”.Still,the administration’s plan has 16 privacy rights activists.Some applaud the approach;others are concerned.It seems clear that such a scheme is an initiative push toward what would 17 be a compulsory Internet“drive’s license”mentality.The plan has also been greeted with 18 by some computer security experts,who worry that the“voluntary ecosystem”envisioned by Mr.Schmidt would still leave much of the Internet 19.They argue that all Internet users should be 20 to register and identify themselves,in the same way that drivers must be licensed to drive on public roads.6选？
