● Serialization delay and （71） delay are the two components of network delay that are improved by increasing bandwidth. Serialization delay, i.e. the amount of time it takes to put the （72） on the wire, and queuing delay (depth of the queue) are improved by increasing the （73） from a 128Kbps circuit to a T1. However, three other components of delay, routing/switching delay, distance delay, and protocol delay are components that can not be positively affected by an （74） in bandwidth. If the circuits are not over-utilized, then increasing the bandwidth to improve the （75） of the application will only result in an increased bandwidth with no positive effects on performance.

听力原文：W: Um, I'll read it for you. Yes, it's a large textile company that seems to import from abroad. That's odd, isn't it? What else?... A sales assistant is needed. They say the salary is really good. They operate a system of paying you a basic salary and then offering extra money for selling more, They say it is high. And, oh, look! They give you a car to travel round in. Gosh! That's not bed, is it?

M: Um, do they say anything about experience?

W: Urn, let's see. No, they want someone young with ambition and enthusiasm. Oh yes, they want graduates, so that's OK. You've been to university. Now what else? Let's see.

M: There must be some trick.

W: No, the only thing is that you have to travel, but then the company takes care of that. Oh, and you have to be able to get well with other people. It says that you have to be good in a team.

M: Um, perhaps I'll have a closer look at that one.

D．Being interviewed for a job in a company.

听力原文：M: Of the two cars we have seen, which one do you think fits our needs better, the first one or the second one?

W: The second one. It seems very expensive, but in the long run it will save us a lot of money.

Q: What does the woman say about the reason for her choice?

(19)

A．The first car they saw is too expensive.

B．They may save some money for the time being.

C．She is happy with the price set by the seller.

D．Less money will be spent in the long run.

听力原文： One of the banks worst hit by the international credit crisis,, the Citigroup, has outlined plans to dramatically reduce the size of its business. The bank's Chief Executive Vikram Pandit wants to dispose of assets worth about $400 billion over the next three years. The BBC economic correspondent says the plan appears to be to sell off less profitable part of its operation. Citigroup has recorded losses of 15 billion in the last six months.

What is the main idea of the news item?

A．The Citigroup has been worst hit by the international credit crisis.

B．The Citigroup has already started to reduce the size of its business.

C．The Citigroup has encountered great losses in the credit crisis.

D．The Citigroup has decided to take measures to deal with great losses.

Directions: Read the following four texts. Answer the questions below each text by choosing A, B, C or D. (40 points)

It was the biggest scientific grudge match since the space race. The Genome Wars had everything: two groups with appealing leaders ready to fight in a scientific dead heat, pushing the limits of technology and rhetoric as they battled to become the first to read every last one of the 3 billion DNA "letters" in the human body. The scientific importance of the work is unquestionable. The completed DNA sequence is expected to give scientists unprecedented insights into the workings of the human body, revolutionizing medicine and biology. But the race itself, between the government's Human Genome Project and Rockville, Md., biotechnology company Celera Genomics, was at least partly symbolic, the public/private conflict played out in a genetic lab.

Now the race is over. After years of public attacks and several failed attempts at reconciliation, the two sides are taking a step toward a period of calm. HOP head Francis Collins (and Ari Patrinos of the Department of Energy, an important ally on the government side) and Craig Venter, the founder of Celera, agreed to hold a joint press conference in Washington this Monday to declare that the race was over (sort of), that both sides had won (kind of) and that the hostilities were resolved (for the time being).

No one is exactly sure how things will be different now. Neither side will be turning off its sequencing machines any time soon—the "finish lines" each has crossed are largely arbitrary points, "first drafts" rather than the definitive version. And while the joint announcement brings the former Genome Warriors closer together than they've been in years, insiders say I that future agreements are more likely to take the form. of coordination, rather than outright collaboration.

The conflict blew up this February when Britain's Welcome Trust, an HGP participant, released a confidential letter to Celera outlining the HGP's complaints. Venter called the move "a lowlife thing to do", but by spring, there were the first signs of a thaw. "The attacks and nastiness are bad for science and our investors", Venter told Newsweek in March, "and fighting back is probably not helpful". At a cancer meeting earlier this month, Venter and Collins praised each other's approaches, and expressed hope that all of the scientists involved in sequencing the human genome would be able to share the credit By late last week, that hope was becoming a reality as details for Monday's joint announcement were hammered out. Scientists in both camps welcomed an end to the hostilities. "If this ends the horse race, science wins". With their difference behind them, or at least set aside, the scientists should now be able to get down to the interesting stuff, figuring how to make use of all that data.

The recent Genome Wars were symbolic of

A．the enthusiasm in scientific research.

B．the significance of the space race.

C．the public versus private conflict.

D．the prospect of the completion of DNA sequene.
