Instead of clinging to late-20th-century distribution technologies, like the digital disk and the down- loaded file, the music business should move into the 21st century with a revamped business model using innovative technology, several industry's experts say. They want the music industry to do unto the file-swapping services what the services did unto the music companies—eclipse them with better technology and superior customer convenience.
Their vision might be called "everywhere Internet audio". Music fans instead of downloading files on KaZaA—whether they were using computers, home stereos, radios or handheld devices--would have access to all music the record companies hold in their vaults. Listeners could request that any song be immediately streamed to them via the Internet.
If consumers could do this, the argument goes, they would have no interest in amassing thousands of songs on their hard drives. There would be no "theft" of music, because no one would bother to take possession of the song. To clinch music fans' loyalty to the new system, and make them willing to pay for it, the music companies and the supporting industry would need to provide attractively priced, easy-to-use services to give consumers full access to the hundreds of thousands of songs available to them. Consumers could still ask for song titles or artists, as they do now on KaZaA. But they could also, for example request rock 'n' roll tunes like Hat that appeared for more than three weeks in Billboard's Top 10 during the 1960' s. Or they could ask for early 1990's guitarists that sound like Eric Clapton, or new mists similar in style. to Alanis Morissette.
Requests could be intricate, like asking for music subsequently recorded by the original members of the Lovin's Spoonful. Or they could be simple, like requesting light jazz for dinner-party background music. The system would be interactive and could learn each user's tastes. As listeners voted thumbs up or down to tunes (should they choose to), the service would amend their personal libraries accordingly.
If it worked, it would be as if we each had our own private satellite radio channels—customizable collection of tunes for hundreds of millions of audiences of one. It is a compelling business model, and the current music companies, as the owners of the content, could be at the fore of the system.
A tiny taste of such an approach is available on Internet radio networks like live365.com. On such services, listeners can essentially customize a radio station to their individual tastes. But crucial to the future of everywhere Internet audio, many believe, lies in widespread wireless Internet access, because wireless means portability. "Wireless gives the record companies a chance to do it all over again, and this time get it right," said Jim Griffin, the former head of technology at Geffen Records and now the chief executive of the music publisher Cherry Lane Digital. Mr. Griffin is also a founder of pholist.org, home of an active online discussion of music' s future on the Internet.
Many of the brightest industry insiders, academies, lawyers, musicians, industry critics, broadcasters and venture capitalists assemble at pholist.org daily to debate the music business beyond downloading. Many say wireless holds the key. Myriad portable devices already offer Internet access. Some, like the BlackBerry, maintain an always-on wireless Internet connection. Some business-oriented devices, like the Palm Tungsten, no

A. continue free swapping of files on the Internet
B. continue to use late-20th-century distribution technologies
C. use more advanced technology and provide convenience to customers
D. bring lawsuits against consumers for the music files they download from the Internet

听力原文: The most powerful earthquake to hit China in 30 years is feared to have killed thousands of people in the southwestern province of Sichuan. The official news agency Xinhua says more than 50,000 people may have died.The authorities have launched a major rescue operation, but they are finding it difficult to reach victims because roads have collapsed.
Our correspondent Nick Mackie has just arrived near the epicenter, north of the provincial capital Chengdu, in the middle of the night, when it is 15itch-black, and there is no power at all in the town. Many of the buildings axe badly damaged, some Save collapsed and there were workmen and soldiers working away, trying to clear the debris from some collapsed bail, lings to see if there were people underneath.
What made it hard for the rescue teams to approach the earthquake zone?

A. The quake's destruction to roads.
B. The collapse of the buildings.
C. The torrential rain at night.
D. The loss of electrical power.

SECTION B INTERVIEW
Directions: In this section you will hear everything ONCE ONLY. Listen carefully and then answer the questions that follow. Questions 1 to 5 are based on an interview. At the end of the interview you will be given 10 seconds to answer each of the following five questions.
Now listen to the interview.
听力原文:M: Can wearing sun glasses make you more vulnerable to sunburn? Are there people who can resist the AIDS virus better than others? Can a human body rust to death? In his new book Survival of the Sickest, a Medical Maverick discovers why we need disease. Sharon Moalem explores these and other medical mysteries. Sharon, nice to see you, good morning. Let me dare say, you are an evolutionary biologist and a neural geneticist.
W: That’s right.
M: What is that and why does it make you look at things from different points of view?
W: Well, the evolutionary biologist part, it allows me to understand how our ancestors essentially influence who we are today.So whatever they experienced, be it a plague or a climate change, they adapted, they survived and they passed down those adaptations to us tike skin color or disease.
M: So let’s take a look at this question of "is it possible for people to actually rust to death?" Medically speaking, is it possible?
W: Yes, thank you for asking that question. Ah, it is. Over a million Americans might be at risk from too much iron. Today you absorb too much iron from the diet, and it essentially gets into certain organs and over time can rust them. So if it’s in the liver, it can cause liver cancer.
M: You actually suffer from this.
W: Right.
M: So, this, and the treatment for this sounds a bit barbaric.
W: Well, it’s amazing actually. It’s a simple blood donation.
M: But it’s basically bleeding someway.
W: Right.
M: Well, you’re getting rid of the iron-rich blood so that it can build up slowly again over time.
W: Right.
M: Alright. The second idea, sun exposure, skin disease experts everywhere are gonna be shocked when they ear this, because they say "stay out of the sun, no matter what". And you say "a certain amount of sun exposure actually can make us healthier".
W: Right, essentially, we need vitamin D, so we evolve to convert cholesterol into vitamin D. Those are a few steps to get it and Vitamin D is not just good for the bone, it’s good for the immune system. So take African-Americans for example, who live in the northeastern United States, they’re at higher risk for prostate cancer than their cousins in Florida. And the reason for this is they don’t get enough sun.
M: And another example: the cholesterol levels in people tend to go up in the winter.
W: That’s right.
M: Because you’re not breaking down the cholesterol into vitamin D in the same levels.
W: Exactly.
M: Alright. But this is very individual. You shouldn’t just tell everybody "go out and get in the sun".
W: Oh, no, no. And again this is an example of an evolutionary compromise. You shouldn’t get too much sun, but you still need the sun.
M: You talked about evolution. You talked about genes. And there’s an interesting point you make in the book. If a disease is a disadvantage to survival, in other words, it promotes premature death, then these people live shorter amount of time, they are less likely to reproduce. Why wouldn’t the gene disappear over time?
W: Right. Because it has to be protective. It protected the people in the past from the plague and it still fights to protect people today.
M: How about this one? Wearing sunglasses increases the chance of sunburn. And this is true?
W: Right, this is fascinating. So, our eyes sense sunlight and once they do, they produce a hormone that gets the skin kick started to start the tanning process. And by putting on sunglasses, you are short-circuiting in that process.So you shouldn’t go out into the sun and of course without eyewear, eye protection, but take it off for 10

The inspiration for nanotech goes back to a 1959 speech by the late physicist Richard Feynman, then a professor at the California Institute of Technology, titled "There's Plenty of Room at the Bottom." Four decades later, Chad Mirkin, a Chemistry professor at Northwestern University's $34 million nanotech center, used a nanoscale device to etch most of Feynman's speech onto a surface the size of about 10 tobacco smoke particles.
What accounts for the sudden acceleration of nanotechnology? A key breakthrough came in 1990, when researchers at IBM's Almaden Research Center succeeded in rearranging individual atoms at will. Using a device known as a scanning probe microscope, the team slowly moved 35 atoms to spell the three-letter IBM logo, thus proving Feynman fight. The entire Logo was less than three nanometers.
Soon, scientists were not only manipulating individual atoms but "spray painting" with them as well. Using a tool known as a molecular beam epitaxy, scientists have learned to create ultra fine films of specialized crystals, built up one molecular layer at a time. This is the technology used today to build read-head components for computer hard drives.
The next stage in the development of nanotechnology borrows a page from nature. Building a super-computer no bigger than a speck of dust might seem an impossible task, until one realizes that evolution solved such problems more than a billion years ago. Living ceils contain all sorts of nanoscale motors made of proteins that perform. myriad mechanical and chemical functions, from muscle contraction to photosynthesis. In some instances, such motors may be re-engineered, or imitated, to produce products and processes useful to humans.
How are these biologically inspired machines constructed? Often, they construct themselves, manifesting a phenomenon of nature known as self assembly. The macromolecules of such biological machines have exactly the right shape and chemical binding preferences to ensure that when they combine they will snap together in predesigned ways. For example, the two strands that make up DNA's double helix match each other exactly, which means that if they are separated in a complex chemical mixture, they are still able to find each other easily.
It can be inferred that Richard Feynman has been ______ now.

A. dead
B. decent
C. prominent
D. popular
