听力原文： Voice One: A bottlenose dolphin named Maui plays a computer game, helping scientists create a unique language [that] they hope humans and dolphins will understand.
It's not based on human words, but on a specific dolphin sound. Guess which one. Not its bark, or its clicks, made famous by Flipper. Words in this new language are whistled.
Dolphins typically whistle to each other under water, through a special structure just beneath their blowhole. Researchers say their whistles have meaning. For example, each dolphin learns from its mom its own signature whistle. So in human terms when they greet each other, it's not just, "Hi" It's, "Hi, my name is ..."--in this case, Maui.
Ken Marten and his team at Earthtrust in Sea Life Park Research Lab in Hawaii want to better understand how dolphins communicate. So for the next ten years, they will literally whistle while they work, creating this special language.
Voice Two: The rest of my career is dedicated to talking to these guys, so I guess you could call me Doctor Dolittle now.
Voice One: After studying dolphin whistles, Marten invented distinct whistles for various objects with which dolphins are familiar.
Which sound can be thought as dolphin's words？
A．Its bark.
B．Its clicks.
C．Its whistle.
D．Its crying.
听力原文： Not long ago, some of you may have read about a team of mountain-climbing scientists who helped to recalculate the elevation of the highest mountain in the world: Mr. Everest. Of course, the elevation of Mt. Everest was determined many years ago, using traditional surveying methods. But these scientists wanted to make a more precise measurement using a new method that takes advantage of recent advances in technology. It's called the Global Positioning System. The Global Positioning System uses 24 satellites that circle the Earth. Each of these satellites is constantly sending out signals. And each signal contains important information that can be used to determine the longitude, latitude, and elevation of any point on the Earth's surface. Well, in order to use this system to calculate Mt. Everest's elevation, scientists needed to put a special receiver on its summit to receive signals from the satellites. The problem with this was that, in the past, the receivers were much too heavy for climbers to carry. But now these receivers have been reduced to about the size and weight of a hand-held telephone, so climbers were able to take a receiver to the top of Everest and, from there, to access the satellite system signals that would allow them to determine the precise elevation. And it turns out that the famous peak is actually a few feet higher than was previously thought.
Q. 23. What is the talk mainly about？
Q. 24.Why does the speak mention a hand-held telephone？
Q. 25.According to the talk, what probably contributed most to the success of the new study of Mount Everest？
Q. 26.In the study described, how were satellites' signals used？

B．Using satellites to communicate with mountain climbers.
C．Obtaining new information about a mountain.
D．Controlling satellites from the top of a mountain.

A.The Economist

听力原文： Why don't birds get lost on their long flights from one place to another？ Scientists have puzzled over this question for many years. Now they are beginning to fill in the blanks.
Not long ago, experiments showed that birds rely on the sun to guide them during daylight hours. But what about birds that fly by night？ Tests with artificial stars have proved that certain night-flying birds are able to follow the stars in their long-distance flights.
A dove had spent his lifetime in a cage and had never flown under a natural sky. Yet it showed an inborn ability to use the stars for guidance. The bird's cage was placed under an artificial star-filled sky. The bird tried to fly in the same direction as that taken by his outdoor cousins. Any change in the position of the artificial stars caused a change in the direction of his flight.
But the stars are apparently their principal means of navigation. When the stars are hidden by clouds, they apparently find their way by such landmarks as mountain ranges, coast lines, and river courses. But when it's too dark to see these, the doves circle helplessly, unable to find their way.
The reason why birds don't get lost on long flights ______.
A．has been known to scientists for years
B．has only recently been discovered
C．is known by everyone
D．will probably remain a mystery
Mo Yan is ______ Nobel Prize.
A: famous as
B: famous for
C: famous to
D: famous of
