听力原文：M: Hello. This is Greg Rice reporting live in Barrow. Alaska.
W: Hello. Greg. Is everything going smoothly？
M: Yes. I've just arrived here in Barrow. Alaska, to bring you live coverage of what appears to be the results of a huge meteorite impact, perhaps the largest in recent history, that occurred just twelve hours ago. The exact location of the impact is unknown, but estimates put it about 20 kilometers south of Barrow based on shock waves felt throughout the region.
W: Are there any witnesses？
M: Yeah. Some witnesses say they saw a bright light streaking through the sky, accompanied by a mating boom, moments before the impact. It's unknown whether there are any casualties, but it is unlikely considering this sparsely populated area.
W: It's said that such impacts were commonplace during the formation of our solar system, and many believe that a meteorite 10 kilometers in diameter which crashed into Earth 65 million years ago led to the mass extinction of many animal species including the dinosaurs.
M: You're right. But R is often difficult to calculate the number of such large impacts on Earth because erosion and vegetation make it difficult to spot them. In recant years, astronomers have focused more of their attention on the paths of many uncharted space rocks or asteroids floating out there in the hope that we might be able to determine the threat they pose on mankind...This is Greg Rice reporting from Alaska.
W: Thanks, Greg...We'll keep you up-to-date on any development there.

听力原文： You may remember that a few weeks ago, we discussed the question of what photography is. Is it art, or is it a method of reproducing images？ Do photographs belong in museums or just in our homes？ Today I want to talk about a person who tried to make his professional life an answer to such questions.
Alfred Stieglitz went from the United States to Germany to study engineering. While he was there, he became interested in photography and began to experiment with his camera. He took pictures under conditions that most photographers considered too difficult—he took them at night, in the rain, and of people and objects reflected in windows. When he returned to the United States, he continued these revolutionary efforts. Stieglitz was the first person to photograph skyscrapers, clouds, and views from an airplane.
What Stieglitz was trying to do in these photographs was what he tried to do throughout his life: make photography an art. He felt that photography could be just as good a form. of self expression as painting or drawing. For Stieglitz, his camera was his brush. While many photographers of the late 1800' s and early 1900' s thought of their work as a reproduction of identical images, Stieglitz saw his as a creative art form. He understood the power of the camera to capture the moment. In fact, he never retouched his prints or made copies of them. If he were in this classroom today, r m sure he' d say, "Well, painters don' t normally make extra copies of their paintings, do they？"
