听力原文: Surtsey was born in 1963. It was a great event for scientists. They were lucky enough to see the birth of this volcanic island. It began at 7: 30 a.m. on 14th November. A fishing boat was sailing near Iceland. The boat moved under the captain's feet. He noticed a strange smell. He saw some black smoke. A volcano was erupting. The bottom of the grey Atlantic was open. Red-hot rocks, flames and smoke were rushing up from a split in the sea-bed. The island grew quickly. It was 10 meters high the next day and 60 meters high on 18th November. Scientists flew to Reykiavik to watch. It was very exciting. Smoke and flames were still rushing up. Pieces of red-hot rock were flying into the air and falling into the sea. The sea was boiling and there was a strange light in the sky. Surtsey grew and grew. Then it stopped in June 1967. It was 175 meters high and 2 kilometers long. And life was already coming to Surtsey. Seeds came over the sea. Plants grew. Birds came. Some scientists built a house to learn about the young island. A new island is like a new world.

M: Yes, Unfortunately, that's a common problem with books made from wood pulp.
W: I suppose that to make paper from wood you have to add a lot of chemicals and acids to make it tam white.
M: Exactly, and it's the acid that eventually eats away the paper.
W: Oh, that actually makes sense, but this book's not even 75 years old and I've seen books in museum that are hundreds of years old and they're in fine condition.
M: Well, you see, books have been made from wood pulp only since the 1850s, before that they were made from materials mostly animals' skins, and no chemicals were added.
W: It's a shame those older wood pulp books are going to fall apart some day. is there anything that can be done to preserve them?
M: En, currently the only way to stop the books from decaying is to remove the binding and treat each page individually to remove the acid.
W: That doesn't sound very economical.
M: No, it isn't. It's not practical to treat a large number of books with this process, so we only try to rescue the most valuable edition books in our collection.
W: Well, thanks for the explanation. I'd better got back to my project.
M: Good luck and I hope the old book will hold long enough for you to finish it.

In the center of the main road into the town he placed a very large stone. Then he hid behind a tree end waited. Soon en old man came along with his cow.
"Who put this stone in the center of the road?" said the old man, but he did not try to remove the stone. Instead, with sane difficulty he passed around the stone and continued tm his way. Another man came along and did the same thing, then another came, and another. All of them complained about the stone in the center of the road but not one of them tried to remove it. Late in the afternoon a young man came along. He saw the stone and said. "The night will be very dark. Sane neighbor will come along later in the dark and will fall against the stone."
The young man then began to move the stone. He pushed and pulled with all his strength to remove it. How great was his surprise at last when, under the stone, he found a bag of money and a piece of paper with these words: "This money is for the first honest man who removes this stone from the road."

"Ah, yes," replied the manager, "but America has treasures that Japan can never hope to possess."
"You mean our mineral wealth and bountiful farms?
"Ah, no. I was referring to Caltech and MIT."
America's scientific institutions--its technological universities and government laboratories--are the en vy of the world , producing ideas, devices and medicines that have made the U.S. prosperous, improved the lives of people around the globe and profoundly affected their perception of the world and the universe. This tremendous creativity is reflected in tile technical reports that are published in scientific journals throughout the world. Fully 35 % of them come from scientists doing their research at American institutions.
Yet American dominance can no longer be taken for granted. Many recent U. S. achievements and a wards stem in large measure from generous research grants of the past, and any weakening of government and industry commitment to support of basic research could in the next few decades cost the nation its scientific leadership. Some slipping is already divalent. In high-energy physics, where Americans once reigned supreme, Western Europe now spends roughly twice as much money as the U. S. Result. the major high-energy physics discoveries of tile past few years have been made not by Americans but by Europeans.
Even so, money alone cannot guarantee scientific supremacy. Freedom of inquiry, an intellectually stimulating environment and continuous recruitment of the best minds must accompany it. That combination has been achieved in many U.S. institutions--educational, governmental and industrial--but perhaps no where more successfully than at the National Institutes of Health, Bell Laboratories and Caltech.
America's technological universities and government laboratories are generally ______.
A.loved by scientists in other parts of the world
B.disliked by scientists in other parts of the world
C.admired by scientists in other parts of the world
D.jealous of scientists in other parts of the world
M: Actually, he was both highly intelligent and very rich. At first, Frida's father was against her marrying Diego because he was from an infamous family. But later on he agreed to it because he couldn't pay his daughter's medical expenses any more. Frida must have spent a fortune on doctors and operations over the years.
W: Oh, yes, what a terrible life first polio and then that awful accident. It's amazing she produced so many paintings, isn't it?
M: Yes, she must have been an incredibly brave woman.
W: But the marriage didn't work out too well, did it?
M: Well, it had its ups and downs.
W: She painted this one with the cropped hair while they were separated, didn't she?
M: Yes, that's right.
W. She really looked like a man here. In fact, she looked as if she's got a moustache! And why was she dressed in a man's suit? I thought it might have had something to do with women's liberation. You know she cut off her hair to symbolize equality or something.
M: Er, no the reason she cut off her hair and put on a man's suit is because Diego Rivera loved her long hair, and also loved the traditional women's Mexican dresses she used to wear. She did it to hurt him.
