The Ice Age
Twenty thousand years ago, the earth was held in control by relentlessly (不宽容地) probing fingers of ice that drew power from frigid strongholds in the north and crept southwestward to bury forests, fields, and mountains. Landscapes that were violated by the slowly moving glaciers(冰川)would carry the scars of this advance far into the future. Temperatures dropped deeply, and land surfaces in many parts of the world were depressed by the unrelenting weight of the thrusting ice. At the same time, so much was drawn from the oceans to form. these huge glaciers that sea levels around the world fell by three hundred and fifty feet, and large areas of the continental shelf became dry land.
This period of the Earth's history had come to be called the Ice Age. In all, about eleven million square miles of land were covered with ice. The Ice Age terminated about fourteen thousand years ago when the ice sheets began to retreat. It took about seven thousand years for the ice to retreat to its present level.
There were no human beings on the earth during the Ice Age.

B．Wrong

听力原文：M: Hey, Jane. What's so interesting？
W: What？ Oh, hi, Tom. I'm reading this fascinating article on the societies of the Ice Age.
M: The Ice Age？ There weren't any societies then, just groups of cave people.
W: That's what people used to think. But a new exhibition at the American Museum of National History shows that Ice Age people were surprisingly advanced.
M: Oh, really？ In what way？
W: Well, Ice Age people were the inventors of languages, art and music as we know it. And they didn't live in caves. They built their own shelters.
M: What did they use to build them？ The cold weather would have killed almost all of the trees, so they couldn't have used wood.
W: In some warmer climates, they did build houses of wood. In other places, they used animal bones and skins or lived in natural stone shelters.
M: How did they stay warm？ Animal skin walls don't sound very sturdy.
W: Well, it says here, that in the early Ice Age, they often faced their homes towards the south to take advantage of the sun.
M: Hey, that's pretty smart! I guess I spoke too soon. Can I read that magazine article 'after you're done？
W: No problem.
23. What did the man originally think of the people of the Ice Age？
24.How did people in the early Ice Age keep warm？
25.What does the man want the woman to do？

A．They lived in groups and were cave people.
B．There were societies in Ice Age.
C．They were advanced in arts.
D．They had a smart way of building shelters.

听力原文：M: Hey, Jane! What's so interesting？
W: What？ Oh, hi, Tom! I'm reading this fascinating article on the societies of the Ice Age during the Pleistocene period.
M: The Ice Age？ There weren't any societies then—just a bunch of cave people.
W: That's what people used to think. But a new exhibit at the American Museum of Natural History shows that lee Age people were surprisingly advanced.
M: Oh, really？ In what ways？
W: Well, Ice Age people were the inventors of language, art, and music as we know it. And they didn't live in caves; they built their own shelters.
M: What did they use to build them？ The cold weather would have killed off most of the trees, so they couldn't have used wood.
W: In some of the warmer climates they did build houses of wood. In other places they used animal bones and skins or lived in natural stone shelters.
M: How did they stay warm？ Animgi-skin walls don't sound very sturdy.
W: Well, it says here that in the early Ice Age often faced their homes toward the south to take advantage of the sun—a primitive sort of solar heating.
M: Hey, that's pretty smart.
W: Then people in the late Ice Age even insulated their homes by putting heated cobblestones on the floor.
M: I guess I spoke too soon. Can I read that magazine article after you're done？ I think I'm going to try to impress my anthropology teacher with my amazing knowledge of Ice Age civilization.
W: What a show-off？
(20)
A．They lived in caves.
B．They traveled in groups.
C．They had an advanced language.
D．They ate mostly fruit.

听力原文：M: Congratulations on breaking the records at the recent Olympics, Miss Green!
W: Thank you, Mr Parker.
M: Oh, look at those trophies! You became a swimming star at the age of fifteen, didn't you？
W: Yeah, you're right.
M: Could you tell me something about your plans for the future？
W: To tell you the truth, I'm going to give up swimming from now on.
M: I beg your pardon？
W: I mean I'd rather not swim at all. I'm too old to...
M: Excuse me, if I'm not wrong, you're only twenty now. Is it too old twenty？
W: Yes, too old for a swimmer. If I swim in an international competition, I’ll hardly be able to win.
M: But... er... don't you enjoy swimming？
W: Certainly, and I enjoy visiting other countries, and the Olympics are very exciting. However, I missed more important things. I had to work very hard at swimming. There was training before school, after school, and at weekends. While other girls were growing up, I was swimming, swimming. But life isn't merely swimming, is it？
When did Miss Green become a swimming star？
A．At the age of 15.
B．At the age of 20.
C．At the age of 18.
D．At the age of

听力原文： You can tell the age of a tree by counting its tings. But these records of a tree's life really say a lot more. Scientists are using tree tings to learn what's been happening on the sun's surface for the last ten thousand years. Each ring represents a year of growth. As the tree grows, it adds a layer to its trunk, taking up chemical elements from the air. By looking at the elements in the rings from a given year, scientists can tell what elements were in the air that year.
Dr. Stevenson is analyzing one element, carbon—14, in rings from both living and dead trees. Some of the rings go back almost ten thousand years to the end of the Ice Age. When Stevenson followed the carbon--14 trail back in time, he found carbon—14 levels change with the intensity of solar burning. You see the sun has cycles. Sometimes it bums fiercely. At other times it's relatively calm. During the sun's violent periods, it throws off charged particles in fast moving streams, called solar winds. The particles interfere with the formation of carbon—14 on earth. When there is more solar wind activity, less carbon—14 is produced. Ten thousand years of tree rings show the carbon—14 level rises and falls about every four hundred and twenty years. The scientists concluded that solar wind activity must follow the same cycle.
(30)
A．To find out the origin of carbon- 14 on Earth.
B．To analyze the composition of different trees.
C．To look into the pattern of solar wind activity.
D．To examine the chemical elements in the Ice Age.
