Article: Geologists have been studying volcanoes for a long time.Though they have learned a great deal,they still have not discovered the cause of volcanic action.They know that the inside of the earth is very hot,but they are not sure exactly what causes the great heat.Some geologists have thought that the heat is caused by the great pressure of the earth's outer layers.Or the heat may be left from the time when the earth was formed.During the last sixty years scientists have learned about radium,uranium,thorium,and other radioactive elements.Many scientists now believe that much of the heat inside the earth is produced by radioactive elements. Whatever the cause of the heat may be,we do know that the earth gets hotter the farther down we dig.In deep mines and oil wells the temperatures rise about 1degF for every 50 feet.At this rate of the temperature 40 miles below the earth's surface should be over 4 000deg.This is much hotter than necessary to melt rock.However,the pressure of the rock above keeps most materials from melting at their usual melting points.Geologists believe that the rock deep in the earth may be plastic,or puttylike .In other words,the rock yields slowly to pressure but is not liquid.But if some change in the earth's crust releases the pressure,the rock melts.Then the hot,liquid rock can move up toward the surface. Question: The cause for the great heat inside of the earth is _ . Options: A: great pressure of the earth's outer layers B: the heat left from the time when the earth was formed C: radioactive elements giving out heat D: not sure

I was with my father on a business-and-pleasure trip, and in our leisure hours we were having a wonderful time. "I wish Mother were here, " I said. "If your mother had come with us, " said Father, "it would have been wonderful to show her around." He had visited Denmark when he was a young man. I asked him, "How long is it since you were here?" "Oh, about thirty years. I remember being in this very inn, by the way." He looked around, remembering. "Those were pleasant and enjoyable days..." He stopped suddenly, and I saw that his face was pale. I followed his eyes and looked across the room to a woman who was setting drinks before some customers. She might have been pretty once but now she was fat and her hair was untidy. "Do you know her?" I asked. "I did once," he said. The woman came to our table. "Drinks?" she asked. "We'll have beer," I said. She nodded and went away. "I couldn't believe it! How she has changed! Thank heaven she didn't recognize me," father said in a low voice, mopping his face with a handkerchief. "I knew her before I met your mother," he went on. "I was a student, on a tour. She was a lovely young girl, very graceful. I fell madly in love with her, and she with me." "Does Mother know about her?" I said suddenly, without thinking. "Of course," Father said gently. He looked at me a little anxiously. I felt embarrassed for him. I said, "Dad, you don't have to..." "Your mother would tell you if she were here. I don't want you wondering about this. I was a foreigner to her family. I was dependent on my father. If she had married me, she wouldn't have had any prospects . So her father objected to our romance. When I wrote to my father that I wanted to get married he cut off my allowance . And I had to go home. But I met the girl once more, and told her I would return to America, borrow enough money to get married and come back for her in a few months." "We...

As it nears its second century, the Park Service plans to increase its educational programs for students and teachers. The plans include transportation support for one hundred thousand students each year to visit national parks to learn about nature and history. Yellowstone is believed to have been the world's first national park when it was established in 1872. Other students will get a chance to see parks in faraway places through Skype and other online programs. The National Park Service also works with partners to provide education. One of its partners is a nonprofit organization called NatureBridge. NatureBridge is celebrating its fortieth anniversary and says one million young people have taken part in its programs. The organization works with students from kindergarten through twelfth grade and uses national parks as its classrooms. It provides field science programs at Yosemite National Park and four other locations in California and the northwestern state of Washington. Now, NatureBridge is launching an East Coast center with a four-million-dollar grant from Google. The program will begin in April at the Prince William Forest Park in Virginia. Students stay for three to five days in NatureBridge programs. The activities are aimed at developing their science skills. For example, they learn about different soils and study water quality under a microscope. Jason Morris, executive vice president of NatureBridge says when they are not sleeping, eating or in a laboratory, the students spend their time outdoors. Julia Washburn is associate director of education and interpretation for the National Park Service. She says in a time of budget cuts, the agency has to find ways to still meet its goals. And one of the most important services that the Park Service provides every day is nature interpretation. Question: You can probably read this text in the section of_.
