You may already know that more than a million years ago, glaciers, or vast blankets of moving ice, covered one third of the earth. You also may know tens of thousands of years ago, the glaciers started to melt, retreating to their current position in the Antarctic and Greenland. You may even know that glaciers also exist in all the world's great mountain regions. But do you know that glaciers cover about 6 billion square miles of the earth and store about 75 percent of the earth's fresh water.
A glacier forms in a cold climate when a winters snow does not completely melt during the following summer. Snow continues to accumulate and partially melt year after year. As the accumulated snow becomes heavier, the lower layers crushes under the weight and changes into ice. Over time, the mass of ice thickens and moves. The ice is either pulled slowly downhill by gravity - as in the valley glaciers found in the Alps, on the Alaskan coast, and in the Western United States - or forced outward in all directions by its own weight - as in the ice sheets and icecaps covering most of Greenland and Antarctic a. During the glaciations (冰川作用),a glacier moves ( usually about 3 feet per day). It picks up pieces of rock that cut and polish the land and carve out steep-side valleys . During deglaciation (冰消作用),a glacier withdraws and often leaves large deposits of sand and stones. The process of glaciation and deglaciation formed the Great Lakes in North American during the Ice Ages.
Some scientists believe that ice ages similar to those of the past will occur, but they disagree on when this will happen. Other scientists think that global wanning will occur instead, melting the glaciers and flooding areas as sea levels rise. No one knows for certain which event will occur, but neither predicts well for mankind.

3.What is the attitude of the writer towards the argument between scientists in the last paragraph?

British scientists seeking to protect the environment have designed a biodegradable mobile phone cover that breaks down in soil when discarded and sprouts (发芽)a flower from a seed put inside the case. Researchers at the University of Warwick in central England said the novel device, made from a specially designed polymer (聚合材料),is a blessing for the environmentalists.
Millions of mobile phones are thrown away every year as the industry produces large quantities of new models without caring about the quality. “It is really original in the phone industry and consumers are happy because they feel they are doing something for the local environment,” said Keny Kirwan from the university of Warwick. Designers have made the hesitant users feel sure that the seed, put into a transparent window, only sprouts when the phone cover is discarded. “We put sunflower seeds into the covers of the samples, but we are working with gardening researchers to identify which other flowers would perform best. Maybe we could put poppies (虞美人)or roses next time,” said Kirwan.
1.Why is the new mobile phone unique?
A.It is popular with young people.
B.It is environmentally friendly.
C.The user can make it flower whenever he or she likes.
D.Its colour is beautiful.
2.What does the underlined word “ discarded” mean?
A.Thrown away. B.Updated. C.Cleaned. D.Replaced.
3.What can be a suitable title for the text?
A.Good News for Environmentalists B.Promising Mobile Phone
C.Changing Wastes into Valuables D.Flowering Mobile Phone
4.In which section of a magazine may this text appear?
A.Entertainment. B.Science and technology.
C.Education. D.Health.
I shall always recall the autumn and the girl playing the violin. She made me realize true friendship. I know she will always be my best friend .
It was a golden season. I could see the yellow leaves falling on the cool wind. In such a season, I liked walking alone on the leaves in the woods, listening to the sound of them.
Autumn is a lonely season and everything is still. Such surroundings always get me down. But one day, the sound of a violin flowed into my ears like a stream flowing in the mountains. I was so surprised that I jumped to see what it was. A young girl, standing in the wind, was lost in playing her violin.
I had never seen her before. The music was so nice that I listened quietly. Lost in the music, I didn't know that I had been standing there for so long but my existence did not seem to disturb her.
Leaves were still falling. Every day she played the violin at the same time and the same place and I went to watch her performance . I was the only listener. The autumn seemed no longer lonely and life became interesting. Though we didn't know each other, I thought we were already good friends. I believe she also had the same feeling.
Autumn was nearly over. One day, when I was listening carefully, the sound suddenly stopped. To my astonishment, the girl came over to me.
“You must like the violin.” she said.
“Yes, and you play very well. Why did you stop?” I asked.
Suddenly, a sad expression appeared on her face and I could feel something unusual.
“I came here to see my grandmother, but now I must leave. I once played badly. It was your appreciation and listening every day that encouraged me.” she said.
“In fact, it was your playing that gave me a meaningful autumn,” I answered, “let's be friends. The girl smiled and so did I.
During the rest days left, I had never heard her play again. Only thick leaves were left on the ground. But I will not forget the girl. She is just like a dream, so short, so bright, like a shooting star giving off all its light that it makes the autumn sky shining.
