The men, ranging from 19 to 63 years old, have been buried alive since a cave in the copper and gold mine where they were working fell down on August 5. It is the longest time anyone has ever survived being trapped underground.After the fall, the men found an emergency shelter off one of the mine's tunnels. The temperature in the dark shelter was around 90 F. For more than two weeks, the miners' water came from the radiator tanks on their work vehicles. They shared a supply of food that was meant to last for only 48 hours.The miners were totally separated until rescue teams made contact with the men on August 22. They sent a note to the surface explaining their situation. Rescuers drilled small holes to reach the cavern and sent down supply tubes containing food, water, clothes, medicine, fresh air and other supplies. They also received letters from their families, a television set and games.Additional falls slowed down rescue efforts. Finally, a tunnel was built that could fit a 13-foot rescue capsule, called the Phoenix. The escape hole measures 28 inches across, a tight fit for the winding 20-minute, 2,041-foot ride. The first miner reached the surface just after midnight on Wednesday. More than half of the men had been brought to safety by Wednesday afternoon.The miners were met by family members who were waiting at Camp Hope, a settlement of tents near the mine. Chile's president, Sebastian Pinera, cheered at the scene and hugged the miners. "We made a promise never to surrender, and we kept it," he said. After an immediate medical exam, the men were air-lifted to the nearest hospital for 48 hours of observation.1. The first paragraph tells us that trapped miners ________.A. shouted in joy after getting rescuedB. were buried while having a restC. came to the ground togetherD. were all different in ages2. What do we know about the emergency shelter?A. It was very hot inside.B. It had food supply for 48 workers.C. It had water stored for two days.D. It had a hole to get fresh air.3. What made the rescue more difficult?A. Miners got weak without food.B. Additional collapse happened later.C. The escape hole was too narrow to use.D. The rock was too hard to dig a tunnel.4. The underlined word "surrender" in the last paragraph may mean "________".A. dig outB. cheer up eC. give inD. take a chance三、语法填空An earthquake is a shaking of the ground ①________ (cause) by the sudden breaking and shifting of large sections of Earth's rocky outer shell.

Carnegie Hall is known not just for its beauty and history, but also for its amazing sound. It has been said that the hall itself is an instrument. It takes the music and makes it larger than life.Carnegie Hall is named after Andrew Carnegie, who paid for its construction. Construction on Carnegie Hall began in 1890 and the official opening night was on May 5, 1891.The hall was owned by the Carnegie family until 1924 when it was sold to Robert E·Simon. The building became very oldand in 1960, the new owner made plans to destroy it and build an office block. Isaac Stern led a group of people who fought to save Carnegie Hall and finally, the city of New York bought it for $5 million. It was then fixed up between 1983 and 1995.Advertisements and stories in newspapers about how Carnegie Hall needed help to recover its history led people to send in old concert programmes and information from all over the world. Over 12, 000 concert programmes were received and with these it was possible to make a proper record of Carnegie Hall’s concert history.Carnegie Hall is actually made up of several different halls, but the Main Hall, now called the Isaac Stern Hall, is the most famous. The hall itself can hold an audience of 2, 804 in five levels of seating.Because the best and most famous musicians of all time have played at Carnegie Hall, it is the dream of most musicians who want to be great to play there. This has led to a very old joke which is now part of Carnegie Hall’s history. Question: “How do I get to Carnegie Hall?” Answer: “Practise, practise, practise. ”1. It can be inferred that people wanted to save Carnegie Hall mainly because _______.A. it made a lot of moneyB. it was worth visitingC. many important concerts were held in itD. it made some musicians become famous2. How did Carnegie Hall recover its concert history?A. Through newspaper reports.B. Through old concert programmes.C. Through old photographs.D. Through old jokes.3. How long did it take Carnegie Hall to be fixed up?A. 9 years.B. 10 years.C. 11 years.D. 12 years.4. Which of the following would be the best title for the text?A. The History of Carnegie HallB. The Best Musician Having Played in Carnegie HallC. A Joke about Carnegie HallD. The Dream of Most Musicians三、读后续写When the boys and girls got on the bus early in the morning, they noticed Vingo, who sat in front of them, staring at a photo, completely in silence. At noon, the bus pulled into Howard Johnson ’s, a service area, and everybody got off the bus except Vingo. The youngsters began to wonder about him. When they came back, one of the girls sat beside him and introduced herself.“Want some drink? ” she asked.Vingo smiled and thanked her and became silent again.Late in the afternoon, they stopped at another HowardJohnson ’s, and this time Vingo went out. The girl insisted that he join them. He followed them to a restaurant and ordered a cup of black coffee and some cookies. When they returned, the girl sat with Vingo again. After a while, slowly and painfully, he began his story and told her that he had been in prison for the past four years, and now he was going home.“Are you married? ” asked the girl.“I don ’t know, ” he said softly.“You don ’t know? ”“Well, when I was in prison I wrote to my wife, ” he said, “I told her that I was going to be away for a long time, and that if she couldn ’t stand it, if the kids kept asking questions, and if it hurt her too much, she could just forget me. I ’d understand. I told her she didn ’t have to write to me. And she didn ’t. Not for three and a half years. ”“And you ’re going home now, not knowing? ”“Yeah. Well, last week, I wrote to her again. We used to live in Brunswick and there ’s a big oak (橡树) tree just as you come into town. I told her that if she didn ’t have a new man and if she ’d take me back, she should put a yellow handkerchief on the tree and I ’d get off and come home. If she didn ’t want me, forget it—no handkerchief and I ’d go on through. ”“Wow, ” the girl burst out, “Wow! ”She told the other youngsters, and soon all of them werein it.注意: 续写词数应为150左右。
