Edmund Halley was an English scientist who lived over 200years ago. He studied the observations of comets which other scientists had made. The orbit of one particular comet was a very difficult mathematical problem. He could not figure it out. Neither could other scientists who dealt with such problems. However, Halley had a friend named Isaac Newton. Who was a brilliant mathematician. Newton thought he had already which he had done it. He told Halley that the orbit of a comet had the shape of an ellipse. Now Halley set to work. He figured out the orbits of some of the comets that had been observed by scientist. He made a surprising discovery. The comets that had appeared in the years 1531, 1607 and 1682 all had the same orbit. Yet their appearances had been 75 to 76 years apart. This seemed very strange to Halley. Three different comets followed the same orbit. The more Halley thought about it, the more he thought that there had not been three different comets, as people thought. He decided that they had simply seen the same comet three times. The comet had gone away and had come back again. It was an astonishing idea! Halley felt certain enough to make a prediction of what would happen in the future. He decided that this comet would appear in the year 1758. There were 53 years to go before Halley's prediction could be tested. In 1758 the comet appeared in the sky. Halley did not see it, for he had died some years before. Ever since then that comet been called Halley's comet, in his honor. Halley made a surprising but correct prediction in the year _ . A) 1704 B) 1705 C) 1706 D) 1707

Well, it's time for Words and Their Stories. We present more expressions about food from Elenir Scardueli, a listener in Brazil. My mother believes you are what you eat. Then she'd always give us nutritious food. She likes serving us meat and potatoes, which can also mean the most important part of something. Here's another expression about meat: one man's meat is another man's poison--one might like something very much while another person might hate it. My father's a good and honest person. People say he's the salt of the earth. He'd never pour salt on a wound, or make someone feel worse about something. However, sometimes he tells us a story that seems bigger than life. So we have to take it with a grain of salt. My husband makes enough money to support our family. So we say he brings home the bacon. He can cut the mustard, or do what is expected of him at work. Besides, he stands almost two meters tall, so it's easy to find my husband in a crowd. He is a tall drink of water. I take the train to work. It is not a pleasant ride because the train is so crowded that we are packed like sardines. When we fail to see problems at work, my boss tells us to wake up and smell the coffee. We need to pay more attention and fix the problem. I once made a big mistake at the office and felt foolish. I had egg on my face. Over the weekend, my friend invited me to watch a football game on television. But I do not like football. It is not my cup of tea. We hope this has given you food for thought and stay with us next time. Thank you. The phrase "you are what you eat" suggests that _ . A) eating plays an important part B) meat and potatoes are basics C) rich nutrition holds the key of a meal D) a good diet is important for good health

Ques: The debate over children from other European countries in prefix = st1 /Britain's school was refried after the country's leading teachers told The Observer that rising numbers of foreign pupils are putting some of schools near the breaking point. Members of the National Association of Head Teachers will this week tell the government that the problem is starting to change the culture of some schools. Some heads said the situation was out of control. Though head teachers think the new pupils have great ability and they should be welcomed into schools, they are worried that they don't have enough money to deal with the situation. "There is a feeling among some of our members that this is out of control and no one knows the final solution," said Mick Brookes, general secretary of the NAHT. Brookes who will give evidence this week to the government added, "some schools just don't know how many immigrant children they will have to admit." He said that while schools could take in one or two foreign pupils, some were struggling with the sudden large increase in the number of children overseas. Clarissa Williams, head of Tolworth Girls School in Kingston upon Thames, south London, said she received &1,300 a year from the government to cover the costs of teaching English to foreign pupils but was having to spend &30,000 of her own budget to keep pace. On Tuesday, the association will tell the House of Lords that education budgets have not kept pace with the increase in the number of pupils for whom English is a second language, or not spoken at all, who have entered Britain since the European Union expanded From the passage we know that_. A) pupils from other countries can not speak English B) many schools have already reached the breaking points C) British schools have profited from the expansion of the European Union D) the expansion of the European Union has brought many foreign students to Britain

Ques:Earlier this month, two rock climbers achieved what many thought impossible: They climbed up the 3,000-foot-high Dawn Wall in Yosemite National Park without specialized equipment. Climbing without this equipment is called"free-climbing."Until now, no one had free-climbed to the top of the rock face, which is a part of the mountain EI Capitan. El Capitan, which means"the captain"or"the chief"in Spanish, has always presented a challenge to climbers. But the Dawn Wall, on the mountain's southeast face, is a particularly difficult route to the summit . It is a rock formation that is both steep and relatively smooth. This makes free-climbing the rock face seem almost impossible. About seven years ago, professional climber Tommy Caldwell spotted a possible route up the wall. It took years of planning and preparation, but this month, Caldwell, 36, and his friend Kevin Jorgeson, 30, finally make the climb. Free climbers do use ropes and other basic safety equipment to catch them if they fall -- and Caldwell and Jorgeson fell often. Before starting their climb, they broke down their route into 32 sections. Each section was based on a rope length called a"pitch."The rope was secured into the rock face to catch the climbers if they fell. Caldwell and Jorgeson's goal was to climb the Dawn Wall without returning to the ground. If they fell, they had to start that pitch all over again. The two men started climbing on December 27. They slept in hanging tents, and a team of friends brought them food each day. The men had spent years rehearsing the movements it would take to get through each pitch. They made it through the fist half of the climb relatively easily. But halfway up, Jorgeson ran into trouble. In one difficult spot, he fell each time he attempted to climb. After 10 days of trying, Jorgeson finally made it to the next pitch. Getting through that troublesome pitch gave both climbers renewed energy. They finished the rest of the climb five days later, on January 14. To climb Yosemite's Dawn Wall, Caldwell and Jorgeson _ . A) received one year 's training B) chose the nearest route C) made thoughtful preparations D) used special equipment
