PROBLEM: Article: Mary went out at night. She never forgot the night when she met a robber many years ago. That evening, she was invited to a birthday party which lasted until two o'clock in the morning. Without company Mary walked along the quiet street. Suddenly from the shadow of a dark building a tall man with a sharp knife in his right hand ran out at her. "Good evening, lady," the man said in a low voice, "I don't think you wish to die here." "What do you want?" Mary asked. "Your earrings .Take them off!" Slowly Mary's eyes looked down. She tried to cover her necklace with the collar of her overcoat while she used the other hand to take off both of her earrings, and then she quickly threw them on the ground. "Take them and let me go." she said. The robber looked at her only feeling uncertain. He saw the girl didn't care for the earrings at all, only trying to protect the necklace. He realized the necklace would cost more. So he said, "Give me your necklace." "Oh, sir. It's not worth much. Please let me keep it." "Stop rubbish. Quick!" With shaky hands, Mary took off her necklace. As soon as the robber disappeared, she picked up her earrings and ran as fast as she could to one of her friends. The earrings cost 480 pounds and the necklace the robber had taken away cost only six pounds ten shillings.

PROBLEM: Article: It is a reply to a letter written by Zhai Mingjun, a 16-year-old girl in the class. The two astronauts thank the student for her concerns and wish the class luck in their future studies. "I' m so happy that the two space men replied with a few encouraging words," said Zhai. Her letter was one of the 10 winning letters taken into space by Fei and Nie, who have succeeded in traveling space in the Sixth Shenzhou Spaceship. Zhai wrote the letter as if she were a younger sister of the astronauts. "As the single child in my family, I always hoped that I would have an elder brother that I could be proud of," Zhai said. "I thought that the astronauts would be lonely during such a long space trip. I hoped they would feel happy and warm when reading my letter." Many of Zhai' s classmates also wrote their words of encouragement and admiration to the astronauts. "The letter to the astronauts made us believe that we can also be part of the manned space programme," said Zhao Dongxu. All the students have high expectations for China' s future space programme. "I heard that Snoopy is the mascot for US astronauts. I hope I can design a mascot for our heroes," said Liu Mengjie, 16. "A physics class taught by astronauts in outer space would be very interesting. I want to be the astronaut who teaches students about zero gravity with my head upside down in the spaceship," said Han Yinan. Many students think that the manned space program is still far away from them. But they feel proud that ordinary students could participate in such a great scientific achievement and hope there will be more possibilities to take part.

PROBLEM: Article: A dentist's office may not be everyone's idea of a perfect holiday destination.But a growing number of Europeans are travelling abroad for medical treatment to save money,or maybe to combine a visit to the doctor with some sightseeing,creating a potential but fastgrowing market for traditional tour operators. "It was simply cheaper for me to go to a dentist in Hungary," said a 42yearold physical therapist from Berlin.He chose the clinic near Budapest from an Internet advertisement,attracted by hundreds of euros in savings compared with the same treatment in Germany.He was happy to find when he got there that the clinic was clean,the staff qualified and the work thorough. People travel abroad for medical treatment for various reasons:it's cheaper,they face a long wait at home,or the treatment they want is not available in their own country.The Britishbased Medical Tourist Company refers about 100 patients a year to hospitals in India for treatments.And Chief Executive Premhar Shah reports rapid growth in demand from customers in Africa,where it can be harder to find wellequipped medical facilities for complex surgeries. Some patients who have immigrated may prefer to return to be close to their families when they undergo surgery."People will want to take the opportunity to seek treatment in places where they have relatives who might be able to look after them.I'm seeing that especially with younger people from eastern Europe," said a professor at the University of Oxford. For some,there is the attraction of free treatment abroad.British lawmakers have called for tighter checks on patients arriving for treatment,out of concerns that foreign citizens are travelling to Britain to take advantage of the free service. The global medical tourism market is believed to be worth $40 billion to $60 billion and growing at about 20 percent per year.
