[EX Q]: Article: A new study has been carried to test the role of story telling in lowering blood pressure. Dr. Thomas Houston, a professor of the University of Massachusetts Medical School, led a group of scientists that investigated how pre-recorded videos of hypertension patients' talking about their medical histories helped another group of patients with high blood pressure to control their condition over several months. Houston was surprised by their studies that suggested that communication can be a powerful tool in medicine. They showed that those who had had similar experiences, when talking to someone with a similar background, could help change their behavior to become healthier. Hypertension is difficult to control, since it is dependent on diet, exercise and mental state. Medical treatments with drugs, and lifestyle therapies have been ly ineffective because people find it hard to follow those medical requirements. In the test, his team carefully chose their story-tellers from 230 members of a patients' community with whom they could most easily relate. Next, they divided their study population into two groups. One received three interactive DVDs containing the tellers' stories of their experiences in living with and treating their hypertension. The other were given educational discs on an unrelated health topic. The study volunteers reported that they had listened to the DVDs, and after three months, those who heard the stories of the hypertensive patients lowered their blood pressure. While the study did not _ how the story-telling influenced the patients' behavior, Houston suspects that watching patients of similar backgrounds who had a similar medical experience helped to motivate them to seek medical help to their hypertension. They found that after six months the difference in blood pressure between those who watched the story-tellers and those who observed the unrelated videos remained, suggesting that the story-telling continued to have an effect.

[EX Q]: Article: Friendlies abandoned as name for mascots The name "Friendlies" has been abandoned as the organization committee for the 2008 Beijing Olympics silently changed the English name of the Games' five mascot dolls last week. The organization committee decided to adopt the name "Fuwa", which is a pinyin translation of its Chinese name and is more frequently used in prefix = st1 /China. However, the organization committee replaced all Friendlies to Fuwa on its official site, but without giving a formal announcement to inform the public of the change. It is said that they received an inside notice about the change last week but don't want to emphasize it for fear of affecting the sales of Olympic goods. Li Yanjun, a Legal Affairs Department official, said the decision was made considering a variety of reasons but did not want to comment on them. "You may know about the background and many unfavorable comments concerning the mascots' former name across the web, but I won't comment on them," Li said. "I'm not in the position to make it clear if the change was caused by this." A report published last week on China Radio International (CRI)made the name change known and listed the reasons why the Friendlies name should be changed. "Firstly, Friendly is somewhat an unclear name, which could refer both to friendly people and friendly matches,"a Dr. Li from LanzhouUniversitywas quoted as saying on the site. "Secondly, the term Friendlies has a similar pronunciation to 'friendless' and thirdly, the spelling of Friendlies could be split as 'friend lies'." Laura Fitch, a Canadian who works in Chinaas news editor, welcomed the change, saying the name Friendlies sounds a "a little bit childish" and "doesn't really have a meaning."
Question: why did the organization committee change the name "Friendlies" into "Fuwa" without giving a formal announcement?
Options: (A) Because it is not important to make it known. (B) Because everybody will know it by surfing the internet. (C) Because it will perhaps affect the sales of Olympic products. (D) Because all the people will criticize them for changing its name.

[EX Q]: 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.
