Article: The Internet brings us many advantages. With the Internet, people can send and receive emails. On the Internet, people can skim over news. Using the Telnet, the user anywhere on the Internet can log into any other machine on which he has an account. It is possible to use the FTP program to copy files from one machine on the Internet to another. But the Internet also brings us troubles. Internet use seems to cause a fall in psychological health, according to research at Carnegie Mellon University. Even people who spent just a few hours a week on the Internet experienced more depression and loneliness than those who logged on less often, the twoyear study showed. And it wasn't that people who were already feeling bad spent more time on the Internet, but that using the Net actually seemed to cause the bad feelings. Researchers are puzzled over the results, which were completely opposite to what they had expected. They expected that the Net would prove socially healthier than television, since the Net allows users to choose their information and to communicate with others.The fact that Internet use reduces time used for family and friends may be the reason for the drop in health, researchers said. Faceless, bodiless"virtual" communication may be less psychologically satisfying than actual conversations, and the relationships formed through it may not be so deep. Another possibility is that exposure to the wider world through the Net makes users less satisfied with their lives. "But _ it's _ important _ to _ remember _ this _ is _ not _ about _ the _ technology; _ it's _ about _ how _ it _ is _ used,"said one of the researchers. "It really points to the need for considering social factors when you design new inventions." Question: According to the passage, which of the following is TRUE? Yes or no, is the answer "The twoyear study showed that using the Net seemed to cause the bad feelings."?
No

Article: Local officials in Beijing promised to furtherprotect the city's cultural heritage , in particular the narrow streets known as Hutong. Hutong are commonly found in the cities of North China, but they are at risk. Beijingis currently believed to have fewer than 1,000 Hutong, most of which are nearthe Forbidden City. Only 60 years ago, thenumber was 3,250. In the old districts of Dongcheng and Xicheng, which cover 62square kilometers, some people will be asked to move from Hutong houses toavoid further damage to the ancient architecture. "On average more than 100,000 people visit the Forbidden City during the National Day holidays. Thevisits put pressure on the protection of cultural relics," said Huang Yan,director of the Beijing Municipal Commission of Urban Planning, adding that Hutongshould be protected from human damage. The government focused on how the protection planswere carried out and how the management of cultural heritages worked. WangShaofeng, head of the Xicheng district government, said the area has 182cultural relics, many of which were built as far back as the Yuan Dynasty(1271-1368). The district of Xicheng has 1.28 million residents in its 57square kilometers of land. "The most efficient way is to decrease the localpopulation to reduce the possibility of causing harm to the heritage," Wangsaid. "Each community has been required to report thestatus of its cultural heritage, especially Hutong, and any actions to damagethe heritage will be punished," Wang said. No one knows for sure how many Hutong will be leftin the coming 100 years. Question: How many hutong have disappeared in the pastsixty years in Beijing? Yes or no, is the answer "About 2000."?
Yes

Article: An incredible dog has mastered more than just the doggy paddle -- the golden brown pet helps disabled children learn how to surf. Ricochet's owner Judy Fridono said, "I was working with her at balance and coordination . Her balance is so good that she can help to stabilize the board for the kids. And it makes them feel good to know that Ricochet is there with them, keeping them company." After becoming an expert, two-year-old Ricochet helps the disabled children build up the confidence to get on the board themselves. Dressed in a yellow jacket, Ricochet helps to counter-balance the board and acts as a reassuring presence. Ms. Fridono knows what an impact her beloved dog can have. She herself was severely disabled since her teens. Having Ricochet around lifts her spirits, and inspires her to conquer her pain to get on the board. "Ricochet has taught me to focus on what I can do, rather than what I can't," she said. One of those who have benefited from Ricochet's skills is six-year-old Ian McFarland. In 2008 a car crash left him with brain damage. Although he had loved surfing before the accident, he was too nervous to go back into the water. His fear turned to excitement, when he was told he could try a tandem surf session with Ricochet. Their session was a success and by the end of it, Ian was smiling from ear to ear. As well as helping with treatments, Ricochet also raised PS5,000 to help continue Ian's recovery. Over the last 10 months, Ricochet's excellent performances on the sea have raised more than PS30,000 for a number of charity causes. Question: What role does Ricochet play according to the passage? Yes or no, is the answer "She helps the disabled children learn to surf."?
Yes

Article: Imagine what you could do with a machine that could make things disappear. For inspiration, you could read some books. In the books of J.R.R. Tolkein, Bilbo Baggins finds a ring that can make him disappear. Of course, there's also poor Harry Potter, who used his invisibility cloak to hide from danger. Now that you've got some ideas, it's time for the hard part: building the cloak. To do that, you have to give up science fiction and turn to real science. An invisibility cloak has to cheat anything or anyone who might be watching. In order to understand how something can be seen, it's important to understand how we see. Human beings can only see objects that reflect light waves. These waves enter the eye and are then processed by the brain. However, if an object doesn't reflect light, then the waves don't enter the eye, and the brain doesn't process. So building an invisibility cloak is building something that doesn't reflect light. Cummer was part of a team of scientists from Duke University, including David Smith and David Schurig, who built the world's first version of an invisibility cloak. They had been inspired by the work of a British physicist, John Pendry. He in May said that an invisibility cloak was possible and Pendry was not the only one thinking about a disappearing act. At the same time, a Scottish physicist, UIf Leonhardt published a paper on building invisibility equipment. "It wasn't easy," says Cummer. "As often happens in science and research, it didn't work very well the first time. That first cloak didn't work like Harry Potter's --- the scientists didn't actually see anything disappear. So the research is still under way. " Question: Cummer and other scientists got the idea of building an invisibility cloak from _ . Yes or no, is the answer "the work of a British physicist"?
Yes
