Article: On May 18,1969,NASA astronauts Thomas Stafford,John Young,and Eugene Cernan boarded the Apollo 10 lunar module --the fourth manned mission in the US Apollo Space program and only the second after Apollo 8 to circle the moon.Its mission was to circle the moon and thoroughly test the components and procedures to pave the way for the first lunar landing. The mission went perfectly without incident--at least that's what every one believed. However, that view has changed since February 22, after NASA released a digital recording of strange music heard by the space travelers.Then as they were re-entering the zone where they could communicate with ground control.One of the astronauts asked if they should report it.In response, Stafford expressed his doubts if anyone would even believe them.But they needn't have worried. When NASA experts listened to the recordings,they thought the strange sounds were radio interference. Michael Collins--the Apollo 11 pilot--said that the only reason why he was not shocked upon hearing them was that he had been forewarned by NASA officials.Collins also said that the music stopped as soon as the lunar module landed on the moon. So why did it take NASA over 40 years to release the digital recording of the awful music only after it was featured in a recent television series NASA's Unexplained Files? The US Space Agency says they have not been hiding them.In the press release that accompanies the release of the recording,NASA officials state,"The Apollo 10 audio clips were uploaded in 2012, but the mission's sound recordings have been available at the National Archives for anyone that wanted to hear them since the early 1970s." Eugene Cernan, Apollo 10's pilot who heard the sounds first,also released a statement saying,"I don't remember that incident excited me enough to take it seriously.It was probably just radio interference.Had we thought it was something other than that,we would have briefed everyone after the flight. We never gave it another thought." While most people are ready to... Question: According to the passage, _ . Options: A: the mission of Apollo 10 turned out to be unsuccessful B: NASA made the TV series to clarify some space-related mysteries C: Al Worden on Apollo 15 believes in aliens and logic D: Michael Collins knew about the strange sounds before his flight

Read the article and select the best answer. Article: Many artists late in the last century were in search of a means to express their individuality. Modern dance was one of the ways some of these people sought to free their creative spirit. The beginnings of modem dance were happening before Isadora Duncan, but she was the first person to bring the new dance to general audiences and see it accepted and acclaimed. Her search for a natural movement form sent her to nature. She believed movement should be as natural as the swaying of the trees and the rolling waves of the sea. Her great contributions are in three areas. First, she began the expansion of the kinds of movements that could be used in dance. Before Duncan danced, ballet was the only type of dance performed in concerts. In the ballet the feet and legs were emphasized, with virtuosity shown by complicated, codified positions and movements. Duncan performed dance by using all her body in the freest possible way. Her dance stemmed from her soul and spirit. She was one of the pioneers who broke tradition so others might be able to develop the art. Her second contribution lies in dance costumes . She discarded corset, ballet shoes, and stiff costumes. These were replaced with flowing clothes, bare feet, and unlimited hair. She believed in the natural body being allowed to move freely, and her dress displayed this ideal. Her third contribution was in the use of music. In her performances she used the symphonies of great masters, including Beethoven and Wagner, which was not the usual custom. She was as exciting and eccentric in her personal life as in her dance. Question: According to the passage, nature meant _ to Duncan. Options: A: something to conquer B: a model for movement C: a place to find peace D: a symbol of disorder

Q: Read the article and select the best answer. Article: The economy has developed a lot while the Internet is still not fully used in China. A study shows that about two-thirds of typical Chinese Internet users use the computer for news, often entertainment-related, or for online games, music or movies, all can be downloaded for free. Most prefers messages to e-mail, seldom makes online shopping at all. Although they are now depending on the Internet more often than before to communicate with others who have the same professions, hobbies and political interests, online shopping still remains unpopular in China. Three-quarters of users surveyed have never bought anything over the Internet, and only 10 percent do shopping even once a month. Among those who do buy online, most pay for entertainment while others buy phone cards, or computer hardware or software. "Many people don't trust the quality of goods bought online," the researcher said, "If they buy it in a store and don't like it, they can easily bring it back." The survey was done in Beijing, Shanghai, Guangzhou, Chengdu and Changsha. Results do not necessarily project countrywide because Internet use in the countryside is lower than in cities. The study showed that the typical netizens in the five cities are richer and more highly educated. Males make up two-thirds of the group, and more than 80 percent of users are under 24.Surprisingly, with the ages increase, the percentage decreases. China has more than 200 million people online, however, forty-two percent say they do not use search engines. Others seek entertainment news, as well as information useful for work or study on line. Baidu. com was used by half of those surveyed, compared with a quarter for Google, the leading search engine in the United States. Question: A typical Chinese Internet user will be the one who _ . Options: A: likes to send e-mails B: likes to buy goods online C: likes to pay for entertainment D: likes the games sites
A: D

Yet childhood bullying really can damage your long-term health. Gone are the days when bullying was considered an unavoidable and finally harmless part of growing up -- just last month we learned that childhood bullying can lead to poorer mental health even into middle age. Now William Copeland at Duke University in Durham, North Carolina, and his colleagues have shown that it can have lasting physiological effects too. They tracked 1,420 nine-year-olds right through their teens. Each child was seen up to nine times during the study and asked about bullying. The team then measured levels of C-reactive protein (CRP) in their blood. CRP is a marker of inflammation linked to higher risk of cardiovascular disease and problems like diabetes. "Because we were collecting biological samples throughout, we were able to look at CRP levels in subjects _ their bullying involvement." says Copeland. "This really gives us an idea of the changes bullying brings about." Although CRP levels naturally rise in everyone during adolescence, levels were highest in children who reported suffering from bullies. Even at the ages of 19 and 21, children who had once been bullied had CRP levels about 1.4 times higher than peers who were neither wrongdoers nor victims. In a cruel twist, the bullies had the lowest levels of all, suggesting they didn't suffer the same health risks. They may even see a benefit from their behavior, though Copeland stresses it doesn't defend their actions. "The goal would instead be to find other ways to produce this protective effect without it being at someone else's expense." he says. Andrea Danese at King's College London has before shown that ill-treatment during childhood can lead to high levels of inflammation in adult life. "This new study is a helpful addition in showing that these effects extend to another important childhood stressor." he says. He suggests that care workers monitor levels of CRP in children...
