Q: Read the article and select the best answer. Article: Some Chinese new-rich like eating shark fin soup because they think it shows their class. However, for the Chinese NBA idol Yao Ming, doing so is unacceptable as the practice has led to the overfishing of sharks. When Yao and his wife Ye Li got married in 2007, they publicly announced that they would not allow shark fin soup to be served at their wedding banquet. Actually, Yao had been saying no to shark fins since 2006, when he was appointed as the Goodwill Ambassador for wild life protection. Now, the 226-cm big guy is resorting to his personal influence to encourage more to say no to eating the soup and to raise awareness of animal protection. "Sharks are friends of human beings. They are not our food," Yao said. Other celebrity athletes like Olympic champions Li Ning and Kong Linghui are following on the heels of Yao, throwing themselves into serving the public as Goodwill Ambassadors for wild animal rescue. Recent reports about Yao's retirement have saddened tens of thousands of basketball fans both at home and abroad. Yet Yao's influence goes far beyond the basketball courts. Yao has engaged himself in charity and public welfare services for quite a while. When the devastating 8.0-magnitude earthquake hit Wenchuan in southwest China in 2008, Yao donated 2 million yuan . "When I was a little boy, my parents and teachers told me to help others and to be a good man," Yao recalled. "But I could not donate then because I had not much pocket money. After I moved to Houston, I got involved in quite a number of community service activities and I felt a strong sense of achievement when I got people together," Yao said. Like Yao, newly crowned French Open champion Li Na has showed her willingness to donate. Li gave 480,000 yuan of her prize money from the open, plus 20,000 yuan from her own pocket, to a local nursing home in her hometown. Another Chinese sports icon, hurdler Liu Xiang, has also been actively involved in charity for years. Question: The reason why some Chinese new-rich like eating shark fin soup is that they think _ . Options: A: it is very delicious B: it is very cheap and healthy C: it is very popular in society D: it can show their status
A: D

Q: Read the article and select the best answer. Article: A euphemism (from the Greek words eu--well and pheme--speak) is a word or expression that is used when people want to find a polite or less direct way of talking about difficult or embarrassing topics like death or the bodily functions.Most people,for example,would find it very difficult to say in plain language that they have arranged for their sick old dog to be killed.They would soften the pain by saying:We had Ruby put down or We had Ruby put to sleep.Many people prefer to call someone plain than ugly,or cuddly rather than fat. Euphemisms are an important part of every language,but it seems that English has an evergrowing number of them.The nonnative speaker not only has to make sense of the euphemisms he hears,he also has to learn which euphemisms are appropriate in any particular situation.He might be aware that his American friend needs to use the toilet when she asks where the bathroom (or restroom,or comfort station) is,but he is less likely to guess that his English friend has the same need when he says he has to see a man about a dog.He might have learned,for example,that in the family way is a euphemism for pregnant.If,however,he says to his boss,"Congratulations!I hear your wife is in the family way," he would be using an expression that is too familiar for the circumstances. Schools are full of euphemisms.At Frankfurt International School,for example,the special lessons given to students who are having difficulties in their school subjects are called Study Center (in the middle school) and Academic Workshop (in the high school).Teachers rightly do not want to upset students or parents by being too frank or straightforward,and usually choose a softer word or expression to convey the same message. Question: According to the passage,people use euphemisms in order to _ . Options: A: make themselves understood B: avoid embarrassment C: to sound straightforward D: attract attention
A: B

Q: Read the article and select the best answer. Article: Scientists have found what look like caves on Mars , and say they could be protecting life from the planet's terrible environment. The first caves discovered beyond the Earth appear as seven mysterious black dots on the pictures sent back by NASA's Mars Odyssey orbiter. Each as large as a football field, they may be openings into natural caves below the Martian surface. "If there is life on Mars, there is a good chance you'd find it in caves," said Jut Wynne, one of the researchers who noticed the features while working on a US Geological Survey Mars Cave Detection Program. Jonathan Clarke, a geologist with the Mars Society of Australia, yesterday described the discovery as exciting. One photo taken at night by an infrared imager showed one hole to be unusually warm, suggesting hot air trapped during the day is flowing out. "I said: 'Wow, that's a cave'" Dr. Clarke said excitedly. "People have been looking for these for a long time; now we have found them." He agreed such caves would be perfect places to hunt for life escaping from the bitterly cold, radiation-soaked , dry surface. "Tiny drops of water could collect inside," he said. "If there are gases coming out, they could provide energy for a whole range of bacteria. A cave is also a protection from radiation; the surface of Mars is exposed to high levels of space radiation." The caves probably formed when tube-shaped lave flows spread across the planet long ago. The outside of the tubes cooled, forming solid walls, while something hotter inside allowed the remaining have to flow out, forming caves. Question: Necessary conditions for life on Mars mentioned in the passage may include_. Options: A: lava and energy B: water and radiation from space C: gases and lava D: water and protection from radiation
A: D
