Article: For every woman who feels like she's had to scale back her personal ambitions since becoming a mother, gold medal cyclist Kristin Armstrong has a message: Don't give up on your dreams. She retired after winning gold in Beijing to start a family; son Lucas arrived in 2010, but then she decided to compete again in the London Olympics. She won a gold medal at last. The decision to start training again wasn't easy. "I struggled with that a lot," she told a newspaper. "At the beginning I felt selfish, I felt like, 'Well, I'm not supposed to be thinking of myself anymore. It's all supposed to be for my kid.'" She faced physical challenges of getting back into competition shape after giving birth, as well. When she started racing in the spring of 2011, she was still breast-feeding; she would nurse her son, then race, then breast-feed again after the race. Her days revolved around Lucas and training. "I feel like I'm able to do what I love to do and still manage a family and have that balance," Armstrong said. "That you have a family or a child doesn't mean that you have to stop going after what you dream of individually." Armstrong makes balance look easy, whether it's on her bike or as an athlete-mom. But she points out that you can't have it all without making some sacrifices. For example, don't expect a neat home--her husband, Joe Savola, who she describes as her support system and her "protector", says he's had to give up on trying to keep everything orderly at home and just accept that their living room has become Lucas's playroom. For Armstrong, she's sacrificed time with friends who had kids around the same age--there just wasn't time. Now, she says, "That sounds like fun to me." As she heads home to Boise, Idaho, she's ready to do regular mom stuff. Question: In most days of 2011, Armstrong could be described as   _  . - a housewife and a new mom - an athlete and a career woman - a parent and a sportswoman - a wife and a good mother
a parent and a sportswoman

Read the following article and select the best answer. Article: Art robbery and art forgery   are both major themes in crime movies and literature.In the 2012 comedy movie Gambit, British actor Colin Firth plays an art curator who cheats his abusive boss into buying a fake Monet. In reality, art crimes are no less interesting and exciting. According to The New York Times, over the past 15 years, Glafira Rosales fooled two local commercial art galleries into buying 63 false works of art for more than $30 million.She passed off fake paintings as works by 20th century modernist masters such as American artists Mark Rothko and Jackson Pollock.But in fact, these so called "newly discovered works" were all produced by a single man, a Chinese immigrant named Qian Peishen. The art world was shocked by Rosales' deception.But to the public, it was amusing and most satisfying to see wealthy people get tricked. So what decides the value of a piece of art? Is it beauty? Is it the artist's talent and craftsmanship? Or is it just because the artist is famous? We should take beauty out. If the buyers were buying paintings only for their beauty, they'll be content displaying good fakes on their walls. They wouldn't be so upset when a forgery is exposed. The art market claims that great artists are inimitable, and that this inimitability justifies the absurd price of their works. We can't deny that most famous artists are good at what they do, but forgers like Qian show that their works are imitable.Otherwise, the difference between the original and the copycats would be obvious and Rosales would not be able to fool anyone. According to an article in the Economist, expensive paintings are what economists call positional goods. They are valuable because other people can't have them. With other goods, a higher price reduces demand.But art turns down the laws of economics. "When the goods that is really being purchased is evidence that the buyer has paid a lot, price increases cause demand to boom," explained the article. That's why scarcity and authenticity are so important in the art... Question: What is the law of economics theory behind art goods according to the economists? - They are valuable goods. - High prices reduce the demand of art goods. - High prices increase the demand of art goods. - They are produced in quantities to satisfy people.
High prices increase the demand of art goods.

Article: LONDON, Feb. 18,2014 (Xinhua News agency) --Britain will send experts to East China's Shanghai to learn from the city's experience in maths teaching in an attempt to raise the teaching standards. British Education Minister Elizabeth Truss is to lead a delegation of experts on a fact-finding mission to Shanghai's schools next week to see how children there have become the best in the world at maths, to get a first-hand look at maths classes and teaching methods there, and particularly to investigate why the performance of almost all children in Shanghai is high, regardless of gender or income. Britain was last year placed 50th out of 148 countries and regions in the World Economic Forum's competitiveness ranking in quality of maths and science education. Two years ago, Shanghai topped the 2012 international PISA tables for maths, while England was ranked in 26th place. The top five were all in Southeast Asia, with 15-year-olds in Shanghai judged to be three years ahead of their peers in maths. The education department said: "England's performance in maths has lagged behind while other countries have improved and overtaken us, including Poland and Germany." Actually, it is the latest step in the government's drive to raise standards in maths, looking at what has made schools in the far East the most successful in the world in teaching the subject. "Shanghai is the top-performing part of the world for maths--their children are streets ahead. Shanghai and Singapore have teaching practices and a positive mind that make the difference. They have a belief that diligence makes up for lack of ability," Truss said. "Our new curriculum has borrowed from theirs because we know it works--early learning of key arithmetic, and a focus on times tables and long division , for instance." She was determined to change the situation as performance in maths is weakening the country's skills base and threatening the productivity and growth. The government is emphasizing maths because of the importance of good grades in the subject... Question: What can we infer from the news? - The students in Britain don't work hard at Maths. - The students in shanghai are the smartest in the world. - The education of science in Britain is no better than that of maths. - Most British citizens are dissatisfied with teachers' work.
