Q: Read the following article and select the best answer. Article: Some weight-loss camps, which are rare in China just a few years ago, have sprouted in Beijing, Qingdao, Shenzhen, and other cities. Today about 15 percent of adults, or 200 million Chinese, are reportedly overweight. Of these, 90 million--about 7 percent--are obese . Experts say the obesity epidemic is spreading to children, though more slowly than in adults. The trend, they say, will have a huge impact on the health of China's citizens and economy. "We're seeing a very large proportion of children and adolescents who are quite heavy and aren't moving much," said Barry Popkin, a nutrition professor. Popkin carries out an ongoing health-and-nutrition survey of 16,000 households in China. He says more kids today are overeating and putting on weight "quite quickly". In just ten years China's childhood obesity rate has doubled, with the greatest gains coming in urban areas. "In big cities it's a big problem." Some experts blame the extra fat on a range of factors, many of them tied to China's rapidly changing economy and culture. The diets of Chinese adults and children are far higher in calorie-laden meats, fish, eggs, dairy products, fats, and sugars than ever before. In addition, kids--especially city dwellers--are more sedentary today and spend more time indoors in front of homework, television, computer games, and the Internet. Shuwen Ng, a health economist, says that kids in China now have pocket money, and they spend a portion of it on junk food. Ng adds that advertising and peer groups influence kids' food choices. Certain foods, such as new candies or fast food, have attractive features. China's childhood obesity rate still lags that of the United States, where some 15 percent of kids are said to be obese. But the long-term effects are equally serious. Question: Which of the following is NOT the reason of China's childhood obesity? - Advertising on some new candies - High quality diets - Playing computer games for long time - Having pocket money
A: High quality diets

Q: Read the following article and select the best answer. Article: When I looked at the grade on my math paper my jaw almost dropped to the ground: a big "65" in bright red ink. I had never received such a terrible grade before. I was so ashamed that when I got home that afternoon I lied to my dad. I told him I got 85 and that the report wouldn't come until the end of the month. Dad smiled. His daughter would never lie about her grade, so he didn't doubt the unusual delay of my report. A month later, Dad casually asked me again about the report at the dinner table. He looked right into my eyes and asked for an answer. Having no choice, I told him that I had in fact got just 65 in my math final. I had lied because I didn't want to let him down. For a moment, he just looked at me. I would have preferred a telling off than that silence. Finally, Dad said, in a hurt voice, "You have already let me down, with your lie. I am not disappointed at your math score. That is no big deal - no one can be perfect all the time. But I am very disappointed in you. If you can't be honest with your dad, who can you be honest with? It's much easier to achieve a better grade than rebuild someone else's trust in you." Dad's words touched my heart. I couldn't forgive myself for having hurt his feelings. I took out the report that I had been hiding for weeks, handed to him and apologized, sincerely. I realized that my honesty is not only important to me personally, but to those around me that truly care about my well-being. In one of Shakespeare's plays a character says: "No legacy is so rich as honesty." After the crisis between Dad and me, I began to understand those words. Question: . Why did her father stay silent after his daughter told him that she had lied? - He didn't understand what his daughter had said. - He was angry that his daughter lied to him again. - He was unhappy with his daughter's bad score. - He was hurt that his daughter had lied to him.
A: He was hurt that his daughter had lied to him.
