"Our suggestion is for people to increase their intake, through diet or a vitamin supplement," Dr. Cedric Garland said in a telephone interview. Garland's research team reviewed 63 studies, including several large long-term ones, on the relationship between vitamin D and certain types of cancer worldwide between 1966 and 2004. "There's nothing that has this ability to prevent cancer," he said, urging governments and public health officials to do more to fortify foods with vitamin D.Garland is part of a University of California at San Diego Moores Cancer Center team that published its findings this week online in the American Journal of Public Health. Vitamin D is found in milk, as well as in some fortified orange juice, yogurt and cheeses, usually at around 100 international units (IU) a serving. People might want to consider a vitamin supplement to raise their intake to 1000 IUs per day, Garland said, adding that it was well within the safety guidelines established by the National Academy of Sciences. The authors said that taking more vitamin D could be especially important for people living in northern areas, which receive less vitamin D from sunshine. African Americans, who don't produce as much of the vitamin because of their skin colour, could also benefit significantly from a higher intake, the authors said. Question: According to the passage, people are advised to take more Vitamin D because _ . Options: A: it is nutritious B: it can't harm people's health C: it is not taken enough every day D: it can lower cancer risk

The morning paper lay beside his plate. He always read the "Deaths" first, and then he knocked once on the table. One of my sisters brought his toast ,already buttered for him. Usually he said nothing, but once I heard him say, "I love you very much, Edith. I would love you more if you buttered my toast on both sides." He read the paper all through breakfast. Two knocks on the table meant "I am ready for my tea." If a single knock followed, that meant "More toast, please." After breakfast he said, "Boots." The paper was spread for him over the back of an armchair. Yesterday's paper was put on the chair for his feet, and his boots were brought to him, freshly cleaned. He read standing, at the same time putting on his boots. With one boot finished, he said, "Bus." At that point one of the girls went outside to the garden gate and waited there. Her job was to stop the bus when it came. It came early sometimes, and it had to wait for my father. "Overcoat, hat." One of my sisters had already brushed his overcoat. Now she held it open for him and guided his arms into it. Another girl came with his hat, nicely brushed. "Handkerchief, pipe ." They were brought and put, with his tobacco , into his pockets. He looked out of the window and said either "Walking stick" or "Umbrella". It was handed to him. Ready now, he was still reading the paper. He did not put it down until he heard the shout "Bus coming!" Then he kissed my mother and went out. The girls breathed freely. How lucky a man is to have a wife and five daughters at home! Question: What was the father's favorite? Options: A: Reading newspaper. B: Having bread buttered on both sides. C: Giving instructions. D: Being clean and tidy

Article: Spending a lot of time watching TV, playing video games and surfing the Web causes a lot of healthy problems to children such as overweight and smoking, US researchers said yesterday. U.S. experts analyzed 173 studies on how media sources influence the physical health of children and adolescents . The studies, mostly carried out in the prefix = st1 /United States, largely focused on television, but some looked at video games, films, music, computer and Internet use. Three quarters of them found that increased media viewing was connected with poor health. The studies offered strong evidence that children who get more media exposure are more likely to become overweight, start smoking and begin earlier sexual activity than those who spend less time in front of a screen, the researchers said. Studies also showed more media exposure is linked to drug and alcohol use and poorer school performance. "We were pretty surprised by the number of studies that showed these negative health results," said one of the researchers in the report. For decades, experts have worried about the effect on young viewers of the violence and sexual content in some TV programs, movies and video games. Another issue is that kids are spending time sitting on a couch watching TV or playing computer games when they could be running around outside. One study found that children who spend more than eight hours watching TV per week at age 3 are more likely to be overweight at 7. And research showed that many USchildren watch far more. Another study showed TV and other media content can have a deep influence on children's attitudes and beliefs, particularly among teens. A US study published in November showed that adolescents who watched more programs with sexual themes had a higher risk of becoming pregnant or causing a pregnancy. Thirteen of 14 studies that evaluated sexual behavior found a connection between media exposure and earlier sexual behavior, the researchers said. Question: According to the passage, too much media exposure may cause the following EXCEPT _ . Options: A: drug and alcohol use B: overweight, smoking, sexual problem C: progress in school subjects D: poor health results and violence
