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: How did the experts carry out their research? Options: A: By examining health problems including overweight and smoking. B: By analyzing 173 studies on influences of media sources. C: By watching TV, playing video games and surfing the Web. D: By offering strong evidence that children become overweight.

Read the article and select the best answer. Article: I was not quite seventeen when I decided to join the US Marine Corps.My mother tried her best to talk me out of my dream, and then finally signed the papers that would permit me to enter the service. One day, nearly two years after the Philippines became my home, I was summoned to the office of Lieutenant Colonel Boyd.He seemed to be a kind man, but I was pretty sure that he hadn't called me in to pass the time of day. Standing before his desk, I waited nervously as he read through some paperwork.Then he looked up."Why, Private, haven't you written to your mother for more than six months?" I felt weak in my knees.Has it been that long? I thought. "I didn't have anything to say, Sir." Lieutenant Colonel Boyd told me that my mother had contacted the American Red Cross, which in turn communicated with my commanding officer about my failure to write. Then he asked, "Do you see that desk, Private?" "Yes, Sir." "Open the top drawer and you'll find some paper and a pen.Sit down right this minute and find something to say to your mother." "Yes, Sir." When I finished a brief letter, I stood before him again. "Private, I'm ordering you to find something to say to your mother at least once a week.Do you understand?" I did. Some 35 years later, my aged mother's mental condition was deteriorating, and I was forced to place her in a convalescent home .As I went through her belongings, I began inspecting the contents of an old cedar chest.At the bottom, tied with a bright red ribbon, I found a bundle of letters. They were the letters I had been ordered to write from the Philippines.I sat on the floor of her apartment that afternoon reading each one, tears streaming down my cheeks.I now realized how deeply, as a young man, had upset her by my lack of consideration. The lesson I learned may have been too late to help my mother, but it's still done me good.These days I don't need a commanding officer standing over me to write to my loved ones on a regular basis.
