New research suggests that cutting daily sitting time to less than three hours might extend your life by two years. "Humans were designed to move. But modern lifestyles and office jobs rarely encourage us to walk around," says Peter Katzmarzyk, an expert at the University of Louisiana. "Sitting is common in our lives today. We sit while we're driving, eating and watching TV. And many of us sit for many hours at work." Katzmarzyk said. "We can't throw away physical activity. It's extremely important. We have 60 years of researchers showing us that." Katzmarzyk said. Katzmarzyk and other researchers are trying to discover how sitting all day affext our lifespans . "This is a relatively new area of study...Studies that have assessed the relationship between sitting and death or television viewing and death have been very rare in the last four or five years," said Katzmarzyk. Katzmarzyk and his colleagues analyzed data from these studies, which involved almost 167,000 adults. Then they turned to a government-run survey of Americans to find out exactly how much time people spend sitting and watching. Not only did the team find that U.S. citizens could live longer by sitting less, they found that cutting TV time to less than two hours a day could add an extra 1.4 years to their lives. People who've spent half their waking lives sitting down might well ask, "Is it ever too late to make a change?" "We would say 'No. It's never too late.' Physical activity is good for you at every age." Katzmarzyk said. Katzmarzyk says studying this problem has inspired his team to make a few changes in their own lives. They recommend a few simple changes: frequently getting up from your desk, taking walks at lunch time, and instead of e-mailing colleagues, walking over to their offices and talking face-to-face----all activities that can be enjoyable as well as life-extending. The best title of the text would be _ . A) What Is the Healthiest Lifestyle? B) Sitting for a Long Time Is Bad for Us C) Study Suggests Sitting Less Can Extend Life D) It Is Never Too Late to Change Our Way of Life

Although international students want to dive into American culture, it is easier to stay close to the families. "Most international students told me that they want to meet and make friends with as many Americans as they can," said Mark Galloway, Institute for International Studies (IIS) student adviser at prefix = st1 /StateUniversity. "But in reality, they are comfortable with being around people from their own country, if possible. " Testing of English as a Foreign Language (TOEFL) is an admission test for international students enrolling in American universities. Galloway said students' scores decreased when they spend less time with American students. More than 450 international students are on campus at MurrayStateUniversity. Thailand, Japan,South Korea,ChinaandGermanyare countries with the most students this semester, according to an IIS report. Wichien Eampromate, Thai Student Association President, said poor English ability and cultural differences make it difficult for Thai students to spend time with Americans.

On the other hand, Joon-Seong Bae, an exchange student from KoreaUniversity, said he tried to avoid hanging around other Koreans. But it is not easy for him. He said he is less comfortable with Americans because he cannot say everything he wants to say, and not all Americans are patient with his limited English. "There were two or three Americans and me," Bae said. "We talked about something. As time went by, I was kind of excluded because they talked to each other. While international students venture outside their comfort zones, American students also have the opportunity to be exposed to other cultures. "I know there are a lot ( of American students) who want to get to know international students," said Philip Lee, senior from Boonville,Indiana. "They are just uncomfortable. " Lee said he has learned about life from his international friends, although it is sometimes a challenge. " I can't live a... What Bae has experienced tells us that _ .

*Question*
Sparrow is a fast-food chain with 200 restaurants. Some years ago, the group to which Sparrow belonged was taken over by another company. Although Sparrow showed no sign of declining, the chain was generally in an unhealthy state. With more and more fast-food concepts reaching the market, the Sparrow menu had to struggle for attention. And to make matters worse, its new owner had no plans to give it the funds it required. Sparrow failed to grow for another two years. Until a new CEO, Carl Pearson, decided to build up its market share. He did a survey, which showed that consumers who already used Sparrow restaurants were extremely positive about the chain, while customers of other fast-food chains were unwilling to turn away from them. Sparrow had to develop a new promotional campaign. Pearson faced a battle over the future of the Sparrow brand. The chain's owner now favored rebranding Sparrow as Marcy's restaurants. Pearson resisted, arguing for an advertising campaign designed to convince customers that visits to Sparrow restaurants were fun. Such an attempt to establish a positive relationship between a company and the general public was unusual for that time. Pearson strongly believed that numbers were the key to success, rather than customers' speeding power. Finally, the owner accepted his idea. The campaign itself changed the traditional advertising style of the fast-food industry. The TV ads of Sparrow focused on entertainment and featured original songs performed by a variety of stars. Instead of showing the superiority of a specific product, the intention was to put Sparrow in the hearts of potential customers. Pearson also made other decisions which he believed would contribute to the new Sparrow image. For example, he offered to lower the rent of any restaurants which achieved a certain increase in their turnover . These efforts paid off, and Sparrow soon became one of the most successful fast-food chains in the regions where it operated. For what purpose did Pearson start the advertising campaign? A) To build a good relationship with the public B) To stress the unusual tradition of Sparrow C) To lean about customers' spending power. D) To meet the challenge from Marcy's restaurants.
