[Q]: Article: Even before historian Joseph Ellis became a best-selling author, he was famous for his vivid lectures. In his popular courses at Mount Holyoke College in Massachusetts, he would often make classroom discussion lively by describing his own fighting experience in Vietnam. But as Ellis's reputation grew--his books on the Founding Fathers won both the National Book Award and the Pulitzer Prize ---the history professor began to entertain local and national reporters with his memories of war. Last year, after The Boston Globe reported Ellis's experience in the Vietnam war, someone who knew the truth about Ellis _ Last week The Boston Globe revealed that Ellis, famous for explaining the nation's history, had some explaining to do about his own past. "Even in the best of lives, mistakes are made," said Ellis. It turned out that while the historian had served in the Army, he'd spent his war years not in the jungles of Southeast Asia , but teaching history at West Point ( ). He'd also overstated his role in the antiwar movement and even his high-school athletic records. His admission shocked colleagues, fellow historians and students who wondered why someone so successful would beautify his past. But it seems that success and truthfulness don't always go hand in hand. Even among the successful achievers, security experts say, one in ten is deceiving. And, oddly, people often beautify their past once they're famous, says Ernest Brod of Kroll Associates, which has conducted thousands of background checks. Then what makes them do it? Psychologists say some people succeed, at least in part, because they are uniquely adjusted to the expectations of others. And no matter how well-known, those people can be haunted ( ) by a sense of their own shortcomings. "From outside, these people look anything but fragile," says Dennis Shulman, a psychoanalyst. "But inside, they feel hollow, empty,"
Answer: taught history at a military school
[A]: While Ellis served in the Army, he _

[Q]: Article: One of the United States' social problems is the breakdown of the two-parent family. Today, millions of American children grow up without fathers. Too often, these children lack the love and help they badly need and which they would ordinarily receive from not one but two parents. In the old days, American parents placed the needs of their children above their own. At present, however, nearly one half of all new marriages end in divorce, with often troubling results for their children. Worse, every year, thousands of teenage, unmarried Americans become mothers outside marriage, with generally terrible results for the mothers and children alike and for American society more generally. However, Chinese continue to value whole marriages. This is not to say that Chinese marriages are all perfect. They certainly are not, judging from increasing rates of divorce and extramarital affairs-but the willingness of Chinese to set aside their own needs and stay together for the sake of the children is admirable and worthy of study. Families, in whatever form they may take, are important to Americans. If one was to ask a group of Americans what is the dearest to them, the majority would say"family".And yet, so many Americans spend much more time at work, that is, beyond the formal forty-hour work week-than they do with their own families. Obviously, the USA is one of the most powerful in the world, owing in large measure to"workaholism" . It seems to me that Chinese generally find a better balance between work and family needs than many Americans do. I don't see the number of workaholics in China that I do in the United States(or American organizations in China).Instead, average Chinese usually head home right after work(in the office or field),have meals together, and spend time with their family members. What's more, Chinese try to make more time for grandparents, uncles, aunts and cousins than many Americans; in many cases, multigenerational families live together. Of course, like many facts of Chinese society, this is all changing; increasing numbers of"New Chinese"are working longer hours and spending less time with their families than ever before. Still, while Americans do value their loved ones, I think we have something to learn from the Chinese about finding the proper balance between work and family.
Answer: there is something about family for Americans to learn from China

[Q]: Article: There are a lot of social networking sites these days. In order to make relationships between people strong, sites like Facebook, Twitter and QQ have become a daily "must visit" site. In fact, many people spend all day in front of the computer or are busy with their phones only to spend time on these sites. Social networking sites provide facilities that enable people to communicate with their friends without spending time meeting them in person. In addition, they can play games. But what is quite surprising is that these sites not only give you pleasure, but can also increase risks of diseases in your body. Despite their primary purpose, these sites make people more isolated . "Sending a message through sites can cause side effects that are very big in the body's biological changes," said Dr Aric Sigman, a psychologist, according to DailyMail. Increased isolation may alter the workings of immune response to the feelings of anger and others. People become angry easily. In the journal, Dr. Sigman says that it can increase the risk of cancer, strokes, heart attacks and dementia . Researchers found that the amount of time people used to meet face to face had decreased greatly since the increased use of the electronic media in 1987. To save time, people prefer to meet virtually rather than face to face; Education today even uses an online system that allows school-aged children not to come out of their rooms. Parents spend less time with their children, like the cases in England. The habit of having dinner together decreases, while the number of people who choose to work online at home increases. "The electronic media may also reduce the ability of children and adults in social interaction, as long as they are isolated. Social networking sites should help us improve the quality of life, but what happens is the opposite, they are not a tool to improve, but a tool to replace," said Dr Sigman.
