Are manners dead? Cellphones and social networking may be killing off old civilities and good graces, but a new generation of etiquette experts is rising to make old-fashioned protocols relevant to the new generation. Their goal is to help young people navigate thorny tech-age minefields, like invitations on social networking sites and online dating, not to mention actual face-to-face contact with people. Perhaps the fastest-growing area of social advice is what's been termed "netiquette". There are online tutorials on using emoticons in business emails, being discreet when posting on social networks and re-posting too many microblog messages. What is the passage mainly about? A. Good manners of a new generation in the modern society.B. Passing down etiquette from parents to young people.C. Updating etiquette in the new generation.D. Good civilities of a new generation in their daily life.

Given the lack of fit between gifted students and their schools, it is not surprising that such students often have little good to say about their school experience. In one study of 400 adults who had achieved distinction in all areas of life, researchers found that three-fifths of these individuals either did badly in school or were unhappy in school. Few MacArthur Prize fellows, winners of the MacArthur Award for creative accomplishment, had good things to say about their precollegiate schooling if they had not been placed in advanced programs. Anecdotal (名人轶事) reports support this. Pablo Picasso, Charles Darwin, Mark Twain, Oliver Goldsmith, and William Butler Yeats all disliked school. So did Winston Churchill, who almost failed out of Harrow, an elite British school. About Oliver Goldsmith, one of his teachers remarked, "Never was so dull a boy. " Often these children realize that they know more than their teachers, and their teachers often feel that these children are arrogant, inattentive, or unmotivated. Some of these gifted people may have done poorly in school because their gifts were not scholastic. Maybe we can account for Picasso in this way. But most fared poorly in school not because they lacked ability but because they found school unchallenging and consequently lost interest. Yeats described the lack of fit between his mind and school: "Because I had found it difficult to attend to anything less interesting than my own thoughts, I was difficult to teach." As noted earlier, gifted children of all kinds tend to be strong-willed nonconformists. Nonconformity and stubbornness (and Yeats’s level of arrogance and self-absorption) are likely to lead to Conflicts with teachers. When highly gifted students in any domain talk about what was important to the development of their abilities, they are far more likely to mention their families than their schools or teachers. A writing prodigy (神童) studied by David Feldman and Lynn Goldsmith was taught far more about writing by his journalist father than his English teacher. High-IQ children, in Australia studied by Miraca Gross had much more positive feelings about their families than their schools. About half of the mathematicians studied by Benjamin Bloom had little good to say about school. They all did well in school and took honors classes when available, and some skipped grades.The main point the author is making about schools is that(). A．they should satisfy the needs of students from different family backgrounds. B．they are often incapable of catering to the needs of talented students. C．they should organize their classes according to the students' ability. D．they should enroll as many gifted students as possible.

The use of credit cards among college students has risen to an all-time high, according to a report released by the student loan company Sallie Mae.According to the report, college students own an average of 4.6 credit cards, and the mean credit card debt has increased from ,169in2004t03,173 in 2008. But students who discussed credit card use with their parents were less likely to overspend, according to the report."Students indicated that they wanted more information about smart money management and they wanted it earlier than even college," said Patricia Nash Christel, a specialist in saving, planning, and paying for college at Sallie Mae.Christel said the credit problems are related to rising college tuitions and lack of family savings. Many households are simply underestimating the cost of paying for college while the convenience of credit card use—especially online—provides a constant temptation for college-age students.Contrary to the findings of the study, Harvard students and affiliates have remained relatively unaffected by the trend of increasing debt.Gene Foley, president of the Harvard University Employees Credit Union, said, "On the Harvard campus, we have not really seen students who look like they're getting out of control or getting into trouble with their credit cards." Foley added that there has not been a spike in the demand for credit or requests for cash advances recently.Foley said that part of this stability at Harvard is a result of the credit union's attempts to maintain the limits it sets on student credit cards. The credit union arranges for financial literacy and education programmes to teach students about the dangers of credit card abuse.However, Harvard has not been completely unaffected by the changes in consumer financial behaviour. Although applications for credit cards at the Harvard union have not increased, the amount drawn from each card has risen, said Foley.In addition, Harvard students may be succumbing to the same temptations as other undergraduates across the nation. "There's about 4 or 5 major credit card lenders, and some of them have preyed on students," Foley said.He said that direct marketing to college-age students has resulted in the increased credit card usage and debt recently.Nonetheless, Foley warned that the disadvantages of excessive credit card debt do not outweigh the advantages offered by this form of payment."While students need to be cautious about credit cards, it doesn't mean you shouldn't have one," he said.1.
