单选题. The age at which kids first fall victim to bullying could influence how strongly they are affected, suggests a new study. And surprisingly, it is not the youngest kids who are hurt the most in the long term. Bullying can have long-lasting effects, but particularly when it begins in adolescence (青春期), the researchers say. People subjected to either verbal or physical bullying are known to be at greater risk for developing depression, anxiety disorders or to behave violently. But not everyone reacts in this way. Children bullied for the first time before they hit puberty (青春期) seem to get over it, but those who are victimized for the first time late on in puberty seem to become more aggressive or are more likely to turn to drink as a means of coping. These are the conclusions of psychologist Matthew Newman and colleagues from the University of Texas at Austin, US. The team gave questionnaires to nearly 1,500 college students regarding their experience of physical and psychological bullying before puberty—before high school—and in puberty—at high school. They assessed mood and mental state, judging by signs of anxiety or depression, such as sleeplessness. The group was also questioned about how they would react to certain challenges, such as being humiliated (羞辱) or provoked (激怒). People who were bullied all revealed slightly higher levels of stress. But while those bullied earlier in life seemed to respond normally to provocation, people bullied for the first time late in puberty are more withdrawn and sensitive to violence. There are also sex differences between those bullied for the first time during puberty, with females more likely to react aggressively when provoked and males are much more likely to turn to alcohol to escape bad situations. The best solution in all cases was strong social support, whether from friends, family or school. Those with no one to share their problems with suffered the most. So perhaps it is best not to shelter children completely from bullying early on, suggests Newman. "They may get stressed, but unhealthy coping really jumps out when they are bullied for the first time later on." The effects are likely to be related to the developing stress hormone (应激荷尔蒙) system, which matures during puberty, he concludes.11. What is one factor that decides the influence of bullying? ______

单选题. You've now heard it so many times; you can probably repeat it in your sleep. President Obama will no doubt make the point publicly when he gets to Beijing: the Chinese need to spend more; they need to consume more; they need—believe it or not—to become more like Americans, for the sake of the global economy. And it's all true. But the other side of that equation is that the U.S. needs to save more. For the moment, American households actually are doing so. After the personal-savings rate dipped to zero in 2005, the shock of the economic crisis last year prompted people to snap shut their wallets. In China, the household-savings rate exceeds 20%. It is partly for policy reasons. As we've seen, wage earners are expected to care for not only their children but also their aging parents. And there is, to date, only the flimsiest (脆弱的) of publicly-funded health care and pension systems, which increases incentives for individuals to save while they are working. But China is a society that has long esteemed personal financial prudence (谨慎) for centuries. There is no chance that will change anytime soon, even if the government creates a better social safety net and successfully encourages greater consumer spending. Why does the U.S. need to learn a little frugality (节俭)? Because healthy savings rates are one of the surest indicators of a country's long-term financial health. High savings lead, over time, to increased investment, which in turn generates productivity gains, innovation and job growth. In short, savings are the seed corn of a good economic harvest. The U.S. government thus needs to act as well. By running constant deficits, it is dis-saving, even as households save more. Peter Orszag, Obama's Budget Director, recently called the U.S. budget deficits unsustainable and he's right. To date, the U. S. has seemed unable to have what Indiana Governor Mitch Daniels has called an "adult conversation" about the consequences of spending so much more than is taken in. That needs to change. And though Chinese leaders aren't inclined to lecture visiting Presidents, he might gently hint that Beijing is getting a little nervous about the value of the dollar—which has fallen 15% since March, in large part because of increasing fears that America's debt load is becoming unmanageable. That's what happens when you're the world's biggest creditor: you get to drop hints like that, which would be enough by themselves to create international economic chaos if they were ever leaked. (Every time any official in Beijing deliberates publicly about seeking an alternative to the U. S. dollar for the $ 2.1 trillion China holds in reserve, currency traders have a heart attack.) If Americans saved more and spent less, consistently over time, they wouldn't have to worry about all that.1. How did the economic crisis affect Americans? ______

单选题. Housing officials say that lately they are noticing something different: students seem to lack the will, and skill, to address these ordinary conflicts. "We have students who are mad at each other and they text each other in the same room," says a teacher. "So, many of our roommate conflicts are because kids don't know how to negotiate a problem." And as any pop psychologist will tell you, bottled emotions lead to silent seething (不满) that can boil over into frustration and anger. At the University of Florida, emotional outbursts occur about once a week, the university's director of housing and residence education says. "It used to be: 'Let's sit down and talk about it,'" he says. "Over the past five years, roommate conflicts have intensified. The students don't have the person-to-person discussions and they don't know how to handle them." The problem is most dramatic among freshmen; housing professionals say they see improvement as students move toward graduation, but some never seem to catch on, and they worry about how such students will deal with conflicts after college. Administrators speculate that reliance on cell phones and the Internet may have made it easier for young people to avoid uncomfortable encounters. Why express anger in person when you can vent in a text? Facebook creates even more friction as complaints go public. "Things are posted on someone's wall on Facebook: 'Oh, my roommate kept me up all night studying,'" says Dana Pysz, an assistant director in the office of residential life at the University of California, Los Angeles. "It's a different way to express their conflict to each other." In recent focus groups at North Carolina State University, dorm residents said they would not even confront noisy neighbors on their floor. Administrators point to parents who have fixed their children's problems their entire lives. Now in college, the children lack the skills to attend to even modest conflicts. Some parents continue to intervene on campus.1. What does the word "address" (Para. 1) mean? ______
