[单项选择]Few foods are more alluring than chocolate. "Chocolate is a drug of abuse in its own category," jokes Dr. Louis Aronne. "It’s ahnost as if people have chocolate receptors in their brains. "
That may not be too far off the mark. In a recent book called "Breaking the Food Seduction," Dr. Neal Barnard contends that certain foods—including chocolate, cheese, red meat and practically anything combining sugar and fat—are just plain addictive. " It’s not that you lack willpower. These foods stimulate the release of chemicals in the brain’s pleasure center that keep you hooked. "
Besides tapping the brain’s own "feel good" chemicals, Barnard says, some of these foods contain drug-like molecules (分子) of of their own. Cheese delivers casomorphins, the same compounds in a mother’s milk that help an infant bond during nursing, he says, but cheese is even more powerful, because it delivers casomorphins in an undiluted form. The result: "We’re bonding to our refrigerators. "

[单项选择]There are few more sobering online activities than entering data into college-tuition calculators and gasping as the Web spits back a six-figure sum. But economists say families about to go into debt to fund four years of partying, as well as studying, can console themselves with the knowledge that college is an investment that, unlike many bank stocks, should yield huge dividends(红利).
A 2008 study by two Harvard economists notes that the "labor-market premium (额外收益) to skill"—or the amount college graduates earned that’s greater than what high-school graduates earned—decreased for much of the 20th century, but has come back with a vengeance (报复) since the 1980s. In 2005, the typical full-time year-round U.S. worker with a four-year college degree earned $50900, 62% more than the $31500 earned by a worker with only a high-school diploma.
There’s no question that going to college is a smart economic choice. But a look at the strange variations in tuition reveals that the choic

[填空题]Overprotective parents inhibit more than their kids’ freedom: they may also slow brain growth in an area linked to mental illness. Children whose parents are overprotective or neglectful are believed to be more susceptible to psychiatric disorders—which in turn are associated with defects in part of the prefrontal cortex.
To investigate the link, Kosuke Narita of Gunma University, Japan, scanned the brains of 50 people in their 20s and asked them to fill out a survey about their relationship with their parents during their first 16 years. The researchers used a survey called the Parental Bonding Instrument, an internationally recognized way of measuring children’s relationships with their parents. It asks participants to rate their parents on statements like "Did not want me to grow up", "tried to control everything I did" and "tried to make me feel dependent on her/him". Narita’s team found that those with overprotective parents had less grey matter in a particular area of the
