【正文】 ased on the following passage.　　There is nothing new about TV and fashion magazines giving girls unhealthy ideas about how thin they need to be in order to be considered beautiful. What is surprising is the method psycholo gists at the University of Texas have e up with to keep girls from developing eating disorders. Their main weapon against superskinny (role) models: a brand of civil disobedience dubbed “body activism.”　　Since 2001, more than 1,000 high school and college students in the . have participated in the Body Project, which works by getting girls to understand how they have been buying into the notion that you have to be thin to be happy or successful. After critiquing (評論) the socalled thin ideal by writing essays and roleplaying with their peers, participants are directed to e up with and execute small, nonviolent acts. They include slipping notes saying “Love your body the way it is” into dieting books at stores like Borders and writing letters to Mattel, makers of the impossibly proportioned Barbie doll.　　According to a study in the latest issue of the Journal of Consulting and Clinical Psychology, the risk of developing eating disorders was reduced 61% among Body Project participants. And they continued to exhibit positive bodyimage attitudes as long as three years after pleting the program, which consists, of four onehour sessions. Such lasting effects may be due to girls’ realizing not only how they were being influenced but also who was benefiting from the societal pressure to be thin. “These people who promote the perfect body really don’t care about you at all,” says Kelsey Hertel, a high school junior and Body Project veteran in Eugene, Oregon. “They purposefully make you feel like less of a person so you’ll buy their stuff and they’ll make money.”二For hundreds of millions of years, turtles (海龜) have struggled out of the sea to lay their eggs on sandy beaches, long before there were nature documentaries to celebrate them, or GPS satellites and marine biologists to track them, or volunteers to handcarry the hatchlings (幼龜) down to the water’s edge lest they bee disoriented by headlights and crawl towards a motel parking lot instead. A formidable wall of bureaucracy has been erected to protect their prime nesting on the Atlantic coastlines. With all that attention paid to them, you’d think these creatures would at least have the gratitude not to go extinct.　　But Nature is indifferent to human notions of fairness, and a report by the Fish and Wildlife Service showed a worrisome drop in the populations of several species of North Atlantic turtles, notably loggerheads, which can grow to as much as 400 pounds. The South Florida nesting population, the largest, has declined by 50% in the last decade, according to Elizabeth Griffin, a marine biologist with the environmental group Oceana. The figures prompted Oceana to petition the government to upgrade the level of protection for the North Atlantic loggerheads from “threatened” to “endangered”—meaning they are in danger of disappearing without additional help.　　Which raises the obvious question: what else do these turtles want from us, anyway? It turns out, according to Griffin, that while we have done a good job of protecting the turtles for the weeks they spend on land (as egglaying females, as eggs and as hatchlings), we have neglected the years spend in the ocean. “The threat is from mercial fishing,” says Griffin. Trawlers (which drag large nets through the water and along the ocean floor) and longline fishers (which can deploy thousands of hooks on lines that can stretch for miles) take a heavy toll on turtles. 　　Of course, like every other environmental issue today, this is playing out against the background of global warming and human interference with natural ecosystems. The narrow strips of beach on which the turtles lay their eggs are being squeezed on one side by development and on the other by the threat of rising sea levels as the oceans warm. Ultimately we must get a handle on those issues as well, or a creature that outlived the dinosaurs (恐龍) will meet its end at the hands of humans, leaving our descendants to wonder how creature so ugly could have won so much affection.
