President Barack Obama claimed progress Wednesday in his second-term drive to combat climate change but said more must be done to address a generational problem. One year after unveiling an aggressive plan, Obama said new【C1】______limits on power plants, renewable energy projects and new【C2】______for green technology have cleared the way for further action in the U.S. and abroad, despite steadfast【C3】______from much of Congress. "When you take those first steps, even if they"re【C4】______, and even if there are politics sometimes, you start【C5】______momentum and you start mobilizing larger and larger communities," Obama said. Obama"s【C6】______served as a progress report for his climate plan, which the president【C7】______out last June. Twelve months later, much of the plan is in【C8】______although the most ambitious steps are still up in the air and will take years to be【C9】______realized. Change won"t be instantaneous, Obama【C10】______. "There"s no silver bullet." Indeed, many of the steps he"s taking are【C11】______, limited in scope by hostility from both parties to putting a【C12】______on carbon pollution, which would require new laws from Congress. Still, Obama said he"s seeking to【C13】______the problem but cutting it up into smaller pieces. "We"re moving, and it"s making a【C14】______," he told a supportive crowd at the League of Conservation Voter"s annual dinner. The environmental group【C15】______Obama early in his 2008 campaign.【C16】______on the international front, momentum has been obscure.【C17】______global climate talks next year in Paris, there are fresh【C18】______that some countries are urging others to resist【C19】______moves to curb carbon. That could discourage even bigger polluters from【C20】______. 【C2】

Several years into a campaign to get kids to eat better and exercise more, child obesity rates have appeared to stabilize, and might be poised for a reversal. But a study published Monday in the journal PNAS suggests that among adolescents, the【C1】______ signs are limited to those from better-educated, more【C2】______families. Among teens from poorer, less well-educated families, obesity has【C3】______to rise. That class-gap was not【C4】______in younger children. But as children neared【C5】______, the class differences became increasingly obvious. 【C6】______between rich and poor in obesity rates are not new, and they are only one of many health gaps that make poor patients sicker and more likely to die【C7】______than richer ones. But if the public health message on obesity "has not diffused【C8】______across the population," this gap could【C9】______efforts to stem a tidal wave of【C10】______obesity-related diseases in the years ahead. Researchers from Harvard University"s Kennedy School of Government found that【C11】______ activity may account largely for the【C12】______ trend in obesity between rich and poor. If public health experts are to prevent childhood obesity and【C13】______drive down future obesity among adults, they"ll have to figure out【C14】______less advantaged kids don"t get as much exercise, the authors of the latest study say. Yes, lack of【C15】______centers, playgrounds, and streets and sidewalks that【C16】______walking, biking and playing are important, they wrote. But, they added, "this is not the whole story." Among children with parents who【C17】______high on the socioeconomic scale, participation in high school sports and clubs has increased. But among their【C18】______from families of lower educational【C19】______and income, such participation has【C20】______. 【C5】

B. childhood
C. fatherhood
