The images were shocking: Allison Samowitz and her twin sister, Jillian were watching the 2010 BP oil spill (溢出）on TV with their     sinking. "①We live right     the beach, and we heard many stories of how sea birds and sea creatures       because of sea pollution and how the spill      the ocean's ecosystem，" says Allison. "It was just devastating (毁灭性)，and we were      it would happen here." The       towns along the Gulf of Mexico didn't feel that far away from their little Golden Beach anymore. They decided to do      for the nature conservation.
The sisters studied the      habits of their friends and neighbors. "We're a(n)       town of 260 homes, and we found out only 20 percent of them      ！” Allison says.
②Moved to act, they first organized a town fair with demonstrations about how    people could make lasting changes to the environment. They       local companies to join them and the fair      a crowd of about 200 people. On the scene were trucks and booths (货摊）where volunteers and company workers accepted       electronic equipment, eyeglasses, clothes and books—all for recycling.
The girls are planning another     this year. "It's an education campaign," says Allison. "People don't know, but there are so many simple things they can do every day that can       the nature."
Allison now reports on the environment for her school's television station. Both girls devote their spare     to various recycling projects around the town，such as giving old toys to children's charities and collecting     clothes for the people in need.
And should anyone think that they're awfully single-minded, they are       . The sisters have many      other interests: ballet, volleyball，singing and deep-sea diving with their dad. "They're basically optimistic," said their dad.
