24、based on the following passage.Just off the coast of Southern California sits Santa Cruz Island, where a magical creature called the island fox 26 . A decade ago, this islands ecosystem was in 27 . Wild pigs attracted golden eagles from the mainland, and those flying 28 crashed the fox population. S
25、o the Nature Conservancy launched a 29 war against the pigs, complete with helicopters and sharp shooters.And it worked. Today, federal agencies are pulling the island fox from the Endangered Species List. Its the fastest-ever recovery of a mammal, joining peers like the Louisiana black bear as glow
26、ing successes in the history of the Endangered Species Act.But the recovery of Santa Cruz Island isnt just about the fox. The Nature Conservancy has 30 war on a multitude of invasive species here, from sheep to plants to the 31 Argentine ant. “Our philosophy with the island has always been, OK, 32 t
27、he threats and let the island go back to what it was,” says ecologist Christina Boser. And it appears to be working. Native plants are coming back, and the fox once again bounds about carefree.But keeping those foxes from harm will occupy Boser and her colleagues for years to come. You see, humans a
28、re still allowed on Santa Cruz Island, and they bring dogs. So Boser has to vaccinate her foxes against various diseases. “Were obligated to keep a pulse on the population for at least five years after the foxes are delisted,” says Boser. That includes tagging the foxes and 33 their numbers to ensur

Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You m
31、ay choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2. Do Parents Invade Childrens Privacy When They Post Photos Online?A When Katlyn Burbidges son was 6 years old, he was performing some ridiculous so
32、ng and dance typical of a first-grader. But after she snapped a photo and started using her phone, he asked her a serious question:“Are you going to post that online?” She laughed and answered, “Yes, I think I will.” What he said next stopped her. “Can you not?”B Thats when it dawned on her: She had
33、 been posting photos of him online without asking his permission. “Were big advocates of bodily autonomy and not forcing him to hug or kiss people unless he wants to, but it never occurred to me that I should ask his permission to post photos of him online,” says Burbidge, a mom of two in Wakefield,
34、 Massachusetts. “Now when I post a photo of him online, I show him the photo and get his okay.”C When her 8-month-old is 3 or 4 years old, she plans to start asking him in an age-appropriate way, “Do you want other people to see this?” Thats precisely the approach that two researchers advocated befo
35、re a room of pediatricians (儿科医生) last week at the American Academy of Pediatrics meeting, when they discussed the 21st century challenge of “sharenting,” a new term for parents online sharing about their children. “As advocates of childrens rights, we believe that children should have a voice about
36、 what information is shared about them if possible,” says Stacey Steinberg, a legal skills professor at the University of Florida Levin College of Law in Gainesville.D Whether its ensuring that your child isnt bullied over something you post, that their identity isnt digitally “kidnapped”, or that t
37、heir photos dont end up on a half dozen child pornography (色情) sites, as one Australian mom discovered, parents and pediatricians are increasingly aware of the importance of protecting childrens digital presence. Steinberg and Bahareh Keith, an assistant professor of pediatrics at the University of
38、Florida College of Medicine, say most children will likely never experience problems related to what their parents share, but a tension still exists between parents rights to share their experiences and their childrens rights to privacy.E “Were in no way trying to silence parents voices,” Steinberg
39、says. “At the same time, we recognize that children might have an interest in entering adulthood free to create their own digital footprint.” They cited a study presented earlier this year of 249 pairs of parents and their children in which twice as many children as parents wanted rules on what pare
40、nts could share. “The parents said, We dont need ruleswere fine, and the children said, Our parents need rules,” Keith says. “The children wanted autonomy about this issue and were worried about their parents sharing information about them.”F Although the American Academy of Pediatrics offers guidel
41、ines recommending that parents model appropriate social media use for their children, it does not explicitly discuss oversharing by parents. “I think this is a very legitimate concern, and I appreciate their drawing our attention to it,” David Hill, a father of five, says. He sees a role for pediatr
42、icians to talk with parents about this, but believes the messaging must extend far beyond pediatricians offices. “I look forward to seeing researchers expand our understanding of the issue so we can translate it into effective education and policy,” he says.G Theres been little research on the topic
43、, Steinberg wrote in a law article about this issue. While states could pass laws related to sharing information about children online, Steinberg feels parents themselves are generally best suited to make these decisions for their families. “While we didnt want to create any unnecessary panic, we di
44、d find some concerns that were troublesome, and we thought that parents or at least physicians should be aware of those potential risks,” Steinberg says. They include photos repurposed for inappropriate or illegal means, identity theft, embarrassment, bullying by peers or digital kidnapping.H But th
45、ats the negative side, with risks that must be balanced against the benefits of sharing. Steinberg pointed out that parental sharing on social media helps build communities, connect spread-out families, provide support and raise awareness around important social issues for which parents might be the
46、ir childrens only voice.I A C.S. Mott survey found among the 56 percent of mothers and 34 percent of fathers who discussed parenting on social media, 72 percent of them said sharing made them feel less alone, and nearly as many said sharing helped them worry less and gave them advice from other parents. The most common topics they discussed included kids sleep, nutrition, discipline, behavior problems and day care and preschool.J “Theres this peer-to-peer nature of health care these days with
