问题     For hundreds of millions of years, turtles (海龟) 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 hand-carry the hatchlings (幼龟) down to the water’s edge lest they become 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 egg-laying females, as eggs and as hatchlings), we have neglected the years spend in the ocean. "The threat is from commercial 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 (恐龙) will meet its end at the hands of humans, leaving our descendants to wonder how creature so ugly could have won so much affection.
What can we learn from the first paragraph?
选项 A、Human activities have changed the way turtles survive.
B、Efforts have been made to protect turtles from dying out.
C、Government bureaucracy has contributed to turtles’ extinction.
D、Marine biologists are looking for the secret of turtles’ reproduction.
答案B
解析 细节题。根据题干定位到原文第一段。该段中提到，人类会拍摄自然纪录片来赞美海龟，会用GPS卫星和海洋生物学家来跟踪它们，还有志愿者提着海龟幼仔到水边以免它们被车头灯弄得迷失方向，政府为了保护它们在大西洋沿岸的主要筑巢地特意建造了一堵高耸的墙，由此可见，人们对海龟给予了很多的关注，B项表述正确，故选B。
