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 sites 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 sea turtles, notably loggerheads (红海龟) , 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 they 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 long-line fishers (which can deploy thousands of hooks on lines that can stretch for miles) take a heavy toll(损失) 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 a creature so ugly could have won so much affection.
We can learn from the first paragraph that_________.
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
推断题。第一段倒数第二句指出,政府机构已经建立强大的保护墙来保护它们在大西洋海岸线上的主要栖息地;最后一句进行了补充说明,由于人类对它们的关注,这些生物也许就不会面临灭绝的危险了。综合理解可知,人类做出了很大的努力来保护海龟免遭灭绝的厄运。所以B项为正确答案。
