（首段指出人们为保护海龟采取措施。）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（纪录片，来自于document文件，word文件的后缀名为doc） to celebrate them, or GPS satellites and marine（海洋的） biologists to track them, or volunteers to hand-carry the hatchlings (幼龟) down to the water’s edge lest they become disoriented（失去方向，orient意为方向，美国学校新生皆有orientation） by headlights and crawl towards a motel parking lot（四级出现过，停车场） instead. （52的答案）A formidable（令人敬畏的） wall of bureaucracy（官僚主义，复习plutocrary和democrary） has been erected to protect their prime（主要的，复习primary和prime） nesting on the Atlantic coastlines. With all that attention paid to them, you’d think these creatures would at least have the gratitude(感激) not to go extinct（灭绝）.

（谈到海龟的数量仍在减少）

　　（53的答案）But Nature is indifferent to human notions（=idea，perspective，concept） of fairness, and a report by the Fish and Wildlife Service showed a worrisome drop in the populations of several species（种类，来自于special） of North Atlantic turtles, notably(来自于notion,意为特别地) 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（请愿，pet=seek寻找） the government to upgrade the level of protection for the North Atlantic loggerheads from “threatened” to “endangered（频临灭绝的）”—meaning they are in danger of disappearing without additional help.

　　（并分析其原因）

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.（54的答案） “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（利用） thousands of hooks on lines that can stretch for miles) take a heavy toll on turtles.

　　（呼吁采取更有效的措施）

Of course, like every other environmental issue today, this is playing out against the background of global warming and human interference（名词，来自于Interfere干涉） with natural ecosystems（=eco+system, 生态系统）. （55的答案）The narrow strips(带) of beach on which the turtles lay their eggs are being squeezed（紧缩，经济紧缩也用此词） on one side by development and on the other by the threat of rising sea levels as the oceans warm. Ultimately（=finally, eventually来自于ultimate） we must get a handle on those issues as well, or a creature that outlived(活得更长) the dinosaurs (恐龙) will meet its end at the hands of humans, （56的答案）leaving our descendants（后裔，来自于descend，反义词ascend） to wonder how creature so ugly could have won so much affection（喜爱，来自于affect）.
