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,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 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 a creature so ugly could have won so much affection.
54.What constitutes a major threat to the survival of turtles according to Elizabeth Griffin?
[A] Their inadequate food supply.
[B] Unregulated commercial fishing.
[C] Their lower reproductive ability.
[D] Contamination of sea water.

对于几亿年，龟（海龟）奋斗的海上产卵的沙滩，很久以前有自然纪录片庆祝他们，或GPS卫星和海洋生物学家追踪，
或志愿者随身携带小海龟（幼龟）到海水的边缘，以免他们成为大灯迷失方向和抓取走向汽车旅馆停车场代替。强大的官僚机构已建墙，以保护他们的主要在大西洋海岸筑巢。与所有支付给他们的注意，你会认为这些动物将至少有感激没有消失。
但是，大自然无动于衷的人公平的观念，以及由鱼类和野生动物的报告显示，在北大西洋的海龟，特别是相持不下，它可以长到高达400磅的人口数种令人担忧的下降。南佛罗里达州排料口，最大，下降了50％，在过去十年中，根据伊丽莎白格里芬
与环保团体世界海洋组织的海洋生物学家。这些数字促使欧西那请愿，要求政府提高对北大西洋争执的“威胁”到“濒危”保护水平-这意味着他们在没有额外的帮助消失的危险。
这就引起了明显的问题：还有什么吃的，从我们想要的，无论如何？原来，根据格里芬，虽然我们已做了保护女性的卵子铺设和幼体），而忽略了这些年来他们在花费数周他们在陆地上花费（如蛋的海龟，好工作海洋。 “这种威胁来自商业捕鱼，”格里芬说。
拖网渔船（它在水中阻力大网，沿洋底）和延绳钓渔民（可以部署了数千名线，可延伸数英里挂钩）将对龟沉重的代价。
当然，像所有其他环境问题的今天，这是发挥出对全球变暖和自然生态系统的人为干扰的背景。海滩上的海龟产卵被挤压在一边的发展和作为海洋变暖，海平面上升的威胁，另一方面的狭长。
归根结底，我们必须得到处理这些问题以及，或不再营运的生物恐龙（恐龙）将满足人类手中结束，我们的后代留下来不知道如何让一个生物丑恶能够赢得这么多的感情。
54。什么构成的重大威胁海龟的生存根据伊丽莎白格里芬？
[A]他们的粮食供应不足。
[B]不规范的商业捕鱼。
[C]他们的生育能力降低。
[D]污染海水。
我也不知道选哪个 你自己看着办吧
求个分...谢谢LZ
