1. For hundreds of millions of years, turtles have struggled out of the sea to lay their eggs on sandy beaches, long bfore there were nature documentaries to celebrate them, or GPS satellites and marine biologists to track them, or volunteers to handcarry the hatchlings down to the waters edge lest they become disoriented by headlights and crawl towards a motel parking lot instead. 【分析】本句为复合句，主架为 turtles have struggled。For hundreds of millions of years 为介词短语作时间状语。before 为时间状语从句，该从句采用的是there be结构，主语为or连接的三个名词(词组)：natural documentaries，GPS satellites and marine biologists和volunteers，主语后的不定式均为主语的后置定语。lest以免引导状语从句，采用虚拟语气。 【译文】数百万年以来，海龟们都挣扎着从海里爬出来，到沙滩上产卵，那时候还没有自然纪录片来记录它们的活动，没有GPS卫星和海洋生物学家跟踪它们，没有志愿者用手把小海龟放到水边以防它们被桅灯搞得迷失方向而爬向旅馆的停车场。 2. The figures prompted Oceana to petition the government to upgrade the level of protection for the North Atlantic loggerheads from threatened to endangeredmeaning they are in danger of disappearing without additional help. 【分析】本句为复合句，主架为The figures prompted Oceana。to petition the government为不定式作prompted的状语，to upgrade the level of protection 为不定式作petition的状语。they are in danger help作meaning的宾语，相当于省略了引导词that的宾语从句。 |
