阅读理解 Turning oil rigs into reefs saves money and marine life. Yet many greens oppose it.
When an offshore well stops producing oil, what should be done with the rig? One option is to haul it ashore, break it up and recycle it. This is expensive. For a big, deep-water oil or gas platform, it can cost $200m. Just hiring a derrick barge massive enough to do the job can cost $700,000 a day. But there is an alternative: simply leave most of the structure where it is. That is what you would expect a greedy oil firm to do: despoil the ocean just to save a lousy few million dollars. The surprise is, the cheap option may actually be greener.
More than 490 platforms in American waters have become reefs in the past three decades. The federal Bureau of Safety and Environmental Enforcement urges states to issue reefing permits. State coffers gain: oil firms typically hand over half the money they save by reefing.
Those savings vary greatly. Small platforms in shallow waters can often be removed for $10m, but sometimes for as little as $1m, according to DecomWorld, a consultancy. But for states with lots of offshore oil rigs, the windfalls soon add up. Mississippi pocketed an average of $625,000 for each of the 12 permits it has issued, according to Melissa Scallan of the state's Department of Marine Resources. Louisiana's take has averaged $270,000 per reefing—and the state has seen 336 of them, says Mike McDonough of the Louisiana Department of Wildlife and Fisheries.
Far bigger savings are possible in the deep waters off California. Four years ago the Golden State passed a law allowing reefing. Operators are loth to estimate costs publicly, but the Tulane University Energy Institute reckons that reefing the state's 27 platforms could save $2 billion. A platform or two could be retired as early as next year, though rising oil prices may mean they keep pumping longer.
The debate is likely to intensify. In the Gulf of Mexico some 400 platforms are now being decommissioned each year. Divers and many fishermen want more to be reefed; shrimpers complain that reefs prevent them from dragging nets across parts of the ocean floor. In California operators must decide quickly if they wish to turn redundant rigs into reefs. Until 2017 firms can keep 45% of the savings. After that the figure falls to 35% until 2023; then it drops to just 20%.
For now, the evidence suggests that reefing is a rare policy. It is both eco-friendly and pays for itself.
单选题 36.It is noted in Paragraph 2 that cheap option would be better if______.
【正确答案】 C
【答案解析】事实细节题。根据定位词可定位到文章的第二段，结尾处体现了题目的内容，之前的内容将是正确答案的位置，即simply leave most of the structure where it is(那便是放任不管)，而与这个信息相对应的选项为C项let the structure of the rigs as usual，故C项为正确选项。
单选题 37.According to the text "more rigs become reefs" would be benefit for______.
【正确答案】 D
【答案解析】事实细节题。根据定位词定位到文章的第三段，段尾处体现了关键词的内容，即State coffers gain：oil firms typically hand over half the money they save by reefing(州政府收益因此增加：石油公司通常需要上交一半从“珊瑚礁化”中节省出的钱。)由此可知州政府会因此受益，故D项为正确选项。
单选题 38.It can be inferred from the text that______ will save least from rectifying.
【正确答案】 B
【答案解析】推理判断题。根据定位词定位到文章的第四段，第四段第二句提到Small platforms in shallow waters can often be removed for $10m，but sometimes for as little as $1m(浅水水域的小型石油平台的拆除费用通常为1 000万美元，有时只需100万美元)。而第五段则说明深海区域会更省钱，由此可见，浅水区可节省的资金可能会更少，故B项为正确选项。
单选题 39.According to the reefing, ____ will mostly complain the policy.
【正确答案】 D
【答案解析】事实细节题。根据定位词定位到文章的第六段，该段第三句体现了养虾人的抱怨，即shrimpers complain that reefs prevent them from dragging nets across parts of the ocean floor．(而捕虾者却抱怨到，由于群礁的存在，他们无法在海底开展拖网作业。)故D项为正确选项。
单选题 40.From the text, we can see that the author's attitude towards reefing is______.
【正确答案】 C
【答案解析】态度方向题。做此类题目重点是在段落中找表明作者态度的标志，文章的最后一句体现了作者的观点，即It is both eco-friendly and pays for itself.(它既环保又能获得回报。)由此可见作者的态度是正面的，故C项为正确选项。
