Question

阅读理解 　　After numerous false starts and broken promises, and nearly 184m gallons of crude oil gushed into the ecologically rich waters of the Gulf of Mexico, the Deepwater Horizon oil spill was at last brought under control on July 16．So far, both the long – term effects of the oil spill have been studied comprehensively． 　　According to the report by Friends of the Earth US, in the 85 days of the leak, 1,387 birds, 444 sea turtles, and 53 mammals were found dead in the Gulf．Nonetheless, the damage yet to be revealed will be far worse than a few dead birds and tar balls along 500 miles of coast．Dolphins, whale sharks and sea turtles numbers will almost certainly have been hit hard, and some populations may not ecover for years．Fish and shrimp – breeding habitats will have been hit．Deep coral ceefs, which can take centuries to grow, may also have been affected． 　　The oil that gushed also added to natural oil and gas leaks into Gulf waters．These occur all the time from the sea bed, and the US Department of Energy estimates that there may be 5,000 active “seeps” in the northern Gulf alone．One researcher calculated in 2000 that 500,000 barrels of oil-84m gallons-naturally gets into the Gulf each year, but is never cleaned up． 　　The Gulf is also heavily polluted by nitrogen(氮)and phosphorus(磷)from fertilisers and livestock waste washed down the vast Mississippi river from farms and industry．Every year, a massive oxygen-starved region known as the "dead zone" develops off the coast of Louisiana in which nothing can live．Last month, the US government’s National Oceanic and Atmospheric Administration(NOAA)said it expected this year’s "zone" to be between 6,500 and 7,800 square miles, the 10th largest ever．No one knows yet how the oil spill may affect it． 　　Fish will have suffered, but paradoxically the US government’s decision to ban commercial fishing from 88,000 sq miles of the Gulf during the clean-up in order to safeguard human health could actually help regenerate depleted fish stocks．The Gulf is one of the most overfished seas in the world, with many species in serious decline and some fisheries near collapse． 　　One wild card yet to be played is a major hurricane tearing through the Gulf of Mexico, Rough seas will hamper(防碍)efforts to finally seal the well and clean up the oil．The associated storm surges could also drive oil over barriers and further onto coastal land and into sensitive habitats．But the raging(狂暴的)of a storm could also break up the oil slick(浮油), allowing the bacteria that break it down to act more rapidly． (1) Fish and shrimp-breeding habitats will have been hit．Deep coral reefs, which can take centuries to grow, may also have been affected．The word habitats means ________． [　　] A． places under water B． natural homes of plants and animals C． some animals’ habits D． special places of interest (2) Nonetheless, the damage yet to be revealed will be far worse than a few dead birds and tar balls along 500 miles of coast．The underlined words refer to ________． [　　] A． that will be revealed later B． that has already been revealed C． that needs revealing D． that is been showing (3) The incident of natural oil and gas leaks into the Gulf of Mexico mainly involves the interests of ________． [　　] A． the U．S． B． Mexico C． Britain D． the U．S．and Britain
