Well, as if we needed one more reason to get our environmental act together, arecent U.N. report warns that the number and size of dead zones in the ocean isincreasing.如果我们需要一个理由一起进行环保行动,那么这个理由就是联合国最近的发布的一个报告警告说海洋死区的数量在不断增多,面积在不断增大。Dead zones are regions of oxygen-deprived water, where nothing can live.海洋死区是指海水中的氧气被消耗减少,以致没有东西能够生存。Theyrecaused by an excess of nutrients-usually nitrogen-released into the water.它们是由排入水中的过剩的营养物质引起的-这种物质常常是氮。When sewage, farm fertilizers, and emissions from vehicles and factories get washedinto the ocean, you get what experts call a “nitrogen cascade”.当污水,农田肥料,以及车辆和工厂的排放物被冲刷入海中时,就形成了专家所谓的“氮容器”。Tiny free-floating organisms known as plankton feed on all that untreated nitrogen, and multiply to such an extent that they deplete the oxygen supply inthe water.像浮游生物这些自由浮动的微小生物就是以未经处理的氮为食。它们繁殖到了如此的程度,以致于耗尽了水中供应的氧气。While fish may be able to swim away and avoid suffocation, slower-moving and bottom-dwelling creatures like lobsters, clams, and oysters often cant.尽管鱼可以游走避免窒息,但是那些缓慢移动和底栖的生物,列如:龙虾,蛤蚌,和牡蛎却不行。Also, the ocean might be a large place, but right now there are 146known dead zones, some of which span tens of thousands of square miles.或许海洋是一个广阔的地方,但是目前已知的海洋死区已有146个,其中一些跨度数万平方英里。One ofthe worst is where the Mississippi River drains into the Gulf of Mexico, anddumps fertilizer runoff from the Midwest.最严重的地方之一是密西西比河流入墨西哥湾的地方,这里倾倒着从中西部流失过来的肥料。Oh,no.Is there anything we can do?噢,不。有没有什么我们可以做的呢?We can reduce nitrogen emissions from cars andfactories, and implement better sewage treatment.我们可以减少汽车和工厂氮的排放量,并且实施更好的污水治理方法,We can plant new forest andgrasslands to soak up extra nitrogen and keep it out of the water.种植新的森林和草地来吸收多余的氮,并使氮远离水源。And we candevelop alternative energy sources that arent based on burning fossil fuels.我们还可以开发不以化石燃料燃烧为基础的替代能源。 201412/347903听力参考文本(文本与听力不全一致,敬请谅解):As everyone knows, the first presidential debate since the primaries is tonight, the first head-to-head clash between the two least popular presidential nominees ever.The atmosphere is more like that surrounding a Super Bowl, or maybe the boxing match ;Thrilla in Manila,; than a normal political event, and it is expected to draw perhaps a hundred million viewers, far more than any other in the history of televised debates.After all, as a story in the Boston Globe said yesterday, ;all thats at stake is the future of the free world.; Regardless of whether you think thats true, it is unquestionable that these debates, which are really sort of televised joint news conferences, have often had dramatic impact.Who can forget a shifty-eyed, perspiring and nervous Richard Nixon, looking uncomfortable, his stubble showing, as the handsome and tanned John F. Kennedy stole the show and won the election. Weve seen Ronald Reagan destroying Jimmy Carter with his gently mocking ;there you go again,; and Reagan slip badly, then recover, when the issue of his age came up four years later in his debates with Walter Mondale.There have also been memorable moments in the vice-presidential debates. Bob Dole lost points by being too nasty and aggressive when he was running for the second slot in 1976. Years later, Dole, who had a better sense of humor than both this years candidates put together, told me, ;I went for the jugular in that debate – my own.;Lloyd Bentsen never got to be vice president, because he was running with the hapless Michael Dukakis. But he destroyed any hope Dan Quayle had for moving higher with his devastating line, ;Jack Kennedy was a friend of mine. Senator, youre no Jack Kennedy.;But while we know these debates are crucial to the presidency, we often dont realize they can have consequences for other races as well. Four years ago, President Obama came to his first debate with Mitt Romney looking like he wasnt really prepared.The president seemed passive and inept, and observers overwhelmingly agreed Romney had won. The advantage didnt last, however; Obama picked himself up and decisively won the final two debates, after Romney made his famous ;I have binders full of women; gaffe.After the election, I said to Congressman Sander Levin that the debates didnt seem to have had any lasting effect. ;Ah, but you are wrong about that,; he said.He said Obamas weak performance in the first debate caused worried Democrats to shift millions in campaign spending from congressional races to the presidential contest.That, Levin believed, might have cost Democrats a chance to take back control of the U.S. House of Representatives. Im not sure about that. But it might have made a difference in one Michigan race. Theres a retired legislator named Gary McDowell in the little Upper Peninsula town of Rudyard who might be in Congress today if things had gone differently.He ran for Congress up north four years ago, and lost by one-half of one percent of the vote. He ran well ahead of the President in his district, and a little more money could have made the difference. This year, Democrat Lon Johnson is trying for the same seat.You can bet hes hoping Hillary Clinton does really well.201609/468593

They arived as larvae,swept in from the oacean by the tide.它们在幼体时期被海浪从大洋中带进来。Then as the tiny fish grow, they hop from one refuge to the next across the floor of lagoon to reach their final destination,back on the barrier reef itself.然后随着小鱼成长,它们在环礁湖底从一个避难所跳到另一个避难所,直到最终目的地外堡礁。As long as they hide amongst the corals and sea weed, they are relatively safe, the danger comes when they break cover.只要藏在珊瑚和海草中,它们就相对安全,如果从隐藏处中跑出来,危险就会来临。This baby Queensland Groper,may just be few cms long now, but one day hell weigh half a ton.这只幼年鞍带石斑鱼也许只有几厘米长,但迟早有一天它会长到半吨重。That if he lives that long, he cant stay hiding forever.前提是能活到那一天,它不能永远东躲西藏。Its dangers like this camouflaged Stone fish that forces all the lifes down here to find somewhere to hide.像伪装的石头鱼这样的危险掠食者迫使这里所有的生物都得找地方躲藏。The floor of lagoon is relatively flat and free of killers, like the plains in the dersert.环礁湖的海底相对平坦而没有特点,就像沙漠中的小平原。But every now and there you get a little oasis of the life,on this gong here is being heavily colonized by these ferthery stars, and its provides a vital kind of cover for junvile fish on their journey,both to the reef and their journey to the adulthood.但偶尔会看到小生命的绿洲,这块海绵已经变成海羽星的殖民地了,它为幼鱼在去往珊瑚礁的路途及成长的道路上提供了至关重要的保护。And that journey includes stopover of allmost anything that sticks out above sand,like this tube dewelling sea Anemone.这段旅程包括在任何高出沙子的地方做中途停留,就像这只管居千手佛。A carpet Anemone became a wellcoming road house...地毯海葵成为非常受欢迎的旅馆。201501/355101
