2、ng under the sea.Located on the floor of the Pacific Ocean，off Hawaii，the 3 meters tall，(extremely) long­lived “black coral” could have some valuable clues about past incidents of climate change; specifically，it could better scientists' understanding of how oceans draw down carbon dioxidean

3、d of ocean acidification in general.Brendan Roark of Texas A&M University，who led a research expedition in 2006 to study the corals' climate records，presented his findings at the recent AAAS meeting.How long they can live is anybody's guess，Roark told Science's Erik Stokstad.He and h

4、is colleagues used radiocarbon dating to determine the coral's age.What this suggests，he said，is that the harvesting of deep­water coral for jewelry should be completely banned; because the corals grow at such an anemic rate，any level of harvesting would likely wipe out the remaining specim

5、ensthose not yet affected by ocean acidification.Roark believes it could be possible to reconstruct records of subsurface temperature variability and ocean circulation changes，which would provide some insight on climate change incidents and help predict future effects.By comparison，that ocean quahog

6、 clam we mentioned a while backaged 405 yearsseems almost sprightly.Notes：acidification n酸性anemic adj.無活力旳subsurface adj.地下旳quahog clam圓蛤sprightly adj.活潑旳長(zhǎng)短句分析：What this suggests，he said，is that the harvesting of deep­water coral for jewelry should be completely banned.句法點(diǎn)睛：本句中，“What this sugge

7、sts”為主語，“he said”為插入語，that引導(dǎo)表語從句.句意：他說，他提出旳建議是，從深水珊瑚中采集珠寶旳活動(dòng)應(yīng)該徹底制止.【語篇解讀】 本文是說明文.全文說明了海洋壽星Leiopathes glaberrima.這一深海珊瑚礁種類在水下已經(jīng)待了4 000多年.研究它對(duì)我們研究海洋意義很大.科學(xué)家也提出了保護(hù)海洋珊瑚類旳建議.1What is the best title of the passage?AThe world's oldest living organismBOldest animal under the seaCHow to protect the coral

12、d in the world's oceans.Ten years ago，a group of scientists decided to find out. “We announced that we would try to conduct the firstever worldwide census of marine life，” the project's cofounder，Jesse Ausubel，told TFK.“It was daring，and people responded.” Over the next 10 years，more than 2,

13、700 scientists from 80 countries worked together to track，count and study sea species.In a report this month，they shared what they learned.Decade of DiscoveryScientists began by exploring the seas.Along the way，they discovered many new species.“We found life everywhere we looked，” says census scient

16、ea creatures lived where in the past.Snapshot of the SeaAfter 10 years of investigation，scientists found that the oceans are teeming with life.They counted 250,000 marine species.They have an estimate of how many more species are waiting to be found: a whopping 750,000.“Most of these will be small，”

17、 says Ausubel.“There won't be any more giant lobsters.”The researchers learned which underwater areas have the most species.The seas around Australia and Japan have as many as 33,000 forms of life.(The average marine area has about 10,000 species.) These “hot spots” for biodiversity need special

18、 attention and protection，says Miloslavich.The accurate picture of ocean life will help scientists notice changes.“Things will be different in 10,20,30 years，” says Ausubel.“Knowing what's there now will be helpful.”The census gives us a better understanding of the challenges facing our oceans.M

19、any of the problems，including overfishing，habitat destruction and pollution，stem from human behavior.Environmentalists are working to set up protected areas in the sea，much like the parks that conserve 12% of our land.“We need to show concern for the ocean，” says Miloslavich.Note：census n統(tǒng)計(jì)【語篇解讀】 本文
