It may not be quite old enough to be the world's oldest living organism—that “honor” goes to the bristlecone pine tree (aged 5,000 years )—but,at 4,000 years of age,Leiopathes glaberrima,a deep­water coral species,does set the record for being the oldest animal living 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 dioxide—and of ocean acidification in dan 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 and his colleagues used radiocarbon dating to determine the coral's 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 specimens—those 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 comparison,that ocean quahog clam we mentioned a while back—aged 405 years—seems almost sprightly.

Notes:

acidification n.酸性 ②anemic adj.無活力的 ③subsurface adj.地下的 ④quahog clam圓蛤 ⑤sprightly adj.活潑的

長短句分析:What this suggests,he said,is that the harvesting of deep­water coral for jewelry should be completely banned.

句法點睛:本句中,“What this suggests”為主語,“he said”為插入語,that引導表語從句。

句意:他說,他提出的建議是,從深水珊瑚中採集珠寶的活動應該徹底制止。

【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待了4 000多年。研究它對我們研究海洋意義很大。科學家也提出了保護海洋珊瑚類的建議。

is the best title of the passage?

world's oldest living organism

st animal under the sea

to protect the corals grow

D.A great discovery

答案 B [主旨大意題。全文講述海洋的壽星,因此B項最合適。]

does the underlined word “clues” in the second paragraph mean?

ence. sure. C. Worth. e.

答案 A [詞義猜測題。聯絡第二段可知,Leiopathes glaberrima的發現對研究海洋提供了有力的線索與證據。]

's the value of the finding of the Leiopathes glaberrima?

shows which is the oldest in the ocean.

helps the scientists get more imformation about the ocean.

shows why the weather changes so much.

helps the scientists know how to live longer.

答案 B [推理判斷題。第二段講述了發現Leiopathes glaberrima的意義,因此可以得出答案為B。]

should the harvesting of deep­water coral for jewelry be completely banned?

use the jewelry has little value.

use the jewelry is hard to harvest.

use harvesting for the jewelry does great harm to deep­water coral.

use it is very dangerous.

答案 C [推理判斷題。從第三段中的.“because the corals grow at such an anemicrate,any level of harvesting would likely wipe out the remaining specimens”可知, 珊瑚的生長非常緩慢,稍微的破壞就會導致物種滅絕。]
