Unit 5 The power of natureⅠ.阅读理解(建议用时16′)A[2017·长沙一模]Evidence of violent storms that destroyed a lost town known as Britain's Atlantis has been uncovered W1. The finds were uncovered off the coast of Dunwich, Suffolk—a small village which in the 11th century was one of the largest towns in England.The town was hit by a series of storms in the 13th and 14th centuries and is now largely below the sea.Researchers said sediment (沉积物) gathered from the cliffs independently proved the historical W2 record.“They were like the south coast storms of 2013, at least once a year for decades，” Professor David Sear, of the University of Southampton, said.The three­year research on Dunwich has been funded W3 by Touching the Tide, a ￡900,000 Heritage Lottery Fund plan to explore the changing Suffolk coast.A diver used ultrasound (超声波) to “illuminate” findings on the seabed, and the marshes (沼泽) and eroding cliffs were surveyed.“It offers a marvelous W4 history of climate change and coastal erosion，” said Prof. Sear with regard to the findings.In the 11th century, Dunwich was the 10th largest town in England, but now has about 120 residents.Two great storms in 1286 and 1326 resulted in P1 the loss of its harbour and started its decline W5. Prof. Sear said analysis showed how people gave up on Dunwich after 1338, when another great storm choked up the port for good, and food production declined. “Sediment gathered from the cliff s，” he said, “independently confirmed the sequences of storms recorded in the historical record.”The underwater research has been carried out using acoustic (声音的) imaging technology, and has unearthed a series of buildings. We found the ruins of about four churches and we've also found ruins of what we think was a toll house. We've also found shipwrecks (沉船), which no one's known before.A dig in 2015 discovered evidence of Dunwich's prehistoric origins, as well as evidence that it was a prosperous Saxon port, prior to its rapid growth following the Norman invasion.Bill Jenman, from Touching the Tide, said，“We found loads of P2 pottery, a lot more than we've found before, sort of High Medieval—the peak of the wealth of Dunwich. We know it w as a fairly major town in the Anglo­Saxon period.”篇章导读：本文讲述了研究人员发现了英国一个衰落的小镇“Dunwich”被猛烈的暴风雨摧毁的新证据。

The world Meteorological (气象的) Organization (WMO) said its modeling suggested a “fairly large potential W2 for an El Nino, most likely by the end of the second quarter of 2016”．The El Nino phenomenon occurs every two to seven years, when the trade winds that circulate surface water in the tropical (热带的) Pacific start to weaken.WMO pointed out Tuesday that since last December, trade winds had weakened and there had been a significant W3 warming of the waters below the surface in the central Pacific.“While there is no guarantee W4 this_situation will lead to an El Nino event, the longer the trade winds remain weakened, and subsurface temperatures stay significantly warmer than average, the higher chances are，” it said.Two thirds of climate models predicted that the phenomenon would begin sometime between June and Augu st, with one­fifth suggesting it could start as early as May, and the remaining predicting no El Nino this year, it said.It is often followed by a return swing of La Nina, which is characterized W5 by unusually cool ocean surface temperatures in the central and eastern tropical Pacific.“El Nino has an important warming effect on P1 global average temperatures，” Jarraud cautioned, stressing that combined with P2 warming from greenhouse gases such events had “the potential to cause a sharp rise in global average temperature”．篇章导读：本文是一篇报道，周二联合国气象机构发出警告：今年太平洋很有可能出现厄尔尼诺现象。
