【2011·江蘇金沙中學(xué)模擬】 D

The people who built Stonehenge in Southern England thousands of years ago had wild parties, eating barbecued pigs and breaking pottery． This is according to recent work by archaeologists--history experts who investigate how human beings lived in the past．

Archaeologists digging near Stonehenge last year discovered the remains of a large prehistoric village where they think the builders of the mysterious stone circle used to live． The village is about 4,600 years old, the same age as Stonehenge and as old as the Pyramids in Egypt． It is less than two miles from the famous ancient landmark and lies inside a massive man-made circular dirt wall, or "henge", known as the Durrington Walls．

Remains found at the site included jewellry, stone arrowheads, tools made of deer antlers, wooden spears and huge amounts of animal bones and broken pottery'． "These finds suggest Stone Age people went to the village at special times of the year to feast and party", says Mike Parker-Pearson from Sheffield University in England．

He said many of the pig bones they found had been thrown away half-eaten． He also said the partygoers appeared to have shot some of the farm pigs with arrows,  possibly as a kind of sport before barbecuing them．

An ancient road which led from the village to the River Avon was also found． Here, the experts think, people came 'after their parties to throw dead relatives in the water so the bodies would be washed downstream to Stonehenge．

Parker-Pearson believes Stonehenge was like a cemetery where ancient Britons buried the dead and remembered their ancestors． "The theory is that Stonehenge is a kind of spirit home to the ancestors．"

The recent discovery of the village within the Durrington Walls shows that Stonehenge didn't stand alone but was part of a much bigger religious site, according to Parker-Pearson．. That small difference is enough that the fish can live at the freezing temperature of the ice-salt mixture.

The scientists’ next research job was clear: Find out what kind of stuff in the fish’s blood kept it from freezing. Their research led to some really mysterious stuff made up of a protein (蛋白質(zhì)) never before seen in the blood of a fish. When this stuff was removed, the blood froze at seawater temperature. When it was put back, the blood again had its antifreeze character and a lowered freezing point.
