Egypt Felled by FamineEven ancient Egypt's mighty pyramid builders were powerless in the face of the famine that helped bring down their civilization around 2180 BC.Now evidence gleaned（搜集）from mud deposited by the River Nile suggests that a shift in climate thousands of kilometers to the south was ultimately to blame-and the same or worse could happen today.The ancient Egyptians depended on the Nile's annual floods to irrigate their crops.But any change in climate that pushed the African monsoons（季风）southwards out of Ethiopia would have diminished these floods.Dwindling（使减少）rains in the Ethiopian highlands would have meant fewer plants to establish the soil.When rain did fall it would have washed large amounts of soil into the Blue Nile and into Egypt,along with sediment（沉积物）from the White Nile.The Blue Nile mud has a different isotope（同位素）signature from that of the White Nile.So by analyzing isotope differences in mud deposited in the Nile Delta,Michael Krom of Leeds University worked out what proportion of sediment came from each branch of the river.Krom reasons that during periods of drought,the amount of the Blue Nile mud in the river would be relatively high.He found that one of these periods,from 4,500 to 4,200 years ago,immediately predated the fall of the Egypt's old Kingdom.The weakened waters would have been catastrophic for the Egyptians."Changes that affect food supply don't have to be very large to have a ripple effect in societies,"says Bill Ryan of the Lamont Doherty Earth Observatory（天文台）in New York."Similar events today coald be even more devastating,"says team member Daniel Stanley,a geoarchaeologist from the Smithsonian Institution in Washington, D.0."Anything humans do to shift the climate belts woulld have an even worse effect along the Nile system because the populations have increased dramatically."Which of the following statements is true?A:The White Nile is the trunk of the River Nile.B:The White Nile is the trunk of the Blue Nile.C:The White Nile is a branch of the Blue Nile.D:The White Nile and the Blue Nile are branches of the River Nile.

问答题Practice 5 The large river best known to the ancient Greeks was the Nile of Egypt. They spoke of the river with admiration and called Egypt “the gift of the Nile”. The reason for this was, first, that the Nile brought water to a rainless desert and, second, that once a year, the river overflowed its banks, leaving, as the water went back, a new layer of fertile soil. The flood waters carry in them soil (called silt) from the upper parts of the river valley to the lower parts, and so to the sea. But as the river meets the sea, the sea acts as a barrier and forces the river to drop the silt it is carrying. There are no tides in the Mediterranean to carry the silt away, so year after year it collects at the mouth of the Nile, and the river must find its way around islands of silt to the always more distant Mediterranean. In this way, a vast area of fertile soil has been built up at the mouth of the Nile and out into the sea. The river water splits up to form small branches winding across the area. To the ancient Greeks, the mouth of the Nile looked like the drawing. Now we sometimes name things after the letters of the alphabet they resemble: a U-turn, an I-beam a T-square, an S-bend, and so on. The Greeks did the same. The triangular area of land built up at the mouth of the Nile looked like the fourth letter of the Greek alphabet delta (Δ) and so this was the name they gave it. The word is now used for all areas of land formed at the mouth of rivers which flow into tideless seas, even when they are nor triangular in shape. The Mississippi delta, for example, is not shaped at all like the Greek delta, as you will see if you look at a map.
