Ancient Egypt Brought Down by Famine
Even ancient Egypt’s mighty pyramid (金字塔) builders were powerless in the face of the famine (饥荒) that helped bring down their civilization around 2180 BC. Now evidence collected 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 reduced these floods.
Declining rains in the Ethiopian highlands would have meant fewer plants to stabilize 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) from the White Nile.
Blue Nile mud has a different isotope (同位素) signature from that of the White Nile. So by analyzing iso

[单项选择]If sustainable competitive advantage depends on work-force skills, American firms have a problem. Human-resource management is not traditionally seen as central to the competitive survival of the firm in the United States. Skill acquisition is considered an individual responsibility. Labor is simply another factor of production to be hired—rented at the lowest possible cost—much as one buys raw materials or equipment.
The lack of importance attached to human-resource management can be seen in the corporate hierarchy. In an American firm the chief financial officer is almost always second in command. The post of head of human-resource management is usually a specialized job, off at the edge of the corporate hierarchy. The executive who holds it is never consulted on major strategic decisions and has no chance to move up to Chief Executive Officer (CEO). By way of contrast, in Japan the head of human-resource management is central--usually the second most important executive, after
A. Positive.
B. Praise.
C. Ironic.
D. Negative.
