[单项选择] No matter how large or notable the U. S. travel industry is or may become, it will always be members of a broader world society.

第三篇
Egypt Felled by Famine
Even ancient Egypt's mighty pyramid builders were powerless in the face of the famine that helped
bring down their civilization around 2180 B
C. 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一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（逐渐变少；使变少）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；沉积物）from the White Nile.
The Blue Nile mud has a different isotope（同位素；核素）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 could be even more devastating,"says team member Daniel Stanley,a
geoarchaeologist（地质考古学家）from the Smithsonian Institution in Washington ,
D.
C. " Anything humans
do to shift the climate belts would have an even worse effect along the Nile system because the populations
have increased dramatically."
The word"devastating"in the last paragraph could be best replaced by_______________.
A.frustrating
B.damaging
C.defeating
D.worrying
