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 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 factors was ultimately responsible for the fall of the civilization of ancient Egypt?
A:Change of climate.
B:Famine.
C:Food.
D:Population growth.答案：A解析：第一段第一句表明，公元前2180年的饥荒使古埃及文明衰落，即使古埃及伟大的金字塔的建造者面对那场饥荒也无能为力。由此可知，作者提到金字塔的建造者，是为了表明即使是他们也无法拯救古埃及文明的衰落，故选D项。
第一段第二句提到，目前从尼罗河沉积的泥浆中收集的证据表明可将这次饥荒最终归咎于南面数千千米处发生的气候变化。因此气候变化是造成古埃及文明衰落的终极原因，而饥荒只是表层的因素，故选A项。
第四段表明，青尼罗河的泥浆与白尼罗河的泥浆中的同位素不同，通过分析尼罗河三角洲的泥浆中的同位素的差别，利兹大学的迈克尔.克罗姆算出了来自各个支流的沉淀物的比例。由此可知，青尼罗河和白尼罗河是尼罗河的支流，故选D项。
第五段表明，克罗姆发现4500年以前到4200年以前的干旱刚好发生在古埃及王国衰落之前。由此可以推断出，古埃及王国的衰落紧跟在一次旱灾之后，故选A项。

To us it seems so natural to put up an umbrella to keep the water off when it rains．But actually the umbrella was not invented as protection against rain．Its first use was as a shade against the sun．
Nobody knows who first invented it,but the umbrella was used in very ancient times．Probably the first to use it were the Chinese,way back in the eleventh century B.C.
We know that the umbrella was used in ancient Egypt and Babylon as a sunshade．And there was a strange thing connected with its use:it became a symbol of honor and authority．In the Far East in ancient times,the umbrella was allowed to be used only by royalty or by those in high office.
In Europe,the Greeks were the first to use the umbrella as a sunshade．And the umbrella was in common use in ancient Greece．But it is believed that the first persons in Europe to use the umbrella as protection against the rain were the ancient Romans.
During the Middle Ages,the use of the umbrella practically disappeared．Then it appeared again in Italy in the late sixteenth century．And again it was considered a symbol of power and authority．By 1680,The umbrella appeared in France,and later on in England.
By the eighteenth century,the umbrella was used against rain throughout most of Europe．Umbrellas have not changed much in style during all this time,though they have become much lighter in weight．It wasn't until the twentieth century that women's umbrellas began to be made,in a whole variety of colors.

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 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 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 Blue Nile mud in the river
would be relatively high.He found that one of these periods,from 4500 to 4200 years ago,
immediately came before the fall of the Egypt's Old Kingdom.
The weakened waters would have been disaster for the Egyptians."Changes that affect
food supply don't have to be very large to have a ripple（波浪）effect in societies."says
Bill Ryan of the Lamont Doherty Earth Observatory in New York.
Similar events today could be even more devastating,says team member Daniel
Stanley,a scientist 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 today
because the populations have increased dramatically."Which of the following factors was ultimately responsible for bringing down the civilization of ancient Egypt?
A:Change of climate.
B:Corruption.
C:Flood.

单选题What does the author imply by the final statement: “If that library had not burned down, maybe archeologists today would not have to spend so much of their time sorting through ancient trash!”?AThe author implies that if the library had not burned down, archeologists would be able to appreciate the full cultural legacy of King Ptolemy II Philadelphos.
BThe author implies that if the library had not burned down, scholars today would have not only the full works of Posidippus, but also those of Aeschylus, Sophocles, and Euripides.
CThe author implies that if the libravv had not burned down, the scrolls contained within the library would have decomposed before modern times in any event, because they would not have been preserved in the dry heat of the desert.
DThe author implies that if the library had not burned down, it might have contained more complete details about the life and culture of Hellenistic Egypt than can be found in the papyrus fragments from ancient refuse dumps.
EThe author implies that if the librarv had not burned down, the cultural awakening of the Renaissance might have occurred centuries earlier.
正确答案： C解析：
推断题。文章内容中提到纸莎草碎片一般是在古代垃圾中找到，它们为不能在其他史料中找到的人们日常生活进行了描述。所以可知本文最后一句话是作者在暗示，如果该图书馆没有被烧毁，那么考古学家可能可以从中找到关于人们日常生活的记录，而不用去生活垃圾中寻找，故D项的表述是正确的。 -

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 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

C:Food.
D:Population growth.答案：A解析：文章第一段提到“公元前2180年的饥荒毁灭了古埃及文明，即使古埃及伟大的金字塔 建造者面对那场饥荒也无能为力”，故选D。
文章第一段提到“目前从尼罗河沉积的泥浆中收集的证据将这次饥荒最终归咎于数千 千米以南地区发生的气候变化”，因此气候的变化是造成古埃及文明毁灭的根本性因素，而饥 荒只是表层的因素，故选A。
第四段指出：青尼罗河的泥浆与白尼罗河的泥浆的同位素标记不同。通过分析尼罗河 三角洲的泥浆的同位素差别，利兹大学的迈克尔?克罗姆算出了来自每个支流的沉淀物的比 例，由此可推断出青尼罗河和白尼罗河是尼罗河的支流，故选D。
第五段指出：克罗姆推断，在干旱季节，河水中青尼罗河泥浆的量相对较高。他发现了 其中一个时期，即4500到4200年前，是距离古埃及王国灭亡最近的时期。由此可以推断出， 古埃及王国的毁灭紧跟在一次旱灾之后。故选A。
此处devastating为形容词，意思是“破坏性的”。A项意思是“令人沮丧的”;B项意思是 “破坏的，毁坏的”;C项意思是“击败的”;D项意思是“令人担忧的，令人发愁的”。各项中只 有B项与devastating意义相近，故选B。第5部分：补全短文 -
