27、ing may have been a people the later Babylonians called Subarians. According to tradition, they came from the north and moved into Uruk in the south. By about 3100B.C, They Were apparently subjugated in southern Mesopotamia by the Sumerians, whose name became (5) synonymous with the region immediate

28、ly north of the Persian Gulf, in the fertile lower valleys of the Tigris and Euphrates. Here the Sumerians were already well established by the year 3000B.C. They had invented bronze, an alloy that could be cast in molds, out of which they made tools and weapons. They lived in cities, and they had b

29、egun to acquire and use capital. Perhaps most important, the Sumerians adapted writing (probably from the Subarians) into a flexible tool of (10) communication. Archacologists have known about the Sumerians for over 150 years. Archacologists working at Nineveh in northern Mesopotamia in the mid-nine

30、teenth century found many inscribed clay tablets. Some they could decipher because the language was a Semitic one (Akkadian), on which scholars had already been working for a generation. But other tablets were inscribed in another language (15) that was not Semitic and previously unknown. Because th

31、ese inscriptions mad reference to the king of Summer and Akkad, a scholar suggested that the mew language be called Sumerian. But it was not until the 1890s that archaeologists excavating in city-states well to the south of Nieveh found many thousands of tablets inscribed in Sumerian only. Because t

32、he Akkadians thought of Sumerian as a classical language (as ancient Greek and Latin are considered today), (20) they taught it to educated persons and they inscribed vocabulary, translation exercised, and other study aids on tablets. Working from known Akkadian to previously unknown Sumerian, schol

33、ars since the 1890s have learned how to read the Sumerian language moderately well. Vast quantities of tablets in Sumerian have been unearthed during the intervening years from numerous sites. （分数：1.00）(1).

Floridas ancient scrub demonstrates this principle. Its soil is pure silica, so ba

41、rren it supports only lichens as ground cover.(It does, however, sustain a sand-swimming lizard that cannot live where there is moisture or plant matter (5) the soil.) Its climate, despite more than 50 inches of annual rainfall, is blistering desert plant life it can sustain is only the xerophytic,

42、the quintessentially dry. Its altitude is a mere couple of hundred feet, but it is high ground on a peninsula elsewhere close to sea level, and its drainage is so critical that a difference of inches in elevation can bring major changes in its plant communities. Its aspect is flat, direct, brutaland

43、 subtropical. (10) Floridas surrounding lushness cannot impinge on its desert scrubbiness. This does not sound like an attractive place. It does not look much like one either; Shrubby little oaks, clumps of scraggly bushes, prickly pear, thorns, and tangles. “It appear Said one early naturalist,“ to

44、 desire to display the result of the misery through which it has Passed and is passing.“ By our narrow standards, scrub is not beautiful; neither does it meet (15) our selfish utilitarian needs.

45、 about such a place?

R is relict seashore, tossed up millions of years ago when ocean levels (20) wer

46、e higher and the rest of the peninsula was submerged. That ancient emergence is precisely what makes Lake Wales Ridge so precious: it has remained unsubmerged , its ecosystems essentially undisturbed, since the Miocene era. As a result, it has gathered to itself one of the largest collections of rar

47、e organisms in the world. Only about 75 plant species survive there, but at least 30 Of these are found nowhere else on Earth. （分数：1.00）(1).
