2019年10月27日托福阅读真题+题目+答案：The River Nile in Ancient Egypt

The special character of the Nile, which made it central to ancient Egyptian culture, was its annual inundation (flooding). During June the river began to rise, and a quantity of green water appeared. The color is said to have resulted from the brief period of reproduction of myriad minute organisms. During August the Nile rose rapidly and assumed a muddy red color created by the rich red earth brought into its waters by its tributaries. The Nile continued to rise until mid-September, then remained at that level for two or three weeks. In October it rose again slightly, then began to fall gradually until May, when it reached its lowest level.

The Nile has created a convex shaped in an elevated curve floodplain. In convex floodplains, sediments (clays and silts) are deposited by flood waters, making the land nearest the river have the highest elevation. The convex floodplain is marked by natural levees that form elevated barriers immediately adjacent to the river. These levees rise a few meters above the seasonally inundated lowlands. When the Nile floods, the water covers most of the low-lying land up to the edge of the desert. ■When the floods subside, the waters are trapped behind the levees and prevented from returning to the river. ■The benefit of such topography is obvious: the water can be used where it stands or can be channeled to other areas as dictated by agricultural needs.

■Ancient records, those preserved both in texts and in the visible evidence on ancient devices for measuring water levels called nilometers, indicate that a flood of six meters was perilously low and that one of nine meters was high enough to cause damage to crops and villages. ■ A flood of seven to eight meters was ideal in that low-lying areas and basins throughout the whole valley would be flooded up to the edge of the rising ground of the desert, but towns, villages, and dikes that served as paths and water barriers remained above the water level.。。。。。余下托福阅读真题原文省略！
