英語作文范文：印第安“女兒國”的水利工程

　　There’s a Native American site in Ohio that appeared to be a fort. But recent discoveries by archaeologists at the University of Cincinnati show that’s not the case. Instead, it’s a two-thousand year old Shawnee water management system. It stretches out almost six kilometers. That’s much larger than what had been thought to comprise the so-called fort. It’s one of the largest such sites in the country.

　　What had been thought to be gates for military protection are actually a series of dams and irrigation canals. There are logs and clay bricks for damming; raceways for flowing water originate in far-off springs. The water was stored and channeled for irrigation. Drill cores show water sediments and clay.

　　The site demonstrates a sophisticated knowledge of engineering—which archaeologists did not realize that Native American communities might have. The site also reveals an emphasis on public works, rather than on war. So this discovery might rewrite a bit of history. Another interesting note: Shawnee remains from the time are typically of petite, graceful men—and robust, muscular women. So it was probably the women who built the water system. Which means even more history to rewrite.
