阅读理解。 An Indian chief, Rising Sun, was concerned with how white men were expanding across the forests, plains, and mountains. Since his tribe was very small, and he wouldn't want them to be sent to reservations (居留地), he came up with a plan to save the people. His son, Falling Rock, was a strong, intelligent, and trustworthy young man. He asked Falling, Rock to travel across the whole of the country and talk to every tribe he met to convince them to join forces and fight against the white men. Falling Rock left in the spring with 4 other braves. When the leaves fell, one brave retumed to Rising Sun to tell him that they had contacted all the tribes in the desert SouthWest. When the snow began, another brave returned telling of their success with the Great Lakes tribes. A third brave arrived home just as the spring flowers bloomed and told how the strong tribes of the Rocky Mountains were ready. Finally, the last brave returned in high summer from the Eastem tribes with their promise to fight. This last brave also said that Falling Rock was now racing back to all the tribes, telling them to meet at the Mississippi river in the spring for the great war. When the snow melted, Rising Sun's small tribe waited in the Mississippi through spring and summer, but no other warriors (勇士) arrived. At the end of summer, Rising Sun sent braves out to track down Falling Rock. He got the news that all the tribes had waited to hear when the war was to take place, but Falling Rock had not been seen by any of them. The white soldiers surrounded Rising Sun's tribe. Rising Sun knew they could never win. Rising Sun promised to go peacefully to a reservation if the white men would help him find his lost son. This was a small price for avoiding a fight so the white men agreed. To this day, Rising Sun waits for his son to retum.
