2 阅读理解。 In eighteen seventy-seven, the American government decided to move the Nez Perce Indians from their land. The government had set up a reservation for them in Idaho. Chief Joseph did not want to leave the land. It was holy ground. It contained the bones of his father and mother. But, like his father in earlier times, Chief Joseph knew it would be hopeless to stay and defend the land. There were too few Indians to win a war against the white men. And so in June of eighteen seventy-seven, the Nez Perce left their home in the Wallowa Valley. They left quickly. They were able to take only a small part of what they owned, and just a few cattle and Appaloosa horses. When the Indians reached the Snake River, the water was very deep and ran very fast with melted snow from the mountains. Chief Joseph and his people made boats from sticks and dried animal skins to cross the river. While the Indians were busy, a group of white men came and stole some of the cattle waiting at the edge of the river. The other chiefs demanded that Joseph call a meeting. Two of the chiefs, White Bird and Toohoolhoolzote, spoke for War, but Joseph held different opinion. Some of the young men in White Bird"s group were very angry. That night, they rode into the countryside and killed eleven white persons. During all his years as chief, Joseph had tried to keep the peace. Now he saw there was no hope. Although he and his young men had taken no part in the killings, he knew that the white men would blame all of the Indians. Chief Joseph said, "I would have given my own life if I could have undone the killing of the white men." Many Nez Perce fled. Chief Joseph remained, because his wife was about to have a baby. After she gave birth, he and his family joined the others in White Bird Canyon to the south. Joseph wanted to lead the people to safety in the flat lands of Montana. But the United States army quickly sent horse soldiers to follow them. They were extremely tired when they reached White Bird Canyon. An Indian-carrying a white flag-walked forward to meet them. A soldier shot him. With that shot, war between the Nez Perce and the United States began. 1. Why didn"t Chief Joseph want to leave the land? A. He thought the reservation in Idaho wasn"t satisfying.
