[1]One Friday night in May 2010, Oliver and Ione Kleven heard angry shouts coming from their front lawn(草坪). Ione, 65, stepped onto the porch（門廊） and saw two men in dark clothes struggling with something on the ground—right where she and her grandson had planted a flower bed the weekend before.

[2] “Go fight somewhere else!” she shouted, worried her plants would get damaged. At the sound of her voice, the face of a boy appeared from beneath the two men. He looked 14. “They’re trying to kill me!” the boy screamed. Ione ran toward them and, without hesitation, caught the boy’s arm, pulling him out.

[3] “Leave him alone!” she shouted. When the men stood up, Ione saw what looked like a sharp object in one man’s hand. When she turned back toward the boy, he was moaning（呻吟） in pain and holding his stomach. The attackers began to move in on the boy again when Ione’s husband shouted: “Get lost!” The two men walked quickly and quietly across the street and drove off in a dark car.

[4]“I have to get to the hospital!” the boy cried. He lifted his shirt, and Ione could see a bloody wound on his stomach. Oliver hugged the trembling(發(fā)抖的) boy while Ione caught her cell phone and car keys inside the house. She handed the phone to Oliver. “Call 911,” she told him. “I’m going after them.” Ione took off but was unable to find the car.

[5]The Klevens then learned what had happened . Earlier that night, as the boy waited for his parents to pick him up from the high school across the street from the Klevens’ house, two men approached and demanded his wallet. When he refused, one of the men hit him in the face. The boy ran across the street. The men caught up with him, and one hurt him in the back and stomach with a sharp knife. That’s when Ione stepped in.

57. Why did Ione shout at the two struggling men? (within 8 words)
