Kristy, 28, a cook in La Cross, often wondered what she’d do in a life-threatening situation. On August 29, 1997, she got hex answer. While she was driving on a road, a big truck hit its head on a pick-up car(敞篷小货车). The pick-up burst into flames. Kristy rushed out and ran to the pick-up. Two farmers, Dean Bernhard, 51, and his brother Donald, 44, were inside, When she got close, Kristy could see the unconscious driver. The other man was under the passenger seat. Says Kristy, "The smells were sickening(令人作呕的). I was afraid the truck would blow up and kill us all." The driver of the big truck was struggling to open the passenger door, so Kristy rushed to the driver’s side. Finally they opened the door. She reached in, seized the driver and, to her horror, felt her hands sink into his chest. She quickly dragged the man to safety on the roadside, then hurried back. As Kristy stared down the ditch(沟) with the passenger, the pick-up blew up. She jumped on top of him and they both rolled to safety. When the police arrived a while latex, Kristy started crying, "I want my mum." In fact she cried for the next three months. Today, the two farmers, each the father of two children, are good friends with Kristy. To show their deep appreciation, they bought her a ring with nine diamonds -- one for each member of their immediate families, and the, ninth for her.

When coming to save Donald and Dean Beruhard, Kristy never thought that she ______.
