Smith is a 26-year-old single mother with a daughter. She was moving into her a-partment in Atlanta, Georgia early on the morning of March 12, when a man followed her and put a gun to her head. "I was opening my door and I felt really, really afraid," she said in a TV interview last week. The man was Brian Nichols, 33. He was suspected of killing three people on March 11 and later of killing a federal(联邦的)agent. The local police were searching for him. Nichols tied Smith up with tape, but released her after she repeatedly begged him not to take her life. "I told him if he hurt me, my little girl wouldnt have a mummy," she said. In order to calm the man down, she read to him from the purpose-driven life, a bestselling religious book. He asked her to repeat a paragraph about "what you thought your purpose in life was what talents were you given". And the two of them discussed this topic. Smith said, "I basically just talked to him and tried to gain his trust. " Smith said she asked Nichols why he chose her. "He said he thought I was an angel sent from God, and we were Christian sister and brother," she said. "And that he was lost, and that God led him to me. " She even cooked breakfast for the man before he allowed her to leave. She said Nichols was surprised when she made him breakfast and that the two of them watched television coverage(报道)that the police hunt for him. "I cannot believe thats me," Nichols told the woman. Then, Nichols asked Smith what she thought he should do. She said, "I think you should turn yourself in. If you dont, lots more people are going to get hurt. " Eventually, he let her go. Then she called the police. A US $ 60 000 reward had been posted for Nicholss capture. Authorities said they did not yet know if Smith should get that money.How did Smith feel when she saw a robber with her?A．Frightened.B．Frustrated.C．Nervous.D．Calm.
